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

As a personal trainer in Illinois, whether you're operating independently, running a studio, or offering online services, an Employer Identification Number (EIN) is crucial for your business's financial and legal operations. This guide provides a step-by-step approach to obtaining an EIN for your personal training business in Illinois in 2026.

What is an EIN?

An Employer Identification Number (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, allowing the IRS to identify your business for tax purposes. Whether you're structured as an LLC or S-Corp, an EIN is often a necessity.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your personal training business meets the IRS requirements for obtaining an EIN. Generally, any entity other than a sole proprietorship without employees needs an EIN.
  2. Choose Your Business Structure: Decide on the legal structure of your personal training business (e.g., LLC, S-Corp). This will influence how you apply for the EIN. Note that in Illinois, LLCs provide liability protection.
  3. Gather Required Information: Collect all necessary information, including your business name, address, the responsible party's (owner, partner, member) name and SSN/ITIN, and the reason for applying.
  4. Complete the Online Application: Access the IRS website and complete the online EIN application form (Form SS-4). The online application is the quickest and easiest method.
  5. Submit Your Application: Review your application carefully before submitting it electronically through the IRS website.
  6. Receive Your EIN: Upon successful submission, you will receive your EIN immediately online. The IRS will also send you a confirmation letter (Form CP 575) via mail.
