Managing toll payments in Central Texas is streamlined through the official PayMobilityBill.com portal. Operated by the Central Texas Regional Mobility Authority (Mobility Authority), this website serves as the primary hub for drivers to resolve invoices and manage their accounts for several major Austin-area roadways.
This article covers everything from online payment steps and saving money with electronic tags to avoiding “Habitual Violator” penalties.

What is www.paymobilitybill.com?
Www.PayMobilityBill.com is the secure online platform used to pay “Pay By Mail” invoices issued by the Mobility Authority. It is specifically for tolls incurred on the following roads:
- 183A Toll

Important Note: In the Austin area, you may also receive bills from TxTag (TxDOT) for roads like Loop 1 (North MoPac), SH 45 N, SH 45 SE, and SH 130.
How to Use the Online Portal
The online service center allows you to perform several tasks beyond just paying a bill. Users can check account balances, sign up for electronic invoicing, and chat with a customer service representative.
Login Requirements
To access your account online, you will need your license plate number and one of the following:
- Mobility Authority Account Number (indicated on your notice)

How to Save 33% on Your Tolls
The most cost-effective way to travel on Central Texas toll roads is by using an electronic tag. Tag users automatically save 33% compared to the “Pay By Mail” rate. The Mobility Authority accepts several tags, including:

- K-TAG (Kansas)
- PIKEPASS (Oklahoma)
- BancPass (Reloadable cash option)
Alternative Payment Methods
If you prefer not to use the online portal, the Mobility Authority provides several other ways to resolve your balance:
- By Phone: Call the automated attendant 24/7 at (833) 762-8655 (Toll-Free) or (512) 410-0562 (Local).
- By QR Code: Scan the QR code on the front of your mailed invoice to be taken directly to a personalized, secure payment portal.
- In Person: Visit walk-up centers at 1321 Rutherford Lane, Suite 120 or 12719 Burnet Road in Austin. Payments are also accepted at many participating retail stores.
- By Mail: Send payment to the address listed on your specific invoice.
Late Fees and the Habitual Violator Program
Ignoring toll notices can lead to significant financial and legal consequences. CTRMA invoices typically incur a $15 late fee per invoice.
Habitual Violator Status
Under Texas law, a driver is deemed a Habitual Violator if they have 100 or more unpaid toll charges within a 12-month period and have been issued at least two non-payment notices. Consequences include:
- Registration Blocks: You will be unable to renew your vehicle registration.
- Road Bans: You may be prohibited from using all Mobility Authority roadways.
- Legal Action: Operating a vehicle in violation of a ban is a Class C misdemeanor with fines up to $500, and repeat offenses can result in vehicle impoundment.
Security Warning: Avoid Smishing Scams
The Mobility Authority has issued alerts regarding phishing and “smishing” (SMS phishing) scams.
- The Mobility Authority will never ask for personal information via text or email.
- Official notices are sent only through the U.S. Postal Service.
