Incorporating in Illinois

Illinois has certain incorporation standards that are good to know about when you incorporate in Illinois. These include corporate director requirements, standards for your corporation’s name, the information in your Articles of Incorporation when you incorporate, and more.

Naming Your Illinois Corporation

When you incorporate in Illinois, your business name needs to include one of the following:

  • "Corporation"
  • "Limited"
  • "Company"
  • "Incorporated"
  • ""an abbreviation of one of the words listed above

Other standards apply as well. For example, words such as “Bank” or “Trust” require approval from the appropriate department. The corporate name can’t imply or indicate that your corporation is organized to conduct the business of banking, indemnity, acceptance of savings deposit, corporate fiduciary, assurance or insurance.

With respect to similarity of names, the name generally needs to be distinguishable from any domestic or authorized foreign corporation and from a name to which exclusive right is registered or reserved. Often, the state may not approve the use of dashes in the corporate name.
