What is the LLC Filing Deadline in Illinois?

Illinois LLCs must file an annual report before the first day of their anniversary month each year under 805 ILCS 180/50-1. The anniversary month is the month your LLC was originally formed. Your first annual report is due before the first day of that month in the year following formation. The filing fee is $75.00, and you must file online at https://apps.ilsos.gov/llcarticles/index.jsp.

Your Anniversary Month Deadline

Your LLC's filing deadline is tied to your anniversary month—the calendar month in which you formed your LLC. If you formed your LLC on March 15, 2024, your anniversary month is March. Your first annual report is due before March 1, 2025. All subsequent reports are due before March 1 each year.

File online with the Illinois Secretary of State, Department of Business Services. The $75.00 filing fee applies to each annual report.

Late Filing Penalties

Missing the deadline triggers automatic penalties under 805 ILCS 180/50-5:

Within 60 days late: A $100 late penalty applies if you file after the due date but within 60 days.
120+ days late: If your annual report remains unfiled 120 days from the original due date, your LLC faces administrative dissolution or revocation.

Once dissolved, reinstatement requires filing a reinstatement application, paying a $200 reinstatement fee, and paying all delinquent annual report fees and penalties.

What to Include

Your annual report must contain:

LLC legal name and file number
Jurisdiction of organization
Principal place of business or records office address
Names and business addresses of managers and members with manager authority
Registered agent and registered office information (if separately maintained)
