What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number that identifies a business for tax purposes. It's essentially a social security number for the company. The Internal Revenue Service (IRS) issues EINs, and they're required for corporations, partnerships, and entities that pay employees.

Understanding the Purpose of an EIN

An Employer Identification Number (EIN) is a nine-digit number that serves as a unique identifier for businesses and other entities in the United States. It is issued by the Internal Revenue Service (IRS), and is used to track business income for tax purposes and to establish credit. It is also known as a Federal Tax Identification Number and is required for certain business activities.

An EIN is similar to a Social Security Number for an individual, as it is used to track business-related income. It also allows businesses to open a business banking account and apply for business loans. It is required for all businesses that employ staff, and is used to set up payroll tax accounts.

How to Apply for an EIN

The process of applying for an EIN is simple. The IRS offers two methods of applying: online and by mail.

  • Online: To apply online, you need to have a valid Taxpayer Identification Number (TIN), such as a Social Security Number (SSN). Filling out a short online form will allow you to immediately receive your EIN. This method is fast and easy.
