Tax assessment notice
Once your tax return has been processed, you'll receive a tax assessment notice.
This year, nearly all earners and pensioners got their tax assessment during the period 2 April - 22 June. After this, we’ll continue sending out tax assessment notices from 12 August to 30 November.
The tax assessment notice will state whether you've paid too much or too little tax. If you've paid too much tax, you'll be refunded the excess amount. If you've paid too little tax (underpaid tax), you must pay the amount that you owe. Tax assessment notices will be made available during the period June to November in the year after you performed the work in Norway.
When you receive your tax assessment notice, you must check that the information given in it is correct.
Even if you submit an amended tax return or appeal against your tax assessment, you must still pay any underpaid tax by the deadline.
Changes to your tax basis
If you believe your tax assessment contains errors, such as the income, wealth, deductions or tax or duty calculations, you can correct the errors yourself. You can do this by re-submitting your tax return with the necessary changes. After the deadline for submitting the tax return has passed, you have three years to report any changes. You can re-submit your tax return several times.
As an online user, you can change your tax return online.
If you aren't an online user, you can send your amended tax return by post. You'll find the address to send it to on your tax assessment notice.
Appealing against tax deduction errors or omissions
If you discover withholding tax errors or omissions on your tax assessment notice, you must submit an appeal to the tax collector in your municipality. You'll find the tax collector’s address on your tax assessment notice. The deadline for receipt of appeals is three weeks after you receive your tax assessment notice.
In January, your employer will give you a summary showing the income, deductions and withholding tax that have been reported to us for the past year (calendar year). If you're an online user, you'll find this information in the form entitled “My income and employments” in Altinn. You can use this form to check your tax assessment notice.
If you've paid too much tax, the refund will be repaid within three weeks after the date stated in the top right-hand corner of your tax assessment notice. The refund will be transferred to the account we have registered for you.
If we don't have your account number, we won't be able to pay you your refund.
You can change the account number yourself if needed. To ensure you get your tax refund paid into the right account, you must change or register a new account as soon as possible.
You can also contact the tax collector in your municipality to register or change your account number.
