Illinois Registered Agent.co Review (2026)

Illinois Registered Agent.co serves as your Illinois registered agent for $99 a year. The plan supplies an in-state street address for the registered office and scans legal papers served on the company to your online account. At renewal the price stays $99.

Illinois Registered Agent.co files the formation document for $199, and the state's filing fee goes on top. The first year of registered agent service is included; after that the agent is $99 a year. An EIN application costs $99 extra, although the IRS issues EINs free.

Illinois expects the Limited Liability Company Annual Report every year, due before the first day of the entity's anniversary month, with a $75 state fee. Illinois Registered Agent.co does not file it, so that job stays with you.

Illinois Registered Agent.co files the registration with the state for $199, plus Illinois's $150 fee. A year of registered agent service is part of it. You provide certificate of Good Standing or Existence, dated within 60 days.

For the agent alone, Illinois Registered Agent.co comes to $297 over three years and Mainstay Filing to $447, a gap of $150. Mainstay Filing sells one agent plan for all fifty states and scans the first three government mailings a year free. Mainstay Filing's formation package is $199 a year and includes the annual report; Illinois Registered Agent.co's LLC route comes to $397 over three years with the agent but without report filing. IL Registered Agent.org, the other Illinois agent on our list, charges the same $99 a year, and the two finish close together.
