An EIN (employer identification number) is a number issued by the U.S. IRS to identify a business for tax purposes. It’s sometimes called a Federal tax ID.
Do I need an EIN?
Most people do not need an EIN.
If you’re participating as an individual (not a business), you will typically use your Social Security Number (SSN) instead.
You generally only need an EIN if you are working as a registered business, such as:
An LLC
A corporation
A partnership
