How to pay tolls in Texas
Texas has two main ways to pay tolls: TxTag, a prepaid account that charges your registered vehicle automatically, and Pay by Plate, which sends you a bill by mail after you drive through a toll plaza. TxTag is faster and cheaper—you get a small discount on each toll. Pay by Plate costs more per transaction and takes longer to process, but you do not need to set up an account in advance. Most toll roads in Texas accept both methods, though some newer toll projects may only accept TxTag initially.
Which method you choose depends on how often you use toll roads and whether you want to manage an account. If you drive tolls regularly, TxTag saves money and hassle. If you use tolls rarely, Pay by Plate works but costs more per toll and you will receive invoices in the mail.
Key Takeaways
- TxTag is a prepaid account linked to your vehicle that automatically deducts toll charges and offers a small discount per toll compared to Pay by Plate.
- Pay by Plate sends you an invoice by mail after you drive through a toll plaza, costs more per toll, and requires no advance setup.
- You can set up TxTag online through the TxTag website, by phone, or at a customer service center in most Texas cities.
- If you receive a Pay by Plate invoice, you must pay within a set timeframe or face late fees and potential vehicle registration holds.
- Toll roads in Texas are operated by different agencies—the Texas Department of Transportation (TxDOT), regional toll authorities, and private operators—and each may have slightly different payment rules.
Setting up TxTag for automatic toll payments
To open a TxTag account, you need your vehicle's license plate number, a valid Texas driver's license or ID, and a payment method (credit card, debit card, or bank account). You can register online at the TxTag website, by calling 888-468-9824, or in person at a TxTag customer service center. The online process takes about 10 minutes and your account becomes active when ready, though the discount does not explore until your transponder arrives and is mounted on your windshield.
When you set up the account, you choose a minimum balance—usually $25 to $100—and the account automatically charges your payment method when the balance drops below that threshold. This means you do not have to remember to add money; the system refills itself. If you lose your transponder or it stops working, TxTag will replace it, usually at no charge if the device failed.
TxTag works on most toll roads in the Dallas-Fort Worth area (operated by the North Texas Tollway Authority), Houston area (Harris County Toll Road Authority), Austin area (Central Texas Regional Mobility Authority), and San Antonio area (Alamo Regional Mobility Authority). It also works on some TxDOT toll roads. Before signing up, check which toll roads you use most often to confirm they accept TxTag.
Understanding Pay by Plate and when you receive invoices
Pay by Plate uses your vehicle's license plate to identify you when you drive through a toll plaza without a transponder. A camera reads your plate, and the toll authority looks up your vehicle registration to find your address. An invoice arrives by mail within two to four weeks, usually with a single charge for multiple tolls you drove during that billing period.
Pay by Plate costs more per toll than TxTag—typically 25 to 50 percent more depending on the toll road and the distance. For example, a toll that costs $1.50 with TxTag might cost $2.00 or more with Pay by Plate. If you use tolls frequently, these extra charges add up quickly. Pay by Plate is most practical for occasional toll use or if you are visiting Texas and do not have time to set up an account.
When you receive a Pay by Plate invoice, it will show the date you drove, the toll road, and the amount due. You must pay by the due date listed on the invoice. If you do not pay, late fees accumulate and the toll authority may place a hold on your vehicle registration renewal, preventing you from renewing your license plates until the toll debt is cleared.
Toll roads operated by different agencies in Texas
Texas toll roads are not all run by the same organization, and this affects which payment methods work where. TxDOT (Texas Department of Transportation) operates some toll roads and accepts both TxTag and Pay by Plate. The North Texas Tollway Authority (NTTA) runs toll roads in the Dallas-Fort Worth area and accepts TxTag and Pay by Plate. The Harris County Toll Road Authority (HCTRA) operates toll roads around Houston and accepts both methods.
The Central Texas Regional Mobility Authority (CTRMA) runs toll roads in the Austin area and accepts TxTag and Pay by Plate. The Alamo Regional Mobility Authority (AMRA) operates toll roads in San Antonio and also accepts both. Some toll roads are operated by private companies under long-term contracts with the state, and these typically accept TxTag and Pay by Plate as well, though you should confirm before driving.
If you travel across different regions of Texas, your TxTag account works on all of these systems. You do not need separate accounts for different toll authorities. Your single TxTag account is recognized statewide on participating toll roads.
What happens if you do not pay a toll bill
If you receive a Pay by Plate invoice and do not pay by the due date, the toll authority will send a second notice with a late fee added—typically $25 to $50 depending on the operator. If you still do not pay after the second notice, the debt may be referred to a collection agency or the toll authority may file a claim against your vehicle registration.
When a toll debt is reported to the Texas Department of Motor Vehicles, it creates a hold on your vehicle registration. You will not be able to renew your license plates until the toll debt is paid in full, including all late fees and collection costs. This hold remains in place even if you sell the vehicle, so it can affect your ability to transfer the title to a new owner.
If you believe an invoice is incorrect—for example, you did not drive that toll road or the charge is duplicated—contact the toll authority directly. Most agencies have a dispute process and will investigate if you provide details like the date, time, and toll road in question. Keep your documentation and follow up in writing if the phone dispute does not resolve the issue.
Discounts and special TxTag programs
TxTag offers a discount on every toll you pay compared to Pay by Plate, but some toll authorities also run special programs. The NTTA in Dallas-Fort Worth offers a TxTag Plus program that provides additional discounts during off-peak hours on certain toll roads. The HCTRA in Houston offers discounts for carpools and motorcycles on some toll roads. Check the website of the toll authority that operates the roads you use most to see if you may have access to for any of these programs.
Some employers and organizations negotiate group TxTag rates for their employees or members. If your employer offers this, you may be able to set up a TxTag account through them at a reduced cost. Military members and veterans may also may have access to for discounts on some toll roads; contact the toll authority directly to ask about veteran programs.
If you have a low income, some toll authorities offer reduced rates or payment plans. Contact the toll authority's customer service line to ask whether you may have access to. These programs vary by operator and are not widely advertised, so you may need to ask specifically.
Frequently Asked Questions
Can I use the same TxTag account on toll roads in different states?
TxTag only works on toll roads in Texas. If you travel to other states with toll roads, you will need to use their payment systems—for example, E-ZPass in the Northeast or FasTrak in California. Some states have reciprocal agreements, but you will need to check each state's toll authority website before traveling.
What if I move out of Texas but still owe a toll bill?
The toll authority will continue to send invoices to the address on file. If you do not pay, the debt may be referred to a collection agency and reported to credit bureaus. If you later try to renew your Texas vehicle registration or transfer the title, the registration hold will prevent you from doing so until the debt is paid.
Can I get a refund if I overpay my TxTag account?
Yes. If your TxTag account has a balance remaining when you close it or if you overpay, you can request a refund. Contact TxTag customer service by phone or through the website. Refunds typically take two to four weeks to process.
Do rental cars have TxTag transponders?
Most rental car companies in Texas equip their vehicles with TxTag transponders. When you rent a car, ask the rental agent whether the vehicle has TxTag and whether tolls will be charged to your rental agreement or billed separately. Some companies charge a daily fee for TxTag use in addition to the toll charges.
What if my TxTag transponder is stolen or damaged?
Contact TxTag customer service to report the loss or damage. They will deactivate the old transponder so it cannot be used fraudulently and will mail you a replacement, usually at no charge. Until the replacement arrives, you can drive tolls using Pay by Plate and will receive invoices by mail.
