Texas Auto TTL Calculator

When you purchase a vehicle in Texas, you owe more than just the sticker price. The state requires payment of tax, title, and license (TTL) fees before you can legally drive your new vehicle on public roads. Understanding these costs helps you budget accurately and avoid surprises at the county tax office.

Motor Vehicle Sales Tax (6.25%)

Texas charges a flat 6.25% motor vehicle sales tax on the purchase price of all vehicles. Unlike general sales tax, there is no additional local rate — the 6.25% applies statewide regardless of which city or county you live in. For dealer purchases, you can subtract your trade-in value before the tax is calculated. For example, if you buy a $35,000 vehicle and trade in one worth $10,000, you only pay tax on $25,000.

Standard Presumptive Value (SPV) Rule

For private-party sales, Texas uses the Standard Presumptive Value system to prevent tax avoidance. The tax is calculated on the greater of the actual sale price or 80% of the vehicle's SPV (determined by TxDMV based on year, make, model, mileage, and condition). If you pay significantly less than market value, you may still owe tax on the SPV-based amount. You can look up your vehicle's SPV on the TxDMV website before purchasing.

Title and Registration Fees

The title fee is $28 in most counties or $33 in emissions-testing counties. The base registration fee is $50.75, plus $4.75 for processing and handling and $1.00 for insurance verification. Local county fees average around $20 but vary by county. Initial registrations also include a state inspection fee of $16.75, while renewals pay $7.50.

Emissions Counties

Texas designates certain counties as emissions-testing areas where vehicles must pass an emissions inspection in addition to the standard safety inspection. These counties include Harris, Dallas, Tarrant, Travis, El Paso, Collin, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, and Williamson. If you're relocating to the Dallas or Fort Worth area, your vehicle will need to pass emissions testing. Vehicles registered in these counties pay a higher title fee ($33 vs. $28) to cover the additional emissions program costs.

Electric Vehicle (EV) Fee

Starting in 2023, Texas charges a $200 annual fee for all-electric vehicles at each registration or renewal. This fee is designed to offset the gas tax revenue that EV owners do not contribute, since Texas uses fuel taxes to fund road construction and maintenance. Plug-in hybrids (PHEVs) are not currently subject to this fee — only fully battery-electric vehicles.
