Pre-completed tax returns

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.
