What is Korean auto tax?
Auto tax is a local tax levied annually on vehicle ownership. For non-commercial passenger cars, the rate scales by engine displacement with cutoffs at 1,000cc and 1,600cc. From the third year, the tax is reduced by 5% per year up to 50%. A 30% education surtax is added on top. EVs and hydrogen vehicles pay a flat 130,000 KRW regardless of size.
Non-commercial passenger car rates
| Displacement | Rate |
|---|---|
| Up to 1,000cc | 80 KRW/cc |
| 1,001 – 1,600cc | 140 KRW/cc |
| Over 1,600cc | 200 KRW/cc |
| Electric / Hydrogen (flat) | 130,000 KRW (flat) |
| Education surtax | 30% |
Age reduction
Year 3: 5% / Year 4: 10% / ... / Year 12+: 50%. Reduction grows by 5 percentage points each year and is capped at 50% — vehicles 12+ years old pay half.
Frequently asked questions
- When is auto tax due?
- Twice a year: H1 (Jan–Jun) is billed in June, H2 (Jul–Dec) in December. Paying the full year in January earns a discount (around 5–7% depending on the year).
- How is vehicle age counted?
- From the first registration date — not the model year. A car registered in May 2023 is in its third year by June 2026, qualifying for a 5% reduction.
- Do hybrid cars get an EV-style discount?
- No — the hybrid auto-tax exemption ended after 2023. Hybrids now pay the same combustion-engine cc rates and are treated as combustion in this calculator.
- How big is the January full-year discount?
- Discount rates change yearly (5% in 2024, 7% in some 2025 windows). Check Wetax (wetax.go.kr) for the current rate. This calculator shows the standard pre-discount amount.
Reference only. Covers non-commercial passenger cars. Commercial vehicles, trucks, and vans use different rate tables and are not modeled here. New-vehicle pro-rated first-year tax, the January full-year discount, and any local-government additional reductions are not applied. Confirm the actual amount on Wetax or your vehicle registration.
