What Exactly is an EIN and Why Do You Need One?

An Employer Identification Number (EIN) is a unique nine-digit number issued by the IRS to identify your business entity for tax purposes. Think of it as a Social Security Number, but for your business. You’ll need it for various reasons, including:

Filing federal and state taxes
Hiring employees in Illinois
Opening a business checking account in Clinton County
Applying for local permits and licenses
Establishing business credit

Even if you’re operating a small business from your home in Aviston or a farm outside Germantown, an EIN streamlines business operations and ensures you’re compliant with federal and Illinois state regulations.

Registering your business with the Illinois Secretary of State
Obtaining any required local licenses from your city or township (e.g., New Baden, Beckemeyer, or Albers)
