Filing and payment instructions for a period-specific car tax return

If you are a registered filer of car tax on new vehicles, submit a period-specific car tax return on the new vehicles once a month.

A period-specific car tax return must be filed for each calendar month. You must file a return even if you have not registered any new vehicles during the period in question.

How to file a car tax return

File a period-specific car tax return by the 10th day of the month following the period. If it falls on a holiday or weekend, you can file the return on the next business day.

You can file the car tax return in MyTax or via Vero API, the Tax Administration’s interface service. Read more about how to grant an authorisation for e-filing.

How to file in MyTax – instructions

Vero API

You can file on paper only if there is a special reason – for instance if electronic filing is impossible due to technical difficulties. You can find the link to the form at the bottom of the page.

If you file the return late, you may have to pay a late-filing penalty or a punitive tax increase (in Finnish and Swedish only, link to Finnish).

How to make corrections to the return

If you notice an error in your tax return, file the return again. The new tax return replaces the previous filing.

You can file the return again in MyTax or via Vero API. Note that you do not have to use the same service through which you originally filed the return. If you file via Vero API, give the identifier included in the Tax Administration’s acknowledgement of your original tax return. You can also check the identifying data on the tax return in MyTax.

If you have already received a car tax decision, you can make a claim for adjustment. Read instructions for making a claim for adjustment.

How to pay car tax

After you have received your car tax decision, pay the tax in MyTax or in your online bank. You can find the payment information (such as the Tax Administration’s bank account number and the reference number for car tax) in the period’s car tax decision and in MyTax.

Use the reference number for car tax.
