Starting a business and wondering "do I need an EIN as a sole proprietor"? The answer isn't always straightforward. Let's break down when it's mandatory, when it's smart, and how to get one in 5 minutes.
When Sole Proprietors Actually Need an EIN
Case: Hiring Your First Employee? The IRS Says Yes
Sarah runs a freelance design business under her SSN. When she hired an assistant last month, her accountant insisted she get an EIN. Why?" The moment you have employees, the IRS requires an Employer Identification Number for payroll taxes. Over 70% of sole props miss this rule until their first tax penalty (SBA 2023 report).

Pro Tip: Bookmark the Form SS-4 if applying by mail/fax.
