Texas toll roads are operated by regional authorities, not the state DMV, and you pay tolls directly to them—not through vehicle registration
Texas has no single toll road authority. Instead, the state has multiple regional toll authorities that own and operate specific toll roads in their areas. The largest is the Harris County Toll Road Authority (serving Houston), but there is also the Central Texas Regional Mobility Authority (Austin area), the North Texas Tollway Authority (Dallas-Fort Worth), and others. Each authority sets its own toll rates, collects its own payments, and manages its own roads. Your vehicle registration has nothing to do with toll payment—these are separate systems.
If you drive a toll road in Texas, you either pay at a toll booth, through an electronic tag, or receive an invoice by mail. The authority that operates that specific road is who you owe the money to, not the Texas Department of Motor Vehicles. Understanding which authority runs the road you use and how they prefer payment will save you late fees and confusion.
Key Takeaways
- Texas has multiple regional toll authorities, each operating different roads in different parts of the state—there is no single statewide toll authority.
- Toll payment is separate from vehicle registration and is not collected through the DMV or renewal process.
- You can pay tolls using an electronic tag (like TxTag), at a toll booth, or by mail invoice, depending on which authority operates the road.
- Unpaid tolls can result in late fees, vehicle registration holds, and collection action, so addressing toll debt early is important.
- Each toll authority has its own customer service number and website, so you need to contact the specific authority for the road you used.
The major toll authorities in Texas and the roads they operate
The Harris County Toll Road Authority operates toll roads in the Houston area, including the Hardy Toll Road, the Westpark Toll Road, and portions of the Sam Houston Tollway. The North Texas Tollway Authority runs the Dallas North Tollway, the President George Bush Turnpike, and the Sam Rayburn Tollway in the Dallas-Fort Worth region. The Central Texas Regional Mobility Authority manages toll roads around Austin, including sections of US 183 and State Highway 45.
The Fort Bend Toll Road Authority operates in the Fort Bend County area southwest of Houston. The Brazoria County Toll Road Authority runs toll roads in Brazoria County. Additionally, some toll roads are operated by the Texas Department of Transportation (TxDOT) directly, such as portions of the Sam Houston Tollway and some state highways with toll options. If you are unsure which authority operates a specific road, you can search by road name on the Texas toll authorities' websites or call the toll authority's customer service line.
How to pay tolls in Texas
The most common way to pay tolls in Texas is with a TxTag, an electronic toll tag that you mount on your windshield. TxTag is accepted on most toll roads statewide and automatically deducts tolls from a prepaid account. You can open a TxTag account online, by phone, or at a customer service center. The account requires a valid driver's license, vehicle registration, and a payment method (credit card, debit card, or bank account). Once activated, the tag reads as you pass through toll plazas, and your account is charged automatically.
If you do not have a tag, you can pay at a toll booth with cash or a credit card at some locations. However, not all toll plazas have staffed booths anymore—many have moved to all-electronic collection. If you pass through a toll plaza without a tag and without paying, the toll authority will photograph your license plate and mail you an invoice. This invoice includes the toll amount plus an administrative fee (typically $2 to $5). If you do not pay within a set time (usually 30 days), late fees accumulate, and the debt can be reported to the Texas DMV, which may place a hold on your vehicle registration renewal.
What happens if you do not pay a toll
Unpaid tolls in Texas can escalate quickly. After the initial invoice is mailed, you typically have 30 days to pay without additional penalties. If you do not pay by that important date, the toll authority adds a late fee (usually $5 to $10 per violation). If the debt remains unpaid for 60 to 90 days, the toll authority may report it to the Texas DMV, which can place a hold on your vehicle registration renewal. This means you cannot renew your registration until the toll debt is resolved.
In some cases, toll authorities pursue collection action, which can include sending the debt to a collection agency, filing a lawsuit, or placing a lien on your vehicle. The longer you wait, the more expensive the debt becomes. If you receive a toll invoice you believe is incorrect, contact the toll authority when ready with your vehicle information and the date you used the road. Most authorities have a dispute process and can review camera footage or tag records.
How to contact the right toll authority
Because Texas has multiple toll authorities, you need to know which one operates the road you used. If you received an invoice in the mail, it will show the authority's name and contact information. If you are trying to set up a TxTag account or dispute a toll, search for the specific authority by region or road name.
| Toll Authority | Service Area | Website |
|---|---|---|
| Harris County Toll Road Authority | Houston area | hctra.org |
| North Texas Tollway Authority | Dallas-Fort Worth area | ntta.org |
| Central Texas Regional Mobility Authority | Austin area | mobilityauthority.org |
| Fort Bend Toll Road Authority | Fort Bend County | fortbendtolls.com |
| Brazoria County Toll Road Authority | Brazoria County | brazoriatollroad.com |
Each authority's website has a customer service phone number, a way to open or manage a TxTag account, and a dispute process. You can also call 211 in Texas for general information about toll authorities in your area, though the toll authority's direct line is faster for account or payment questions.
The relationship between toll debt and vehicle registration
Toll debt does not prevent you from registering a vehicle initially, but it can prevent you from renewing your registration. Once a toll authority reports unpaid tolls to the Texas DMV, the DMV will flag your registration renewal. You will not be able to complete the renewal online or by mail until the toll debt is resolved. You can still renew in person at a DMV office, but you will need to show proof that you have paid the toll debt or set up a payment plan with the toll authority.
If you have a registration hold due to unpaid tolls, contact the toll authority that issued the debt, not the DMV. The toll authority can tell you the exact amount owed, any payment plans they offer, and what documentation you need to clear the hold. Once you pay or arrange a plan, the authority will notify the DMV, and the hold will be lifted within a few business days.
Frequently Asked Questions
Can I use one TxTag on multiple vehicles?
No. Each vehicle needs its own TxTag account and tag. You can manage multiple accounts online if you own several vehicles, but each tag is linked to one vehicle's registration. If you switch the tag between vehicles, tolls may be charged to the wrong account or the tag may not read properly.
What if I moved and the toll authority is sending invoices to my old address?
Contact the toll authority with your new address as soon as possible. Provide your vehicle registration number and the old address so they can update your account. If you have already received invoices at the old address, ask the authority to confirm they have your current contact information and whether any unpaid tolls are on your record.
Do I have to pay tolls if I am just passing through Texas?
Yes. Toll roads in Texas charge all vehicles, regardless of where they are registered. If you use a toll road without a TxTag and do not pay at a booth, you will receive an invoice by mail at the address on your vehicle registration. Out-of-state drivers should be aware that unpaid tolls can affect their ability to renew registration in their home state if the debt is reported to their DMV.
Can I set up a payment plan for unpaid tolls?
Some toll authorities offer payment plans for large debts, but policies vary. Contact the authority directly to ask about options. The sooner you reach out, the more likely they are to work with you before the debt is reported to the DMV or sent to a collection agency.
What is the difference between TxTag and other electronic toll tags?
TxTag is the primary electronic toll tag accepted statewide on most Texas toll roads. Some toll authorities also accept tags from other states' systems (like EZPass from northeastern states) through reciprocal agreements, but TxTag is the standard and most widely accepted option in Texas.
