State Car Sales Tax Rates in 2026

Thought you finally negotiated the perfect price on your new car, only to see the out-the-door number inflate by thousands of dollars in the finance office? You are not alone. When budgeting for a new or used car, the sticker price is only part of the equation. One of the largest, unavoidable additional costs is your state car sales tax. Depending on where you live, sales tax can decimate your budget. Here is exactly what you need to know.

How Car Sales Tax Works

Sales tax is typically calculated based on the purchase price of the vehicle. However, in many states, this is calculated minus the value of any trade-in. This means that trading in your old car can significantly reduce your tax burden.

Calculate Your Total Cost

To see exactly how your state's sales tax impacts your monthly payment and total out-of-pocket costs, use our Auto Loan Calculator and enter your local tax rate. If you are debating between buying and renting long-term, plug these tax numbers into our lease vs buy car calculator to ensure your math is bulletproof.

Remember that the base rates above are only the starting point — most states let counties stack their own surtax on top. Ohio is a good example: the 5.75% state rate climbs to a combined 6.5%–8% depending on the county, so an Ohio buyer should check the true local figure with the Ohio sales tax calculator before finalizing any car budget.
