Car Sales Tax Calculator
Estimate the sales tax on a new or used car, with trade-in credit, rebates and dealer fees, and the out-the-door price. Ten states' vehicle rules are built in and sourced; every other state uses its general rate.
Your numbers
The rate is the state's vehicle rate where we checked it, otherwise its general sales tax rate.
The agreed price before trade-in and rebates.
Dealer documentation fee and add-ons sold with the car. Leave out registration, title and plate fees.
Usually the rate where you live or register the car. Check your state's rate lookup.

How to use the car sales tax calculator
- Choose the state where the car will be registered. Where we checked the state's vehicle rules, the rate, the trade-in rule and any caps fill in for you.
- Type the agreed price, the trade-in value, any rebate and the doc fee. Leave out registration, title and plate fees: they are not sales tax.
- Add the local rate for the buyer's home address if the state charges one. The field disappears in states where vehicles carry no local tax.
- Read the tax, the taxable amount and the out-the-door price. Override the trade-in or rebate setting if the deal is a private sale or the rebate goes to the buyer.
How car sales tax is worked out
Taxable amount = price + taxable fees − trade-in (if the state credits it) − rebate (if the state does not tax it). Tax = taxable amount × (state rate + local rate). Some states add caps: Florida's county surtax applies to the first $5,000, Arkansas's local tax to the first $2,500 and Tennessee's local tax to the first $1,600.
Worked examples: Texas, $30,000 car, $150 doc fee, $10,000 trade-in: $20,150 × 6.25% = $1,259.38, no local tax. California, $30,000 car, $85 doc fee, $5,000 trade-in, 1.5% district rate: no trade-in credit, so $30,085 × 8.75% = $2,632.44. Tennessee, $30,000 car, $5,000 trade-in, 2.25% local: $1,750 state + $36 local + $44 single article tax = $1,830.

Checked October 2, 2026 on each state's revenue or motor vehicle site. Georgia's rate is its title ad valorem tax, North Carolina's its highway use tax. Other states use the general base rate from the sales tax rates by state table.
What the out-the-door price includes
Here the out-the-door price is the vehicle price plus the doc fee and other fees you entered, minus the trade-in and the rebate, plus the tax. It leaves out registration, title, plate and inspection fees, which vary by state and by vehicle, so the dealer's final number will be a little higher.
If the trade-in is worth more than the car, the taxable amount and the out-the-door price stop at zero rather than going negative.
Who uses it
Car buyers use it to check a dealer's buyer's order before signing, or to compare a deal across a state line, since the tax usually follows the address where the car is registered rather than the dealership.
Car sales reps and finance managers use it to give a quick out-the-door figure on the phone or at the desk, and to show a customer what the trade-in saves in tax in states that credit it. For anything that is not a vehicle, use the general sales tax calculator.

The tax is one line on the deal. The conversation is the rest.
The trade-in number, the payment the buyer can live with and what they said about their old car all come up at the desk. ParrotNotes records the conversation (with permission), writes the summary and pulls out the follow-ups, so the next call starts where this one ended.
