Book your Houston DMV appointment online or by phone before you visit
The Harris County Tax Assessor-Collector's Office (which handles vehicle registration and title work in Houston) requires you to schedule an appointment in advance. You cannot walk in without one. You can book through the online appointment system at hctax.net, or call the office directly at 713-274-8000 during business hours.
The appointment system shows you available dates and times at the location nearest you. Most appointments are available within one to three weeks, though this varies by season and which service you need. You will receive a confirmation number by email or text when you book.
Bring that confirmation number with you on the day of your appointment, along with all required documents for your specific transaction — whether that is a title transfer, registration renewal, or address change.

How to use the online appointment system
Go to hctax.net and look for the appointment scheduling link on the homepage. You will be asked to select the service you need — for example, vehicle registration, title transfer, or registration renewal. The system will then show you available dates and times at different office locations across Harris County.
Choose the location and time that works for you. You will need to enter your name, phone number, and email address. The system will send you a confirmation with your appointment number, date, time, and location. Save this confirmation or write down your appointment number.
If you cannot find the appointment link or prefer to book by phone, call 713-274-8000. Staff can schedule you over the phone and will give you a confirmation number at that time.
What documents to bring to your appointment
The documents you need depend on what you are doing. For a vehicle registration renewal, bring your current registration card, proof of insurance, and a valid ID. For a title transfer, bring the signed title from the previous owner, proof of insurance, your ID, and proof of residency (such as a utility bill or lease).
If you are registering a vehicle for the first time in Texas, bring the manufacturer's certificate of origin (or the title from another state), proof of insurance, your ID, and proof of residency. If you are changing your address on an existing registration, bring your current registration card and a valid ID.
The office website at hctax.net lists the full document requirements for each service. Check the specific page for what you need before your appointment so you do not have to reschedule.
Office locations and hours in the Houston area
The Harris County Tax Assessor-Collector's Office has multiple locations throughout the county. The main office is downtown Houston, but there are satellite offices in areas like Spring, Katy, Pearland, and The Woodlands. When you book your appointment online, you can see which locations have availability and choose the one closest to you.
Most offices are open Monday through Friday, 8 a.m. to 5 p.m., though some locations have different hours. Check hctax.net or call 713-274-8000 to confirm the hours at your chosen location before you go.
If you cannot make your appointment, you can reschedule through the online system or by calling the office. There is no penalty for rescheduling as long as you do it before your appointment time.
What to expect when you arrive
Arrive 10 to 15 minutes early. Bring your confirmation number and all required documents. Check in at the front desk and give them your confirmation number. You will be called when it is your turn, usually within 15 to 30 minutes of your appointment time.
The staff member will review your documents, answer any questions, and process your transaction. Most vehicle registration and title work takes 15 to 30 minutes once you are called. You will receive a receipt and any new documents (such as a registration card or title) before you leave.
If the office discovers that you are missing a document, they may ask you to reschedule rather than process your transaction that day. This is why checking the document list beforehand is important.
If you need to cancel or reschedule
You can cancel or reschedule your appointment through the online system at hctax.net or by calling 713-274-8000. If you reschedule online, the system will show you new available times and locations. If you call, staff will help you find a new appointment time.
There is no charge for rescheduling or canceling. If you miss your appointment without canceling, you will need to book a new one to be seen.
Frequently Asked Questions
Can I get an appointment the same day or next day?
Same-day appointments are rarely available. Most appointments are scheduled one to three weeks out, depending on the season and location. If you have an urgent need, call 713-274-8000 to ask if any locations have sooner openings.
What if I do not have an email address to receive my confirmation?
Call 713-274-8000 to book by phone instead. Staff will give you a confirmation number verbally and can text or mail your confirmation if you prefer.
Do I need to bring original documents or can I bring copies?
The office requires original documents or certified copies for most transactions. Check hctax.net for your specific service to see which documents must be originals and which can be copies.
What if I arrive late to my appointment?
Call the office as soon as you know you will be late. They may be able to work you in, but arriving significantly late may result in your appointment being canceled and you having to reschedule.
Is there a fee to schedule an appointment?
No. Scheduling the appointment is free. You will pay fees only for the actual service — such as registration renewal or title transfer — when you complete your transaction at the office.
