How to Get an EIN for Your Personal Trainer Business in California (2026)

As a personal trainer in California, obtaining an Employer Identification Number (EIN) might seem daunting, but it's a crucial step for structuring your business. Whether you're transitioning to an independent contractor, opening your own studio, or expanding your online training services, an EIN is often necessary for tax compliance and business operations. This guide walks you through the process of getting an EIN for your personal trainer business in California in 2026, and highlights how Lovie can simplify the entire formation process.

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 tax identification number used to identify your business entity. It's required for various business activities, including opening a business bank account, hiring employees, and filing certain taxes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your personal training business requires an EIN. Sole proprietorships without employees may not need one, but LLCs, S-Corps, and partnerships typically do.
  2. Choose Your Business Structure: Decide on the legal structure of your business (e.g., LLC, S-Corp). This decision impacts your tax obligations and liability. In California, LLCs are popular for liability protection, while S-Corps can offer tax advantages for established businesses.
  3. Gather Required Information: You'll need information such as your business name, address, the responsible party's name and SSN/ITIN, and the reason for applying for the EIN.
  4. Complete the Online Application (Form SS-4): The easiest way to apply for an EIN is through the IRS website. Complete Form SS-4, the Application for Employer Identification Number.
  5. Submit Your Application: Once you've completed the form, submit it electronically through the IRS website. The EIN is usually issued immediately upon successful submission.
  6. Receive Your EIN: Upon successful submission, you'll receive your EIN. You can then use it for all business-related activities.
