Disputing a Toll in Texas

Texas has one of the largest toll networks in the country, split across TxTag (statewide), NTTA (Dallas–Fort Worth), and HCTRA (Houston). Because each authority bills separately, the agency name on your notice determines where you dispute.

Valid Reasons to Dispute a Toll in Texas

• The license plate was misread by the camera system.
• You were not the registered owner of the vehicle on the violation date in Texas.
• You had a valid, funded transponder account that should have covered the toll.
• You have proof the toll was already paid.
• The vehicle was sold, stolen, or rented to someone else at the time.
• The toll equipment malfunctioned or charged a duplicate toll.

Step-by-Step Filing Instructions

1. Confirm which authority issued the notice — TxTag, NTTA, or HCTRA — from the bill header.
2. Gather your toll bill, vehicle registration, and any proof of sale, theft, or a misread plate.
3. Draft a formal dispute letter citing the notice number, plate, date, and reason for the dispute.
4. Submit online through that authority's portal, or send by certified mail to the address on the notice.

Texas Toll Authority Mailing Addresses

• TxTag (toll payments) — P.O. Box 650749, Dallas, TX 75265-0749
• NTTA (ZipCash invoices) — P.O. Box 260928, Plano, TX 75026-0928
• HCTRA (Harris County) — 7701 Wilshire Place Drive, Houston, TX 77040
• Important: each entry is labeled by purpose (payment, contest/dispute, or violation). Send your dispute to the address shown for disputes, and always confirm against the exact address printed on your own notice, since agencies use different PO boxes for payments versus written disputes.

What to Expect After You File

Once your dispute is submitted, the toll authority reviews your evidence and the original toll image before responding — most decisions in Texas arrive within 30 to 90 days. Sending your letter by certified mail, or keeping the confirmation number from an online submission, gives you proof that you filed on time if you ever need to escalate.

If your dispute is approved, the charge is dismissed or reduced and any related late fees are typically removed. If it's denied, you usually still have the right to request a hearing or pay the reduced base toll. Either way, responding in writing before the deadline protects you from registration holds and collection activity, which are far harder to undo later.
