How to Get an EIN for Your Serial Entrepreneur Business in Indiana (2026)

As a serial entrepreneur in Indiana, you're likely juggling multiple ventures. An Employer Identification Number (EIN) is crucial for each business entity, especially as you scale. This guide simplifies the EIN application process, highlights Indiana-specific considerations, and shows how Lovie can streamline your multi-entity management.

What is an EIN?

An EIN, or Employer Identification Number, is like a Social Security number for your business. It's a unique tax ID assigned by the IRS, used to identify your business entity for tax purposes. Even if you don't have employees, an EIN is often required for opening business bank accounts, obtaining licenses, and filing taxes for your Indiana LLC or corporation.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Indiana business entity (LLC, corporation, etc.) is properly formed and requires an EIN. Most multi-member LLCs and corporations need one. Single-member LLCs may need one for specific reasons (employees, excise taxes).
  2. Choose Your Responsible Party: The “responsible party” controls, manages, or directs the entity and the disposition of its funds and assets. This is usually you, the serial entrepreneur, but can be someone else in your Indiana business.
  3. Complete the IRS Form SS-4: You can download Form SS-4 from the IRS website. This form requires detailed information about your Indiana business, including its legal name, address, business activity, and the reason for applying for the EIN.
  4. Submit Your Application: You can apply for an EIN online through the IRS website, by mail, by fax, or via a third party. The online application is the fastest method and typically provides immediate EIN issuance.
  5. Receive Your EIN: If you apply online, you'll receive your EIN immediately after submitting the application. If you apply by mail or fax, it can take several weeks to receive your EIN.
  6. Store Your EIN Safely: Your EIN is sensitive information. Store it securely and only provide it to authorized parties, such as your bank, accountant, or the Indiana Department of Revenue.
