What is an EIN?

An Employer Identification Number (EIN) is essentially a Social Security number for your business. It's a unique nine-digit number assigned by the IRS to identify your business entity for tax purposes. You'll need an EIN to hire employees, open a business bank account, and file certain taxes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Idaho business entity is eligible for an EIN. Generally, LLCs, corporations, partnerships, and sole proprietorships with employees need an EIN.
  2. Choose Your Responsible Party: The 'responsible party' controls, manages, or directs the entity and the disposition of its funds and assets. This person must have a valid Taxpayer Identification Number (SSN, ITIN, or EIN).
  3. Complete the IRS Form SS-4: You can download Form SS-4 from the IRS website. This form requests information about your Idaho business, including its name, address, type of entity, and reason for applying for an EIN.
  4. Submit Your Application: You can apply for an EIN online through the IRS website, by fax, or by mail. The online application is the fastest and most convenient method.
  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. Safeguard Your EIN: Treat your EIN like you would your Social Security number. Protect it from unauthorized access to prevent identity theft.
