TxTag bills can be paid through the official TxTag website at txtag.org, by phone, by mail, or at a TxTag customer service center

TxTag is the toll tag system used on Harris County toll roads in the Houston area. When you use a toll road, the charges appear on your TxTag account, and you receive a bill. The fastest way to pay is through txtag.org itself — you log in with your account number and password, then pay directly from a bank account or credit card. If you prefer not to use the website, you have several other options, each with different timing and requirements.

The method you choose affects when your payment posts and whether you incur late fees. Understanding each route helps you avoid missed payments and keeps your account in good standing.

Key Takeaways

  • Online payment through txtag.org is the fastest method and posts within one to two business days when you pay by bank account.
  • Phone payments can be made by calling the TxTag customer service line, and you will need your account number and a valid payment method ready.
  • Mail payments take seven to ten business days to arrive and post, so send them well before your due date to avoid late fees.
  • Late payments trigger fees and may result in toll violations being reported to the Texas Department of Motor Vehicles.

Paying through txtag.org online

Log in to your account at txtag.org using your account number and password. If you do not have a password, use the "Forgot Password" link on the login page to reset it. Once logged in, select "Pay Now" or "Make a Payment" — the exact wording varies slightly depending on your account type.

You will be asked to enter the amount you wish to pay and choose a payment method. TxTag accepts bank account transfers (ACH), which typically post within one to two business days at no extra charge. Credit and debit card payments are also accepted but may carry a processing fee of around 2.5 percent, depending on the card type. After you submit the payment, you will receive a confirmation number when ready. Save this number for your records.

If your account shows a past-due balance, you can pay the full amount or a partial amount. Paying in full clears the account; partial payments reduce the balance but do not stop late fees from accruing if the account remains unpaid past the due date.

Paying by phone

Call the TxTag customer service line at 713-224-8294. Have your account number ready, along with the payment amount you intend to send. A representative will walk you through the payment process over the phone.

Phone payments are processed the same way as online payments — you can pay by bank account or credit card. The representative will confirm your payment method, process the transaction, and provide you with a confirmation number. This method takes the same one to two business days to post as online ACH payments.

Phone lines are typically open Monday through Friday during business hours. If you call outside these hours, you may reach an automated system that allows you to leave a message, though this does not process a payment when ready.

Paying by mail

Write a check or money order payable to TxTag. Include your account number on the check itself. Mail it to the address shown on your bill — this is usually the TxTag billing office in Houston, but the exact address may vary depending on your account type.

Mail payments take seven to ten business days to arrive and be processed. If your bill is due in fewer than ten days, mailing a check risks a late payment. For this reason, mail is best used when you have at least two weeks before the due date, or when you are paying a bill that is not yet overdue.

Keep a copy of the check or money order number and the date you mailed it. If the payment does not post within two weeks, contact TxTag customer service with this information so they can trace it.

Paying at a TxTag customer service center

TxTag operates customer service centers in the Houston area where you can pay in person. You can pay by cash, check, debit card, or credit card at these locations. Visit txtag.org and select "Locations" to find the center nearest you, along with hours of operation.

In-person payments are processed when ready and your account is updated the same day. This method is useful if you prefer to handle the transaction face-to-face or if you want to discuss your account with a representative in real time.

What happens if you miss a payment

If your bill remains unpaid past the due date, TxTag charges a late fee. The amount varies but typically ranges from $5 to $25 depending on how far past due the account is. These fees are added to your balance, increasing the total amount owed.

If the account stays unpaid for an extended period, TxTag may report the violation to the Texas Department of Motor Vehicles. This can result in vehicle registration holds or other penalties. Additionally, unpaid tolls can affect your ability to renew your vehicle registration or obtain a new toll tag.

If you are unable to pay your full balance, contact TxTag customer service to discuss payment plan options. Some accounts may be may be able to access for a plan that spreads the balance over multiple months, though this typically requires a down payment and may include additional fees.
