To receive payments from the Tax Administration, you must log in and register an account number. If you wish to change the account number, log in and change to a different account number.
If you do not have a Norwegian BankID and you’re not an online user, you can use the form kontoopplysninger (“account information”) available on the Norwegian tax admistration web page to change your account number.
You send the filled out form to the following address:
