Pre-completed tax return

In March or April 2019, you will receive a pre-completed tax return. We will send them to individual taxpayers by letter, and only in the national languages Finnish and Swedish. However, you can check all your tax return information in English in MyTax. 

If you find there is no need for corrections or additions, you do not have to do anything. If you want to make corrections, the deadline for them is 7 May, 14 May or 21 May 2019. You can check the date valid for you on your paper tax return and in MyTax.

Tax return will change

The tax return has a new layout. Please note that for most taxpayers, the dates when the Tax Administration pays refunds and when the taxpayers’ back taxes fall due will be earlier in 2019. Read more about the upcoming changes.

Let us know some of your tax-return information already now in MyTax

You can submit part of your 2018 tax return in MyTax already now. The information you can enter and save already now includes for example deductible travel expenses, the credit for household expenses, any deductions for a second home in another district because of your work, information on rental income, information on capital gains and losses from the sale of property (other than corporate stock and securities). See a list of items that you can enter in MyTax at the present time.

How to file returns

File in MyTax
File on paper


From now on, the date of payment of your refund will depend on the end date of your tax assessment. The Tax Administration will pay the next refunds to most individual taxpayers in August 2019 (instead of December). To check your tax refund – how much you receive and when – see your assessment decision or log in to MyTax later in the spring.

Back tax

From now on, the due dates of any back taxes you may have will depend on the end date of your tax assessment. The majority of individual taxpayers must pay their 2018 back taxes earlier than before, because the first instalment will fall due already in August 2019. The exact amount and instructions for payment will be in MyTax. You can also pay your back tax in MyTax.

Tax decision

The section on the paper form headed “Verotuspäätös” or “Beskattningsbeslut” (=tax decision) contains the result of your assessment for the year.
