If your business operates in the U.S., you’ll need a Federal Employer Identification Number (FEIN)—also known as an EIN—to file taxes, open business bank accounts, and comply with federal regulations.
You’ll typically need an FEIN if you:
Hire employees
Operate as a corporation or partnership
File employment, excise, or alcohol/tobacco/firearms tax returns
Withhold taxes on income (other than wages) paid to a non-resident alien
Open a business bank account or apply for business licenses
If you’re unsure whether you need one, the IRS website offers an eligibility guide to help you decide.
You can apply directly through the IRS website using their secure online EIN application:
