Annual vehicle tax calculator 2026
The Finnish annual vehicle tax (ajoneuvovero) consists of a base tax (perusvero) and a driving-power tax (käyttövoimavero). The base tax is set by the CO2 emission (WLTP or NEDC) from the tax table, or by total mass if no emission value is registered; in 2026 it ranges from 106.21 € to 654.44 € per year. The driving-power tax applies to all non-petrol cars, based on fuel type and total mass. This calculator shows both parts and the yearly total.
For example, a 1,734 kg electric car taken into use in 2022 pays 171.17 € (base tax) + 124.83 € (driving-power tax) = 296.00 € per year. The calculator is indicative — the exact tax is set by Traficom.

The calculator is indicative and applies to a passenger car (2026). It calculates the base tax from the current tax tables and the driving-power tax at the levels effective 1.1.2026. Vans, trucks, motorhomes and certain special cases are taxed differently. The exact tax is set by Traficom. This is not a tax decision.
How is the vehicle tax calculated?
The annual vehicle tax (ajoneuvovero) consists of a base tax (perusvero) and a driving-power tax (käyttövoimavero). The base tax is based on the CO2 emission (WLTP or NEDC) from the tax table; if no emission value is registered, it is based on the car’s total mass. In 2026 the lowest base tax is 106.21 € and the highest 654.44 € per year. An electric or hydrogen car’s base tax is 106.21 € (taken into use before 30.9.2021) or 171.17 € (1.10.2021 or later). The driving-power tax applies to all non-petrol cars: cents per day per each started 100 kg (diesel 5.5, electric 1.9, petrol plug-in hybrid 0.95, diesel plug-in hybrid 3.6, gas 3.1 cents), multiplied by 365 days.
What makes up the annual vehicle tax?
The base tax is based on the car’s carbon dioxide emission: the higher the CO2, the higher the tax. In 2026 low-emission cars (0–103 g/km WLTP) have the lowest base tax, 106.21 € per year, rising in steps to 654.44 € (400 g/km or more). Cars taken into use before 2001 have no CO2 value, so their base tax is calculated from total mass (170.82–580.35 € per year).
An electric or hydrogen car’s base tax is fixed: 106.21 € per year if the car was taken into use before 30.9.2021, and 171.17 € per year if taken into use on 1.10.2021 or later. This difference is worth noting — many calculators show only one of the two figures.
The driving-power tax applies to every car that runs on something other than pure petrol. It is calculated from the maximum permissible total mass: cents per day per each started 100 kg. For passenger cars, the rates from 1.1.2026 are diesel 5.5, electric 1.9, petrol plug-in hybrid 0.95, diesel plug-in hybrid 3.6 and gas 3.1 cents. The mass is rounded up to the next hundred kilograms, and the daily tax is multiplied by 365.
The vehicle tax is not the same as the car tax: the vehicle tax is paid yearly for as long as the car is in traffic use, whereas the car tax (autovero) is a one-time tax on a car’s first registration. Traficom collects the vehicle tax and sends the tax bill automatically.
Frequently asked questions
How much is the vehicle tax on an electric car in 2026?
An electric car’s base tax is 106.21 €/year (taken into use before 30.9.2021) or 171.17 €/year (1.10.2021 or later). On top of that, the driving-power tax is 1.9 cents/day per each started 100 kg. For example, a 1,734 kg electric car taken into use in 2022 pays 171.17 € + 124.83 € = 296.00 €/year.
What are the base tax and the driving-power tax?
The base tax is based on CO2 emission (or mass) and applies to passenger cars and vans. The driving-power tax (the so-called diesel tax) applies to cars running on anything other than petrol and is based on total mass. A petrol car pays only the base tax.
Where do I find the CO2 emission and measurement method?
They are shown on the vehicle tax bill, the registration certificate, or Traficom’s Oma asiointi service. The bill states whether the NEDC or WLTP table is used. If no emission value is registered, the tax is based on mass.
How is the driving-power tax calculated?
Driving-power tax = cents/day × number of started 100 kg × 365 / 100. The total mass is rounded up to the next hundred kilograms. For example, an 1,800 kg diesel car: 18 × 5.5 cents × 365 = 361.35 € per year.
Why is the tax based on mass instead of emissions?
Passenger cars taken into use before 2001 have no EU-approved CO2 value, so the base tax is calculated from total mass (170.82–580.35 € per year). The same applies to other cars with no registered emission value.
How does the vehicle tax differ from the car tax?
The vehicle tax (ajoneuvovero) is an annual tax that Traficom bills for as long as the car is in traffic use. The car tax (autovero) is a one-time tax paid only when a car is first registered. They are separate taxes.
