You will find the basis for determining the amount that you must pay in the a-melding which you submitted in the two previous months.
Who do you make the payment to?
Payments must generally be made to the Norwegian Tax Administration. When you submit an a-melding, you will receive feedback giving the account number, KID and to whom you should make the payment. You will find this feedback in 'My message box' in Altinn or in your payroll system. You must add the two months together before making the payment.
