What is a tax return?

You'll receive a pre-completed tax return from the Norwegian Tax Administration in April if you work in Norway or on the Norwegian continental shelf. The tax return is a summary of income, deductions, wealth and debts for one calendar year. The summary is based on the information that was registered for you as of 31 December in the calendar year concerned.

The information in the tax return forms the basis for your annual tax assessment. To make sure you don't pay too much tax, you must check that the information in your tax return is correct.

The tax return contains a preliminary calculation of whether you've paid too much tax (overpaid tax) or too little tax (underpaid tax). Note that this calculation isn't final and that the Norwegian Tax Administration may make changes to this calculation until we have processed your tax return and you receive your tax assessment notice. That's why it's important that you let us know if your tax return contains any errors.

You're responsible for ensuring that the tax return is correct. You must check the information and correct any errors or missing information.

If all the information is correct and you don't make any changes, you don't have to do anything. 

If you haven't received your tax return, contact the Norwegian Tax Administration and ask to be sent a new tax return. This also applies if you have lost your tax return.

The Norwegian Tax Administration communicates electronically with the public. There are many advantages to becoming an online user.
