Short answer

Texas taxes vehicle sales at 6.25%, no local add-ons. Texas taxes the price after the trade-in is deducted. Texas exempts out-of-state buyers only under specific conditions: the vehicle must not be used in Texas except for transportation directly out of state and must not be registered in Texas; the buyer issues the dealer Form 14-312 at the time of sale Texas credits sales tax legally paid to another state, so the same dollars are not taxed twice. That summary is for a retail purchase from a dealer, and most states apply different rules to leases and private-party sales.

From the desk

Texas runs the cleanest flat math in the country until the paperwork meets the county. One statewide rate on vehicles, but every deal clears through the county tax assessor-collector and webDEALER, so the desk lives by the county's calendar, not Austin's.

Selling to an out-of-state buyer in Texas

Texas exempts out-of-state buyers only under specific conditions: the vehicle must not be used in Texas except for transportation directly out of state and must not be registered in Texas; the buyer issues the dealer Form 14-312 at the time of sale[2]

The form doing the work here is Form 14-312, Texas Motor Vehicle Sales Tax Exemption Certificate – For Motor Vehicles Taken Out of State, completed at delivery. A missing form becomes the dealer's tax bill, not the buyer's.

The desk's job doesn't end at the tax line. Somebody still has to chase the title, the temp tag, and the buyer's home-state registration, and Voltra's title tracking keeps that chase on one screen.

Buying in Texas from out of state

If you live in another state and buy in Texas, the deciding rule is where the vehicle gets registered: your home state's tax applies at registration, and what happens at the Texas sale depends on the row above. Texas credits sales tax legally paid to another state, so the same dollars are not taxed twice.[1]

Registration and temp tags

Someone moving to Texas has 30 days from the move to register the vehicle, handled through the county tax assessor-collector's office.[5] Since July 1, 2025 (HB 718), Texas dealers issue metal license plates at the time of sale instead of paper temporary tags.
