Calculate annual Korean car tax with education surcharge, age discount, and yearly pre-payment discount.

About this tool

Korean Vehicle Tax Calculator computes annual jadongchase. Enter vehicle type (passenger / EV / commercial / van), engine cc or load capacity, first-registration year, and payment timing (Jan/Mar/Jun/Sep prepayment), and the tool applies cc-based unit rate (80~200 KRW/cc passenger) Γ— 30% local education surtax Γ— age discount (5% from year 3, capped at 50% from year 12). The Jan prepayment 9.15% discount is auto-applied so "prepay vs installment" is shown side-by-side. EV/H2 use the flat 130k KRW base; commercial vehicles use load-capacity rates. Numbers cross-check against your WeTax bill. No data leaves your browser.
