Short answer. Buy from a licensed dealer or a private seller who holds the title in their own name, run the VIN for recalls and title brands, get an inspection, and file the title at the Guadalupe County tax office within 30 days. Guadalupe County is not on the Texas emissions program list, so no emissions test is required to register there.

Guides for Seguin, TX buyers
Texas rules that apply in Seguin, TX
- Title transfer deadline. In a private sale, the buyer must title the vehicle in their name within 30 days from the date of sale. The seller gives the buyer a properly signed title (with date of sale and odometer reading) and a signed Form 130-U showing the sales price, and the buyer files at the county tax assessor-collector office.
- Sales tax. Texas motor vehicle sales tax is 6.25 percent of the sales price minus any trade-in allowance. In a dealer sale, the dealer collects the tax and remits it to the county; in a private sale, the buyer pays the county tax assessor-collector when titling.
- New to Texas. New residents have 30 days from moving to Texas to register their vehicle, and must get a Texas driver license within 90 days of moving to the state.
- Inspection. Under House Bill 3297, non-commercial vehicles no longer need a safety inspection to register, starting January 1, 2025. Instead, all non-commercial vehicles pay a $7.50 inspection program replacement fee at registration; vehicles never registered before pay $16.75 to cover the first two years.
