Starting your own business? Over 70% of solo entrepreneurs wonder: "Do I need an EIN for a sole proprietorship?" The answer depends on your situation - let's break it down.
Sole Proprietor EIN Requirements Explained
When You Must Get an EIN as a Sole Proprietor

- File excise tax returns
- Have a Keogh retirement plan
Pro tip: Apply for your EIN instantly via the IRS EIN Assistant.
