Choose a Corporate Structure
Incorporating means starting a corporation. If you want to form an LLC, please see "How to Form an LLC in Illinois".
Is your corporation for-profit or not-for-profit? If you are starting a nonprofit, please see "How to Start a Non-Profit Organization in Illinois".
C-Corp and S-Corp refer to taxation with the IRS, not to legal structures. Your corporation is taxed as a C-Corp unless you file an election to be taxed as an S-Corp (explained below).
Check Name Availability
The legal name of your corporation may not conflict with any other registered name. Check availability of your desired name by conducting a name search.
Name Search: Name Reservation: Optional Suffix Requirements:
Shall contain, separate and apart from any other word or abbreviation in such name, the word "corporation", "company", "incorporated", or "limited", or an abbreviation of one of such words.
805 ILCS §5/4.05
Appoint a Registered Agent
Before you officially file to create your Illinois LLC, you will need to decide who your Illinois registered agent will be. A registered agent is a business's legal appointee to receive notice of lawsuit and other legal or government notices.
State law requires every LLC to have a registered agent. The registered agent is designated when you file Illinois articles of organization with the Illinois Secretary of State - Business Services Department.
Our reliable registered agent service fulfills this requirement. You get:
- Same-day documents from our local office in Springfield
- Immediate online access to state forms with our address and, where required, our signature
- Annual fees from $89 to $99 per state with no additional charges

Establish Bylaws & Corporate Records
Your corporation must keep correct and complete books and records.
Draft bylaws (potentially using a template) which is the governing document for the corporation. The bylaws of a corporation may contain any provision for managing the business and regulating the affairs of the corporation that is not inconsistent with law or with the articles of incorporation (C.R.S. 7-102-106). You will review and ratify the bylaws at your first board of directors meeting.
A corporation shall keep as permanent records minutes of all meetings of its shareholders and board of directors, a record of all actions taken by the shareholders or board of directors without a meeting, a record of all actions taken by a committee of the board of directors in place of the board of directors on behalf of the corporation, and a record of all waivers of notices of meetings of shareholders and of the board of directors or any committee of the board of directors (C.R.S. 7-116-101).
Your filed articles of incorporation and bylaws are the first documents for your corporate records. Your corporation will generate many other official records such as:
- Meeting minutes
- Shareholder resolutions
- EIN verification letter
- Amendments and other filings made to the corporation over its lifetime
Organizations need a secure, centralized tool for managing and accessing sensitive records. Our Records Manager software offers a simple, efficient way for corporations to store records, track officers, directors, and shareholders, and customize meeting notifications.
Appoint Initial Directors

If the initial directors are not named in the articles of incorporation, they are appointed by the incorporator. The incorporator documents and signs this action for the corporate records.
Hold Organizational Meeting
Hold the organizational meeting of the incorporators or initial directors in compliance with 805 ILCS §5/2.20. At least three days written notice must be provided unless those entitles to notice sign a waiver. The meeting may held in or out of Illinois. Keep minutes of this meeting.

Consider Electing S-Corp Taxation
By default, your corporation is taxed as a C-Corporation. Some corporations, especially smaller ones, benefit from electing S-Corp tax treatment:
- C-Corps suffer from double taxation: the corporation pays taxes on profits then members pay taxes on their distributions. If profits exceed $250,000 per owner, you provide employee benefits, or you will re-invest most of your profit in the business, you may benefit from the low tax rates on retained earnings under C-Corp treatment.
- S-Corp treatment avoids double-taxation. It is generally the best choice for small businesses. To accomplish this, file Form 2553: S-Corp Election with the IRS.
Obtain Business Licenses & Permits
To run your business legally, you must obtain applicable licenses and permits. The easiest way to navigate the wide range of federal, state, and local requirements is to search by your business type and locality using the Small Business Administration Business License & Permit look-up tool.
Illinois Business License

Illinois does not have a general business license at the state level, but local licenses are often required.
