Understanding the Legal Requirements for a Danish Sole Proprietorship

Starting a business can be one of the most rewarding endeavors in an individual's life. For many aspiring entrepreneurs in Denmark, a sole proprietorship (Enkeltmandsvirksomhed) may be the preferred business structure due to its simplicity. However, navigating the legal requirements associated with establishing a sole proprietorship involves a thorough understanding of the laws, regulations, and necessary steps. This article aims to provide a comprehensive overview of the legal requirements for starting and running a Danish sole proprietorship.

What is a Sole Proprietorship?

A sole proprietorship is a type of business owned and operated by a single individual, without separation of the business entity and the owner. This structure is particularly appealing in Denmark due to its straightforward formation and management processes. The owner possesses complete control over the business and is personally liable for all business debts and obligations. This liability means the owner's personal assets may be at risk if the business incurs debts or faces legal action.

The Benefits of a Sole Proprietorship in Denmark

Before delving into legal requirements, it's beneficial to outline some advantages of operating as a sole proprietorship:

1. Simplicity of Operation: The sole proprietorship structure is relatively simple to establish and administer. There are fewer formalities compared to other business structures, such as corporations.

2. Complete Control: As the sole owner, you have complete decision-making authority, enabling you to steer your business in your chosen direction without needing consensus from partners or shareholders.

3. Taxation Benefits: Sole proprietors typically benefit from simpler tax processes, as income is reported on the owner's personal tax return, avoiding the complexities of corporate taxation.

Lower Costs: The cost of setting up and maintaining a sole proprietorship is generally lower than other business forms, making it a favorable option for many small entrepreneurs.

Legal Framework for Sole Proprietorships in Denmark

Understanding the legal framework is crucial when starting a sole proprietorship in Denmark. This includes knowing the relevant laws and regulations stipulated by the Danish Business Authority (Erhvervsstyrelsen) and other governmental bodies.

Step-by-Step Guide to Registering Your Danish Sole Proprietorship

Registering a sole proprietorship in Denmark involves several steps, which are outlined below.

Step 1: Choose a Business Name

The first step in registering a sole proprietorship is selecting a unique business name. The name must clearly indicate that the business is a sole proprietorship. It cannot include words that suggest a different type of business entity, such as “aktieselskab” (A/S), which indicates a corporation.

Step 2: Obtain a CPR Number

Every sole proprietor in Denmark must obtain a CPR (civil registration number). This number is necessary for tax identification and social security contributions. If you reside in Denmark, gaining a CPR number is usually straightforward as long as you are legally residing in the country.

Step 3: Register Your Business

All businesses operating in Denmark are required to register with the Danish Business Authority through the Central Business Register (CVR). This register is crucial for any operational business, and registration can typically be completed online.

To register, the following information is generally required:

- Business name

- Owner's name and CPR number

- Address of the business

- Description of business activities

- Date of commencement

After registering, you will receive a unique CVR number for your business.

Step 4: VAT Registration (if applicable)

If your business expects to have an annual turnover exceeding a certain threshold (currently DKK 50,000), you are required to register for Value Added Tax (VAT). VAT registration can also be completed through the Danish Business Authority.

You must charge VAT on your services or goods, submit VAT returns regularly, and maintain records of your sales.

Step 5: Understand and Comply with Tax Obligations

Sole proprietors are taxed on their profits as individuals, meaning the business income is reported on the personal income tax return. It's important to keep accurate records of all income and expenses for tax purposes.

Denmark has a progressive tax system whereby higher incomes are taxed at higher rates. Additionally, sole proprietors may be liable for contributions to social security and pensions.

Step 6: Get Necessary Licenses and Permits

Depending on the nature of your business, you may need specific licenses or permits to operate legally in Denmark. For instance, if you're running a restaurant, you will require food handling permits. Research and ensure you have the correct licenses for your specific business activities.

Step 7: Set Up an Accounting System

Keeping track of your financial situation is vital for any business. As a sole proprietor, you are advised to maintain an accurate accounting system to record all income and expenses. This practice not only helps in tax reporting but also provides insights into your business's financial health.

You can maintain your accounts manually, use accounting software, or hire an accountant to manage your books.

Understanding Your Rights and Responsibilities

Operating a sole proprietorship in Denmark comes with specific rights but also responsibilities. Familiarizing yourself with these is essential.

Rights

1. Autonomy: As a sole proprietor, you have the right to make decisions independently, directing your business as you see fit.

2. Profit Retention: You are entitled to keep all profits generated by your business, subject to personal income tax obligations.

3. Flexible Business Operations: You can adapt your business model and operational strategies as market conditions change without the need for formal processes.

Responsibilities

1. Personal Liability: Bear in mind that you are personally liable for all debts and obligations incurred by the business. If your business fails or faces lawsuits, your personal assets may be at risk.

2. Regulatory Compliance: You must comply with all relevant laws, including tax laws and regulatory requirements. Failure to comply can result in penalties or even business closure.

3. Business Record Keeping: You are required to maintain detailed records of your business transactions, employee information (if applicable), and other relevant documentation to comply with tax and labor laws.

Insurance Considerations for Sole Proprietors

While not legally mandated, obtaining appropriate insurance coverage is highly recommended for sole proprietors to safeguard against potential risks. Here are some insurance options to consider:

Public Liability Insurance

This insurance protects against claims from third parties for injuries or property damage arising from your business activities.

Professional Indemnity Insurance

If you provide professional services, this insurance protects against claims of negligence or wrongdoing in your professional advice or services.

Business Interruption Insurance

This insurance helps cover lost income and ongoing expenses if your business operations are disrupted due to unforeseen events.

Contents Insurance

If your business involves physical assets, such as inventory or equipment, contents insurance protects against loss or damage to those items.

Potential Challenges and Solutions

Starting and running a sole proprietorship in Denmark, while relatively straightforward, does present a set of challenges. Recognizing these potential challenges and knowing how to address them is crucial for sustainability.

Access to Funding

Many sole proprietors struggle to secure funding due to the perception of higher risk by banks and investors. To enhance your chances of obtaining funding, consider:

1. Demonstrating a Solid Business Plan: Present a robust, well-researched business plan to potential lenders that outlines your vision, market analysis, and financial projections.

2. Networking: Establish connections within your industry or community that could lead to potential investment or loan opportunities.

3. Grants and Subsidies: Research government grants and financing options that may be available to startups in Denmark.

Work-Life Balance

Sole proprietors may find it challenging to maintain a healthy work-life balance due to the demands of running a business. Here are some strategies to consider:

1. Set Clear Boundaries: Define your working hours and stick to them to ensure time for personal activities.

2. Delegate or Outsource: If possible, delegate routine tasks or consider outsourcing functions like accounting or marketing to free up your time for strategic planning and self-care.

3. Utilize Technology: Use technology to automate tasks and streamline operations, allowing for more efficient management of your business.

Market Competition

Facing competition can be daunting for sole proprietors. To stay competitive, you can:

1. Innovate: Regularly assess and innovate your product or service offerings according to market demands.

2. Tailored Marketing Strategies: Develop targeted marketing strategies that focus on your unique value proposition that differentiates you from competitors.

3. Build Customer Relationships: Foster strong relationships with your customers through excellent service and engagement to build loyalty and repeat business.

Key Tax Obligations for Danish Sole Proprietors (VAT, Income Tax, AM-bidrag)

As a Danish sole proprietor, you are taxed personally on your business profits. This means your business income is added to your other personal income and taxed under the Danish personal tax system. To stay compliant and avoid penalties, you need to understand how VAT, income tax and the labour market contribution (AM-bidrag) work together.

Income tax on business profits

Your sole proprietorship does not pay corporate tax. Instead, the profit (revenue minus deductible expenses) is taxed as your personal income. You can normally choose between two main methods of taxation for business income:

• Personal income taxation (standard scheme) – business profit is included in your personal income and taxed together with salary and other income.
• Business tax scheme (virksomhedsordningen) – a special scheme that allows you to retain profits in the business at a flat rate and deduct interest more favourably, subject to specific rules and bookkeeping requirements.

Denmark has a progressive personal income tax system. In broad terms, your total income is subject to:

• Bottom-bracket state tax on personal income above a low threshold
• Top-bracket state tax on personal income above a higher threshold
• Municipal and church tax (rates vary by municipality, typically around 24–27% combined, plus optional church tax)
• Labour market contribution (AM-bidrag) at a flat 8% on most earned income, including business profits

The top-bracket state tax is charged only on the part of your personal income that exceeds a specific annual threshold. When you add AM-bidrag, municipal tax and state tax together, the maximum marginal tax rate on earned income is typically just under 53–56%, depending on your municipality and church tax.

You must report your expected business profit to the Danish Tax Agency (Skattestyrelsen) so that your preliminary tax (forskudsskat) can be adjusted. If your income changes significantly during the year, you should update your preliminary assessment to avoid large underpayments or overpayments.

AM-bidrag (Labour market contribution)

AM-bidrag is a mandatory contribution that finances the Danish labour market schemes. For sole proprietors, it is calculated as 8% of your business profit before personal income tax. In practice, the calculation works as follows:

1. Determine your taxable business profit (after deductible expenses).
2. Calculate 8% AM-bidrag on this amount.
3. Subtract AM-bidrag from the profit to arrive at your personal income base for further income tax.

AM-bidrag is not a separate social security system like in some other countries; it is an integrated part of the Danish tax system. It is, however, a separate line in your tax calculation and must be taken into account when planning your cash flow.

VAT (Moms) obligations

Whether you must register for VAT depends mainly on your annual turnover from VAT-liable activities. You are generally required to register for VAT if your expected turnover from taxable supplies in Denmark exceeds DKK 50,000 within any 12‑month period.

Key points about VAT for Danish sole proprietors:

• Standard VAT rate: 25% on most goods and services.
• Exempt activities: Certain sectors (e.g. most health services, education, some financial services and insurance) are exempt from VAT. If your main activity is VAT-exempt, you normally cannot charge VAT or deduct input VAT on your purchases.
• Voluntary registration: In some cases, you may voluntarily register for VAT even if your turnover is below DKK 50,000, for example to recover input VAT on start-up costs. This must be evaluated carefully, especially if you have both VAT-liable and VAT-exempt activities.

Once registered, you must:

• Charge 25% VAT on your invoices for VAT-liable goods and services
• Issue invoices that meet Danish VAT invoice requirements (including your CVR number, VAT amount and rate, invoice date and sequential invoice number)
• Keep proper records of all sales and purchases
• Submit VAT returns and pay VAT on time

The frequency of your VAT reporting depends on your annual turnover:

• Quarterly VAT reporting – common for many small businesses
• Half-yearly VAT reporting – possible for very small turnover
• Monthly VAT reporting – required for larger businesses above a certain turnover threshold

Each period has a fixed deadline for submitting the VAT return and paying any VAT due, usually one month and a few days after the end of the period. Late filing or late payment can result in interest and surcharges.

Advance tax payments and deadlines

As a sole proprietor, you pay tax on an ongoing basis through preliminary tax and, in some cases, voluntary on-account payments. The main elements are:

• Preliminary tax (forskudsskat): Based on your estimated annual income. You can and should update this estimate if your business results change.
• On-account tax payments (B‑skat): If you do not have salary income with withholding tax, you typically pay B‑skat in monthly instalments throughout the year.
• Residual tax (restskat): If your final tax is higher than what you have paid in advance, you must pay the difference. Early voluntary payments can reduce interest and surcharges.

It is important to monitor your profit during the year and adjust your preliminary tax if necessary. This helps you avoid large residual tax bills and ensures more accurate cash flow planning.

Deductible expenses and tax planning

Your taxable profit is your revenue minus deductible business expenses. Typical deductible costs include:

• Office rent and utilities for business premises
• Business-related telephone, internet and software subscriptions
• Professional fees (accounting, legal, consulting)
• Marketing and advertising costs
• Business travel and transport, subject to specific rules and documentation
• Depreciation on business assets such as equipment, computers and machinery

Private expenses are not deductible. If you use assets both privately and for business (for example, your car or home office), you must allocate costs between private and business use according to Danish tax rules.

Choosing the right taxation scheme (standard personal income vs. virksomhedsordningen), planning investments and timing of expenses can significantly affect your tax burden. Many sole proprietors benefit from professional advice to optimise their tax position within the Danish rules.

Consequences of non-compliance

Failure to meet your tax obligations can lead to:

• Interest and surcharges on late VAT and tax payments
• Estimated assessments by the tax authorities if you do not file returns
• Fines for missing or incorrect VAT registration
• In serious cases, criminal penalties for tax evasion

Keeping accurate records, filing returns on time and responding promptly to letters from Skattestyrelsen are essential parts of running a compliant Danish sole proprietorship. If you are unsure about your obligations, it is advisable to seek assistance from a Danish accountant or tax adviser familiar with the latest rules and thresholds.

Bookkeeping, Accounting and Record-Keeping Requirements

As a Danish sole proprietor, you are legally required to keep orderly and reliable accounts. Proper bookkeeping and record-keeping are not only a compliance obligation under the Danish Bookkeeping Act and Tax Control Act, but also the basis for correct VAT, income tax and AM-bidrag calculations. Even if your business is small, the authorities expect you to follow the same fundamental principles as larger companies.

Who must keep accounts and when

If you run a business as a sole proprietor in Denmark, you must keep business accounts from the moment you start your activity, regardless of whether you are VAT-registered or not. Once your taxable turnover exceeds the VAT registration threshold (currently DKK 50,000 within a 12‑month period), you must register for VAT and your bookkeeping must support correct VAT reporting on all sales and purchases.

Basic bookkeeping principles

Your bookkeeping must be complete, accurate and traceable. Every business transaction must be documented with a voucher (for example an invoice, receipt, bank statement or contract) and recorded in your accounting system. The records must show:

• All income from sales, fees, commissions and other business activities
• All business expenses, including purchases, rent, subscriptions, travel and other costs
• VAT on sales (output VAT) and on purchases (input VAT), where applicable
• Assets and liabilities, such as equipment, inventory, loans and tax payables

Entries must be made on an ongoing basis and as soon as reasonably possible after each transaction. You must be able to follow the trail from each entry back to the original document and from the document into the accounts (the so‑called audit trail).

Digital bookkeeping and approved systems

Danish rules increasingly favour digital bookkeeping. In practice, most sole proprietors are expected to use an electronic accounting system that can store data securely and provide an export of all records in a readable format for the tax authorities. The system should at minimum allow you to:

• Issue and store invoices and credit notes
• Record income and expenses with dates, amounts, VAT codes and counterparties
• Reconcile bank transactions with your accounting records
• Produce basic reports such as profit and loss, balance sheet and VAT statements

While spreadsheets can be used in very small setups, they must still meet all legal requirements for traceability, security and backup. In practice, using recognised Danish accounting software makes it easier to comply and to share data with your accountant and with Skattestyrelsen.

Retention periods and storage requirements

You must keep your accounting records for at least 5 full years after the end of the financial year they relate to. This retention period applies to:

• Invoices issued and received
• Receipts and expense documentation
• Bank statements and loan agreements
• Contracts with customers and suppliers
• Payroll records, if you have employees
• General ledger, journals and financial statements

Records may be stored electronically, but they must be readable, secure against loss and unauthorised changes, and accessible in Denmark upon request from the authorities. If you use cloud services, make sure you can export the data and that the provider meets Danish and EU data protection standards.

Separation of business and personal finances

Even though you and your sole proprietorship are legally the same person, you should clearly separate business and private finances in your bookkeeping. The most practical way is to use a dedicated business bank account and business payment cards. This makes it easier to:

• Document which expenses are business-related and deductible
• Avoid mixing private purchases with business costs
• Prepare reliable accounts and tax returns

Private withdrawals and deposits should be recorded as owner’s drawings or contributions, not as business income or expenses.

VAT bookkeeping and reporting

If you are VAT-registered, your bookkeeping must allow you to calculate VAT correctly for each reporting period. You must:

• Apply the correct VAT rate on sales (most goods and services at 25%)
• Record VAT separately from the net amount on invoices and in your accounts
• Distinguish between VAT-deductible and non-deductible expenses
• Keep documentation for any VAT-exempt or zero-rated sales

VAT must be reported and paid through TastSelv Erhverv according to your assigned reporting frequency (typically quarterly for smaller businesses, monthly for larger ones). Late or incorrect VAT reporting can lead to interest and penalties, so your accounting records must always be up to date at the end of each period.

Income tax, AM-bidrag and year-end accounts

Your bookkeeping forms the basis for your annual tax return and preliminary income assessment. At the end of each income year, you must prepare a statement of your business result showing:

• Total turnover
• Tax-deductible operating expenses
• Depreciation on assets such as equipment, vehicles and IT
• Net profit or loss

The net profit is used to calculate your personal income tax and labour market contribution (AM-bidrag at 8%). Even if you are not required to submit formal financial statements, your underlying accounts must be detailed enough to support all figures reported to Skattestyrelsen.

Cash, invoices and documentation standards

If you receive cash payments, you must record them daily and issue receipts or invoices. For all sales, your invoices must contain mandatory information such as:

• Your name and address
• Your CVR number if you are VAT-registered
• Invoice date and a unique, consecutive invoice number
• Description of goods or services supplied
• Quantity, unit price and total amount
• VAT rate and VAT amount, or a clear note if the sale is VAT-exempt

For expenses, you must keep original receipts or digital copies that clearly show supplier, date, amount, VAT and the nature of the purchase. Bank statements alone are not sufficient documentation for tax purposes.

Deadlines and ongoing obligations

Throughout the year, your bookkeeping must support several recurring deadlines, including:

• VAT reporting and payment according to your assigned frequency
• Payment of A-tax and AM-bidrag if you have employees
• Submission of your personal tax return with business income
• Any industry-specific reporting obligations, if applicable

Keeping your records updated monthly or at least quarterly helps you meet these deadlines and avoid last-minute errors.

Working with an accountant or bookkeeper

While you can legally handle your own bookkeeping as a sole proprietor, many business owners choose to work with a professional accountant or bookkeeper. A specialist familiar with Danish rules can help you:

• Set up a compliant chart of accounts and accounting system
• Ensure correct VAT treatment and deduction of expenses
• Prepare year-end accounts and tax calculations
• Respond to questions or audits from Skattestyrelsen

Even if you outsource, you remain legally responsible for the accuracy of your accounts. It is therefore important to understand the basic requirements and to provide your accountant with complete and timely documentation.

Choosing a Trade Name and Marketing Your Sole Proprietorship Legally

Choosing a trade name and marketing your Danish sole proprietorship is not only a branding decision – it also has legal and tax consequences. In Denmark, you can operate either under your personal name or under a registered business name, but you must comply with rules from the Danish Business Authority (Erhvervsstyrelsen), the Danish Tax Agency (Skattestyrelsen) and consumer protection and marketing legislation.

Using your personal name vs. registering a trade name

As a sole proprietor (enkeltmandsvirksomhed), you are allowed to run the business under your full personal name without registering a separate trade name. However, most entrepreneurs choose a distinctive business name for marketing and credibility reasons.

If you want to use anything other than your own full name, you must register the trade name when you register the business with the Danish Business Authority via Virk.dk. The registered name will appear in the CVR register and on your official documents.

Legal requirements for a Danish trade name

Your trade name must comply with the Danish Business Names Act and related practice. In particular, the name should:

• Clearly distinguish your business from existing registered names in the CVR register
• Not be misleading about the type, size or legal form of the business (for example, a sole proprietorship may not use “ApS” or “A/S” in the name)
• Not contain protected titles or words that you are not authorised to use (for example, “advokat”, “revisor” or regulated professional titles without the relevant licence)
• Not infringe existing trademarks or well-known brand names
• Not be offensive, discriminatory or contrary to public order

Before you decide, it is good practice to search the CVR register and the Danish Patent and Trademark Office database to check whether similar names or trademarks already exist. If you plan to build a strong brand, consider registering a trademark for your logo or name to obtain stronger protection than a simple trade name registration.

Information you must show in your business name

A Danish sole proprietorship does not have to include a specific legal suffix, but the public must be able to identify who is behind the business. In practice this means that:

• Your registered trade name and CVR number must be shown on invoices, contracts and other official documents
• Your website and online shop must clearly state the business name, CVR number, address and contact details
• If you use a brand name that differs from the registered trade name, the legal trade name and CVR number must still be visible in the footer, imprint or terms and conditions

Domain names, social media and online presence

When you choose a trade name, you should also check whether a suitable domain name and social media handles are available. In Denmark, .dk domains are administered by Punktum dk. The domain holder information is linked to your CPR or CVR number, so make sure it matches your registered business details.

Using a domain or social media name that is confusingly similar to an existing brand can lead to disputes or claims for infringement. Align your domain, trade name and trademark strategy from the start to avoid costly rebranding later.

Mandatory information in marketing and on your website

Danish law requires transparency in commercial communication. As a sole proprietor, you must ensure that customers can easily see who they are dealing with. On your website, order confirmations and marketing materials, you should include at least:

• Full trade name of the business
• CVR number
• Registered business address (not only a P.O. box)
• Email address and, where relevant, telephone number
• If you sell online to consumers, clear terms and conditions, including prices, delivery, right of withdrawal and complaint procedure

If you are VAT registered, your VAT number is the same as your CVR number, and it must appear on invoices and, in practice, is often shown in the website footer or imprint.

Marketing law: what you can and cannot do

All your marketing activities must comply with the Danish Marketing Practices Act and EU consumer protection rules. Some key principles are:

• Marketing must be clearly recognisable as advertising – it must not be disguised as neutral content
• Information about prices, discounts and “free” offers must be accurate and not misleading
• You must not use false claims, fake reviews or misleading comparisons with competitors
• Environmental and sustainability claims (for example “green”, “climate neutral”, “CO₂ neutral”) must be specific, documented and not exaggerated

If you target consumers, you must provide clear and understandable information before they make a purchase decision. This includes the total price including VAT and all mandatory fees, as well as any binding periods, subscription terms or automatic renewals.

Email marketing, SMS and newsletters

Sending electronic marketing in Denmark is strictly regulated. As a sole proprietor, you may not send unsolicited commercial emails, SMS or direct messages to individuals or businesses without prior consent, except in very narrow situations. In practice this means:

• You need explicit, informed consent before adding someone to your newsletter or sending promotional emails
• Consent must be voluntary, specific and documented – pre-ticked boxes are not valid
• Every marketing email or SMS must clearly identify you as the sender and include an easy, free way to unsubscribe
• You may only use the contact details for the purposes the person agreed to

There is a limited “existing customer” exception, but it has strict conditions and should be used carefully. For most small businesses, a clear opt-in process is the safest solution.

Social media and influencer marketing

If you use social media ads, collaborations or influencers, the same rules about recognisable advertising and non-misleading information apply. Sponsored posts, affiliate links and gifted products must be clearly marked as advertising. The responsibility is shared between you and the influencer, so you should provide written guidelines and keep documentation of the collaboration.

Use of price information and discounts

Price marketing is a frequent source of legal problems. Under Danish rules:

• All consumer prices must be shown including VAT and mandatory fees
• If you advertise a discount, the reference price must be real and documented – you may not use artificially high “before” prices
• Time-limited offers must actually be limited in time, and the end date must be clear
• “From” prices must not mislead customers about the typical price they will pay

For online shops, you must show the total price, including delivery and other unavoidable costs, before the customer completes the order.

SEO, content marketing and legal compliance

Search engine optimisation and content marketing are powerful tools for a Danish sole proprietorship, but they must remain honest and transparent. You may optimise your website for relevant keywords and create informative content, but you must not:

• Hide important information in small print or behind multiple clicks
• Use misleading meta titles or descriptions that do not match the actual content
• Copy competitors’ content or use protected material without permission

High-quality, accurate content that reflects your real services and prices is not only better for SEO but also reduces the risk of complaints and legal issues.

Using logos, images and third-party content

When you design your brand and marketing materials, respect copyright and trademark rules. You may not simply download images, fonts or logos from the internet and use them commercially without a licence. Instead, you should:

• Use your own photos or buy stock images with a commercial licence
• Check the licence terms for any icons, fonts or templates you use
• Obtain written permission before using customers’ logos or testimonials in your marketing

For testimonials and case studies, you must ensure that statements are true, not misleading and used with the customer’s consent, especially if they can be identified.

Balancing privacy and transparency

As a sole proprietor, your CPR number is tied to your business, but you should avoid publishing your CPR number in marketing or on your website. Use your CVR number for public identification and keep CPR-related information restricted to official registrations and secure communication with authorities and your accountant.

When you collect customer data for marketing purposes (for example newsletter sign-ups or contact forms), you must comply with GDPR. This includes informing users about what data you collect, why you collect it, how long you keep it and how they can exercise their rights. A clear privacy policy on your website is an important part of compliant marketing.

Practical steps to choose and market your trade name legally

1. Brainstorm a distinctive, descriptive name that fits your services and target audience
2. Check the CVR register and trademark databases for conflicting names or marks
3. Verify that a suitable domain name and key social media handles are available
4. Register your sole proprietorship and trade name with the Danish Business Authority
5. Consider trademark registration if you plan to build a strong, long-term brand
6. Set up your website, imprint and terms with all required legal information
7. Implement a compliant consent process for newsletters and other electronic marketing
8. Review your marketing messages, price information and campaigns against Danish marketing rules

A well-chosen, legally compliant trade name and a transparent marketing strategy help you build trust with Danish customers, avoid disputes and fines, and support the long-term growth of your sole proprietorship.

Using Your CPR Number vs. CVR Number: Privacy and Compliance Considerations

As a Danish sole proprietor, you will quickly encounter two key identifiers: your personal CPR number and your business CVR number. Understanding when to use each of them is essential for protecting your privacy, complying with Danish law and presenting a professional image to customers, suppliers and authorities.

CPR vs. CVR – what is the difference?

The CPR number is your personal civil registration number used for identification in the public system, taxation, health care and many private contracts. The CVR number is a business registration number issued by the Danish Business Authority (Erhvervsstyrelsen) when your sole proprietorship is registered in the Central Business Register (CVR).

As a sole proprietor, your business is not a separate legal entity from you personally, but for most external dealings you should use your CVR number, not your CPR number. The CVR number is public and is meant to be shared in a business context; the CPR number is sensitive personal data and is subject to strict protection rules.

When you must or should use your CVR number

Once your sole proprietorship is registered, you are generally expected to use your CVR number in all business-related documents and communication. This includes:

• Invoices and credit notes issued to customers
• Contracts and terms & conditions with clients and suppliers
• Quotes, order confirmations and delivery notes
• Business website, email signatures and marketing materials
• Registration for VAT (moms), payroll taxes and other taxes
• Reporting to SKAT (Danish Tax Agency) and Erhvervsstyrelsen
• Applications for licences, permits or industry registrations

Using your CVR number in these contexts is not only a legal expectation; it also signals that you operate a registered business, which can increase trust and make it easier for customers to verify your company in the CVR register.

When your CPR number is used in the business context

Even as a business owner, your CPR number remains primarily a private identifier. However, it is still used in several back-end processes:

• When you first register your sole proprietorship with Erhvervsstyrelsen
• For income tax assessment, as business profits are taxed as personal income
• For AM-bidrag (labour market contribution) and social security reporting
• When logging into public self-service systems (e.g. TastSelv Erhverv, Virk) via MitID
• In some banking procedures, such as opening a business account and KYC checks

These uses are typically between you and public authorities or financial institutions. They are covered by strict confidentiality rules and data protection requirements. You should not normally disclose your CPR number to customers or suppliers unless there is a very specific legal basis and a clear necessity.

Privacy and data protection considerations

Your CPR number is considered highly sensitive personal data under Danish data protection rules and the GDPR. Unnecessary sharing of your CPR number increases the risk of identity theft and misuse. As a sole proprietor, you should:

• Avoid printing your CPR number on invoices, contracts, websites or marketing materials
• Use your CVR number as the primary identifier in all business-facing documents
• Store any documents containing your CPR number securely and restrict access
• Use encrypted channels or secure portals when authorities or banks require CPR-based documentation
• Regularly review who has access to your CPR number within any systems or shared folders

If you process CPR numbers of others (for example, employees or certain clients), you must have a clear legal basis, inform the data subjects and implement appropriate technical and organisational security measures. In many cases, you will need a written data processing agreement with any external provider that handles such data on your behalf.

Legal obligations when using your CVR number publicly

Displaying your CVR number correctly is part of your legal compliance as a Danish business. You are generally required to ensure that:

• Your CVR number appears clearly on invoices and other accounting documents
• Your business name and CVR number are stated on your website and in your online shop, if you sell goods or services online
• Your CVR number is used when registering for VAT and other schemes with SKAT
• Your CVR number is included in formal correspondence with public authorities

Failure to use your CVR number where required can lead to practical problems, such as rejected invoices, delayed payments, difficulties with VAT deductions for your customers and potential issues in case of audits by the tax authorities.

Using CPR instead of CVR – typical risks and mistakes

Many new sole proprietors start out by issuing invoices or entering into contracts using only their personal details and CPR number. This can create several problems:

• Privacy risk: Your CPR number may circulate widely among customers, suppliers and accounting systems, increasing exposure to data breaches.
• Professional image: Customers may question whether your business is properly registered if they cannot find a CVR number.
• Accounting confusion: Mixing private and business identifiers can complicate bookkeeping, VAT reporting and tax audits.
• GDPR compliance issues: Unnecessary sharing of CPR numbers may be seen as a breach of data minimisation and security principles.

To avoid these issues, register for a CVR number as soon as your activity qualifies as a business and update all templates, contracts and communication to use the CVR number instead of the CPR number.

Online presence, e-commerce and invoicing platforms

If you run a website, online shop or use cloud-based invoicing and accounting tools, you should configure them to display your CVR number and business name consistently. This includes:

• Imprint or “about” pages on your website
• Checkout pages and order confirmations in your online shop
• Invoice templates in your accounting or invoicing software
• Payment links and payment service provider profiles

Most modern Danish and EU-compliant platforms are designed to work with CVR numbers. Avoid entering your CPR number into public-facing fields unless it is explicitly required and you understand the legal basis and security measures in place.

Bank accounts and separation of finances

While Danish law does not always mandate a separate business bank account for sole proprietors, opening one is strongly recommended. Use your CVR number when setting up the account and in all business-related transactions. This helps you:

• Separate private and business finances for clearer bookkeeping
• Reduce the need to share your CPR number with business partners
• Provide cleaner documentation in case of tax inspections or audits

Some banks will require both your CPR and CVR numbers for identification and compliance checks, but only the CVR number should appear on statements or payment details shared with customers and suppliers.

How to correct past misuse of your CPR number

If you have previously used your CPR number on invoices, contracts or your website, you can gradually correct this without disrupting your business:

1. Register your sole proprietorship and obtain a CVR number if you have not done so.
2. Update invoice templates, contracts, email signatures and your website to show your CVR number.
3. Inform regular customers and suppliers that your business is now identified by a CVR number and ask them to update their records.
4. Store old documents securely and avoid redistributing them if they contain your CPR number.
5. Review your data protection procedures to ensure that your CPR number is no longer shared unnecessarily.

Key takeaways for Danish sole proprietors

In practice, the rule of thumb is simple: your CPR number is for your private identity and dealings with authorities and your bank, while your CVR number is for your business identity and all external business communication. Using your CVR number consistently helps you comply with Danish legal requirements, protect your personal data and present a clear, trustworthy profile to customers and partners.

Hiring Employees as a Sole Proprietor: Labour Law and Payroll Duties

As your Danish sole proprietorship grows, you may reach a point where you need to hire employees. The moment you employ staff, you move into a more complex legal and administrative landscape governed by Danish labour law, tax rules and social security regulations. Understanding your obligations from the start helps you avoid fines, disputes and unexpected costs.

Registering as an employer and setting up payroll

Before you pay any salary, you must register as an employer with the Danish Business Authority (Erhvervsstyrelsen) and the Danish Tax Agency (Skattestyrelsen). If you already have a CVR number for your sole proprietorship, you add “employer” as an additional registration. Once registered, you are responsible for withholding and reporting:

• A-tax (withholding tax on salary)
• AM-bidrag (labour market contribution) at 8% of the employee’s gross salary before A-tax
• ATP (Arbejdsmarkedets Tillægspension – statutory labour market pension)

Most sole proprietors use an online payroll system integrated with eIncome (eIndkomst) to calculate and report these amounts. Salary, A-tax, AM-bidrag and ATP must be reported monthly to eIncome, typically by the 10th of the following month, and paid to Skattestyrelsen by the same deadline.

Employment contracts and working conditions

Danish law requires that employees receive written information about their employment terms. If an employee works an average of more than 3 hours per week over a 4-week period, you must provide a written employment contract or employment statement. This should include at least:

• Identity of employer and employee
• Workplace and job title or job description
• Start date and, if applicable, end date for fixed-term contracts
• Working hours (weekly hours and schedule framework)
• Salary, bonuses, benefits and payment dates
• Holiday entitlement and reference to the Danish Holiday Act or relevant collective agreement
• Notice periods and termination rules

Even if your business is not covered by a collective agreement (overenskomst), you must comply with mandatory rules on working time, rest periods, health and safety, non-discrimination and equal treatment. For full-time employees, the typical working week is up to 37 hours, and employees are entitled to daily and weekly rest periods under working time regulations.

Minimum wages and collective agreements

Denmark does not have a statutory national minimum wage. Instead, pay levels are largely determined by collective agreements between employers’ organisations and trade unions. As a sole proprietor, you are not automatically bound by a collective agreement, but you may:

• Choose to join an employers’ organisation and become covered by its agreements, or
• Sign a local agreement with a union or follow sector standards voluntarily

Even if you are outside collective agreements, you must pay a salary that is reasonable and in line with typical market levels for your industry and region to avoid disputes and reputational risk. If you employ foreign workers, you must also comply with rules on work permits, residence permits and minimum pay conditions where applicable.

Holiday, sickness and leave

The Danish Holiday Act (Ferieloven) gives employees the right to 25 days of paid holiday per year (equivalent to 5 weeks). Holiday is accrued at 2.08 days per month of employment and can generally be taken as it is earned (concurrent holiday). As an employer you must:

• Accrue and pay holiday allowance (feriepenge) at 12.5% of the employee’s holiday-qualifying salary, unless you pay full salary during holidays under a scheme equivalent to a collective agreement
• Report and pay holiday funds to the correct holiday scheme (e.g. FerieKonto or a recognised holiday fund) if you do not manage holiday pay yourself

For sickness, employees are normally entitled to salary during sickness according to the employment contract or collective agreement. If you pay salary during sickness, you may in many cases obtain reimbursement of statutory sickness benefits (sygedagpenge) from the municipality after a waiting period, provided you meet reporting deadlines and documentation requirements.

Employees are also protected by rules on maternity, paternity and parental leave. As a small employer, you may be entitled to partial reimbursement of salary paid during certain types of leave through public schemes, but only if you register and apply correctly and on time.

Mandatory social contributions and employer costs

In addition to gross salary, you must budget for a range of mandatory employer contributions. The exact amounts depend on your industry and whether you are covered by a collective agreement, but typical elements include:

• AM-bidrag: 8% of the employee’s gross salary, withheld from the employee but administered through your payroll
• ATP: A fixed contribution per month per employee; for full-time employees you pay the employer share while the employee pays a smaller share
• Industrial injury insurance: Mandatory workers’ compensation insurance (arbejdsskadeforsikring) for all employees
• Occupational health contributions: Contributions to e.g. Arbejdsmarkedets Erhvervssikring and other statutory schemes, typically billed annually

If you choose to offer a company pension scheme, you will usually pay an employer contribution (for example 8–12% of salary) on top of the employee’s own contribution. In some sectors, pension contributions are mandatory under collective agreements or standard contracts.

Work environment and health & safety

As soon as you have employees, you are responsible for ensuring a safe and healthy work environment under the Danish Working Environment Act (Arbejdsmiljøloven). This includes:

• Assessing and managing physical and psychological risks at the workplace
• Providing necessary equipment, protective gear and training
• Ensuring proper ergonomics, ventilation, lighting and fire safety
• Preventing stress, harassment and bullying

Depending on your size and risk profile, you may need to establish a formal health and safety organisation and prepare a written workplace assessment (APV). The Danish Working Environment Authority (Arbejdstilsynet) can inspect your business and issue orders or fines if you do not comply.

Handling tax, payslips and reporting

Every time you pay salary, you must:

1. Calculate gross salary, AM-bidrag, A-tax, ATP and any pension contributions
2. Withhold AM-bidrag (8%) and A-tax based on the employee’s tax card (skattekort)
3. Issue a payslip showing all components of pay and deductions
4. Report salary and contributions to eIncome (eIndkomst) by the monthly deadline
5. Pay the withheld amounts to Skattestyrelsen and relevant funds on time

Failure to report or pay correctly can lead to interest, surcharges and penalties. Using a certified payroll system or working with a professional accountant significantly reduces the risk of errors.

Hiring your first employee: practical steps

When you are ready to hire, a simple checklist can help you stay compliant:

• Register as an employer and update your business registration
• Take out mandatory industrial injury insurance and any required supplementary insurance
• Prepare a clear written employment contract tailored to the role
• Choose and set up a payroll system integrated with eIncome
• Collect the employee’s CPR number and tax card details
• Register for ATP and any pension scheme you will offer
• Set up procedures for holiday, sickness reporting and leave
• Ensure your workplace meets health and safety requirements

Although hiring employees as a sole proprietor in Denmark adds administrative work and legal responsibilities, it also allows you to grow your business and take on more clients. With proper planning, robust payroll routines and support from a knowledgeable accountant, you can manage your employer obligations efficiently and focus on developing your company.

Social Security, Pension and Holiday Pay Implications for Sole Proprietors

When you run a sole proprietorship (enkeltmandsvirksomhed) in Denmark, you are not automatically covered by the same social security, pension and holiday pay rules as ordinary employees. Instead, you are treated as self-employed, and you must actively decide how to secure yourself against illness, loss of income and retirement, and how to handle your own holidays.

Social security for Danish sole proprietors

As a sole proprietor, you are generally covered by the Danish public welfare system on the same basic terms as other residents. This includes access to the public healthcare system, child benefits and certain social benefits, as long as you are tax resident and pay tax in Denmark.

However, there are important differences compared to employees:

• Unemployment benefits (A-kasse): You are not automatically entitled to unemployment benefits. To receive dagpenge if your business closes or your income drops, you must be a member of an unemployment insurance fund (A-kasse) that accepts self-employed persons, pay monthly contributions and meet their income and membership requirements.
• Sickness benefits (sygedagpenge): As a self-employed person, you can receive sickness benefits from your municipality, but the waiting period is longer than for employees. You normally qualify after a certain number of weeks of documented illness and sufficient prior income from self-employment. You can purchase voluntary insurance with Udbetaling Danmark to shorten the waiting period and secure higher coverage.
• Maternity and paternity benefits: You can receive parental benefits (barselsdagpenge) if you meet the income and working-hour conditions as a self-employed person. You must document that you have worked a minimum number of hours and earned a minimum income from your business in the reference period before the leave.
• Work injury insurance: You are not automatically covered by the statutory workers’ compensation scheme that applies to employees. If you want cover for work-related injuries to yourself as the owner, you must take out a voluntary work injury insurance policy as a self-employed person.

In addition, you must pay the Danish labour market contribution (AM-bidrag) of 8% on your business income before personal income tax is calculated. This contribution helps finance the Danish social security system but does not replace private insurance or pension savings.

Pension options for sole proprietors

As a sole proprietor, you do not receive employer-funded pension contributions. Your future retirement income will typically consist of:

• Public old-age pension (folkepension), including basic amount and any pension supplement, depending on your total income at retirement
• ATP (Arbejdsmarkedets Tillægspension), if you have previously been employed or make voluntary ATP contributions as self-employed
• Any private or occupational pension schemes you establish and fund yourself

To build sufficient pension savings, many sole proprietors choose one or more of the following:

• Private pension schemes with tax deduction, such as rate pension (installment pension) or life annuity (livrente), where contributions are generally deductible in your personal income up to specific annual limits set by Danish tax law.
• Capital pension–type savings (e.g. aldersopsparing), where contributions are not deductible, but payouts are typically tax-advantaged compared to ordinary savings.
• Ordinary long-term investments through investment accounts, equity portfolios or real estate, which are taxed under the normal capital income or share income rules.

Because pension contributions can significantly reduce your taxable income, it is often beneficial to coordinate pension planning with your accountant. The optimal contribution level depends on your expected annual profit, your marginal tax rate and whether you use schemes such as business taxation (virksomhedsordningen) or capital return scheme (kapitalafkastordningen).

Holiday pay and time off as a sole proprietor

Danish holiday legislation (ferieloven) is primarily designed to protect employees. As the owner of a sole proprietorship, you are not considered an employee in your own business, so you do not earn statutory holiday pay (feriepenge) from your own work and you are not entitled to paid holidays from your company.

This has several practical consequences:

• You do not receive holiday pay from your own business when you take time off.
• You must finance your holidays directly from your business profits or personal savings.
• You are not required to report your own holidays to any holiday fund or authority.

If you have employees, they are covered by the Danish Holiday Act and any applicable collective agreements. In that case, you must:

• Accrue and pay holiday pay for your employees, typically 12.5% of their qualifying salary, unless a collective agreement specifies another arrangement.
• Report and pay holiday pay to the relevant holiday scheme (e.g. FerieKonto or a private holiday fund) within the statutory deadlines.
• Ensure that employees can take their accrued holiday within the current holiday year and any permitted carry-over period.

For yourself as the owner, it is wise to plan holidays in your cash flow and pricing. Many sole proprietors calculate their annual income target by including the weeks they expect to be on holiday without income, so that the remaining working weeks generate enough profit to cover both living costs and time off.

Practical steps to protect yourself

To secure your social and financial position as a Danish sole proprietor, consider the following actions:

• Assess whether to join an A-kasse that covers self-employed persons to protect against loss of income if you close or pause your business.
• Review voluntary sickness insurance options to reduce the waiting period for public sickness benefits and ensure a realistic compensation level.
• Establish a structured pension plan with regular contributions, taking advantage of tax-deductible schemes where appropriate.
• Build a liquidity buffer to cover periods without income, such as holidays, illness or seasonal downturns.
• If you employ staff, implement correct procedures for holiday pay, social contributions and work injury insurance from day one.

By actively managing social security, pension and holiday pay, you reduce personal financial risk and create a more sustainable foundation for your Danish sole proprietorship in the long term.

Handling Invoices, Payment Terms and Debt Collection Under Danish Law

As a Danish sole proprietor, you are legally responsible for issuing correct invoices, agreeing clear payment terms and handling late payments in line with Danish law. Proper invoicing and debt collection are not only compliance issues – they also protect your cash flow and reduce the risk of disputes with customers and SKAT.

Mandatory information on Danish invoices

Danish law requires that invoices contain specific information so they can be used for bookkeeping, VAT reporting and potential audits. Whether you invoice private consumers or businesses, each invoice should at minimum include:

• Your full name or business name and address
• Your CVR number (or CPR number if you operate without CVR, though using CVR is strongly recommended)
• Customer’s name and address (and CVR number if it is a business customer)
• Unique, consecutive invoice number
• Invoice date (issue date)
• Clear description of the goods or services supplied
• Quantity and unit price
• Delivery date or period, if different from the invoice date
• Net amount excluding VAT
• Applicable VAT rate (normally 25% in Denmark) and VAT amount
• Total amount including VAT
• Payment terms and due date

If you are VAT-registered, you must show VAT separately and ensure that the VAT rate and amount are clearly identifiable. If a specific supply is VAT-exempt (for example certain financial services, health services or education), you should state the legal basis or a short note such as “VAT exempt under Danish VAT Act”.

Electronic invoicing and e-invoices to public authorities

When you sell to Danish public authorities (state, regions, municipalities and many public institutions), you must issue electronic invoices in the OIOUBL or Peppol format. Paper or PDF invoices sent by email are not sufficient for these customers. You will typically need:

• Your own CVR number
• The public customer’s EAN/GLN number
• Reference information required by the authority (for example order number or contact person)

Most accounting and invoicing systems in Denmark can generate compliant e-invoices and send them via NemHandel or Peppol. For private customers and private businesses, PDF or system-generated electronic invoices are generally acceptable, as long as they contain all mandatory information and can be stored securely for accounting purposes.

Standard payment terms in Denmark

Danish law allows you to agree payment terms freely, as long as they are not unfair to the other party. Common practice for business customers is 8, 14 or 30 days from invoice date. For private consumers, immediate payment or short terms (for example 8 days) are typical.

To avoid disputes, always state your payment terms clearly on the invoice, including:

• Due date (for example “Payment due: 30 days from invoice date”)
• Accepted payment methods (bank transfer, MobilePay, card, etc.)
• Your bank account details (reg. nr. and account number or IBAN/BIC for international payments)
• Any late payment interest and reminder fees you intend to charge

Charging interest on late payments

If a customer pays late, you may charge interest on the overdue amount. Under Danish rules, the default statutory interest rate for commercial claims is the Danish National Bank’s official lending rate plus 8 percentage points per year, calculated as simple interest. You can agree a different rate in your contract or general terms, but it must be clearly communicated to the customer in advance and must not be unreasonable.

Interest is normally calculated from the day after the due date until the day payment is received. For consumer customers, you should ensure that your interest terms are transparent and in line with consumer protection rules. Many sole proprietors choose to refer to “statutory interest” on invoices and in terms and conditions to keep things simple and compliant.

Reminder fees and compensation for collection costs

In addition to interest, you may charge certain reminder and collection fees if a customer does not pay on time. For business-to-business invoices, you are generally allowed to:

• Charge a fixed compensation fee of 310 DKK once per overdue invoice when the claim becomes overdue
• Charge reasonable reminder fees for written reminders, provided the fees and reminder procedure are clearly stated in your terms

For consumers, the rules are stricter. Reminder fees must be reasonable and clearly communicated in advance, and you must follow the consumer credit and debt collection rules. Excessive or unexpected fees can be considered unfair and may not be enforceable.

Practical reminder procedure

A simple, legally sound reminder process for a sole proprietor might look like this:

1. Invoice issued with clear due date and payment terms.
2. Short, friendly reminder by email or phone a few days after the due date, without fees.
3. First written reminder with a modest reminder fee and updated due date.
4. Second written reminder, stating that the claim will be handed over to a debt collection agency or lawyer if payment is not received by a specific date.
5. Transfer of the claim to a debt collection agency, lawyer or initiation of legal collection through the Danish courts (for example via the small claims procedure).

Keep all communication polite, factual and documented. This helps if the case later ends up with a collection agency, in court or under review by the Danish Consumer Ombudsman.

Using debt collection agencies and legal collection

You are allowed to use authorised debt collection agencies or lawyers to collect overdue invoices. They must follow the Danish Debt Collection Act, which sets limits on how debtors may be contacted and what fees can be charged. As a sole proprietor, you should:

• Choose agencies or advisors that are familiar with Danish rules and consumer protection requirements
• Ensure that any additional fees charged to the debtor are lawful and clearly based on the rules for collection costs
• Continue to record the outstanding amount, interest and fees correctly in your accounts

For undisputed claims, you can also use the simplified court procedures for debt collection. This can be cost-effective for larger claims but requires accurate documentation of the invoice, reminders and any agreements with the customer.

Bookkeeping and documentation requirements

Danish bookkeeping rules require you to keep copies of all invoices, credit notes, reminders and related correspondence for at least five years. This applies whether the documents are in paper or electronic form. Your records must allow SKAT and other authorities to see:

• When and to whom you issued invoices
• What you sold and at what price
• How VAT was calculated
• When and how payments were received
• How you calculated interest and fees on late payments

Using a Danish-compliant accounting system makes it easier to meet these requirements, generate correct VAT reports and provide documentation quickly in case of an audit.

Consumer protection and fair practices

If you sell to private consumers, you must comply with Danish consumer law, including rules on unfair contract terms, information duties, cooling-off periods for distance sales and complaint handling. In practice, this means you should:

• Provide clear information about prices, VAT, fees and payment terms before the customer commits
• Avoid hidden charges or complex fee structures
• Respect statutory cancellation rights where applicable (for example online sales to consumers)
• Handle complaints and disputes in a transparent and timely way

Unfair or unclear invoicing and collection practices can lead to complaints to the Consumer Ombudsman and damage your reputation, even if the amounts involved are small.

Cross-border invoicing considerations

If you invoice customers in other EU countries or outside the EU, additional VAT and invoicing rules may apply. For example, business-to-business services within the EU often fall under the reverse charge mechanism, where you issue an invoice without Danish VAT and state that the customer accounts for VAT in their own country. In such cases, you should:

• Verify the customer’s VAT number via the EU VIES system
• State both your VAT number and the customer’s VAT number on the invoice
• Add a note indicating that VAT is reverse charged under EU rules

For sales to private consumers in other EU countries, distance selling and OSS (One Stop Shop) rules may affect where VAT is due and what must appear on your invoices. It is important to align your invoicing and payment terms with your cross-border VAT setup.

Integrating invoicing and debt collection into your business routines

To stay compliant and protect your cash flow, build clear routines around invoicing and payment follow-up:

• Issue invoices promptly after delivery of goods or services
• Use consistent invoice numbering and store all documents securely
• Monitor due dates and follow up systematically on late payments
• Update your general terms and conditions so they reflect your interest rates, reminder fees and collection procedures
• Coordinate with your accountant or bookkeeper to ensure that interest, fees and bad debts are recorded correctly for tax and VAT purposes

Well-structured invoicing and debt collection processes help you comply with Danish law, reduce administrative stress and create a more professional impression with your customers.

Data Protection (GDPR) Obligations for Small Service-Based Sole Proprietors

Even as a small, service-based sole proprietor in Denmark, you are very likely subject to the EU General Data Protection Regulation (GDPR) and the Danish Data Protection Act. If you process any information that can identify a person – for example client names, emails, invoices with CPR numbers, CVs, or health-related details – you must comply with these rules. Below you will find the key obligations that typically apply to small Danish businesses such as consultants, therapists, IT freelancers, bookkeepers, designers and other service providers.

When does GDPR apply to a Danish sole proprietor?

GDPR applies whenever you process personal data in a structured way for business purposes. This includes:

• Client contact details stored in email, a CRM system or on your phone
• Invoices and contracts containing names, addresses, bank details or CPR numbers
• Newsletters and marketing lists with email addresses
• Employee data if you hire staff (salaries, CPR, tax information)
• Special categories of data, such as health information, religious beliefs or trade union membership, if relevant to your services

Purely personal or household activities are excluded, but almost all commercial activities fall under GDPR, even if you are a one-person business with very few clients.

Your role as data controller

As a sole proprietor you are usually the data controller. This means you decide why and how personal data is processed and you are legally responsible for compliance. If you use external providers – for example cloud accounting software, newsletter tools, web hosting or payroll services – they are typically data processors acting on your behalf.

As a controller you must:

• Have a clear and lawful purpose for each type of data you collect
• Collect only the data you actually need (data minimisation)
• Keep data accurate and up to date
• Store data securely and limit access
• Delete or anonymise data when you no longer need it

Lawful basis for processing client data

Under GDPR you must always have a lawful basis for processing personal data. For small service-based businesses in Denmark, the most common bases are:

• Contract – when you process data to provide your services, prepare an offer, issue invoices or manage ongoing client relationships.
• Legal obligation – when you keep accounting records, invoices and payroll documentation to comply with Danish bookkeeping and tax rules.
• Legitimate interest – for example limited, targeted B2B marketing to existing or potential business clients, provided you respect marketing rules and allow easy opt-out.
• Consent – for activities that are not strictly necessary for the contract, such as sending newsletters to private individuals or using certain cookies for marketing purposes.

Consent must be freely given, specific, informed and unambiguous. Pre-ticked boxes or bundled consents are not valid. You must be able to document that you obtained consent and allow people to withdraw it easily.

Information you must give to clients (privacy notice)

GDPR requires you to inform individuals about how you use their data. The easiest way is to create a clear, accessible privacy notice on your website and refer to it in your contracts, emails or booking confirmations. Your privacy notice should typically include:

• Your business name, address and contact details (and CVR number if applicable)
• What types of personal data you collect (e.g. contact details, payment information, service history)
• For what purposes and on what lawful bases you process the data
• How long you keep different categories of data (for example, accounting records kept for at least 5 years under Danish bookkeeping rules)
• Who you share data with, such as your accountant, IT providers or public authorities
• Whether data is transferred outside the EU/EEA and on what legal basis
• The rights of the data subject and how they can contact you to exercise them
• How to complain to the Danish Data Protection Agency (Datatilsynet)

Data subject rights you must respect

Individuals whose data you process (clients, leads, employees, suppliers) have specific rights under GDPR. As a sole proprietor you must have simple procedures to handle:

• Right of access – they can ask for a copy of their personal data and information about how you process it.
• Right to rectification – they can ask you to correct inaccurate or incomplete data.
• Right to erasure – in some cases they can ask you to delete data, for example when it is no longer needed. You may keep data that you must retain by law, such as accounting records.
• Right to restriction – they can ask you to limit processing in certain situations.
• Right to object – they can object to processing based on legitimate interests, including direct marketing.
• Right to data portability – for data processed by automated means based on consent or contract, they can request a copy in a structured, commonly used format.

You must respond to requests without undue delay and generally within one month. In complex cases you may extend this by two further months, but you must inform the person about the delay and the reasons.

Data processing agreements with your suppliers

If you use external providers that process personal data on your behalf, Danish and EU law require you to sign a written data processing agreement (DPA) with each of them. This typically applies to:

• Cloud accounting and invoicing systems
• CRM and email marketing platforms
• Online booking systems
• IT support and hosting providers
• Payroll and HR service providers

The agreement must specify, among other things, the subject and duration of processing, the nature and purpose of the processing, the types of personal data, categories of data subjects, and the security measures used. Many reputable software providers already offer standard DPAs that meet GDPR requirements.

Transferring data outside the EU/EEA

If you use tools or cloud services that store or access data from outside the EU/EEA – for example US-based providers – you must ensure there is a valid legal mechanism for the transfer. Depending on the country, this may involve:

• An adequacy decision from the European Commission
• Standard Contractual Clauses (SCCs) combined with a transfer risk assessment
• Other safeguards recognised by GDPR

You should know where your main systems store data and document the legal basis for any international transfers in your records and privacy notice.

Security measures appropriate for small businesses

GDPR does not require you to implement expensive enterprise-level security, but you must take “appropriate technical and organisational measures” to protect personal data. For a small Danish sole proprietor this usually includes:

• Using strong, unique passwords and enabling two-factor authentication where possible
• Encrypting laptops, phones and external drives that store client data
• Regularly updating software and using reputable antivirus and firewall solutions
• Limiting access to data to only what is necessary for your work
• Backing up important data securely and testing restore procedures
• Locking physical files in cabinets and controlling access to your office

You should document your main security measures in a simple internal policy so you can demonstrate compliance if Datatilsynet asks.

Data breaches: what you must do

A personal data breach is any security incident that leads to accidental or unlawful destruction, loss, alteration, unauthorised disclosure of, or access to personal data. Examples include sending an email with sensitive information to the wrong recipient, losing an unencrypted laptop, or your systems being hit by ransomware.

If a breach occurs, you must:

• Document what happened, which data was affected and what you did to limit the damage
• Assess the risk to the rights and freedoms of the affected individuals
• Notify Datatilsynet without undue delay and, where feasible, within 72 hours if the breach is likely to result in a risk to individuals
• Inform the affected individuals if the risk is high, explaining what happened and what they can do to protect themselves

Record-keeping and documentation duties

Even as a small business, you must be able to demonstrate that you comply with GDPR. This principle of “accountability” means you should keep basic documentation, such as:

• A simple overview of what personal data you process, for what purposes and on what legal bases
• Copies of your privacy notice and any consent forms
• Data processing agreements with your main suppliers
• Internal guidelines on data retention and security
• Records of any data breaches and how you handled them

Some very small businesses with low-risk processing may have reduced formal obligations, but in practice it is advisable for all Danish sole proprietors to maintain at least minimal records. This also helps you manage risk and respond quickly to client questions.

Marketing, cookies and electronic communications

If you use personal data for marketing, you must comply with both GDPR and Danish marketing and cookie rules. Key points include:

• For email marketing to private individuals, you generally need prior consent, unless you meet the strict conditions for the “existing customer” exception.
• For B2B marketing, you may rely on legitimate interest in some cases, but you must respect opt-outs and avoid intrusive or misleading practices.
• If your website uses cookies or similar technologies that are not strictly necessary (for example analytics or marketing cookies), you must obtain valid consent and provide clear information through a cookie banner and policy.

Do you need a Data Protection Officer (DPO)?

Most small Danish sole proprietors do not need to appoint a Data Protection Officer. This obligation usually applies only to public authorities or businesses that carry out large-scale systematic monitoring or process large volumes of sensitive data. However, you should still designate who is responsible for data protection in your business – in a one-person company this will simply be you.

Consequences of non-compliance

Non-compliance with GDPR and the Danish Data Protection Act can lead to investigations by Datatilsynet, orders to change your practices, temporary bans on processing and, in serious cases, administrative fines. For small businesses, the more immediate risk is reputational damage and loss of client trust if personal data is mishandled.

By putting in place clear privacy information, basic security measures, simple internal routines and proper agreements with your suppliers, you can meet your GDPR obligations in a practical way that supports – rather than hinders – the growth of your Danish sole proprietorship.

Industry-Specific Licences and Authorisations Commonly Required in Denmark

Many Danish sole proprietors can operate with only a CVR registration and standard tax compliance. However, a wide range of trades and professions require additional licences, approvals or notifications before you start trading. Failing to obtain the right authorisations can lead to fines, forced closure of your business and, in serious cases, criminal liability. This overview highlights the most common industry-specific requirements relevant to small businesses and freelancers in Denmark.

How industry-specific licences work in Denmark

Licences and authorisations are typically issued by sector authorities such as the Danish Business Authority (Erhvervsstyrelsen), the Danish Safety Technology Authority (Sikkerhedsstyrelsen), the Danish Veterinary and Food Administration (Fødevarestyrelsen), the Danish Transport Authority (Trafikstyrelsen) and local municipalities. In many cases, you must:

• Register your sole proprietorship and obtain a CVR number
• Meet education, experience or “fit and proper” requirements
• Comply with technical standards, safety rules or professional codes
• Pay a fee and renew the licence periodically

Below are the sectors where Danish sole proprietors most frequently need special permissions.

Food, cafés, catering and alcohol

If your business handles food or drink in Denmark, you will usually need approval or registration with the Danish Veterinary and Food Administration. This applies to restaurants, cafés, food trucks, bakeries, catering, online food delivery and many small-scale producers.

Key points include:

• Food business registration/approval: Most food businesses must be registered before opening. Some higher‑risk activities (for example meat processing) require prior approval and inspection.
• Smiley scheme: Once inspected, your business receives a “smiley” report that must be displayed physically and is published online.
• Alcohol licences: Serving strong alcohol on premises generally requires a municipal alcohol licence. Requirements differ between municipalities and may include opening hours, serving rules and security measures.
• Home‑based food production: Even small home kitchens selling to the public often need registration and must follow hygiene rules, traceability requirements and labelling standards.

Construction, electrical, plumbing and technical trades

Many building and installation activities can only be carried out by businesses with specific authorisations, even if you are a one‑person sole proprietorship.

• Electrical installations: Permanent electrical work on installations connected to the grid generally requires authorisation from the Danish Safety Technology Authority. The business must have a technically responsible person with approved qualifications.
• Gas, water and heating installations: Work on gas installations, pressurised systems and certain plumbing and heating systems is also regulated and requires authorisation.
• Construction and structural work: Larger building projects require building permits from the municipality. As a contractor, you must follow the Danish Building Regulations (BR) and, where relevant, occupational health and safety rules set by the Danish Working Environment Authority.
• Scaffolding, demolition and asbestos: Certain high‑risk activities require special training certificates and, in some cases, prior notification to the authorities.

If you advertise yourself as an authorised installer or contractor, your authorisation must be valid and correctly registered under your CVR number.

Transport, taxis, goods and passenger services

Transport is one of the most regulated areas for small businesses in Denmark. Depending on your activity, you may need permits from the Danish Transport Authority or your municipality.

• Taxi and limousine services: Operating a taxi or similar service requires a taxi licence. You must meet requirements on vehicle standards, insurance, driver qualifications and often local rules on fares and dispatch systems.
• Commercial goods transport: Transporting goods for others for payment in vehicles above certain weight thresholds typically requires a goods transport licence and compliance with EU driving and rest time rules.
• Bus and passenger transport: Carrying passengers in larger vehicles requires specific passenger transport licences, safety checks and driver qualifications.

Even if you only drive part‑time as a sole proprietor, you must ensure you have the correct transport authorisation for your service model.

Healthcare, wellness and personal care

Healthcare and many wellness services are subject to strict professional and advertising rules in Denmark.

• Authorised healthcare professions: Doctors, nurses, dentists, chiropractors and several other professions must be authorised by the Danish Patient Safety Authority. If you run a clinic as a sole proprietor, both you and your clinic may need registration.
• Alternative therapists: Some complementary therapies can be practised without formal authorisation, but you must follow consumer protection rules and may be restricted in how you describe treatments and health effects.
• Cosmetic treatments: Procedures such as botox, fillers and certain laser treatments are heavily regulated and often require a medical professional and clinic approval.
• Hairdressers, tattoo and piercing studios: These businesses must comply with hygiene, safety and, for tattooing, registration requirements. Municipal rules and inspections are common.

Financial, legal and real estate services

Advisers who handle client money, investments or legal matters often need special registrations and must follow anti‑money‑laundering (AML) rules.

• Accountants and bookkeepers: Providing statutory audit services requires approval as a state‑authorised or registered public accountant. Non‑audit bookkeeping and accounting services are less strictly regulated but are still covered by AML rules when you advise on tax or finances.
• Financial advisers and investment services: Offering investment advice, portfolio management or payment services may require authorisation or registration with the Danish Financial Supervisory Authority (Finanstilsynet).
• Real estate agents: Real estate brokerage is regulated and normally requires specific education, registration and adherence to professional conduct rules.
• Lawyers and legal services: Only admitted lawyers (advokater) may use the protected title and perform certain reserved legal activities. Law practices must be organised and insured according to bar rules.

Retail, e‑commerce and second‑hand goods

Most general retail and online shops can operate with standard business registration, but there are important exceptions.

• Pharmaceuticals and medical devices: Selling medicines, certain supplements or medical devices is highly regulated and may require pharmacy status or specific authorisations.
• Tobacco, e‑cigarettes and nicotine products: Retailers must follow strict rules on registration, age verification, product display and marketing.
• Alcohol retail: Selling alcohol for off‑premises consumption is subject to age limits, labelling and, in some cases, local rules.
• Second‑hand and pawn activities: Buying and selling used goods, precious metals or operating as a pawnbroker can trigger registration and AML obligations, including customer identification and record‑keeping.

Education, childcare and social services

If your sole proprietorship works with children, young people or vulnerable adults, you may face additional approval and background check requirements.

• Private childcare and after‑school care: Childminders and similar services often need municipal approval, safety checks of premises and child protection procedures.
• Private schools and training centres: Operating an educational institution can require approval from the Ministry of Children and Education or other authorities, depending on the type of education and funding.
• Social and care services: Services for the elderly, disabled or other vulnerable groups may require authorisation, quality standards and supervision.

Creative industries, events and entertainment

Many creative and cultural activities are lightly regulated, but certain event‑based businesses still need permissions.

• Public events and festivals: Larger events often require municipal permits covering crowd safety, fire safety, temporary structures, food stalls and noise limits.
• Music venues and nightlife: Bars, clubs and music venues need appropriate alcohol licences, may face noise regulations and must comply with security and opening‑hours rules.
• Film, drones and photography: Commercial drone use is regulated and may require registration, pilot training and operational authorisation, especially in urban areas or near airports.

Environmental, waste and hazardous materials

Businesses that generate, transport or treat waste or use hazardous substances must follow environmental rules and, in some cases, obtain permits.

• Waste collection and recycling: Commercial waste operators often need municipal approval and must comply with sorting and reporting obligations.
• Hazardous waste and chemicals: Handling, storing or transporting hazardous materials can require specific permits, safety documentation and staff training.
• Noise, emissions and discharges: Workshops, garages and small manufacturing sites may need environmental permits or to comply with local zoning and noise limits.

How to check if your sole proprietorship needs a licence

Before you start trading, you should:

1. Describe your planned activities in detail, including where and how you will operate
2. Check guidance from the Danish Business Authority and relevant sector authorities
3. Contact your municipality for local permit and zoning requirements
4. Review professional association rules if you belong to a regulated profession

Licensing rules can change, and new categories of businesses are regularly brought under regulation, especially in areas such as financial services, transport and health‑related activities. Keeping your authorisations up to date and correctly linked to your CVR number is an essential part of running a compliant Danish sole proprietorship.

Cross-Border Activities: Selling to EU and Non-EU Customers as a Danish Sole Proprietor

Many Danish sole proprietors sell digital services, consulting or physical goods to customers abroad. Cross-border activities can be profitable, but they also trigger specific VAT, invoicing and documentation rules. Understanding the difference between EU and non-EU sales is essential to stay compliant and avoid unexpected tax bills or penalties.

Selling to private customers (B2C) in other EU countries

If you sell to private consumers in other EU countries, the main rule is that Danish VAT applies until your total cross-border B2C sales of goods and certain services to all EU countries combined exceed the EU-wide distance selling threshold of EUR 10,000 (excluding VAT) per calendar year. Below this threshold, you normally charge Danish VAT on your invoices and report it in your Danish VAT return.

Once your total B2C sales to other EU countries exceed EUR 10,000 in a year, you must charge VAT in the customer’s country instead of Danish VAT for:

• Distance sales of goods to private customers in the EU
• Telecommunications, broadcasting and electronic services (TBE)
• Some other services where the place of supply is the customer’s country

To handle this, you can register for the One Stop Shop (OSS) scheme in Denmark. With OSS, you file a quarterly electronic VAT return with the Danish Tax Agency (Skattestyrelsen), reporting the VAT due in each customer’s EU country. Skattestyrelsen then transfers the VAT to the relevant tax authorities abroad. OSS simplifies compliance because you avoid separate VAT registrations in each EU country.

For B2C sales, you must clearly show on the invoice which VAT rate you have applied (Danish or foreign) and keep records that prove where your customer is located, such as billing address or IP address for digital services.

Selling to business customers (B2B) in the EU

When you sell to VAT-registered businesses in other EU countries, the reverse charge mechanism usually applies for services and many types of goods. In practice, this means:

• You do not charge Danish VAT on the invoice
• You state the customer’s valid VAT number and your own Danish VAT number (CVR)
• You add a note such as “Reverse charge – VAT to be accounted for by the recipient”

For most cross-border B2B services within the EU, the place of supply is the customer’s country. The customer accounts for VAT in their own VAT return under the reverse charge rules. For intra-EU supplies of goods, you can normally invoice with 0% Danish VAT if the goods are transported to another EU country and the customer has a valid VAT number there. These supplies must be reported in your Danish VAT return and in the EU sales listing (EC Sales List).

Always verify your customer’s VAT number via the EU’s VIES system and keep documentation of transport and delivery to support the 0% VAT treatment in case of a tax audit.

Selling to customers outside the EU (exports)

Sales of goods from Denmark to customers outside the EU are generally treated as exports with 0% Danish VAT, provided that the goods physically leave the EU and you keep proper export documentation (customs declarations, transport documents, proof of delivery). Even though you do not charge Danish VAT, you must still report these sales in your VAT return as exports.

For services supplied to customers outside the EU, the VAT treatment depends on the type of service and the place of supply rules. Many B2B services to non-EU customers are outside the scope of Danish VAT, meaning you do not charge Danish VAT but still record the revenue in your accounts. Some B2C services to non-EU customers may also be outside Danish VAT, while others can be taxable in Denmark. It is important to classify your services correctly and document where your customer is established.

Customs, import VAT and Incoterms

When you export goods, your customers may have to pay import duties and import VAT in their own country. The exact costs and procedures depend on the destination country and the customs classification of your goods. You should clearly state in your terms and conditions whether prices are “Delivered Duty Paid (DDP)” or whether the customer is responsible for customs and import VAT (for example “Delivered At Place (DAP)” or similar Incoterms).

If you import goods from outside the EU to Denmark before reselling them, you must normally pay Danish import VAT and any customs duties at the border. Import VAT can usually be deducted as input VAT in your Danish VAT return if the goods are used for your VAT-taxable business activities.

VAT registration thresholds and practical compliance

If your total annual turnover from taxable activities in Denmark and abroad exceeds DKK 50,000, you must register for Danish VAT. This threshold includes domestic sales and most cross-border supplies that are taxable in Denmark. Once registered, you must:

• Charge the correct VAT rate (Danish or foreign) depending on the rules for each transaction
• File VAT returns on time (usually quarterly or half-yearly for small businesses, monthly for higher turnover)
• Maintain detailed records of cross-border sales and purchases for at least the minimum statutory retention period

For OSS, you file a separate quarterly OSS return in addition to your regular Danish VAT return. OSS returns must be submitted and paid electronically in euros within the statutory deadline after the end of each quarter.

Invoicing, contracts and payment terms

Cross-border invoices must meet Danish invoicing requirements and, where relevant, the rules of the customer’s country. At a minimum, your invoice should include:

• Your business name, address and CVR number
• Customer’s name, address and VAT number for B2B sales
• Invoice date and unique invoice number
• Description of goods or services, quantity and delivery date
• Net amount, VAT rate and VAT amount, or a clear reference to reverse charge or export exemption

For international contracts, specify governing law (for example Danish law), jurisdiction, currency, payment terms, late payment interest and responsibility for customs and import VAT. Clear written terms reduce the risk of disputes and unpaid invoices when dealing with foreign customers.

Digital services and online platforms

If you sell digital products, software, online courses or subscriptions to customers in other countries, you must pay particular attention to the place of supply rules and the EUR 10,000 EU threshold. Many digital B2C services are taxed where the customer is located, which can quickly trigger OSS obligations if you sell across several EU countries.

If you sell via online platforms or marketplaces, check whether the platform is considered the deemed supplier for VAT purposes. In some cases, the platform is responsible for charging and remitting VAT, while you invoice the platform without VAT. The contractual setup and the platform’s VAT status determine your obligations.

Practical tips for Danish sole proprietors expanding abroad

Before you start selling to EU or non-EU customers, map out your expected customer base and turnover by country. This helps you decide whether you are likely to exceed the EU B2C threshold and whether OSS registration is relevant from the start. Implement invoicing and accounting software that supports multiple VAT rates and can distinguish between domestic, EU and non-EU transactions.

Keep all documentation related to transport, export, customer VAT numbers and place of supply. In case of a Danish VAT audit, well-organised records are essential to defend 0% VAT on exports and intra-EU supplies. When in doubt about complex cross-border scenarios, such as mixed supplies, chain transactions or services with multiple places of use, seek professional advice to ensure full compliance while optimising your tax position.

How to Change, Pause or Deregister Your Sole Proprietorship in Denmark

As your business evolves, you may want to change its details, temporarily pause activity or close your Danish sole proprietorship (enkeltmandsvirksomhed) altogether. Understanding the formal steps and the tax and bookkeeping consequences will help you avoid unexpected costs or problems with SKAT and Erhvervsstyrelsen.

Changing details of your sole proprietorship

Most changes to a sole proprietorship are made via Virk.dk using your MitID. Typical changes include your business address, industry code (branchekode/NACE), trade name, contact details and whether you are VAT registered.

In general, you must update your registration no later than 8 days after a relevant change. Key points:

• Address and contact details: Update your business address, email and phone on Virk.dk so SKAT and other authorities can reach you. This also affects where official letters are delivered.
• Industry code (branchekode): If the nature of your business changes (for example from IT consulting to construction), you should change your NACE code. This can affect your reporting obligations and eligibility for certain schemes.
• VAT status: If your annual turnover exceeds DKK 50,000 over a 12‑month period, you must register for VAT. If your turnover drops and you permanently stop VAT‑liable activities, you can deregister VAT while keeping the business active for non‑VAT activities.
• Trade name: You can change or add a business name (binavn) via Virk.dk. Make sure the name is not misleading and does not infringe existing registered names or trademarks.

Changes do not create a new legal entity. You remain personally liable for all obligations before and after the change.

Pausing your business activity

Danish law does not have a formal “suspension” status for a sole proprietorship in the same way as for companies, but in practice you can pause your business by:

• Stopping new business activity (no new sales, contracts or marketing)
• Deregistering VAT and payroll schemes if you no longer have taxable turnover or employees
• Keeping the CVR number active but dormant, or deregistering the business completely if you do not expect to trade again

If you pause without deregistering, you must still:

• Submit your annual personal tax return (årsopgørelse/udvidet selvangivelse) and report any remaining business income or losses
• Keep bookkeeping records for at least 5 years, even if there is no new activity
• File VAT returns for any period in which you were VAT registered, up to the effective deregistration date

Many sole proprietors choose to deregister VAT when pausing, while keeping the CVR number active in case they restart later. This reduces ongoing compliance but still allows you to resume more easily.

Deregistering your sole proprietorship (closing the business)

If you decide to stop trading permanently, you should formally deregister your sole proprietorship. This is done online via Virk.dk and is free of charge.

1. Stop business activity
   Complete any ongoing work, issue final invoices and collect outstanding payments. Clearly inform customers, suppliers and partners that you are closing the business.
2. Deregister VAT (moms)
   If you are VAT registered, you must deregister your VAT number via Virk.dk. You will be asked to provide the effective date of cessation. For the final VAT period you must:
   • Report all sales and purchases up to the closing date
   • Adjust for any private use of business assets if required
   • Pay any outstanding VAT to SKAT by the normal deadline for your reporting frequency (monthly, quarterly or half‑yearly)
3. Deregister as an employer (if applicable)
   If you have employees, you must:
   • Terminate employment contracts in line with Danish labour law and agreed notice periods
   • Pay final salary, holiday pay (feriepenge) and any outstanding benefits
   • File final A‑tax and AM‑bidrag reports via eIndkomst
   • Deregister as an employer on Virk.dk once all payroll obligations are settled
4. Settle business debts and obligations
   Pay outstanding supplier invoices, loans, leasing contracts and taxes. If the business cannot meet its obligations, you may need legal advice, as you are personally liable for debts in a sole proprietorship.
5. Deregister the business (CVR)
   On Virk.dk, choose to close your sole proprietorship (enkeltmandsvirksomhed). You will need to confirm:
   • The date you stopped business activity
   • That VAT and employer registrations have been handled
   • That you understand your continuing obligations for bookkeeping and tax
   After confirmation, your CVR number will be marked as ceased in the Central Business Register (CVR).
6. Handle final tax reporting
   In the income year you close the business, you must:
   • Prepare final accounts for the period from 1 January (or start date) to the closing date
   • Report your final business profit or loss on your personal tax return
   • Adjust for any business assets moved to private use (for example, a car or computer), which may trigger taxation of the market value
   If you have been using the business tax scheme (virksomhedsordningen) or capital return scheme (kapitalafkastordningen), you must close these correctly and may need professional advice to avoid unnecessary tax.

Bookkeeping and document retention after closure

Even after you deregister your sole proprietorship, you must keep your accounting records, invoices, bank statements and supporting documents for at least 5 years from the end of the financial year they relate to. SKAT can still carry out audits and request documentation for past years.

Make sure your digital records remain accessible (for example, export data from your accounting system and store it securely) and that you can link bank transactions to invoices and receipts if asked.

Restarting a business after closure

If you later decide to start trading again, you can register a new sole proprietorship via Virk.dk. In most cases you will receive a new CVR number. You will need to:

• Register for VAT again if you expect turnover above DKK 50,000 over 12 months
• Register as an employer if you plan to hire staff
• Set up new bookkeeping and bank arrangements

If you only paused activity without deregistering the CVR number, you can simply update your registrations (for example, re‑register for VAT) and resume operations.

When to seek professional help

Changes, pauses and deregistration can have significant tax and legal consequences, especially if you have employees, large assets, debt or are using special tax schemes. A Danish accountant or bookkeeper can help you:

• Choose the most efficient date for closing or pausing your business
• Handle final VAT, A‑tax and AM‑bidrag correctly
• Plan the transfer or sale of business assets to minimise tax
• Prepare final accounts and ensure compliance with all deadlines

Taking the time to close or pause your sole proprietorship properly reduces the risk of unexpected tax bills, fines or disputes with authorities and gives you a clean starting point for any future business activities.

Converting a Sole Proprietorship into an ApS (Private Limited Company)

Many Danish sole proprietors reach a point where operating as an enkeltmandsvirksomhed is no longer optimal. Converting into an ApS (private limited company) can reduce personal risk, make it easier to attract clients and investors, and provide more flexibility in tax planning. At the same time, it introduces stricter legal, accounting and reporting requirements. Understanding the legal and tax aspects of this conversion is essential before you change your business structure.

Why convert from a sole proprietorship to an ApS?

The main legal difference is liability. As a sole proprietor, you are personally liable for all business debts and obligations with your entire private wealth. In an ApS, liability is generally limited to the company’s capital, provided you have not given personal guarantees or acted negligently.

Other common reasons to convert include:

• Improved credibility with banks, suppliers and larger clients who often prefer dealing with limited companies
• Possibility to bring in co-owners and investors by issuing shares
• More flexible remuneration structure (salary plus dividends)
• Clearer separation between business and private finances
• Potential for more efficient long‑term tax planning when profits are retained in the company

Minimum capital and basic legal requirements for an ApS

To establish an ApS in Denmark, you must meet several statutory requirements:

• Minimum share capital: At least DKK 40,000 in share capital, which can be contributed in cash or as non‑cash assets (contribution in kind) that are valued and documented.
• Company form: The company must be registered as an ApS with the Danish Business Authority (Erhvervsstyrelsen) and receive its own CVR number.
• Articles of association: You must prepare articles of association and a foundation document that define, among other things, the company’s purpose, share capital, management structure and financial year.
• Management: At minimum, a board of directors or one or more executive directors (management can consist of a single director if desired).
• Registered office: A Danish business address for official correspondence and legal notifications.

Two main ways to convert: asset transfer vs. tax‑neutral restructuring

In practice, there are two typical approaches to moving from a sole proprietorship to an ApS:

1. Simple asset transfer: You close or scale down the sole proprietorship and transfer selected assets and activities to a newly formed ApS at market value.
2. Tax‑neutral business transfer (virksomhedsomdannelse): You transfer the entire business to an ApS under the Danish rules for tax‑neutral conversion, so that latent gains are not immediately taxed.

The tax‑neutral route is often attractive if your sole proprietorship owns assets with significant unrealised gains (for example goodwill, customer lists, equipment or property used in the business). However, it is subject to strict conditions and documentation requirements.

Key conditions for a tax‑neutral conversion

To use the Danish rules on tax‑neutral conversion of a sole proprietorship into an ApS, several core conditions typically need to be fulfilled:

• Transfer of the entire business: All assets and liabilities related to the business must be transferred to the ApS as a whole. You cannot pick and choose only profitable assets if you want tax neutrality.
• Valuation at tax values: Assets and liabilities are generally transferred at their existing tax values, not at market value, so that gains are not realised at the time of conversion.
• Share consideration: As the owner, you receive shares in the ApS as consideration for the transferred business. You normally cannot receive significant cash consideration if you want to maintain tax neutrality.
• Continuity: The ApS continues the same business activities, and tax positions such as depreciation bases and loss carry‑forwards are carried over to the company.
• Timely and correct registration: The conversion must be documented and registered correctly with the Danish Business Authority and the Danish Tax Agency (Skattestyrelsen), following the applicable deadlines and forms.

Because the detailed rules and documentation requirements are technical, most business owners use a certified accountant or tax adviser to structure and document a tax‑neutral conversion.

Using your sole proprietorship’s assets as ApS capital

If you do not wish to contribute DKK 40,000 in cash, you can often use your existing business assets as capital in the new ApS. This is done through a non‑cash contribution (apportindskud). Typical assets include equipment, inventory, receivables, intellectual property and sometimes business goodwill.

For non‑cash contributions, you must usually obtain a valuation and documentation that meet the requirements of the Danish Companies Act. In many cases, this involves an auditor’s statement confirming the value of the contributed assets and that they are suitable as share capital. The valuation must be realistic and justifiable, as it forms the basis for the company’s initial balance sheet and the protection of creditors.

Tax implications when you convert

From a tax perspective, the main change is that profits will in future be taxed at the corporate level instead of as personal business income. The Danish corporate income tax rate is 22%. As a sole proprietor, your business income is taxed as personal income, potentially at marginal rates significantly above 22% when including labour market contribution (AM‑bidrag) and top‑bracket tax.

Key tax points to consider include:

• Final year of the sole proprietorship: You must settle tax on the last income year of the sole proprietorship, including any balancing income from depreciable assets if they are sold or transferred at values above their tax base (unless you meet the conditions for tax‑neutral conversion).
• Corporate taxation going forward: The ApS pays 22% corporate tax on its taxable profits. If you take a salary from the ApS, this is taxed as personal income and subject to AM‑bidrag and personal tax rates.
• Dividends: Dividends distributed from the ApS to you as a shareholder are taxed as share income. Danish share income is taxed progressively, with a lower rate up to a certain annual threshold and a higher rate above that threshold. The exact thresholds and rates are adjusted periodically, so you should always check the current figures when planning distributions.
• Losses: Losses from the sole proprietorship cannot automatically be used by the ApS. Under certain conditions, they may still be used in your personal tax return, but not inside the company. This should be analysed before conversion.
• VAT and payroll taxes: VAT registration and any payroll‑related registrations (A‑tax, AM‑bidrag, ATP, holiday pay schemes) must be updated so that they are linked to the new CVR number of the ApS.

Practical steps in the conversion process

Although every case is different, a typical conversion from a Danish sole proprietorship to an ApS involves the following steps:

1. Clarify your goals (liability protection, tax planning, bringing in partners) and decide whether a simple asset transfer or a tax‑neutral conversion is more appropriate.
2. Prepare an opening balance sheet for the ApS, including a list of assets and liabilities to be transferred and their tax and accounting values.
3. Arrange financing of the minimum share capital of DKK 40,000, either in cash or via a documented non‑cash contribution of business assets.
4. Draft the foundation document and articles of association for the ApS, and decide on management structure, financial year and share classes (if any).
5. Register the ApS with the Danish Business Authority via Virk.dk, obtain the new CVR number and register for VAT, payroll taxes and other relevant schemes.
6. Transfer contracts, leases, supplier agreements, licences and insurance policies to the ApS where possible, and notify counterparties of the change of legal entity.
7. Update bank accounts so that the ApS has its own business account; avoid mixing private and company funds.
8. Adjust your invoicing, terms and conditions, website and marketing materials to show the new company name, CVR number and legal form (ApS).
9. Close or significantly reduce activity in the sole proprietorship and deregister it with the authorities once all obligations have been settled.

New accounting and reporting duties as an ApS

Once your business operates as an ApS, you are subject to the Danish Financial Statements Act and company law requirements. This includes:

• Preparation of annual financial statements in accordance with the applicable reporting class (most small ApS companies fall under class B)
• Filing of the annual report with the Danish Business Authority within the statutory deadline after the end of the financial year
• Maintaining proper bookkeeping and documentation that meets the stricter standards for companies
• In some cases, an audit or extended review, depending on the size of the company and whether shareholders opt out of audit when permitted by law

These obligations are more extensive than for a sole proprietorship, which is why many ApS owners choose to work closely with an accountant for ongoing bookkeeping, VAT returns, payroll and year‑end reporting.

When does conversion make sense?

Converting to an ApS is particularly relevant when your business has stable or growing profits, when you take on significant financial or contractual risk, or when you plan to hire employees or bring in partners. If your turnover is low or your activity is temporary, the additional costs and administrative burden of an ApS may outweigh the benefits.

Because the legal and tax consequences of a conversion can be long‑lasting, it is advisable to obtain tailored advice based on your actual income level, risk profile and growth plans before you decide to convert your Danish sole proprietorship into an ApS.

Common Legal Mistakes Made by New Sole Proprietors and How to Avoid Them

Many new sole proprietors in Denmark focus on getting clients and forget that even a small one-person business is tightly regulated. Below are some of the most common legal mistakes – and how to avoid them from day one.

1. Starting to Trade Before Proper Registration

A frequent mistake is issuing invoices or advertising services before the business is correctly registered with the Danish Business Authority (Erhvervsstyrelsen). Even a small freelance activity can be considered a business if it is carried out with a profit motive and a certain regularity.

If your annual turnover is expected to exceed DKK 50,000 within a 12‑month period, you must register for VAT (moms). Many new sole proprietors underestimate their turnover and delay VAT registration, which can lead to retroactive VAT claims, interest and possible fines.

To avoid problems, register your sole proprietorship (enkeltmandsvirksomhed) and, if relevant, VAT as soon as you have a realistic plan and signed agreements that indicate you will reach the threshold.

2. Mixing Personal and Business Finances

Because a sole proprietorship is not a separate legal entity, many owners use their private bank account for business income and expenses. This makes it difficult to document transactions and increases the risk of tax corrections during a SKAT audit.

Even though you are not legally required to open a dedicated business account, it is strongly recommended to separate finances. Use one account for business income, expenses, VAT and tax instalments, and keep private spending elsewhere. This makes bookkeeping, cash‑flow management and documentation far easier and reduces the risk of errors in your tax return.

3. Ignoring VAT Rules and Deadlines

New sole proprietors often misinterpret which sales are subject to VAT, when VAT becomes due and how often they must report it. Common errors include:

• Charging VAT on VAT‑exempt services (for example certain health services, financial services or teaching activities that meet specific criteria)
• Failing to charge VAT on standard consulting, design, IT or trade services that are fully VAT‑liable
• Not adjusting VAT treatment for cross‑border B2B and B2C sales within and outside the EU
• Missing VAT reporting deadlines and payment dates

In Denmark, most small businesses report VAT either quarterly or half‑yearly, depending on their turnover and SKAT’s allocation. Late filing or late payment can trigger surcharges and interest. Always check your assigned VAT period in TastSelv Erhverv and set up reminders well before the deadline.

4. Poor or Incomplete Bookkeeping

Many new sole proprietors underestimate the legal requirements for bookkeeping. Danish law requires that you keep accurate, chronological records of all income and expenses and store documentation (invoices, receipts, bank statements, contracts) for at least five years.

Typical mistakes include:

• Not issuing proper invoices with required information (name, address, CVR number if registered, invoice number, date, description of goods/services, price, VAT amount and rate)
• Not reconciling bank accounts with bookkeeping records
• Throwing away small receipts or failing to record cash payments
• Using spreadsheets without clear structure or backup

To avoid problems, implement a simple accounting system from the beginning. This can be cloud‑based accounting software or cooperation with a professional bookkeeper or accountant who knows Danish rules.

5. Misunderstanding Personal Tax and AM-bidrag

As a sole proprietor, business profit is taxed as your personal income. Many new owners confuse corporate tax rules with personal tax and do not set aside enough money for tax and the mandatory labour market contribution (AM‑bidrag).

Key points include:

• AM‑bidrag is 8% of your earned income before income tax
• Personal income tax is progressive, with municipal tax, health contributions and state tax bands that increase with income
• There is a separate top tax (topskat) on income above a certain annual threshold
• You can use the business tax schemes (virksomhedsordningen or kapitalafkastordningen) if you meet the conditions and want more flexible tax planning

A common mistake is not updating your preliminary income assessment (forskudsopgørelse) in TastSelv when your business income changes. This can lead to large residual tax (restskat) plus interest. Update your expected profit during the year and transfer tax and AM‑bidrag to a separate account so the funds are available when SKAT settles your final tax.

6. Using CPR Instead of CVR in the Wrong Contexts

Some sole proprietors use their CPR number on invoices, websites and contracts even after obtaining a CVR number. This raises privacy concerns and can conflict with data protection best practice.

Once your business is registered and you receive a CVR number, use it as your public business identifier on invoices, your website, marketing materials and contracts. Limit the use of your CPR number to communication with authorities, banks and where specifically required by law.

7. Non‑Compliant Contracts and Terms with Customers

Many new businesses rely on informal email agreements or generic templates found online that do not reflect Danish law. This can create disputes about delivery, payment, delays, defects and liability.

Typical issues include:

• No clear written agreement on scope of work, deadlines and price
• No specified payment terms, late payment interest or reminder fees
• Unclear or unenforceable limitation of liability clauses
• Not distinguishing between B2B and consumer (B2C) rules, especially regarding cancellation rights and complaint periods

To avoid conflicts, prepare simple, clear terms and conditions that comply with Danish contract and consumer law. Ensure that clients accept them in writing before you start work. For consumer sales, respect mandatory rules on right of withdrawal, information duties and complaint handling.

8. Overlooking Employee and Freelancer Rules

Some sole proprietors hire help and treat workers as “freelancers” without checking whether they are legally employees. If SKAT or other authorities reclassify a freelancer as an employee, you may become liable for unpaid holiday pay, social contributions, ATP, withholding tax (A‑skat) and AM‑bidrag.

Warning signs of an employment relationship include fixed working hours, integration into your organisation, use of your tools and systems, and lack of financial risk for the worker. Before engaging people, clarify whether they are truly independent businesses with their own CVR number and multiple clients.

If you hire employees, you must register as an employer, withhold A‑tax and AM‑bidrag, pay ATP and comply with rules on employment contracts, working time, holiday pay and, where applicable, collective agreements.

9. Ignoring GDPR and Data Protection Duties

Even a one‑person business must comply with the EU General Data Protection Regulation (GDPR) and Danish data protection rules when processing personal data. Common mistakes include:

• Collecting more personal data than necessary from clients
• Not having a privacy policy on the website
• Using insecure email or cloud services without data processing agreements
• Keeping personal data longer than needed without a clear retention policy

Map what personal data you collect, why you collect it and how long you keep it. Inform clients transparently, secure the data with appropriate technical and organisational measures and sign data processing agreements with IT and cloud providers that handle personal data on your behalf.

10. Forgetting Mandatory Insurance and Risk Management

While not all insurances are legally mandatory, many are effectively required in practice. New sole proprietors often skip insurance to save money, which can be very costly after a claim.

Depending on your activity, you may need professional liability insurance, product liability insurance or business contents insurance. If you have employees, workers’ compensation insurance (arbejdsskadeforsikring) is mandatory. Some industries also require specific licences or insurances to operate legally.

Assess your risks with an insurance adviser and ensure that your coverage matches your actual activities and contract obligations.

11. Not Updating the Business When Circumstances Change

Many owners forget to update their registration when they change address, business activity, VAT status or when they decide to pause or close the business. This can lead to incorrect tax assessments and ongoing reporting duties even if you are no longer trading.

Always update your details in the Danish Business Register (CVR) and in TastSelv Erhverv when you:

• Change business address or contact details
• Add or change business activities
• Register or deregister for VAT
• Start or stop employing staff
• Decide to temporarily suspend or permanently close the business

12. Trying to Handle Everything Without Professional Help

A final common mistake is waiting too long to ask for professional advice. Danish tax, VAT, labour and data protection rules are complex, and errors can be expensive to correct later.

Working with a Danish accountant or bookkeeping firm from the beginning helps you:

• Choose the right tax scheme for your situation
• Set up compliant bookkeeping and invoicing routines
• Meet all VAT, tax and reporting deadlines
• Structure contracts, employment relationships and GDPR documentation correctly

With the right guidance, you can focus on growing your business while staying compliant with Danish law and avoiding the most common legal pitfalls for new sole proprietors.

Final Reflections

Initiating a sole proprietorship in Denmark is an exciting venture that provides opportunities for self-employment and business growth. However, it requires careful planning and adherence to legal and regulatory requirements. Understanding these facets ensures you can navigate your entrepreneurial journey successfully. With the right preparation, resources, and commitment, a Danish sole proprietorship can prove to be a fulfilling endeavor, paving the way for personal and professional growth.
