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

Starting a business in retirement can be a rewarding way to stay active and supplement your income. If you're a retiree in Indiana launching a new venture, you'll likely need an Employer Identification Number (EIN). This guide provides a clear roadmap for obtaining an EIN for your retiree business in Indiana 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 essentially a Social Security number for your business. The EIN is used to identify your business to the IRS for tax purposes, and it's required for various business activities.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Indiana retiree business requires an EIN. Generally, LLCs with employees, corporations, partnerships, and those paying excise taxes need one. A single-member LLC without employees can use the owner's SSN, but an EIN offers privacy.
  2. Choose Your Business Structure: Decide on your business structure: LLC, corporation, or partnership. This impacts the EIN application. In Indiana, LLCs are popular for their liability protection and pass-through taxation, which can be advantageous for retirees managing retirement income.
  3. Gather Required Information: Collect the necessary information, including the responsible party's (owner, partner, member) name, address, and Social Security number. You'll also need to provide the business name, address, and the reason for applying for the EIN.
  4. Complete the Online Application: Access the IRS website and complete the online EIN application (Form SS-4). The online application is the fastest and easiest method. The IRS provides detailed instructions to guide you through each section.
  5. Submit Your Application: After completing the application, carefully review all the information before submitting it. Once submitted, you'll typically receive your EIN immediately if applying online.
  6. Receive and Store Your EIN: Upon successful submission, you'll receive your EIN. Store it securely, as you'll need it for banking, taxes, and other official business purposes. The IRS will provide a confirmation notice (Form CP 575).
