Illinois LLC Annual Report: Filing Guide, Fees & Deadlines (2026)

If you’re running an LLC in Illinois, mark your calendar: your annual report is due before the first day of your LLC’s anniversary month, with a $75 filing fee payable to the Illinois Secretary of State. Missing this crucial compliance deadline can result in penalties and even administrative dissolution of your business, making it essential to understand exactly what’s required and when.

What Is the Illinois LLC Annual Report?

The Illinois LLC Annual Report is a mandatory filing that all active limited liability companies must submit to the Illinois Secretary of State each year. This report serves as an official confirmation of your LLC’s current information, including its principal office address and manager or member names. A change of registered agent or registered office is not made on the annual report — it is filed separately, online or on Form LLC-1.36/1.37. The requirement stems from the Illinois Limited Liability Company Act (805 ILCS 180), which mandates that LLCs maintain accurate records with the state to remain in good standing.

Every Illinois LLC, regardless of size or business activity, must file this annual report. This includes single-member LLCs, multi-member LLCs, domestic LLCs formed in Illinois, and foreign LLCs authorized to do business in the state. Even if your LLC had no business activity during the year or your information hasn’t changed, you’re still required to file the report and pay the associated fee.

The annual report isn’t just a bureaucratic formality—it’s a critical compliance requirement that keeps your LLC’s legal protections intact. By maintaining current information with the Secretary of State, you ensure that official notices reach the right people, maintain your limited liability protection, and preserve your ability to conduct business legally in Illinois.

When Is the Illinois LLC Annual Report Due?

Illinois LLCs must file their annual report before the first day of their anniversary month each year; the report, together with all fees and charges, has to be delivered to the Secretary of State within the 60 days immediately preceding that day. Your anniversary month is the month in which your LLC was originally formed or, for foreign LLCs, the month you were authorized to do business in Illinois. For example, if you formed your LLC on March 15, 2025, your annual report would be due before March 1, 2026, and before March 1 in each year after that — a report filed on March 1 itself is already delinquent.

First-year LLCs get a bit of breathing room. If your LLC was formed within the 60 days before the first day of your anniversary month, your first annual report isn’t due until the following year. This grace period prevents brand-new LLCs from having to file an annual report immediately after formation.

The Illinois Secretary of State sends a pre-filled version of the annual report to your registered agent approximately 45 days before the due date. However, receiving this notice isn’t a requirement for filing—you’re responsible for filing on time whether you receive a reminder or not. Many LLC owners set calendar reminders or work with registered agents who track these deadlines to ensure compliance.

It’s worth noting that Illinois allows you to file your annual report up to 60 days before the due date. This early filing option can be particularly helpful for busy business owners who want to handle compliance matters ahead of time or those who prefer to batch their administrative tasks.

How Much Does the Illinois LLC Annual Report Cost?

The Illinois LLC Annual Report filing fee is $75 for 2026, payable to the Illinois Secretary of State. The fee is the same whether your LLC has been in business for one year or twenty years, but online filing costs a little more than $75: a payment processor fee is assessed on all online transactions. The fee must be paid at the time of filing — online the Secretary of State accepts credit and debit cards (Visa, Mastercard, Discover or American Express), while mail submissions are paid by check.

If you miss your filing deadline, Illinois imposes a late-filing penalty of $100 in addition to the regular $75 filing fee, bringing your total cost to $175. The penalty is not charged the moment the due date passes: it applies if the annual report is not filed within 60 days after the due date, that is, not before the first day of the second month after the anniversary month. If the delinquency continues, a further $100 is added for each year or fraction of a year beginning with the second year of delinquency, until the LLC is returned to good standing or reinstatement is effected.

For LLCs that fail to file for an extended period and face administrative dissolution, the reinstatement process becomes significantly more expensive. Reinstating a dissolved Illinois LLC requires filing all missed annual reports, paying all associated fees and penalties, plus a reinstatement fee of $200. For a business that’s been dissolved for multiple years, these costs can quickly add up to several hundred dollars or more.

Some Illinois LLCs may also need to pay additional fees for related services. For instance, if you need to update your registered agent or make other changes to your LLC’s information outside of the annual report, separate amendment fees may apply. Expedited handling of a paper annual report (Form LLC-50.1) costs an extra $50. There is no expedited fee for filing online, because online annual reports are processed in real time.

How to File Your Illinois LLC Annual Report: Step-by-Step

Step 1: Gather Your LLC Information

Before starting your annual report, collect all necessary information about your LLC. You’ll need your Illinois File Number (found on your LLC formation documents), current registered agent name and address, principal business address, and names and addresses of all managers or members. Having this information ready streamlines the filing process and helps prevent errors that could delay processing.

Step 2: Access the Illinois Secretary of State Website

Navigate to the Illinois Secretary of State’s business services portal at ilsos.gov. Look for the “File an Annual Report” option under the Business Services section. The online filing system is available 24/7, making it convenient to file at any time. You can also request paper forms if you prefer to file by mail, though online filing is generally faster and provides immediate confirmation.

Step 3: Search for Your LLC

Use the business entity search function to locate your LLC in the state database. You can search by LLC name or file number. Once you find your business, verify that the displayed information matches your records. If you notice any discrepancies, you may need to file amendments before or along with your annual report.

Step 4: Complete the Annual Report Form

The online annual report form will pre-populate with your LLC’s information from the previous year. Review each field carefully and update any information that has changed, such as the principal office address or manager and member details. The registered agent and registered office are not changed here: if you need to change either one, you file the annual report indicating no changes and then change the registered agent or registered office online or on Form LLC-1.36/1.37. You also can’t file the annual report online at all if the name of the registered agent or the address of the registered office is changing. Even if nothing has changed, you must still file the report to confirm that your information remains current.

Step 5: Pay the Filing Fee

After reviewing and submitting your annual report information, you’ll be directed to the payment page. The $75 filing fee is paid online by credit or debit card — Visa, Mastercard, Discover or American Express — and a payment processor fee is assessed on every online transaction. The system will process your payment immediately and provide a confirmation number for your records.

Step 6: Save Your Confirmation

Once your filing is complete, save or print the confirmation page showing your submission details and confirmation number. This serves as proof of filing and should be kept with your LLC’s important documents. If filing by mail, make a copy of your completed form and payment for your records before sending it to the Secretary of State.

What Happens If You Don’t File?

Failing to file your Illinois LLC Annual Report triggers a series of increasingly serious consequences. A $100 late-filing penalty is added to your filing fee once the report has not been filed within 60 days after the due date. Your LLC does not stay in good standing in the meantime: the Secretary of State declares a limited liability company delinquent and not in good standing as soon as it has failed to file its annual report and pay the requisite fee before the first day of the anniversary month in the year in which it is due. The Illinois Secretary of State will typically send a notice of delinquency, though as with the initial reminder, you’re responsible for filing whether you receive this notice or not.

If your annual report remains unfiled for an extended period (typically several months), the Secretary of State will begin administrative dissolution proceedings. This process starts with a notice of delinquency; if the LLC does not correct the default within 120 days following the date of that notice, the Secretary of State dissolves the LLC by issuing a certificate of dissolution that recites the grounds for dissolution and its effective date. Administrative dissolution means your LLC loses its legal status and the protections that come with it.

Once administratively dissolved, your LLC can no longer legally conduct business in Illinois. This means you can’t enter into contracts, maintain lawsuits, or operate under your LLC name. Perhaps most critically, dissolution can compromise the limited liability protection that shields your personal assets from business debts and lawsuits. Banks may freeze business accounts, and you may lose the right to your LLC’s name if another business claims it.

Reinstatement after administrative dissolution requires filing all delinquent annual reports, paying all associated fees and late penalties, plus a $200 reinstatement fee. The reinstatement application must include a statement that all required reports are being filed and all fees paid. Once reinstated, your LLC is restored to good standing retroactively, as if the dissolution never occurred, though the gap in good standing could still affect business relationships and credit.

Frequently Asked Questions

Can I file my Illinois LLC Annual Report early?

Yes, Illinois allows LLCs to file their annual report up to 60 days before the due date. This early filing option helps business owners manage their compliance obligations proactively. Filing early doesn’t change your next year’s due date—the report will still be due before the first day of your anniversary month. Many LLC owners choose to file early to avoid the risk of missing deadlines during busy periods or while traveling.

What information can I update in my annual report?

The Illinois LLC Annual Report lets you update your principal office address and the names and addresses of managers or members. It is not how you change your registered agent or registered office: for that you file the annual report indicating no changes, then change the registered agent or registered office online or on Form LLC-1.36/1.37. However, you cannot change your LLC’s name or add/remove members through the annual report—these changes require separate amendment filings. If you need to make substantial changes to your LLC’s structure or operating agreement, consult with a business attorney about the appropriate filing procedures.

Do I need to file an annual report if my Illinois LLC had no activity?

Yes, all active Illinois LLCs must file annual reports regardless of business activity level. Even if your LLC had no revenue, conducted no business, or maintained no bank accounts during the year, you’re still required to file the annual report and pay the $75 fee. The only way to avoid this requirement is to formally dissolve your LLC with the Secretary of State, which involves a separate dissolution filing and fee.

How do I know if my Illinois LLC Annual Report was accepted?

When filing online, you’ll receive an immediate confirmation number and can print a confirmation page upon successful submission. Annual reports filed online are processed by the Illinois Secretary of State in real time. You can verify your filing status by searching for your LLC on the Secretary of State’s website and checking that your status shows as “Active” and in good standing. If filing by mail, processing may take 10-15 business days.

Can someone else file my LLC’s annual report for me?

Yes, anyone with the necessary LLC information can file your annual report. This includes registered agents, attorneys, accountants, or other authorized representatives. Many registered agent services include annual report filing as part of their service package. However, regardless of who files the report, the LLC’s managers or members remain ultimately responsible for ensuring timely and accurate filing.

Bottom Line

The Illinois LLC Annual Report is a straightforward but critical compliance requirement that keeps your business in good standing with the state. With a reasonable $75 fee and the convenience of online filing, there’s no reason to risk the penalties and complications that come with missing this deadline. Set up reminders so the report is filed before the first day of your anniversary month, keep your LLC information current throughout the year, and take advantage of the 60-day early filing window to stay ahead of your compliance obligations.

Remember that maintaining good standing isn’t just about avoiding penalties—it’s about protecting the limited liability shield that makes the LLC structure valuable in the first place. Whether you handle the filing yourself or work with a professional service, make your Illinois LLC Annual Report a priority each year. The few minutes it takes to file online are a small investment in maintaining your business’s legal protections and operational freedom.
