Texas toll roads charge you per trip, and you can pay through a transponder account, online, or by mail

Texas operates toll roads through regional authorities, and the payment method depends on which road you use and whether you have a transponder. The two largest systems are TxTag (operated by the Texas Department of Transportation) and EZTag (operated by Harris County). Smaller regions run their own systems. If you drive a toll road without a valid payment method on file, you will receive an invoice by mail weeks later, and if you do not pay it, the toll authority can place a hold on your vehicle registration renewal.

The fastest way to avoid late fees and registration holds is to set up a prepaid account before you need it. You can open an account online in about 10 minutes, add a payment method, and either mount a transponder in your vehicle or use your license plate number for pay-by-plate service. Most toll roads now accept both.

Key Takeaways

  • TxTag and EZTag are the two main toll systems in Texas, and you need an account with the system that operates the road you drive.
  • A transponder is a small device you mount on your windshield that charges your account automatically; pay-by-plate reads your license plate and sends you an invoice.
  • If you do not pay a toll invoice within the grace period, the toll authority can block your vehicle registration renewal until you settle the debt.
  • You can set up an account online, add funds, and request a transponder or set up pay-by-plate service without visiting an office.
  • Toll rates vary by road and time of day on some roads, and your account statement shows the exact charge for each trip.

Understanding TxTag and EZTag accounts

TxTag is the statewide system run by TxDOT and covers toll roads in the Dallas-Fort Worth area, Austin, San Antonio, and other regions. You can open a TxTag account at txdot.gov/txTag or by phone at 888-468-9824. EZTag serves the Houston area and is managed by Harris County. You open an EZTag account at eztag.org or by calling 281-875-3279.

Both systems work the same way: you create an online account, link a payment method (debit card, credit card, or bank account), and choose how you want to pay for tolls. You can request a physical transponder by mail, which takes about 5 to 10 business days to arrive. Once you mount it on your windshield, it communicates with toll readers as you pass through, and the charge is deducted from your account balance automatically.

If you do not want to wait for a transponder or prefer not to use one, both systems offer pay-by-plate service. This reads your license plate as you pass through the toll plaza and sends you an invoice by mail or email. Pay-by-plate is slower and usually costs slightly more per transaction, but it requires no equipment and works when ready.

Setting up your account and adding payment methods

To open a TxTag or EZTag account, you will need your driver's license or ID number, vehicle license plate number, and a valid payment method. Go to the website for the system you need, click the option to create a new account, and enter your information. The system will ask you to choose a username and password and set up a PIN for phone transactions.

After your account is created, add funds by linking a debit card, credit card, or bank account. Most accounts require a minimum opening balance of $10 to $20. You can set up automatic replenishment so that when your balance drops below a certain amount, the system charges your payment method and adds funds automatically. This prevents your account from running empty and triggering pay-by-plate invoices.

If you want a physical transponder, request one through your account dashboard. The system will mail it to your address at no charge. When it arrives, follow the mounting instructions to attach it to your windshield, usually on the upper driver's side. Then set up it in your account, and it will be ready to use within a few hours.

What happens if you do not pay a toll invoice

If you drive a toll road without an active account or transponder, the toll authority photographs your license plate and mails you an invoice. The invoice includes the toll amount plus a processing fee. You have a grace period—usually 30 days—to pay before late fees explore.

If you do not pay within that window, the toll authority adds a late fee (typically $25 to $50 per unpaid toll) and reports the debt to the Texas Department of Motor Vehicles. Once reported, the DMV will not renew your vehicle registration until you settle the toll debt. This means you cannot legally drive the vehicle, and if you are stopped, you face a ticket for expired registration.

To clear the hold, you must pay the toll amount, processing fee, and all late fees through the toll authority's website or by phone. Once payment is processed, the authority notifies the DMV, and the hold is lifted. You can then renew your registration normally.

Transponder versus pay-by-plate: which is right for you

A transponder is faster and cheaper. It charges your account when ready as you pass through, and most toll roads offer a small discount for transponder users. The device is free, and there are no monthly fees. The downside is that you have to wait for it to arrive by mail and mount it correctly on your windshield.

Pay-by-plate is more convenient if you do not want to wait or if you drive a toll road only occasionally. The system reads your plate, and you receive an invoice by mail or email within a few days. You then pay online, by phone, or by mail. Pay-by-plate usually costs slightly more per toll and takes longer to process, but it requires no equipment and works when ready once your account is open.

Many drivers use both: they keep a transponder mounted for frequent trips and let pay-by-plate handle occasional tolls on roads they do not use often. Your account can handle both methods at the same time.

Toll rates and how charges appear on your statement

Toll rates in Texas vary by road and, on some roads, by time of day. Congestion pricing roads like the Dallas North Tollway and some Austin toll roads charge higher rates during peak hours (usually 6 a.m. to 10 a.m. and 4 p.m. to 7 p.m. on weekdays) and lower rates during off-peak times. Your account statement shows the exact time and amount charged for each trip, so you can see why a particular toll cost what it did.

Most tolls range from $0.50 to $3.00 per trip, depending on distance and road. Some roads charge by the mile; others charge a flat rate per segment. Your account dashboard shows your current balance, recent transactions, and upcoming automatic replenishment dates. You can read statements for your records or for business expense reporting.

Replacing a lost or damaged transponder

If your transponder is lost, stolen, or damaged, contact the toll authority when ready. For TxTag, call 888-468-9824 or log into your account and request a replacement. For EZTag, call 281-875-3279 or use the website. The replacement transponder is usually free, but there may be a small shipping fee. The old transponder will be deactivated so it cannot be used fraudulently.

While you wait for the replacement, your account can still use pay-by-plate service. The system will read your license plate and send you invoices until the new transponder arrives and is activated. Once the new device arrives, mount it and set up it in your account, and you will return to automatic charging.

Frequently Asked Questions

Can I use a TxTag transponder on EZTag roads or vice versa?

No. TxTag and EZTag are separate systems that do not communicate with each other. If you drive both TxTag and EZTag roads regularly, you will need accounts with both systems and either two transponders or pay-by-plate service on one or both systems.

What if I move to a different state and no longer need my transponder?

Contact the toll authority and request to close your account. Any remaining balance will be refunded to your original payment method, usually within 7 to 10 business days. Return the transponder if you wish, though it is not required.

Can I use someone else's transponder in my vehicle?

Technically yes, but it is not recommended. The transponder is tied to the account holder's name, and if there is a dispute or late payment, the account holder is responsible. If you regularly drive someone else's vehicle, it is better to set up your own account and transponder.

How do I know which toll roads in Texas use which system?

TxTag covers most toll roads statewide except in the Houston area. EZTag covers Harris County toll roads. When you search for a specific toll road online, the road's website will tell you which system it uses and provide a link to open an account.

What if I dispute a toll charge on my account?

Log into your account and look for a dispute or inquiry option, or call the toll authority directly. Have your transaction details ready, including the date, time, and amount. The authority will investigate and either confirm the charge or issue a refund if an error occurred.
