Pre-completed tax return

All the pre-completed tax returns are now in MyTax. They arrive by post by the end of April.

In MyTax you can see the tax details in English. The printout that arrives by post is only in Finnish but its content is described here.

  • If there is no need for corrections or additions in your return, 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 2024. You can check the deadline date on your tax return and in MyTax.
  • Self-employed business operators and agricultural operators as well as their spouses: Did you forget to make changes for your tax assessment by the deadline 2 April 2024? See the instructions and report the tax details as soon as you can.

Instructions for filing

When you receive your tax return, this is what you should do:

1

Check the tax return

Always check all the pre-completed data on your tax return. 

2

If everything is correct, you do not need to do anything

If there is nothing to add or correct, you do not have to do anything. If you have not made any changes by the deadline date, we will consider that you have submitted your return with the contents that were pre-completed in it.

3

Correct missing or incorrect details

If there is something that you must add to or correct in your tax return, make the changes in MyTax or file them on paper forms.

See the instructions for filing

The corrections you have made to your tax return in MyTax or on paper forms must arrive at the Tax Administration by the due date stated in your return, at 23.59. You can see the due date on your return’s cover page and in MyTax.

See also instructions for those who submit paper-printed tax forms.

Extended time for filing

You may ask for an extension of time for filing the tax return if you have a valid reason for it. Complete an application form and submit it to the Tax Administration before the deadline date of the tax return. 

You can either

  • log in to MyTax to complete the extension form (Tax matters – Requests – Extended time for filing a tax return) or
  • print the form out on paper, fill it out, and send it to the Tax Administration.
