The District doesn't charge sales tax on vehicles — it charges a titling excise tax with rates set by vehicle weight and fuel efficiency, not a flat percentage of price. Lighter and more efficient vehicles pay lower rates; heavier, thirstier ones pay more, with electric vehicles historically favored. Our calculator uses a simplified flat rate as an approximation, so treat its DC tax line as a ballpark: your actual excise depends on your specific vehicle's class, and the DMV's schedule is the final word.
Two structural notes: there's no trade-in credit — the excise applies to full fair value regardless of trade — and 'fair value' is the operative phrase, since DC calculates on book value where it exceeds the claimed price. Full-price treatment puts DC in the same club as Maryland and Virginia next door, making the whole capital region a place where trade allowances must win on equity alone.
Doc fees are uncapped, typically $300–500. Cross-border shoppers take note: buying in Maryland or Virginia doesn't dodge the DC excise — the District collects it when you title at home, based on its own schedule. Shop the metro for price and selection freely; just run the tax math as a DC resident either way.
Every figure above was last verified against official District of Columbia sources in August 2026. Tax rules do change — the final word is always your paperwork and the DMV.
