Registered Agent in Illinois: What It Is, How It Works, and Why You Need One
Illinois requires every LLC to continuously maintain a registered agent and registered office under 805 ILCS 180/1-35. The agent must be an individual resident of Illinois or another person authorised to transact business in the state. Failure to appoint and maintain an agent is a standalone ground for administrative dissolution under 805 ILCS 180/35-25(3). A resigning agent must give the LLC 10 days notice before filing, and the resignation takes effect no sooner than 30 days after filing.
