Routine Williamson County Registration Renewals May Work at Neighborhood Locations
Some Williamson County shops can renew your vehicle tags. They cannot transfer a title or register a new resident's car. Your notice must show Williamson County. Tags can be no more than nine months late, and you must not have an expired-tag ticket.
Bring the notice and proof of current liability insurance. Cars that need an emissions test must pass within 90 days. The test covers gas vehicles aged two through 24 years. Diesel and electric vehicles are exempt.
Use the county's list to find a renewal shop. A lost notice, title problem, or renewal outside these limits goes to the Tax Office or TxDMV instead.
