Pre-completed tax return

The final result of your tax assessment is stated in your tax decision

If you made no additions or corrections

If you or your spouse did not make any corrections, the tax decision you received in spring as well as the tax certificate and any bank transfer forms for back taxes remain valid. In this case, you will receive no additional decision letter.

If you added or corrected something

You will receive a new tax decision if

you have made corrections to the pre-completed tax return
your spouse has made corrections to his or her tax return
the Tax Administration has received corrections from other sources.

In that case the payment date of your tax refund or the due dates of your back taxes will probably be postponed. We will send the new tax decisions to taxpayers before the end of October.

Check the details in the tax decision

When you receive your tax decision, check that the information is correct.

If you find an obvious error in the tax decision (such as a mistake in a mathematical calculation, etc.), call our service number stated on the decision. That way, we can correct the error before your tax assessment ends.

If you notice that there are income or deduction details missing in your tax decision, submit them in MyTax or on paper before the end date of your tax assessment. You can find the end date on the tax decision that is also in MyTax. How to find the tax decision in MyTax.

If you check your information but do not notice an error until after the end date, you can make a formal claim for adjustment.

Will you get a refund?

Most individual taxpayers will receive their tax refund on 3 August 2023 or on 4 September 2023. The exact date may vary. You can see your personal refund date in MyTax and on your tax decision. Remember to also check that your bank account number is correct.

If you corrected or added something to your tax return, the date of your refund will probably be pushed forward.

Will you have to pay back taxes?

Most of those individuals who have back taxes must pay the first instalment by 1 August 2023 and the second instalment by 2 October 2023. The dates may vary. Remember to check your personal due dates in MyTax or on your tax decision. If you added or corrected something to your tax return, the dates when you must pay back tax will probably be pushed forward.
