In Short: Illinois LLC Annual Report
Every Illinois LLC, domestic or foreign, files an annual report with the Illinois Secretary of State once a year, before the first day of the month it was formed or admitted.
- Who files: every domestic LLC and every foreign LLC admitted to do business in Illinois, active or not.
- Due date: before the first day of your anniversary month. The filing window opens 60 days before that date.
- Fee: $75, plus $50 for each series with a certificate of designation.
- Late penalty: $100 once the report is still missing on the first day of the second month after the anniversary month, plus $100 for each further year.
- If you never file: the state marks the LLC not in good standing and dissolves it 120 days after its notice of delinquency. Reinstatement costs $200 plus every missed report and penalty.
Illinois ties the annual report to the month your LLC was born. An LLC formed in June has a June anniversary month, so its report is due before June 1 every year. Miss it and the Secretary of State marks the company delinquent the next day, refuses to file anything else for it, and starts the clock toward administrative dissolution.
This guide covers who files, the exact deadline and window, the fee, what the report asks for, how to file online or by mail, and what happens if you file late. Every figure comes from the Illinois Limited Liability Company Act, 805 ILCS 180, which the Secretary of State enforces.

Who Must File an Illinois LLC Annual Report?
Section 50-1 of the LLC Act requires every limited liability company organized in Illinois and every foreign LLC admitted to transact business in Illinois to file an annual report. There is no exemption for single-member LLCs, LLCs with no revenue or LLCs that are inactive. As long as the LLC exists on the state’s records, the report is due.
A foreign LLC is one formed in another state, such as Wyoming or Delaware, that registered in Illinois because it does business there. It files the Illinois report on the anniversary of its Illinois admission, on top of whatever its home state requires.
When Is the Illinois LLC Annual Report Due?
Under 805 ILCS 180/50-1, the report and fee must reach the Secretary of State within the 60 days immediately before the first day of the LLC’s anniversary month. The anniversary month is the month the articles of organization were filed, or for a foreign LLC, the month it was admitted.
- Formed in June: the window opens in early April and the report is due before June 1.
- Formed in January: the window opens in early November and the report is due before January 1.
- Formed in October: the window opens in early August and the report is due before October 1.
The first report falls due in the year after formation. An LLC formed in June 2026 files its first annual report before June 1, 2027. A report mailed by first-class mail before the first day of the anniversary month counts as on time if you can prove the mailing date, but filing online removes that question entirely.
How Much Does the Illinois Annual Report Cost?
The filing fee is $75 under 805 ILCS 180/50-10. A series LLC pays $75 plus $50 for each series that has a certificate of designation in effect on the last day of the third month before the anniversary month. An LLC with three active series pays $225.
Illinois charges LLCs no franchise tax, so the annual report is the single state filing that keeps an Illinois LLC in good standing from year to year.
What Information Does the Annual Report Ask For?
Section 50-1 sets the contents. Have this ready before you start:
- The LLC’s exact legal name and its Illinois file number.
- The registered agent’s name and the street address of the registered office in Illinois.
- The street address of the principal place of business.
- The name and business address of every manager, and of any member with the authority of a manager.
- Any other information the Secretary of State asks for to verify the fee, such as series designations.
A manager signs the report. If the LLC has no managers, a member designated by the members signs it. The information has to be current as of the date you sign, so the report is also your chance to correct an outdated address or remove a former manager.
How to File the Illinois LLC Annual Report: Step by Step
- Find your anniversary month and file number. Search the LLC on the Secretary of State business services site. The record shows the formation date and the file number you need to file.
- Wait for the 60-day window. The state accepts the report only in the 60 days before the first day of the anniversary month.
- Choose online or mail. The online filing on the Secretary of State site is the faster route. Paper filers use Form LLC-50.1 and mail it to the Limited Liability Division in Springfield.
- Confirm or update the details. Check the registered agent, principal address and managers. Update anything that changed.
- Pay the $75 fee. Add $50 for each series. Pay by card online, or by check or money order payable to the Secretary of State by mail.
- Save the confirmation. Keep the filed report with your LLC records and set a reminder for next year’s window.
What Happens If You File Late?
Illinois escalates in three stages, all set out in the LLC Act:
- Delinquent the day after the deadline. Under 805 ILCS 180/50-15, an LLC that has not filed and paid before the first day of its anniversary month is declared delinquent and not in good standing. The state will not file any amendment, report or other document for it until the delinquency is cleared.
- $100 penalty after the grace month. If the report is still missing on the first day of the second month after the anniversary month, the Secretary of State adds a $100 penalty. For an LLC with a June anniversary month, that date is August 1. Another $100 accrues for each year or part of a year from the second year of delinquency until the LLC returns to good standing.
- Administrative dissolution. Under Section 35-25 and Section 35-30, the Secretary of State mails a notice of delinquency to the registered office. If the LLC does not cure the default within 120 days of that notice, the state issues a certificate of dissolution.
A dissolved LLC can be reinstated under Section 35-40 by filing an application for reinstatement, filing every report that came due, and paying all fees and penalties. The reinstatement application itself costs $200. If another business has taken the name in the meantime, the LLC has to adopt a new one.
Illinois Annual Report Tips for Non-Resident Owners
Owners who live outside the US run into two avoidable problems with Illinois. First, the state’s delinquency notice goes to the registered office, so a registered agent who does not forward mail leaves you unaware of the problem until dissolution. Second, a delinquent LLC cannot get a certificate of good standing, and US banks and payment processors ask for one when you open or review an account.
Put the anniversary month in your calendar with a reminder 60 days ahead, and file as soon as the window opens. Filing early in the window costs nothing extra and leaves time to fix a rejected report.
Keep Your Illinois LLC in Good Standing
Filing the LLC Annual Report on time is what keeps your LLC listed as active with the state. Banks, payment processors and new partners ask for proof of that status, and the document that shows it is a Illinois certificate of good standing. For the full picture of what the state charges each year, see our breakdown of Illinois LLC costs, and if you have not formed the company yet, start with our guide on how to start an LLC in Illinois.
Most missed filings trace back to one problem: the state’s reminder went to an old address. A registered agent service that scans and forwards state mail closes that gap. If a deadline has already passed, our guide on what happens when you miss an annual report deadline walks through the fix, and our LLC annual report guide for every state covers the rules in other states where you are registered.
