Resolution

  • The RT number is known as the WebFile number and is the access code in the upper left corner of Texas tax reports
    • It is also printed on most notices. 
    • Avalara calls it the RT number because it starts with RT (Example: RT123456).
  • If you do not have your WebFile number, you can contact TX at (800) 252-5555 24 hours a day, 7 days a week.
    • This automated system provides a WebFile number after you provide confidential information from a previously filed report.
    • You can request a duplicate report via this automated system if you cannot provide the confidential information.
