New Residents
Moved to El Paso? Register Your Vehicle Within 30 Days
New Texas residents must register their out-of-state vehicle within 30 days of moving, and El Paso's emissions test requirement applies right away.
Did you just move to El Paso from another state? Texas law says you must register your vehicle here within 30 days. El Paso is an emissions-inspection county. That means you must pass an emissions test before you can register your car.
Go to the El Paso County Tax Office. Bring your out-of-state title, proof of Texas liability insurance, and your Vehicle Identification Number (VIN). Moving from another Texas county? The process is similar. Check the TxDMV 'New to Texas' page for the full list of what you need to bring.
