Employer Identification Number

In short

A unique nine-digit number assigned by the IRS to identify a business entity. It's like a Social Security Number for your business.

What it means in a deal

Your new business entity will need an EIN for tax purposes, opening bank accounts, and hiring employees. You'll apply for this with the IRS after forming your entity. This number is crucial for all financial and legal documentation related to the business, including loan applications and tax filings.
