Every Illinois LLC, and every foreign LLC registered in Illinois, files an annual report with the Secretary of State in the 60 days before the first day of its anniversary month. Under 805 ILCS 180/50-10 the fee is $75, plus $50 for each series with a certificate of designation, as of October 2026. Miss it and the company is declared not in good standing, with a $100 penalty once you're past the second month after the anniversary month.
Illinois runs its LLC annual report on the company's own calendar, not a single state deadline. That's handy, because it spreads the work through the year, but it also means nobody else is going to remember your date for you. Here's what the Illinois Limited Liability Company Act says about the report, the fee and the penalties.
Who has to file an Illinois annual report
Section 50-1 says each LLC organized in Illinois and each foreign LLC admitted to transact business in Illinois must file an annual report. It doesn't matter whether the company traded that year or how much it earned. If it exists on the state's records, the report is due.
What goes in the report
The statute keeps the content short. The report states:
- the name of the LLC
- the street address of its registered office in Illinois and the name of its registered agent at that address
- the street address of its principal place of business
- the names and business addresses of all managers, and any member with the authority of a manager
- anything else the Secretary of State needs to administer the Act and check the fees due
The information has to be current as of the date the report is signed. It's made on the Secretary of State's forms and signed by a manager or, if there isn't one, a member chosen by the members.
When the Illinois annual report is due
The report and fee must be delivered to the Secretary of State within the 60 days immediately before the first day of the anniversary month. Your anniversary month is the month your company was organized in Illinois, or admitted if it's a foreign LLC.
So if your LLC was formed in June, your filing window opens around the start of April and closes at the end of May. The statute also says that if you can prove the report and fee were mailed, sealed, addressed and with postage paid, before the first day of the anniversary month, that counts as filing on time.
If the Secretary of State finds a mistake and sends the report back, you don't get penalised for lateness as long as you correct it and return it within 60 days.
Illinois annual report fees
Section 50-10 sets these fees, as of October 2026:
| Filing | Fee in 805 ILCS 180/50-10 |
|---|---|
| Annual report of an LLC or foreign LLC | $75, plus a penalty if late |
| Annual report of a series LLC | $75 plus $50 for each series with a certificate of designation in effect |
| Statement of change of registered office or agent, or a statement of correction | $25 |
| Reinstatement of an LLC | $200 |
| Articles of organization (for comparison) | $150, or $400 for a series LLC |
| Certificate or certified copy of a document | $25 |
Notice that changing your registered agent on its own costs $25, while the annual report already shows your agent. If your agent has changed and your report is due soon, it's worth checking whether you can deal with both in one go.

What happens if you file late
Section 50-15 says the Secretary of State declares an LLC delinquent and not in good standing if it hasn't filed the report and paid the fee before the first day of its anniversary month. The same applies if it hasn't appointed a registered agent within 60 days of being told its agent resigned.

If you still haven't fixed it before the first day of the second month after the anniversary month, the penalty is $100, plus $100 for each year or part of a year from the second year of delinquency until you're back in good standing or reinstated. While you're delinquent, the Secretary of State won't file any other documents for you, and can tell anyone who asks that your company isn't in good standing.
That second point matters more than the fee. Banks, lenders and bigger clients often ask for a certificate of good standing before they sign, and you can't get one while you're delinquent.
A late report also blocks other filings. If you were planning to amend your articles, add a series or change your agent, you'll need to clear the delinquency first, which turns a $75 job into a bigger one.

How to stay on top of it
- Find your anniversary month on your articles of organization and put a reminder at the start of the 60-day window, not the end.
- Check your registered agent and manager details before you file, so the report doesn't need correcting.
- If you run a series LLC, count the series with a certificate of designation in effect, because each adds $50.
- Keep proof of the filing or mailing date with your company records.
