IL Registered Agent.org Review (2026)

IL Registered Agent.org charges $99 a year for Illinois registered agent service, with the same $99 at renewal. The plan includes an in-state street address for the registered office and online scans of legal papers served on the company. The company also forms an Illinois LLC for $199 plus the state fee, counting the first year of agent service in that price. It also handles foreign registration in Illinois at $199 plus the state fee. Score note: a good match for an Illinois-only company that wants a flat agent price and files its own Limited Liability Company Annual Report.

The $99 plan, line by line

For $99 a year, IL Registered Agent.org acts as the Illinois registered agent. You receive an in-state street address for the registered office, and papers served on the company are scanned and posted to your account. Renewal holds at $99.

Using IL Registered Agent.org to form an Illinois LLC

IL Registered Agent.org prepares and files the formation document for $199; the state's filing fee is billed separately. Year one of registered agent service comes with it, and the agent runs $99 a year afterwards. The EIN application is a $99 extra, though the IRS charges nothing for an EIN.

Later, Illinois asks for the Limited Liability Company Annual Report every year, due before the first day of the entity's anniversary month with a $75 fee. IL Registered Agent.org does not file it, so it stays on your list.

Bringing an existing company into Illinois with IL Registered Agent.org

IL Registered Agent.org sends the registration to the state for $199, and Illinois's $150 fee is added. A year of registered agent service rides along. You supply certificate of Good Standing or Existence, issued within 60 days.

Where IL Registered Agent.org stands against Mainstay Filing

Agent service alone adds up to $297 over three years at IL Registered Agent.org and $447 at Mainstay Filing, a $150 spread. Mainstay Filing runs a single agent plan across all fifty states and scans the first three government mailings a year free. Mainstay Filing's formation package costs $199 a year and adds the annual report, while IL Registered Agent.org's LLC route totals $397 over three years with the agent but no report filing. Illinois Registered Agent.co is the other Illinois agent on the card; it charges the same $99 a year, and the two sit close together.
