IL Registered Agent.org Review (2026)

IL Registered Agent.org takes on the Illinois registered agent job at $99 a year. That includes a registered office address in the state, plus scans of anything served on the company waiting in your account. Renewal does not change it: $99 again.

IL Registered Agent.org files the formation paperwork for $199, plus the state's filing fee. Your first year as registered agent comes with it; after that the agent is $99 a year. An EIN application adds $99, although the IRS issues EINs free.

IL Registered Agent.org will not file the Limited Liability Company Annual Report for you. In Illinois it comes around every year, due before the first day of the entity's anniversary month, and the state bills $75, so keep it on your list.

IL Registered Agent.org files the state registration for $199, with Illinois's $150 fee added. Year one as your registered agent is covered. You bring certificate of Good Standing or Existence, dated within 60 days.

Agent service alone costs $297 over three years with IL Registered Agent.org and $447 with Mainstay Filing, so $150 separates them. Mainstay Filing runs one agent plan that is valid in all fifty states and scans the first three government mailings a year free. The Mainstay Filing package is $199 a year and takes the annual report off your list; the IL Registered Agent.org route totals $397 over three years with the agent but without report filing. Illinois Registered Agent.co, the other Illinois agent we grade, charges the same $99 a year, and the two grades sit close together.
