What is an EIN?

An EIN, or Employer Identification Number, 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, used to identify it to the IRS for tax purposes. For Arizona nonprofits, an EIN is essential for opening bank accounts, hiring employees, and applying for 501(c)(3) status.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Arizona 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: Collect all necessary information, including the legal name of your Arizona 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 the EIN.
  3. Complete the Online Application (Form SS-4): Access the IRS website and complete Form SS-4, Application for Employer Identification Number, online. The online application is the fastest and most efficient way to obtain an EIN.
  4. Submit the Application: After completing Form SS-4, submit it electronically through the IRS website. Ensure all required fields are filled out accurately before submitting.
  5. Receive Your EIN: Upon successful submission, you'll receive your EIN. Print or save a copy of the confirmation notice for your records. The IRS will also mail you an official EIN confirmation letter (Form CP 575), but this can take several weeks.
  6. Integrate EIN into Formation Documents: Once you receive your EIN, include it in your Arizona nonprofit's articles of incorporation and other relevant formation documents. This ensures consistency and proper identification of your organization.
