How to Start an LLC in Illinois
LLCs are the most popular structure for small businesses in Illinois. That's because starting and running a limited liability company (LLC) is very simple and offers important benefits.
LLCs can protect your personal assets (car, house, savings) if something happens to your business. LLCs also offer credibility and options to save on taxes.
It’s easy to form an LLC in Illinois online yourself. Just follow these steps:
- Name Your LLC
- Choose a Registered Agent
- File the IL Articles of Organization
- Create an LLC Operating Agreement
- Get an EIN
Starting an Illinois LLC is Easy
You can apply for an Illinois LLC online by registering the Articles of Organization with the Secretary of State. The cost to create an LLC in Illinois is $150.
You can file online or by mail. Follow our How to Start an LLC in Illinois guide below to get started.
Step 1: Create A Name For Your Illinois LLC
Before you register your LLC, you'll need to come up with a name. Your business name needs to be catchy for branding purposes and legitimate for legal purposes.
We go into depth on this topic in our LLC naming guide. We’ll go over the basics below.
Naming Your LLC
First, brainstorm some possibilities. Use our LLC name generator to get the ideas flowing.
Next, make sure your name meets Illinois guidelines:
- it contains the words limited liability company, limited company, or the abbreviation LLC or L.L.C.
- it doesn't contain restricted words or phrases (these often include words like bank, attorney, and university) without approval
- it's distinguishable from any other entity or assumed name registered in Illinois
- full list of Illinois naming guidelines
Next, do an Illinois LLC name search with the Secretary of State to find out if your name is available in Illinois.
If your business name is available and meets guidelines, you’ll be able to register it when you file your Illinois Articles of Organization with the Secretary of State.
Is the URL available? Before you commit 100% to a name, check to see if there’s a good web domain available.
We recommend buying your domain right away because even if launching a business website isn’t on your radar right now, it will be soon.
Step 2: Appoint An Illinois Registered Agent
When you file your Articles of Organization, you'll need to list a registered agent.
A registered agent's job is to accept legal documents like service of process and tax notices for your LLC.
Your registered agent can be a person or a registered agent service. You can act as your own registered agent, but many business owners choose to use a registered agent service.
Here are a few things to think about before you decide to act as your own registered agent:
- You’ll need to be available during normal (9 am - 5 pm) business hours at the address you provide
- If you run your business from home, you’ll have to make your personal address public
- You could be served with a lawsuit in front of your family or coworkers
Recommended: Most registered agent services offer a year of registered agent service free when you form an LLC with them.
Step 3: File Articles of Organization
It’s time to officially form your LLC by filing your Articles of Organization with the Illinois Secretary of State.
Recommended: Now is a good time to decide if your LLC will be member-managed vs manager-managed.
You'll need to know the following information to complete each Article:
- Entity Name and Address
- Registered Agent Name and Registered Office Address
- Business Purpose
- Governing Authority Type (LLC Management Structure)
- Effective Date and Duration
For more detailed help with completing the form, visit our Illinois Articles of Organization guide.
Mail Your Articles of Organization:
Send the form and payment (payable to the Secretary of State) to:
Secretary of State
Department of Business Services Limited Liability Division
501 S. Second St., Rm. 351
Springfield, IL 62756
How long does it take to get an LLC approved? LLC processing takes 10 days online or by mail, but can be expedited for an additional fee.
Step 4: Create An Illinois LLC Operating Agreement
Creating an Illinois LLC operating agreement is the only way to legally lock down your LLC’s management and ownership structure. Having this document in place will give you something to return to if a dispute or lawsuit arises.
Even single-member LLCs benefit from having an operating agreement.
Your operating agreement should outline the following:
- Each member’s responsibilities
- How new members will be admitted
- How existing members may transfer or terminate their membership
- How profits and dividends will be distributed
You can add as many provisions as you want, as long as they don't conflict with Illinois business law. Take a look at our What is an Operating Agreement guide to learn more.

Step 5: Obtain An EIN (Employer Identification Number) For Your LLC
An Employer Identification Number (EIN) is like a Social Security number (SSN) for your company. The IRS and the state of Illinois will use this number to track your business activity.
Your EIN will come in handy when it’s time to:
- Open a business bank account
- File Federal and State taxes
- Hire employees
The best way to get an EIN for your LLC in Illinois is by using the free online application on the IRS website.

Steps After Forming an LLC
After forming your LLC, it's important to:
- Open a Business Bank Account. A business bank account legally separates personal finances from business finances. This separation is required to maintain your LLC's corporate veil (your limited liability protection).
- Research Illinois Business Licenses and Permits. For help, visit our How to Get an Illinois Business License guide. There are also business license services that can help.
- File Your Illinois LLC Annual Report. File online with the Illinois Secretary of State prior to the first day of the registration anniversary month.
