Car Sales Tax by State

A car is usually not taxed at your state's general sales tax rate. Most states tax vehicles under a special rule of their own: a different rate, a different treatment of your trade-in, sometimes a cap or a minimum, and in a few states a tax on a value the state assigns rather than the price you paid. Pick your state below for the rule that actually applies, with the official source linked.

Why the general sales tax rate is the wrong number

Rate tables built for ordinary retail sales give the combined state, county and city rate for a ZIP code. Cars break those tables in both directions. In some states the vehicle tax is a flat statewide rate with no local tax added, so the retail table overstates it, sometimes by a lot. In others the full local stack applies to a car, and the trade-in you were counting on earns no credit, so two common assumptions fail at once. And a few states do not use the purchase price as the tax base at all. The only safe source for a state's vehicle rule is the state itself, which is why every entry above links to the official revenue or DMV page it came from.

The four things that decide your tax

The rate, which for vehicles is often a special rate: lower than the general rate in many states, higher in a few, and replaced by a flat fee or an excise tax in others. The basis: most states tax the price you paid, but some tax a value the state assigns, so a bargain price does not always lower the tax bill. The trade-in credit: most states tax only the price above your trade-in, but some tax the full price, and a few credit only certain purchases or cap how much credit you can take. Caps and minimums: some states cap the tax no matter what the car costs, and some charge a minimum even on a cheap one. Your state's particular combination of the four is what the lookup above shows when you pick it.

When the state sets the value

A handful of states do not tax the price on your paperwork. They tax a value the state itself assigns, drawn from its own assessment tables or a published valuation guide, and that value can come out higher or lower than what you actually paid. If your state works that way, your state's entry above links the official calculator or value lookup the state provides. Run it, and tax the value it returns. If you would rather work from your own estimate, you can do that too. The choice is yours: this page will not prefill an estimate and present it as the state's figure.

About these figures

Every rate, rule and cap in this lookup was taken from an official state source: a department of revenue, a DMV, or the state code, and each state's entry links to the pages used. The figures were verified in November 2026, including a second pass through the official sites to settle every field where state pages conflicted with each other; where two official sources still disagree, the entry follows the governing statute and says so in its notes, which appear when you select that state. Local taxes, where they apply, change with the county you register in; use the official local table linked in your state's entry, and treat your deal sheet as the final word for a specific purchase.
