The deadline for correcting your tax assessment notice has been extended to 1 September 2020 (due to the corona situation).
See the extended deadlines in the list below. Some of the deadlines are in August and December.
It is an advantage to make corrections as soon as possible
Even though the deadlines have been extended, it would be an advantage for you to make the corrections as soon as possible.
If you are getting a tax refund, you will get it sooner than if you wait to correct your tax assessment notice.
If you have outstanding tax, you can save money if you pay it before 1 July 2020. The deadline for voluntary payment of outstanding tax has not been extended.
If you pay your outstanding tax before 1 July 2020, daily interest of 2% will be added up to and including the payment date. If you choose to pay after 1 July 2020, you will pay a 4% fixed additional interest charge.
Any outstanding tax you have up to DKK 21,320, including the additional interest charge, will be included in your tax for 2021.
Any outstanding tax you have over DKK 21,320, including the additional interest charge, will be charged in three instalments in August, September and October. We will notify you via digital post when it is time to pay the first instalment. Please note that the extended declaration deadline of 1 September may mean that your instalments may be charged at a later point in time.
