You will receive a pre-completed tax return by post in March or April. The tax return contains data on previous year's income, taxes and deductions. The final taxation is determined on the basis of the tax return data.
Check the information in the tax return.
If the tax return information is correct and no details are missing, you do not have to do anything else.
If the information needs to be corrected or supplemented, report the changes in MyTax or on paper forms. The tax return in MyTax or the paper forms must be received by the Tax Administration no later than the due date entered in your tax return. You can see the due date on the front page of your tax return and in MyTax.
The service is free of charge.
