What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit 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 for tax purposes. Nonprofits in Idaho need an EIN to legally operate and fulfill their tax obligations.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Idaho nonprofit is eligible for an EIN. Generally, any organization that intends to hire employees or operate as a corporation (including a nonprofit corporation) needs an EIN.
  2. Prepare IRS Form SS-4: Download and complete IRS Form SS-4, Application for Employer Identification Number. This form requires information about your Idaho nonprofit, such as its legal name, address, responsible party, and the reason for applying.
  3. Choose Your Application Method: You can apply for an EIN online, by mail, by fax, or by phone (for international applicants only). The online application is the fastest and most efficient method.
  4. Apply Online (Recommended): Access the IRS's online EIN Assistant. Follow the prompts and enter the required information from Form SS-4. You'll receive your EIN immediately upon successful submission.
  5. Apply by Mail or Fax (If Necessary): If you choose to apply by mail, send Form SS-4 to the IRS address provided on the form instructions. If applying by fax, use the appropriate fax number listed on the IRS website. Note that mail and fax applications take significantly longer to process.
  6. Receive and Store Your EIN: Once your application is processed, you'll receive your EIN. For online applications, it's provided immediately. For mail or fax applications, it can take several weeks. Store your EIN in a safe and accessible place.
