What is an EIN?

An EIN is a unique nine-digit tax identification number assigned by the IRS to business entities. It's like a Social Security number for your business, used to identify your business to the IRS for tax purposes. Most businesses, especially those with employees or operating as corporations or partnerships, require an EIN.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Arizona white label business requires an EIN. Most LLCs with employees, corporations, and partnerships need one. Even a single-member LLC might need an EIN if it elects to be taxed as a corporation.
  2. Choose Your Business Structure: Decide on the legal structure of your white label business (LLC, S-corp, etc.). This choice impacts your EIN application and tax obligations in Arizona. Consider the liability implications of white-labeling.
  3. Gather Required Information: Collect all necessary information, including your business name, address, responsible party details (Social Security number, etc.), and the reason for applying for an EIN. For Arizona LLCs, include the date of formation.
  4. Complete the EIN Application (Form SS-4): Fill out IRS Form SS-4, Application for Employer Identification Number. You can apply online through the IRS website or by mail. The online application is generally faster.
  5. Submit Your Application: Submit the completed Form SS-4 to the IRS. If applying online, you'll typically receive your EIN immediately. Mailed applications take longer to process.
  6. Receive and Store Your EIN: Once your application is approved, you'll receive your EIN. Keep this number in a safe place, as you'll need it for various business-related activities.
