Where to register your vehicle in Bexar County

In Bexar County, you register your vehicle through the Bexar County Tax Assessor-Collector's office, not through a separate DMV. The Tax Assessor-Collector handles vehicle registration, renewal, and title work for the entire county. You can register in person at one of their offices, by mail, or online through their website.

The main office is located in downtown San Antonio, but Bexar County also operates satellite locations in different parts of the county. Before you go in person, check the Tax Assessor-Collector website to find the office nearest you and confirm their hours, since some locations have limited schedules.

Online registration is available for renewals if your vehicle qualifies — typically vehicles with no liens, no address changes, and no title work needed. New registrations and transfers usually require in-person visits or mail submission with original documents.

Key Takeaways

  • The Bexar County Tax Assessor-Collector handles all vehicle registration, not a DMV office.
  • You need your vehicle title, proof of insurance, and a completed process form to register a new vehicle or transfer ownership.
  • Registration fees in Texas are based on vehicle weight and age, and Bexar County adds a local tax that varies by location within the county.
  • Your registration is valid for one or two years depending on your vehicle type, and renewal notices are mailed about 60 days before expiration.
  • If you buy a used vehicle from a private seller, you have 30 days to register it before you can legally drive it on public roads.

Documents you need for new registration

For a new registration in Bexar County, bring or mail the original vehicle title, a completed process for Texas Motor Vehicle Registration (Form VTR-130-U or VTR-130-T depending on whether you're registering a used or new vehicle). You also need proof of a current Texas vehicle inspection — this must be done at an authorized inspection station before you register.

Proof of insurance is required. Texas law mandates that all registered vehicles carry liability insurance. Bring your insurance card or a declaration page showing your policy number, coverage dates, and the vehicle identification number (VIN).

If you are registering a vehicle you just bought, bring the bill of sale or purchase agreement. If the title is held by a lienholder (like a bank or credit union), they must sign the title or provide a separate lien release document. If you are registering a vehicle with an out-of-state title, bring that title along with any documents showing you paid sales tax in the other state — Texas may credit that toward its registration tax.

Bring a photo ID and proof of your current address. A driver's license counts as both. If your address has changed since the title was issued, bring a utility bill or lease agreement showing your new address.

Registration fees and taxes in Bexar County

Texas registration fees are set by the state and based on your vehicle's weight. A passenger car typically costs between $50 and $60 for a one-year registration, but the exact amount depends on the vehicle's gross weight rating. Trucks and commercial vehicles cost more.

On top of the state fee, Bexar County adds a local vehicle tax. This tax rate varies depending on which precinct within the county you register in — it ranges from about 1.5% to 2.5% of the vehicle's value. The Tax Assessor-Collector's office will calculate this when you register; you cannot reduce it by registering in a different precinct if you live in Bexar County.

If your vehicle is older than 20 years, you may be able to register it as a classic or antique vehicle, which has lower fees. Ask the Tax Assessor-Collector whether your vehicle qualifies.

How long your registration lasts

Most passenger vehicles in Texas are registered for one year. Some vehicle types — including certain commercial vehicles and vehicles registered under a business — may be registered for two years. Your registration certificate will show your expiration date.

Your registration expires on the last day of the month shown on your certificate. You can renew up to 90 days before expiration. The Tax Assessor-Collector mails renewal notices about 60 days before your registration expires; if you do not receive one, you can still renew online or in person.

Driving with an expired registration is illegal in Texas. If you are stopped by law enforcement, you can face a fine. If your registration has been expired for more than a year, you will need to get a new vehicle inspection before you can renew.

Registering a vehicle you just bought

Texas law gives you 30 days from the date of purchase to register a vehicle. During those 30 days, you can drive it legally as long as you have proof of purchase and proof of insurance. After 30 days, you must have a valid registration or you cannot legally operate the vehicle on public roads.

If you bought the vehicle from a private seller, get the title signed over to you before you leave. The seller should sign the back of the title and print their name. You sign as the new owner. Do not accept a vehicle without a title in hand — if the seller says the title is "in the mail" or "at the bank," wait until you have it before you take possession.

If you bought from a dealer, they usually handle the paperwork and send it to the Tax Assessor-Collector on your behalf. Ask the dealer for a temporary registration document or receipt showing the date of sale. Keep this with you while you drive until your permanent registration arrives in the mail.

Renewing your registration online or by mail

If your vehicle has no liens, your address has not changed, and you have a current vehicle inspection, you can renew online through the Bexar County Tax Assessor-Collector website. You will need your registration number, VIN, and a valid payment method. Online renewal takes a few minutes, and your new registration is mailed to you within one to two weeks.

To renew by mail, fill out the renewal form that comes with your renewal notice and mail it with a check or money order to the Tax Assessor-Collector's office. Include your current registration certificate. Mail renewal takes longer — allow three to four weeks for processing and delivery.

If your vehicle has a lien, your address changed, or you need to update your name or other information on the registration, you must renew in person at a Tax Assessor-Collector office.

What to do if you lose your registration certificate

If your registration certificate is lost, stolen, or damaged, you can get a duplicate. Visit any Bexar County Tax Assessor-Collector office with your driver's license and VIN, or call their office to request a duplicate by mail. There is a small fee for a duplicate certificate, usually around $5 to $10.

You can drive legally while waiting for your duplicate as long as your registration has not expired. If you are stopped by law enforcement and cannot show your certificate, explain that you have requested a duplicate and provide your driver's license and proof of insurance.

Frequently Asked Questions

Can I register my vehicle online if I just moved to Bexar County?

No. Online renewal is only for vehicles already registered in Bexar County with no changes to your address or other information. If you moved from another county or state, you must register in person or by mail with your out-of-state title and proof of your new Bexar County address.

What if my vehicle title has a lien on it?

The lienholder's name will appear on the title. You can still register the vehicle, but the lienholder must sign the title or provide a separate authorization. If the lienholder is a bank or credit union, contact them to ask how they handle title signatures for registration. Some send a signed document directly to the Tax Assessor-Collector.

Do I need a vehicle inspection before I register?

Yes. Texas requires a current vehicle inspection before registration. The inspection must be done at an authorized inspection station and is valid for one year. The inspection checks your brakes, lights, emissions, and other safety items. Inspections typically cost $15 to $30.

How do I know which Bexar County Tax Assessor-Collector office to visit?

You can register at any office in Bexar County regardless of where you live. Check the Tax Assessor-Collector website for office locations, hours, and wait times. Some offices are busier than others, so calling ahead or checking online can help you find the shortest wait.

What happens if I drive with an expired registration?

Driving with expired registration is a traffic violation in Texas. You can be stopped and fined. If your registration has been expired for more than a year, you will need a new vehicle inspection before you can renew. Renew as soon as you notice your registration has expired.
