US Vehicle Tax Calculator

What it is

US Vehicle Tax Calculator is a free online tool that helps car buyers estimate their out-the-door cost before purchase. It calculates sales tax, title fees, registration costs and DMV charges for all 50 states and Washington DC. Every rate and fee is checked against official sources from state DMV, motor vehicle division and revenue department websites, as well as state statutes. The calculator accounts for state-specific rules like trade-in credits, excise taxes and local rates. Results are estimates only, not legal or tax advice.

Questions from the bench

How do you calculate sales tax on a car?

Multiply the taxable price by your state's rate, then add any city or county rate on top. The taxable price starts with the sale price, but each state decides whether your trade-in, rebates and the dealer's doc fee raise or lower it.

What's included in the out-the-door price?

The out-the-door price is the vehicle price plus the dealer's doc fee, sales tax (or the tax your state charges instead), the title fee and registration and plate fees, minus any trade-in and rebates.

Does a trade-in lower the sales tax on a car?

In many states it does, because tax is charged only on the price minus your trade-in. Some states give no trade-in credit at all, so check your state before you count on it.

Can you legally avoid paying sales tax on a car?

You can't skip a tax your state charges, but you can make sure you don't pay more than you owe. Legal routes are using a trade-in credit where allowed, claiming a gift or family-transfer exemption that applies, and checking whether your purchase is taxable at all.

What are tax, title and license (TTL) fees?

TTL is dealer shorthand for the government charges on a car purchase: the tax, the title fee and license (registration and plate) fees. Dealers usually quote it separately from the vehicle price, so ask for the TTL figure before you agree to a monthly payment.
