What is an EIN?

An EIN, or Employer Identification Number, 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 business, used to identify your agency for tax purposes and other official transactions.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Idaho agency meets the IRS requirements for obtaining an EIN. Generally, any business entity operating in the US needs one.
  2. Choose Your Responsible Party: Designate a 'responsible party' – the individual who controls, manages, or directs the agency 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'll need to provide information about your Idaho agency, such as its legal name, address, business activity, and the responsible party's details.
  4. Submit Your Application: You can submit Form SS-4 online, by fax, or by mail. The online application is the fastest method and is generally recommended.
  5. Receive Your EIN: If you apply online, you'll typically receive your EIN immediately. If you apply by fax or mail, it can take several weeks.
  6. Verify Your EIN: After receiving your EIN, verify its accuracy by checking the confirmation notice. Ensure all the information matches your agency's details.
