Texas toll tags charge your linked payment method automatically each time you use a tolled road
A toll tag is a small electronic device mounted on your windshield that communicates with toll plazas as you drive. When you pass through a tolled road in Texas, the tag sends a signal, and the toll is charged to the payment method you registered with the toll authority. You do not stop or pay at a booth — the system reads your tag and bills you later.
Texas has two main toll tag systems: TxTag, operated by the Texas Department of Transportation (TxDOT), and Toll-by-Plate, which photographs your license plate instead of using a tag. Most tolled roads in the Dallas-Fort Worth, Houston, and Austin areas use one of these systems. The payment method you choose determines how and when your account is charged.
Key Takeaways
- TxTag accounts can be funded with a credit card, debit card, or bank account, and charges post within a few days of driving.
- You can set up automatic replenishment so your account refills when the balance drops below a threshold you choose.
- Toll-by-Plate charges your vehicle registration address on file, and you can pay online, by phone, or by mail if you do not have a tag.
- Account statements and payment history are available through the TxTag or toll authority website, and you can update your payment method anytime.
- If your tag malfunctions or you lose it, contact the toll authority immediately to avoid being billed as a toll-by-plate customer at a higher rate.
Setting up automatic payments on your TxTag account
When you open a TxTag account, you link a payment method — a credit card, debit card, or bank account — to fund it. The toll authority does not charge you upfront; instead, tolls are deducted from your account balance as you drive. Once your balance falls below a certain amount, you can set the account to automatically replenish itself.
To enable automatic replenishment, log into your TxTag account online or call the TxTag customer service line. You choose the trigger amount (the balance at which replenishment happens) and the replenishment amount (how much to add each time). For example, you might set it to add $50 when your balance drops to $10. Charges to your payment method occur a few days after each replenishment, and you receive a confirmation email.
If you prefer not to use automatic replenishment, you can manually add funds to your account whenever you choose. This gives you more control but requires you to monitor your balance and top up before it runs out. Many drivers find automatic replenishment simpler, especially if they use tolled roads regularly.
Paying tolls without a tag using Toll-by-Plate
If you do not have a TxTag or your tag is not working, the toll plaza photographs your license plate and sends you an invoice. This system is called Toll-by-Plate. You will receive a bill in the mail at the address registered with your vehicle's title, usually within two weeks of driving the toll road.
You can pay a Toll-by-Plate invoice online through the toll authority's website, by phone, or by mailing a check. Payment methods typically include credit cards, debit cards, and bank transfers. Toll-by-Plate rates are usually higher than TxTag rates — sometimes 50 percent more — so it is meant as a temporary option, not a permanent payment method.
If you receive a Toll-by-Plate invoice and believe it was an error, you can dispute it through the toll authority's website or by calling customer service. Keep your receipt or confirmation number if you pay online, as you may need it to track the dispute.
Checking your account balance and payment history
You can view your TxTag account balance, recent tolls, and payment history by logging into your account on the TxTag website or mobile app. The site shows each toll transaction, the date and time you passed through, the toll amount, and your remaining balance. This information updates within a few days of each toll.
If you have set up automatic replenishment, you can see a record of each replenishment charge and the date it posted to your payment method. You can also download statements for your records or for tax and business purposes if you use tolled roads for work.
If you notice a toll charge you do not recognize or believe is incorrect, contact TxTag customer service with the date, time, and location of the toll. They can investigate whether the charge was legitimate or if your tag malfunctioned.
Updating your payment method or account information
You can change your linked payment method, billing address, or contact information anytime through your TxTag account online. Log in, go to account settings, and update the fields you need to change. Changes take effect immediately for new charges, though pending replenishments may still use the old payment method if they are already in process.
If your credit card or bank account expires or is compromised, update it as soon as possible to avoid failed replenishment attempts. If a replenishment fails, TxTag will attempt to charge again, but if all attempts fail, your account balance may drop to zero and you will be billed as a Toll-by-Plate customer at the higher rate until you add funds.
If you move to a new address, update your billing address in your account so that any Toll-by-Plate invoices (if they occur) are sent to the correct location. You can also update your phone number and email to ensure you receive account notifications.
What to do if your toll tag stops working
If your tag is damaged, lost, or not reading properly, contact TxTag customer service immediately. They can deactivate the old tag so you are not charged at the higher Toll-by-Plate rate while you wait for a replacement. TxTag will mail you a new tag at no charge, which usually arrives within one to two weeks.
While you wait for the replacement, you will be billed as a Toll-by-Plate customer if you use tolled roads. Once your new tag arrives and is activated in your account, future tolls will be charged at the TxTag rate again. If you were charged Toll-by-Plate rates during the interim, contact customer service to ask whether those charges can be adjusted to the TxTag rate.
To avoid damage, keep your tag clean and protected from extreme heat or direct sunlight. Do not cover it with stickers or reflective material, as this can interfere with the signal. If you are unsure whether your tag is working, you can test it by driving through a toll plaza and checking your account within a few days to confirm the toll posted.
Understanding TxTag rates and discounts
TxTag rates vary by road and region. Most tolled roads in Texas charge between $0.50 and $2.00 per toll, depending on the distance and the specific toll road. Some toll roads offer discounts during off-peak hours or for frequent users, though this varies by authority.
TxTag customers always pay less than Toll-by-Plate customers on the same road. The difference can be significant — sometimes 50 percent or more — so maintaining an active tag and account is worth the effort. Some toll authorities also offer discounts for low-income drivers or commercial vehicles, which you can ask about when you open your account.
You can view the toll rates for specific roads on the TxTag website or the website of the local toll authority that operates the road. Rates are public information and do not change based on your account type or payment method.
Frequently Asked Questions
Can I use one TxTag on multiple vehicles?
No. Each vehicle needs its own tag registered to its license plate. If you own multiple vehicles, you can set up separate TxTag accounts for each or link them to one master account for easier management. Contact TxTag to discuss multi-vehicle account options.
What happens if my account balance goes negative?
TxTag will attempt to charge your linked payment method to bring the balance back to zero. If that charge fails, you will owe the negative amount plus any late fees. Contact customer service immediately to resolve it and prevent your account from being sent to collections.
Can I get a refund if I have a credit balance on my TxTag account?
Yes. If your account has a positive balance and you no longer need the tag, you can request a refund through your account or by calling customer service. Refunds are typically processed within two to four weeks and returned to your original payment method.
Do I need a TxTag to drive on Texas toll roads?
No. You can drive without a tag and pay through Toll-by-Plate, but you will be charged a higher rate. TxTag is optional but significantly cheaper if you use tolled roads regularly.
How long does it take for a toll charge to appear on my account?
Toll charges typically appear in your TxTag account within one to three days of driving through a toll plaza. Charges to your payment method (for automatic replenishment) post a few days after the replenishment is triggered.
