2026 EV purchase subsidy: when you buy a new electric passenger car, a national subsidy (국고보조금) and a separate local-government subsidy (지방자치단체 보조금) are paid out. The national subsidy is scaled by vehicle performance and price — generally up to about 650만 원 — and the local subsidy (지방보조금) added on top varies widely by where you live (applications close once each municipality's budget runs out). Cars priced under 5,300만 원 get the full amount, those from 5,300만 원 to under 8,500만 원 get only 50%, and anything above that is excluded. Not every buyer receives the same amount, and schemes can close early once the budget is spent — so we show the subsidy separately and do not fold it into the total cost shown above.
