Texas Vehicle Sales Tax Calculator (2026)

Drop in your numbers. Use SPV only for private-party purchases (leave $0 for dealer). Trade-in reduces taxable basis only on same-dealer transactions.

Texas taxes vehicle sales separately from general sales tax. The Motor Vehicle Sales Tax rate is a flat 6.25% — only the state portion, with no local city, county, or transit authority add-ons. The total is the same whether you buy in Houston, Dallas, Austin, or Marfa.

• Rate: 6.25% of taxable value (state only)
• Base for purchases from licensed dealers: Sale price (minus trade-in allowance, if same transaction)
• Base for private-party purchases: Sale price OR Standard Presumptive Value (SPV) published by the Texas Department of Motor Vehicles, whichever is higher
• When paid: At your county tax assessor-collector's office during title transfer, within 30 calendar days of purchase
• Late penalty: 5% if 1-30 days late, 10% if 31+ days late, additional $25 within first 30 days of delinquency

The 30-day rule is strict. Texas has aggressively cracked down on title-jumping and late title transfers — both because of consumer protection (titles in seller's name expose buyers) and revenue protection. Plan to handle title transfer within 30 days of purchase. Your county tax office can process this in person; some offer online services.

For private-party vehicle purchases (not from a licensed dealer), Texas applies the Standard Presumptive Value (SPV) system to prevent underreporting of sale prices. The SPV is the TxDMV-published "going rate" for a make/model/year/condition combination, refreshed quarterly using third-party data (NADA Guides, Kelley Blue Book, etc.).

When you transfer title from a private party, the county tax office calculates tax on the higher of:

• The sale price you actually paid (per the bill of sale)
• The Standard Presumptive Value (80% of the published SPV)

Worked example: you buy a 2022 Ford F-150 from a private party for $25,000. The TxDMV SPV for that vehicle is $34,000. The 80% SPV = $27,200. Since $27,200 > $25,000, tax is calculated on $27,200 × 6.25% = $1,700.

Two ways to dispute SPV-based tax if you genuinely paid less:

• Certified appraisal from a licensed motor vehicle dealer or insurance adjuster: If you can show that the vehicle's actual condition (high mileage, body damage, mechanical issues) reduces its value below the SPV, you can use the appraisal as the tax basis. Costs $100-$300 typically.
• Trade-in adjustment: If the SPV calculation produces a result that's obviously wrong (e.g., the SPV doesn't reflect a known recall or design issue), the county tax office can sometimes override.

For typical fair-market transactions, the SPV produces a close approximation of the actual price. For genuinely below-market deals (private estate sales, family transfers between non-immediate family, etc.), the appraisal route protects you from over-paying tax.

Texas allows trade-in vehicles to reduce the taxable amount on a same-transaction purchase. The math:

• If you buy from a licensed dealer: Sale price MINUS trade-in allowance = taxable amount × 6.25%
• If you sell privately and buy from a different dealer: No trade-in adjustment. You pay tax on the full purchase price.
• If both transactions are with the same dealer: Trade-in reduces the taxable base.

Worked example: you trade in a vehicle worth $18,000 at a dealer toward a new vehicle priced at $42,000. Taxable amount: $42,000 - $18,000 = $24,000. Tax: $24,000 × 6.25% = $1,500.

Compare to selling the trade-in privately for $20,000 (a higher price than the dealer trade-in offer), then buying the new vehicle from the dealer for $42,000. You'd net $20,000 from the private sale but pay tax on the full $42,000 = $2,625. Net after-tax: $20,000 - $2,625 = $17,375. Trading at the dealer net: $18,000 - $1,500 = $16,500.

In this scenario, the private sale wins by $875. But the math depends on how much more (or less) you can get privately vs. the dealer's trade-in offer. For many buyers, the convenience of trading at the dealer + the tax savings makes the dealer trade-in the right answer. Run the math both ways.

• Gifts between qualifying family members (spouse, parent, child, grandparent, grandchild, sibling, child's spouse, parent's spouse): flat $10 tax. Both parties complete Form 14-317.
• Inherited vehicles: No motor vehicle sales tax owed when transferring title from the deceased to a beneficiary. Complete Form VTR-262 (Affidavit of Heirship) or work through probate.
• Out-of-state vehicles brought into Texas by a new Texas resident: $90 "New Resident Tax" if no tax was previously paid in another state. If you can demonstrate that you paid sales tax to your prior state at 6.25% or more, you may owe nothing additional.
• Vehicles purchased by businesses: Same 6.25% rate. Trade-in adjustments apply. Section 179 federal depreciation may be available but doesn't affect Texas sales tax owed.
• Leased vehicles: Texas taxes the upfront cost of the lease (capitalized cost reduction + first month's payment + other upfront amounts) at the time of lease origination. Monthly payments do not include sales tax — this is opposite of how many states tax leases.
• Disabled veteran vehicles: One vehicle per qualifying disabled veteran is exempt from sales tax, but only if titled in the veteran's name and meeting specific Texas DMV requirements.

The 6.25% rate is straightforward but the special situations can save (or cost) hundreds to thousands of dollars. Most county tax offices have specialists for unusual situations — call ahead if you're facing an inheritance, gift between non-immediate family, or out-of-state move with multiple vehicles.

Scenario 1 — New car, Houston dealer, $45,000 price, no trade-in: Tax = $45,000 × 6.25% = $2,813. Same total whether bought in Houston, Dallas, or El Paso.

Scenario 2 — Used car, private party in Austin, $22,000 sale, SPV $28,000: Tax basis = max($22,000, $28,000 × 80% = $22,400) = $22,400. Tax = $22,400 × 6.25% = $1,400. Note the 80% SPV adjustment.

Scenario 3 — New car with trade-in at Dallas dealer: $52,000 purchase, $19,000 trade-in. Taxable = $33,000. Tax = $2,063. Without trade-in: $3,250. Trade-in saves $1,188 in tax.

Scenario 4 — Mom gifts her son her old Honda Civic worth $14,000: Tax = $10 (flat gift rate between immediate family). Without the gift exception, would have owed $875.

Scenario 5 — New Texas resident moves from Colorado with a 2024 Tesla Model Y: Paid Colorado sales tax of 7.75% at original purchase. Texas New Resident Tax = $90 flat (since Colorado tax exceeded Texas's 6.25%). No additional MVST owed.
