EIN & Business Registration

An Employer Identification Number (EIN) is your business's federal tax ID. It's required for most business activities: opening bank accounts, hiring employees, filing taxes, and applying for licenses.

What Is an EIN?

A 9-digit number (XX-XXXXXXX) issued by the IRS. Used to identify your business entity. Required for LLCs, corporations, partnerships, and sole proprietors with employees or excise tax obligations. Sole proprietors without employees can use their SSN instead, but getting an EIN is still recommended to protect your personal identity.
