TxTag payments go directly to your toll account, not to a central office
TxTag is the electronic toll collection system used on toll roads in Texas, primarily managed by the Harris County Toll Road Authority (HCTRA) in the Houston area and by other regional authorities across the state. When you use a toll road with a TxTag transponder, the toll is charged to your account automatically. You pay that account balance through several methods: online, by phone, by mail, or in person at payment locations.
The account itself is tied to your transponder and vehicle registration. Payments reduce your account balance, and when the balance gets low, you can set up automatic replenishment so tolls keep working without interruption. If you do not pay, toll violations and late fees accumulate, and your vehicle registration can be suspended.
Key Takeaways
- You can pay your TxTag account online through the official TxTag website, by phone at the customer service number on your bill, by mail, or at authorized payment locations.
- Setting up automatic replenishment means your account refills when the balance drops below a threshold you choose, so you avoid toll violations from insufficient funds.
- Unpaid tolls result in violation notices, late fees, and eventually registration suspension, so paying promptly protects your ability to drive.
- If you move, change vehicles, or no longer need your transponder, you must update your account or close it to avoid charges for tolls you did not use.
Paying online through the TxTag website
The fastest way to pay is through the official TxTag website. Log in with your account number and password, review your balance and recent toll history, and choose how much to add to your account. You can pay with a debit card, credit card, or bank account transfer. The payment usually posts within one business day.
If you do not have an online account set up, you will need your transponder number (printed on the device itself) and your vehicle registration information to create one. The website also shows you which toll roads you have used, when, and the exact toll charged for each trip — useful if you want to verify charges or dispute a toll.
Automatic replenishment prevents toll violations
Automatic replenishment is the most reliable way to keep your account active. You set a minimum balance threshold (for example, $10) and a replenishment amount (for example, $50). When your balance falls below the threshold, the system automatically charges your payment method and adds the replenishment amount to your account.
Without automatic replenishment, your account can go negative if you use tolls faster than you expect. Once your balance is negative, you receive a violation notice with late fees added. The violation fee is separate from the toll itself and can be substantial. Setting up automatic replenishment takes a few minutes on the TxTag website and removes the risk of accidentally falling behind.
Paying by phone or mail
If you prefer not to pay online, you can call the TxTag customer service number listed on your bill or statement. Have your account number and payment method ready. A representative will process your payment over the phone, and it typically posts within one to two business days.
Mailing a check or money order is also an option, though it is slower. Write your account number on the check and mail it to the address shown on your bill. Allow at least two weeks for the payment to reach the office, be processed, and post to your account. During that time, tolls will continue to be charged, so mail payments work best if you have a buffer in your account balance.
What happens if you do not pay
Unpaid tolls trigger a violation notice, which includes the original toll amount plus a violation fee. If you do not pay the violation notice within the stated timeframe, additional late fees are added. The debt can grow quickly, and the toll authority reports unpaid violations to the Texas Department of Motor Vehicles.
Once reported, your vehicle registration can be suspended, which means you cannot legally drive the vehicle. You will not be able to renew your registration until the toll debt and all associated fees are paid in full. If you receive a violation notice, contact the toll authority immediately to discuss payment options or to dispute the charge if you believe it is incorrect.
Updating your account when your situation changes
If you sell your vehicle, buy a new one, or move to a different address, you need to update your TxTag account. Log into your online account and update your vehicle information or contact details. If you no longer use toll roads or no longer own a vehicle, you can close your account to stop any automatic charges.
Failing to update your account can result in tolls being charged to a vehicle you no longer own, or bills being sent to an old address where you do not receive them. This can lead to unpaid violations without your knowledge. Take a few minutes to update your account whenever your vehicle or address changes.

Frequently Asked Questions
Can I pay someone else's TxTag account?
Yes, you can make a payment toward any account if you have the account number. You do not need to be the account holder. Online, you can enter the account number and pay without logging in. By phone or mail, provide the account number and the toll authority will apply the payment to that account.
What if I think a toll charge is wrong?
Log into your account online and review your toll history. If you see a charge you believe is incorrect, contact TxTag customer service with the date, time, and location of the toll. Provide details about why you think the charge is wrong. The authority will investigate and may issue a credit if the charge was in error.
Does my payment go toward violation fees first or the toll itself?
Payments are typically applied to your account balance as a whole. If you have both tolls and violation fees owed, the toll authority will apply your payment to reduce the total debt. If you want to prioritize paying off a specific violation, call customer service to discuss payment arrangements.
Can I get a refund if I overpay my account?
Yes. If your account balance is positive and you no longer need the transponder, you can request a refund of the remaining balance. Contact TxTag customer service with your account number. Refunds are typically issued by check or to the original payment method within a few weeks.
What if my automatic replenishment payment fails?
If your card or bank account is declined, the system will attempt the charge again. If it fails multiple times, your account balance may go negative and you will receive a violation notice. Update your payment method on the website immediately if you know your card is expiring or your bank account is changing.
