An Employer Identification Number (EIN), also known as a Federal Tax Identification Number (TIN), is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States for the purpose of identification. It functions much like a Social Security number for individuals, but for businesses. Obtaining an EIN is a crucial step for most new businesses, as it is required for various tax purposes, opening business bank accounts, and hiring employees.

Why You Need an EIN
Several scenarios necessitate the acquisition of an EIN:
- Operating as a Corporation or Partnership: If your business is structured as a corporation or a partnership, an EIN is mandatory.
- Having Employees: Any business that plans to hire employees must obtain an EIN to report employment taxes.
- Operating a Keogh Plan: If your business has a Keogh plan (a type of retirement plan for self-employed individuals), an EIN is required.
- Operating Certain Types of Trusts or Estates: Specific trusts and estates also need an EIN.
- Purchasing an Existing Business: If you are buying an existing business, you will likely need a new EIN.
- Filing for Bankruptcy: Businesses undergoing bankruptcy proceedings require an EIN.
Even if your business structure doesn’t explicitly require an EIN, it is often beneficial to obtain one. It helps to separate your personal Social Security number from your business finances, providing a layer of privacy and security. It’s also a prerequisite for opening a business bank account, which is essential for maintaining clear financial records and managing your business finances effectively.
How to Get an EIN
The most common and efficient way to obtain an EIN is by applying directly through the IRS website. This process is free of charge.
Online Application (Recommended)
- Visit the IRS Website: Navigate to the IRS’s “Apply for an Employer Identification Number (EIN) Online” page.
- Eligibility Check: Ensure your business meets the eligibility criteria for online application. Generally, this includes having a valid Taxpayer Identification Number (SSN, ITIN, or EIN) and a physical address in the United States or its territories.
- Complete the Application Form: You will be asked to provide detailed information about your business, including its name, address, responsible party’s information (the individual who has a final say over the business or who is responsible for the entity’s tax matters), and the type of business entity.
- Receive Your EIN Instantly: Upon successful submission and validation of your application, you will be assigned an EIN immediately. You can then download and print a confirmation letter.
Other Application Methods
While the online method is the fastest, other options are available:
- By Mail or Fax: You can download Form SS-4, Application for Employer Identification Number, from the IRS website, complete it, and then mail or fax it to the IRS. This method can take several weeks to process.
- By Phone: If you are an international applicant without a U.S. physical address or U.S. territory address, you can apply by phone by calling the IRS toll-free number.
Important Considerations
- Free Service: Applying for an EIN directly through the IRS is always free. Be wary of third-party websites that charge a fee for this service.
- One EIN Per Entity: Each business entity should have only one EIN.
- Responsible Party: The “responsible party” is a key individual in the application process. They must have a Social Security number (SSN), individual taxpayer identification number (ITIN), or existing EIN and be able to validate their identity.
Securing an EIN is a straightforward process that is essential for the legal and financial operation of most businesses. By following the IRS guidelines, you can obtain this vital identification number efficiently and without cost.
