Where to register your vehicle in Travis County

In Travis County, you register your vehicle through the Travis County Tax Assessor-Collector's Office, not through a separate DMV or motor vehicle department. The Tax Assessor-Collector handles both vehicle registration and the property tax assessments the county uses to fund schools and local services. You can register in person at one of their offices, by mail, or online through their website.

The main office is located in downtown Austin at 5500 Burnet Road, but the county operates several satellite locations in areas like Cedar Park, Pflugerville, and Lakeway. Each location handles the same registration services, so you can visit whichever is most convenient. Hours vary by location but typically run Monday through Friday, 8 a.m. to 5 p.m., with some offices open Saturday mornings.

If you prefer not to visit in person, the Tax Assessor-Collector's online portal lets you renew existing registrations without leaving home. New registrations and transfers of ownership usually require an in-person visit or notarized documents sent by mail, because staff need to verify your vehicle's title and inspect certain documents.

Key Takeaways

  • Travis County's Tax Assessor-Collector handles all vehicle registration, not a separate motor vehicle office.
  • You can renew an existing registration online, but new registrations and ownership transfers typically require an in-person visit or mailed documents with notarization.
  • The county operates multiple office locations throughout the Austin area, all with the same services and similar hours.
  • You will need your vehicle's title, proof of insurance, and a valid ID to complete registration in person.
  • Registration fees in Travis County depend on your vehicle's age and weight, and the county charges an additional local option tax on top of the state fee.

Documents you need to bring

For a new vehicle registration, bring your vehicle's title (the official ownership document from the previous owner or the dealership), a valid photo ID, and proof of liability insurance. Texas law requires all registered vehicles to carry insurance, and the Tax Assessor-Collector will ask to see your policy or declaration page showing your vehicle's VIN and coverage dates.

If you are registering a vehicle you just bought from a private seller, bring the title signed by the previous owner and your bill of sale. If the title is held by a lender (because you financed the vehicle), the lender will send the title to you after you pay off the loan, or you may need to bring a lien release document showing the lender has released their claim.

For renewals, you typically only need your renewal notice (which the county mails to you before expiration) and proof of current insurance. If you are renewing online, you will enter this information into the portal instead of bringing physical documents.

Registration fees and what they cover

Travis County registration fees are not flat rates—they depend on your vehicle's gross vehicle weight rating (GVWR), which is the maximum weight the vehicle is designed to carry, and the vehicle's age. A standard passenger car typically costs less than a truck or SUV with a higher GVWR. The state of Texas sets a base fee, and Travis County adds a local option tax on top of that amount.

The exact fee you owe depends on whether you are registering for a full year, a partial year, or renewing an existing registration. The Tax Assessor-Collector's website has a fee calculator where you can enter your vehicle's details and see the exact amount before you visit or pay online. Fees are generally due at the time of registration, and you can pay by cash, check, card, or electronic transfer depending on which method you use to register.

Your registration covers your license plate and registration sticker (the decal you place on your plate), which are valid for one year from the month of registration. If you register in March, your registration expires in March of the following year. You will receive a renewal notice in the mail about 30 days before expiration.

How to register online versus in person

The Tax Assessor-Collector's online system works best for renewals of vehicles already registered in Travis County. You log in with your vehicle's license plate number and the last four digits of your VIN, review the fee, and pay by card. The process takes about 10 minutes, and you receive a temporary registration number by email when ready. Your physical sticker arrives by mail within one to two weeks.

New registrations and transfers of ownership require more verification and cannot be completed entirely online. You must visit an office in person or mail in your documents with a notarized signature. If you mail documents, include your completed process form (available on the Tax Assessor-Collector's website), your title, proof of insurance, and a check or money order for the fee. Mail to the main office address and allow two to three weeks for processing.

In-person registration at an office is usually the fastest route for new vehicles. Staff can verify your documents on the spot, answer questions about fees, and issue your temporary registration when ready. You walk out with a registration number you can use right away, and your sticker arrives by mail within two weeks.

What happens if your registration expires

Driving with an expired registration in Texas is a traffic violation. A police officer can stop you and issue a citation, which carries a fine. If your registration has been expired for more than a few days, you cannot legally drive the vehicle on public roads, even to go to the Tax Assessor-Collector's office to renew it.

If your registration is about to expire, renew it before the expiration date. The Tax Assessor-Collector mails renewal notices about 30 days in advance, so check your mail regularly. If you miss the notice or lose it, you can still renew online using your license plate number and VIN, or visit an office and bring your expired registration sticker or plate.

If your registration has already expired, you can still renew it at any Tax Assessor-Collector office. You will owe the renewal fee plus any applicable late fees, which vary depending on how long the registration has been expired. The county may also charge a reinstatement fee if the registration has been expired for several months.

Transferring ownership or changing vehicle information

If you buy a vehicle from someone else in Travis County, you need to transfer the title into your name. This is different from registration—the title proves ownership, while registration allows you to legally drive the vehicle. Bring the signed title, your ID, proof of insurance, and the bill of sale to a Tax Assessor-Collector office. Staff will process the title transfer and issue a new registration in your name.

If you move to a different address within Travis County, you can update your registration address online or by visiting an office. Bring your current registration and a piece of mail showing your new address. If you move out of Travis County to another Texas county, you will need to register with that county's tax assessor-collector instead.

If your vehicle's information changes—for example, you repaint it a different color or modify the engine—you may need to update your registration. Contact the Tax Assessor-Collector's office to ask whether the change requires a new registration or just a notation in their system.

Frequently Asked Questions

Can I register a vehicle online if I just bought it from a dealer?

No. New registrations require an in-person visit or mailed documents with notarization so staff can verify your title and ownership. Once your vehicle is registered in Travis County, you can renew online in future years.

What if I lose my registration sticker or license plate?

Visit a Tax Assessor-Collector office with your ID and proof of insurance. Staff can issue a replacement sticker or plate for a fee. If your plate was stolen, bring a police report. You can also request a replacement by mail if you mail in a completed form and payment.

Do I need to register my vehicle if I just moved to Travis County from out of state?

Yes. Texas requires all vehicles driven on public roads to be registered in the state. Bring your out-of-state title, your ID, proof of insurance, and a bill of sale (if you bought it from a private seller) to a Tax Assessor-Collector office. Staff will issue a Texas title and registration.

How long does registration take if I mail in my documents?

Processing typically takes two to three weeks from the date the office receives your envelope. Mail your documents to the main office address on the Tax Assessor-Collector's website, and include a check or money order for the fee. Consider mailing at least three weeks before you need to drive the vehicle.

What if my vehicle's title is held by a lender?

The lender's name appears on the title as the lienholder. You can still register the vehicle, but the lender must sign off on the title transfer when you sell it or pay off the loan. Once you pay off the loan, the lender will send you a lien release document, which you bring to the Tax Assessor-Collector to update your registration.
