How to File

  1. 1

    Gather Required Information

    Collect your LLC's current registered agent information, principal office address, and member/manager details. You'll also need your Illinois File Number from your original formation documents.

  2. 2

    Access the Illinois Secretary of State Website

    Visit the Illinois Secretary of State business services portal at ilsos.gov. Look for the LLC annual report filing section or business entity search to locate your LLC.

  3. 3

    Complete the Annual Report Form

    Fill out the annual report with current information about your LLC, including any changes to addresses, registered agent, or management structure since your last filing.

  4. 4

    Pay the $75 Filing Fee

    Submit payment for the $75 annual report fee online using a credit card or electronic check. If filing by mail, include a check payable to the Illinois Secretary of State. A series LLC pays $75 plus $50 for each series it has established.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state publishes about filing deadlines, fees, and the consequences of missing them, with the sources this page cites. It cannot tell you what your own company owes: the date turns on when and where you formed, states change these rules between our reviews, and in several states an entity-level tax falls due in a year when no report does. Confirm your own dates with the filing office named on this page before you rely on one here, because the penalty for missing a deadline can be administrative dissolution of the company.
