Texas used-car sales tax: a guide for dealers
How Texas motor vehicle sales tax works on a dealer sale, from the 6.25 percent rate and trade-in credit to who remits the tax and by when.
By Dealerspot3 min read
Texas is one of the simpler states for vehicle sales tax: one statewide rate, a full credit for trade-ins, and a clear rule on who collects. The details still trip up new dealers, especially around trade-ins, private-sale values, and the remittance deadline. This guide covers what a licensed Texas dealer needs to know on a typical retail used-car deal.
The rate: 6.25 percent, statewide
Texas motor vehicle sales tax is 6.25 percent of the taxable sales price. Cities and counties do not add their own motor vehicle sales tax, so the rate is the same whether the car sells in Houston or in a small town.
That makes Texas different from states like Alabama or Tennessee, where the buyer's county or city changes the total rate.
What the tax is based on
When a licensed dealer is part of the sale, the Texas Comptroller bases the tax on the sales price, less any trade-in allowance and dealer discounts.
The Comptroller's own example: a buyer purchases a $42,000 vehicle and trades in a vehicle valued at $15,000. Tax is due on the $27,000 difference, so the buyer owes $1,687.50.
| Line | Amount |
|---|---|
| Sales price | $42,000.00 |
| Trade-in allowance | -$15,000.00 |
| Taxable amount | $27,000.00 |
| Tax at 6.25 percent | $1,687.50 |

Trade-ins are credited at their value, not their equity
The trade-in credit is the value of the trade, not the customer's equity in it. If the customer still owes $9,000 on a trade you value at $15,000, the credit is still $15,000. Paying off the lien does not change the tax.
Texas does not cap the trade-in credit, so a large trade can reduce the tax a lot. If the trade is worth more than the vehicle being bought, the taxable amount stops at zero.
Fees and add-ons need a closer look
Whether a charge on the buyer's order belongs in the taxable price depends on what the charge is. Documentary fees, service contracts, and other add-ons are common audit questions. Check the Comptroller's Motor Vehicle Tax Guide or your tax professional for how each item on your buyer's order should be treated, and set it up the same way on every deal.
Standard presumptive value does not apply to dealer sales
Buyers sometimes ask about standard presumptive value (SPV), because Texas uses it on private-party sales. In a private sale, tax is based on the greater of the price paid or a percentage of the vehicle's SPV.
The Comptroller is clear that SPV procedures do not apply when a licensed dealer is a party to the sale. That includes consignment sales by licensed dealers. On your deals, tax is based on your sales price.
Who collects, and the deadline
Texas-licensed dealers must collect motor vehicle tax on taxable retail sales, including cash deals. You do not send it to the Comptroller directly. You remit it to the county tax assessor-collector when you title and register the vehicle, using the title application (Form 130-U) signed by the purchaser.
The deadline is 30 calendar days from the sale, or 60 calendar days for sales to active-duty military buyers. If a dealer does not remit, the county must notify the Comptroller, so missed deadlines tend to come back as penalties and audits.
A few exceptions to keep in mind:
- Dealers do not collect motor vehicle tax on vehicles over 11,000 pounds gross weight. The buyer pays the tax.
- Sales to buyers who will title the vehicle in another state follow different rules. Confirm the treatment before you finish the deal.
A quick checklist for every Texas deal
- Start from the agreed sales price.
- Subtract dealer discounts and the full trade-in value.
- Apply 6.25 percent. There is no local rate to add.
- Decide, once and consistently, how each fee and add-on is taxed.
- Collect the tax and get Form 130-U signed.
- Remit to the county tax assessor-collector within 30 calendar days.
