Where to register your vehicle in Hays County
Vehicle registration in Hays County is handled by the county tax assessor-collector's office, not by a separate motor vehicle department. You'll register your vehicle at the Hays County Tax Assessor-Collector office, located in San Marcos, or at one of their satellite locations if you live in a different part of the county. The main office is at 111 W. Hopkins Street, San Marcos, TX 78666.
Hays County also operates satellite offices in Kyle and Dripping Springs to serve residents in those areas. Each location handles the same registration services, so you can visit whichever is most convenient. Hours vary by location, so check the county website or call ahead before you go.
You can also renew your registration by mail or online through the Texas Department of Motor Vehicles (DMV) website if you're renewing a vehicle that's already registered in Texas and meets certain conditions. However, new registrations and title transfers must be done in person at the tax assessor-collector's office.

Documents you'll need to bring
For a new registration, bring your vehicle's title (the document proving ownership), proof of insurance from a Texas-based insurer, and a valid photo ID such as a driver's license or passport. If you're registering a vehicle you just bought, you'll also need the bill of sale or purchase agreement showing the sale date and price.
If you're transferring a title from another state, bring the out-of-state title, the bill of sale, and proof of a passing vehicle inspection performed by a licensed Texas inspector. Texas requires an inspection before you can register an out-of-state vehicle, and the inspection must be done after you own the vehicle but before you register it.
For renewals by mail or online, you typically need only your renewal notice (which the county mails to you) and a payment method. If you're renewing in person, bring your current registration card and proof of insurance.
Registration fees and what they cover
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, while heavier vehicles cost more. Hays County adds a local fee on top of the state fee; the exact amount varies, so ask at the office or check the county website for the current rate.
Your registration fee covers your license plate (if you're registering for the first time), the registration certificate, and the registration sticker that goes on your license plate. If you're renewing, you pay only the registration fee unless you need a replacement plate.
If you register a vehicle partway through the year, you may be charged a prorated fee. The county can explain how this works for your specific situation when you visit or call.
How long registration takes and when it expires
If you register in person at the tax assessor-collector's office, you'll receive your registration sticker and certificate the same day. You can drive home with your new registration when ready. If you mail in a renewal, allow two to three weeks for processing.
Your registration is valid for one year or two years depending on your vehicle type. Passenger vehicles are typically registered for one year, while some commercial or specialty vehicles may be registered for two years. Your registration certificate will show the expiration date.
The county will mail you a renewal notice about 60 days before your registration expires. If you don't receive one, you can check your expiration date on the Texas DMV website or by calling the tax assessor-collector's office.
Registering a vehicle you bought from a private seller
When you buy a vehicle from a private seller in Texas, the seller must sign the title over to you and provide you with a bill of sale. You then have 30 days to register the vehicle in your name. If you don't register within 30 days, you may face a late fee.
Bring the signed title, the bill of sale, proof of insurance, and your ID to the tax assessor-collector's office. The office will process the title transfer and issue your new registration at the same time. The title transfer fee is separate from the registration fee; ask the office for the current amount.
If the title has a lien on it (meaning a lender still owns part of the vehicle), the lender's name will appear on the title. You can still register the vehicle, but the lender remains listed on the registration until the loan is paid off.
Registering a vehicle you bought from a dealership
When you buy from a dealership, the dealer typically handles the title transfer paperwork and gives you temporary registration documents. You'll receive a temporary registration permit that's valid for 30 to 60 days while the permanent registration is being processed. The dealer will tell you when to expect your permanent registration in the mail.
If you don't receive your permanent registration within the timeframe the dealer gave you, contact the tax assessor-collector's office with your temporary permit number. They can look up the status of your process.
Some dealerships offer to handle registration for you as part of the purchase, which means they'll submit your paperwork to the tax assessor-collector's office on your behalf. If the dealer does this, confirm that you've received your permanent registration before the temporary permit expires.
Renewing your registration by mail or online
If your vehicle is already registered in Texas and you're renewing (not transferring or registering for the first time), you can renew by mail or online through the Texas DMV website. To renew online, go to the DMV's vehicle registration renewal page, enter your vehicle information and renewal notice number, and pay the fee with a credit or debit card.
To renew by mail, fill out the renewal notice the county sends you, include a check or money order for the fee, and mail it back to the address on the notice. Mail renewals take longer than online renewals, so submit yours at least three weeks before your registration expires.
You cannot renew online or by mail if your vehicle failed inspection, if your insurance has lapsed, or if you have unpaid traffic violations or registration fees. In those cases, you'll need to visit the tax assessor-collector's office in person.
Frequently Asked Questions
What if I move to a different county in Texas?
You don't need to re-register your vehicle when you move within Texas. Your registration remains valid until the expiration date on your certificate, regardless of where you live. When you renew, you can renew through any county's tax assessor-collector office or online through the state DMV.
Can I register a vehicle if I don't have a Texas driver's license?
Yes. You need a valid photo ID (such as a passport or out-of-state driver's license) and proof of residency in Texas, such as a utility bill or lease agreement. The tax assessor-collector's office can tell you which documents count as proof of residency.
What happens if my registration expires?
Driving with an expired registration is a traffic violation in Texas. You can be stopped and cited. Renew your registration before the expiration date shown on your certificate. If your registration has already expired, you can still renew it, but you may owe a late fee in addition to the renewal fee.
Do I need to register a vehicle I'm only keeping temporarily?
If you own the vehicle, even temporarily, you must register it in Texas within 30 days of purchase. If you're borrowing a vehicle, you don't need to register it, but the owner must have a valid registration. If you're leasing a vehicle, the leasing company handles registration.
Where do I get a vehicle inspection in Hays County?
Vehicle inspections are performed by licensed private inspection stations throughout Hays County, not by the tax assessor-collector's office. You can find inspection stations by searching online or asking at a local auto repair shop. The inspection costs around $25 to $30 and is valid for one year from the inspection date.
