# Калкулатор данък МПС — Bulgaria car tax

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

Bulgaria's car tax is a municipal charge: engine power in kW times a power-band rate times an age and eco coefficient.

**Tax year:** 2026

## How it is calculated

Bulgarian car tax is set by the municipality and built from engine power in kilowatts. The per-kW rate rises with a power band, and an age-and-emission coefficient adjusts the total.

Newer, cleaner cars pay less through the eco coefficient; older cars pay a higher factor. Rates are illustrative and vary by municipality. Estimate, not tax advice.

## Worked example

With Мощност of 75, this model computes Годишен данък of 59.05 EUR.
