# Verkeersbelasting — Belgium car tax

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

Belgium's annual circulation tax is a regional charge; this model estimates it from CO2 emission bands.

**Tax year:** 2026

## How it is calculated

Belgium's annual car tax (verkeersbelasting) is set by the region. Flanders uses a formula on engine size, CO2 and euronorm; Wallonia and Brussels use a fiscal-horsepower table.

Electric cars pay a minimal amount. The calculator uses an illustrative CO2 table. Estimate, not tax advice.

## Worked example

With CO₂ of 120, this model computes Jaarlijkse belasting of 280 EUR.

## 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.
