Starting an accounting business in Kentucky? Whether you're a CPA, bookkeeper, or tax preparer, you'll likely need an Employer Identification Number (EIN) from the IRS. This guide provides a comprehensive overview of how to obtain an EIN for your accounting business in Kentucky in 2026.

What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business, used to identify it for tax purposes. Even if you don't plan to hire employees right away, an EIN is often required for opening a business bank account, obtaining business licenses, and filing taxes as a corporation, LLC, or partnership.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your accounting business meets the IRS requirements for obtaining an EIN. Generally, any entity formed as a corporation, partnership, or LLC (especially those with more than one member or electing corporate tax treatment) is eligible.
  2. Choose Your Business Structure: Decide on the legal structure of your Kentucky accounting business. Common options include sole proprietorship, partnership, LLC, S-Corp, or C-Corp. Your choice impacts your tax obligations and EIN requirements.
  3. Gather Required Information: Before starting the application, gather all necessary information, including your business name, address, the responsible party's name and Social Security number, and the reason for applying for the EIN.
  4. Complete the IRS Form SS-4: The application for an EIN is made using IRS Form SS-4. You can download the form from the IRS website or complete the application online through the IRS EIN Assistant.
  5. Submit Your Application: If completing the paper form, you can submit it by mail or fax, though online application is highly recommended for faster processing. The IRS no longer accepts EIN applications via phone.
  6. Receive Your EIN: If you apply online, you'll typically receive your EIN immediately after submitting the application. If you apply by mail or fax, it can take several weeks to receive your EIN.
