Where to Register Your Vehicle in Hays County
Vehicle registration in Hays County is handled by the Hays County Tax Assessor-Collector's Office, which processes all new registrations, renewals, and title transfers for the county. You can register at the main office in San Marcos or at one of the satellite locations in Wimberley or Dripping Springs, depending on which is most convenient. The Tax Assessor-Collector's Office is the only local body that issues registration stickers and processes the paperwork required by Texas law.
Registration is not optional — Texas law requires every vehicle driven on public roads to display a current registration sticker on the rear license plate. The sticker shows the month and year your registration expires. If you drive without one, you can be cited and fined.

Documents You Need to Bring
To register a vehicle for the first time in Hays County, bring your vehicle title (the document proving ownership), proof of a current Texas auto insurance policy, and a completed process for Motor Vehicle Registration. The form is available at the Tax Assessor-Collector's Office or on the Texas Department of Motor Vehicles website. You will also need to bring a photo ID and proof of your current address — a utility bill, lease, or mortgage statement dated within the last 60 days works.
If you are registering a vehicle you recently purchased, the title should be in your name. If the title is still in the seller's name, you will need to complete a transfer of ownership first. The Tax Assessor-Collector's Office can tell you whether your title is ready to register or if additional steps are needed.
For renewals, you can often skip the office entirely. If your registration is current and your address has not changed, you can renew online through the Texas Department of Motor Vehicles website or by mail. You will receive a renewal notice in the mail before your sticker expires.
Registration Fees and What They Cover
Texas sets registration fees based on your vehicle's weight, not its age or value. A passenger car typically costs between $50 and $60 per year, while heavier vehicles cost more. Trucks and SUVs may fall into a higher weight category. The exact fee depends on your vehicle's specifications, which the Tax Assessor-Collector's Office will calculate when you register.
Your registration fee covers the sticker you place on your license plate and the registration record kept by the state. It does not cover your license plate itself — if you need a new plate, that is a separate transaction. The office also collects a small county fee on top of the state registration fee; this amount varies slightly but is typically under $10.
If you register a vehicle partway through the year, you still pay the full annual fee. Texas does not prorate registration costs based on when you register during the year.
The Registration Process Step by Step
If you are registering in person, arrive with all required documents and expect to spend 15 to 30 minutes at the office, depending on how busy it is. The staff will review your title and insurance proof, have you sign the process form, calculate your fee, and issue your registration sticker on the spot. You can place the sticker on your license plate when ready.
If you are renewing by mail, send your renewal notice, proof of insurance, and a check to the address listed on the notice. Processing by mail typically takes one to two weeks. Your new sticker will arrive by mail, and you should place it on your plate before your current registration expires.
If you are renewing online through the Texas Department of Motor Vehicles website, you will need your driver's license number, vehicle identification number (VIN), and current registration number. Online renewal is usually the fastest option and takes only a few minutes. You can print a temporary registration while you wait for your sticker to arrive by mail.

Special Situations: New Residents and Out-of-State Vehicles
If you are moving to Hays County from another Texas county, you have 30 days to register your vehicle at the new location. Your current registration remains valid during this period, so there is no rush, but registering within the window keeps you in compliance with state law. Bring your current registration, title, proof of insurance, and proof of your new Hays County address.
If you are moving to Hays County from out of state, you have 30 days from the date you establish residency to register your vehicle with Texas plates. Out-of-state plates are not valid in Texas after this period. You will need your out-of-state title, proof of insurance, and a completed process for Motor Vehicle Registration. The Tax Assessor-Collector's Office will process your title transfer and issue your Texas registration at the same time.
If your vehicle is financed, the lender's name may appear on the title. This does not prevent you from registering — bring the title as it is, and the office will process it. The lender does not need to sign off on registration.
Frequently Asked Questions
What if my registration sticker is damaged or missing?
You can request a replacement sticker from the Tax Assessor-Collector's Office. Bring your current registration and proof of insurance. There is usually a small replacement fee, typically $5 to $10. You can also request a replacement by mail if you prefer.
Can I register my vehicle online instead of going to the office?
You can renew an existing registration online through the Texas Department of Motor Vehicles website. For a first-time registration or a title transfer, you must visit the Tax Assessor-Collector's Office in person or by mail. Some counties offer online registration for new vehicles, but Hays County requires an in-person visit for new registrations.
What happens if my registration expires?
Driving with an expired registration sticker is a traffic violation. You can be stopped and cited. Renew before the expiration date shown on your current sticker. If your registration has already expired, renew when ready — the Tax Assessor-Collector's Office will issue a new sticker without penalty, though you may owe a late fee depending on how long it has been expired.
Do I need to register my vehicle if I only drive it occasionally?
Yes. Any vehicle driven on public roads in Texas must be registered, regardless of how often you drive it. If you do not plan to drive a vehicle, you can request a non-operation designation from the Tax Assessor-Collector's Office, which suspends your registration and may reduce your fees, but the vehicle still cannot be driven on public roads.
How do I transfer my registration if I sell my vehicle?
You do not transfer a registration — the new owner registers the vehicle in their name. As the seller, you should notify the Tax Assessor-Collector's Office that you have sold the vehicle so your registration is cancelled. The buyer will then bring the title and proof of insurance to register it themselves.
