Forming an Illinois Corporation is Easy
Forming a corporation in Illinois is a simple process that is achieved by filing the Articles of Incorporation with the Secretary of State. In the guide below, we will show you step-by-step how to register a corporation in Illinois.
Step 1: Create a Name For Your Illinois Corporation
When naming your Illinois corporation, you will need to:
- Follow Illinois Name Requirements
- Complete a Name Search With the Illinois Secretary of State
- Consider Securing a Domain Name (URL)
To learn more, read our How to Name a Business in Illinois guide.
First, you will need to choose a name that complies with Illinois Secretary of State naming guidelines:
- Your name must contain the word "corporation," "company," "incorporated," "limited," or an abbreviation of one of those words.
- Your name must be distinguishable from any existing business in your state. This includes Illinois reserved names.
- Your name cannot include any words that indicate the corporation is in the business of banking, insurance, or corporate fiduciary without authorization from the state Commissioner of Banks and Real Estate.
- If applicable, the name must:
- contain the word "trust" if it is organized to accept and execute trusts
- contain the word "pawners" if it is organized as a pawners' society
- contain the word "cooperative" if it is organized as a cooperative association for pecuniary profit.
- Your name cannot include words that could confuse your corporation with a government agency (FBI, Treasury, State Department, etc.).
- Your name must be the name under which your corporation conducts business unless you register for an assumed name.
You can also read the Illinois state statute that covers corporation naming guidelines for more information.
Name Search With the Illinois Secretary of State
You will need to check name availability by using the Secretary of State’s website to do an Illinois Business Entity Search.
This tool is also useful if you decide to register an assumed name or DBA (Doing Business As) for your company. For detailed information about setting up a DBA for your Illinois corporation, check out our How to File a DBA in Illinois guide.
If you have a name in mind, but you aren’t ready to officially form your corporation, you can reserve your name. Your business name can be reserved for 90 days by filing an Application for Reservation of Name with the Illinois Secretary of State.
The Illinois Application for Reservation of Name form can be filed by mail. There is a $25 fee to file an Illinois Name Reservation.
Secure Domain Name
We recommend checking to see if your business name is available as a web domain (URL). Even if you don't plan to make a business website today, you may want to buy the web address in order to prevent others from acquiring it. It’s free to search.
Once you reserve a domain name for your corporation, it’s time to set up a business phone service to improve customer support and boost credibility. Our first pick is Nextiva because of its quick setup and variety of helpful features. Try Nextiva.

Step 2: Choose an Illinois Registered Agent
When you file your Illinois Articles of Incorporation, you will be asked to give the name of your Illinois registered agent.
Who Can Be a Registered Agent? Your registered agent can be an individual, business entity, or professional registered agent service. A registered agent must:
- be 18 years or older
- have a physical address in the state where business activity is conducted
- always be available (in person) during normal business hours
ZenBusiness offers one year of free registered agent services with their corporation formation package ($39 + State Fees).
Step 3: Choose Your Illinois Corporation’s Initial Directors
You must appoint at least one director who, among other things, will oversee your Illinois corporation until the first shareholder meeting.
The directors of a corporation are in charge of the adoption, amendment, and repeal of the operational bylaws as well as the supervision, election, and removal of officers.
Later you will prepare an “Incorporator Statement” with complete names and addresses of each director and keep it in your corporate records book. For now, you only need at least one initial director to list on your Articles of Incorporation.
Step 4: File the State of Illinois Articles of Incorporation
Now that you have chosen a registered agent and at least one director, it’s time to make your corporation official by filing the Articles of Incorporation with the Illinois Secretary of State.
The Articles of Incorporation will disclose some basics of your business for the public record, including:
- Corporate name and statement of purpose
- Corporate registered agent name and street address
- Number of authorized shares corporation is allowed to issue
- Directors’ names and addresses
- Incorporators' names and addresses
- The estimated value of property owned
- The estimated gross amount of business
Filing Fee: $150
Submit the completed Articles of Incorporation form in duplicate, along with the filing fee, using one of three options:

Set Up a Corporate Records Book
Think of this as the hard-copy record book where all critical corporate documents are kept, like your state of 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.
Prepare Bylaws for Your Illinois Corporation
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.
In your bylaws, be sure to include:
- How the corporation will be governed – 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
NOTE: A corporation’s bylaws will supplement any rules set forth by the federal government or the state.

Conduct Your First Board of Directors Meeting
An organizational meeting is the first official meeting of your corporation.
These are some of the things that are discussed in a typical organizational meeting:
- Taking attendance to show you have a quorum (minimum number needed)
- Appointing temporary officers, chairmen, secretary, etc.
- Adoption of the bylaws
- Adoption of conflict of interest policy
Don’t forget to record “minutes” of the meeting and have it signed by all attending directors. Here are some corporate minutes templates to help you get the ball rolling.
Protect Your Assets and Stay Compliant
Get an EIN
The Employer Identification Number (EIN), or Federal Tax Identification Number, is used to identify a business entity. It is essentially a social security number for the company.
Why do I need an EIN? An EIN is required for the following:
- To open a business bank account for the company
- For Federal and State tax purposes
- To hire employees for the company
To learn more about EINs, read our What is an EIN guide.
Open a Bank Account For Your Illinois Corporation
There are two critical reasons to open a unique corporate bank account.
The first is that separating your personal assets from your business assets adds another layer of protection in the event that your business is sued.
The second is that syncing a single account with business accounting software will make managing your finances much easier.

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.

Accounting For Your Corporation
It's important to get your books in order, even if you haven't officially opened for business. A well-managed accounting system will help you:
- Track your business finances, including bills, expenses, and income.
- Simplify and file your annual taxes.
You can maintain your accounting in two ways:
- Use a DIY accounting software. This can come with an increased risk of errors especially when starting a new business.
- Hire an accounting service. They can provide comprehensive advice to help optimize your bookkeeping and taxes as well as additional services such as payroll etc.

What is an S Corporation?
An S corporation (S corp) is an incorporated business that is taxed as a pass-through entity. This means that S corps do not pay federal taxes on their business income. Instead, the business profits "pass-through" to the owners of the S corp, who are also known as shareholders. Then, the shareholders pay income tax and report their share of the profits in the form of salaries on their individual tax returns, which are then taxed.
In order to elect an S corporation status for tax purposes, corporations will need to file form 2553 Election by a Small Business Corporation. The form must be signed by all shareholders and must be filed within two months and 15 days after the start of the initial tax year.
To learn more, read our What is an S corporation guide.
