Illinois Annual Report Filing: Due Date, Fee, and How to File

Every LLC formed or registered in Illinois files an annual report with the Illinois Secretary of State to keep its good standing. The report itself is short, the official filing fee is $75, and the deadline is tied to your company's anniversary month. Understanding how those pieces fit together helps you avoid the state's $100 late penalty and the dissolution process that follows extended neglect.

When the Illinois Annual Report Is Due

Illinois assigns every LLC a deadline based on its own calendar rather than a single statewide date. Your annual report is due before the first day of your LLC's anniversary month, meaning the month in which the company was originally formed. If your Articles of Organization were approved on June 18, for example, every future report must be filed before June 1.

The filing window opens 60 days before the first day of your anniversary month, which gives you roughly two months to complete a filing that usually takes minutes. The requirement comes from the Illinois Limited Liability Company Act at 805 ILCS 180/50-1, and a report that has not been filed by the first day of the anniversary month is delinquent.

Illinois Annual Report Fee: $75

The filing fee is $75, and it is the same amount whether you file online or mail the paper form. The fee schedule for LLC filings sits in the Act at 805 ILCS 180/50-15.

A few related Illinois figures worth budgeting for:

Formation: the official Illinois filing fee for new Articles of Organization is $150.

Registered agent changes: the Statement of Change (Form LLC-1.36/1.37) carries a $25 fee.

Replacement tax: Illinois assesses a 1.5% replacement tax on partnership income for LLCs taxed as partnerships. It is collected through your tax filings rather than through the annual report, but it belongs in the true annual picture for many multi-member LLCs.

What Form LLC-50.1 Reports

The Illinois LLC annual report is Form LLC-50.1. It confirms or updates:

• The LLC's name and state file number
• The principal place of business, which must be a street address but may be located in any state
• The registered agent's name and the Illinois registered office address
• Managers (marked MGR) or, in member-managed companies, the members with management authority (marked MBR), with names and addresses

One thing the annual report cannot do is change your registered agent or registered office. Illinois handles that through a separate Statement of Change, Form LLC-1.36/1.37, with its own $25 fee.

How to File Your Illinois Annual Report

1. Locate your state file number and anniversary month. The file number is required to begin an online filing; you can find both on your original approval documents or by searching the Secretary of State's business records.
2. Review your company information. Confirm the principal address, registered agent, and the list of managers or managing members before you start, since the report must state each of them accurately.
3. File online or by mail. Most LLCs can file through the Secretary of State's online annual report system. Online filing is limited to LLCs with 8 or fewer members; companies with more than 8 members, reports signed under power of attorney, and reinstatement filings must mail the paper Form LLC-50.1 instead.
4. Pay the $75 fee and save your confirmation. Keep proof of filing with your company records in case a bank, lender, or licensing body asks for evidence of good standing.

Late Filing: The $100 Penalty and Dissolution Timeline

Miss the deadline and the consequences arrive on a schedule:

Delinquency: your LLC becomes delinquent on the first day of its anniversary month if the report has not been filed.

Penalty: a $100 late penalty is added beginning on the 60th day past the due date. At that point the filing that would have been $75 becomes $175.

Administrative dissolution: once an LLC has been delinquent for 180 days, the Secretary of State can begin administrative dissolution under 805 ILCS 180/35-25. A dissolved LLC loses its legal standing, and with it the liability protection that justified forming the company in the first place.

Reinstatement: returning from dissolution means paying every missed fee and penalty plus reinstatement charges, a far more expensive path than filing on time.

How We Help

We are not a filing service and we do not submit annual reports on your behalf, but our registered agent service is built to keep this deadline from sneaking up on you.

Compliance reminders: we alert you before your anniversary month arrives so the report can be filed well before the penalty clock starts.

Prompt notification: if the Secretary of State sends a delinquency notice or filing reminder to your registered agent address, we scan and email it to you the day it arrives.

Privacy protection: the annual report lists your registered agent publicly. With our service, our professional address appears in those records instead of your home address.

Staying Compliant in Illinois

Between the $75 fee, the $100 penalty, and a dissolution process that starts at 180 days delinquent, the annual report deserves a permanent place on your company calendar. A reliable registered agent gives that calendar a backstop: reminders ahead of the deadline and same-day delivery of anything the state sends.
