In Texas, car buyers face a 6.25% state auto sales tax, with local taxes adding up to a total rate of around 8.25% in Austin, Dallas, and Houston, as the Texas Comptroller’s Office reported.
These costs can catch buyers off guard, especially when combined with fees for title transfers and private sales.
This guide dives into everything you need to know about Texas auto sales tax—from calculating tax on trade-ins to understanding unique scenarios like Standard Presumptive Value (SPV) for private sales—helping you prepare for the real costs of buying a vehicle in Texas.
Current Texas Sales Tax Rate
State Tax: Texas charges a 6.25% tax on all vehicle purchases.
Local Add-Ons: Depending on the city or county, additional local taxes might be applied. These are usually less than 2%, making the maximum combined rate around 8.25%.
Types of Auto Sales Taxes and Fees
When purchasing a vehicle in Texas, you'll have to pay your auto sales tax in Texas as per the following calculations:
Sales Tax: This is applied to new and used vehicle purchases within Texas.
Use Tax: A use tax applies for cars bought outside Texas but brought into the state.
New Resident Tax: If you’re a new Texas resident bringing a car from another state, a one-time $90 fee applies.
Special Considerations in Tax Calculation
Calculating tax on private sales or used cars has unique requirements in Texas.
Standard Presumptive Value (SPV): When buying a used vehicle from a private seller, Texas uses the SPV (an estimated market value) to calculate tax. This prevents the underreporting of vehicle values.
Documentation Fees: Many dealers charge fees for handling title and registration. These aren’t state taxes but can range from $50 to $150.
Rebates and Trade-In Deductions
There are potential savings for buyers who qualify for trade-in deductions or rebates:
Rebates: The tax calculation occurs after rebate deductions, reducing the taxable amount.
Trade-Ins: Texas exempts the value of a trade-in vehicle from the sales tax calculation. For instance, if your trade-in is valued at $5,000, and you’re buying a car priced at $20,000, you only pay tax on the $15,000 balance.
Payment Deadlines for Sales and Use Tax
Timely tax payment is essential when purchasing a vehicle.
Dealer Sales: Taxes on dealership purchases are collected and paid directly by the dealer.
Private Sales: Buyers in private transactions must pay the sales tax at the county tax office within 30 days of the sale.
New Residents: If you bring a car to Texas, you have 30 days after establishing residency to pay the one-time $90 fee.
Example Tax Calculations
Let’s consider how taxes might apply in different scenarios:
Dealership Purchase: For a $25,000 new vehicle, expect a 6.25% state tax, totaling $1,562.50 (plus any local taxes).
Private Sale Using SPV: Buying a $10,000 used car from a private seller means calculating tax on the SPV, which may differ from the actual purchase price.
Trade-In Example: Trading in a $7,000 car toward a $20,000 purchase means you’re taxed only on the $13,000 balance.
Exemptions and Exclusions
Certain vehicles or situations allow for tax exemptions:
Non-SPV Vehicles: Vehicles like older models, heavy trucks, or specialty vehicles may qualify for alternative tax calculations.
Sales Exemptions: Military personnel, diplomatic representatives, or certain nonprofit organizations may be exempt from auto sales tax under specific conditions.
Where and How to Pay the Tax
Paying the auto sales tax can differ based on your purchasing method.
Dealership Purchases: Dealers usually collect the sales tax and handle title processing for you.
County Tax Office: For private sales, visit your local county tax office to file the paperwork and pay the tax. Bring the title, bill of sale, and payment.
