# 자동차세 — South Korea car tax

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

South Korea's car tax is engine displacement times a per-cc rate, plus a 30% local-education surtax.

**Tax year:** 2026

## How it is calculated

South Korea's automobile tax is engine displacement in cc times a per-cc rate (80 won up to 1,000 cc, 140 to 1,600, 200 above), plus a 30% local-education surtax.

An age discount of 5% per year applies from the third year, capping at 50% from year twelve — the calculator now applies it, so enter the age of the car as well as its displacement. Estimate, not tax advice.
