If we have previously made a correction for a period, the business or the accountant can no longer make a correction for this particular period.

Please note that corrections previously made via forms or letters to us will not appear from your receipts in E-tax for businesses. The figures in the column ‘Tidligere indberetninger' (Previous VAT returns) have been summed up excluding any previous manual corrections. It is merely a question of how the figures are shown in E-tax for businesses.

We have registered your previous corrections made via forms and as a result, they do not need to be re-entered. However, if you have previously corrected a VAT return by means of form 31.009 and you now have additional corrections to the same VAT return, it is important that you enter the new difference in the column ‘Ændring' (Correction).

The column ‘Resultat' (Result) is likewise summed up excluding corrections previously made via forms.

We can only make such an increase on its own initiative if the under-declaration of VAT is due to gross negligence on the part of the business or business representative.

If you do not want us to reopen and change your VAT return, you can use the contact form to inform us of the error and why it has been made.

If you inform us of an error and we find that it is a question of gross negligence, we will increase your business' VAT declaration.

After three years from the time the VAT return was due, it can only be changed under certain conditions.

Conditions for changing VAT and taxes after the expiry of the three-year deadline

VAT and taxes can only be changed after the three-year deadline if:

• the declaration has been made according to our practice which has subsequently been overruled
• the change is a direct consequence of another change of the business' VAT/tax. If, for example, the business has a VAT deduction registered in a wrong period and we increase the VAT as a result, the business can claim the deduction in the right period even if the deadline has expired
• it is a question of certain conditions (see below)

Certain circumstances allowing for changes after the deadline

It must be external circumstances that cannot be blamed on the business or business consultant which have caused an incorrect declaration. Matters such as the business or the business consultant forgetting a deduction, misunderstanding rules or making wrong entries do not grant permission to deviate from the three-year deadline.

Permission to reopen a VAT return

If you want to apply for permission to have your VAT return reopened and corrected after the three-year deadline, please contact us by e-mail.

In your email, you will have to tell us which duty to be corrected and the correct amount.
