Tax ID Guide

Understanding the EIN

Your Employer Identification Number (EIN) is your business's social security number. Learn why you need it and how to secure one.

Do You Need an EIN?

Most new businesses require an EIN to operate legally in the United States. Use this checklist to see if your entity qualifies:

You have employees

Even if you only have one employee, the IRS requires an EIN for payroll tax reporting.

You operate as a Corporation or Partnership

While some single-member LLCs can use an SSN, all Corps and Partnerships must have a unique EIN.

You want to open a Business Bank Account

Almost all financial institutions require an EIN to open an account under a business name.

The Application Process

1
Form SS-4

The official document used to apply for an EIN. You can download this in our Forms Library.

2
Responsible Party

You must designate one individual (the "responsible party") who controls or manages the entity.

Important Note

The IRS only issues **one EIN per responsible party per day**. If you are launching multiple companies, plan your filings accordingly.
