What is an EIN?

An EIN, or Employer Identification Number, is essentially a social security number for your business. Issued by the IRS, it's a unique nine-digit number that identifies your business entity for tax purposes. It's essential for opening a bank account, hiring employees, and filing business taxes.

How to Apply for an EIN

  1. Determine Your Business Structure: Decide on your business structure (LLC, C-Corp, S-Corp, etc.). In Arizona, LLCs and C-Corps are popular choices. Consider the liability protection and tax implications of each, especially given the data breach risks in cybersecurity.
  2. Check Name Availability: Ensure your desired business name is available in Arizona. Search the Arizona Corporation Commission's website to confirm name availability and that it does not infringe on existing trademarks.
  3. File Formation Documents: File your formation documents (Articles of Organization for an LLC or Articles of Incorporation for a C-Corp) with the Arizona Corporation Commission. This officially creates your business entity.
  4. Apply for an EIN Online: The easiest way to apply for an EIN is through the IRS website. The online application is free and generally takes only a few minutes to complete. You will need to provide information about your business, including its name, address, and responsible party.
  5. Receive Your EIN: Upon successful submission, you will receive your EIN immediately online. You can download and save the confirmation notice (Form CP 575).
  6. Update Business Records: Once you have your EIN, update all your business records, including bank accounts, vendor agreements, and licensing applications, with your new EIN.
