Where to register your vehicle in Bexar County
Bexar County vehicle registration is handled by the county tax assessor-collector's office, not by a separate DMV. You register and renew through the Bexar County Tax Assessor-Collector, which operates multiple locations across the county. The main office is in downtown San Antonio, but you can also use branch offices in Converse, Helotes, Leon Valley, and Universal City.
You can also renew your registration by mail or online through the county's website, which is often faster than visiting in person. The online renewal option is available if your vehicle has a current inspection and you have no outstanding violations or liens on the title.

- Mail renewal is available for renewals only; new registrations require an in-person visit with your title and proof of inspection.
- Registration fees in Texas are based on vehicle value and county location, so your cost depends on what your vehicle is worth according to county records.
- You must have a current vehicle inspection before you can register or renew, and inspections are valid for one year from the inspection date.
Documents you need for a new registration
For a new vehicle registration in Bexar County, bring your title (the official ownership document from your previous state or from the dealership), proof of a current vehicle inspection, and proof of identity. If the vehicle is financed, bring the lien holder's information as well — the lender's name and address will appear on your registration.
You also need proof of residency if you are registering a vehicle in Texas for the first time. A utility bill, lease agreement, or mortgage statement dated within the last 60 days works. If you are registering a vehicle you already own in Bexar County after moving from another county in Texas, you still need proof of your new address.
Bring your Social Security number or Individual Taxpayer Identification Number. The tax assessor-collector uses this to set up your account and calculate your registration fee based on the vehicle's value.
How registration fees are calculated
Texas registration fees are not flat rates — they are based on the appraised value of your vehicle according to county records. Bexar County uses a standard formula: the fee is roughly 0.6% of the vehicle's appraised value, though the exact percentage can vary slightly. A vehicle appraised at $20,000 will cost more to register than one appraised at $10,000.
The county tax assessor-collector's office determines the appraised value using industry guides and the vehicle's age, make, model, and condition. You can ask the office what value they are using before you pay. If you believe the appraisal is too high, you can request a review, though this process takes time and requires documentation of the vehicle's actual market value.
Bexar County also charges a county fee on top of the state registration fee. The total cost is the sum of both, so your final bill will be higher than the state portion alone. Ask for an itemized receipt so you can see what portion goes to the state and what portion goes to the county.
Renewing your registration by mail or online
If you are renewing a registration you already have in Bexar County, you can renew by mail or online without visiting an office. Online renewal is the fastest option: log into the Bexar County Tax Assessor-Collector website, enter your vehicle information and current registration number, and pay by credit or debit card. Your new registration should arrive by mail within 5 to 10 business days.
Mail renewal works the same way but takes longer. Send your renewal notice (the document the county mails you before your registration expires) along with a check or money order to the address on the notice. Include a note with your phone number so the office can contact you if there are questions. Mail renewal typically takes 2 to 3 weeks.
Both online and mail renewal require that your vehicle has a current inspection. If your inspection has expired, you must get a new one before you renew. You cannot renew online or by mail if there are outstanding violations on your account or if the county has flagged your vehicle for any reason.
Getting a vehicle inspection before registration
Texas requires all registered vehicles to pass an annual inspection. In Bexar County, you can get an inspection at any licensed inspection station — these are typically independent repair shops, dealerships, or service centers. The inspection checks your brakes, lights, windshield, horn, seat belts, and emissions (for vehicles subject to emissions testing).
An inspection costs between $25 and $50 depending on the station and whether your vehicle is subject to emissions testing. Emissions testing is required in Bexar County for most gasoline vehicles, which adds to the cost. Diesel vehicles and vehicles over 25 years old are typically exempt from emissions testing.
Inspections are valid for one year from the date of inspection. You can get an inspection up to 90 days before your registration expires, so you do not have to wait until the last moment. Once you have the inspection, you can renew your registration when ready — you do not have to wait for your current registration to expire.
What to do if your registration expires
If your registration expires before you renew, you cannot legally drive the vehicle on public roads in Texas. If you are stopped by law enforcement, you will face a traffic citation and a fine. The fine for driving with an expired registration in Texas starts at $100 and can go higher depending on how long the registration has been expired.
If your registration has expired, you can still renew it at any Bexar County Tax Assessor-Collector office. Bring your expired registration, your current vehicle inspection, and your proof of identity. There is no additional penalty fee for renewing after expiration — you straightforward pay the standard renewal fee. However, if you were cited for expired registration, you will need to handle that traffic ticket separately through the court system.
If you know your registration is about to expire, renew early. Online renewal takes only a few minutes, and mail renewal takes less than three weeks. Both are faster and easier than dealing with an expired registration.
Frequently Asked Questions
