How to do your tax return
More about tax return
The tax return first, then the tax assessment notice
When you have filed the tax return, we calculate the tax payable for the company, foundation or association and generate a tax assessment notice (årsopgørelse).
The tax assessment notice is always released each year in October via Digital Post. The tax assessment notice for income year 2024 was released via Digital Post in October 2025.
Please note that it's only the management company of joint taxation companies that receives the tax assessment notice.
You can also find the tax assessment notice in E-tax for businesses (TastSelv Erhverv) > Contact > Message Archive.
Outstanding tax and overpaid tax
The deadline of paying possible outstanding tax is 20 November. If the deadline is a weekend or a holiday, the deadline will be the coming weekday.
Refund of possible overpaid tax will be made to the company's Tax Account on 20 November. If the overpaid tax is not used for paying other charges in the Tax Account, it will be transferred to the NemKonto of the company subsequently.
