Having it done for you
Mainstay Filing prepares and files the annual report as part of $199 a year, with Illinois’s fee passed through at cost. The agent-only plan ($149) does not include it. Your agent itself is a separate matter: changing it in Illinois costs $25 (805 ILCS 180/1-35).

Is a Illinois “annual report due” letter from a company real?
