What a TxTag bill is and who receives one

A TxTag bill is an invoice from the Texas Department of Transportation (TxDOT) for tolls you've driven on Texas toll roads. If you have a TxTag transponder mounted on your vehicle, the system automatically charges your account each time you use a tolled road. When your prepaid balance runs low or you've accumulated charges, TxDOT sends you a bill to replenish your account or pay what you owe.

You'll receive a TxTag bill in the mail if your account balance drops below a certain threshold, or if you've driven tolls without maintaining a funded account. The bill shows which toll roads you used, the dates of travel, and the total amount due. Unlike a traffic ticket or citation, a TxTag bill is straightforward a request for payment for the tolls you've incurred.

Not all Texas toll roads use TxTag. Some use different systems like EZTag (Harris County) or TollTag (North Texas Tollway Authority). If you're unsure which system applies to your toll road, check your bill or the road's official website.

Key Takeaways

  • A TxTag bill is an invoice for tolls you've driven on Texas toll roads, sent when your prepaid account balance is low or depleted.
  • You can pay online through the TxTag website, by phone, by mail, or in person at a TxTag customer service center.
  • Paying your TxTag bill on time prevents late fees, account suspension, and potential vehicle registration holds.
  • If you believe charges on your bill are incorrect, you can dispute them through TxDOT's customer service within a set timeframe.
  • Setting up automatic replenishment can prevent future bills by keeping your account funded as you drive.

How to pay your TxTag bill

The fastest way to pay is online at www.txt.ag (the official TxTag website). Log in with your account number and password, review the charges, and pay by credit card, debit card, or electronic check. Payment typically posts within one business day.

You can also pay by phone by calling TxDOT's customer service line. Have your bill and payment method ready. Mailing a check is an option, but it takes longer—mail it to the address shown on your bill and allow at least two weeks for processing. Some TxTag customer service centers accept in-person payments; locations and hours are listed on the TxTag website.

Do not ignore a TxTag bill. Unpaid tolls can result in late fees, account suspension, and a hold placed on your vehicle registration renewal. If you're having trouble paying, contact TxDOT customer service to discuss payment arrangements before the bill becomes overdue.

Late fees and what happens if you don't pay

If you don't pay your TxTag bill by the due date, TxDOT will add a late fee to your account. The amount varies, but late fees typically range from $5 to $25 depending on how far past due the account is. These fees stack up quickly if the bill remains unpaid for several months.

Beyond late fees, an unpaid TxTag bill can trigger a registration hold. This means you won't be able to renew your vehicle registration until the toll debt is settled. TxDOT reports unpaid tolls to the Texas Department of Motor Vehicles, which enforces the hold at renewal time. You may also receive collection notices or see the debt referred to a collection agency.

In some cases, TxDOT can suspend your TxTag account entirely, preventing you from using toll roads until the balance is paid. If you're facing financial hardship, contact TxDOT before the bill becomes severely overdue—they may be able to work out a payment plan.

Disputing charges on your TxTag bill

If you believe a charge is incorrect—for example, if you were double-charged for a single trip or charged for a road you didn't use—you can dispute it. Log into your TxTag account online and look for a dispute or inquiry option, or call TxDOT customer service with your bill and the specific charge in question.

Have details ready: the date of the disputed trip, the toll road name, and the amount charged. TxDOT will investigate and either remove the charge, adjust your account, or explain why the charge is correct. Disputes are typically resolved within 30 to 60 days, though the timeframe can vary.

Keep copies of your bills and any correspondence with TxDOT. If you believe the dispute was resolved incorrectly, you can escalate it to a supervisor or file a formal complaint with TxDOT's customer service department.

Setting up automatic replenishment to avoid future bills

The easiest way to stay on top of tolls is to set up automatic replenishment on your TxTag account. This means your account will automatically charge your credit card, debit card, or bank account whenever your balance drops below a set amount—usually $10 or $25, depending on your preference.

To enable automatic replenishment, log into your TxTag account online, go to account settings, and select the replenishment option. Choose your trigger amount (the balance at which the system will charge you) and your payment method. You can also set a maximum replenishment amount so you're not charged more than you want at once.

With automatic replenishment active, you'll rarely receive a bill in the mail. Instead, small charges will be added to your card as needed, spreading the cost over time. This also prevents late fees and registration holds because your account stays current.

Understanding the difference between TxTag and other Texas toll systems

Texas has multiple toll systems, and they don't all work the same way. TxTag is operated by TxDOT and covers most state toll roads. EZTag is the Harris County toll system (Houston area). TollTag is operated by the North Texas Tollway Authority (Dallas-Fort Worth area). Each system has its own billing, customer service, and payment methods.

If you drive on roads operated by different systems, you may need accounts with more than one. A TxTag transponder won't work on EZTag or TollTag roads, and vice versa. Check your bill to see which system issued it, then contact that system's customer service for payment and account questions.

Some toll roads allow you to pay without a transponder by using a license plate-based system, though this typically costs more per trip. If you use toll roads regularly, having the correct transponder for your area saves money and simplifies billing.

What to do if you've moved or your contact information changed

If you've moved and didn't update your address with TxTag, your bills may be going to an old address and you might miss payment important date. Log into your TxTag account online and update your mailing address, email, and phone number when ready. You can also call TxDOT customer service to make these changes over the phone.

Updating your information also ensures you receive important notices about your account, such as low balance alerts or suspension warnings. If you've moved out of state or no longer use toll roads, you can close your TxTag account to prevent future charges.

If you believe you've missed bills because of an address change, contact TxDOT to explain the situation. They may be willing to waive or reduce late fees if you can show the bills were sent to an incorrect address.

Frequently Asked Questions

Can I pay my TxTag bill with cash?

Most online and phone payment methods don't accept cash. However, some TxTag customer service centers may accept cash payments in person. Call ahead to confirm your nearest location accepts cash and their hours of operation.

What if I don't have a TxTag account but drove on a toll road?

If you drove on a toll road without a transponder, TxDOT will photograph your license plate and send you an invoice by mail. This is called a "pay by plate" charge and typically costs more than using a TxTag. Pay it promptly to avoid late fees and registration holds.

Will an unpaid TxTag bill affect my credit score?

An unpaid TxTag bill itself won't show on your credit report unless it's referred to a collection agency. However, if it goes to collections, it can damage your credit. Pay your bill or contact TxDOT about a payment plan before it reaches that stage.

Can I transfer my TxTag account to a different vehicle?

Yes. Log into your account online or call TxDOT customer service to update your vehicle information. You'll need your new vehicle's license plate number and VIN. The transponder itself can usually be moved between vehicles.

How long do I have to pay a TxTag bill before it becomes overdue?

The due date is printed on your bill, typically 30 days from the bill date. If you don't pay by that date, late fees begin to accrue. Check your bill for the exact due date and pay before then to avoid penalties.
