The Harris County Toll Road Authority runs most toll roads around Houston
The Harris County Toll Road Authority (HCTRA) operates the toll roads in the Houston area. HCTRA is a government agency created by Harris County to build, maintain, and collect tolls on specific highways. If you drive on toll roads in Houston, you are paying HCTRA, not a private company or the state.
HCTRA manages several major toll roads: the Katy Freeway (I-10), the Westpark Tollway, the Hardy Toll Road, the Tomball Tollway, the Fort Bend Tollway, and the Pasadena Freeway. Each road has different entry and exit points, and tolls vary based on the time of day and how far you travel. HCTRA also runs the toll lanes on US-290 and the managed lanes on I-45.
Understanding which agency runs the road you use matters because it determines where you pay your bill, how you dispute a charge, and what payment methods are available to you.

How to pay tolls: TxTag, toll-by-plate, and one-time payment
HCTRA offers three ways to pay tolls. A TxTag is a small electronic device you mount on your windshield that automatically deducts tolls from a prepaid account as you drive through toll plazas. TxTag is the cheapest option because you receive a discount on every toll you pay. You can open a TxTag account online at hctra.org, by phone at 713-849-2700, or in person at an HCTRA office.
If you do not want a TxTag, you can set up a toll-by-plate account. This method photographs your license plate as you pass through a toll plaza and charges your account. Toll-by-plate costs more per toll than TxTag because you do not receive the discount. You can open this account the same way you would open a TxTag account.
If you drive a toll road without a TxTag or toll account, HCTRA photographs your plate and sends you an invoice by mail. This is called a one-time payment. One-time payments cost the most and include an administrative fee. You have 30 days to pay the invoice online, by phone, or by mail.
What happens if you do not pay a toll bill
If you ignore a toll invoice, HCTRA will send you a second notice. If you still do not pay, HCTRA can place a hold on your vehicle registration renewal through the Texas Department of Motor Vehicles. This means you cannot renew your registration until you pay the outstanding tolls and fees.
HCTRA can also refer unpaid tolls to a collection agency, which will report the debt to credit bureaus and may contact you by phone or mail. Collection activity can lower your credit score and make it harder to borrow money in the future.
If you believe a toll charge is wrong, contact HCTRA before the bill becomes overdue. Disputes are easier to resolve if you raise them quickly. You can dispute a charge online through your account, by phone at 713-849-2700, or by mail.
Understanding toll rates and peak-hour pricing
HCTRA toll rates depend on which road you use and how far you travel. Most roads charge a flat rate per trip, but some roads use congestion pricing, which means the toll goes up during busy times and down during slow times. The managed lanes on I-45 and US-290 use this system.
On congestion-priced roads, tolls can range from less than $1 during off-peak hours to $5 or more during rush hour, depending on traffic. HCTRA adjusts prices every 15 minutes on some roads to keep traffic flowing. TxTag users see the current toll before they enter the managed lane, and toll-by-plate users are charged the toll that was in effect when they drove through.
You can see current toll rates and historical pricing on the HCTRA website. Rates change periodically, so check before you drive if you want to know what you will pay.
How to manage your HCTRA account online
You can view your toll history, check your account balance, and update your payment method through the HCTRA website at hctra.org. Log in with your account number and password to see all tolls charged in the past 90 days. You can also read statements and set up automatic payments so your account is never overdue.
If you lose your TxTag transponder or it stops working, you can order a replacement through your online account or by calling 713-849-2700. There is a fee for a replacement transponder, usually around $25, though this varies. You can also request a temporary toll-by-plate arrangement while you wait for your new TxTag to arrive.
If you move or change your phone number, update your account information online or by phone so HCTRA can reach you if there is a problem with your account.
Other toll operators in the Houston area
HCTRA is not the only toll operator in the region. The Texas Department of Transportation (TxDOT) operates some toll roads, including the Sam Houston Tollway and parts of the Grand Parkway. TxDOT toll roads use the same TxTag system as HCTRA, so you can use one TxTag account on both systems.
The Fort Bend Toll Road Authority operates some toll roads in Fort Bend County, south of Houston. These roads also accept TxTag, but you may need a separate account if you use toll-by-plate.
If you are unsure which agency operates a specific road, check the HCTRA website or call 713-849-2700. The staff can tell you which agency to contact and how to set up payment.
Frequently Asked Questions
Can I use my TxTag on roads outside Houston?
Yes. TxTag works on most toll roads in Texas, including roads operated by TxDOT and other toll authorities. Your account balance is shared across all TxTag-compatible roads. However, some toll roads outside the Houston area may use a different system, so check before you travel.
What if I think I was charged twice for the same trip?
Contact HCTRA within 30 days of the charge. You can dispute it online through your account, by phone at 713-849-2700, or by mail. HCTRA will review your toll history and the toll plaza records. If the charge was an error, they will refund the duplicate amount to your account.
Do I have to use a TxTag, or can I always pay by plate?
You can choose either method. TxTag is cheaper because of the discount, but toll-by-plate works if you prefer not to install a device. If you use neither, you will receive a one-time invoice by mail, which costs the most. There is no requirement to use TxTag on HCTRA roads.
How do I know if my TxTag is working?
Your TxTag should beep or flash when you pass through a toll plaza. If it does not, check your account online to see if the toll was charged. If the toll was not charged, your transponder may need a battery replacement or repositioning. Call 713-849-2700 to troubleshoot or order a replacement.
What if I move out of Texas but still owe tolls?
You are still responsible for paying any outstanding tolls. HCTRA can place a hold on your vehicle registration in Texas, and unpaid tolls can be reported to collection agencies. Pay your bill before you move, or contact HCTRA to set up a payment plan if you cannot pay in full.
