TxTag is a toll payment system run by the Texas Department of Transportation, and you pay either by setting up an account with automatic charges or by mail after receiving an invoice
TxTag is the electronic toll collection system used on most toll roads in Texas, including the Dallas-Fort Worth area, Houston, Austin, and San Antonio. When you drive through a toll plaza without stopping, a transponder mounted on your windshield is read, and the toll is charged to your account. You do not pay at the booth — the system charges you later, either automatically from a linked payment method or by invoice if you choose to pay by mail.
The system is operated by the Texas Department of Transportation (TxDOT), and the toll amount varies by road, time of day, and congestion level. Some toll roads use dynamic pricing, meaning the toll goes up during peak hours and down during off-peak times. You can check your account online to see which tolls were charged and when.
Key Takeaways
- TxTag charges are applied to your account automatically if you set up a payment method, or you receive an invoice by mail if you do not.
- You can check your account balance and toll history on the TxTag website or mobile app at any time.
- If your account balance drops below a certain threshold, you will receive a notice to add funds before tolls are denied.
- Unpaid tolls result in late fees, vehicle registration holds, and potential collection action by the state.
- You can dispute a toll charge if you believe it was incorrect or if you were not the driver.
Setting up automatic payments or choosing to pay by invoice
When you open a TxTag account, you choose between two payment methods. Automatic payment links a credit card, debit card, or bank account to your account, and tolls are charged as you drive. This is the most common method and means you do not have to think about payment — the system handles it. You can set a minimum balance threshold, and the account will automatically replenish when your balance drops below that amount.
The alternative is pay-by-invoice, which means you receive a bill in the mail after tolls accumulate. This method does not require a payment method on file, but you must pay the invoice by the due date or face late fees. Pay-by-invoice is slower and requires you to remember to pay, so it is less common for regular toll users.
Most people who use toll roads regularly set up automatic payment because it is simpler and avoids the risk of forgetting to pay an invoice. You can change your payment method at any time through your TxTag account online.
What happens if your account balance runs low
TxTag sends you a notice when your account balance falls below a set threshold — usually around $10. This gives you time to add funds before your account runs out. You can add funds online, by phone, or at certain retail locations. The amount you add is up to you; many people add $25 to $50 at a time.
If your balance reaches zero and you drive through a toll plaza, the toll is not charged when ready. Instead, TxTag records the unpaid toll and sends you a notice. At this point, you have a grace period to add funds and pay the toll. If you do not pay within that period, late fees are added to your account.
If your account remains unpaid for an extended period, TxTag can place a hold on your vehicle registration renewal. This means you cannot renew your registration until the toll debt is paid. The state can also refer the debt to a collection agency, which will report it to credit bureaus and may pursue legal collection.
Late fees and penalties for unpaid tolls
Unpaid tolls accrue late fees that can quickly exceed the original toll amount. The exact fee structure depends on how long the toll remains unpaid, but fees typically start at around $25 to $50 per unpaid toll and can increase if the debt is referred to collections. After a certain period — usually 90 days — TxTag can suspend your vehicle registration or refer the account to a collection agency.
If your account is referred to collections, you may receive calls and letters from a debt collector. The debt will also appear on your credit report, which can affect your credit score and your ability to borrow money. Paying the original toll plus accumulated fees is the fastest way to resolve the debt and stop collection efforts.
Some people receive toll notices they believe are incorrect — for example, if they were not driving the vehicle or if the toll was charged twice. You can dispute a charge through your TxTag account or by contacting TxTag customer service directly. TxTag will investigate the dispute, and if it is found to be in error, the charge will be removed and any fees will be refunded.
How to check your account and manage your tolls
You can view your TxTag account online at the official TxTag website or through the mobile app. Your account shows your current balance, recent toll charges, and payment history. You can also see the date, time, and location of each toll you were charged, which is useful if you want to dispute a charge or straightforward track your spending.
From your account, you can add funds, change your payment method, update your contact information, and view notices from TxTag. If you have multiple vehicles, you can manage them all from one account and assign different transponders to each vehicle. You can also set up email or text alerts to notify you when your balance is low or when a toll is charged.
What to do if you lose your transponder or need a replacement
If your transponder is damaged, lost, or stolen, you can request a replacement through your TxTag account or by calling customer service. There is typically a small fee for a replacement transponder, usually between $5 and $15. TxTag will mail you a new transponder, which you mount on your windshield in the same way as the original.
Until your new transponder arrives, you can still use the toll roads, but tolls will be charged based on your license plate instead of your transponder. This is slower and may result in higher tolls or additional fees, so it is best to get a replacement as soon as possible. Once your new transponder arrives, mount it and your account will automatically recognize it.
TxTag versus other Texas toll payment methods
TxTag is the primary toll payment system in Texas, but some toll roads also accept other payment methods. TollTag is a competing system used on some roads, and Pay by Plate allows you to pay tolls based on your license plate without a transponder. However, Pay by Plate typically charges higher fees than TxTag and is meant for occasional users rather than regular toll drivers.
If you drive toll roads regularly in Texas, TxTag with automatic payment is usually the most cost-effective option. The transponder is free or low-cost, and automatic payment means you never have to worry about late fees or registration holds. If you only use toll roads occasionally, Pay by Plate may be simpler, though it will cost more per toll.
Frequently Asked Questions
Can I use TxTag on toll roads outside of Texas?
TxTag works only on toll roads in Texas. If you travel to other states with toll roads, you will need to use that state's toll payment system or pay cash at the toll booth. Some states have reciprocal agreements that allow certain transponders to work across state lines, but TxTag is not part of those agreements.
What if I think a toll charge is wrong?
Log into your TxTag account and look for the dispute option, or call TxTag customer service with the date, time, and location of the charge. TxTag will investigate and can remove the charge if it was an error. Keep records of when you were not driving the vehicle if you believe a toll was charged incorrectly.
How long does it take to add funds to my TxTag account?
Funds added online or by phone are usually available within a few minutes to a few hours. If you add funds at a retail location, they may take up to 24 hours to appear in your account. Set up automatic replenishment to avoid running out of funds.
Can I transfer my TxTag account to someone else?
TxTag accounts are tied to the account holder and cannot be transferred. If you sell your vehicle or no longer need the account, you can close it and request a refund of any remaining balance. The new owner of the vehicle will need to open their own TxTag account.
What happens if I move out of Texas?
You can close your TxTag account at any time and request a refund of your remaining balance. If you keep the account open but do not use it, there are no monthly fees, so you can leave it inactive. If you return to Texas later, you can reactivate the account.
