Texas toll roads charge you by license plate, and you can pay online, by mail, or through an automatic payment plan
Texas toll roads are operated by regional authorities, not the state highway system. The largest operator is the Texas Department of Transportation (TxDOT), which runs toll roads in the Dallas-Fort Worth area, Houston, Austin, and San Antonio. Each region has its own payment system and customer service number, so the first step is identifying which toll authority operates the road you used.
You do not need a transponder or pre-loaded account to drive a toll road in Texas. The system reads your license plate as you pass through, and you receive a bill by mail or email. You can pay that bill online through the toll authority's website, set up automatic payments, or mail a check. If you do not pay within a set period (usually 30 days), late fees begin to accumulate.
Key Takeaways
- Texas toll roads bill you by license plate after you drive, so payment is not required upfront.
- Each toll authority operates independently, so you must contact the specific operator for your road to pay or set up an account.
- You can pay online, by mail, or through automatic bank withdrawal, and most authorities offer discounts if you prepay or use automatic payments.
- Unpaid tolls accrue late fees and can eventually result in vehicle registration holds or collection action.
- If you drive the same toll road regularly, a prepaid account or TxTag transponder usually costs less than paying per trip.
Identifying your toll authority and finding your bill
The toll road you used determines which authority to contact. TxDOT operates toll roads in four regions: North Texas Tollway Authority (Dallas-Fort Worth), Harris County Toll Road Authority (Houston), Central Texas Regional Mobility Authority (Austin), and Alamo Regional Mobility Authority (San Antonio). Private operators also run some roads, such as the LBJ Express in Dallas and the Westpark Tollway in Houston.
If you do not know which authority operates your road, start by searching the road name plus "toll payment" or call TxDOT's customer service at 1-888-468-9386. They can direct you to the correct authority. Once you identify the operator, visit their website to search for your bill by license plate number and vehicle information. Most authorities allow you to view and pay bills online without creating an account, though creating one makes tracking easier.
Bills are typically issued within 7 to 14 days of driving the toll road. If you have not received a bill and believe you drove a toll road, check the authority's website first—the bill may be posted there before arriving by mail.
Online payment and account setup
Each toll authority operates its own website, and payment is straightforward. You enter your license plate number, vehicle information, and the bill amount, then pay by credit card, debit card, or electronic check. Payment usually processes within one business day, and you receive a confirmation email.
Creating an account on the authority's website lets you set up automatic payments, view payment history, and receive email notifications when new bills are issued. Automatic payment is often the cheapest option because many authorities offer a small discount—typically 5 to 10 percent—for drivers who enroll. You authorize the authority to withdraw payment from your bank account or charge your card each time a bill is generated.
If you prefer not to use automatic payments, you can pay each bill individually online as it arrives. There is no fee for online payment, and it is faster than mailing a check.
Prepaid accounts and transponders
If you drive the same toll road multiple times per month, a prepaid account or transponder saves money. TxTag is the statewide prepaid transponder program operated by TxDOT. You purchase a transponder device (usually $15 to $20), load it with prepaid funds, and mount it on your windshield. When you drive through a toll plaza, the transponder communicates with the reader, and the toll is deducted from your balance.
TxTag accounts typically offer a 25 to 50 percent discount compared to paying by license plate, depending on the road and time of day. You can purchase a TxTag online or at retail locations, and you manage your account through the TxTag website. When your balance runs low, you can add funds online or set up automatic replenishment.
Some toll authorities also offer prepaid accounts without a transponder. You load money into an account tied to your license plate, and tolls are deducted as you drive. These accounts usually offer smaller discounts than TxTag but are simpler if you do not want to install a device. Check your specific authority's website to see what options are available.
Mailing a payment
If you prefer to pay by mail, include your bill or a copy of it with your check and send it to the address listed on the bill or on the authority's website. Mail payments take longer to process—typically 10 to 14 business days—so send your payment well before the due date to avoid late fees.
Write your license plate number on the check so the payment is applied to the correct account. Keep a copy of the bill and a record of when you mailed the payment in case there is a delay.
Late fees and unpaid toll consequences
If you do not pay a toll bill within 30 days, most authorities add a late fee of $5 to $10 per bill. If the bill remains unpaid after 60 days, additional collection fees may be added. After several months of non-payment, the toll authority can report the debt to a collection agency, which may pursue legal action or wage garnishment.
Unpaid tolls can also result in a hold on your vehicle registration renewal. When you attempt to renew your registration with the Texas Department of Motor Vehicles, the system checks for outstanding toll debt. If you have unpaid tolls, your registration will be denied until the debt is resolved.
If you have unpaid tolls, contact the toll authority as soon as possible. Many authorities offer payment plans for large debts or can waive some fees if you demonstrate financial hardship. It is much easier to resolve the issue before it reaches collection or registration hold status.
Disputing a toll charge
If you believe you were charged incorrectly—for example, if you were billed twice for one trip or if the toll amount is wrong—contact the toll authority's customer service. Most authorities have a dispute process on their website where you can submit a claim with details about the trip and the reason for the dispute.
Provide as much information as possible: the date and time of the trip, the road name, your license plate number, and an explanation of why you believe the charge is incorrect. Include photos or documentation if you have it. The authority will investigate and respond within 30 to 60 days. If the dispute is upheld, the charge will be removed or corrected, and any overpayment will be refunded.

Frequently Asked Questions
Do I have to pay a toll if I did not see a toll booth?
Yes. Many Texas toll roads use open-road tolling, which means there is no booth—the system reads your license plate as you drive through at full speed. You are still obligated to pay the toll. The bill will arrive by mail or email within two weeks.
Can I get a refund if I paid a toll twice by mistake?
Yes. Contact the toll authority's customer service and explain the duplicate charge. Provide the dates, times, and bill numbers if you have them. The authority will investigate and refund the duplicate charge if it is confirmed. This usually takes 30 to 60 days.
What happens if I move and do not receive my toll bill?
The bill will still be issued and late fees will accumulate if unpaid. Update your address with the toll authority as soon as you move. You can also create an online account and set up email notifications so you receive bills electronically regardless of your mailing address.
Is TxTag worth it if I only drive toll roads occasionally?
Probably not. TxTag has an upfront cost and is most cost-effective if you drive toll roads at least a few times per month. If you drive them only a few times per year, paying by license plate is simpler and cheaper overall.
Can I transfer my TxTag to a different vehicle?
Yes. You can move a TxTag transponder between vehicles by updating your account online or calling TxTag customer service. The transponder itself is reusable, though you may need to purchase a new mounting bracket for a different vehicle type.
