Do I need an Employer Identification Number (EIN), also known as a Federal Tax Identification Number?
FAQ Top A: In short, the answer is yes. That number is a unique number used to identify your business. You’ll need it when registering your business with state or federal agencies. You must have an EIN if you sell goods and/or have employees. Occasionally, some sole proprietors choose to use their social security number (SSN) in lieu of an EIN; however, in today’s world where identify theft is a very real threat, it’s a safer bet to protect your SSN and use an EIN, even if you’re a sole proprietor.
