When and how do you pay?
As a self-employed worker, you must pay tax in advance — usually in 10 monthly instalments (January to May and July to November). If you pay too much, the excess will be refunded to you at the end of the period.
How to appeal/complain
If you disagree with your tax assessment, you can complain to the local tax authorities.
For details of exactly where and how, see your tax assessment letter.
As a next step, you can complain to the Landsskatteret (tax tribunal). The matter may subsequently be pursued in the Landsret (court) or Højesteret (High Court).
