Entity Name and Address

Having a creative and smart business name is important but not as important as having a legally correct name.


When you choose a name for your business, you have to make sure the name:

  • Meets Illinois naming guidelines
  • Is not already in use by another business in Illinois


Follow the Illinois Naming Guidelines:

  • Your name must include the phrase “limited liability company,” or one of its abbreviations (LLC or L.L.C.). If it is classified as a “low-profit LLC,” it must contain "L3C."
  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • Your name cannot include any of the following terms: Corporation, Corp., Incorporated, Inc., Ltd., Co., Limited Partnership, and L.P.
  • Your name must be the name under which your LLC conducts business unless you register for an assumed name.
  • Your name cannot contain any word or phrase (e.g., trust, trustee, fiduciary) that indicates or implies that your LLC is in the business of a corporate fiduciary unless permitted by the Secretary of Financial and Professional Regulation. If the LLC is organized to accept or execute trusts, the name must contain the word “trust.”
  • The name may not contain any word or phrase that is restricted by any other state statute (e.g., LLCs are not permitted to operate as banks or insurers in Illinois).
  • Your name must be distinguishable from any existing business in the state. This includes Illinois reserved names.

Registered Agent and Registered Office

A registered agent accepts and sends legal documents on your LLC's behalf. When you register your Illinois LLC, you are required to list your registered agent and your registered office. Your registered agent can be anyone 18 years or older that lives in Illinois. It seems simple, but it's important to know that your registered agent must always be available at the registered office during regular business hours.

To learn more about choosing an Illinois registered agent, read our How To Choose an Illinois Registered Agent guide.

To learn more about what a registered agent does and how to choose one, read our What is a Registered Agent guide.

Governing Authority

You must state whether members or managers will manage your LLC. Then, list the information of the managers or members with the authority of manager.

To learn everything you need to know about choosing your management structure, read our Management by Members or Managers guide.

Purpose

In Illinois, you can form a limited liability company for any legal or non-prohibited activity.

Keep in mind that a business purpose that involves licensing, tax-exemption, or tax-deductible status requires specific language from the IRS or a professional license.

Effective Date and Duration

You must list the effective date of the Articles of Organization and the planned dissolution date of the company if it is not perpetual.

Step 3: File the Articles of Organization

To register your LLC, you will need to file the Articles of Organization with the Secretary of State.

Steps After Your Illinois LLC Is Officially Formed

Once you’ve filed your Articles of Organization, you should take the following steps:

Create an Operating Agreement

An LLC operating agreement is a legal document that outlines the ownership structure and member roles of your LLC.

In Illinois, you aren’t required to have an Operating Agreement to officially form an LLC, but it's still a good idea to have one. You can start your operating agreement before, during, or after you file your Articles of Organization.

Your operating agreement will be kept in your LLC’s private business records; you do not file it with the state.

For more information, read our Illinois LLC Operating Agreement guide.

Get an EIN

An Employer Identification Number (EIN) is like a social security number for your LLC. You will need an EIN if you want to hire employees or open business bank accounts.

You can get your EIN for free through the IRS website, via fax, or by mail. If you would like to learn more about EINs and how they can benefit your LLC, read our What is an EIN article.

Open a Business Bank Account

Using dedicated business banking and credit accounts is essential to protect your business' corporate veil. When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your LLC is sued.

Get Licenses and Permits

When you are registering an LLC, you need to determine if your business needs any licenses or permits in order to remain compliant. On the federal level, there are a handful of business activities that require licenses and/or permits.
