# Automaks 2026: mootorsõidukimaksu kalkulaator — Estonia car tax

Source page: https://valem.run/calculators/estonia/car-tax

Estonia's new car tax is an annual charge plus a one-time registration tax, both built from a base amount, the CO₂ above 117 g/km and the mass above 2,000 kg.

**Tax year:** 2026

## How it is calculated

Estonia introduced a motor-vehicle tax in 2025, which makes it a topical, high-interest search. The annual tax is a 50 EUR base plus 3 EUR for every gram of CO₂ above 117 g/km and 0.20 EUR for every kilogram of mass above 2,000 kg.

A one-time registration tax works the same way from a 300 EUR base plus 5 EUR per gram of CO₂ above 117 g/km. The calculator shows both, plus the first-year total.

Rates here are illustrative of the 2025 structure and belong in the model's constants for easy refresh against the official EMTA calculator. Not tax advice.

## Worked example

With CO₂ emissions of 150, this model computes First-year total of 614 EUR.

## Inputs

## What this page claims

The Valem engine reproduces this model's formula through 2 self-test cases. That shows internal consistency, not that the formula matches current law; the cited sources are the evidence for that. Estimate, not tax advice.
