Welcome to our simple online tool for obtaining your Illinois Federal Tax ID. Click here to start now, or learn more below.

Illinois Federal Tax ID numbers are issued by the IRS in a nine-digit format such as 12-3456789.

They uniquely identify your business to the government in the same way that Social Security Numbers do for individuals. But various non-government vendors will also request the number during routine commerce in Illinois. For example, Illinois banks will require you to provide one before opening a business bank account.

If your answer is "Yes" to one or more of the questions below, you are in need of a Federal Tax ID in Illinois:

Are you opening a business bank account?
Do you have employees?
Do you operate your business as an LLC or any type of Corporation or Partnership?
Do you file employment tax returns, excise tax returns, or alcohol / tobacco / firearm tax returns?
Are you a Trust, Estate, Non-Profit, Farmers Cooperative, Real Estate Mortgage Investment Conduit, or Plan Administrator?
Do you have a Keogh plan?

Federal Tax IDs can go by many names in Illinois, including:

Employer Identification Number (EIN)
Federal Employer ID Number (FEIN)
Federal ID Number (FIN)
Federal Tax Number (FTN)
Taxpayer Identification Number (TIN)
Federal Taxpayer Identification Number (FTIN)
Or often times, just Tax ID or Tax Number
