How to Get an EIN for Your Nonprofit Business in Indiana (2026)

Starting a nonprofit in Indiana is an exciting venture, but navigating the legal and tax requirements can be daunting. A crucial step is obtaining an Employer Identification Number (EIN) from the IRS. This guide provides Indiana nonprofits with a clear roadmap to securing an EIN in 2026.

What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit tax identification number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your organization. Nonprofits use their EIN to identify themselves to the IRS, open bank accounts, and apply for grants.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Indiana nonprofit meets the IRS requirements for obtaining an EIN. Generally, any organization that intends to hire employees or operate as a corporation or partnership needs an EIN.
  2. Gather Required Information: Before starting the application, gather all necessary information, including the legal name of your Indiana nonprofit, its address, the name and Social Security number of the responsible party (e.g., the president or treasurer), and the reason for applying for an EIN.
  3. Complete the Online Application (Form SS-4): The easiest way to apply for an EIN is online through the IRS website. The online application is available at IRS.gov and can be completed in one session. You'll need to complete Form SS-4, Application for Employer Identification Number.
  4. Submit the Application: After completing Form SS-4 online, submit the application electronically. The IRS will validate the information and, if everything is correct, issue your EIN immediately.
  5. Alternative Application Methods (If Necessary): While the online application is the fastest method, you can also apply for an EIN by mail or fax. However, these methods take significantly longer to process. Mail Form SS-4 to the address listed on the IRS website for Indiana. Fax the completed form to the fax number provided on the IRS website.
  6. Record and Safeguard Your EIN: Once you receive your EIN, keep it in a safe place. You will need it for various purposes, including opening bank accounts, filing taxes, and applying for grants. Do not share your EIN with unauthorized individuals.
