What Is an Illinois LLC Operating Agreement?

An Illinois LLC operating agreement is a legal document outlining your company’s internal structure, ownership, and management.

Even though it isn’t required by state law, having an agreement in place ensures your business is recognized as a separate entity, helps prevent disputes, and strengthens your credibility with lenders and partners. Without one, your LLC could be treated as a sole proprietorship or general partnership for tax or legal purposes.

Laws, Costs, and Fees in Illinois

LLC operating agreements in Illinois are governed by the Limited Liability Company Act (805 ILCS 180/), which covers formation, operation, and member rights.
Key sections include:

LLC Formation Costs in Illinois:

  • Articles of organization filing fee: $150 ($400 for a series LLC).
  • Name reservation fee: $25.
  • Annual report fee: $75.

Additional fees apply for expedited services

How to Create an Illinois LLC Operating Agreement

Follow these steps to start your LLC and draft your operating agreement in Illinois:

  1. Find a registered agent: Illinois requires all LLCs to appoint a registered agent—a person or entity responsible for receiving legal documents. The agent must have a physical street address in Illinois and can be either a state resident or a business authorized to operate in Illinois.
  2. File your registration documents: Choose between forming a domestic or foreign LLC. Print and complete your registration forms (two copies recommended), then submit them to the Illinois Secretary of State. Foreign LLCs must also include a certificate of existence issued within the last 60 days and signed by a company officer. You can file either by mail or online.
  3. Pay your filing fee: Pay your filing fee to finalize your LLC registration. You can pay online for a discount or send a paper check or money order to the Secretary of State’s office.
  4. Set up your operating agreement: Though optional, an operating agreement is highly recommended to protect your company and maintain consistent internal structure. It defines ownership interests, profit distribution, and management responsibilities, ensuring compliance and stability.
  5. Get an Employer Identification Number (EIN): Apply for an EIN through the IRS website. This nine-digit number identifies your business for tax purposes and allows you to hire employees, open bank accounts, or apply for financing.
