5 Steps to Form an LLC in Illinois

1

Name Your Illinois LLC

The first step to starting your business is choosing a unique name that complies with Illinois state laws. Your business name must be distinguishable from any other entity already registered with the state.

Naming Requirements

  • Must contain the words "Limited Liability Company" or an abbreviation like "LLC" or "L.L.C."
  • Cannot contain words that confuse your LLC with a government agency (e.g., FBI, Treasury).
  • Certain restricted words (Bank, Attorney, University) may require additional paperwork and licensing.
2

Appoint a Registered Agent

Illinois requires all LLCs to appoint a Registered Agent. This is an individual or business entity authorized to receive service of process (legal mail) and official government correspondence on behalf of your LLC.

Why hire a professional? A Registered Agent must maintain regular business hours at a physical street address within Illinois. If you use your home address, it becomes part of the permanent public record. BookMyLLC provides this service, allowing you to use our address on state filings to protect your privacy.

3

File Articles of Organization

To officially create your LLC, you must file a formation document (typically called the Articles of Organization or Certificate of Formation) with the state. The state charges a non-refundable filing fee of $150.00.

4

Draft an Operating Agreement

An Operating Agreement is an internal document that outlines how your LLC will be run, managed, and financially structured. Even if you are a single-member LLC, having an Operating Agreement is crucial for proving that your business is a separate legal entity from yourself (maintaining the "corporate veil").

While you don't file this with the state, you will need it to open a business bank account. BookMyLLC includes a custom Operating Agreement in all of our packages.

5

Get an EIN from the IRS

An Employer Identification Number (EIN) is like a social security number for your business. You will need an EIN to hire employees, pay taxes, and open a US business bank account.

You can apply for an EIN for free directly with the IRS. However, if you don't have a US Social Security Number, the process can take weeks via fax. BookMyLLC specializes in obtaining EINs for both US residents and non-US residents.
