How car sales tax works
Most states charge sales tax, or a special vehicle tax that replaces it, when you buy a car and register it. The tax is usually paid at the dealer or when you title the car at the DMV, and it is based on the state where you register the car, not where you buy it. Three things decide how much you pay:
- The rate: a state rate, often plus a county or city rate.
- The trade-in rule: most states tax only the price minus your trade-in, but California, Virginia, Hawaii and a few others tax the full price, and Michigan caps the credit.
- Special rules: caps (South Carolina's $500), local tax only on part of the price (Florida, Tennessee), or a different tax altogether (Georgia's TAVT, North Carolina's highway use tax).
Car sales tax formula
Sales tax = taxable amount × (state rate + local rate)
Worked examples: $35,000 car with a $10,000 trade-in
- Texas: taxed on $25,000 at 6.25% = $1,562.50.
- California (9.03% average combined rate): no trade-in credit, so taxed on the full $35,000 = $3,160.50.
- South Carolina: 5% of $25,000 would be $1,250, but the fee is capped at $500.
- North Carolina: 3% highway use tax on $25,000 = $750.
Vehicle sales tax by state (2026)
State rate is the state-level tax that applies to vehicles. Local rate is the average local add-on where one applies; your exact rate depends on your address.

Tips to pay less tax on a car
- Trade in instead of selling privately in states with a trade-in credit: the tax saving can be worth hundreds of dollars.
- Know which rate applies: it is the rate where you register the car, so buying in a cheaper county usually does not help.
- Ask whether dealer fees are taxable in your state; doc fees often are.
- Budget for the tax: use the car loan calculator to see the payment with tax rolled in, or check the car affordability calculator first.
Frequently asked questions
How do I calculate sales tax on a car?
Subtract the trade-in credit your state allows from the price, then multiply by your state and local rate. A $35,000 car with a $10,000 trade-in in Texas is taxed on $25,000 at 6.25%, or $1,562.50.
Which states have no sales tax on cars?
Montana, New Hampshire and Alaska have no state sales tax on vehicles, though some Alaska cities charge local tax. Oregon has no sales tax but charges a 0.5% privilege tax on new cars from dealers, and Delaware charges a 5.25% document fee.
Does a trade-in reduce sales tax?
In most states yes, the tax is charged only on the price minus the trade-in. California, Virginia, Hawaii and DC give no credit, Michigan caps it at $12,000 in 2026, Ohio allows it only on new cars and Kentucky only on used cars.
Do I pay sales tax where I buy the car or where I live?
Generally where you register it, which is usually where you live. If you buy out of state, the dealer may collect your home state's tax, or you pay it when you title the car at home.
Do I pay sales tax on a used car from a private seller?
In most states yes, usually when you title the car at the DMV. Some states have different rates or rules for private sales, such as Illinois, which uses a separate tax table.
