Starting Your Illinois LLC

Although it may seem complicated, the process to start an LLC in Illinois is much less difficult than you think — especially when you have experienced help. The first phase for Illinois LLC formation includes the following steps:

Step 1: Name Your Illinois LLC

The first step for your Illinois LLC is to name your business. The state does have some regulations and restrictions concerning business names—see below:

Tip: Use a free business name search tool to ensure your company’s desired name is available. If the name is unavailable, try a free business name generator to help ideate alternative names.

Business Name Guidelines

  • The official name of your business must end with: Limited Liability Company, Limited Company, LLC, or L.L.C.
  • Your business name cannot be intentionally misleading to consumers
  • The name of your new LLC must not be similar to another organization’s name/trademark

There are some state and federal level restrictions concerning certain words that cannot be used for a business name.

A few examples include:

  • “Lottery” and “Bank” are ineligible for use (any state)
  • Terms that represent educational or Veterans’ organizations are restricted
  • Terms related to the Armed Forces or civil servants (police, EMT, fire)

LLC business names associated with government and/or financial entities are not always restricted—it depends on the state. Additional paperwork may be required.

URL Availability
As you are deciding on a business name, you also need to choose a domain name for your company’s website. Especially in this culture, it is important that your Illinois LLC have an online presence even if you are not doing business online.

Step 2: Establish Ownership

LLC owners are known as members or managers; the difference in title depends on the selected management structure of the LLC.

LLC Management Structures:

  • Member-managed: All members share in the decisions and daily operations of the LLC
  • Manager-managed: A manager runs the business; the members are not involved most decisions for the LLC.   

Illinois LLC Member Guidelines:

Required Number of Members
Illinois LLCs must have at least one member or manager in order to form a business.

Member Disclosure Requirements
Illinois state law requires all LLC members/manager to be listed in the Articles of Organization.

Age Restrictions
LLC members in Illinois may be of any age.

Residence Restrictions
There are no residency restrictions imposed on LLC members in Illinois.

Step 3: Find a Registered Agent in Illinois

In order to start an LLC in Illinois, you will need to appoint a registered agent. This position is required for any Illinois business to legally operate.

What is a registered agent?
A registered agent is an authorized party (person or business) who receives all official state and legal notices on behalf of the LLC.

Why do you need a registered agent?
The state of Illinois requires all business to have an appointed registered agent; this party serves as the consistent contact person between the LLC and the Secretary of State.

What are the main requirements for a registered agent?
There are 2 main requirements: 1) The registered agent must have a physical address — not a P.O. Box, and 2) The registered agent must be available during business hours.

Who can be a registered agent in Ilinois?
Either an Illinois resident with a physical address can be a registered agent in Illinois, or an Illinois LLC or corporation licensed to work in Illinois.

Can I be my own registered agent for my business?
You can appoint yourself as your LLC’s registered agent as long as you fit the guidelines.

Is being my own registered agent discouraged?
LLC business owners who choose to be their own registered agent risk compromising their personal information since the registered agent’s name and address must be publicly listed.

  • The location of the business
  • The contact information of all members/managers
  • The name and location of the registered agent

A few points to consider:

  • The members are still subject to whichever licensing boards govern the LLC’s profession.

An LLC Operating Agreement may be not required by the state, but it is still necessary for the successful formation of your Illinois LLC.

The LLC Operating Agreement is necessary because it adds structure to the business by defining the roles of the members and explaining the purpose and function of the LLC. It also helps in reducing disputes among the members by ensuring a level of stability and transparency.

Do I need to file the LLC Operating Agreement?
You do not need to file the Operating Agreement with the state; it is for the benefit of your LLC and remains in-house.

What goes into an LLC Operating Agreement?
Every LLC Operating Agreement is unique to the business; however, most agreements include the following:

  • Designation of the members/managers
  • Initial capital contributions of the members
  • Voting designations and percentages
  • Member transfer/addition rules and restrictions
  • Distribution of profits

What business entities need an EIN?
The types of business entities that need an EIN include:

  • An LLC with employees (even if owned by one person)
  • An LLC with more than one member
  • A partnership (LLC or C-corp)

Please Note: A sole proprietorship is not required to have an EIN.

Why is an EIN necessary?
The more common reasons you would need an EIN are:

  • To hire employees
  • To open a bank account in the U.S.
  • To file your company’s taxes
  • To pay independent contractors

Please Note: If your business brings in revenue of any kind, you need an EIN.
