Do you have an identification number in the National Population Register and have been notified by BankID that you must re-identify yourself?

Then you must check that the National Population Register has registered the correct number from your ID document.

If you have a D number, you must also have the status "checked" registered in the National Population Register. 

How to re-identify yourself to update your electronic ID

If you've received the tax return for businesses, you must submit it. Even if you've terminated your business or have had no revenue, you must submit the tax return.

Submit the tax return for businesses

The deadline was 31 May. If you have not done so, submit the tax return as soon as possible to avoid an enforcement fine.

Once you have submitted your tax return, we need to process it and prepare a tax assessment. Most people receive the tax assessment notice between April and June, while others have to wait until autumn.

Unfortunately, we cannot give you a specific date for when you’ll receive your tax assessment notice. You’ll be notified.

Log in and check status on your tax assessment notice

If you have underpaid tax, you'll receive an invoice with payment information well before the due date. 

You don't have to wait for the invoice to pay. You can pay what you can right away and then pay little by little until the deadline. That way, you can create your own repayment plan. 

Pay underpaid tax

If you have underpaid tax, it is usually because not enough tax has been deducted during the year. Avoid underpaying your tax next year by checking the numbers in your tax deduction card for 2026. 

Check your tax deduction card

If you earn NOK 100,000 or less during the year, you can get an exemption card. If you have more than one employer, you must remember to split the tax-free amount. 

Order an exemption card

If you think you'll earn NOK 100,000 or more during the year, it's important that you order a tax deduction card instead.
