Illinois LLC Annual Report Requirements (and Filing)
The benefits of an operating as an LLC also come with responsibilities. One of these is that every Illinois LLC must file an annual report and pay a filing fee. Many states require this kind of report. Illinois is very strict about it. Failure to file a report by the deadline every year can result in significant penalties for your business. Read on to learn more about the annual report requirements in Illinois.

What is an Annual Report – Recap
If you register an LLC in Illinois, you must file an annual report. This includes LLCs formed under Illinois law and also LLCs from other states that have registered with the Illinois Secretary of State. The Illinois Legislature reduced most of the Secretary of State’s filing fees several years ago from $250 to its current price of $75.
The annual report consists of technical information about the business entity, such as its current legal status, the names of its owners, and its primary business address. The report indicates whether any information has changed since the previous year. It also identifies the individuals or businesses that are responsible for managing the business.
Illinois LLC Annual Report Requirements

You will need the following information in order to prepare an annual report for your LLC:
- LLC business name: This is the official legal name of the business. You do not need to include a DBA or other assumed name.
- Primary business address: You must provide a street address. A P.O. Box is not acceptable.
- Names and addresses of members and/or managers: The annual report should identify the individuals or businesses with the authority to manage the LLC’s operations. This may consist of members, managers, or a combination of both.
- The business purpose and industry: You may need to provide a brief summary of what your LLC does.
- Registered agent contact information: You must provide the name and address of the registered agent. You cannot use the annual report to change the registered agent or registered office. That requires a separate filing.
- LLC EIN number: You might need the employer identification number (EIN) that you obtained from the IRS.
- Your LLC state reference number: You should have received a number from the Illinois Secretary of State when you formed the LLC or registered it as a foreign business entity.
- CEO address and contact information: A person with authority to act on behalf of the LLC, such as a CEO, must sign the annual report.
How to File an Annual Report in Illinois

The due dates and filing requirements for your LLC’s annual reports are very important. Missing a deadline could have serious consequences.
Due dates
The deadline to file an LLC annual report in Illinois is before the first day of the anniversary month of the LLC’s formation or registration. For example, if you filed articles of organization for your LLC on July 15, your annual report would be due on June 30 the following year and each year after that.
You may file an LLC annual report up to 45 days before the due date. The Illinois Secretary of State will not assess a penalty until the 60th day after the due date.
File online
In most cases, you can file your annual report at the online portal. The filing fee is $75, payable by credit card (Visa, MasterCard, Discover, or American Express).
The Secretary of State will void your filing if your credit card company declines the payment. You are responsible for making sure the filing went through.
File by mail
You may also file annual reports by mail. You must file by mail if:
- the LLC has more than eight members or managers;
- one or more managers are not qualified to do business in Illinois;
- you must use layered signatures or a power of attorney to sign the report;
- the state has administratively dissolved or revoked the LLC; or
- the LLC’s legal status has expired.
To file by mail, you can send an original signed Form LLC-50.1 and one copy to the following address:
Secretary of State
Department of Business Services
Limited Liability Division
501 S. Second St., R. 351
Springfield, IL 62756
You may reach the Secretary of State’s office at 217-524-8008, Monday through Friday from 8:00 a.m. to 4:30 p.m. Central time.
Fill in the form with the above information requirements
You will need the information listed earlier in this article. Form LLC-50.1 specifically asks for the following:
- LLC name
- Registered agent and office
- State or country of organization
- Date the LLC was organized or registered in Illinois
- Principal business address — not a P.O. Box
- Names and business addresses of managers and/or members with management authority
- Signature of an individual authorized to act on the LLC’s behalf
File with a compliance service
Rather than filing annual reports yourself, you may use a compliance service. This is among the services that Tailor Brands offers to LLCs. A compliance service can monitor all of your company’s annual compliance requirements. It can provide you with reminders of due dates, obtain all of the necessary information, and handle the filing for you.
What Happens in Case of Late or Missed Filing

Failing to file an annual report as required by Illinois law can have serious repercussions for the LLC. Section 50-15 of the Illinois Limited Liability Company Act identifies the penalties for failure to file.
Late fees and fines
Once an annual report has been overdue for 60 days, the Secretary of State will assess a fine of $100. An additional $100 fine will be added after one year, followed by another $100 each year until the LLC meets its filing obligations.
Penalties
In addition to monetary fines, an LLC that is not in compliance with Illinois annual report filing requirements cannot file any other documents with the Secretary of State. It cannot amend its Articles of Organization, for example, nor can it change its registered agent or registered office. The Secretary of State will not accept any new filings as long as the LLC is out of compliance.
Dissolution
Some states may revoke a business entity’s authorization to do business if it remains out of compliance for too long. This does not dissolve the entity, but it deprives it of the ability to engage in any business activities within the state.
Illinois does not go quite this far, although the effect is similar. Instead, the Secretary of State will show that a non-compliant LLC is not in good standing with the state. A lack of good standing deprives an LLC of many rights and privileges, and could potentially deprive the LLC’s members of liability protection.
Conclusion
Illinois LLCs are obligated to file annual reports, beginning within a year of the date they are formed or registered in the state. An LLC that fails to meet this obligation faces not only monetary fines, but also the possible loss of business privileges. Tailor Brands offers compliance services to LLCs and their owners so that they can focus on running their businesses.
FAQ
The Illinois annual report is a required filing that keeps your LLC’s information like ownership and registered agent details up to date with the Secretary of State. It ensures your business remains in good standing and compliant.
Your annual report is due by the first day of your LLC’s anniversary month each year. For example, if your LLC was formed on July 15, your report is due by July 1 every year.
The filing fee is $75 for LLCs. You can file online, by mail, or in person—but online filing is usually the fastest and easiest method.
If you miss the filing deadline, your LLC may incur late fees and could eventually be administratively dissolved by the state. That means your business would lose its legal standing in Illinois, so it’s crucial to file on time.
