What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit tax ID assigned by the IRS to business entities operating in the United States. It's like a Social Security number for your business, used to identify your marketplace for tax purposes, opening bank accounts, and hiring employees. Even if you don't plan to hire employees initially, an EIN is often required for marketplace businesses, especially those acting as payment facilitators or managing transactions between third parties.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Indiana marketplace business structure (LLC, Corporation, etc.) requires an EIN. Most LLCs with more than one member, or those that hire employees, need an EIN.
  2. Choose Your Responsible Party: Designate a responsible party – the individual who controls, manages, or directs the marketplace and its funds. This person must have a valid Taxpayer Identification Number (SSN or ITIN).
  3. Complete the IRS Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. You can download the form from the IRS website or complete the application online.
  4. Submit Your Application to the IRS: You can apply for an EIN online through the IRS website, by fax, or by mail. Online application is the fastest and most efficient method.
  5. Receive Your EIN: If you apply online, you'll typically receive your EIN immediately. If you apply by fax or mail, it may take several weeks.
  6. Safeguard Your EIN: Treat your EIN like a sensitive piece of information. Protect it from unauthorized access to prevent identity theft.
