How To Fill Single-Member LLC Operating Agreement for an Illinois-based Company

An Illinois single-member LLC operating agreement is a legal document for a sole proprietor to establish ownership, policies, and procedures. Although not required by the state, this document protects the owner's assets from business debts and offers tax benefits. Without it, the owner's private finances are at risk, and certain tax advantages won't be available.

Company Name

Enter your LLC's name, ensuring it complies with Illinois naming guidelines. For example, if you own a vintage furniture store, you might name it "Timeless Treasures Emporium, LLC."

Company and Member Information

Fill in the date you sign the agreement to indicate when it becomes effective. For instance, you could enter "June 10, 2023." Write also the full name of the LLC and also of the sole member of the LLC to show who owns the company and is responsible for its operations, such as "Aiden Montgomery."

Formation Date

Enter first the full legal name of your LLC. In the next space enter the date the Articles of Organization were filed with the state of Illinois. This confirms your LLC's legal establishment. For example, you could enter "May 15, 2023."


In the "Purposes and Powers" section, describe your LLC's primary purpose or business activities. This outlines your company's scope of operations. For instance, if your LLC specializes in restoring vintage furniture, you might write, "To restore and sell vintage furniture in Illinois."


Write the sole member's name in the Authority section, such as "Aiden Montgomery." This emphasizes their power to make decisions and act on behalf of the LLC.

Signature and Printed Name

At the end of the document, sign your name on the "Managing Member's Signature" line and print it below. This shows your acceptance of the terms and commitment to follow the operating agreement. For example, sign and print "Aiden Montgomery."

In conclusion, the process of filling out a single-member LLC operating agreement for an Illinois-based company involves providing essential information such as the company name, formation date, purpose, and authority. By completing this document, the sole proprietor can ensure asset protection and secure tax advantages. It is crucial for the owner to follow these guidelines and complete the operating agreement accurately in order to enjoy its benefits and prevent potential legal or financial issues. Ultimately, the single-member LLC operating agreement serves as a foundation for establishing a well-organized and legally compliant business structure in the state of Illinois.
