Car Stamp Duty by State — Calculators & 2026-27 Rates
Stamp duty, or motor vehicle duty, is the one-off tax you pay when a car is registered to a new owner. Every state charges it, but no two work it out the same way: some use a single flat rate, some tier it by value, and some load or discount it by the car's emissions or engine.
The tax is calculated on the vehicle's dutiable value, and the detail that catches buyers out is how the tiers apply. In some states a higher rate only touches the slice of value above a threshold; in others, crossing a threshold lifts the rate on the entire price. A small difference in what you pay for the car can move the duty by a surprising amount, so it pays to know which kind of scale your state uses.
