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

As a personal trainer in Connecticut, whether you're transitioning to independent contractor status, opening your own studio, or offering online training programs, obtaining an Employer Identification Number (EIN) might be necessary. This guide outlines the process of getting an EIN for your personal trainer business in Connecticut in 2026, and how Lovie can streamline the formation process.

What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to identify business entities. It's essentially a Social Security number for your business. While not every business structure requires an EIN, it's often essential for tax purposes, hiring employees, and opening business bank accounts.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your personal trainer business structure requires an EIN. LLCs with no employees can often use their SSN, but corporations and partnerships always need one. If you plan to hire in the future, it's best to get an EIN from the start.
  2. Prepare Form SS-4: Download Form SS-4 from the IRS website (irs.gov). This form requests information about your Connecticut personal training business, such as its legal name, address, responsible party, and the reason for applying for the EIN.
  3. Complete the Application: Fill out Form SS-4 accurately and completely. You'll need to provide details about your business activity (personal training), the date your business was established, and the accounting method you use.
  4. Submit Form SS-4: You can submit Form SS-4 online through the IRS website, by mail, by fax. The online method is the fastest and most efficient. The IRS prefers online applications.
  5. 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.
  6. Store Your EIN Safely: Your EIN is sensitive information. Store it securely and only provide it to trusted parties, such as your bank, accountant, or legal counsel.
