If you are forming an LLC in Illinois, then this page’s content would be vital. As you learn how to start an LLC, you will realize that the bulk of your initial work and LLC cost comprises filing an Illinois article of organization, which we will elaborate on this page.   

What is an Article of Organization?

An Article of Organization, also known as an LLC certificate or Certificate of Formation in some states, is a document filed with the secretary of state to form an LLC.

Each state has a different requirement to fill out a form. An Article of Formation usually includes the following:

  • The name of the LLC,
  • the effective date of the LLC,
  • the company’s principal office,
  • the business purpose,
  • the duration of the business, 
  • a copy of the LLC’s name registration certificate, and
  • the name and address of the registered agent, organizers, and
  • at least one member of the company.

You can file an Article of Organization online, by mail, or in person.

Note that the certification of formation is a legal requirement, not to mention, the core of your LLC formation. It even makes up the bulk of your Illinois LLC cost. Without it, you have no LLC. So, take the time to complete and file this certificate.
