Illinois LLC Annual Report — Step 6 of 8
Illinois's Annual Report deadline runs backward from most states — it's due before your anniversary month starts, not by the end of it. Get this detail wrong and you'll file a full month late.
Every Illinois LLC files an Annual Report every year for $75. It's due before the first day of your LLC's anniversary month — the month it was originally approved — not by the last day of that month. Form in June and your report is due by May 31 every year, not June 30. Your first report isn't due until the year after formation. Miss it and you'll owe a $100 late penalty, with administrative dissolution risk after 120 days past due.

What Illinois's Annual Report Involves
The Annual Report keeps your LLC's core details current with the Secretary of State. Illinois's version has one important quirk to understand:
- Fee: $75 — this applies whether you file online or by mail, with no discount for either method.
- Due window: before the first day of your anniversary month — the calendar month your LLC was originally approved. This is the reverse of most states, which give you until the end of that month.
- First report timing: not due until the year after your LLC was formed.
- Filed with: the Illinois Secretary of State's Department of Business Services — online for LLCs with 8 or fewer members, or by mail (Form LLC-50.1) for larger LLCs, power-of-attorney signatures, or reinstatements.
- Pre-filled reminder mailed automatically — the state sends a pre-filled report to your registered agent roughly 45 days before it's due.

How to File
- File online for instant processing — find your File Number on your original welcome letter or the Illinois Business Entity Search.
- Review your information — confirm your LLC's name, registered agent, and principal address; you cannot change your registered agent through this filing.
- List your managers or managing members — up to 6 officers and 6 directors can be entered electronically; larger LLCs must file by mail.
- By mail: send Form LLC-50.1 with a check or money order for $75, payable to "Secretary of State," to the Department of Business Services in Springfield. Mail filings take 10–15 business days.
- File up to 45 days early — Illinois strongly recommends filing within this window to avoid last-minute technical issues.
This is the single most common Illinois filing mistakeMost states give you until the last day of your anniversary month to file. Illinois requires filing before the first day of that month — meaning the deadline actually falls in the prior month. An LLC formed in June must file by May 31, not June 30. This single-month difference catches even experienced business owners off guard.
