This guide will walk you through the process of getting an EIN for your software developer business in Kentucky in 2026.

What is an EIN?

An Employer Identification Number (EIN), also known as a Federal Tax Identification Number, 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. You'll need an EIN to hire employees, open a business bank account, and file certain tax returns.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your software development business structure requires an EIN. Generally, LLCs with employees or electing to be taxed as an S-Corp, corporations, and partnerships need an EIN. Sole proprietorships without employees may use their Social Security number, but an EIN can offer additional protection.
  2. Choose Your Business Structure: Decide on your business structure (LLC, S-Corp, C-Corp). This decision impacts your tax obligations and liability. Software developers in Kentucky often choose LLCs for their flexibility and liability protection.
  3. Prepare Form SS-4: You'll need to complete IRS Form SS-4, Application for Employer Identification Number. This form requires information about your business, such as its legal name, address, responsible party, and the reason for applying for an EIN.
  4. Apply Online: The easiest and fastest way to apply for an EIN is through the IRS website. The online application is available Monday through Friday, 7:00 a.m. to 10:00 p.m. Eastern Time.
  5. Submit Your Application: Once you've completed Form SS-4, submit it to the IRS. You can submit it online, by fax, or by mail. The online application provides immediate EIN issuance.
