Car tax calculator

How the annual tax is built

The M1 rate combines a €50 base, stepped CO₂ component and gross-mass component above a threshold. N1 normally combines a €50 base and CO₂ component; the fully electric N1 base is €30. The age coefficient reduces only the CO₂ and mass components, never the base.

Category exceptions in 2026

An M1/M1G vehicle with 8 or 9 seats uses the N1 rate from 2026. An M1 motorhome also uses the N1 rate. An N1 vehicle with high specific power may move to the M1 rate; engine power and payload are needed for that check.

When the CO₂ value is missing

Without WLTP or NEDC data, the Act derives a reference CO₂ value from engine power, kerb mass, age, fuel and hybrid type. The calculator therefore asks for those technical fields and shows no approximate number if they are missing.

Registration and first ownership change

777.ee does not reproduce this fee formula. Technical data or, at the user's choice, a plate/VIN is sent to the public Transpordiamet API. The identifier is not stored or added to 777.ee analytics. The API does not determine exemptions.

Scope and effective date

The local rules version is effective from 1 January through 31 December 2026. The result is a full-year rate; a vehicle first registered during the year may have a lower official tax due to daily proration. Exemptions and the aggregate child reduction across a person's vehicles are excluded.

Examples

• M1: 150 g/km and 2,100 kg

  For a new vehicle the base is €50, the CO₂ component €99 and mass component €40. With an age coefficient of 1.00, the full-year rate is €189.

• Eight-seat M1

  In 2026 an M1 vehicle with 8 or 9 seats uses the N1 rate. The same CO₂ and mass can therefore produce a different result from the ordinary M1 formula.
