On December 16, the tax card for 2025 became available for Norwegians.
In order to calculate the correct tax for the upcoming year, it is important to check and make any necessary adjustments, says consumer economist Magne Gundersen at Sparebank 1.
– It is wise to check and change if there are errors. You should do this right away so that your payslip is correct from January, he says.
Do you need to change the tax card?
Gundersen recommends everyone to check their own tax card, but believes it is especially important for those who have had changes in their lives over the past year.
– That means if you have the same spouse, the same children, and have not moved since you last filled out your tax card, most of it should be correct.

Your income for 2025 on the tax card is calculated based on your October salary multiplied by 12. If October was an irregular salary month for you, the Tax Administration will use your income from October 2023.
Gundersen recommends entering the amount you believe is correct and not trying to “trick the system.”
– Many try to manipulate by entering lower salary amounts to pay less tax at the beginning of the year. This is foolish because you risk getting a tax bill if you do not later change to the actual amount. Just change what you believe is correct, he says.
What about deductions and interest?
The tax card includes several amounts that affect how much you will be taxed over a year.
– What most people change are interest rates on deposits and loans. But if you have not paid down more on your loan or have switched homes and taken on more debt, the figures from the Tax Administration should generally be accurate, assures Gundersen.

If you are unsure about your interest expenses, many can find this in the repayment plan in their online banking.
– When it comes to deductions, such as union dues deductions, the amounts will be based on what you have paid before. Be sure before you make any changes; those figures are there for a reason.
There is no limit to how many times you can change your tax card during the year. Gundersen recommends changing the tax card continuously if there is any change in your income situation.
– You can change it as many times as you want, but do it right away. That way, it gets updated and the change is spread throughout the year. Don’t wait until next December to make changes.

What is the tax card for?
Gundersen emphasizes that the tax card that came out on December 16 should be checked and submitted by December 31 to ensure that the salary in January is correct.
– This tax card that is being checked now is for the income year 2025, and if you have paid too much tax, you will get money back in the spring of 2026. It is too late to change anything regarding your salary for this year.
– Is it wise to change the tax card if you are unsure about what is correct?
– It is always wise to check because mistakes can happen, but the system has become incredibly good, so there is no point in changing because you think you are being smart, he says, adding:
– Additionally, the Tax Administration’s own website has a good guide if you are unsure about the numbers.
