Where to register your vehicle in San Antonio

Vehicle registration in San Antonio is handled by the Bexar County Tax Assessor-Collector's office, not by a separate DMV. You can register at any of their locations across the county, but the main office is at 411 North Frio Street in downtown San Antonio. They also operate satellite offices in different parts of the county — locations and hours are listed on the Bexar County Tax Assessor-Collector website.

You can also renew registration by mail or online through the county website if you are renewing an existing registration and have not had any changes to your vehicle or address. New registrations and transfers require an in-person visit.

Walk-in service is available, but wait times vary by location and time of day. The office is typically less crowded early in the morning on weekdays. You can also schedule an appointment through their website to reduce wait time.

Documents you need to bring

For a new registration, bring your vehicle title (the original or certified copy), a valid government-issued ID, and proof of residency. Proof of residency can be a utility bill, lease agreement, or mortgage statement dated within the last 60 days. You will also need proof of insurance — your insurance company can provide a declarations page or ID card showing your policy is active.

If you are registering a vehicle you just purchased, bring the bill of sale along with the title. If the title is held by a lender, you will need written permission from the lender to register the vehicle, or the lender may need to be present. Check with the Tax Assessor-Collector office before you go if you are unsure about your title situation.

For a renewal, you typically only need your renewal notice (mailed to you) and payment. If you are renewing online or by mail, you do not need to bring anything in person.

Registration fees and how they are calculated

Texas registration fees are based on your vehicle's gross vehicle weight rating (GVWR) — the maximum weight the vehicle is designed to carry, not what it actually weighs. Heavier vehicles cost more to register. Fees also depend on whether your vehicle is a passenger car, truck, motorcycle, or specialty vehicle.

The Bexar County Tax Assessor-Collector website has a fee calculator where you can enter your vehicle information and see the exact cost before you register. Fees typically range from around $50 to $300 for standard passenger vehicles, but this varies based on weight and age. You can pay by cash, check, debit card, or credit card at the office.

If you are registering a vehicle for the first time in Texas, you may also owe a one-time motor vehicle sales tax based on the purchase price. This is separate from registration fees. The Tax Assessor-Collector can tell you whether sales tax applies to your situation.

How long registration takes and when it is valid

If you register in person at the office, you will receive your registration sticker and documents the same day. Your registration becomes valid when ready once you pay and receive your sticker. If you register by mail, allow 7 to 10 business days for processing and delivery.

Registration validity depends on your vehicle type. Most passenger cars are registered for two years, while some vehicles (like certain trucks or specialty vehicles) may be registered for one year. Your renewal notice will tell you when your registration expires. You can renew up to 60 days before expiration without penalty.

If your registration expires, you cannot legally drive the vehicle on public roads in Texas. Driving with expired registration can result in a traffic citation and fine. Renew before the expiration date shown on your registration sticker.

Renewing your registration by mail or online

If you are renewing an existing registration and have not moved or changed your vehicle, you can renew by mail or online through the Bexar County Tax Assessor-Collector website. You will need your renewal notice (the form mailed to you about 60 days before expiration) and payment information.

Online renewal is the fastest option — you can complete it in a few minutes and your new sticker will be mailed to you within 7 to 10 business days. Mail renewal takes longer because your payment and forms have to be processed after they arrive. Do not wait until the last week before expiration if you are using mail renewal.

You cannot renew online or by mail if you have changed your address, changed your vehicle's information, or if your registration has already expired. In those cases, you must visit the office in person.

What to do if your registration is expired or lost

If your registration sticker is lost or damaged, you can request a replacement at the Tax Assessor-Collector office. Bring your vehicle title and ID. Replacement stickers are issued the same day and cost a small fee (usually under $10).

If your registration has already expired, you can still renew it in person at the office. Bring the same documents you would bring for a new registration: title, ID, proof of residency, and proof of insurance. You will pay the standard registration fee plus a late fee. The amount of the late fee depends on how long the registration has been expired — the longer it has been, the higher the fee.

Do not drive the vehicle on public roads while it is expired. If you are stopped by police, you will receive a citation. If the vehicle needs to be driven to the registration office, you can request a temporary permit from the Tax Assessor-Collector that allows you to drive to the office and back home.

Special situations: transfers, out-of-state vehicles, and commercial registration

If you are transferring registration from another vehicle you own, or if you are registering a vehicle you just moved to Texas from another state, you must visit the office in person. Bring your out-of-state title or your previous Texas registration, your new title (if applicable), proof of residency, ID, and proof of insurance.

Commercial vehicles, trailers, and motorcycles have different registration requirements and fees. Motorcycles, for example, are registered annually rather than biennially. Trailers and commercial vehicles may require additional documentation. Call the Tax Assessor-Collector office or check their website for the specific requirements for your vehicle type.

If you are registering a vehicle that was previously registered to someone else in Texas, you will need to transfer the title into your name first. This is done at the same office and requires the signed title from the previous owner, your ID, and proof of residency.

Frequently Asked Questions

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

No. New registrations and transfers require an in-person visit to the Bexar County Tax Assessor-Collector office. You can only register online if you are renewing an existing registration with no changes to your vehicle or address.

What happens if I drive with an expired registration?

You can receive a traffic citation and fine from law enforcement. The amount of the fine varies, but expired registration is a moving violation in Texas. You will also owe a late fee when you renew your registration at the office.

How do I know what my vehicle's gross vehicle weight rating is?

The GVWR is printed on a label inside the driver's side door jamb or on the vehicle's frame. You can also find it in your owner's manual or by contacting your vehicle's manufacturer. The Tax Assessor-Collector office can also help you find this information if you bring your vehicle title.

Can I register a vehicle if the title is held by a bank or lender?

Yes, but you will need written permission from the lender or the lender may need to be present. Contact your lender before you go to the office to find out what documentation they require. Some lenders can provide a letter authorizing registration; others may require a representative to sign off in person.

How far in advance can I renew my registration?

You can renew up to 60 days before your registration expires without penalty. Renewing early is a good idea if you are using mail renewal, since it takes 7 to 10 business days. If you renew after the expiration date, you will owe a late fee in addition to the standard registration fee.
