If you’re starting a business, you may wonder, “What is an EIN for a business?” An EIN (Employer Identification Number) is a unique nine-digit number issued by the Internal Revenue Service (IRS) to identify your business entity for tax purposes. It functions like a Social Security Number (SSN) but is used exclusively for businesses.
Why Your Business Needs an EIN
An EIN is essential for various legal and financial functions, including:
- Opening a business bank account
- Filing federal and state taxes
- Hiring employees
- Applying for business licenses or credit
Whether you’re operating as an LLC, corporation, partnership, or nonprofit, an EIN helps establish your business identity and keeps your personal finances separate.
Who Needs an EIN?
You’ll likely need an EIN if your business:
- Has employees
- Operates as a corporation or partnership
- Withholds taxes on income (other than wages)
- Files employment, excise, or alcohol/tobacco/firearms tax returns
Even sole proprietors and single-member LLCs often obtain EINs to meet banking or vendor requirements.
