Step 1: Create A Name For Your Illinois LLC
Before you register your Illinois 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.

Using an Illinois Assumed Name (DBA)
An Illinois DBA (doing business as), also known as an assumed name, is any registered name that a business operates under that isn't its legal business name. An assumed name can be used by any type of business, including a sole proprietorship, partnership, or limited liability company (LLC).
Learn how to get a DBA in our Illinois DBA guide.
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. To learn more about Illinois Registered Agents, read our guide.
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: Northwest Registered Agent offers a free year of registered agent services when you form your LLC ($29 plus state fees).
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.
You can file online with the Secretary of State or fill out a hard copy of Illinois Form LLC-5.5 and mail it in or deliver it in person. The filing fee is $150.
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 Illinois 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 an operating agreement 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 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 in Illinois
After forming your Illinois LLC, it's important to:
Open A Business Bank Account
A business bank account helps separate personal expenses and company expenses, which is required to maintain your Illinois LLC's corporate veil. A corporate veil protects your personal assets from creditors in potential lawsuits against your LLC or Business.
Learn more by reading this guide to Banking for Entrepreneurs. For a multi-member LLC, you'll also want to set up capital accounts for LLC members. We also recommend checking out our review of the best business bank accounts.
Get A Business Credit Card
A business credit card will help separate personal and business expenses while building your company's credit history. A strong credit history will be useful for raising capital in the form of venture capital, angel investment, or small business loans.
Set Up Business Accounting
Hiring a business accountant is one of the best ways to ensure you’re taking advantage of LLC tax benefits; possibly saving you and your business thousands of dollars per year.
When forming an LLC in Illinois, it’s a good idea to start a relationship with a business accountant as soon as you start your business to help set your company up for success.

File Your Illinois LLC Annual Report
Illinois LLCs must file an annual report each year with the Secretary of State. This can be done online through Cyberdrive Illinois or by filing Form LLC-50.1: Annual Report by mail or in person. The filing fee is $75.
Understand Illinois State Tax Requirements
Illinois businesses selling a physical product are generally required to register for a seller’s permit through the MyTax Illinois website. Visit our Illinois Sales Tax guide to learn more about seller’s permits and Illinois sales tax.
Additionally, if you have employees in Illinois, you will need to register for unemployment insurance tax and employee withholding tax through the MyTax Illinois website.
Understand Your Illinois LLC’s Federal Tax Requirements
Most Illinois LLCs will need to report their income to the Internal Revenue Service (IRS) each year using Form 1065 Partnership Return (multi-member LLCs) or Form 1040 Schedule C (single-member LLCs).
How you pay yourself will affect your federal taxes. Visit our guide to learn more about how to pay yourself from your LLC.
Know Your Illinois LLC’s Federal Tax Election Options
Pass-through taxation entails a business’s profits passing through to the LLC member’s individual tax returns. Like a sole proprietorship, an LLC is taxed as a pass-through entity, also known as a disregarded entity.
Once this process is completed and after any tax-deductible expenses are taken out, the LLC members pay self-employment taxes and income tax on their portion of the business income.
Alternatively, Illinois LLCs can choose to elect to be taxed as an S corporation (S corp) or C corporation (C corp). If S corporation tax status is elected, LLC members can be taxed as employees of the business, potentially reducing tax burden.
