In Illinois, your limited liability company (LLC) is not required to have an operating agreement in place. But it’s highly recommended, as an effective operating agreement can help avoid disputes and lawsuits that could threaten the stability of your LLC. 

What is an LLC Operating Agreement?

An Illinois LLC operating agreement is an important legal document that details who owns the business and provides essential information pertaining to member duties. An LLC operating agreement establishes the financial relationship between members and the basics of the working relationships between those members and the managers who oversee daily operations. 

The operating agreement is not filed with the state of Illinois, but instead remains private. It’s advisable to hire an attorney to ensure your operating agreement is thorough and legally binding.


We’ve provided two operating agreement templates for your use. One is for a single-member LLC if you are the sole member, and the other is for a multi-member LLC if your LLC has two or more members. The documents are customizable and should be adjusted for Illinois state and your business. These documents are for your internal use and are not filed with any governing body.

These documents should not be considered legal advice. You should have your version of the document reviewed by your attorney to make sure that all necessary provisions are included to fit your business situation.

An LLC operating agreement provides legal and financial recourse for a number of situations. If conflicts arise between LLC owners pertaining to any of the above issues, the operating agreement will provide clarity. The specific language of the operating agreement lays out exactly how such conflicts will be resolved, how the business is structured, the dynamics of operations, and more. 

Though Illinois has default rules on the books that address some of the issues that might arise between LLC members, your LLC operating agreement would override these default laws and give you greater control. Remember to consult with an attorney to ensure that your operating agreement is legally sound and adequately addresses your business needs.

How Much Does an Operating Agreement Cost? 

Creating an operating agreement is free if you just draw it up yourself. Alternatively, you can pay for guidance from an online business advisory like ZenBusiness.

This is an extremely important document, so it’s recommended that you hire a professional service or law firm. If you choose to use an attorney to help you create this document, the price will be around $500 for a single-member LLC and $2,500 for a multi-member LLC

Who Needs my LLC Operating Agreement?

One of the key reasons to have an operating agreement in place is that it makes your LLC more appealing to financial backers. Banks are likely to request to see your operating agreement when you apply for a loan. If you seek funding from investors, they will also want to see your operating agreement. 


Though not legally required in Illinois, an operating agreement is a crucial document for LLC operations, ensuring your company is able to access adequate financing and settle any disputes. Keep in mind, you do not need to file your operating agreement with any state body. You simply need to take certain steps to ensure it’s legally binding and keep it in your records.
