# MTV Hesaplama — Turkey motor vehicle tax

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

Turkey's MTV is a base amount set by engine-size band, scaled down by an age factor as the car gets older.

**Tax year:** 2026

## How it is calculated

The MTV (motorlu tasitlar vergisi) is Turkey's annual car tax, paid in two instalments. The base amount depends on engine displacement band and, for newer cars, the car's value tier.

An age factor reduces the tax as the car gets older. The official tariff is revalued every January by the revaluation rate, so the annual refresh matters here. Illustrative rates. Estimate, not tax advice.

## Worked example

With Motor hacmi of 1,600, this model computes Yıllık MTV of 4,000 TRY.

## 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.
