Too much tax has been deducted from my pension/disability benefits. How will I get the money refunded?

In principle, excess tax deducted will be refunded in connection with the tax settlement next year.

When issuing a tax deduction card with a deduction rate of less than 15 percent, The Norwegian Tax Administration will take account of the amount of tax that has been deducted so far in determining the tax rate for the remaining part of the year.

If your whole pension/disability benefits is tax exempt because you are not liable to tax on your pension in Norway, you can apply for a refund of the tax that has already been deducted.
