Registration in Denmark

Denmark is one of the more attractive destinations for foreigners who decide to work and live abroad permanently. Upon arrival in this country, it is necessary to register your place of residence at the local municipality office, or Kommune. You will need to present the appropriate document, such as an identity card or passport, to confirm your identity and current address.

The most important information about registering in Denmark

Staying and working in Denmark for more than three months involves registering your address with Folkeregister. Immediately after arriving in Denmark, go to your local municipality to register your new address. You will need an identity document, such as an ID card or passport, to register. In the process, you will receive a CPR number, which is key to using most available public services, including Danish health care.

In Denmark, registering your registration requires that you actually reside on Danish territory, which completely rules out the possibility of having two residences at the same time. It is necessary that you have a premises where registration can be carried out. You should always be registered at the address where you actually currently live.

After receiving the certificate, further registration with the Central Register of Persons (CPR) is necessary. Within five days of receiving the certificate, you must go to the nearest Population Registration Office. During this visit you will receive:
- A Yellow Card, which is a health insurance card containing, among other things, contact information for the doctor of your choice.
- Health insurance, which you will obtain through an EU Resident Certificate.
- The right to receive Danish medical services on an equal basis as Danish citizens.

Being registered in Denmark comes with many benefits, including the ability to apply for Danish unemployment benefits (A-kasse), which requires a Danish address.

Those staying in Denmark for less than three months are not required to register. On the other hand, those who are looking for work can stay in the country for up to six months without registering. However, if one plans a longer stay, a visit to the State Administration Office is necessary to register in the system and obtain the appropriate certificate. If you are keen on staying legally in Denmark, it is necessary to start this process within three months of arrival.

To work legally in Denmark, you need more than just a residence permit and a CPR number. A key document is a tax card (the so-called TAX card), which is needed for payment of wages by the employer. An electronic version of this card is issued by the SKAT tax office. If you want it to be issued, the first step is to contact the SKAT tax office. You can fill out an application online or submit it in person at the office, in physical form. The tax card will then be issued electronically.

If you plan to change your address after receiving your CPR number and registering at your current address, you can update your information yourself online. To do this, we use NemID and visit www.borger.dk. It is important to inform the local authorities of the new address within five days of the change.

Using the services of a professional accounting firm can greatly facilitate the completion of any required forms. This type of support not only saves you time and stress, but also provides you with access to additional information on the necessary paperwork for short and long-term residence in Denmark.

Types of registration in Denmark: CPR, tax, social security and business registration

Before you start working, living or running a business in Denmark, you usually need several different registrations. The most important are the civil registration number (CPR), tax registration, social security registration and, for entrepreneurs, business registration with the Danish Business Authority. Understanding how these registrations are connected will help you avoid delays, penalties and problems with Danish authorities.

CPR – Danish civil registration number

The CPR number is the cornerstone of almost all formalities in Denmark. It is a 10-digit personal identification number used by tax authorities, banks, healthcare, municipalities and most public and private institutions.

You normally need a CPR number if you:

Registration for a CPR number is done at the local Citizen Service (Borgerservice) or International Citizen Service, usually after you obtain an EU registration certificate or residence permit, and a rental contract or other proof of address. Once you receive your CPR number, you can register with a general practitioner (GP), open a Danish bank account and access most digital self‑service solutions.

Tax registration – Danish tax number, preliminary income assessment and tax card

Tax registration in Denmark is handled by the Danish Tax Agency (Skattestyrelsen). Depending on your situation, you may need:

When you start working, your employer must have access to your tax card in the online system. The tax card is based on your preliminary income assessment, which includes your expected annual income, deductions and personal allowance.

Key elements of Danish income tax include:

All these taxes are coordinated automatically through your tax card, but only if your registration is correct and up to date. Incorrect or missing tax registration can lead to emergency taxation at a very high rate and later corrections. Professional accounting support is often useful when you have multiple income sources, foreign income or complex deductions.

Social security registration – health insurance and social benefits

In Denmark, social security is closely linked to your residence and work status. Once you are registered with a CPR number and considered resident under Danish rules, you are normally covered by the Danish public health insurance and other social security schemes.

Key aspects of social security registration include:

For cross‑border workers and employees posted to or from Denmark, EU coordination rules and international social security agreements determine in which country you are insured. In such cases, A1 certificates and other documentation may be required. Correct classification is essential to avoid double contributions or loss of coverage.

Business registration – CVR number and VAT (Moms)

If you run a business in Denmark, you must register it with the Danish Business Authority (Erhvervsstyrelsen). After registration, your company receives a CVR number, which is the business identification number used for invoices, contracts, tax and VAT reporting.

You must register a business if you:

Typical forms of business in Denmark include:

VAT (moms) registration is mandatory when your VAT‑liable turnover exceeds DKK 50,000 in any 12‑month period. The standard VAT rate is 25% and applies to most goods and services. Some sectors are exempt from VAT, such as most financial services, insurance and certain healthcare and educational services. VAT‑registered businesses must submit VAT returns and pay VAT either monthly, quarterly or half‑yearly, depending on turnover.

How the different registrations interact

In practice, CPR, tax, social security and business registrations are interconnected:

Because of this close interaction, errors in one registration often create problems in others. For example, an incorrect address in the CPR register can lead to wrong municipal tax rates, and missing VAT registration can result in fines and back payments. A professional accounting partner can coordinate all registrations, monitor deadlines and ensure that your Danish obligations are handled correctly from the start.

Required documents and eligibility criteria for registration in Denmark

To register correctly in Denmark, you must meet specific eligibility criteria and prepare a defined set of documents. The exact requirements depend on your nationality, length and purpose of stay, and whether you register as a private individual, employee, student, self-employed person or business owner.

1. CPR registration (civil registration number)

The Danish CPR number is the key to almost all public and many private services. You normally need a CPR if you stay in Denmark for more than 3 months (or more than 6 months as a posted worker).

Eligibility – EU/EEA and Swiss citizens

You can obtain a CPR number if you have a legal basis for residence in Denmark, for example:

In practice, you will first need an EU residence document (EU registration certificate) issued by SIRI before you can register for CPR at the local Citizen Service (Borgerservice).

Eligibility – non-EU/EEA citizens

Non-EU/EEA citizens generally need:

The permit is usually issued by SIRI or the Danish Immigration Service and must be valid at the time of CPR registration.

Key documents for CPR registration

All foreign documents may need to be translated into English or Danish and, in some cases, legalised or apostilled, depending on the country of origin.

2. Tax registration (Skattekort and tax number)

Anyone who earns taxable income in Denmark must be registered with the Danish Tax Agency (Skattestyrelsen). This applies to employees, self-employed persons and many cross-border commuters.

Eligibility for tax registration

Key documents for tax registration

Based on this information, Skattestyrelsen issues your electronic tax card (skattekort), which your employer uses to withhold A-tax and labour market contributions (AM-bidrag).

3. Social security registration

In Denmark, social security is closely linked to your residence and employment status. Most employees and self-employed persons working in Denmark are covered by the Danish social security system and pay the 8% labour market contribution (AM-bidrag) on their income.

Eligibility for Danish social security coverage

Key documents for social security purposes

Once registered with CPR and a Danish address, you are normally entitled to a Danish health card (yellow card) and access to the public healthcare system.

4. Business registration (CVR number)

If you run a business in Denmark, you usually need to register it with the Danish Business Authority (Erhvervsstyrelsen) and obtain a CVR number. This applies to both Danish residents and foreign entrepreneurs operating in Denmark.

Eligibility for business registration

Key documents for business registration

Depending on expected turnover, you may also need to register for VAT (moms) if your taxable turnover in Denmark exceeds DKK 50,000 over a 12‑month period.

5. Additional requirements for specific groups

Employees

Students

Family members

6. Practical tips for documents and compliance

To avoid delays in Danish registration processes, ensure that:

Professional accounting and tax support can help verify that your documentation and eligibility meet current Danish legal requirements, especially in more complex situations such as cross‑border work, combined employment and self-employment, or company establishment.

Deadlines and typical timelines for obtaining Danish registration numbers

Understanding the deadlines and typical processing times for Danish registration numbers is crucial if you want to start work, receive salary, open a bank account or access public services without delays. In Denmark, the most important numbers are the CPR number (civil registration), the tax number / tax card and, for businesses, the CVR number. Each of them has its own timeline and practical consequences if you apply too late.

CPR number – when you must register and how long it takes

If you move to Denmark to live and work, you generally need to register your address and apply for a CPR number within 5 days of obtaining a place of residence. In practice, you should book an appointment with the local Citizen Service (Borgerservice) as soon as you have a signed rental contract or other valid proof of address.

Typical processing times for a CPR number are:

Without a CPR number you cannot get a Danish MitID, register with a GP, receive most social benefits or access many online self‑service solutions. For employees, a delayed CPR often means delays in setting up a bank account and receiving salary, so it is important to plan the registration as early as possible.

Tax number and tax card – deadlines for employees and self‑employed

To have the correct tax withheld from your salary, you must have a Danish tax number and a tax card issued by the Danish Tax Agency (Skattestyrelsen). If you already have a CPR number, your tax number is linked to it. If you work in Denmark without a CPR, you can obtain a temporary tax number.

Key deadlines and timelines:

If you are self‑employed, you must register your expected income and pay B‑skat (on‑account tax) and AM‑bidrag (labour market contribution of 8%) during the year. You should register your business and expected profit with the Tax Agency no later than when you start your activity, so that advance tax instalments can be calculated and set up in time.

CVR number – business registration deadlines and processing

Any business that carries out commercial activity in Denmark must be registered with the Danish Business Authority (Erhvervsstyrelsen) and obtain a CVR number. This applies to sole proprietors, partnerships and companies, including many foreign companies with a permanent establishment in Denmark.

Typical rules and timelines:

Typical timelines for other key registrations

In addition to CPR, tax and CVR numbers, there are several related registrations with their own timelines:

What happens if you miss a deadline?

Missing registration deadlines in Denmark does not usually result in criminal penalties for ordinary delays, but it can have significant financial and practical consequences:

To avoid these issues, it is best to prepare all documentation in advance and start each registration process as soon as you know your move or business start date. A professional accounting partner in Denmark can coordinate CPR, tax and CVR registration for you, monitor deadlines and communicate with the authorities to minimise delays and unexpected costs.

Registration of foreign workers and cross-border commuters in Denmark

Foreign employees and cross-border commuters working in Denmark are subject to specific registration rules that determine access to the Danish labour market, social security and the correct taxation of income. Proper registration is essential to obtain a CPR number, tax card, social security coverage and to avoid double taxation.

Who is considered a foreign worker or cross-border commuter?

A foreign worker is any person who does not have Danish citizenship and comes to Denmark to work as an employee or self-employed. A cross-border commuter is typically someone who lives in another country (for example Germany, Sweden or Poland) and regularly travels to Denmark to work, without moving their residence to Denmark.

The key distinction is whether you become tax resident in Denmark or remain tax resident in another country and are taxed in Denmark only on Danish-source income. This depends mainly on the length of stay, family situation and the nature of your work.

Basic registration steps for foreign employees

Most foreign employees must complete the following steps before or shortly after starting work in Denmark:

  1. Obtain an employment contract or written job offer from a Danish employer.
  2. Apply for a work and residence permit if you are not an EU/EEA or Swiss citizen.
  3. Register with the Danish Tax Agency (Skattestyrelsen) to obtain a Danish tax number and tax card.
  4. Apply for a CPR number (civil registration number) if you meet the conditions for registration in the Danish National Register.
  5. Register for social security and health coverage, usually through CPR registration.

In many cases, the employer or a payroll provider will assist with the initial tax and social security registration, but the employee remains responsible for ensuring that the information is correct and complete.

Registration for EU/EEA and Swiss citizens

EU/EEA and Swiss citizens have the right to work in Denmark without a work permit, but must still register if they stay and work in Denmark for more than a short period. In practice:

EU/EEA workers are usually covered by the social security system of the country where they physically work, unless specific rules for posted workers or multi-state workers apply.

Registration for non-EU citizens

Non-EU citizens generally need a valid work and residence permit before starting work in Denmark. The type of permit depends on your qualifications and job offer, for example:

Only after receiving the residence and work permit can you register with the Danish authorities for tax and CPR purposes. Working without the correct permit can lead to fines, deportation and a ban on re-entry.

Tax number, tax card and CPR for foreign workers

All foreign workers who earn income in Denmark must be registered with the Danish Tax Agency. Depending on the length and nature of your stay, you will receive:

The tax card determines how much tax your employer withholds from your salary. Without a valid tax card, the employer is required to withhold tax at a high default rate, which can significantly reduce your net pay until the situation is corrected.

Special rules for cross-border commuters

Cross-border commuters who live in another country and work in Denmark are generally taxed in Denmark on income from Danish employment. Whether they become fully tax resident in Denmark depends on the number of days spent in Denmark, the location of their home and family, and any applicable double tax treaty.

Typical situations include:

For cross-border commuters, correct allocation of income and expenses between Denmark and the country of residence is crucial to avoid double taxation and to benefit from any cross-border tax reliefs that may apply under Danish law and relevant tax treaties.

Social security and health insurance for foreign workers

As a rule, you are covered by the social security system of the country where you physically work. For most foreign employees working in Denmark, this means Danish social security contributions and access to the Danish public healthcare system after CPR registration.

Exceptions apply to posted workers and people working in more than one EU/EEA country, who may remain covered by the social security system of their home country if they hold a valid portable document (such as an A1 certificate). In such cases, it is essential to coordinate documentation between the employer, the Danish authorities and the home-country institution.

Employer obligations when hiring foreign workers

Danish employers hiring foreign workers must:

Failure to comply with these obligations can lead to significant penalties, back taxes and reputational risk for the company.

How professional support can help foreign workers and commuters

The rules for registration, tax and social security for foreign workers and cross-border commuters in Denmark are complex and depend on individual circumstances, including family situation, residence, length of stay, salary level and type of work. Professional accounting and tax support helps to:

Proper registration from the start reduces the risk of unexpected tax bills, double taxation and problems with social security or residence status in Denmark.

Tax implications of registration in Denmark for employees and self-employed

Registering in Denmark has direct consequences for how and where you pay tax. Once you obtain a CPR number and register with the Danish Tax Agency (Skattestyrelsen), you are usually considered tax liable to Denmark on your Danish income. Depending on your situation, you may become either fully tax liable (taxed on worldwide income) or limited tax liable (taxed only on certain Danish-source income).

Tax liability after registration

If you move to Denmark to live and work here, you will in most cases become fully tax liable from the date of arrival. This means that Denmark can tax your worldwide income, although double tax treaties may limit Danish taxation on some foreign income. If you only work in Denmark for a short period, live abroad and do not move your centre of life to Denmark, you are usually treated as limited tax liable and taxed only on Danish salary and certain other Danish-source income.

Registration with the Civil Registration System (CPR) and obtaining a tax card are key steps. Without a tax card, your employer must withhold 55% A-tax (income tax) from your salary. Once your tax card is issued, withholding is adjusted to the correct rates based on your expected annual income and deductions.

Tax implications for employees

Employees in Denmark pay A-tax, which is withheld directly from salary by the employer. The total tax burden consists of several components:

After the 8% labour market contribution is deducted, the remaining income is subject to municipal, church and state tax. Denmark applies a progressive system. In addition, there is a cap on the total marginal tax rate on personal income (excluding AM-bidrag) of approximately 52%. Including the 8% labour market contribution, the maximum marginal tax rate on salary is just under 60%.

All employees are entitled to a personal allowance that is tax free. The allowance reduces the tax you pay on your income. If you are married and your spouse does not use their full allowance, part of it can be transferred to you.

When you register as an employee, you must inform Skattestyrelsen of your expected annual income and deductions. This is done in your preliminary income assessment (forskudsopgørelse). Based on this, your tax card is created and your employer withholds tax accordingly. If your income or deductions change during the year, you should update your preliminary assessment to avoid underpayment or overpayment of tax.

Special expat tax scheme

Certain highly paid employees and researchers recruited from abroad can apply for the Danish expat tax scheme. Under this scheme, salary and certain benefits can be taxed at a flat rate of 27% plus 8% labour market contribution, resulting in an effective rate of approximately 32%. The scheme can be used for up to 7 years if specific salary thresholds and other conditions are met. Registration in Denmark and correct classification of your employment are crucial to determine whether you qualify and to apply within the required time limits.

Tax implications for self-employed

If you register as self-employed in Denmark, for example by obtaining a CVR number and registering for VAT where required, you are taxed under the rules for business income. Your profit is calculated as business income minus deductible business expenses. This profit is then taxed as personal income, combined with other income you may have.

Self-employed individuals can choose between different tax methods, such as the business tax scheme (virksomhedsordningen) or the capital return scheme (kapitalafkastordningen), if they meet the conditions. These schemes can affect how interest, capital and business profits are taxed and may provide opportunities for tax optimisation, for example by allowing you to retain profits in the business at a lower tax rate and defer personal taxation.

As a self-employed person, you are responsible for:

Self-employed individuals also pay the 8% labour market contribution on business profits. The same personal allowance and progressive tax rates apply as for employees, but the calculation of taxable income and the timing of tax payments differ.

Social security and ATP contributions

Registration in Denmark often brings you under the Danish social security system, unless an EU regulation or a social security agreement with another country states otherwise. Employees and employers pay contributions to various schemes, including the statutory labour market supplementary pension (ATP). For employees, ATP contributions are shared between employer and employee and are typically a fixed amount per hour or month, depending on working hours.

For self-employed persons, ATP contributions are usually voluntary, but participation can affect future pension rights. In addition to ATP, there may be other labour market schemes agreed in collective agreements, such as occupational pension contributions, which have tax implications and are often tax deductible within certain limits.

Double taxation and international aspects

If you have income from more than one country, registration in Denmark can trigger questions about double taxation. Denmark has double tax treaties with many countries that determine which country has the primary right to tax specific types of income and how double taxation is avoided, typically through exemption or credit methods.

Employees who commute across borders or work partly in Denmark and partly abroad must pay particular attention to where they are tax resident, where the work is physically performed and how salary is allocated between countries. Self-employed individuals with foreign clients or permanent establishments abroad face similar issues. Correct registration and documentation are essential to apply the treaty rules and avoid paying tax twice on the same income.

Reporting obligations and deadlines

After registration, both employees and self-employed persons must comply with Danish reporting obligations. Employees normally receive a pre-completed annual tax assessment (årsopgørelse) based on information from employers, banks and other institutions. You must check this assessment and correct it if necessary within the deadline to ensure that deductions and income are correctly reported.

Self-employed persons must submit more detailed information on business income and expenses, usually through the extended tax return. Deadlines differ for individuals who file electronically and for those who use authorised advisers, but in all cases late filing can lead to penalties and estimated assessments.

Correct and timely registration at the start of your stay or business activity in Denmark is therefore crucial. It determines your tax status, the rates applied to your income and your access to deductions and special schemes, and it helps you avoid unexpected tax bills and interest charges later.

Digital tools used in the registration process: MitID, e-Boks and online self-service

Most registrations in Denmark are handled digitally. To obtain a CPR number, tax number, social security coverage or to register a business, you will almost always need three key tools: MitID, e-Boks and the public online self-service portals (such as borger.dk and virk.dk). Understanding how they work will make the entire registration process faster and more predictable.

MitID – your digital ID in Denmark

MitID is the national digital identification system used to log in to public authorities, banks and many private companies. You need MitID to:

To obtain MitID, you normally need a CPR number and valid ID (passport or national ID card). In many cases, foreign employees receive MitID after registering at the International Citizen Service or the local municipality when they obtain their CPR number. Some banks can also help you create MitID when you open a Danish bank account, but they will still require proof of identity and Danish registration.

MitID is usually used through a mobile app, but there are also alternative solutions for users without smartphones. During registration you set up a user ID and authentication method. Keep in mind that MitID is personal and must never be shared with your employer, accountant or family members. If you suspect misuse, it is important to block MitID immediately and contact support.

e-Boks – your secure digital mailbox

e-Boks is a secure digital mailbox where you receive official letters from Danish authorities, banks and many companies. Once you are registered in Denmark and have MitID, you are generally required to receive post from public authorities digitally through e-Boks or the Digital Post system.

Typical documents you receive in e-Boks include:

You access e-Boks by logging in with MitID. It is important to check your e-Boks regularly, because deadlines for appeals, documentation requests or corrections often run from the date a letter is delivered digitally, not from the day you read it. Missing a deadline because you did not open e-Boks does not normally stop the decision from taking effect.

For companies, e-Boks (or Digital Post for businesses) is equally important. Once a business is registered with a CVR number, it must be able to receive digital post from authorities. This is crucial for VAT notifications, tax control letters, reminders about reporting deadlines and correspondence with the Danish Business Authority.

Online self-service portals: borger.dk, skat.dk and virk.dk

Most registrations and updates in Denmark are done through official self-service portals. The most important ones are:

On borger.dk you can, among other things, register your address, choose a doctor, apply for certain benefits and access links to CPR and social security related services. For many foreign workers, borger.dk is the starting point for information about moving to Denmark, registering family members and understanding rights in the Danish welfare system.

On skat.dk you can:

On virk.dk you handle most business registrations and changes, such as:

All these portals require MitID for secure login. Information and forms are available in Danish, and many key areas are also available in English, but some detailed guidance and letters may only be in Danish. For this reason, many foreign individuals and businesses choose to work with an accountant or adviser who can handle digital communication and filings on their behalf.

How an accountant can help you navigate digital tools

Although MitID, e-Boks and online self-service portals are designed to be user-friendly, the combination of language barriers, strict deadlines and complex tax rules can be challenging. An accountant familiar with Danish digital systems can:

Using these digital tools correctly from the start reduces the risk of penalties, interest and unnecessary correspondence with authorities. It also ensures that your Danish registration – whether as an employee, self-employed person or company – is complete and up to date.

Common mistakes during registration in Denmark and how to avoid them

Many delays and tax problems in Denmark come from simple mistakes made at the registration stage. Below we describe the most common issues we see in practice and how to avoid them, both for employees and the self-employed.

1. Incorrect or incomplete personal data

One of the most frequent errors is providing data that does not exactly match your passport or national ID. Even a small difference in spelling, middle name or date of birth can cause problems with CPR, tax registration and access to public services.

Always check that:

Before submitting any form to the Danish authorities, compare all data with your passport and residence documents. Inconsistencies can delay CPR, tax card and access to NemKonto.

2. Wrong address or lack of proof of residence

For most registrations you must have a valid address in Denmark and be able to document it. A common mistake is using a temporary or informal address that cannot be confirmed by the municipality.

Typical problems include:

Make sure you have a valid rental contract or other written documentation of your housing situation. If you move, report your new address to the municipality within the deadline specified in your registration letter, usually within a few days of moving.

3. Confusing CPR registration with tax registration

Many newcomers assume that once they have a CPR number, their tax matters are automatically in order. In reality, CPR and tax registration are two separate processes.

Typical mistakes:

If you start work without a tax card, your employer may be forced to withhold tax at a very high rate. Always register with the tax authorities as soon as you know your employment details and expected income, and update your preliminary income assessment when your situation changes.

4. Incorrect assessment of tax residence and cross-border status

Foreign workers and cross-border commuters often misjudge whether they are tax residents in Denmark. This can lead to double taxation or underpayment of tax.

Common errors include:

If you live in one country and work in Denmark, or if you have income from several countries, it is important to clarify your tax residence status and cross-border rules at the registration stage. Keep detailed records of days spent in Denmark, employment contracts and foreign tax documents.

5. Missing or incorrect documentation

Incomplete documentation is one of the main reasons for delays in CPR, tax and social security registration.

Typical missing documents are:

Before booking an appointment or submitting an online application, check the official list of required documents and prepare clear, readable copies. If your documents are not in English, Danish, Norwegian or Swedish, you may need an authorised translation.

6. Wrong classification as employee or self-employed

Some people register incorrectly as self-employed when, in practice, they work like employees, or the other way around. This has consequences for tax, social security and VAT.

Typical mistakes:

Before choosing your registration form, analyse how you actually work: who controls your working time, who bears the economic risk, and how many clients you have. Correct classification at the start helps avoid later re-assessments and additional tax.

7. Ignoring deadlines and typical processing times

Another common mistake is starting the registration process too late. This can lead to delayed salaries, blocked benefits and incorrect tax withholding.

Problems often arise when:

Plan your arrival and registration so that you have time to obtain a CPR number, tax card and access to digital tools before or shortly after your first working day. Always read letters from the authorities carefully and respond within the indicated deadlines.

8. Not setting up or using digital tools correctly

In Denmark, most communication with public authorities is digital. Problems with MitID, e-Boks and NemKonto can block your access to important information and payments.

Frequent mistakes include:

As soon as you receive your CPR number, set up MitID, activate your e-Boks and choose a NemKonto. Check your digital mailbox regularly, as most decisions and requests from authorities are sent there only.

9. Underestimating the importance of updating data

Registration in Denmark is not a one-time action. Many people forget to update their data when their situation changes, which leads to incorrect tax, loss of benefits or problems with the municipality.

Typical omissions:

Whenever your living, work or family situation changes, check whether you need to update your information with the municipality, the tax authorities or other institutions. Timely updates help avoid corrections and back payments later.

10. Lack of professional support in complex cases

Many people try to handle complex cross-border or business situations alone, relying only on general information. This often leads to incomplete or incorrect registration.

If you:

it is worth consulting a professional advisor familiar with Danish rules. Properly planned and correctly executed registration at the beginning usually costs less than correcting mistakes after a tax audit or re-assessment.

By avoiding these common mistakes and preparing your documentation and digital access in advance, you can make the Danish registration process smoother, reduce the risk of tax problems and focus on your work or business instead of formalities.

Updating your registration data in Denmark when your situation changes

When your personal or business situation changes in Denmark, you are legally required to update your registration data. This applies both to private individuals (CPR and tax registration) and to companies (CVR and tax/VAT registration). Keeping your data up to date ensures correct taxation, access to public services and avoidance of penalties.

Which changes must be reported and where

Most changes are reported digitally using MitID via the self-service solutions of the Danish authorities. In general:

Updating your CPR data and address

If you move within Denmark, you must report your new address to the Folkeregister no later than 5 days after moving. You do this online via borger.dk using MitID. When your move is registered:

If you move to Denmark from abroad and meet the conditions for registration (e.g. EU/EEA residence rights or valid Danish residence permit), you must appear in person at the local International Citizen Service or Borgerservice to obtain a CPR number, health card and registration of your address. After registration, later address changes are handled online.

Changes in family and personal status

Certain life events must also be registered or updated:

These changes can influence your tax situation, for example eligibility for certain deductions, child benefits or the way your tax card is calculated.

Updating tax information as an employee

Your Danish tax is based on your preliminary income assessment (forskudsopgørelse). You must update it in TastSelv on skat.dk when your situation changes, for example:

In TastSelv you can adjust:

If you do not update your data, you risk paying too little tax during the year and facing an additional payment (restskat) with interest and possible surcharge, or paying too much and waiting for a refund.

Updating data as self-employed or freelancer

If you are self-employed or have B-income, you must ensure that your tax and business registrations reflect your actual activity and income. You should update your information when:

As a self-employed person you usually pay tax via B-tax (B-skat) and on-account payments. You can adjust the size and frequency of these payments in TastSelv if your expected income changes. This helps avoid large additional tax bills after the income year.

Updating business registration (CVR) data

Companies and sole proprietorships registered under a CVR number must keep their information up to date in the Central Business Register. Via virk.dk you must update, among other things:

If your turnover falls below the VAT registration threshold or you stop your activity, you must deregister VAT and possibly close the company. Failure to update may lead to estimated VAT/tax assessments and penalties.

Changes affecting social security and benefits

Danish social security and many benefits are linked to your CPR, address and income. You must report changes to Udbetaling Danmark or your municipality if they may affect:

Typical changes include moving in or out with a partner, changes in income, starting or stopping work, or moving abroad. If you do not report changes, you may have to repay benefits with interest and risk sanctions.

Moving abroad or becoming a cross-border commuter

If you leave Denmark or become a cross-border commuter, you must update both your CPR and tax status:

In many cases you will need to submit additional documentation to SKAT to determine your tax residency and avoid double taxation. This is especially important if you keep property or other income sources in Denmark.

Deadlines, penalties and practical tips

In Denmark, you are expected to update your registration data promptly. For address changes the deadline is typically 5 days, while tax-related changes should be updated as soon as you know that your income or situation for the year will differ significantly from your current preliminary assessment.

If you do not update your data in time, the authorities may:

To keep your registration data in Denmark accurate and avoid problems:

Correct and up-to-date registration data is the foundation for efficient tax planning, legal compliance and smooth access to Danish public services for both individuals and businesses.

Deregistration from Denmark when leaving the country and its tax consequences

When you move away from Denmark, you must deregister properly to avoid unnecessary tax, social security and administrative problems. Deregistration affects your CPR registration, tax residence status and, in some cases, your obligations towards Danish social security and unemployment insurance.

When you must deregister from Denmark

You are generally required to deregister your address in Denmark if you plan to live abroad for more than 6 months. In practice, you must report your move to the municipality (Folkeregisteret) no later than 5 days after leaving the country. If you keep a home in Denmark that is available for your use at any time, the Danish Tax Agency (Skattestyrelsen) may still consider you fully or limited tax liable, even if you deregister your address.

Deregistration is done via the national registration system (Folkeregister) in your municipality, usually through the online self-service solution using MitID. If you cannot use MitID, you can deregister in person at the Citizen Service (Borgerservice) or by sending the required forms.

Tax residence when leaving Denmark

For tax purposes, leaving Denmark does not automatically end your Danish tax liability. The key questions are whether you:

If you give up your home in Denmark and move abroad permanently, you normally cease to be fully tax liable in Denmark from the date you move. However, you may remain limited tax liable on certain Danish-source income, for example salary for work performed in Denmark, board fees, pensions, or rental income from Danish property.

If you keep a house or apartment in Denmark that is at your disposal, the tax authorities can still treat you as fully tax resident, even if you spend most of your time abroad. In such cases, double tax treaties between Denmark and your new country of residence determine where you are considered tax resident and which country has the primary right to tax your income.

Final tax assessment when you move

In the year you leave Denmark, you are taxed as a resident for the period up to the date you cease to be fully tax liable, and as a non-resident for the rest of the year. You must submit a Danish tax return for the year of departure, declaring:

Denmark uses a progressive income tax system. As a resident, your income is subject to:

When you leave, you still benefit from the personal allowance for the part of the year you are tax resident. The personal allowance for adults is around DKK 49,700 per year; if you are resident only part of the year, the allowance is normally prorated based on the number of months you are resident.

After your departure, the Danish Tax Agency issues a final tax assessment (årsopgørelse) once your tax return is processed. You may receive a tax refund or an additional tax bill. It is important to keep your e-Boks and bank account active until the final settlement is completed.

Exit tax on shares and certain assets

If you own shares or certain financial assets when you move away from Denmark, you may be subject to Danish exit tax (fraflytterbeskatning). Exit tax can apply if:

In such cases, Denmark may tax unrealised capital gains on your shares as if you had sold them on the day you cease to be fully tax resident. You can usually apply for deferral of payment of exit tax if you move to another EU/EEA country and meet specific conditions, such as providing security in some situations and filing annual information about your portfolio.

Exit tax rules are complex and depend on your asset types, holding period, double tax treaties and your new country of residence. Professional advice is strongly recommended if you hold significant investments, shares in your own company or employee share schemes when leaving Denmark.

Deregistration and social security

When you deregister from Denmark and move abroad, your coverage under the Danish public health system and other social security schemes usually ends from the date of departure, unless you are posted abroad by a Danish employer and remain covered under EU or bilateral social security rules.

Key points to consider:

If you receive Danish public benefits (for example unemployment benefits, certain family benefits or social assistance), these are usually stopped when you move abroad, unless specific EU or treaty rules allow export of the benefit.

Property, rental income and limited tax liability

If you keep property in Denmark after moving abroad, you may remain limited tax liable in Denmark. Typical situations include:

Rental income from Danish property is taxable in Denmark, even if you live abroad. You must file a Danish tax return and declare the rental income, deducting allowable expenses such as maintenance, property tax and mortgage interest. The tax is calculated according to the rules for limited tax liability, and double tax treaties usually give Denmark the primary right to tax income from Danish real estate.

Practical steps when deregistering

  1. Deregister your address with the municipality via online self-service or Borgerservice
  2. Update your contact details in e-Boks and with the Danish Tax Agency so you receive all letters and tax assessments
  3. Inform your employer, A-kasse, pension providers and insurance companies about your move
  4. Check whether exit tax rules apply to your investments and whether you need to submit special forms
  5. Submit your final Danish tax return for the year of departure and any subsequent years in which you have Danish-source income

How professional accounting support can help

Deregistration from Denmark and the related tax consequences are often more complex than they appear, especially if you:

A specialised Danish accounting firm can help you determine your exact tax residence status, calculate your final tax, assess any exit tax, and ensure that all registrations and deregistrations are done correctly. This reduces the risk of double taxation, late payment interest and penalties, and helps you start your life in the new country with a clear and compliant tax position.

The step-by-step process of online re-registration

The process of applying for a Danish re-registration can be divided into 8 basic steps:

Logging in to the website: Start by logging on to www.borger.dk using your NemID.

2. Selecting the appropriate category: On the left menu bar, click “Bolig og flytning” and then select “Flytning.” Then go to “Når du skal flytte” and click “Anmeld flytning til folkeregistret.”

3. Start the process: To continue, click “Start.” Before you do so, make sure you select the correct municipality in the gray bar on the right, next to the login button.

5. Enter data about the current move: Enter who is moving and the CPR number of the spouse or partner, if family is also involved. Click “Næste.”

6. Entering a new address: Select the date of the move, enter the new address and click “Næste”. If the new address is not listed, check that you have selected the correct municipality.

7. Selecting a new doctor: On the next page you have the option to select a new doctor. Click “Skift læge” and on the map and the list of available medical practices in the new location, select the appropriate doctor by clicking “Vælg” next to his name and then “Næste.”
