What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States. It's used to identify your business for tax purposes, allowing you to hire employees, open business bank accounts, and file taxes with the IRS. For first-time founders, obtaining an EIN is a fundamental step in establishing your business's legal and financial standing.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your business entity is eligible for an EIN. Generally, any business operating as a corporation, partnership, or LLC, or those hiring employees, needs an EIN. Sole proprietorships typically only need an EIN if they hire employees or operate as a corporation or partnership.
  2. Gather Required Information: Before starting the application, gather all necessary information, including your business's legal name, address, the responsible party's name and Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN), and the reason for applying for the EIN.
  3. Apply Online via the IRS Website: The easiest and fastest way to apply for an EIN is through the IRS website. The online application is available 24/7 and is free. Search "IRS EIN application" to find the correct page.
  4. Complete the Application Form (Form SS-4): The online application is essentially an interactive version of Form SS-4. You'll need to provide detailed information about your business, including its structure, principal activity, and the number of employees you expect to hire.
  5. Submit Your Application: Once you've completed the application, review all the information carefully and submit it electronically. Upon successful submission, you'll typically receive your EIN immediately.
  6. Store Your EIN Safely: Your EIN is a sensitive piece of information. Store it securely and only provide it to authorized parties, such as your bank, accountant, or the IRS. Do not include it on marketing materials or public websites.
