How to submit a Declaration of use in MyTax

  1. MyTax opens on the Your tax types tab. Select the tab Tax matters.

  2. Click the Activities relating to car tax link under Car tax.

  3. Select the Declaration of use link.

  4. Please check that the names, etc. are right (for the Filer and for the person who provides further information). After that, go to Vehicle details, the next stage.

  5. Fill in the VIN number, whether the vehicle is new or used, date of first registration, odometer reading at the start of use in Finland, vehicle category, make and model, and the start date of use in Finland. Proceed to Preview and send.

  6. Please re-check all the information. Click Edit or Previous to make any corrections. You can select Save as unfinished if you want to come back later to complete the Declaration. Your entries are kept saved for 3 months. The Tax Administration will not process the data before you have submitted it. When everything is correct, click Submit.

  7. You get a confirmation letter with an acknowledgement of receipt of your Declaration. This confirmation letter gives you the right to operate the vehicle on the road.

    You can see the Declaration (a pdf file) in MyTax. Print it out on paper, to be kept in your vehicle when you drive it. Go to the Communication tab and then click the See decisions and letters link under Decisions and letters.

  8. After you have got the confirmation letter of your Declaration of vehicle use, you can go to the submittal of a Car tax return. To do so, press the File car tax return button. All the entries you made on the Declaration of use will show pre-filled on the Car tax return.
