If you’re starting a business in Chicagoland (Chicago and surrounding areas), one of the most important early steps is getting an EIN (Employer Identification Number) from the IRS. This number is required for taxes, banking, hiring, and formal business operations in the U.S.
Here’s a simple, step-by-step guide to help you apply correctly and avoid mistakes.
What Is an EIN?
An EIN is a 9-digit federal tax ID issued by the IRS. It identifies your business for tax purposes, similar to how a Social Security Number identifies an individual.
It is used for:
- Tax filings
- Opening business bank accounts
- Hiring employees
- Applying for licenses and permits
Step 1: Form Your Business First
Before applying for an EIN, you must legally establish your business entity.
For example:
- LLC (most common for startups)
- Corporation
- Partnership
If you are forming an LLC in Illinois, you should first file your Articles of Organization with the state.
Step 2: Gather Required Information
Before starting the application, prepare the following:
- Legal business name
- Business address (can be physical or virtual office address)
- Type of business structure (LLC, corporation, etc.)
- Responsible party (owner or manager)
- Reason for applying (new business, hiring employees, banking)
- Business activity description
The IRS uses this information to set up your tax profile.
Step 3: Apply Online (Fastest Method)
The easiest and fastest way is applying directly through the IRS website.
Steps:
- Visit the IRS EIN application page
- Click “Apply for an EIN”
- Select your business structure
- Enter business details and responsible party information
- Submit the application
If everything is correct, your EIN is usually issued immediately.
Step 4: Alternative Application Methods
If you cannot apply online, you can also use:
- Fax (Form SS-4)
- Mail (paper application)
- International phone application (limited cases)
Fax or mail methods take longer, usually several days to weeks.
Step 5: Receive Your EIN Confirmation
Once approved, you will receive an official IRS confirmation letter (CP 575).
You should:
- Save a digital copy
- Print it for records
- Use it for banking and tax setup
This number will be permanently linked to your business.
