Illinois Annual Report Filing Guide 2026: Deadlines, Fees & How to File | FileForms

For business owners, accountants, lawyers & multi-entity managers

Every LLC, corporation, and other registered entity in Illinois must file an Annual Report with the Illinois Secretary of State each year to remain active and in good standing. Illinois uses an anniversary-based deadline system — every entity’s due date is tied to its formation month — making year-round compliance monitoring essential, especially for multi-entity operators.

This guide explains exactly what Illinois requires, what it costs, how deadlines work, and how FileForms can automate your Illinois filings to eliminate missed deadlines and manual tracking across your entire portfolio.

Why Illinois Annual Report Filing Is Essential

Every active Illinois entity must file an annual report with the Secretary of State. This filing:

• Keeps your entity in Good Standing with the state
• Confirms current officer, manager, member, and address information
• Prevents administrative dissolution and loss of limited liability protections
• Enables issuance of a Certificate of Good Standing for financing, contracts, and licensing
• Is the basis for calculating Illinois franchise tax for corporations

Failure to file can result in late fees, loss of good standing, administrative dissolution, and — for corporations — significant franchise tax penalties.

Illinois Annual Report Deadline: Before the First Day of Your Anniversary Month

Illinois uses an anniversary-based deadline — your annual report is due before the first day of the month in which your entity was originally formed. In practical terms, this means by the last day of the month prior to your anniversary month.

How to Calculate Your Deadline

• Entity formed in June → annual report due by May 31
• Entity formed in January → annual report due by December 31 of the prior year
• Entity formed in October → annual report due by September 30

45-Day Early Filing Window

Illinois allows you to file up to 45 days before your due date. The Illinois Secretary of State mails a pre-filled annual report form to your registered agent approximately 45 days before the due date as a reminder — but it is your responsibility to file on time regardless of whether you receive this notice.

First-Year Filing Rule

New Illinois entities are not required to file in their formation year. The first annual report is due in the year following formation, before the first day of the anniversary month. For example, an LLC formed in June 2026 first files by May 31, 2027.

Illinois Annual Report Filing Fees

LLC Filing Fee: $75

All Illinois LLCs — domestic and foreign — pay a $75 annual report filing fee. This fee applies whether you file online or by mail.

Corporation Filing Fee: $75 + Franchise Tax

Illinois corporations pay a $75 filing fee plus an Illinois franchise tax calculated on paid-in capital. The franchise tax is a separate calculation included in the annual report and must be paid at the same time. Recent legislative changes have created exemptions for some businesses — verify current requirements on the Illinois Secretary of State website. LLCs are not subject to the Illinois franchise tax.

Limited Partnership: $100

Limited partnerships pay a $100 annual report fee.

Nonprofit Corporation: $10–$15

Nonprofit corporations pay a $10–$15 annual report fee depending on entity type.

LLP: No Annual Report Fee

Limited liability partnerships in Illinois do not have an annual report filing requirement.

Late Penalties and Dissolution Timelines

LLCs

• $100 late penalty assessed once the deadline is missed (reduced from $300 under House Bill 4578)
• After 60 days past due: notice issued that the LLC must file within another 60 days or face administrative dissolution
• After the second 60-day window without filing: administrative dissolution
• Reinstatement: file an Application for Reinstatement plus all outstanding fees

Corporations

• After 30 days: notice of delinquency issued
• After another 90 days without filing: administrative dissolution
• $300 late penalty applies after 60 days overdue, plus additional franchise tax penalties
• Reinstatement: file a Corporation Application for Reinstatement plus a $200 reinstatement fee and all outstanding fees

Nonprofits

• Revocation occurs 6 months after the annual report was due
• Reinstatement: file a Nonprofit Application for Reinstatement plus a $25 reinstatement fee and all outstanding fees

Important Illinois-Specific Rules to Know

Registered Agent Changes Require a Separate Filing

You cannot change your registered agent as part of the online annual report. Registered agent and registered office changes require a separate Statement of Change of Registered Agent and/or Registered Office (Form BCA 5.10/5.20 for corporations) with its own fee.

LLCs With More Than 8 Members Must File by Mail

Online annual report filing is limited to LLCs with 8 or fewer members (up to 6 officers and 6 directors can be entered electronically). LLCs with more than 8 members, entities using power of attorney signatures, and those undergoing reinstatement must file by mail using Form LLC-50.1.

No Extensions Granted

Illinois does not grant extensions for annual report filings. Filing early — within the 45-day window — is strongly recommended to avoid last-minute technical issues or payment problems.

How to File an Illinois Annual Report

Illinois accepts online filing through the Secretary of State Business Services portal (recommended) or by mail. Online filings are processed immediately; mail filings take 10–15 business days.

1. Find your Illinois file number — locate it on your Articles of Organization or by searching your entity in the Illinois Business Entity Search at ilsos.gov
2. Go to ilsos.gov Business Services — select your entity type and click the Annual Report filing link
3. Enter your file number — the system retrieves your pre-filled report with current information on file. Note: LLCs with more than 8 members must use Form LLC-50.1 by mail
4. Review and update your information — confirm or update principal business address (no P.O. boxes), names and addresses of members/managers (LLCs) or officers/directors (corporations), and CEO contact information. Note: registered agent changes require a separate form
5. Calculate franchise tax (corporations only) — complete the franchise tax section based on paid-in capital
6. Pay and submit — LLCs pay $75; corporations pay $75 plus franchise tax. Online payment by Visa, MasterCard, Discover, or American Express. Mail filers send a check payable to the Secretary of State to: Illinois Secretary of State, Department of Business Services, 501 S. Second St., Rm. 350, Springfield, IL 62756
7. Save your confirmation — online filings receive immediate confirmation; print and save. Mail filers: include two copies and a self-addressed stamped envelope to receive an approved copy back

Why Illinois Annual Reports Are Hard to Manage at Scale

1. Every Entity Has a Different Deadline

With anniversary-based deadlines, a portfolio of Illinois entities formed across different months means different due dates throughout the year. There is no single “Illinois filing season” to anchor compliance efforts.

2. Corporations Have Two Separate Payment Obligations

Illinois corporations must track both the $75 filing fee and the franchise tax calculation — two separate obligations filed together but requiring different calculations. For multi-entity portfolios with mixed LLC and corporation holdings, the compliance workflows diverge significantly.

3. The LLC Late Penalty Structure Changed

The LLC late penalty was recently reduced from $300 to $100 under House Bill 4578 — but many online resources still cite the old amount. Knowing the current $100 figure matters for accurate budgeting and risk assessment.

4. Mail-Only Filing for Large LLCs

LLCs with more than 8 members cannot use the online portal — they must file by mail, adding 10–15 business day processing time. For portfolios with large multi-member LLCs, this creates a tighter effective deadline than the online filers have.

5. Registered Agent Changes Are a Separate Process

Unlike many states where registered agent updates can be made on the annual report, Illinois requires a separate form. If your team conflates the two processes, the registered agent change may never get filed.
