Instructions for filling in the period-specific car tax return in MyTax

This guidance describes how you can submit a registered car tax filer’s period-specific car tax return in MyTax or on paper. Please note that you can use the paper form only for a special reason.

Also note that you must file a return for every tax period, even if you have no vehicles to report. The car tax period is always the calendar month.

File in MyTax

How to complete the return

If you have vehicles to report for the period, select “Yes” at “Are there registered vehicles to report for this tax period?”. Add the vehicle’s details by clicking “Add vehicle”. See below for more information on what details to report.

If you have no vehicles to report for the period, select “ No” at “Are there registered vehicles to report for this tax period?”. You can submit details up to 6 months in advance.

If you submit the details on paper, tick the option “Vehicle-specific details” and list the details on a free-form enclosure. Give the required details separately on each vehicle.

Vehicle details

Vehicle identification number

Enter the vehicle identification number (VIN) in the same format as it is in the transport register. The VIN usually consists of 17 characters, and it may contain special characters. The VINs of EU and EC type-approved vehicles usually do not have the letters o, i or q, because these may be easily mistaken for numbers.

The VIN is a unique code for identifying the vehicle. It is stated in the official documents of the vehicle. Vehicles are specified by the VIN in the transport register.

Price source

Report the price code, commercial title or other price source.

Report the price code that was valid on the date when the vehicle’s price was determined.

The price code is a unique code for the vehicle model, determined by the company. The vehicle importer or manufacturer must provide the Tax Administration with information on their commercially available vehicle models. The information must be itemised by price code. Read more about reporting the price code.

Report and specify the commercial title, i.e. the vehicle identifier, if details of a commercial title confirmed by the Tax Administration have been used in tax calculation. The commericial title can be used until a new price code is adopted for the vehicle or the vehicle is no longer on sale.

  • Commercial title refers to the vehicle identifier that consists of 10 numbers and specifies the model of the vehicle. The identifier usually starts with the numbers 1100.
  • Report the commercial title that was valid on the date when the vehicle’s price was determined.

Select Other price source if the price code reported to the Tax Administration or the commercial title confirmed by the Tax Administration has not been used in the tax calculation.

Registration details

Enter the vehicle’s date of registration in Finland. The date of registration must be during the tax return period.

Report the date when the price was determined.

If an order and sales contract for the vehicle was made before the date of registration and a recommended retail price exist for the vehicle on the contract date, report the contract date as the date when the price was determined. Otherwise, report the vehicle’s date of registration in Finland as the date when the price was determined.

Reduced tax on van

If you are requesting reduced tax for your van, select Yes for “Is the vehicle a van that is subject to reduced car tax?”.

Tax exemption

If you are requesting tax exemption for the vehicle, select Yes for “Is the vehicle exempted from tax?” and select the basis for tax exemption.  

If you report the vehicle as a taxi exempt from tax, state the traffic licence number.
