You pay tax on your business by entering your expected profit or loss in your preliminary income assessment (forskudsopgørelsen). If your profit or loss changes, you can adjust it accordingly in your preliminary income assessment.
What is a tax return and who uses it?
When you have a personally owned business, we extend your tax assessment notice with a separate section for businesses where you have to report the profit or loss of your business. This is called a tax return.
You should also use the tax return if you:
- have non-Danish income or property
- have rented out a home that you do not live in personally
- are an artist and covered by the income equalisation scheme for artists
- operate with an irregular financial year
- own shares in investment project partnerships (ordinary or limited) (anparter) that are not subject to the rules governing such shares.
If you run your business in corporate form (partnership or limited company)
If you run your business in corporate form, you have to declare the profit or loss in E-tax for businesses (TastSelv Erhverv). Generally, companies and personally owned businesses are covered by different rules.
One of the differences is, that a company is taxed separately on its profit/loss and you will be considered an employee.

The reporting deadline is 1 July
You have to report your business result (profit or loss) for the past year and you can do that from mid-March when your tax assessment notice is accessible and until the deadline of 1 July.
Under certain circumstances, you can apply for an extension of your payment deadline. You can do so from mid-March until the deadline of 1 July.
If you miss the deadline, you will be charged a penalty for late filing of DKK 400 per day.
You can apply to be fully or partially exempt from this penalty if special circumstances are the reason you have not filed your tax return. If so, you need to inform us of such special circumstances and submit relevant information for us to consider.

The business tax scheme enables you to:
- have your business interest expenses taxed as personal income and not as capital income. By doing so you pay less labour market contributions (am-bidrag) and possibly less top-bracket tax than according to the general tax rules.
- save up in your business against paying tax on an ongoing basis. This means you can save up in good years and withdraw saved up profits in bad years.
If you save up in your business, you will be taxed at a rate of 22% on the part of the profit that you save up. When you withdraw an amount from the savings, you are taxed as for personal income, and the tax you have already paid will be deducted.
If you opt for the business tax scheme, you will have to separate your personal finances from your business finances. You can choose to be taxed under the business tax scheme in your preliminary income assessment by ticking field 184, but the actual choice is not made until when you complete your tax return (by ticking box 147).
The return on capital tax scheme may be a good alternative to the business tax scheme as this scheme is easier to manage.
A return on capital tax is calculated, which is taxed as income from capital instead of personal income. By doing so you pay less labour market contributions and possibly less top-bracket tax than according to the general tax rules.
The return on capital cannot be more than the largest of the following two amounts:
- Profit from business or
- The total negative income from capital (excluding the calculated return on capital)
You can choose to be taxed under the return on capital tax scheme in your preliminary income assessment by ticking field 184. However, you do not make your final decision about the scheme until you complete your tax return which is available in early March. You should complete box 141 under ‘Virksomhedsoplysninger’ (Business information).
