If you’re starting a business or opening a bank account under your business name, you’ve probably asked: “How do I get an EIN?” An Employer Identification Number (EIN) is a unique number issued by the IRS for tax and identification purposes—much like a Social Security number, but for your business.
Step-by-Step: How to Get an EIN
1. Determine If You Need an EIN
You’ll need an EIN if:
- You have employees
- You operate as a corporation or partnership
- You withhold taxes on income (excluding wages)
- You have a Keogh plan or run certain types of organizations like trusts or estates
2. Apply Online Through the IRS
The fastest and easiest way is through the IRS EIN Online Application.
Requirements:
- You must have a valid Taxpayer Identification Number (like SSN or ITIN)
- You must apply during IRS hours (Mon–Fri, 7 a.m.–10 p.m. EST)
3. Apply by Mail or Fax
You can also fill out Form SS-4 and send it by:
- Fax: You’ll get your EIN in about 4 business days
- Mail: Processing takes up to 4 weeks
4. International Applicants
If you’re applying from outside the U.S. and don’t have an SSN or ITIN, you can still apply by phone at +1-267-941-1099 (for international applicants only).
