What a Texas Toll Tag is and how payment works

A toll tag is a small electronic device mounted on your windshield that automatically charges tolls to an account as you drive through toll roads in Texas. The most common toll tag is the TxTag, operated by the Texas Department of Transportation (TxDOT), though some toll roads accept other tags like EZTag or Toll-by-Plate. When you drive through a toll plaza, cameras read your tag and deduct the toll amount from your prepaid account balance.

Payment happens in two stages: first, you set up an account and add money to it (called a prepaid balance); second, tolls are automatically deducted each time you use a toll road. You do not pay per trip at a booth — the system charges your account in the background. If your balance runs low, most systems will send you a notice and allow you to add more money before the account stops working.

TxTag accounts are tied to a specific vehicle and license plate, though you can link multiple vehicles to one account if you want. The tag itself is free, but you must maintain a positive balance to use toll roads without triggering violation notices.

Key Takeaways

  • TxTag is the primary toll tag system in Texas and works by deducting tolls automatically from a prepaid account balance.
  • You can set up a TxTag account online through the TxTag website, by phone, or in person at a TxTag customer service center.
  • Adding money to your account can be done online, by phone, by mail, or at retail locations, and most methods process within one to three business days.
  • If your balance drops below a certain threshold, TxTag will notify you and may suspend your tag until you replenish the account.
  • Toll violations occur when you drive through a toll plaza without a valid tag or sufficient balance, and unpaid violations can result in fines and registration holds.

Setting up a TxTag account

To create a TxTag account, visit the official TxTag website (txtag.org) and select "Open an Account." You will need your vehicle's license plate number, vehicle identification number (VIN), and a valid driver's license or ID. The online process takes about 10 minutes and asks for your name, address, phone number, and email.

If you prefer not to set up an account online, you can call TxTag customer service at 888-468-9824 or visit a TxTag customer service center in person. Centers are located in the Dallas-Fort Worth, Houston, and Austin areas. When you open an account by phone or in person, staff will mail your toll tag to the address on file, which typically arrives within five to seven business days.

Once your account is open, you must add money before using toll roads. Your tag will not work until your account has a prepaid balance. Some people set up automatic replenishment, which adds money to the account when the balance falls below a set amount — this prevents the tag from becoming inactive.

Adding money to your TxTag account

You can add funds to your TxTag account through several methods. Online payment through txtag.org is the fastest and most common option; you can use a credit card, debit card, or bank account. Online payments typically post within one business day. By phone, call 888-468-9824 and a representative will process your payment using a credit or debit card; this also usually posts within one business day.

By mail, send a check or money order to the TxTag mailing address (listed on the website) along with your account number. Mail payments take seven to ten business days to process. At retail locations, some H-E-B stores and other retailers accept TxTag payments in cash or card; check the TxTag website for participating locations near you.

The minimum initial payment is typically $20, though this can vary. If you set up automatic replenishment, you choose the trigger amount (the balance at which new funds are added) and the replenishment amount (how much is added each time). For example, you might set it to add $50 when your balance drops below $10.

What happens when your balance runs low or becomes negative

TxTag monitors your account balance in real time. When your balance drops below $5, most accounts receive an email or text notification (depending on your contact preferences). This gives you time to add money before the tag stops working. If your balance reaches zero or goes negative, your tag becomes inactive and will not open toll plazas.

If you drive through a toll plaza without a valid tag or with an inactive account, the toll road operator will issue a violation notice. This notice includes the toll amount plus a violation fee, which varies by toll road but typically ranges from $25 to $50 per violation. Violation notices are mailed to the address on your vehicle registration.

If violations go unpaid, the Texas Department of Motor Vehicles can place a hold on your vehicle registration renewal. This means you cannot renew your registration until the violations and fees are resolved. Paying the violation through the toll road operator's website or by phone will clear the hold, though this may take a few business days to process.

Checking your balance and transaction history

Log into your TxTag account on txtag.org to view your current balance and recent transactions at any time. The account dashboard shows each toll charge, the date and time it occurred, the toll road used, and your remaining balance. You can also read or print a statement for your records.

By phone, call 888-468-9824 and a representative can tell you your balance and recent activity. Some people prefer this method if they do not have regular internet access. You can also request a paper statement be mailed to you, though this takes longer than checking online.

Reviewing your transaction history regularly helps you catch errors or unauthorized use. If you notice a charge you did not make or believe a toll was charged incorrectly, contact TxTag customer service with the date, time, and toll road location. They can investigate and issue a credit if the charge was in error.

Transferring your tag to a different vehicle

If you sell your vehicle or want to use your toll tag on a different car, you must update your account with the new license plate number and vehicle identification number. Log into txtag.org, go to "Manage Account," and select "Update Vehicle Information." Enter the new plate and VIN, and the change takes effect when ready.

Your prepaid balance transfers with you — you do not lose any money when you change vehicles. The tag itself (the physical device) can be moved to the new vehicle's windshield, or you can request a new tag be mailed to you. If you are transferring the tag to a different vehicle, make sure the new vehicle's registration is current before using toll roads.

If you are selling your vehicle to someone else, you should remove the tag from the windshield and either keep it for your next vehicle or return it to TxTag. Leaving a tag on a vehicle you no longer own can cause confusion if the new owner uses toll roads, as charges may still go to your account.

Resolving common payment and account issues

If your payment was rejected, check that your credit card or bank account information is correct and that the card has not expired. Online payments sometimes fail due to incorrect billing zip codes or address mismatches. Try updating your payment method on txtag.org and resubmitting, or call 888-468-9824 to process the payment by phone.

If you believe a toll charge is wrong, gather the details: the date, time, toll road name, and the amount charged. Contact TxTag with this information and they will review the transaction. Errors can occur if a tag malfunctions or if the system reads the wrong vehicle, though this is rare. TxTag will issue a credit if they confirm an error.

If you have not received your toll tag after two weeks, contact TxTag to confirm your mailing address is correct. Tags are sometimes returned to sender if the address is incomplete or incorrect. You can request a replacement tag be mailed or pick one up at a customer service center.

Frequently Asked Questions

Can I use my TxTag on toll roads outside of Texas?

TxTag works only on toll roads operated by TxDOT and some regional toll authorities in Texas. It does not work on toll roads in other states. If you travel to other states with toll roads, you will need to use that state's toll system or pay tolls at the booth.

What if I lose my toll tag or it gets damaged?

Contact TxTag customer service and request a replacement tag. There is usually no charge for a replacement. A new tag will be mailed to you within five to seven business days, and your account balance transfers to the new tag automatically. Your account number stays the same.

Can I get a refund if I move out of Texas or stop using toll roads?

Yes. If you no longer use toll roads, you can request a refund of your remaining balance by contacting TxTag customer service. Refunds are typically issued as a check mailed to your address on file and take two to four weeks to arrive. You must close your account to receive the refund.

What is Toll-by-Plate and how is it different from TxTag?

Toll-by-Plate is a system that charges tolls to your vehicle based on your license plate, without requiring a physical tag. Some toll roads in Texas accept Toll-by-Plate, though you will receive an invoice by mail instead of having an account you manage. TxTag is faster and more convenient because charges are deducted when ready from your prepaid balance.

Do I have to use a toll tag, or can I pay tolls another way?

Most toll roads in Texas require either a TxTag or Toll-by-Plate. Some toll plazas have a cash lane, but these are becoming less common. If you do not have a tag and drive through a toll plaza, you will receive a violation notice. Setting up a TxTag account is the most straightforward way to use toll roads regularly.
