How car sales tax works in Texas
Texas keeps vehicle tax simple. There's one motor vehicle sales tax of 6.25%, charged on the sales price minus your trade-in allowance. The Texas Comptroller's Motor Vehicle Tax Guide also says that rebates passed directly to you, whether from the manufacturer or the dealer, reduce the taxable value. So a trade-in and a rebate both cut your tax bill.
When you buy from a dealer, the dealer collects the tax and sends it to your county tax assessor-collector along with your title application (Form 130-U). For used cars bought from a private seller, the tax may be based on the car's standard presumptive value instead of the price.
Worked example
Without the trade-in and rebate, the tax would be 6.25% of $35,000, or $2,187.50. The trade-in and rebate together save $687.50 of tax, on top of reducing what you borrow.
Texas rules to know
- One rate. The Comptroller lists a single 6.25% motor vehicle sales tax rate, so there's no local rate to enter.
- Trade-ins count. The trade-in allowance comes off the sales price before tax.
- Rebates count too. Manufacturer and dealer rebates passed to you reduce the taxable value.
- Private sales differ. Standard presumptive value can set the taxable amount for private-party used cars.
- Fees are separate. Title and registration are paid to the county and aren't included.
Planning your Texas car loan
With a flat rate and generous credits, the biggest levers in Texas are the price, your trade-in value and your loan rate. Get a pre-approval before visiting the dealer, then compare total interest across terms in the main car loan calculator. Longer terms lower the payment but add interest, and the car loses value while you pay. Our personal loan calculator can help if you're comparing an unsecured loan.
Trade-in or private sale in Texas?
Because Texas taxes the price minus your trade-in, a trade-in is worth its value plus 6.25% of that value in tax saved. A $10,000 trade-in saves $625 of motor vehicle sales tax, so a private sale only comes out ahead if it brings in more than about $10,625, and you'd still have to find a buyer and handle the title transfer yourself.
Rebates work the same way: a $1,000 rebate passed to you lowers the taxable price, saving $62.50 of tax on top of the rebate itself. When you compare dealers, ask for the price after rebates and before tax, then let the calculator work out the 6.25%.
