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.
When You Need a FEIN
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.
