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

As a personal trainer in Indiana, obtaining an Employer Identification Number (EIN) might be necessary as you grow your business. Whether you're transitioning from an employee to an independent contractor, opening your own studio, or expanding online, an EIN can offer significant advantages. This guide will walk you through the process of getting an EIN and why it's crucial for your personal training business in Indiana.

What is an EIN?

An EIN, or Employer Identification Number, is essentially a Social Security number for your business. It's a unique nine-digit number assigned by the IRS to identify your business for tax purposes. While sole proprietorships without employees can often use their Social Security number, an EIN becomes essential when you form an LLC, S-corp, or other business entity, or when you hire employees.

How to Apply for an EIN

  2. Choose Your Business Structure: Decide on the legal structure of your personal training business (e.g., LLC, S-Corp). This decision impacts your tax obligations and liability in Indiana.
  3. Gather Required Information: Collect all necessary information, including your business name, address (physical Indiana address), the responsible party's name and SSN, and the reason for applying.
  4. Complete the IRS Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. You can download it from the IRS website or complete the application online.
