This guide will walk you through obtaining an EIN for your personal trainer business in Idaho in 2026, ensuring you're set up for success.

What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to identify your business entity. It's essentially a Social Security number for your business. While not every personal trainer needs one, it's often required when you form an LLC or corporation, hire employees, or operate as a partnership. It helps the IRS track your business for tax purposes. Obtaining an EIN is free and is a crucial step in legitimizing your Idaho personal training business.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your personal training business structure requires an EIN. Sole proprietorships without employees might not need one, but LLCs and corporations generally do. Consider your future plans; even if you don't need one now, you might later as your business grows.
  2. Choose Your Business Structure: Decide if you'll operate as a sole proprietorship, LLC, corporation, or partnership. This decision impacts your tax obligations and liability. For personal trainers in Idaho, an LLC offers liability protection.
  3. Gather Required Information: You'll need to provide information about your business, including its legal name, address, the responsible party (usually you), and the reason for applying. Ensure all information is accurate to avoid delays.
  4. Complete the IRS Form SS-4: This is the application form for an EIN. You can download it from the IRS website or apply online. The online application is generally faster and easier.
  5. Submit Your Application: You can apply for an EIN online, by mail, by fax, or by phone (for international applicants only). The online method is the quickest and most convenient.
  6. Receive Your EIN: If you apply online, you'll typically receive your EIN immediately. If you apply by mail or fax, it can take several weeks. The IRS will send you a confirmation letter with your EIN.
