Step 3: Hold an Organizational Meeting
Before you officially file the Articles of Incorporation in Step 4, you will need to hold an organizational meeting to complete the following tasks:
- Fill out and execute the Articles of Incorporation
- Create and approve bylaws
- Select your initial director(s)
- Determine your share structure
- Execute an Incorporator’s Statement
Create and Approve Corporate Bylaws
Bylaws are the rules that determine how your organization will be governed and run. You can think about the bylaws as a constitution for your corporation. It makes the rules and priorities clear for everyone involved.
A corporation’s bylaws will supplement any rules set forth by the federal government or the state.
In your bylaws, be sure to include:
- How the corporation will be governed, including the role of directors and officers
- How meetings are held, voting procedures, electing officers or directors
- How records will be kept and managed
- How disputes will be handled
- How bylaws will be added/amended in the future
- The date of the annual shareholder meeting
- How to negotiate contracts
- Fiduciary duties to the corporation (i.e. acting in the best interests of the corporation)
- What constitutes a quorum for voting purposes
What is a Quorum? A Quorum is the minimum number of members that must be present at a meeting to make the proceedings of the meeting valid, including any of the votes held therein.
Ready to get started? These bylaws templates can be customized to suit the needs of your incorporated business.
Appoint Initial Directors
You must appoint at least one director who will oversee your Illinois corporation until the first shareholder meeting.
A corporate director is in charge of the adoption, amendment, and repeal of operational bylaws as well as the election, supervision, and removal of officers.
After forming the corporation, the incorporator(s) — or initial director(s), if named on the formation documents — should call an organizational meeting. During this initial meeting, either the incorporator(s) will elect the board of directors or the initial director(s) will appoint the officers.
Choose a Share Structure and Strategy
A share of stock is the unit of ownership of a corporation. Each share of stock represents a percentage of ownership of the company. For example, if a corporation issues one share of stock the shareholder (stock owner) would then own 100% of the corporation.
Shares can be structured into classes. Each class, termed a share class, holds different rights and privileges. You can have multiple classes and each class can hold any number of shares.
Authorized Shares: the number of shares the corporation is allowed to issue.
Issued Shares: the total number of shares actually issued to shareholders.
Share Class: a group of shares that has a unique set of rights and privileges.
In Illinois, the Articles of Incorporation form allows you to indicate if the corporation will issue more than one authorized share class.
NOTE: We recommend starting with a high number of authorized shares. Many attorneys suggest 10 million. By starting with a high number, you have the flexibility to issue shares as needed without paying legal fees to increase your initial authorized shares amount.
Create and Execute an Incorporator’s Statement
The incorporator(s) should sign an Incorporator’s Statement with complete names and addresses of each initial director and store it in the corporate records book.
This document names the initial director(s) that will serve until the board of directors is elected during the first shareholder’s meeting. It should be stored with the rest of your corporate records.

Authorized shares are the number of shares that a corporation is allowed to issue. This number is initially set by the incorporator on the corporation’s formation documents and can be increased later by going through a legal process. Issued shares are the shares that have actually been distributed to shareholders.
Step 5: Get an EIN for Your Illinois Corporation

How to Run an Illinois Corporation
It is very important to adhere to the formalities of running a corporation. In order to protect your personal assets, and not allow creditors or municipalities to pierce your corporate veil, you must:
- Maintain up-to-date bylaws
- Set up a corporate records book
- Hold required annual meetings
- Give notice of meetings when applicable
- Keep accurate meeting minutes
Maintain Your Illinois Corporation Bylaws
You must maintain up-to-date bylaws to protect your corporate veil.
If you want to amend a section or article of your corporation’s bylaws, you must call a special meeting with the board of directors. During this meeting, a copy of your proposed changes should be distributed to the board members. Depending on your bylaw structure, either a majority vote or minimum vote will be required to pass the amendment.
After the first meeting, notices must be sent to the corporation’s shareholders. A second meeting will need to be held with all voting parties to either approve or disapprove your proposed amendments.
Set up a Corporate Records Book
Think of this as the hard-copy record book where all critical corporate documents are kept, like your Illinois Articles of Incorporation, bylaws, meeting minutes, stock certificate ledger, stock transfer documents, etc.
You should keep the corporate records book at your principal location. Corporate records book kits can be purchased online, or you can use a large generic binder to store your records.
Hold Periodic Board Meetings and Record Minutes
You must hold regular corporate meetings to maintain your business's management structure.
Annual Shareholder Meeting
Corporations in Illinois must hold an annual shareholder meeting. The first annual shareholder meeting should occur soon after formation. During this meeting, the shareholders elect the board of directors. Your corporate bylaws should note the date of your annual shareholder meeting.
Corporations might also need to conduct “special” board of director’s meetings. These meetings are called to discuss important business matters that will affect the corporation. Your state may have unique meeting notice requirements for special meetings.
Notice of Meetings
If your corporation has more than one shareholder, you will need to provide formal notice of meetings to owners (shareholders), employees, and officers before the meeting occurs. The notice must provide the following information:
- Whether the meeting is a regular or special meeting
- Where the meeting will be held
- When the meeting will occur
When a meeting must be held at the last minute, without formal notice of the meeting, a waiver of notice must be signed by all eligible people stating that they are giving up the right to receive formal notice as laid out in the bylaws and formation documents.
Meeting minutes are legally required in Illinois. Well-recorded minutes are indispensable during disputes and court actions.
For single-shareholder corporations (common for small business owners), minutes general only need to record the following:
- The date of the meeting
- A note that it was a joint meeting of the shareholders and board of directors
- When the next election of the board of directors will meet if that date is part of your corporate bylaws
Several companies offer corporate minutes templates. To learn more, read our review of the Best Corporate Meeting Minutes Templates.

Is a Corporation Right For You?
Protect Your Business & Personal Assets
To maintain personal asset protection, it is essential to have dedicated business banking and business credit accounts.
When your personal and professional accounts are mixed, personal assets like your home or vehicle are at risk in the event your Illinois corporation is sued. This is also known as piercing the corporate veil.
You can protect your Illinois corporation by following these two steps:
1. Get a Business Bank Account
Opening a business bank account protects your personal assets and legitimizes your corporation. Separating your professional account from your personal account also simplifies your business’s tax filing and accounting processes.
To open a bank account for your Illinois corporation, you will need an Employer Identification Number (EIN) and your corporation’s formation documents.

2. Open a Business Credit Card
Much like a business bank account, a dedicated business credit card will help your Illinois corporation separate your personal and professional expenses.
In addition to this, a business credit card will also help build your business’s credit history, which can be used to raise capital for your corporation. A higher business credit score will also help your business obtain loans and higher credit limits later on.
Small business credit cards also offer benefits that personal credit cards do not, such as business-specific cash back rewards and travel perks. Learn about the best small business credit cards.

3. Establish and Build Your Business Credit Score
Building business credit involves a number of factors, including establishing your business’s fundability, getting listed with the most important business credit agencies, and establishing credit lines while keeping them in good standing to build your score.
A good business credit score can help with many things, including credit cards that are issued in your business’s name instead of depending on your personal credit score, better interest rates on loans, higher lines of credit, and more.
All of these factors help protect your personal assets by making your business the entity responsible for the liability instead of yourself.
4. Hiring a business accountant:
- Prevents your business from overpaying on taxes while helping you avoid penalties, fines, and other costly tax errors
- Makes bookkeeping and payroll easier, leaving you with more time to focus on your growing business
- Helps effectively manage your business funding and discover areas of unforeseen loss or extra profit

- Workers' Compensation Insurance provides coverage for employees’ job-related illnesses, injuries, or deaths. Get a free quote with ADP.

- Your name

Illinois Corporation FAQ
Why Form a Corporation?
There are a number of good reasons to form a corporation. Some of the advantages include:
- Limited liability protection
- Unlimited capital generation
- Corporate tax benefits
- A more formal management structure
- Appeal to investors
To fully realize the benefits of incorporating, you will want to consider your company’s capital needs, profits, and management and ownership structure to make sure forming a corporation is the best business structure for you.
To learn more about what business structure is best for you, read our How to Choose a Business Structure guide.
What Type of Corporation Should I Form?
The best type of corporation for your business depends on many factors. Here are some different types of corporations:
- C corporations (C corps) are owned by stockholders, have a board of directors, and hold annual meetings.
- S corporation (S corp) is a type of tax classification. Unlike a C corp, an S corp can pass-through income to its shareholders for tax purposes. S corps are limited to 100 shareholders.
- Professional corporations are generally for corporations that require certain licensed individuals (e.g., doctors, attorneys, etc.).
- Nonprofit corporations use profits to advance the company’s mission rather than distributing them to shareholders.
You should carefully consider your business’s structure, goals, and financial situation before selecting your corporate structure.
Should I Form a Corporation or an LLC?
A limited liability company (LLC), unlike a sole proprietorship or a general partnership, offers personal asset protection in the event that your business is subject to legal action. Additionally, unlike corporations, LLCs are also simple to form, simple to maintain, and are able to avoid “double taxation.”
That being said, corporations have an easier time raising capital than an LLC and they enjoy several tax benefits that LLCs do not, such as a lack of self-employment tax.
Deciding which is better—a corporation or an LLC—depends on your business’s specific situation. Your company’s size, structure, goals, and more will determine if it is better to form a corporation or form an LLC.
To learn more about which business structure is best for you, read our guide to choosing a business structure.
What is the Best State to Start a Corporation In?
While several states have laws designed to make them more attractive for corporations, the best state to incorporate in is generally the one where you are located and do the majority of your business.
Certain corporate tax benefits or other laws may look appealing, but you may end up complicating things and paying taxes and meeting compliance regulations in multiple states.

For more information about opening a company in the USA, read our guide.

How Much Does It Cost to Incorporate?
The cost of incorporating (filing formation documents such as Articles of Incorporation, a Certificate of Formation, etc.) is between about $45 and $300, depending on your state. There may also be attorney’s fees and a registered agent fee, among others.

Professional corporations that require licensed individuals may need certain permits and licenses to operate their businesses.
Do Corporations Have Yearly Filings?

S corps are taxed differently, with profits passing through to the owners’ individual tax returns. For more information, check out our What is an S Corporation page.
