Title and registration after buying a used car in Texas

Updated September 29, 2026 · 5 min read

Buying the car is only half the job: it has to be titled and registered in your name. How much of that you do yourself depends on who you bought from. The official source for everything below is the Texas Department of Motor Vehicles (TxDMV); rules and fees change, so check there before you go.

If you buy from a dealer

A Texas dealer normally files the title and registration for you and collects the sales tax and fees as part of the sale. You drive away with temporary tags while the paperwork goes through. Make sure the out-the-door price you agreed on includes these charges, keep copies of everything you sign, and follow up with the dealer if your registration hasn't arrived before the temporary tags expire.

If you buy from a private seller

You file the paperwork yourself, at your county tax assessor-collector's office. In Harris County, that's the Harris County Tax Office.

What the seller should do

A private seller should file a Vehicle Transfer Notification with TxDMV (it can be done online) as soon as the car is sold. It records that the car is no longer theirs, which protects them from tickets and tolls you run up afterwards.

Inspections

Texas's inspection rules changed in recent years, and whether your car needs an emissions test depends on the county it's registered in; Harris County is one of the counties with emissions testing. Check the current rules on TxDMV's site for your county before registering.

Before any of this, check the car itself: our guide on checking a car's history by VIN shows how to spot a branded title before you buy.
