How to File an LLC Annual Report in Illinois (2026)
Illinois charges LLCs $75 to file their annual report. It's due before the first day of your LLC's anniversary month. That's when you first organized in the state. Miss that date and the fees start stacking fast.
The Illinois Secretary of State's Department of Business Services runs this filing. Filing confirms the state has your current registered agent and business address on file.
Quick Summary
- File as soon as the state's reminder arrives. Waiting until the last minute leaves less room to fix mistakes.
- Keep your registered agent address current. That address is where the state sends your annual report reminder every year.
- Put the due date on your own calendar every year. Illinois never rolls the deadline forward.

What Is the Illinois LLC Annual Report
The Illinois LLC annual report is a short filing. It updates the Secretary of State on your registered agent, registered office, business address and manager information.
It's a status filing rather than a tax return, and it keeps your LLC listed as active and in good standing.
Every domestic Illinois LLC must file one annually, and so must every foreign LLC admitted to transact business here. It doesn't matter whether anything has changed since the process to start an LLC in Illinois.
The annual report filing fee is $75, and it applies equally to domestic LLCs and to foreign LLCs admitted to transact business in Illinois.
How to File the Illinois LLC Annual Report
Two filing options are available for the Illinois LLC annual report. File online through the Secretary of State's portal, or file by mail using the paper form.
1. File Online Through the Illinois Secretary of State Portal
Online filing is the faster option for most LLCs. It's free of extra paperwork if nothing on your report needs to change.
- Go to the LLC Annual Report Filings portal and enter your LLC's file number.
- Review the pre-filled information for your registered agent, registered office and managers.
- Confirm there are no changes. The online system won't accept a report that changes your registered agent, office or company name.
- Pay the fee by credit or debit card. A separate payment processor fee applies.
2. File By Mail
Mailing takes longer to process. But it's still your only option whenever the online eligibility rule above doesn't fit your LLC.
- Download Form LLC-50.1 from the Secretary of State's website and fill it out by hand or by typing.
- Make your check or money order payable to the Secretary of State. The office won't accept cash.
- Mail the completed form and payment to the Department of Business Services, Limited Liability Division, 501 S. Second St., Rm. 351, Springfield, IL 62756.
Due Date for the Illinois LLC Annual Report
Your due date ties to your LLC's anniversary month. That's the month your company was first organized or admitted to do business here. The report is due before that month starts, ahead of the actual anniversary date.
Organize on September 15. The deadline falls before September 1 every year after that. The first day of your anniversary month has already passed by the time you organize. That's why your first report isn't due until the anniversary month in the year after formation.
The Secretary of State mails a pre-filled version of your report to your registered agent in Illinois. It arrives within a 60-day mailing lead time ahead of your due date, as a courtesy heads-up.
Filing on time is still your job, even if that reminder never shows up from the state. Don't wait on the mail.
You can also file during the 60-day early-filing window before your due date. There's no reason to wait for the reminder or the deadline.
Penalties, Dissolution and Reinstatement in Illinois
Miss the due date and Illinois doesn't dissolve your LLC right away. You get a 60-day grace period first. After that, a $100 late penalty applies. It grows by another $100 for every extra year you stay delinquent [1].
If the report still isn't filed within 120 days of the due date, the Secretary of State dissolves the LLC administratively [2].
Wait too long and the state steps in further. From that point on, your dissolved LLC can only wind up its business and affairs.
Reinstating a dissolved LLC costs $200, filed on Form LLC-45.70. You'll also owe every annual report fee and penalty that piled up while the company sat delinquent. Budget for the back payments too.
What to Include and How to Update Your Information
Your Illinois LLC annual report must list the company name and the registered agent's name and Illinois address. It also needs your principal place of business address. Add the names and addresses of every manager, plus any member who acts with manager authority.
You can't change your registered agent or office through the annual report itself. File the annual report showing no changes first.
Then change your registered agent in Illinois separately, with Form LLC-1.36/1.37 or the Secretary of State's online change tool. That update costs $25, on top of your annual report fee.
