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 5 August 2024 or on 3 September 2024. 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 2024 and the second instalment by 1 October 2024. 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.

You can see the details for your back taxes in MyTax and on your tax decision. If you have received a preliminary tax calculation with your tax return, do not pay your back taxes until you have received your final tax decision.

If you own real estate, please note that the due dates for real estate tax are quite close to the due dates for back taxes (for most payers of real estate tax, the due dates are 6 August 2024 and 7 October 2024).

you have made corrections to your tax return

If you receive a new tax decision even if you have not made any corrections yourself, you should compare the new decision with the one from spring.

You cannot add enclosures or free-text pages with additional taxpayer-provided information for the tax return, unless you are filling in one of the specific MyTax pages where this is provided for.

After you have logged in to MyTax to make corrections to your pre-completed tax return, you can see that the sections and pages of MyTax contain questions that you must answer. Your answers are the main method of giving the information that the Tax Administration needs. It is enough if you just fill in each space with the amounts, facts, and details as appropriate.

For example, to claim a tax-deductible expense, you simply fill in the amount and the information that MyTax has asked you to give. No enclosures, receipts or documentation are necessary. However, you should keep the receipts and documentation in a safe place for possible future use. In the same way, the MyTax view of your tax return contains no extra spaces for free-text additions. The Tax Administration will communicate with you if any information is needed that you have not already given.

Some of MyTax’ sections contain an “Upload an attachment file” feature – one of them is the section for sales of securities such as corporate stocks. In this case, the words Enclosures and Add a file appear.

Please note that the MyTax view does not contain numbered enclosure forms (such as Form 7H Rental income – Apartments in a housing company, or other numbered forms).

Instead of having to fill in many numbered forms for different kinds of income, you simply enter the amounts under the appropriate sections in MyTax. There are specific sections for different types of income. For example, rental income has a section of its own.
