# Taxe véhicule Luxembourg — car tax calculator

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

Luxembourg's annual vehicle tax scales with CO2 emissions and fuel type.

**Tax year:** 2026

## How it is calculated

Luxembourg's annual car tax is based on CO2 emissions times a fuel factor and a progressive multiplier that rises with emissions.

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 Taxe annuelle of 57.60 EUR.

## Inputs

The Valem engine reproduces this model's formula through 3 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.
