IRS Form SS-4 (Apply for an EIN) – Fillable PDF

The IRS Form SS-4 is the official application used by businesses, nonprofits, and other entities to obtain an Employer Identification Number (EIN). An EIN functions like a Social Security Number for your organization and is required for tax filing, hiring employees, opening bank accounts, and more.

What Is IRS Form SS-4?

Form SS-4 collects basic information about the applicant, such as legal name, mailing address, type of entity, reason for applying, and the responsible party’s Social Security Number. The form is accepted by the Internal Revenue Service (IRS) in paper or electronic format.

When Do You Need an EIN?

  • Starting a new business or partnership
  • Hiring employees or contractors
  • Opening a business bank account
  • Filing certain tax returns (e.g., employment, excise, or pension plans)
  • Changing the structure of an existing entity

Instead of printing, scanning, or using a separate PDF editor, you can complete the official SS-4 directly in your browser:

  1. Click the "Fill out this form" button on this page.
  2. Wait a few seconds while the Formize PDF Filler app loads the fillable SS-4.

Common Mistakes to Avoid

  • Leaving the "Responsible Party" section blank – the IRS requires a name and SSN or ITIN.
  • Choosing the wrong entity type – select the option that matches your legal structure.
  • Using an outdated address – the EIN will be mailed to the address on the form.
  • Incorrect reason for applying – pick the most accurate reason from the list provided.

Download & Print Options

If you prefer a hard copy, you can still download the official PDF and print it. The fillable version on Formize mirrors the exact layout, so you can switch between online and paper versions without re‑entering data.
