What you need to register a car in Texas

Texas car registration is handled by your county tax assessor-collector's office, not a state DMV — Texas does not have a DMV. You will need to visit in person or mail documents to your county office. The basic requirements are proof of ownership (your title or bill of sale), proof of identity, proof of residency in Texas, and payment of the registration fee.

The registration fee depends on your vehicle's weight and age. Newer vehicles and heavier vehicles cost more. You can find your vehicle's weight on the door jamb or in your owner's manual. Texas also charges a one-time title transfer fee when you first register a vehicle in the state, separate from the annual registration fee.

If you are registering a vehicle you just bought from a private seller, you will also need a passing emissions test (in most Texas counties) and proof that you have liability insurance. The insurance company can provide a document showing your policy is active.

Where to register and what documents to bring

Find your county tax assessor-collector by searching "[county name] tax assessor-collector" plus your county name. Most offices are open Monday through Friday during business hours, though some offer limited Saturday hours. Call ahead to confirm hours and whether you need an appointment, as some offices now require them.

Bring your title (if you have one), bill of sale (if buying from a private seller), photo ID, and proof of Texas residency. Proof of residency can be a utility bill, lease, mortgage statement, or government mail with your name and address. Bring the original documents or certified copies — photocopies alone are usually not accepted.

You will also need proof of liability insurance. Call your insurance company or log into your account to print a declarations page or proof of insurance letter. This document must show your name, vehicle identification number (VIN), and that coverage is active.

Emissions testing and when you need it

Most Texas counties require a passing emissions test before you can register a vehicle. The test checks that your vehicle's pollution controls are working. You take your car to a licensed emissions testing station (not the tax assessor's office) and pay a fee, usually between $15 and $30 depending on your vehicle type.

Some rural Texas counties are exempt from emissions testing. You can check whether your county requires it by searching "Texas emissions testing [your county name]" or calling your county tax assessor-collector. If your county requires it, you must pass the test before you register.

Bring your vehicle registration paperwork or VIN to the testing station. The test takes about 15 minutes. If you pass, you receive a certificate that you bring to the tax assessor's office. If you fail, you have time to repair the vehicle and retest before your registration important date.

Registration fees and how they are calculated

Texas registration fees are based on your vehicle's weight and how old it is. A new vehicle weighing 3,500 pounds costs more than a 10-year-old vehicle of the same weight. The Texas Department of Motor Vehicles publishes a fee schedule online where you can enter your vehicle's weight and model year to see the exact amount you will owe.

When you register a vehicle in Texas for the first time, you also pay a one-time title transfer fee. This fee is separate from the annual registration fee. If you are renewing a registration you already have in Texas, you pay only the annual registration fee, not the title fee again.

Some vehicles may have access to for reduced fees. Vehicles over 20 years old, electric vehicles, and certain other categories may have lower rates. Ask your tax assessor-collector whether your vehicle qualifies for a reduced fee.

How to register by mail or online

Some Texas counties allow you to renew your registration by mail or online if your vehicle has not changed and you do not need a new title. Check your county tax assessor-collector's website to see whether mail or online renewal is available in your county.

To renew by mail, send your current registration card, payment, and any required documents to your county office. Include a return envelope with postage. Processing takes two to four weeks by mail, so send your renewal at least six weeks before your registration expires.

Online renewal is faster if your county offers it. You log in with your driver's license number and vehicle identification number, pay the fee by credit or debit card, and receive your new registration within days. However, online renewal is only available if you are renewing an existing registration and do not need emissions testing or a title transfer.

What to do if you buy a used car from a private seller

When you buy a car from a private seller in Texas, you have 30 days to register it. During those 30 days, you can drive the car with the seller's old registration as long as you have proof of insurance in your name. After 30 days, you must have a new registration in your name or you will face a late fee.

Get the title signed by the seller and notarized. Both you and the seller must sign in front of a notary public. Many banks, credit unions, and UPS stores offer notary services for a small fee. Once the title is notarized, take it to your county tax assessor-collector along with your proof of insurance and other required documents.

If the seller cannot find the title, you can register the vehicle using a bill of sale, though the process takes longer. Ask your tax assessor-collector what additional documents you will need. Some counties require a VIN inspection or affidavit when there is no title.

Renewing your registration before it expires

Your registration expires on a date printed on your registration card. Texas sends renewal notices by mail about 60 days before expiration. If you do not receive a notice, do not wait — contact your tax assessor-collector to renew.

You can renew in person, by mail, or online (if your county offers it) up to 60 days before your registration expires. Renewing early means you will not accidentally drive with an expired registration. If your registration expires, you can still renew it, but you will owe a late fee on top of the regular registration fee.

If you move to a different Texas county, you do not need to re-register your vehicle. Your registration remains valid until the expiration date on your card. However, if you move out of Texas, you must register your vehicle in your new state.

Frequently Asked Questions

What if I lost my title?

Contact your county tax assessor-collector to request a duplicate title. You will need to provide proof of ownership, such as a bill of sale or previous registration. There is a fee for a duplicate title, usually $10 to $20. Processing takes one to two weeks.

Can I register a car that is not paid off?

Yes. If you have a loan on the vehicle, the lender's name will appear on the title as a lienholder. You can still register the car — the lienholder does not have to sign the registration paperwork. Bring the title as it is, with the lender's name on it.

What happens if I drive with an expired registration?

You can be pulled over and fined. The fine amount varies by county but typically starts around $100 to $200. You will also owe a late fee when you renew. Renew as soon as you realize your registration has expired to avoid additional fines.

Do I need to register my vehicle in the county where I live?

Yes. You must register your vehicle in the county where you live. If you move to a different county within Texas, you do not have to re-register until your current registration expires, but you should update your address with your tax assessor-collector.

How long does registration take if I go in person?

If you have all required documents and pass emissions testing (if required), registration takes about 30 minutes to an hour at the tax assessor's office. You receive your registration card and new license plates (if needed) the same day or within a few days by mail.
