How to declare with paper forms - pre-completed tax return
You can use MyTax to make corrections to your pre-completed tax return. If you do not have the opportunity to make corrections online, you can authorise someone else to file the tax return in MyTax on your behalf.
If you make your corrections by using paper forms, the required form numbers are stated on your tax return next to each pre-completed entry. Do not attempt to enter the corrections in the A4 printout that you received to your home address. For example, you must use two different forms to claim the tax credit for household expenses, and to report any rental income you have received. See a list of all paper forms.
The forms for corrections must arrive at the Tax Administration by the due date printed on your return. To avoid a penalty payment for late filing, we recommend that you send us the necessary corrections well in advance of the due date.
Send the completed forms to their return address
The return address for these forms is
Finnish Tax Administration
P.O. BOX 700
You can ask for a return envelope together with the forms by telephone or at the tax office. You can also use your own envelope. In that case, remember to buy a postal stamp.
Do not enclose any receipts or other documentation with the forms – if necessary, we will contact you to ask for them later. Read more about the requirements for how receipts should be stored.
Send the forms well in advance of the due date
Make sure to get the correction forms early and allow enough time for their postal delivery back to the Tax Administration. If you do not send us your corrections on time, you may have to pay a late-filing penalty.
Please take account of the following:
- The written entries will be read by computer, by optical character recognition. For this reason, make sure your entries stay inside each field of the form. Do not fasten the paper forms together with a stapler.
- Only fill in forms printed out on tax.fi, or forms you have picked up at the local tax office. Do not use photocopies. Photocopied forms may have inferior quality, making optical character recognition difficult.
- Remember to enter your name and personal ID on all pages.

What you have reported on paper forms will be displayed in MyTax
If you send us information on paper, the same information will later be displayed in MyTax. You can see it in MyTax after the Tax Administration has saved the content of your paper forms. This process may take as long as two weeks.
