Car Sales Tax by State: Rates, Trade-In Credit and Local Taxes

Car sales tax is charged by the state where you register the vehicle, at a state rate that runs from 0% to 7.75% as of November 2026, plus local tax in many states. Alaska, Montana and New Hampshire have no state tax on car purchases, while Connecticut charges 7.75% on most vehicles priced above $50,000. Most states tax the price after subtracting your trade-in.

On a $40,000 car, the gap between a 4% state and a 7% state is $1,200, before any city or county tax. That is why the tax line on an out-the-door quote is worth checking.

How much is sales tax on a car in each state?

The table lists the state-level rate on motor vehicles from the Florida Department of Revenue’s Motor Vehicle Sales Tax Rates by State chart, dated February 11, 2026. It does not include city, county or district taxes, which can add several points in some states.

Rates change, and a few states adjusted theirs in 2025. Confirm the current figure with your state revenue department or DMV before you sign.

Which states use a title tax instead of sales tax?

Roughly ten states and DC charge a separate titling or excise tax on vehicles in place of regular sales tax. Georgia uses a title ad valorem tax, North Carolina a highway use tax, New Mexico a 4% motor vehicle excise tax, and Delaware a document fee collected at titling.

Maryland is a good example of why the label matters. It lists no sales tax on cars, but its titling excise tax is 6.5% since July 1, 2025, according to the Maryland MVA. For the buyer, a title tax works much like a sales tax: it is a percentage of the price, paid when the car is titled.

Oregon has no general sales tax but charges a vehicle use tax on new vehicles. Alaska has no state tax, though some boroughs and cities collect local sales tax on purchases.

Is trade-in value deducted before tax?

In most states, yes: tax is charged on the sale price minus the dealer’s trade-in allowance. With a $40,000 car and a $15,000 trade-in, you pay tax on $25,000 in those states.

A few states limit or deny the credit. California, Virginia and Oklahoma have taxed the full price with no trade-in credit. Michigan allows a credit up to a dollar cap that rises each year. Ohio has allowed the credit only when a new car is bought from a new-car dealer. Rules on leases, private sales and trade-ins of leased cars also differ, so ask your state revenue office how your deal will be taxed.

If you sell your old car privately instead of trading it in, you usually lose this tax saving. Compare the private sale price with the trade-in offer plus the tax you would save.

How do local taxes change the total?

Local sales taxes are added on top of the state rate in most states that tax car sales, and they are usually based on the address where the car will be registered. California, for example, starts at 7.25% statewide and adds district taxes that vary by city and county.

Some states tax vehicles at a different rate than other goods, or cap the tax. South Carolina charges 5% but no more than $500 per vehicle. West Virginia charges a flat $30 on vehicles that sell for under $500. Illinois applies a separate private party vehicle use tax to sales between individuals.

What if I buy a car in another state?

You generally pay tax to the state where you register the car, not the state where you bought it. Many dealers collect your home state’s tax and send the paperwork, and most states give credit for tax already paid to another state so you are not taxed twice.

1. Tell the dealer where the car will be registered before the contract is written.
2. Ask whether the dealer will collect your home state’s tax or whether you will pay it at your DMV.
3. Keep the bill of sale showing any tax paid, since your state may give credit for it.
4. Check your state’s rules on credit for out-of-state tax. Florida’s chart, for example, notes that Arkansas, Mississippi and West Virginia do not give credit for tax paid to Florida.

Buying in a no-tax state does not avoid tax if you register the car at home. Our guide to transferring a car title covers the DMV steps.

Is sales tax charged on dealer fees and private sales?

Whether dealer fees are taxed depends on the state. Some states tax the doc fee and some add-ons as part of the sale price, while others exempt them; our table of dealer doc fees by state shows the separate caps on that fee.

Private sales are taxable in most states that tax car purchases, and the tax is paid at the DMV when the buyer titles the car. Texas taxes private used-car sales on the higher of the price paid or the vehicle’s standard presumptive value, so writing a low price on the bill of sale does not lower the tax.

Bottom line

Look up the rate for the state where the car will be registered, add local tax, and check whether your trade-in reduces the taxable price. Then compare the tax line on each dealer’s written out-the-door figures rather than the advertised price.

FAQ

Do I pay sales tax on a used car?

Yes, in most states. Used cars bought from a dealer or a private seller are taxed at the same state rate as new ones in most states, though some states use a book value instead of the price for private sales.

Can I include sales tax in my car loan?

Usually yes. Many lenders let you finance tax, title and registration, but that adds interest and can leave you owing more than the car is worth early in the loan.

Is car sales tax deductible on my federal return?

It can be if you itemize and choose to deduct state and local sales taxes instead of income taxes. Check the current IRS rules or ask a tax professional for your situation.

Do leased cars get taxed differently?

Often yes. Many states tax each monthly lease payment rather than the full price, while a few tax the full value up front. Ask the leasing company how your state handles it.
