Texas Motor Vehicle Tax: 6.25%, No Local Add-On
Texas charges a flat 6.25% motor vehicle tax statewide — unlike general sales tax, which stacks city, county and transit rates up to 8.25% in places like Houston or Dallas. Your car’s tax rate doesn’t change no matter which Texas county you live in. What changes the amount you owe is which of five transaction types applies, since each one is taxed differently under Texas law.
Private-Party Sales and the SPV Rule
Buy from a dealer, and tax applies to the price you actually paid. Buy from a private individual — a neighbor, a family friend, a Marketplace seller — and Texas doesn’t just trust the number on your bill of sale. It taxes you on whichever is higher: your stated price, or 80% of the vehicle’s Standard Presumptive Value (SPV), a regional average the state publishes for every make and model.
Example: you pay $25,000 for a used truck privately. Its SPV is $34,000, so 80% of that is $27,200 — higher than what you paid. Texas taxes you on $27,200, not $25,000. You can look up your vehicle’s SPV at TxDMV.gov and enter it in the “Advanced” section above. If your car is genuinely worth less (damage, high mileage), a certified appraisal within 30 days can override the SPV figure.
Trade-Ins, Gifts and Even Trades: What’s Taxed Differently
- Dealer purchase with a trade-in: your trade-in value is subtracted before tax is calculated. Trade a $5,000 car against a $30,000 purchase, and you’re only taxed on $25,000.
- Still owe money on your trade-in? That doesn’t change your tax — Texas still credits the trade-in’s full value. But the payoff amount gets added to your new loan, so if you owe more than the trade is worth, that negative equity increases what you finance.
- Private-party purchase: no trade-in credit exists. The SPV rule applies regardless of what you traded.
- Gift between immediate family (spouse, parent/child, sibling, grandparent): a flat $10 transfer tax, not 6.25%.
- Even trade between two owners, no cash changing hands: a flat $5 transfer tax.
New Texas Residents: The $90 Flat Tax
Moving to Texas with a vehicle you already own and already paid tax on? You don’t pay 6.25% again. Texas charges a flat $90 new-resident use tax instead, as long as the vehicle was registered in your name in your previous state.
Title, Registration and County Fees, Explained
- Title fee: $28 in most counties, $33 in emissions-testing counties (Harris, Dallas, Tarrant, Travis, Collin, Denton, Fort Bend, and a few others). One-time, charged only when a vehicle is newly titled — not on renewals.
- Registration: $50.75 base, plus $13.25 in mandatory statewide fees (insurance verification, processing, and the inspection-replacement fee that took over when Texas dropped its annual safety inspection sticker in 2025).
- County road & bridge fee: varies by county, typically $11.50-$21.50. This calculator defaults to $11.50; adjust it if you know your county’s rate.
- New plates: a one-time $7.50.
Electric Vehicles: The $200 Surcharge
Texas charges EV owners an extra $200 a year, on top of standard registration, to make up for the gas tax EVs don’t pay. New EV registrations are issued for two years, so the first payment is actually $400 upfront — after that, it renews annually at $200.
FAQs
Does trade-in value reduce my Texas car tax?
Only on dealer purchases. Private-party sales use the Standard Presumptive Value rule instead, and trade-in doesn’t apply there.
Why is my car taxed at 6.25% when my county’s sales tax is 8.25%?
Because Texas motor vehicle tax is separate from general sales tax. It’s a flat 6.25% statewide with no city, county or transit add-on — unlike the tax on everyday purchases.
What is Standard Presumptive Value (SPV)?
It’s the state’s estimate of a used vehicle’s average regional resale value. For private-party purchases, Texas taxes you on your price or 80% of the SPV, whichever is higher, to prevent underreporting sale prices.
How much does it cost to title a car in Texas?
$28 in most counties, $33 in emissions-testing counties, plus a $7.50 plate fee. Both are one-time charges on a new title, not on renewals.
Do I pay tax on a gifted car in Texas?
Only $10 flat, if the gift is between immediate family under Transportation Code §152.025. A sale between family members at a below-market price is still taxed as a regular sale.
Is there an extra fee for electric vehicles in Texas?
Yes, $200 a year. Since new EV registrations run for two years, the first bill is $400.
Financing in Texas?
Once you know your real monthly payment, see how it compares against insurance before you sign — Texas premiums vary a lot by county. And if you’re cross-shopping two vehicles, the car comparison calculator shows total cost, not just sticker price.
Data note: Rates reflect the Texas Comptroller of Public Accounts and TxDMV fee schedules as of September 2026. County road & bridge fees vary by county; confirm yours before a large purchase.
