How to Get an EIN for Your Side Hustler Business in Delaware (2026)

Starting a side hustle in Delaware is exciting, but understanding the administrative steps, like getting an Employer Identification Number (EIN), is crucial. This guide simplifies the EIN process for your Delaware-based side business in 2026.

What is an EIN?

An Employer Identification Number (EIN) is like a Social Security number for your business. It's a unique nine-digit number assigned by the IRS to identify your business for tax purposes. Even as a side hustler, you may need an EIN to operate legally and efficiently.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Delaware side hustle meets the IRS requirements for an EIN. Generally, this includes having a business structure like an LLC or needing to hire employees.
  2. Choose a Business Structure: Decide on your business structure (e.g., LLC, sole proprietorship). For a Delaware side hustle, an LLC offers liability protection. File the necessary formation documents with the Delaware Division of Corporations.
  3. Gather Required Information: Collect all necessary information, including your Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN), business name, and business address. If forming an LLC, have your Delaware Certificate of Formation details ready.
  4. Complete the IRS Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. This form can be completed online or downloaded and mailed. The online application is the fastest method.
  5. Submit Your Application: Submit the completed Form SS-4 to the IRS. The online application provides immediate EIN issuance. If mailing, processing times can take several weeks.
  6. Receive and Store Your EIN: Once your application is processed, you'll receive your EIN from the IRS. Keep this number in a safe place as you'll need it for various business activities.
