Illinois LLC Annual Report 2026: $75 Fee, $100 Late Penalty

Due Date and Frequency

The Annual Report is an annual obligation — filed once per year. There is no biennial option in Illinois. Every LLC, regardless of size, revenue, or activity level, must file every year to maintain good standing.

The Secretary of State typically sends reminder notices to the registered agent's address and/or email on file. However, receipt of a reminder is not a prerequisite for the filing obligation. It is your LLC's responsibility to file on time regardless of whether a reminder is received. Because the deadline is tied to your formation month, mark your anniversary month on your business calendar so it does not slip.

Annual Report Fee: $75

Illinois charges a flat annual report fee for LLCs:

Illinois's $75 annual report fee is in the mid-to-higher range among Midwest states. Compare to Wisconsin ($25 for domestic LLCs), Iowa ($30), or Indiana (a $50 business entity report filed biennially). The fee itself is manageable — the real cost in Illinois comes from filing late, covered below, so the goal is always to file on time.

Fee, deadline, and penalty figures on this page are read from the Illinois Secretary of State's own LLC annual report instructions at ilsos.gov, verified September 14, 2026. This is general information, not legal or tax advice — always confirm current figures at ilsos.gov before you file or pay.

What Information Is Required

The Illinois Annual Report requires you to confirm or update the following information:

• Registered Agent: The name and physical Illinois street address of your registered agent. If your agent has changed or their address has changed, update it here.
• Principal Office Address: The main business address of your LLC. This must be a physical address, not a PO Box.
• Member or Manager Details: For member-managed LLCs, the members. For manager-managed LLCs, the managers. Include names and addresses as required by the form.
• Effective Date of Changes (if any): If you are reporting changes to registered agent, address, or management since last year, note when those changes took effect.

You are not required to submit financial statements, revenue figures, tax information, employee counts, or details about your business operations. The Annual Report is purely an administrative confirmation and update filing.

Step-by-Step: How to File the Annual Report Online

Filing your Illinois LLC Annual Report online is the fastest method. Here is the step-by-step process:

1. Go directly to the filing portal
   File at apps.ilsos.gov/llcarpt, the Illinois Secretary of State's LLC Annual Report Filings portal (linked from the ilsos.gov annual report instructions page). That is the actual filing system — bookmark it so you are not hunting for it again next year.
2. Look up your LLC
   Enter your LLC's name or file number to find your entity. Select your LLC from the results and confirm this is your entity before proceeding.
3. Select "File Annual Report"
   On your LLC's page, choose the option to file the Annual Report. The system will pre-populate your current information from Secretary of State records.
4. Review and update your information
   Confirm or update: registered agent name and address, principal office address, and member/manager details. Make any necessary corrections before proceeding.
5. Submit and pay the $75 fee
   Review your information one final time, then pay the $75 fee by credit or debit card. Make sure you file before the first day of your anniversary month to avoid the late penalty.
6. Save your confirmation
   After payment, you will receive confirmation that your Annual Report was accepted. Save this confirmation as proof of filing. The Secretary of State will update your LLC's status to reflect the current year's filing.

What Happens If You Miss the Deadline

Illinois used to have one of the steepest late penalties in the country. That changed: HB 4578 (805 ILCS 180/50-15) replaced the old $300-plus-$100/month structure with a flat, one-time penalty. Here is what actually applies now:

Because penalty amounts can change, always confirm the current late penalties at ilsos.govbefore filing late so you know exactly what you owe. The simplest protection is to never get there: set a calendar reminder a few weeks before your anniversary month each year so you file before the deadline and owe nothing but the $75 fee. This is general information, not legal advice.

How to Reinstate a Dissolved LLC in Illinois

If your Illinois LLC has been administratively dissolved for missed annual reports, reinstatement is possible. Here is the general process:

1. File all overdue Annual Reports
   You must bring all missed Annual Reports current and pay all overdue fees and penalties — every missed $75 report, plus the flat $100 penalty and the additional $100 for each further delinquent year.
2. File Form LLC-35.40 and pay the $200 reinstatement fee
   Submit the Application for Reinstatement (Form LLC-35.40) to the Illinois Secretary of State and pay the $200 reinstatement fee. For one missed year that is roughly $375 total: $200 reinstatement + $75 report + $100 penalty. Confirm the current fee schedule and requirements at ilsos.gov, as costs can change.
3. Confirm your registered agent is current
   Ensure your registered agent information is accurate and up to date at the time of reinstatement filing.
4. Await Secretary of State approval
   The Secretary of State will review your reinstatement and, if all overdue fees and penalties are paid and all requirements are met, restore your LLC to good standing. You will receive confirmation of reinstatement.

Note that during the period of dissolution, your LLC could not legally enter contracts or sue in Illinois courts. Any contracts entered during the dissolved period may be voidable. If significant business was conducted during dissolution, consult an Illinois business attorney about potential exposure.

Staying compliant is far cheaper than reinstating. See the annual report deadlines for every state  and our Illinois business compliance hub  for the full picture.
