What the Katy DMV Office Handles

The Katy area is served by the Harris County Tax Assessor-Collector's office, which handles driver's license renewals, replacements, and address changes, along with vehicle registration and title work. This is not a standalone DMV building — it is part of Harris County's system. You cannot renew your license or register a vehicle at a city hall or police station in Katy; you must go to a Harris County office or use their online options.

Katy itself does not have its own dedicated tax assessor-collector location. The nearest offices are in west Houston and surrounding areas. Before you drive to an office, check which location is closest to you and whether it handles the specific transaction you need — some offices have limited services.

Texas allows you to handle many transactions online or by mail, which often saves a trip. Knowing which route works for your situation will tell you whether you need to visit an office at all.

Driver's License Renewals and Replacements

If your Texas driver's license is expiring or you need a replacement, you have three paths: online through the Texas Department of Public Safety (DPS) website, by mail, or in person at a Harris County office. Online renewal is the fastest and most convenient if you are may be able to access. You can renew online if your license is not expired, you have no medical conditions that require a vision test, and you have not had certain violations or suspensions in the past five years.

To renew online, go to the Texas DPS website, log in with your driver's license number and date of birth, and follow the prompts. You will pay the renewal fee by credit or debit card. Your new license will arrive by mail in about two weeks. If you do not meet the online requirements, you must renew by mail or in person.

For a replacement license — if yours was lost, stolen, or damaged — you must visit a Harris County office or submit an process by mail. Bring your current license if you have it, proof of your Social Security number (Social Security card, W-2, or 1099), and proof of residency (utility bill, lease, or bank statement dated within the last 60 days). If your license was stolen, bring a police report or affidavit.

Vehicle Registration and Title Transactions

Vehicle registration renewal, new registration, and title transfers all go through the Harris County Tax Assessor-Collector. You can renew your vehicle registration online through the Texas DPS website if your vehicle is registered in Texas, your registration is not expired, and you have no outstanding violations or liens. Online renewal takes about two weeks and costs the standard registration fee.

If you cannot renew online, you can renew by mail or in person. To renew by mail, submit your current registration card, proof of insurance, and payment to the Harris County office. For new registration or title work — buying a used vehicle, transferring a title, or registering a vehicle for the first time — you must visit an office in person or use the mail-in process, which takes longer.

Bring your vehicle's title or bill of sale, proof of insurance, proof of residency, and a completed process form (available on the Harris County website). If the vehicle has a lien, bring the lienholder's information. Title transfers typically take one to two weeks by mail and same-day or next-day in person, depending on the office's workload.

Address Changes and License Updates

If you moved to a new address in Katy or elsewhere in Texas, you must update your driver's license within 30 days. You can do this online through the Texas DPS website if your license is not expired and you have no medical restrictions. The online process takes about 10 minutes, costs a small fee, and your updated license arrives by mail.

If you cannot update online, visit a Harris County office with your current license and proof of your new address (utility bill, lease, or bank statement). Address changes are processed quickly in person, often the same day. Your new license will be mailed to your updated address.

Vehicle registration address changes must also be updated. If you registered your vehicle in another county or state and moved to Katy, you will need to re-register it in Harris County. Bring your current registration, proof of insurance, proof of residency in Katy, and your vehicle's title or bill of sale.

Finding the Right Harris County Office and Hours

Harris County operates multiple tax assessor-collector offices throughout the county. The offices closest to Katy are typically in west Houston and surrounding areas. Each office handles driver's licenses, vehicle registration, and title work, but some have limited hours or services. Before you visit, check the Harris County Tax Assessor-Collector website to find the office nearest you, confirm it is open, and see whether it offers the specific service you need.

Most offices are open Monday through Friday during standard business hours, with some Saturday hours at select locations. Wait times vary by location and time of day — early morning and mid-week visits are usually faster than afternoons or Fridays. Some offices allow you to reserve a time slot online, which can save you from waiting in line.

If you are unable to visit an office, the Harris County website lists which transactions can be handled by mail. Mail-in processing takes longer — typically one to three weeks — but eliminates the need to travel.

What Documents You Need to Bring

The documents required depend on your transaction. For a driver's license renewal or replacement, bring your current license (if you have it), proof of your Social Security number, and proof of residency. Proof of residency can be a utility bill, lease agreement, bank statement, or government mail dated within the last 60 days.

For vehicle registration or title work, bring your vehicle's title or bill of sale, proof of insurance, proof of residency, and a completed process form. If the vehicle has a lien, bring the lienholder's name and address. If you are transferring a title from another state, bring the out-of-state title and any documents showing the transfer of ownership.

For an address change, bring your current license and proof of your new address. If you are updating vehicle registration, bring your current registration card and proof of your new address. Having all required documents before you visit or mail your process will prevent delays and rejected submissions.

Online and Mail-In Options to Avoid a Trip

Texas and Harris County offer several transactions online or by mail, which can save you a trip to an office. Driver's license renewals, address changes, and vehicle registration renewals can often be completed online through the Texas DPS website. The process is straightforward, fees are paid by card, and documents arrive by mail within two weeks.

If you prefer to mail documents, read the process forms from the Harris County Tax Assessor-Collector website, fill them out, and mail them with your documents and payment to the office address listed on the form. Include a self-addressed, stamped envelope if you want your documents returned. Mail-in processing takes one to three weeks, depending on the transaction.

Not all transactions can be done online or by mail — title transfers, new vehicle registration, and certain license replacements require an in-person visit. Check the Harris County website or call the office to confirm whether your specific transaction can be handled remotely before you plan a visit.
