  • American Rescue Plan Act of 2021 - Nontaxable Unemployment Benefits (Updated 5/13/21)

    ​IDOR has begun reviewing and adjusting accounts for qualifying taxpayers and will start sending letters in Mid-May explaining the update. This process is expected to take several months. If you are entitled to a refund, a paper check will be mailed to the address on file two to three weeks after the letter is sent. See the American Rescue Plan Act resource page for more information.

  • Contact IDOR via Email

    The Illinois Department of Revenue is taking proactive measures to prevent the spread of COVID-19. At this time, a limited number of taxpayer phone system agents are available. Due to the reduced number of agents taking calls, wait times may be longer than normal. Taxpayers can save time and avoid the wait by contacting the department by email.
