How to Find and Use the DMV Office in Katy, Texas

The Katy DMV is part of Harris County, not a separate office

Katy does not have its own dedicated DMV office. Instead, residents use the Harris County Tax Assessor-Collector's office, which handles vehicle registration, title work, and some driver license services for the Katy area. The closest full-service location is the Harris County office in Katy itself, located at 5602 Katy Mills Drive, Katy, TX 77494. This office handles vehicle registration renewals, title transfers, and vehicle inspections — the services most Katy residents need.

For driver license services like new licenses, renewals, or replacements, you may need to visit a Texas Department of Public Safety (DPS) Driver License office instead. Harris County has multiple DPS locations, and the one nearest to Katy depends on which part of town you live in. The Harris County Tax Assessor-Collector's office staff can tell you which DPS location serves your address.

What services the Katy Harris County office handles

The Harris County Tax Assessor-Collector's office in Katy processes vehicle registrations, including renewals, new registrations for vehicles you just bought, and registration transfers when you move to Texas. This office also handles title work — explore for a new title, transferring a title to a new owner, or correcting information on an existing title. Vehicle safety inspections (the annual inspection required to renew registration) can be done at this location as well.

The office does not issue or renew driver licenses. That work happens at a separate Texas DPS Driver License office. If you need a new driver license, a renewal, a replacement for a lost or damaged license, or a name change on your license, you must go to a DPS location, not the Tax Assessor-Collector's office.

How to find current hours and wait times

The Harris County Tax Assessor-Collector maintains a website with office hours, phone numbers, and real-time wait times for the Katy location. You can visit the Harris County Tax Assessor-Collector website and search for the Katy Mills Drive office to see how long the current wait is before you drive there. Hours vary by season and by day of the week, so checking online saves a wasted trip.

You can also call the Katy office directly at the phone number listed on the Harris County website. Staff can answer questions about what documents you need, whether your transaction can be done by mail, and whether you need an appointment. Some services do not require an appointment, but calling ahead can sometimes reduce your wait time.

Documents you typically need for vehicle registration and title work

For a vehicle registration renewal, bring your current registration card, proof of current auto insurance, and a valid photo ID. If your address has changed since your last registration, bring proof of your new address (a utility bill, lease, or mortgage statement dated within the last 60 days usually works).

For a title transfer — when you buy a used vehicle from a private seller — you need the signed title from the seller, a bill of sale, proof of insurance, and your ID. If the vehicle needs a safety inspection, you must have that completed before or at the same time you explore for the new title. The inspection can be done at the Harris County office or at any licensed inspection station in Texas.

For correcting information on a title or registration, bring the current document, your ID, and any paperwork that shows the correct information (such as a marriage certificate if your name changed). Requirements vary depending on what needs to be corrected, so call the office first to confirm what you need.

When to use mail or online services instead

Many vehicle registration and title transactions can be completed by mail or through the Harris County Tax Assessor-Collector's website without visiting the office in person. Registration renewals are often the easiest to handle remotely — you can renew online if your vehicle has a valid inspection and your insurance is current. Title transfers and new registrations for vehicles you just bought usually require an in-person visit or notarized documents sent by mail, so check the Harris County website to see which route works for your situation.

If you are renewing your registration and nothing has changed (same address, same vehicle, same insurance), the online renewal process takes about 10 minutes. You receive your new registration by mail within one to two weeks. This route avoids the office entirely and is faster than going in person.

Driver license services and where to find them

For driver license work, you need a Texas DPS Driver License office, not the Tax Assessor-Collector. The nearest DPS location to Katy depends on your address within Katy. The DPS website has a location finder where you can enter your zip code and see which office serves you. Some DPS offices are in other parts of Harris County, so the drive may be longer than the Tax Assessor-Collector's office in Katy.

DPS offices handle new driver licenses, renewals, replacements for lost or damaged licenses, name changes, and address changes on your license. You can also renew your driver license by mail or online in Texas if you meet certain requirements (your license must not be expired by more than two years, and you cannot have certain medical conditions). Check the DPS website to see whether you can renew without visiting an office.

Scams and safety information

Do not pay for vehicle registration or title services through any website or phone number you find by searching online. Scammers create fake Harris County or DPS websites that look official but steal your money and personal information. The real Harris County Tax Assessor-Collector website is harrisassessor.org. The real Texas DPS website is dps.texas.gov. Go directly to these sites or call the office phone number listed there — do not use a number from a search result.

Never send your original title, registration, or ID to anyone by mail unless you are certain you are mailing to the official Harris County office. Legitimate government offices do not ask you to mail original documents without first confirming the mailing address by phone. If someone calls you claiming to be from the DMV or Tax Assessor's office and asks for payment or personal information, hang up and call the office directly using the number on the Harris County website.

Be cautious of services that offer to "handle your registration for you" for a fee. These services are legal, but they charge significantly more than doing the work yourself. If you use one, verify that the company is licensed and check reviews before paying. Never give your login information or passwords to anyone, even if they claim to work for the government.

Frequently Asked Questions

Can I renew my vehicle registration online in Texas?

Yes, if your vehicle has a current safety inspection, your insurance is active, and your address has not changed. You can renew online through the Harris County Tax Assessor-Collector website. The new registration arrives by mail in one to two weeks. If anything has changed or your inspection is expired, you must renew in person or by mail with notarized documents.

What is the difference between the Tax Assessor-Collector and the DPS office?

The Tax Assessor-Collector handles vehicle registration, titles, and inspections. The DPS Driver License office handles driver licenses and driving-related documents. They are separate agencies with different locations and services. You may need to visit both depending on what you need.

Do I need an appointment at the Katy Harris County office?

Appointments are not always required, but wait times vary. Check the Harris County website for current wait times before you go, or call the office to ask whether an appointment would speed up your visit. Some services may have appointment availability while others operate on a first-come, first-served basis.

What if I just moved to Katy from another state?

You have 30 days to register your vehicle in Texas. Bring your out-of-state title or registration, proof of insurance, your ID, and proof of your new Katy address. The Harris County office will issue you a Texas title and registration. If your vehicle needs a safety inspection, that must be completed before or at the same time you register.

Can I transfer my vehicle title if the seller is not present?

No. The seller must sign the title in front of a notary public or at the Harris County office. If the seller lives out of state or cannot visit in person, they can have the title notarized and mail it to you, then you can complete the transfer at the Harris County office with the notarized title and your ID.
