How Texas tolls work and who collects them
Texas tolls are collected by regional authorities, not a single statewide system. The Texas Department of Transportation (TxDOT) oversees toll roads, but each metropolitan area runs its own collection through entities like the Harris County Toll Road Authority (Houston), the North Texas Tollway Authority (Dallas-Fort Worth), and the Central Texas Regional Mobility Authority (Austin). When you drive a toll road, you either pay at a booth, through an electronic tag, or receive an invoice later — the method depends on which road you use and which region operates it.
Most Texas toll roads now use open-road tolling, meaning you do not stop at a booth. Instead, cameras read your license plate or an electronic tag mounted on your windshield. If you do not have a tag and do not pay within a set window (usually 30 days), the toll authority mails you an invoice with the toll amount plus a processing fee. Unpaid tolls can lead to late fees, vehicle registration holds, and collection actions.
Key Takeaways
- Texas toll roads are operated by regional authorities in Houston, Dallas-Fort Worth, Austin, San Antonio, and other areas, each with separate payment systems and tag programs.
- Electronic toll tags (TxTag, EZTag, TollTag) are the cheapest way to pay because they offer discounts of 10 to 50 percent compared to pay-per-use rates.
- If you do not have a tag, license plate tolling charges you the full rate and adds a processing fee; you have about 30 days to pay before late fees explore.
- Unpaid tolls can result in registration holds, collection agency referral, and civil judgments, so addressing invoices promptly is important.
- You can dispute a toll charge if you believe it was issued in error, but you must contact the specific toll authority within their stated window.
Electronic toll tags and how to get one
The fastest and cheapest way to pay tolls in Texas is with an electronic tag. The three main programs are TxTag (used in Houston and surrounding areas), EZTag (Dallas-Fort Worth), and TollTag (Austin and Central Texas). Each tag is a small transponder you mount on your windshield. When you drive through a toll plaza, the tag communicates with overhead readers and charges your prepaid account. Tag holders typically pay 30 to 50 percent less per toll than drivers who pay by license plate.
To open a tag account, you visit the toll authority's website, provide your vehicle information and payment method, and order the tag. Most tags arrive within one to two weeks. You then mount it on your windshield and fund your account with a credit card, debit card, or bank account. Some programs require a minimum balance; others charge a small monthly account fee if your balance drops below a threshold. Once active, the tag deducts tolls automatically as you drive.
If you drive across multiple regions (for example, Houston to Dallas), you will need tags from each authority because the systems do not communicate. A TxTag works only in the Houston area; you cannot use it on Dallas toll roads. Some travelers carry multiple tags or use license plate tolling when traveling outside their home region.
License plate tolling and pay-by-invoice
If you do not have a tag, Texas toll roads photograph your license plate and bill you by mail. This method is called pay-by-plate or license plate tolling. The toll authority runs your plate through the Department of Motor Vehicles database, finds your address, and sends you an invoice. You then have a window — usually 30 days — to pay online, by phone, or by mail.
Pay-by-plate costs more than using a tag. A single toll might cost $1.50 with a tag but $2.50 or more without one. Additionally, the authority adds a processing fee (typically $1 to $3 per transaction) to cover the cost of mailing and handling. If you drive tolls frequently without a tag, these fees add up quickly.
Payment is straightforward: the invoice includes a reference number, the toll amount, the processing fee, and instructions for paying online. Most toll authorities accept credit cards, debit cards, and bank transfers. Paying within the stated window avoids late fees. If you miss the important date, the authority typically adds a late fee (ranging from $5 to $25 depending on the region) and may refer the debt to a collection agency.
What happens if you do not pay a toll
Unpaid tolls in Texas carry real consequences. After the initial invoice window closes, the toll authority sends a second notice with a late fee. If you ignore that, the debt may be referred to a collection agency, which can report the account to credit bureaus and pursue legal action. Some toll authorities also work with the Texas Department of Motor Vehicles to place a hold on your vehicle registration renewal.
A registration hold means you cannot renew your license plates until you settle the toll debt. This can prevent you from legally driving the vehicle and may result in fines if you are stopped by law enforcement. In some cases, toll authorities file civil judgments against drivers, which can lead to wage garnishment or bank account levies, though this is less common for smaller debts.
The best course of action if you receive a toll invoice is to pay it within the stated window. If you believe the toll was issued in error — for example, your vehicle was not on the road that day, or you already paid — contact the toll authority directly with evidence (such as a receipt or credit card statement) and request a review. Most authorities have a dispute process, though you typically must initiate it within 60 to 90 days of the invoice date.
Regional toll systems and their coverage areas
Texas has five major toll-operating regions, each with its own tag program and payment structure. Understanding which system covers your area helps you choose the right payment method and avoid surprises.
| Region | Toll Authority | Tag Program | Coverage Area |
|---|---|---|---|
| Houston | Harris County Toll Road Authority | TxTag | Houston metro, surrounding counties |
| Dallas-Fort Worth | North Texas Tollway Authority | EZTag | Dallas, Fort Worth, surrounding areas |
| Austin | Central Texas Regional Mobility Authority | TollTag | Austin metro, surrounding counties |
| San Antonio | San Antonio Toll Authority | TxTag | San Antonio metro |
| Corpus Christi | Corpus Christi Regional Mobility Authority | TxTag | Corpus Christi area |
If you live or work in one region but travel to another, you will encounter tolls from multiple authorities. For example, a trip from Houston to Dallas crosses into the North Texas Tollway Authority's jurisdiction, where your TxTag will not work. You will be billed by license plate for those tolls. Keeping a tag from each region you frequent is the most economical approach.
Disputing a toll charge or correcting account errors
If you receive a toll invoice you believe is incorrect, you have the right to dispute it. Common reasons for disputes include being charged twice for the same toll, being billed for a toll you did not incur, or receiving an invoice for a vehicle you no longer own. Each toll authority has a dispute process, though the steps and timelines vary.
To dispute a charge, contact the toll authority directly using the reference number on your invoice. Most authorities accept disputes by phone, email, or through their website portal. You will need to explain why you believe the charge is wrong and provide supporting evidence — a receipt, credit card statement, proof of sale if you sold the vehicle, or a statement that you were not in the area on that date. The authority then investigates and either reverses the charge, adjusts your account, or explains why the charge is valid.
Disputes must typically be filed within 60 to 90 days of the invoice date, though some authorities extend this window if you can show good cause. If you dispute a charge before paying it, the authority may still add late fees if the dispute is not resolved in your favor. It is often safer to pay the invoice and then request a refund if the dispute is upheld, rather than risk additional fees by withholding payment.
Toll payment options for commercial vehicles and frequent drivers
Commercial drivers and fleet operators can set up business accounts with toll authorities, which offer volume discounts and simplified billing. Instead of paying per vehicle, a fleet account consolidates all tolls into a single monthly invoice. This is useful for trucking companies, delivery services, and businesses with multiple vehicles.
To open a commercial account, contact the toll authority's business services department. You will need to provide your business license, tax ID, and information about your fleet. The authority will assign you a dedicated account manager and set up billing terms. Commercial accounts often include discounts of 10 to 25 percent off standard tag rates, depending on volume and the authority's policies.
Frequent personal drivers can also benefit from tag accounts with automatic replenishment. Instead of manually adding funds, you authorize the toll authority to charge your credit card or bank account when your balance drops below a set amount. This ensures you never run out of funds and keeps your account active without manual intervention.
Frequently Asked Questions
Can I use the same toll tag in different Texas cities?
No. TxTag works only in Houston and surrounding areas, EZTag only in Dallas-Fort Worth, and TollTag only in Austin and Central Texas. If you travel between regions, you need a tag from each authority or you will be billed by license plate. Some drivers carry multiple tags; others use pay-by-plate when traveling outside their home region.
What if I move to a different state — do I still owe Texas tolls?
Yes. Unpaid tolls remain your responsibility regardless of where you move. The toll authority can pursue collection through the courts, report the debt to credit bureaus, and in some cases work with other states' motor vehicle departments to enforce payment. Settling the debt before you leave Texas is the best approach.
How long does a toll invoice stay valid before it becomes uncollectible?
Texas toll authorities can pursue collection for several years, typically four to ten years depending on the authority and whether the debt has been referred to a collection agency or resulted in a court judgment. There is no automatic expiration date, so old invoices can resurface. Paying promptly is always the safest option.
Can I get a refund if I overpay my toll account?
Yes. If your tag account has a credit balance, you can request a refund through the toll authority's website or by calling their customer service. Refunds typically take one to two weeks to process. Some authorities allow you to transfer the balance to a new account instead of requesting a refund.
What if my toll tag is damaged or stops working?
Contact your toll authority's customer service and request a replacement tag. Most authorities send a new tag at no charge within one to two weeks. In the meantime, you will be billed by license plate if you drive tolls. Once your new tag arrives and is activated, the authority will credit any license plate charges to your tag account.
