Where to register your vehicle in San Antonio

In San Antonio, you register your vehicle at the Bexar County Tax Assessor-Collector's office, not at a state DMV — Texas has no DMV. The Tax Assessor-Collector handles vehicle registration, title transfers, and renewal for all Bexar County residents. You can visit in person, mail documents, or use online renewal for some transactions.

The main office is located at 411 W. Commerce Street, San Antonio, TX 78205. Bexar County also operates satellite offices in different parts of the county if the downtown location is inconvenient. Hours are typically Monday through Friday, 8 a.m. to 5 p.m., though you should confirm current hours on the Bexar County website before you go, since hours can shift seasonally.

If you are registering a vehicle for the first time in Texas, you will need to visit in person or mail your documents. Online renewal works only if you already have an active Texas registration and are renewing before your current registration expires.

Documents you need for a new registration

For a new vehicle registration in San Antonio, bring or mail the original title or a bill of sale if you do not yet have the title. The title must show your name as the owner, or if you are buying from a private seller, the bill of sale must be signed by the seller and include the vehicle's VIN, make, model, year, and the sale price. If the vehicle is financed, the lienholder's name will appear on the title.

You also need proof of identity — a valid driver's license, passport, or state ID card — and proof of residency. Proof of residency can be a utility bill, lease agreement, mortgage statement, or insurance policy dated within the last 60 days and showing your San Antonio address. A current vehicle inspection is required; the inspection must have been completed within the last 12 months and shows that your vehicle meets Texas safety and emissions standards.

Bring proof of insurance as well. Texas requires all registered vehicles to carry liability insurance, and you will need to show the insurance card or a declaration page with your policy number, the vehicle's VIN, and the coverage dates. If you are registering a vehicle you just bought, your insurance company can issue a temporary proof of coverage by phone or email while you wait for the physical card.

Registration fees and taxes in San Antonio

Texas registration fees are based on the vehicle's weight and age. A new or newer vehicle typically costs between $50 and $90 for a one-year registration, while older vehicles may cost less. The exact amount depends on the gross vehicle weight rating (GVWR) listed on your title or registration.

San Antonio adds a local tax on top of the state fee. This local tax varies depending on whether your vehicle is a passenger car, truck, motorcycle, or commercial vehicle. The combined state and local cost for a typical passenger car ranges from $60 to $120 for a one-year registration, though you should ask the Tax Assessor-Collector for the exact amount for your specific vehicle before you go.

Some vehicles are registered for two years instead of one. If your vehicle qualifies for a two-year registration, the total cost will be roughly double the one-year amount. You can ask whether your vehicle is may be able to access when you contact the office or visit in person.

How to register by mail or online

If you are renewing an existing registration and your vehicle has no outstanding violations or safety issues, you can renew online through the Bexar County Tax Assessor-Collector website. Online renewal requires your current registration number and the last four digits of your VIN. You pay the renewal fee by credit or debit card, and your new registration is mailed to you within one to two weeks.

To register by mail, send your completed process (Form VTR-130-U, available on the Bexar County website), proof of inspection, proof of insurance, and a check or money order to the Tax Assessor-Collector's office. Include a self-addressed, stamped envelope if you want your documents returned. Mail processing typically takes two to three weeks, so plan ahead if your registration is expiring soon.

New registrations cannot be completed online or by mail — you must visit the office in person or have someone with power of attorney represent you. If you cannot visit in person, you can authorize a family member or friend to register the vehicle on your behalf if you provide them with a signed power of attorney form and all required documents.

Vehicle inspection requirements before registration

Before you register your vehicle in San Antonio, it must pass a Texas vehicle inspection. The inspection checks that your vehicle meets state safety and emissions standards — brakes, lights, windshield wipers, horn, seat belts, and emissions systems all have to work. The inspection is valid for 12 months from the date it is completed.

You can get an inspection at any licensed inspection station in Texas, not just in San Antonio. Many auto repair shops, tire shops, and gas stations offer inspections. The inspection costs between $25 and $50 depending on the station. Bring your vehicle keys and proof of ownership (title or registration) to the inspection.

If your vehicle fails inspection, the station will tell you what needs to be fixed. You can take the vehicle to a repair shop, have the work done, and return to the same or a different inspection station for a retest. Once your vehicle passes, you receive an inspection certificate that you bring to the Tax Assessor-Collector when you register.

Renewing your registration in San Antonio

Your registration renewal notice is mailed to you 60 to 90 days before your registration expires. The notice shows your current registration number, the renewal fee, and instructions for renewing online, by mail, or in person. You can renew up to 60 days before your registration expires without penalty.

If you renew online, you need your current registration number and the last four digits of your VIN. The fee is charged to your credit or debit card, and your new registration card is mailed within one to two weeks. If you renew by mail, send the renewal notice with a check or money order to the address shown on the notice.

If you miss your renewal important date, you can still renew, but you will owe a late fee in addition to the regular registration fee. Driving with an expired registration is illegal in Texas and can result in a traffic ticket. If your registration has been expired for more than two years, you may need to re-register as if it were a new registration, which requires an inspection and all original documents.

What to do if you move to or from San Antonio

If you move to San Antonio from another state, you have 30 days to register your vehicle in Texas. You will need your out-of-state title or registration, proof of identity, proof of residency in San Antonio, and a passing Texas vehicle inspection. The out-of-state title will be surrendered, and you will receive a Texas title and registration.

If you move out of San Antonio or out of Texas, you should notify the Bexar County Tax Assessor-Collector so your registration address is updated. If you move to another Texas county, you can transfer your registration to that county's tax assessor-collector. If you move out of state, you will need to register your vehicle in your new state and may be able to surrender your Texas registration for a refund of unused fees.

If you move within San Antonio but your address changes, you can update your registration address online through the Bexar County website or by visiting the office in person. Bring your current registration card and proof of your new address.

Frequently Asked Questions

Can I register my vehicle online if I just bought it?

No. New registrations must be done in person at the Bexar County Tax Assessor-Collector's office or by mail with a power of attorney. Online renewal works only if you already have an active Texas registration for that vehicle.

What if my vehicle inspection expires before my registration does?

Your registration remains valid, but you cannot renew it until you have a current inspection. Get a new inspection completed, then renew your registration before the important date to avoid late fees.

Do I need to bring my vehicle to the Tax Assessor-Collector's office?

No. You only need to bring documents and proof of inspection. The vehicle itself does not need to be present for registration, though you will need the VIN from your title or bill of sale.

How long does registration take if I go in person?

In-person registration typically takes 15 to 30 minutes if you have all required documents. Wait times can be longer during peak hours, usually mid-morning and mid-afternoon on weekdays. Going early in the week or early in the morning often means shorter waits.

What happens if I register a vehicle that is not mine?

You cannot register a vehicle unless you are the owner or have a signed power of attorney from the owner. The title or bill of sale must show your name as the buyer or owner. Registering a vehicle you do not own is fraud.
