Opening a sole proprietorship in Denmark

Enkeltmandsvirksomhed, or sole proprietorship, is the simplest form of doing business in Denmark, often chosen by people from abroad. It is an excellent solution for those who are just starting out as entrepreneurs or do not have a lot of financial resources.

Carefully reviewing the requirements, deadlines and required documents for the various legal forms of Danish businesses is key before making a decision. It is also advisable to carefully analyze all the advantages and disadvantages so that you can make an informed choice that suits your expectations and capabilities.

Let us make it easy for you to start a Danish business.

Introduction to Enkeltmandsvirksomhed

Here is the key information about a sole proprietorship Enkeltmandsvirksomhed in Denmark:

- There is no requirement to raise share capital when starting a sole proprietorship in Denmark. This means that entrepreneurs starting a business in this form do not have to deposit a certain amount of money as initial capital, as is required for other legal forms of businesses, such as limited liability companies (ApS). This lack of a start-up capital requirement significantly simplifies the process of setting up a company, reducing the financial barrier and allowing those with fewer financial resources to get an easier start in business.

- The Danish administration offers support to the self-employed, helping them through the business registration process. As part of this support, entrepreneurs can count on information regarding required documents, registration procedures and all legal obligations related to running a business.

- Under Enkeltmandsvirksomhed, it is the founder who makes all decisions related to the management of the company and its operations. All responsibility for operations, strategy and day-to-day decisions lies in the hands of the owner. Nonetheless, the founder has the ability to delegate authority to others by granting them powers of attorney. Such powers of attorney allow these individuals to make decisions and act on behalf of the company in certain matters, which may include, for example, negotiating with customers, managing finances or representing the company in dealings with other institutions.

- A Danish sole proprietorship is a form of business in which the owner is personally liable for all financial obligations of the company. This means that all debts, both those arising from operations and tax liabilities, are directly attributable to the owner. In the event of financial problems or insolvency of the business, the owner is required to repay the debts from his own assets, which may include assets such as real estate or vehicles. This structure means that the owner's private assets can be used to cover the company's liabilities, which entails a higher financial risk for the entrepreneur.

- Those who relocate to Denmark have the option of registering their business with Erhvervsstyrelsen, the Agency for Business Activity and Enterprise, which is part of the Danish Ministry of Economic Affairs. This is the institution responsible for overseeing economic activity in the country. Registration with Erhvervsstyrelsen ensures the legality of the operation and allows you to take advantage of the various forms of support and administrative services offered by the Danish government.

Why start a sole proprietorship in Denmark?

One of the main advantages of a sole proprietorship in Denmark is its simplicity in management. Running such a company is much less complicated compared to larger forms of business, making it possible for young entrepreneurs, often without much business experience, to run their business effectively without the need for sophisticated management tools.

Another important advantage is the low cost of setting up a business, amounting to only 10,000 Danish kroner, which, converted into zlotys, is a little over 6,000. The low financial entry threshold makes setting up a business in Denmark accessible to a wide range of entrepreneurs, which further increases the attractiveness of this form of business.

One of the biggest conveniences for those considering starting a sole proprietorship in Denmark is that there is no requirement to raise share capital. Unlike other legal forms where share capital is required, Enkeltmandsvirksomhed allows you to start a business without having to commit a lot of money at the start.

Tax on business income in Denmark is taxed on a single tax return. This means that the entrepreneur declares the income earned from the business in his or her personal tax return, which simplifies the tax settlement process and ensures that the income is taxed only once.

In addition, it is possible to grant power of attorney to others who can act on behalf of the company. This is particularly useful in situations where the business owner needs support in managing or conducting certain business operations.

It is also worth noting that a sole proprietorship in Denmark does not have to be registered for VAT if the annual income does not exceed DKK 50,000. This allows entrepreneurs whose business generates less income to avoid additional administrative and financial burdens related to VAT settlements.

How to start a Danish sole proprietorship (Enkeltmandsvirksomhed)?

Registering a sole proprietorship in Denmark, known as Enkeltmandsvirksomhed, is quite easy. In order to register this type of business, it is helpful to know the following steps to follow. The process is relatively simple and consists of several steps.

I. Preparing all the necessary information before starting to register a sole proprietorship in Denmark is crucial. Make sure you have the following data gathered:
- Company name - You must specify the name under which your business will operate. In Denmark, it is important that the name be unique and not already used by another registered company.
- Company Address - Prepare the exact address of your company's registered office in Denmark. This can be the place where the business will be physically conducted, such as an office, or a home address if the business is conducted from home. In case you don't need a Danish registered office, for example, when running an online business, you can also use a virtual office service to get a Danish address for your company.
- PKD code - Choose the PKD code that best describes the type of business you intend to conduct. This code is valid for business classification purposes.
- CPR number - Prepare your CPR number (Central Registration Number), which is the Danish identification number for individuals.

II. Registration of a sole proprietorship in Denmark is done online using Virk.dk. To start the process, you need to fill out a registration form available on this platform. This form requires detailed information about the company, such as its name, address, PKD code and CPR number. Once you have completed all the required data, you need to validate the form, which will allow it to be automatically sent to the relevant business registration offices in Denmark. The entire process is convenient and efficient, as it eliminates the need to submit documents in person to the authorities, speeding up the establishment of a sole proprietorship in Denmark.

III. After submitting the registration form through Virk.dk, your company will receive a CVR number, which is a key identification element for companies in Denmark. The CVR number, or Central Business Register, acts as a unique identifier for your company, which will be used in all official business-related documents and procedures - it is required for activities such as opening a bank account in the company's name, filing tax returns, obtaining licenses and permits, and for all dealings with public and commercial institutions.

IV. If you expect your company's annual turnover to exceed DKK 50,000, you will be required to register as a VAT payer. This registration can be done directly through Virk.dk, which simplifies the entire process. To begin registration, log into your Virk.dk account. Then search for the VAT registration form, which is available on the platform. Once you have found the form, fill in all the required information about your company and your expected turnover. After completing the form, submit it electronically through the portal. After submitting the VAT registration form, you will receive a registration confirmation, and your company will be registered as a VAT payer. You will be required to comply with applicable tax regulations, including issuing invoices at the appropriate VAT rate and filing regular tax returns.

Handling VAT registration and compliance through Virk.dk can be complex and time-consuming. By working with a Danish tax representative, you can streamline the entire process, from registration to ongoing compliance. Let an expert manage your VAT obligations, ensuring accurate filings and freeing you to focus on what you do best-growing your business.

V. Opening a separate bank account for your business is a key step that will help you effectively manage your company's finances. Having a dedicated account makes it easier not only for day-to-day operations, but also for organizing and controlling your cash flow, which is important for the proper running of your business. You will need to provide company registration documents, such as a CVR number, as well as other required documents proving your identity and the legal status of your company. Having a separate bank account allows you to separate your personal and business finances, which simplifies bookkeeping and tax preparation.

VI. Keeping accounts in accordance with Danish regulations is an essential part of managing Enkeltmandsvirksomhed. It is worth ensuring that all financial operations are properly documented and in accordance with applicable regulations. If you have the requisite accounting skills and knowledge, you may choose to do your own bookkeeping. Alternatively, if you don't feel confident in bookkeeping or prefer to focus on other aspects of running your business, you can use the services of a professional accounting firm. Working with such an office can help you manage your finances, prepare tax returns, and ensure that all your books are kept in accordance with Danish regulations.

VII. Regular tax reporting and filing is a key responsibility for any company operating in Denmark. To ensure compliance with the requirements of the Danish Tax Authority (SKAT), it is important that you follow the established deadlines and procedures.

Legal and tax registration requirements for sole proprietors in Denmark (CVR, SKAT, NemID/MitID)

Before you can legally run a sole proprietorship (enkeltmandsvirksomhed) in Denmark, you must register your business and yourself with the relevant Danish authorities. The key elements are your CVR number, tax registration with Skattestyrelsen (SKAT), and access to digital self‑service via NemID/MitID and associated mailboxes.

Registering your sole proprietorship and obtaining a CVR number

Every active business in Denmark must have a CVR number (Central Business Register number). This is your company’s official ID used for invoices, contracts, tax, VAT and communication with public authorities.

You register your sole proprietorship online via Virk.dk. The registration is free and normally processed quickly. During registration you will need to provide:

• Personal information (CPR number, address, contact details)
• Business name and any secondary names
• Business address (can be your home address if allowed by local rules)
• Business activity (NACE code / branchekode)
• Expected start date of business activity
• Information on expected turnover and whether you need VAT registration from day one

Once approved, you receive your CVR number, which must be shown on invoices, your website (imprint), and other business documents.

Tax registration with Skattestyrelsen (SKAT)

A sole proprietorship is not a separate taxpayer in Denmark. Business profits are taxed as your personal income, but you must still register the business for tax purposes with Skattestyrelsen.

As part of the Virk.dk registration, you indicate:

• That you are starting self‑employment (selvstændig erhvervsdrivende)
• Expected annual profit or loss from the business
• Whether you want to pay preliminary tax (B‑skat) on account during the year

Based on your estimates, Skattestyrelsen sets your preliminary tax (forskudsskat). You pay B‑tax in monthly instalments, typically 10 times a year. If your income changes significantly, you should update your preliminary assessment to avoid large underpayments or overpayments.

Business profits are taxed under the Danish personal income tax system. As a guideline, the combined marginal tax rate on personal income (including labour market contribution) can reach around 52–56% depending on your municipality and church tax. There is also a top tax (topskat) on personal income above a certain threshold, and a separate tax on positive capital income.

NemID/MitID and digital mailboxes

To handle your registrations and ongoing obligations, you must be able to log in to public self‑service solutions. Denmark is in the process of replacing NemID with MitID, and most new setups are based on MitID.

As a sole proprietor you typically need:

• MitID (or NemID) as a private person, used to log in to Skat.dk, Virk.dk and other portals
• Digital Post (e‑Boks or another approved provider) for official letters from authorities
• e‑Boks for businesses linked to your CVR number, so your company can receive digital mail

Most communication from Skattestyrelsen and other authorities is digital only. Missing a message in Digital Post does not stop deadlines from running, so it is important to check it regularly or set up notifications.

VAT (Moms) registration threshold and timing

When registering your sole proprietorship, you must decide whether to register for VAT (moms). In Denmark, you are obliged to register for VAT if your taxable turnover exceeds, or is expected to exceed, 50,000 DKK within any 12‑month period.

Key points:

• If you expect to exceed 50,000 DKK in turnover within 12 months, you must register for VAT before you start invoicing with VAT.
• If you stay below the threshold, VAT registration is voluntary, but once registered you must charge VAT and submit VAT returns according to the assigned period.
• Most services and goods are subject to 25% VAT, with specific exemptions (for example certain financial and health services).

VAT registration is done through the same Virk.dk form when you register your business or later via changes to your registration. Your VAT number is the same as your CVR number.

Registration for employer obligations (A‑tax, AM‑bidrag)

If you plan to hire employees in your sole proprietorship, you must register as an employer. This is also done via Virk.dk. As an employer you are responsible for:

• Withholding A‑tax (income tax) from employees’ salaries
• Withholding labour market contribution (AM‑bidrag) of 8% from gross salary
• Reporting salaries and withholdings monthly via eIndkomst

Failing to register as an employer before paying salaries can lead to penalties and interest, so the registration should be completed before you hire staff.

Deadlines and ongoing reporting duties

After registration, you must comply with several ongoing reporting and payment obligations:

• VAT returns: New small businesses are often assigned quarterly VAT periods. VAT must be reported and paid no later than one month and 10 days after the end of the period (for example, VAT for January–March must typically be reported and paid by mid‑May). Larger businesses may have monthly periods, while some very small businesses may have half‑yearly periods.
• Income tax: You must file your annual tax return (årsopgørelse/udvidet selvangivelse) with business income details. The deadline for self‑employed individuals using the extended return is usually later than for employees only, and electronic filing is mandatory.
• Preliminary tax (B‑skat): B‑tax instalments must be paid on the due dates set out in your preliminary assessment. Voluntary extra payments can reduce interest on underpaid tax.

Registration for other schemes and industry‑specific requirements

Depending on your activity, additional registrations may be required, for example:

• Excise duties (afgifter) for certain goods
• Environmental or sector‑specific permits
• Registration with industry authorities or professional boards

These are not part of the basic CVR and tax registration, but they are essential for operating legally in certain sectors.

Because the Danish registration system is highly digital and interconnected, setting up your CVR, tax registration and MitID correctly from the start will make it much easier to manage VAT, income tax and employer obligations as your sole proprietorship grows.

Choosing the right tax scheme: B-income, virksomhedsskatteordningen (VSO) and capital returns scheme

One of the first strategic decisions for a Danish sole proprietor is choosing how your business income will be taxed. In Denmark, self-employed income is typically treated as B‑income, and you can optionally use the business tax scheme (virksomhedsskatteordningen – VSO) or the capital returns scheme (kapitalafkastordningen). The right choice affects how much tax you pay, when you pay it, and how much you can reinvest in your business.

What is B‑income for sole proprietors?

As a sole proprietor, your profit is normally taxed as B‑income. This means:

• Your business profit is added to your personal income and taxed under the progressive Danish income tax system.
• You do not have an employer withholding A‑tax; instead, you pay tax via preliminary tax (B‑tax) in instalments during the year.
• You pay:
  • Municipal tax (typically around 24–27% depending on municipality)
  • Health contribution via municipal tax (included in the municipal rate)
  • Bottom‑bracket state tax of 12.09% on personal income above the personal allowance
  • Top‑bracket state tax of 15% on personal income above the top‑tax threshold (around DKK 588,900 in 2024 before labour market contribution)
  • Labour market contribution (AM‑bidrag) of 8% on most business income

Business expenses are deducted before calculating your taxable profit. With “plain” B‑income (without VSO or the capital returns scheme), all profit is treated as personal income in the year it is earned. You cannot keep profits taxed at a lower business rate; everything is taxed as if it were withdrawn to you personally.

Business tax scheme (VSO – virksomhedsskatteordningen)

The business tax scheme (VSO) is a voluntary scheme for self‑employed individuals and certain partnerships. It allows you to separate the business economy from your private economy and to defer tax on part of your profit.

Key features of VSO:

• Separation of business and private finances: You keep a separate business account and prepare a business statement with specific VSO calculations.
• Possibility to retain profit in the business: Part of the profit can be kept in the business and taxed at a business tax rate of 22% (aligned with the corporate tax rate), instead of being fully taxed as personal income immediately.
• Tax deferral: You only pay full personal income tax when you withdraw the retained profit from the business to yourself.
• Interest and financing advantages: Interest expenses and income can be handled more flexibly within the scheme, which can reduce your total tax if you have loans or significant assets in the business.

When VSO is beneficial:

• Your business generates stable or high profits, and your total income would otherwise push you into the top‑tax bracket.
• You want to reinvest profits in the business instead of withdrawing everything for private consumption.
• You have or plan to have larger investments in equipment, property or other business assets.

Important conditions and obligations in VSO:

• You must keep separate accounts for business and private transactions and follow the detailed VSO bookkeeping rules.
• You must prepare a VSO statement each year as part of your tax return, showing:
  • Business profit
  • Withdrawals to you personally
  • Retained profit and calculated business tax (22%)
• Once you opt into VSO, you are expected to apply it consistently each year, unless you actively choose to leave the scheme and follow the rules for exiting.

VSO is powerful but complex. Incorrect use can lead to unexpected tax bills, especially when you withdraw large amounts or close the business. For many sole proprietors, it is advisable to involve an accountant when entering or leaving VSO.

Capital returns scheme (kapitalafkastordningen)

The capital returns scheme is a simpler alternative to VSO. It is also voluntary and aims to give a more balanced tax treatment of the return on capital invested in the business.

How the capital returns scheme works:

• You calculate a capital base (the value of business assets minus business liabilities) at the start of the year.
• You apply a capital return rate (set annually by the tax authorities) to this base to determine the “capital return”.
• This calculated capital return is then taxed as capital income instead of personal income.

Why this can be beneficial:

• Capital income is not subject to the 15% top‑bracket state tax in the same way as personal income, which can reduce your overall tax if you are close to or above the top‑tax threshold.
• The scheme is less complex than VSO and does not require the same level of separation between business and private finances.

Limitations of the capital returns scheme:

• You cannot defer tax on profits in the same way as in VSO; you do not get the 22% business tax on retained earnings.
• The effect is mainly relevant if you have a significant capital base (for example, property, machinery, or other assets financed with your own funds).
• The calculation of the capital base must follow specific rules, and mistakes can reduce or eliminate the expected benefit.

Comparing B‑income, VSO and the capital returns scheme

In practice, you are always taxed on B‑income as a sole proprietor. The question is whether you should add VSO or the capital returns scheme on top of the basic rules. A simplified comparison:

• Basic B‑income only:
  • All profit is taxed as personal income in the year earned.
  • Simple administration and bookkeeping.
  • Suitable for small businesses, side‑income or when profits are modest and relatively stable.
• VSO (business tax scheme):
  • Allows you to retain profit in the business taxed at 22% and defer full personal income tax until withdrawal.
  • Best suited for higher profits, reinvestment and long‑term growth.
  • Requires strict separation of business and private finances and more advanced accounting.
• Capital returns scheme:
  • Reclassifies part of the profit as capital income based on your capital base.
  • Can reduce top‑bracket tax if you have substantial capital invested.
  • Less complex than VSO but offers no real tax deferral.

How to choose the right tax scheme for your sole proprietorship

When deciding which scheme to use, consider:

• Level and stability of profit: Higher and more stable profits usually make VSO more attractive.
• Your total personal income: If your combined income (business + other income) approaches or exceeds the top‑tax threshold, VSO or the capital returns scheme can reduce your effective tax rate.
• Investment plans: If you plan to reinvest in equipment, vehicles, or property, VSO can help you keep more capital inside the business.
• Complexity vs. benefit: For small or part‑time businesses, the administrative burden of VSO may outweigh the tax savings.
• Risk and future plans: If you plan to convert to an ApS later, or to sell or close the business, the choice of scheme affects the tax consequences at that time.

Because the rules for VSO and the capital returns scheme are detailed and the optimal choice depends on your full financial situation, many sole proprietors in Denmark choose to discuss the options with an accountant before making a decision. Proper planning from the start can prevent expensive corrections later and ensure that your tax scheme supports your long‑term business goals.

VAT (Moms) obligations for Danish sole proprietorships: registration thresholds, reporting and deadlines

In Denmark, VAT (moms) is a central part of running a sole proprietorship. Even if you are a small freelancer or a one‑person consulting business, you must understand when to register, how to charge VAT on your invoices and how to report and pay it to the Danish Tax Agency (Skattestyrelsen).

When must a Danish sole proprietorship register for VAT?

You must register your sole proprietorship for VAT when your taxable turnover exceeds DKK 50,000 within a 12‑month period. This is not a calendar year, but a rolling 12‑month period. As soon as you can reasonably foresee that you will cross this threshold, you are required to register.

The DKK 50,000 limit applies to most types of commercial activities, including consulting, IT services, trades, crafts, online shops and other typical self‑employed activities. Some activities are VAT‑exempt by law (for example certain health services, financial services and education), and for these you normally do not register for VAT even if your turnover is higher. In mixed activities, where part of your income is VAT‑liable and part is exempt, you may need a partial VAT registration and a proportional deduction of input VAT.

VAT registration is done via Virk.dk when you register or update your business in the CVR register. After registration, you will receive a VAT number (the same as your CVR number) and access to the VAT section in skat.dk, where you submit your VAT returns.

Standard VAT rate and how to charge VAT

Denmark has a single standard VAT rate of 25% on most goods and services. There are no reduced VAT rates for specific sectors (such as food or transport) as in some other EU countries. Instead, some areas are fully exempt from VAT.

As a VAT‑registered sole proprietor, you must:

• Charge 25% VAT on all VAT‑liable sales to Danish customers (B2B and B2C), unless a specific exemption applies
• Issue invoices that clearly show the net amount, VAT amount and total amount, as well as your CVR number
• Keep proper documentation for all sales and purchases, including electronic invoices and receipts

For cross‑border services and goods within the EU, special rules apply (for example reverse charge for B2B services, distance sales rules for B2C). These rules can significantly affect whether you charge Danish VAT, foreign VAT or no VAT on a given invoice, so it is important to clarify your typical customer base and transaction types before you start invoicing.

Input VAT: what you can deduct

Once registered, you can deduct input VAT (købsmoms) on business‑related purchases from the VAT you collect on your sales. This includes, for example:

• Office rent and utilities
• IT equipment, software and subscriptions
• Tools, materials and stock
• Professional services (accounting, legal, marketing) with VAT

Some costs are only partially deductible or not deductible at all, such as certain car expenses, representation and mixed private/business expenses. You must be able to document that the expense is related to your business activity and keep all invoices for at least five years.

VAT reporting periods for sole proprietorships

Your reporting frequency depends on your annual turnover. For most new and smaller sole proprietorships, VAT is reported quarterly. The main thresholds are:

• Annual turnover up to DKK 5 million: quarterly VAT reporting
• Annual turnover above DKK 5 million: monthly VAT reporting

Some very small businesses may be placed on half‑yearly reporting, but this is less common and depends on Skattestyrelsen’s current practice. Your reporting frequency will be stated in your VAT registration and visible in your tax calendar on skat.dk.

Deadlines for filing and paying VAT

VAT must be both reported and paid by the statutory deadlines. For quarterly reporting, the deadlines are typically one month and 10 days after the end of the quarter. For example, VAT for the first quarter must normally be reported and paid in early May. For monthly reporting, the deadline is usually one month and 10 days after the end of the month.

The exact dates can change slightly from year to year, so you should always check your personal VAT calendar on skat.dk. Missing a deadline may result in:

• Automatic estimated VAT assessments by Skattestyrelsen
• Interest and surcharges on late payments
• Administrative fines for repeated non‑compliance

Payment is typically made via online banking using the payment ID shown when you submit your VAT return. It is your responsibility to ensure that the payment reaches Skattestyrelsen on time.

How to file your VAT return in practice

VAT returns are submitted digitally via skat.dk. You must report:

• Total VAT‑liable sales (excluding VAT)
• Total VAT on sales (output VAT)
• Total deductible VAT on purchases (input VAT)

The system then calculates whether you must pay VAT to Skattestyrelsen or receive a VAT refund. Many sole proprietors use accounting software that integrates with the Danish tax system and automatically prepares VAT figures based on their bookkeeping. This reduces the risk of errors and saves time.

Voluntary VAT registration and special situations

In some cases, you may choose to register for VAT before reaching the DKK 50,000 threshold, for example if you have significant start‑up costs and want to deduct the input VAT. Voluntary registration is possible for certain types of activities, such as property rental or specific projects, but is subject to detailed rules.

If you change your business model, start selling abroad, or move from VAT‑exempt to VAT‑liable services, you may need to update your VAT registration. Similarly, if you close or suspend your sole proprietorship, you must deregister for VAT and submit a final VAT return.

Why correct VAT handling matters for your sole proprietorship

Correct VAT registration, invoicing and reporting is crucial for avoiding unnecessary tax risks and penalties. For many sole proprietors, VAT is one of the most complex and time‑consuming compliance areas, especially when combined with cross‑border trade or mixed VAT‑exempt and VAT‑liable activities.

A Danish accounting firm can help you assess whether and when you must register for VAT, set up your invoicing and bookkeeping correctly, choose suitable accounting software and ensure that your VAT returns are filed on time and in line with current Danish rules.

Social security, ATP and pension considerations for self‑employed in Denmark

When you run a sole proprietorship in Denmark, you are generally treated as self‑employed for social security purposes. This means you are not automatically covered in the same way as an employee, and you must actively ensure that your social security, ATP and pension needs are taken care of.

Public social security for self‑employed in Denmark

Denmark has a tax‑financed welfare system, and as a self‑employed person you are covered by most public benefits on almost the same terms as employees, as long as you are fully tax resident and pay Danish tax and labour market contributions (AM‑bidrag).

Key elements include:

• Health care: Access to the public health system is based on residence and registration with the Civil Registration System (CPR), not on employment status. As a self‑employed person you have the same right to a general practitioner and hospital treatment as employees.
• State pension (folkepension): You earn the right to the Danish state pension by living in Denmark. Full state pension normally requires 40 years of residence between age 15 and the state pension age. Your business income does not in itself generate extra state pension, but it affects whether you receive income‑tested supplements.
• Sickness benefits (sygedagpenge): Self‑employed can receive sickness benefits from the municipality, but the waiting period and conditions differ from employees. As a rule, you can receive benefits after 2 weeks of documented sickness, provided you have run your business for at least 6 months within the last 12 months, including the last month before you became ill.
• Maternity and paternity benefits (barselsdagpenge): Self‑employed have access to parental benefits if you meet the income and activity requirements and have been active in your business for a certain minimum period before the leave.

Because benefits for self‑employed are often lower and start later than for employees, many sole proprietors choose voluntary schemes to improve their coverage.

ATP (Arbejdsmarkedets Tillægspension) for self‑employed

ATP is a mandatory labour market supplementary pension for employees in Denmark. Contributions are normally shared between employer and employee and are based on hours worked. As a self‑employed person you are not automatically covered by ATP through your sole proprietorship.

You may, however, be covered by ATP if:

• you also have a regular employment alongside your business where ATP is paid, or
• you pay voluntary ATP contributions under specific schemes (for example in connection with certain unemployment insurance funds or collective agreements).

ATP contributions are relatively modest compared to private pension savings, but they provide a lifelong, guaranteed supplementary pension on top of the state pension. If you are only self‑employed and not paying ATP in any other way, it is important to compensate with your own pension savings.

Voluntary insurance for sickness and maternity

To reduce the financial risk of illness or maternity leave, self‑employed in Denmark can sign up for voluntary public insurance schemes. These are administered via the municipality and Udbetaling Danmark.

The two most common options are:

• Voluntary sickness benefit insurance: Allows you to receive sickness benefits from the first or third day of sickness instead of after 2 weeks. You pay a fixed annual premium, which depends on the chosen coverage level and your average income from self‑employment.
• Voluntary maternity/paternity insurance: Can improve your entitlement to benefits during maternity and parental leave if your business income fluctuates or is low in some years.

Premiums are tax‑deductible as business expenses if the insurance is directly related to your activity as a sole proprietor. Whether these schemes are worthwhile depends on your income level, family situation and risk tolerance.

Pension savings for self‑employed sole proprietors

Unlike employees, self‑employed do not have an employer who pays into a company pension scheme. You must therefore plan and finance your own pension savings. In practice, most Danish sole proprietors use one or a combination of the following pension products:

• Rate pension (ratepension): Savings are paid out in instalments over a fixed period (typically 10–30 years). Contributions are deductible up to a relatively high annual limit, which is adjusted regularly. The deduction is taken in your personal income.
• Annuity pension (livrente): Provides lifelong payments from retirement. There is no fixed upper limit on deductible contributions, which makes annuity pensions attractive for high‑income self‑employed who want to reduce top‑bracket tax.
• Old‑age savings (aldersopsparing): Contributions are not tax‑deductible, but payouts are tax‑free. There is an annual contribution cap. This product is often used to supplement other pension schemes and to avoid affecting income‑tested benefits in retirement.

Contributions to pension schemes can be paid either privately or directly from your sole proprietorship. If you use the business tax scheme (virksomhedsskatteordningen, VSO), pension contributions can be part of your tax optimisation strategy, because you can shift income between years and tax brackets.

How much should a self‑employed person save for pension?

There is no legal minimum pension contribution for self‑employed in Denmark. A common rule of thumb is to save at least 15–20% of your gross income for retirement if you start in your 30s or 40s and expect to rely mainly on your own savings plus the state pension.

When deciding your pension level, consider:

• your expected long‑term business income
• whether you are covered by ATP or other labour market pensions from previous or parallel employment
• your age and how many years you have until retirement
• your risk tolerance and investment horizon
• whether you plan to sell your business or other assets to finance retirement

Because pension contributions are often tax‑deductible, there is a direct link between pension planning and your overall tax strategy as a sole proprietor.

Unemployment insurance (A‑kasse) and day‑to‑day security

Unemployment insurance is not part of the public social security system, but it is crucial for many self‑employed. Membership in an unemployment insurance fund (A‑kasse) is voluntary and requires a monthly contribution.

As a self‑employed person you can:

• join an A‑kasse that accepts self‑employed members, and
• qualify for unemployment benefits (dagpenge) if your business closes or your income falls below certain thresholds, provided you meet the membership and income requirements.

Rules for self‑employed in A‑kasse are more complex than for employees, especially when it comes to documenting income and closing or suspending the business. It is important to clarify these conditions early, so you know what protection you actually have if your business fails.

Practical steps for securing your social and pension situation

When you open a sole proprietorship in Denmark, it is wise to address social security and pension from the start instead of waiting until your income grows. Consider the following steps:

1. Clarify whether you are considered self‑employed or an employee for each of your income sources, as this affects ATP, benefits and pension options.
2. Assess your need for voluntary sickness and maternity insurance based on your financial buffer and family situation.
3. Decide on a realistic annual pension contribution and choose suitable pension products (rate pension, annuity pension, old‑age savings).
4. Review whether membership of an A‑kasse and a trade union or professional association makes sense for your industry.
5. Coordinate your pension and insurance planning with your tax strategy, especially if you use VSO or other special tax schemes.

A Danish accounting firm familiar with self‑employed and sole proprietorships can help you calculate optimal pension contributions, ensure that premiums and contributions are booked correctly, and coordinate your social security planning with your tax and cash‑flow situation.

Employer obligations if you hire staff in your sole proprietorship (contracts, holiday pay, insurance)

When your Danish sole proprietorship grows and you decide to hire employees, you move from being only self‑employed to also being an employer. This brings a number of legal, tax and HR obligations that apply even if you only hire one part‑time person. Understanding these rules from the start helps you avoid fines, disputes and unexpected costs.

Registering as an employer (eIndkomst, eIndberetning)

Before you pay any salary, you must register as an employer with the Danish Tax Agency (SKAT) via Virk. Once registered, you get access to the eIndkomst system, where you report salary, tax and social contributions for each employee every time you pay wages.

As an employer you are responsible for:

• Withholding A‑tax (income tax) and labour market contribution (AM‑bidrag) of 8% from employee salaries
• Paying these amounts to SKAT by the statutory deadlines (usually the 10th or 17th of the following month, depending on your reporting frequency)
• Reporting all salary details (gross pay, benefits, holiday pay, pension etc.) to eIndkomst for each pay period

Employment contracts and working conditions

Danish employment law requires clear documentation of the employment relationship. If an employee works on average at least 3 hours per week over 4 consecutive weeks, you must provide written information about the terms of employment.

The contract or employment letter should at minimum state:

• Employer and employee details
• Workplace and job title or job description
• Start date and, if relevant, end date (for fixed‑term contracts)
• Working hours (full‑time/part‑time, weekly hours, schedule or reference to shift plan)
• Salary, payment frequency and any bonuses, commission or benefits
• Holiday rights and how holiday pay is handled
• Notice periods and probation period, if any
• Reference to any applicable collective agreement (overenskomst), if you are covered by one

Even if you are not bound by a collective agreement, you must comply with mandatory Danish rules on working time, rest periods, discrimination, equal treatment and health and safety.

Working time, minimum standards and HR policies

Under Danish and EU rules, employees are generally entitled to:

• Maximum average working time of 48 hours per week over a reference period
• At least 11 consecutive hours of rest per 24‑hour period
• At least one day off per week, normally Sunday

There is no statutory national minimum wage in Denmark, but many sectors are covered by collective agreements that set minimum pay, supplements for evening/weekend work, overtime rules and pension contributions. Even without a collective agreement, you should offer a competitive and reasonable salary to avoid disputes and recruitment problems.

Holiday entitlement and holiday pay (feriepenge)

Employees in Denmark earn holiday according to the Danish Holiday Act (Ferieloven). The main rules are:

• Employees earn 2.08 days of paid holiday for each month of employment, corresponding to 25 days (5 weeks) per holiday year when working full‑time
• Holiday is earned and can be taken on a concurrent basis within the same holiday year

How you handle holiday pay depends on whether the employee receives a fixed monthly salary or is paid by the hour:

• Monthly‑paid employees: They usually receive their normal salary during holidays. In addition, they are often entitled to a holiday supplement of at least 1% of the holiday‑qualifying salary for the year, paid once a year or when holiday is taken.
• Hourly‑paid employees: They typically do not receive salary during holidays, but instead earn holiday pay equal to 12.5% of their holiday‑qualifying salary. This holiday pay is usually reported and paid to FerieKonto or another approved holiday scheme.

As an employer you must calculate, report and pay holiday pay correctly and on time. Incorrect handling of holiday pay is one of the most common and costly mistakes for small Danish businesses.

Mandatory social contributions and ATP

In addition to withholding tax and AM‑bidrag from employees’ salaries, you must pay certain employer contributions. The most important is ATP (Arbejdsmarkedets Tillægspension), the statutory labour market supplementary pension.

ATP contributions are split between employer and employee. For a full‑time employee (at least 117 hours per month), the total ATP contribution per month is fixed, with approximately two‑thirds paid by the employer and one‑third by the employee. For part‑time employees, the ATP contribution is lower and depends on the number of hours worked.

You report and pay ATP together with other labour market contributions through the relevant reporting systems. Failure to pay ATP can lead to arrears, interest and penalties.

Occupational injury insurance and other insurances

If you hire employees in Denmark, you must take out occupational injury insurance (arbejdsskadeforsikring) with an approved insurance company. This insurance covers employees in case of work‑related accidents and occupational diseases.

In addition, many employers choose to take out:

• Employer’s liability insurance (arbejdsgiveransvarsforsikring) to cover claims if an employee causes damage while working
• Business liability insurance (erhvervsansvarsforsikring) to protect the company against claims from customers or third parties
• Health or accident insurance as an employee benefit, depending on the sector and competition for labour

Insurance requirements and best practices vary by industry, so it is important to assess your risk profile and ensure adequate coverage before employees start working.

Payroll, tax withholding and reporting

Running payroll correctly is a central obligation for any Danish employer. Each pay period you must:

• Calculate gross salary, overtime, allowances and benefits in kind
• Withhold AM‑bidrag (8%) and A‑tax according to the employee’s tax card (skattekort)
• Calculate and withhold employee contributions to ATP and any pension schemes
• Calculate employer contributions (ATP, pension, other agreed contributions)
• Report all data to eIndkomst and pay the withheld amounts and employer contributions to SKAT and relevant institutions by the deadlines

Using payroll software or an accountant familiar with Danish rules significantly reduces the risk of errors and penalties.

Pension schemes and other employee benefits

Outside collective agreements, there is no general legal obligation for a sole proprietor to offer a pension scheme. However, many employers provide a labour market pension where the employer pays a fixed percentage of salary (for example 8%) and the employee contributes their own share (for example 4%).

Offering pension, health insurance, paid lunch breaks or flexible working conditions can make your sole proprietorship more attractive as an employer and help you retain qualified staff.

Health and safety (arbejdsmiljø)

As soon as you have employees, you are responsible for providing a safe and healthy working environment in accordance with Danish health and safety legislation. This includes:

• Assessing and managing physical and psychological risks at the workplace
• Providing necessary safety equipment and training
• Ensuring that workstations, tools and processes comply with applicable standards

Depending on the size and nature of your business, you may also need to establish a formal health and safety organisation and carry out regular workplace assessments (APV).

Data protection and employee information

When you hire staff, you process personal data such as CPR numbers, salary information, health data and performance records. You must comply with GDPR and Danish data protection rules, including:

• Collecting only the data you need for employment and payroll
• Storing data securely and limiting access
• Informing employees about how their data is processed
• Deleting or anonymising data when it is no longer needed, subject to statutory retention periods

Why compliance matters for sole proprietors

Even as a small sole proprietorship, you are subject to the same core employer obligations as larger Danish companies. Non‑compliance can lead to:

• Fines and interest from SKAT for incorrect or late reporting
• Claims for unpaid holiday pay, overtime or pension
• Higher insurance premiums or uncovered claims in case of accidents
• Damage to your reputation as an employer and business partner

Setting up correct contracts, payroll routines, insurance and HR policies from the beginning makes hiring staff in your Danish sole proprietorship safer and more predictable. An accountant or payroll specialist with experience in Danish employer rules can help you design a setup that complies with all legal requirements and supports the growth of your business.

Bookkeeping and accounting requirements for Enkeltmandsvirksomhed (documentation, software, retention)

Running an Enkeltmandsvirksomhed in Denmark comes with clear bookkeeping and accounting obligations. Even if you are a very small business, you must be able to document all income and expenses, keep orderly records and store them for the required period. Good bookkeeping is not only a legal requirement, but also the basis for correct tax, VAT and social contributions.

Basic bookkeeping obligations for Danish sole proprietors

As a sole proprietor you are required to keep accounts that give a true and fair view of your business. In practice this means you must:

• Record all business income and expenses on an ongoing basis
• Keep a clear separation between private and business transactions
• Be able to reconcile your records with bank statements and other documentation
• Prepare an annual statement of results (profit and loss) and an overview of assets and liabilities
• Provide information needed for your personal tax return and any VAT returns

Even if you are not required to submit full annual accounts to the Danish Business Authority, SKAT can request your underlying bookkeeping and documentation at any time. Poor or incomplete records can lead to estimated assessments, additional tax and possible penalties.

Documentation: what you must keep and how

Every transaction in your Enkeltmandsvirksomhed must be supported by documentation. Typical documents include:

• Sales invoices and receipts issued to customers
• Purchase invoices from suppliers (including online purchases)
• Bank statements and credit card statements
• MobilePay, Stripe, PayPal and other payment provider reports
• Contracts and agreements with customers, suppliers and freelancers
• Lease agreements (office, car, equipment)
• Payroll documentation if you have employees
• Loan agreements and interest statements

Invoices must contain specific information to be valid, especially if you or your customer are VAT registered. A proper invoice should include at least:

• Your business name and address
• Your CVR number (if registered)
• Customer’s name and address (and CVR if B2B)
• Unique, consecutive invoice number
• Invoice date and delivery date (if different)
• Clear description of goods or services
• Quantity and unit price
• Net amount, VAT rate and VAT amount (if applicable)
• Total amount payable

Documentation can be stored digitally. Scanned or photographed receipts are accepted if they are readable, complete and stored in a secure and structured way. You do not need to keep paper copies if the digital version is of sufficient quality and can be produced on request.

Retention periods and storage requirements

In Denmark, business records for an Enkeltmandsvirksomhed must generally be kept for at least 5 full calendar years after the end of the financial year they relate to. This applies to:

• Invoices and receipts
• Bank and payment provider statements
• Accounting records and ledgers
• Contracts and agreements
• VAT documentation and VAT returns
• Payroll records and holiday pay documentation (if you have employees)

For certain types of information (for example, employee-related data or long-term contracts) longer retention may be appropriate. Records must be stored in a way that ensures:

• They are protected against loss, damage and unauthorised access
• They can be presented to SKAT in Denmark within a reasonable time
• They remain readable throughout the retention period

You may store your accounting data and documents electronically on Danish or foreign servers, as long as you can provide full access to SKAT when requested.

Choosing accounting software for your Enkeltmandsvirksomhed

While very small businesses can technically keep manual records, using accounting software is strongly recommended. Modern systems help you comply with Danish rules and save time. When choosing software, consider whether it offers:

• Support for Danish VAT (moms) rules and rates
• Automatic invoice numbering and invoice templates with CVR and VAT details
• Bank integration for automatic import and reconciliation of transactions
• Support for MobilePay, payment cards and online payment gateways
• Digital storage of receipts (via app or upload)
• Reports for SKAT, VAT returns and your personal tax
• Possibility to give your accountant secure access

Popular solutions in Denmark include cloud-based systems that integrate with Danish banks and SKAT’s reporting requirements. For many sole proprietors, a simple subscription is enough and can be upgraded if the business grows or hires staff.

Cash vs. accrual accounting and financial year

Most small Enkeltmandsvirksomheder use a simple form of accrual accounting, where income and expenses are recognised when they are earned or incurred, not when cash is received or paid. This gives a more accurate picture of your results and is usually required if you have inventory, larger assets or more complex operations.

Your financial year will typically follow the calendar year, as this aligns with your personal tax year. In specific situations it can be possible to use a different financial year, but this should be coordinated with SKAT and your accountant to avoid complications.

Bank accounts and separation of business and private finances

Although a separate business bank account is not always legally mandatory for a sole proprietorship, it is strongly recommended and often required by banks. Clear separation between private and business finances makes bookkeeping easier and reduces the risk of errors in your tax and VAT reporting.

Ideally you should:

• Use a dedicated business account for all income and expenses
• Avoid paying private costs from the business account and vice versa
• Record any transfers between business and private as owner’s contributions or withdrawals

This structure also makes it easier for an accountant to review your records and for SKAT to understand your accounts if they carry out a check.

Bookkeeping frequency and reconciliation

To stay compliant and avoid year-end stress, you should update your bookkeeping regularly. Many sole proprietors in Denmark:

• Record income and expenses weekly or at least monthly
• Reconcile bank accounts with accounting records every month
• Check outstanding customer invoices and unpaid supplier bills regularly
• Prepare interim overviews of results and liquidity during the year

Regular reconciliation helps you detect missing invoices, double payments or bank fees and ensures that your VAT and tax calculations are based on correct data.

Interaction between bookkeeping, VAT and tax

Your bookkeeping is the foundation for all your reporting obligations. From your accounts you will derive:

• VAT (moms) payable or refundable for each reporting period
• Business profit to be included in your personal tax return
• Basis for any tax schemes you use (for example VSO or capital returns scheme)
• Information needed for ATP, holiday pay and other employer obligations if you have staff

Errors in bookkeeping can quickly lead to incorrect VAT returns or underpaid tax. SKAT can impose interest and surcharges on late or incorrect payments, so it is important that your accounting records are accurate and up to date.

When to involve a professional accountant

Many Danish sole proprietors choose to handle daily bookkeeping themselves and work with an accounting firm for setup, control and year-end tasks. Professional support is particularly valuable if:

• You are VAT registered and have many transactions
• You use special tax schemes such as VSO
• You have employees, cross-border activities or complex contracts
• You are unsure which costs are deductible and how to document them

An accountant can help you set up your chart of accounts, choose and configure software, establish routines for documentation and ensure that your bookkeeping meets Danish legal requirements. This reduces the risk of mistakes and frees up time to focus on running and growing your Enkeltmandsvirksomhed.

Deductible business expenses and typical tax optimizations for sole proprietors

Understanding which costs you can deduct is crucial for keeping your tax bill under control as a Danish sole proprietor. In Denmark, you are generally allowed to deduct expenses that are incurred solely to earn, secure and maintain your business income. Private or mixed private/business costs are either not deductible or only partly deductible.

General rules for deductible expenses

As a sole proprietor (enkeltmandsvirksomhed), you are taxed personally on your business profit. Your taxable profit is your business income minus allowable business expenses. To be deductible, an expense must:

• Have a clear and direct connection to your business activity
• Be properly documented with invoices, receipts or contracts
• Not be of a purely private nature

Always keep documentation for at least 5 years, as SKAT can request it in case of control.

Typical deductible business expenses in Denmark

Below are some of the most common deductible costs for Danish sole proprietors. Exact treatment can depend on your industry and setup, so it is wise to get individual advice.

Office, home office and premises

If you rent an office, workshop or warehouse, the rent and related operating costs are normally fully deductible. This includes:

• Rent and common charges (fællesudgifter)
• Electricity, heating, water and internet used for the business
• Cleaning and minor repairs

If you work from home, you may be able to deduct a proportion of your housing costs, but only if a clearly separated part of the home is used exclusively for business. In practice, this is often difficult to meet in apartments and shared spaces. Where the conditions are met, you can typically deduct a percentage of:

• Rent or mortgage interest
• Property tax (ejendomsskat) and utilities
• Insurance related to the business area

Equipment, tools and depreciation

Purchases of equipment and assets used in the business are deductible either immediately or through depreciation:

• Smaller tools and equipment with a short life and low value can often be expensed directly in the year of purchase.
• Larger assets (for example machines, computers, furniture, vehicles) are depreciated over time according to Danish tax rules.

For most movable business assets, you can use the declining-balance depreciation method with a maximum rate of 25% per year on the tax value of the asset pool. Low-value assets (typically up to around DKK 30,000 excluding VAT per item) can often be fully expensed in the year of purchase, provided they are solely used for business.

Car and transport costs

Car expenses are an area where many sole proprietors either lose deductions or take too much risk. You have two main options if you use a car for business:

• Business car (firmabil): The car is owned or leased by the business. You can deduct all business-related costs (fuel, insurance, repairs, green tax, depreciation or lease payments). Private use of the car then triggers taxation of a car benefit (fri bil) in your personal income, calculated on the car’s value according to Danish rules.
• Private car with mileage deduction: The car is privately owned, and you receive a tax-free mileage allowance from your business for documented business trips. You cannot then deduct the actual car costs in the business.

If you use a private car for business trips, you can use the official mileage rates per kilometre set by the Danish tax authorities. The rates are split into two levels per year per car (a higher rate up to a certain number of kilometres and a lower rate above that). You must keep a detailed logbook with date, purpose, route and kilometres for each trip.

Public transport, taxis and other travel costs related to client meetings, site visits or courses are normally deductible when they are directly linked to your business activity.

Travel, meals and representation

Business travel costs are deductible when the trip is necessary for your business (for example visiting clients, suppliers, trade fairs or training). Deductible costs include:

• Transport (plane, train, bus, taxi, car rental)
• Accommodation (hotel, Airbnb used for business)
• Reasonable additional meal and small expenses while travelling

When you travel for business, you can either deduct documented actual expenses or, if you meet the conditions, use the official per diem rates for meals and small expenses for business trips with overnight stays. Per diems are subject to daily maximums and can be reduced if the employer (your business) pays some meals directly.

Representation expenses (for example taking a client to a restaurant) are only partly deductible. In Denmark, you can normally deduct 25% of documented representation costs that have a clear business purpose. Purely private hospitality is not deductible.

Telephone, internet and IT

Business-related telephone, mobile subscriptions, internet and software are deductible. If you use the same phone or internet connection for both private and business purposes, you must split the cost and only deduct the business share. In practice, many sole proprietors choose to have separate business subscriptions to avoid discussions with SKAT.

Software subscriptions (for example accounting software, CRM, design tools, cloud storage) and domain/hosting costs for your business website are fully deductible when used for business.

Marketing, website and professional services

Expenses for marketing and sales are generally fully deductible, including:

• Website design, development and maintenance
• Online advertising (Google Ads, social media ads, banner ads)
• Printed materials (business cards, brochures, flyers, roll-ups)
• Participation in trade fairs, exhibitions and networking events

Professional fees paid to accountants, bookkeepers, lawyers and other advisors in connection with your ongoing business are also deductible. Fees related to establishing the business can in many cases be deducted as start-up costs.

Education, courses and memberships

Courses, seminars and continuing education that maintain or update your existing professional skills are usually deductible. Education that gives you a completely new qualification or changes your profession is typically not deductible as a business expense.

Membership fees to professional associations and trade organisations that are directly related to your business can be deducted. Purely private club memberships are not deductible.

Insurance and risk management

Business-related insurance premiums are deductible, for example:

• Professional liability insurance
• Business contents and inventory insurance
• Product liability insurance
• Occupational injury insurance if you have employees

Private insurance (home, private contents, private accident insurance) is not deductible, unless a clearly separated part is directly linked to the business and can be documented.

Pension contributions and social security

As a self-employed person in Denmark, you are responsible for your own pension savings. Pension contributions can provide both long-term security and tax benefits. You can typically deduct contributions to:

• Rate pension (ratepension) up to an annual ceiling per person
• Life annuity (livrente), usually without a fixed upper limit, as long as the contributions are reasonable in relation to your income

Contributions are usually deducted in your personal income, not directly in the business accounts, but they are an important part of your overall tax optimisation as a sole proprietor.

Interest, bank fees and financing

Interest on business loans and overdrafts, as well as bank fees related to your business account, are deductible. Interest on private loans (for example a private mortgage) is not a business expense, but can in some cases be deducted separately in your personal tax as capital income.

Choosing the right tax scheme for optimisation

Beyond individual deductions, your choice of tax scheme has a major impact on your total tax burden. Danish sole proprietors can choose between different ways of being taxed on their business income:

• Taxation as personal B-income (default)
• The business tax scheme (virksomhedsskatteordningen, VSO)
• The capital returns scheme (kapitalafkastordningen)

Under the standard B-income model, your profit is taxed as personal income with municipal tax, health contribution and state tax. If your total income is high enough to reach the top tax bracket, part of your income will be subject to top tax, which significantly increases the marginal tax rate.

The VSO scheme allows you to keep part of the profit in the business and have it taxed at the business tax rate (which corresponds to the corporate tax rate). Only the amount you withdraw for private use is taxed as personal income. This can be a powerful tool to:

• Smooth your income between good and bad years
• Reduce or avoid top tax in high-profit years
• Build up capital in the business for investment

The capital returns scheme is simpler than VSO and allows you to treat part of the profit as capital income instead of personal income, which can be beneficial in some situations, especially if you have interest expenses or a specific income structure.

VAT (moms) and deductions

If your sole proprietorship is VAT-registered, you can deduct input VAT on most purchases used for VAT-liable activities. This means you can reclaim the VAT you pay on goods and services used in your business, such as:

• Office supplies, equipment and inventory
• Professional services (accounting, legal, consulting)
• Marketing and advertising

Some expenses have restricted VAT deduction, for example representation and certain car-related costs. It is important to distinguish between what is deductible for income tax and what is deductible for VAT, as the rules are not identical.

Practical tips to optimise your tax position

To make the most of the available deductions and schemes as a Danish sole proprietor, consider the following:

• Separate business and private finances with a dedicated business bank account and, ideally, separate cards and subscriptions.
• Use accounting software that supports Danish tax and VAT rules and keeps your documentation organised.
• Plan larger investments and pension contributions with an eye on your expected annual profit and tax bracket.
• Keep detailed records for car use, travel and representation to avoid losing deductions in case of a tax audit.
• Review annually whether the standard B-income model, VSO or the capital returns scheme is most advantageous for your situation.

A Danish accounting firm can help you set up the right structure from the start, ensure that your expenses are correctly classified and documented, and continuously adjust your tax strategy as your business grows.

Differences between a sole proprietorship and an ApS (limited company) in Denmark

A Danish sole proprietorship (enkeltmandsvirksomhed) and a private limited company (Anpartsselskab, ApS) are the two most common forms for small businesses in Denmark. They differ significantly in terms of liability, tax treatment, capital requirements and administrative obligations. Understanding these differences helps you choose the structure that best fits your risk profile, growth plans and tax situation.

Legal structure and liability

In a sole proprietorship there is no legal separation between you and your business. You operate under your own CPR number, and you are personally and unlimitedly liable for all business obligations. This means that business debts, claims from suppliers or compensation claims can, in principle, be enforced against your private assets, including savings and property.

An ApS is a separate legal entity with its own CVR number and equity. As an owner (shareholder) you are generally only liable up to the amount you have invested in the company’s capital. Creditors normally cannot pursue your private assets, unless you have given personal guarantees or acted fraudulently. For activities with higher financial or contractual risk, an ApS typically offers significantly better protection of your private wealth.

Minimum capital and formation costs

A sole proprietorship has no minimum capital requirement. You can start immediately without paying in share capital, which makes it attractive for freelancers, consultants and very small businesses with limited risk.

To establish an ApS you must contribute a minimum share capital of 40,000 DKK. The capital can be paid in cash or as non-cash contributions (assets), subject to valuation rules. In addition, you should expect formation costs for legal and accounting assistance, as well as ongoing costs for maintaining corporate documents and annual reporting.

Taxation of profits

In a sole proprietorship, business profits are taxed as your personal income. The profit after deductible expenses is included in your personal tax return and is subject to:

• Labour market contribution (AM-bidrag) of 8%
• Municipal and church tax (rates vary by municipality, typically around 24–27% combined)
• Bottom tax and, where applicable, top tax (topskat) of 15% on personal income above the top tax threshold

Depending on your total income and municipality, the marginal tax rate on additional business profit can approach around 52–56% including AM-bidrag.

An ApS pays corporate income tax (selskabsskat) on its taxable profit. The corporate tax rate is 22%. If you leave profits in the company, the total tax burden is limited to this 22% until you distribute dividends or pay salary. When you pay dividends to yourself as a private person, they are taxed as share income (aktieindkomst). Share income is taxed progressively with a lower rate up to a certain threshold and a higher rate above that threshold. Salary from the ApS is taxed as personal income in the same way as employment income and is deductible for the company.

This means an ApS can offer more flexibility in timing and splitting income between salary and dividends, which can be advantageous if your profits are higher and you do not need to withdraw all earnings immediately for private consumption.

Tax schemes and profit retention

Sole proprietors can use specific Danish tax schemes such as the business tax scheme (virksomhedsskatteordningen, VSO) or the capital returns scheme (kapitalafkastordningen) to achieve some of the same benefits as a company, for example deferring tax on retained profits or separating capital income from personal income. However, these schemes have detailed rules and documentation requirements.

In an ApS, profits are naturally retained in the company and taxed at the corporate rate until distributed. This can be beneficial if you plan to reinvest earnings in the business, build up reserves or invest in assets over several years.

Social security and salary

As a sole proprietor you are not considered an employee of your own business. You cannot pay yourself a salary with normal payroll tax treatment; instead, you withdraw owner’s drawings, and the profit is taxed via your personal tax return. You are responsible for arranging your own pension, insurance and any voluntary unemployment insurance (A-kasse) as a self-employed person.

In an ApS you can be employed by your own company and receive a salary. The company must run payroll, withhold A-tax, AM-bidrag and pay ATP contributions. This structure can make it easier to access certain employee benefits, pension schemes and unemployment insurance arrangements that are designed for employees.

Accounting, reporting and administration

Sole proprietorships have simpler formal requirements. You must keep proper bookkeeping records and submit an annual tax return, but there is no requirement for filing annual financial statements with the Danish Business Authority (Erhvervsstyrelsen) as long as you are not subject to special industry rules. Many small sole proprietors can manage with relatively simple accounting software and do not need an auditor.

An ApS is subject to the Danish Financial Statements Act (årsregnskabsloven). The company must:

• Prepare annual financial statements in a prescribed format
• File the annual report digitally with Erhvervsstyrelsen within the statutory deadline
• Maintain formal corporate records, including general meeting minutes and ownership registers

Smaller ApS companies can often opt out of statutory audit if they remain below certain size thresholds for revenue, balance sheet total and number of employees. Nevertheless, the administrative burden and expectations regarding documentation and governance are higher than for a sole proprietorship.

Image, credibility and growth potential

An ApS is often perceived as more professional and stable by banks, investors and larger customers. The requirement for share capital and formal reporting can signal seriousness and financial discipline. This can be important if you:

• Apply for bank financing or credit lines
• Negotiate with larger corporate clients or public institutions
• Plan to bring in co-owners or external investors

A sole proprietorship is usually sufficient for smaller, owner-driven businesses where the owner is closely involved in all operations and financing needs are limited. However, if you expect rapid growth, international expansion or the need for external capital, starting or later converting to an ApS can be advantageous.

Ownership structure and transferability

A sole proprietorship can only have one owner. You cannot issue shares or easily bring in partners as co-owners of the same legal entity. Cooperation is usually structured via contracts, profit-sharing agreements or by forming a new company together.

An ApS can have one or more shareholders. Ownership is represented by shares that can be transferred, sold or gifted, subject to any shareholder agreements. This makes it easier to:

• Bring in business partners as co-owners
• Reward key employees with ownership stakes
• Plan succession or sale of the business

Risk profile and when to choose which form

A sole proprietorship is typically best suited when:

• Your business risk is limited (for example, consulting, freelancing, small online services)
• Your turnover and profits are relatively modest
• You want the simplest and cheapest possible structure
• You are comfortable with personal liability for business obligations

An ApS is often more appropriate when:

• You operate in a sector with higher financial, contractual or product liability risk
• You expect significant profits and want flexibility in tax planning and profit retention
• You need to build credibility with banks, investors and larger customers
• You plan to have co-owners, investors or to sell the business in the future

Choosing between a sole proprietorship and an ApS in Denmark is ultimately a balance between simplicity and protection. A Danish accounting firm can help you calculate the expected tax impact, assess your risk exposure and, if needed, assist with setting up or converting to the structure that best supports your long‑term business goals.

Liability and risk management for sole proprietors (insurance, contracts, separation of assets)

As a sole proprietor (enkeltmandsvirksomhed) in Denmark, you and your business are legally the same person. This means you have unlimited personal liability for all business obligations. If the business cannot pay its debts, creditors can pursue your private assets, including your bank accounts, car and, in some situations, your home. Effective risk management is therefore essential from the moment you start your activity.

Unlimited liability in a Danish sole proprietorship

In an enkeltmandsvirksomhed there is no separate legal entity. You sign contracts, take loans and assume obligations in your own name and CPR number. Typical risks include unpaid supplier invoices, lease agreements, tax and VAT debts, compensation claims from customers and fines for regulatory breaches.

Unlike an ApS, there is no minimum share capital that limits your exposure. Even if your business assets are modest, you can still be held personally liable for the full amount of any claim. Danish authorities such as Skattestyrelsen can offset unpaid taxes and VAT against your personal tax refund and, in serious cases, initiate enforcement proceedings.

Separating business and personal finances in practice

Although you cannot create full legal separation without changing the legal form (for example to an ApS), you can and should create a clear financial separation between business and private life. This helps manage risk, simplifies bookkeeping and is important in case of tax audits or disputes.

Key measures include:

• Opening a dedicated business bank account and payment card and using them exclusively for business income and expenses
• Issuing all invoices with your business name, CVR number and clear payment terms
• Keeping written agreements for all significant business transactions (suppliers, customers, landlords, subcontractors)
• Avoiding the use of private accounts for business payments and vice versa, except for documented owner’s withdrawals and deposits
• Maintaining proper bookkeeping and storing documentation for at least 5 years, as required by Danish accounting rules

For married sole proprietors, it is also worth considering a ægtepagt (marital property agreement) with legal advice, to clarify how business-related risks may affect shared assets.

Key insurance types for Danish sole proprietors

Insurance is one of the most effective tools to limit the financial consequences of business risks. The exact needs depend on your industry, turnover, number of employees and whether you work from home, at a client’s site or from rented premises. Typical policies for a Danish sole proprietorship include:

Business liability insurance (erhvervsansvarsforsikring)

Business liability insurance covers claims if your business causes personal injury or property damage to third parties in the course of your work. For example, if you damage a client’s equipment on site or a customer is injured due to your negligence, the insurer can cover compensation and legal costs up to the agreed limit.

In many industries, clients will require proof of liability insurance before signing a contract. Limits are often set per claim and per year, for example DKK 2–10 million, depending on risk and sector.

Professional indemnity insurance (erhvervs- eller rådgiveransvar)

If you provide advice or professional services (IT consulting, accounting, design, engineering, marketing, legal or financial advisory), you should consider professional indemnity insurance. It covers financial losses suffered by clients due to professional errors, incorrect advice or omissions.

Some regulated professions in Denmark are required by law or by their professional body to hold such insurance. Even where it is not mandatory, it is often a contractual requirement and a key element of risk management for knowledge-based businesses.

Content, property and cyber insurance

Depending on your setup, you may also need:

• Business contents insurance for equipment, inventory, tools, computers and furniture against fire, theft, water damage and vandalism
• Property insurance if you own business premises, or to supplement the landlord’s insurance if you rent
• Cyber insurance if you process customer data, run an online shop or rely heavily on IT systems, to cover data breaches, cyberattacks and related liability

If you work from home, check whether your private home insurance covers business equipment and activities. In many cases, you will need an extension or a separate business policy.

Insurance for illness, accidents and loss of income

As a self-employed person in Denmark, you do not automatically have the same coverage as employees through an employer. To protect your personal finances, consider:

• Occupational injury insurance (arbejdsskadeforsikring) – mandatory if you have employees, and relevant for yourself if you work in a high-risk environment
• Accident insurance – to cover permanent injury or disability after an accident, whether work-related or private
• Health insurance – to access faster treatment and reduce downtime
• Income protection or sickness insurance – to secure a monthly benefit if you are unable to work due to illness or injury

It is also important to review your pension savings and any associated insurance (for example disability cover) to ensure they match your risk profile as a sole proprietor.

Contracts as a tool to manage risk

Well-drafted contracts are just as important as insurance. They help prevent disputes, clarify expectations and limit your liability where legally possible. For a Danish sole proprietorship, focus on:

• Clear scope of services – describe exactly what you deliver, what is excluded and what assumptions you rely on
• Prices and payment terms – specify hourly rates or fixed prices, invoicing frequency, due dates, interest on late payment and reminder fees in line with Danish law
• Liability limitations – where appropriate and legally valid, limit your liability to a certain amount (for example the contract value or a specific DKK cap) and exclude indirect losses
• Intellectual property rights – define who owns the rights to designs, software, texts or other deliverables
• Confidentiality and data protection – especially if you handle personal data under the GDPR or sensitive business information
• Termination and notice periods – clarify how and when each party can terminate the agreement and what happens with ongoing work

For larger or long-term contracts, it is advisable to have a lawyer review your standard terms and conditions. This is a one-time investment that can significantly reduce your legal risk.

Managing credit risk and customer payments

One of the most common risks for Danish sole proprietors is late or missing payments from customers. To reduce this risk:

• Check new customers’ creditworthiness, especially for large orders
• Use written offers and order confirmations before starting work
• Consider deposits or partial prepayments for larger projects
• Invoice promptly and follow up systematically on overdue invoices
• Use reminder procedures and, if necessary, collection agencies in accordance with Danish rules on debt collection and reminder fees

Efficient credit management protects your cash flow and reduces the risk that you cannot meet your own obligations, including VAT and tax payments.

When to consider changing to an ApS

For some sole proprietors, the most effective way to limit personal liability is to convert the business into a private limited company (ApS). An ApS is a separate legal entity with a minimum share capital of DKK 40,000, and as a general rule, only the company’s assets are at risk for business debts.

It may be relevant to consider an ApS if:

• Your turnover and profit are growing and you are building significant value in the business
• You operate in a sector with higher risk of claims or large contractual obligations
• You want to bring in partners or investors
• You plan to sell the business in the future

However, even with an ApS, banks and landlords may require personal guarantees, and you must comply with more formal accounting and reporting obligations. A Danish accounting firm can help you evaluate whether and when such a change makes sense from both a risk and tax perspective.

Effective liability and risk management in a Danish sole proprietorship is an ongoing process. By combining clear financial separation, appropriate insurance, solid contracts and disciplined credit control, you can significantly reduce the impact of potential problems on your personal finances and ensure a more stable foundation for your business growth.

Closing, suspending or transforming a Danish sole proprietorship (procedure and tax consequences)

At some point you may decide to pause, close or convert your Danish sole proprietorship (enkeltmandsvirksomhed). Each option has different legal and tax consequences, so it is important to plan the process carefully and report correctly to the Danish authorities.

Closing a Danish sole proprietorship

When you permanently stop your business activity, you must deregister the sole proprietorship and settle all outstanding obligations. The key steps are:

• Log in to Virk.dk with MitID and deregister the business from the CVR register. If you are VAT registered, you must deregister for moms at the same time.
• Submit your final VAT return to Skattestyrelsen. You must report and pay VAT up to and including the last day of business activity, according to your normal reporting frequency (monthly, quarterly or half‑yearly).
• File your final tax return as a self‑employed person via TastSelv Erhverv. You must complete the business tax form (udvidet selvangivelse / business schedule) for the last income year.
• Settle any outstanding A‑tax, AM‑bidrag and holiday pay if you have employees, and deregister as an employer in eIndkomst.
• Close or adjust your ATP, pension and insurance arrangements that are linked to the business.

From a tax perspective, closing the business means that all assets and liabilities are considered realised. This can trigger taxable gains or deductible losses.

Tax consequences when closing

When you close your sole proprietorship, you must calculate the tax effect of selling or taking over business assets. Typical areas to consider:

• Depreciable assets (machinery, equipment, IT, vehicles): if the sales price or private withdrawal value is higher than the remaining tax value, the difference is a taxable gain. If it is lower, you may have a deductible loss.
• Inventory: remaining stock that you sell or take for private use must be valued at market value and included in your taxable income.
• Goodwill and customer base: if you sell the business, the price for goodwill is taxable as business income. In some cases, the buyer can depreciate the goodwill over time.
• Business premises: if you own property used for the business, the sale or transfer to private use may trigger tax on real estate gains under the Danish property rules.
• Receivables and liabilities: outstanding invoices are taxable when earned, even if not yet paid. Unpaid supplier invoices can normally be deducted when the obligation is final.

If you have used the business tax scheme (virksomhedsskatteordningen, VSO), closing the business requires a final settlement of the scheme. The remaining balance in the business account and any previously retained profits are moved to personal income and taxed accordingly. It is important to calculate this correctly to avoid unexpected back taxes.

Suspending (temporarily pausing) a sole proprietorship

If you plan to resume your activity later, you can choose to suspend the business instead of closing it completely. In practice this means:

• You stop active operations (no new sales, contracts or employees), but you keep the CVR number.
• You can deregister for VAT if you do not expect any taxable turnover during the suspension period. If you keep your VAT registration, you must still submit returns (even with zero figures).
• You must continue to keep accounts and documentation and comply with the 5‑year retention requirement for bookkeeping material.
• Assets can remain in the business, but you must still handle any private use (for example of a car or home office) according to the tax rules.

Suspension is useful if you expect a break in activity (for example due to parental leave, studies or a longer stay abroad) but want to keep the structure and possibly the brand. From a tax perspective, there is no final realisation of assets as long as the business is only paused and not closed.

Transforming a sole proprietorship into an ApS

Many entrepreneurs eventually convert their sole proprietorship into a private limited company (ApS) to limit personal liability and optimise taxation. In Denmark you can transform the business either as a taxable transfer or as a tax‑free business conversion (skattefri virksomhedsomdannelse).

Taxable transfer

In a taxable transfer you sell the assets and liabilities of the sole proprietorship to the new ApS at market value. The consequences are:

• Any gains on assets (for example goodwill, equipment or property) are taxed in your personal income in the year of transfer.
• The ApS gets a tax acquisition value equal to the purchase price and can depreciate assets according to the corporate tax rules.
• You can receive payment from the ApS in the form of cash, a shareholder loan (within the strict Danish rules on shareholder loans) or shares.

This model can be relevant if the business has limited hidden gains or if you want to realise value immediately.

Tax‑free business conversion (skattefri virksomhedsomdannelse)

A tax‑free conversion allows you to move the entire business into an ApS without immediate taxation of hidden gains, provided that you meet a number of statutory conditions. Key requirements include:

• The conversion must take place at the beginning of an income year and cover the entire business (not just selected assets).
• You must transfer all assets and liabilities related to the business to the ApS at their tax values, not market values.
• You must receive shares in the ApS as consideration. You may not receive cash or other assets as part of the tax‑free transfer.
• You must prepare an opening balance sheet for the ApS and a conversion statement that documents the tax values.
• If you use the VSO scheme, the scheme must be closed correctly and the balances transferred to the company according to the special rules for tax‑free conversion.

The effect of a tax‑free conversion is that taxation of gains on assets such as goodwill, inventory and equipment is postponed until the ApS later sells the assets or is liquidated. You continue the depreciation and tax positions in the company.

Practical steps when transforming to an ApS

Regardless of whether you choose a taxable or tax‑free conversion, you must:

• Register the new ApS with the Danish Business Authority via Virk.dk and pay in the required minimum share capital (currently 40,000 DKK).
• Prepare transfer documentation (transfer agreement, opening balance sheet, valuation of assets and liabilities).
• Update contracts with customers, suppliers, landlords and employees so that the ApS becomes the new contracting party.
• Adjust your VAT registration so that future sales are reported under the CVR number of the ApS.
• Close or scale down the sole proprietorship once the transfer is completed and all activities have been moved.

When to involve an accountant

Closing, suspending or transforming a Danish sole proprietorship involves several tax and legal choices that can have long‑term financial consequences. Errors in the final VAT return, the last business tax form or in a tax‑free conversion can lead to unexpected tax bills and interest. A Danish accounting firm can help you:

• Plan the optimal timing of closure or conversion in relation to your income, deductions and VSO balances
• Calculate gains and losses on assets and handle the final settlement with Skattestyrelsen
• Prepare the necessary documentation, opening balance sheets and transfer agreements for an ApS
• Ensure correct reporting and deregistration in CVR, VAT and eIndkomst

With professional support you can complete the process smoothly, minimise tax risks and ensure that your transition to the next phase – whether that is a pause, a complete exit or a new company structure – is compliant and financially sound.

Common mistakes when starting a sole proprietorship in Denmark and how to avoid them

Many foreign entrepreneurs and new freelancers underestimate how different Danish rules can be from those in other countries. Below are the most common mistakes when starting a sole proprietorship (enkeltmandsvirksomhed) in Denmark – and how to avoid them in practice.

1. Starting business activity before proper registration

A frequent mistake is issuing invoices or signing contracts before registering the business with the Danish Business Authority (Erhvervsstyrelsen) and the Danish Tax Agency (Skattestyrelsen).

If you start trading without a CVR number and tax registration, you risk incorrect VAT handling, problems with customers’ bookkeeping and potential fines.

To avoid this, always:

• Register your sole proprietorship at virk.dk before your first invoice
• Register for VAT (moms) if you expect turnover above 50,000 DKK in any 12‑month period
• Register for A‑tax and AM‑bidrag if you will pay yourself salary as an employer (e.g. if you also have employees)

2. Confusing personal and business finances

In a sole proprietorship you and the business are the same legal person, but mixing finances is still a major practical and tax mistake.

Typical problems include using one bank account for everything, paying private expenses from the business account without documentation, and not distinguishing between private use and business use of assets.

To avoid this:

• Open a separate business bank account and use it only for business income and expenses
• Always keep invoices and receipts for business costs
• Document private use of business assets (e.g. car, phone, internet) and make correct private use adjustments

3. Ignoring VAT (moms) rules and thresholds

Many small sole proprietors assume they are “too small” for VAT or register too late. In Denmark you must register for VAT when your taxable turnover exceeds 50,000 DKK within any 12‑month period.

Common mistakes include:

• Not monitoring turnover and missing the 50,000 DKK threshold
• Charging VAT without being registered
• Using the wrong VAT rate (standard 25% vs. VAT‑exempt activities)
• Missing VAT reporting and payment deadlines

As a sole proprietor you usually report VAT either quarterly or half‑yearly, depending on your turnover. Always check your assigned VAT period in TastSelv Erhverv and put the deadlines in your calendar.

4. Choosing the wrong tax scheme (B‑income vs. VSO vs. capital returns scheme)

Another frequent mistake is choosing a tax setup that does not fit the size and type of your business. In Denmark, sole proprietors can typically choose between:

• Taxation as personal B‑income (no special scheme)
• The business tax scheme – virksomhedsskatteordningen (VSO)
• The capital returns scheme – kapitalafkastordningen

Problems arise when entrepreneurs:

• Use VSO without understanding the bookkeeping and equity requirements
• Miss the deadline to opt into a scheme for the tax year
• Underestimate the impact of the top tax (topskat) threshold on their total tax burden

As a rule of thumb, VSO is most relevant if you have a higher profit and want to defer tax by retaining earnings in the business at the business tax rate (currently 22%). For many small freelancers with modest profit, simple B‑income taxation can be more practical. Always run concrete calculations before deciding.

5. Underestimating preliminary tax (B‑tax) and AM‑bidrag

Many new sole proprietors forget that they must pay tax and labour market contribution (AM‑bidrag) on an ongoing basis, not only when they file the annual tax return.

Typical mistakes:

• Not updating the preliminary income assessment (forskudsopgørelse) when starting the business
• Setting expected profit too low, leading to a large tax bill later with interest
• Ignoring B‑tax instalments and AM‑bidrag deadlines

To avoid cash flow shocks:

• Update your forskudsopgørelse as soon as you know your expected annual profit
• Review and adjust it during the year if your income changes significantly
• Set aside a fixed percentage of your profit (often 40–50% depending on your total income and municipality) for tax and AM‑bidrag

6. Poor bookkeeping and missing documentation

Even though many sole proprietors are not required to submit annual financial statements to Erhvervsstyrelsen, they must still keep proper accounts for tax and VAT.

Common mistakes include:

• Keeping only bank statements without invoices and receipts
• Not numbering and archiving invoices systematically
• Using spreadsheets without backup or clear structure
• Not keeping records for the required retention period (normally 5 years)

To avoid problems in a tax or VAT audit, use proper accounting software, keep digital copies of all documents and reconcile your bank account regularly.

7. Misunderstanding deductible expenses

Many new sole proprietors either deduct too much (risking corrections and penalties) or too little (paying unnecessary tax).

Typical issues:

• Deducting private expenses as business costs
• Not applying correct rules for home office, car, phone and internet
• Ignoring depreciation rules for assets above certain values
• Forgetting that some costs are only partially deductible (e.g. representation)

In Denmark, only expenses that are directly related to earning business income are deductible. For mixed use assets, you must allocate between private and business use based on a reasonable and documented method.

8. Overlooking social security, pension and insurance

Self‑employed in Denmark are not automatically covered in the same way as employees. A frequent mistake is assuming that “the system” will take care of everything.

Common oversights:

• No voluntary unemployment insurance (A‑kasse) or income protection
• No pension contributions, leading to low retirement savings
• No business liability insurance or professional indemnity insurance
• No workers’ compensation insurance if you use employees or certain helpers

Review your social security situation, consider joining an A‑kasse, set up regular pension contributions and discuss relevant insurance policies with an adviser.

9. Ignoring contractual and liability risks

In a sole proprietorship you have unlimited personal liability. Many entrepreneurs sign contracts or take on obligations without understanding the risk.

Typical mistakes:

• Signing long‑term leases or supplier contracts without legal review
• Not using written contracts with customers and freelancers
• Accepting liability clauses that are disproportionate to the fee

To reduce risk, always:

• Use clear written agreements for projects and ongoing services
• Limit your contractual liability where possible
• Consider whether an ApS would be more appropriate if your risk level is high

10. Missing deadlines for annual tax and VAT reporting

Another common mistake is not respecting Danish reporting deadlines. Late filing can lead to estimated assessments, interest and penalties.

Key points to remember:

• Annual personal tax return (including business income) must be filed electronically via TastSelv
• VAT returns must be submitted and paid by the specific deadlines for your reporting period
• Employer declarations (if you have employees) must be reported monthly

Use calendar reminders or accounting software with automatic alerts, and consider delegating reporting to an accountant if you are unsure.

11. Not planning for growth, change or exit

Many sole proprietors start small and then grow without adjusting their structure. This can lead to unnecessary tax, administrative burden or risk.

Typical mistakes:

• Keeping the sole proprietorship even when profit and risk would justify an ApS
• Not planning the tax consequences of closing or transforming the business
• Ignoring the impact of investments and goodwill on future taxation

If your turnover and profit increase significantly, or if you take on larger contracts and employees, it may be time to evaluate whether an ApS or another structure is more suitable.

How to avoid these mistakes in practice

The safest way to avoid costly errors is to set up your sole proprietorship correctly from the beginning:

• Clarify your business model, expected turnover and profit before registration
• Choose the right tax scheme based on concrete calculations
• Implement simple but robust bookkeeping routines and software
• Monitor VAT thresholds and tax instalments throughout the year
• Review your setup annually with a Danish accountant or tax adviser

Investing a bit of time and professional advice at the start will usually save you both money and stress later – and allow you to focus on growing your Danish sole proprietorship.

How a Danish accounting firm can support your sole proprietorship (from setup to ongoing compliance)

A Danish accounting firm can support your sole proprietorship at every stage – from the first registration with the Danish authorities to ongoing bookkeeping, tax returns and strategic planning. Professional support is especially valuable in Denmark, where the rules for VAT, tax schemes and reporting deadlines are detailed and change regularly.

Support when setting up your sole proprietorship

At the start, an accounting firm can help you choose the right structure and register your business correctly:

• Assess whether a sole proprietorship is the best choice compared to an ApS, based on your expected turnover, risk level and personal situation
• Register your business with the Danish Business Authority (Erhvervsstyrelsen) and obtain a CVR number via virk.dk
• Register for VAT (moms) if your expected turnover exceeds DKK 50,000 over 12 months, and choose the correct VAT reporting frequency (monthly, quarterly or half-yearly)
• Register as self-employed with the Danish Tax Agency (Skattestyrelsen) and submit the preliminary income assessment (forskudsopgørelse)
• Set up access to e-Boks and MitID for digital communication with public authorities

This ensures that your sole proprietorship is compliant from day one and avoids delays or penalties caused by incorrect or missing registrations.

Choosing and implementing the right tax scheme

Danish tax rules for sole proprietors offer several schemes, and the choice can significantly affect your total tax burden. An accounting firm can:

• Analyse whether you should be taxed as personal B-income, use the business tax scheme (virksomhedsskatteordningen, VSO) or the capital returns scheme (kapitalafkastordningen)
• Calculate the effect of VSO, including the possibility to retain profit in the business at the business tax rate (currently 22%) and defer personal tax
• Determine the optimal split between salary-like withdrawals and retained profit
• Prepare and submit the necessary forms and appendices in TastSelv Erhverv

Correct use of VSO or the capital returns scheme can reduce your marginal tax rate and improve liquidity, but requires precise bookkeeping and correct year-end adjustments.

Ongoing bookkeeping and VAT compliance

Accurate and timely bookkeeping is crucial in Denmark, where documentation requirements are strict and VAT control is common. An accounting firm can:

• Set up a bookkeeping system adapted to your business (for example Dinero, e-conomic, Billy or other approved software)
• Establish a chart of accounts that separates private and business transactions and distinguishes between deductible and non-deductible costs
• Handle daily bookkeeping, bank reconciliations and invoice registration
• Calculate and submit VAT returns on time:
  • Monthly reporting for larger businesses
  • Quarterly or half-yearly reporting for smaller businesses, depending on turnover
• Ensure correct treatment of Danish and cross-border transactions (EU B2B, reverse charge, OSS/IOSS where relevant)

With professional support, you reduce the risk of VAT errors, which can otherwise lead to back payments, interest and surcharges.

Payroll, social contributions and employer obligations

If your sole proprietorship hires employees, your obligations increase significantly. An accounting firm can:

• Register you as an employer and set up the business in the eIncome (eIndkomst) system
• Run payroll, calculate A-tax, AM-contribution (8%) and holiday pay according to the Danish Holiday Act
• Report salary data to Skattestyrelsen and ATP, and handle mandatory labour market contributions
• Advise on collective agreements, minimum requirements for employment contracts and staff benefits
• Coordinate with insurance brokers regarding workers’ compensation insurance and other mandatory employer insurance

This allows you to focus on your core business while ensuring that all employer-related obligations are handled correctly and on time.

Year-end accounts and tax returns

At the end of the income year, a Danish accounting firm plays a key role in preparing your financial statements and tax returns. Typical services include:

• Preparation of the annual accounts for your sole proprietorship in accordance with Danish rules
• Reconciliation of all balance sheet items and review of documentation for income and expenses
• Calculation of taxable profit, including depreciation of fixed assets and correct treatment of interest and private withdrawals
• Completion of the business tax return (udvidet selvangivelse) and relevant appendices in TastSelv
• Optimisation of deductions, for example:
  • Home office expenses and car expenses (actual costs vs. mileage allowance)
  • Representation, travel and course costs
  • Pension contributions and interest deductions

Professional preparation of your accounts and tax return reduces the risk of errors, tax audits and unexpected additional tax.

Advisory on risk management and insurance

Because a sole proprietor is personally liable for business debts, risk management is particularly important. An accounting firm can:

• Help you assess your risk profile and recommend appropriate insurance (professional liability, product liability, business interruption, cyber insurance)
• Advise on separation of private and business finances, including separate bank accounts and clear documentation of private withdrawals
• Evaluate whether and when it is advantageous to convert your sole proprietorship into an ApS to limit personal liability

This reduces your personal financial risk and strengthens the long-term stability of your business.

Strategic and financial planning

Beyond compliance, a Danish accounting firm can act as a long-term sparring partner for your sole proprietorship. Typical advisory areas include:

• Budgeting and liquidity planning, including cash flow forecasts and break-even analysis
• Pricing strategies and profitability analysis of products or services
• Investment decisions and financing options, including bank negotiations and preparation of financial documentation
• Tax planning across several years, for example timing of investments, withdrawals and pension contributions to smooth your marginal tax rate
• Preparation for growth, hiring and possible later conversion to an ApS

With regular financial reporting and proactive advice, you gain better control over your business and can make decisions based on up-to-date figures rather than assumptions.

Digital tools and automation

Modern Danish accounting firms typically work digitally and can help you automate many administrative tasks:

• Implementation of digital invoicing (including e-invoices to public authorities via EAN)
• Bank integrations that automatically import transactions into your accounting system
• Use of apps for receipt scanning and automatic posting
• Setting up dashboards with key performance indicators such as turnover, margin and liquidity

This reduces manual work, minimises errors and gives you real-time insight into your business finances.

Ongoing support and communication with authorities

Finally, an accounting firm can act as your representative towards Danish authorities and other stakeholders:

• Handle correspondence with Skattestyrelsen, Erhvervsstyrelsen and other public bodies via e-Boks
• Assist during tax audits or VAT inspections, including preparation of documentation and explanations
• Update you on relevant changes in Danish tax and VAT legislation that affect sole proprietors

With a professional partner, you avoid many administrative pitfalls and can concentrate on running and growing your sole proprietorship in Denmark.

Important aspects of running a sole proprietorship in Denmark

In addition to the basic steps involved in registering a sole proprietorship in Denmark, it is worth noting a few additional issues that can significantly affect the operation of your business.

One such element is insurance. Consider taking out adequate insurance to protect your business from potential risks. Depending on the type of business, this could include liability insurance, insurance for your business assets, or even insurance against accidents or damages resulting from your professional activities. Well-chosen insurance can protect you from unforeseen costs and provide peace of mind in the day-to-day running of your business.

Another important issue is licenses and permits. Make sure you have all the necessary licenses and permits required to legally operate your business. In Denmark, certain types of business may require special licenses, such as in the construction, medical, catering, or transportation industries. Failure to have the proper licenses can lead to financial penalties and even suspension of your business.

Additionally, certain businesses may be required to submit Intrastat declarations to report their trade in goods with other EU member states. These declarations provide crucial data on the volume and value of cross-border transactions and help monitor economic activity within the EU. Regularly reviewing your reporting obligations ensures that your business adheres to all relevant regulations.

Registering a sole proprietorship in Denmark is usually a simple and quick process that can be completed online. However, the key to success is to carefully follow all steps and deadlines, thus avoiding legal and administrative problems in the future. Careful preparation of documents, filings and attention to regulatory compliance will contribute to the successful operation of your business and minimize risks.
