IL Registered Agent.org Review (2026)

IL Registered Agent.org is a Illinois registered agent service at $99 a year, the same $99 at renewal. You get a registered office address inside the state, and a scan of each legal paper served on the company lands in your online account. Starting an Illinois LLC with this company runs $199 above the state fee, and the first year as your agent is thrown in. Registering an outside company in Illinois through it runs $199 on top of the state fee. Bottom line: it suits an Illinois-only company that likes a fixed agent price and will handle its own Limited Liability Company Annual Report.

IL Registered Agent.org compared with Mainstay Filing and the rest of the list

For the agent alone, three years with IL Registered Agent.org come to $297 and with Mainstay Filing to $447, a difference of $150. Mainstay Filing has a single agent plan that is good in every state and scans the first three government mailings a year free. Mainstay Filing's package is $199 a year and includes the annual report; with IL Registered Agent.org the LLC route adds up to $397 over three years including the agent, but report filing is not covered. Illinois Registered Agent.co, the other Illinois agent we shortlisted, asks the same $99 a year, and the two end up near each other.
