Choosing a name for your organization is the first and most important step in starting your nonprofit corporation. Be sure to choose a name that complies with Illinois naming requirements and is easily searchable by potential members and donors.
To learn more, read our How to Name a Nonprofit in Illinois guide.
1. Follow the naming guidelines:
- The name of your organization must adhere to the following guidelines:
- Must include the letters “NFP” at the end of the name if the name of your organization suggests that the organization was designed for any other purpose than laid out in the nonprofit act.
- Must be distinguishable from other businesses operating in the state of Illinois.
- Unless permission is obtained from the Secretary of State, the name cannot contain terminology related to an established political party.
Read the Illinois General Assembly's official guidelines for the complete rules on naming an Illinois-based organization.
2. Is the name available in Illinois? Make sure the name you want isn't already taken by doing a name search on the State of Illinois Website.
3. Is the URL available? We recommend that you check to see if your business name is available as a web domain. Even if you don't plan to make a business website today, you may want to buy the URL in order to prevent others from acquiring it.
Now that you have verified your name and secured the URL, you can select a professional service to complete the Illinois nonprofit formation process for you. We recommend going with a company with decades of experience and a proven record of customer-focused service:

What is a Registered Agent? A registered agent is an individual or business entity responsible for receiving important legal documents on behalf of your business. Think of your registered agent as your business' point of contact with the state.
Who can be a Registered Agent? A registered agent must be a resident of Illinois or a corporation, such as a registered agent service, authorized to transact business in Illinois. You may elect an individual within the company including yourself.

Step 3: Select your Directors & Officers
The directors of an organization come together to form a board of directors. This board of directors is responsible for overseeing the operations of the nonprofit.
The president, secretary, and other members of nonprofit who have individual responsibilities and authorities are known as officers.
The organization structure of your nonprofit in Illinois MUST include:
- At least 3 directors not related to each other
- A president
- A secretary
NOTE: The president and secretary positions cannot be held by the same person.

Step 4: Adopt Bylaws & Conflict of Interest Policy
To be eligible to apply for 501(c)(3) status, your nonprofit is required to have the following two documents:
- Bylaws
- Conflict of interest policy.
What are Bylaws? Bylaws are the rules outlining the operating procedures of the nonprofit.
What is a Conflict of Interest Policy? A Conflict of Interest Policy is the collection of rules put in place to ensure that any decisions made by the board of directors or the officers benefits the nonprofit and not individual members.
NOTE: The bylaws and conflict of interest policy must be adopted by the nonprofit during its first organizational meeting where the directors and officers are officially appointed.
Step 5: File the Illinois Articles of Incorporation
To register your nonprofit, you will need to file Not-for-profit Articles of Incorporation with the State of Illinois.
To ensure that your nonprofit is eligible to apply for 501(c)(3), in the Articles of Incorporation you must explicitly state the following:
1. Purpose:
In order to qualify for 501(c)(3) status, the organization’s purpose must explicitly be limited to one or more of the following:
