How do you calculate sales tax on a car?
Car sales tax = taxable price × (state rate + local rate). In most states the taxable price is the vehicle price minus your trade-in value, plus any taxable dealer fees. A $35,000 car with a $10,000 trade-in in Texas (6.25%) is taxed on $25,000 plus a $150 taxable doc fee: $1,571.88 in tax. Without trade-in credit you’d pay tax on the full price.

| Trade-in | −$10,000.00 |
| Taxable doc fee | $150.00 |

| Sales tax (6.25%) | $1,571.88 |
| Title & registration | $300.00 |
| Out the door ($25,000 + $150 + $1,571.88 + $300) | $27,021.88 |
The trade-in credit alone saves $625 in tax (6.25% of $10,000). These are the calculator’s defaults.

Ways to legally reduce car sales tax
- Trade in rather than sell privately in states with trade-in credit — compare the tax saving with the higher private-sale price.
- Ask which fees are taxable. Doc fees are taxable in some states and not others.
- Register in your actual home county; tax is generally based on where the vehicle is registered, not where you buy it.
- Understand rebates: in many states, manufacturer rebates don’t reduce the taxable price, while dealer discounts do.
Tax is paid once, but depreciation continues every year — estimate it with the Car Depreciation Calculator.
