Where to register your vehicle in Hays County
In Hays County, you register your vehicle through the Hays County Tax Assessor-Collector's office, not through a separate DMV. The Tax Assessor-Collector handles both vehicle registration and the collection of property taxes for the county. You can register in person at their main office in San Marcos or at one of their satellite locations in Kyle, Dripping Springs, or Wimberley.
The office is located at 111 E. San Antonio Street, San Marcos, TX 78666. You can call them at (512) 393-7675 to confirm hours, ask about wait times, or get directions to a satellite office closer to you. Online registration is not available through Hays County, so you must visit in person or use mail-in registration if you meet the requirements.

Documents you need to bring
Bring your vehicle's title or proof of ownership — this is the most important document. If you bought the vehicle recently, bring the bill of sale or purchase agreement. If the title is held by a lender, bring proof from the lender that you own the vehicle or a letter authorizing registration.
You also need proof of insurance that meets Texas minimum requirements (liability coverage). Bring the actual insurance card or a printed declaration page from your insurer showing your policy number and coverage dates. The policy must be active on the day you register.
Bring a valid photo ID — a driver's license, passport, or state ID card. You will also need proof of residency in Hays County, such as a utility bill, lease agreement, mortgage statement, or bank statement dated within the last 60 days and showing your current address.
If you are registering a vehicle with an out-of-state title, bring the out-of-state title or registration document. If the vehicle is new and you have a manufacturer's certificate of origin instead of a title, bring that document.
Registration fees and how they are calculated
Texas registration fees are set by the state and are based on the vehicle's declared value, not the price you paid. The Tax Assessor-Collector uses a state formula to determine value based on the vehicle's year, make, model, and condition. Fees typically range from around $50 to $300 for standard passenger vehicles, but can be higher for trucks, commercial vehicles, or vehicles with high declared values.
You will also pay a county fee that goes to Hays County. This fee is separate from the state registration fee and is set by the county commissioners. The total cost is the state fee plus the county fee plus any applicable local option fees.
If you are registering a vehicle for the first time in Texas (moving from another state), you may owe a one-time title transfer fee in addition to registration. Ask the Tax Assessor-Collector's office for an estimate before you visit, or call (512) 393-7675 to ask about the likely cost for your vehicle type.
How long registration takes and when it is valid
Registration is typically processed the same day you visit the office, though wait times vary by location and time of day. You will receive your registration sticker (also called a validation sticker) and registration card on the spot. The sticker goes on your license plate, and the card stays in your vehicle.
Your registration is valid for one or two years, depending on what you choose at the time of registration. Two-year registration costs more upfront but means you renew less often. One-year registration is cheaper but requires you to renew annually. Your registration expires on the last day of the month shown on your sticker.
You must display the registration sticker on your license plate at all times. If your sticker is missing, damaged, or illegible, you can get a replacement from the Tax Assessor-Collector's office for a small fee.
Renewing your registration by mail
If your vehicle information has not changed since your last registration (same owner, same address, same vehicle), you may renew by mail without visiting the office. You will receive a renewal notice in the mail about 60 days before your registration expires.
To renew by mail, send the renewal notice, your current registration card, proof of insurance, and a check or money order for the renewal fee to the address shown on the notice. Do not send cash. Mail your renewal at least two weeks before your registration expires to allow time for processing.
If you have moved, changed your vehicle, or your insurance has lapsed, you cannot renew by mail and must visit the office in person. The Tax Assessor-Collector's office will contact you if your renewal cannot be processed by mail.
Registering a vehicle with an out-of-state title
If you are moving to Hays County from another state with a vehicle registered out of state, you have 30 days from the date you establish residency in Texas to register the vehicle in Hays County. Bring your out-of-state title or registration, proof of insurance, proof of residency in Hays County, and a valid ID.
The Tax Assessor-Collector will process a title transfer and issue a Texas title and registration. You will pay both the state registration fee and a title transfer fee. The title transfer fee varies but is typically $20 to $30. Processing usually takes the same day, though the actual title may arrive by mail within two to four weeks.
If your out-of-state vehicle has a lien (the lender holds the title), bring proof from the lender that you own the vehicle or a letter authorizing the transfer. Some lenders will mail the title directly to the Tax Assessor-Collector's office if you ask them to.
What to do if your registration is lost or damaged
If your registration sticker is missing, faded, or damaged, visit the Tax Assessor-Collector's office with your current registration card and a valid ID. You can get a replacement sticker for a small fee, usually around $5 to $10. Replacement stickers are issued the same day.
If you lose your registration card (the paper document), you can request a duplicate from the office. Bring your vehicle title or current registration sticker and a valid ID. A duplicate card costs a small fee and is issued the same day.
If your license plate is damaged or missing, you will need to visit the office to get a new plate. This is a separate process from registration renewal and may cost more than a registration sticker replacement. Call the office first to ask what documents to bring.
Frequently Asked Questions
Can I register a vehicle if I do not have a Texas driver's license yet?
Yes. You need a valid photo ID (passport, state ID, or out-of-state driver's license), proof of insurance, proof of residency in Hays County, and your vehicle title. You do not need a Texas driver's license to register a vehicle, though you will need one to drive it legally on public roads.
What if my vehicle title has a lien on it?
You can still register the vehicle. Bring proof from the lender that you own the vehicle or a letter authorizing registration. Some lenders will send the title directly to the Tax Assessor-Collector's office if you request it. Call your lender to ask whether they can do this before you visit the office.
Do I need an inspection before I register?
Texas does not require a vehicle inspection for registration. However, you do need proof of insurance that meets state minimum requirements. If your vehicle is older or has been out of service, some insurers may require an inspection before they will insure it, but that is between you and your insurance company, not the Tax Assessor-Collector.
What happens if I register late?
Driving with an expired registration is a traffic violation in Texas. You can be stopped and cited. If your registration has expired, renew it as soon as possible. The Tax Assessor-Collector's office will not charge a late fee for renewing after the expiration date, but you are not legally allowed to drive until you renew.
Can I register a vehicle that I am buying from a private seller?
Yes. Bring the title signed by the seller, a bill of sale or purchase agreement, proof of insurance, proof of residency, and a valid ID. The title must be signed and dated by the seller. If the seller's name is misspelled or the title is damaged, contact the Tax Assessor-Collector's office before you visit to ask what additional documents you may need.
