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 business, allowing you to hire employees, open business bank accounts, and file taxes. Even if you don't plan to hire employees immediately, an EIN can be beneficial for establishing business credit and legitimacy.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your college business entity is eligible for an EIN. Generally, any business entity, including LLCs, corporations, partnerships, and sole proprietorships with employees, can apply. As a student, confirm your business structure aligns with university policies.
  2. Choose Your Business Structure: Decide on the legal structure of your Arizona business (e.g., LLC, S-Corp, C-Corp). LLCs are popular for their simplicity and liability protection. Involve co-founders in this decision as needed. Lovie can advise on the optimal structure for your student business.
  3. Prepare Form SS-4: Complete IRS Form SS-4, the Application for Employer Identification Number. You'll need to provide information about your business, such as its legal name, address (consider using a registered agent if you don't want to use your dorm address), responsible party, and the nature of your business. Lovie can auto-fill this form for you.
  4. Apply Online: The easiest and fastest way to apply for an EIN is through the IRS website. The online application is available during specific hours (typically 7:00 a.m. to 10:00 p.m. Eastern Time, Monday through Friday).
  5. Receive Your EIN: After submitting your online application, you'll typically receive your EIN immediately. You can then download, save, and print your EIN confirmation notice (IRS Notice CP 575).
  6. Notify Arizona State Agencies (If Applicable): Depending on your business activities, you may need to notify the Arizona Department of Revenue and other state agencies of your new EIN. This is particularly important if you plan to collect sales tax or operate in a regulated industry.
