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 business, used to identify your company for tax purposes. Even as an e-commerce business based in Idaho, you'll need one in many instances.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Idaho e-commerce business meets the IRS requirements for obtaining an EIN. Generally, if you're operating as a corporation, partnership, or hiring employees, you're eligible.
  2. Choose Your Business Structure: Decide on your business structure (e.g., LLC, corporation, partnership). This decision impacts your tax obligations and EIN requirements. In Idaho, LLCs are popular for e-commerce due to liability protection.
  3. Gather Required Information: Collect all necessary information, including your business name, address, the responsible party's name and SSN/ITIN, and the reason for applying for an EIN.
  4. Complete the Online Application (Form SS-4): Access the IRS website and complete the online EIN application (Form SS-4). The online application is the fastest and most efficient method.
  5. Submit Your Application: Review your application for accuracy and submit it electronically through the IRS website.
  6. Receive Your EIN: Upon successful submission, you will receive your EIN immediately online. You can then download, save, and print your EIN confirmation notice (CP 575).
