Corporation tax should be declared via our online option: E-tax for companies (TastSelv Selskabsskat). This applies to all companies, foundations and associations.

The reporting deadline for companies has been extended to Thursday 7 July 2022

Last week, NemID caused problems to such an extent that companies were unable to do their reporting in E-tax Business DIAS, putting great pressure on DIAS. As a result, we have extended the reporting deadline for companies by a week to allow time for reporting. Companies with an accounting year that expired on 31 December 2021 have had their reporting deadline extended from Thursday 30 June 2022 to Thursday 7 July 2022.
The extension only applies to companies. The deadline for individuals and sole proprietorships remains 1 July 2022.
