How to Apply for an EIN in Delaware

An Employer Identification Number (EIN) is essential for most businesses operating in Delaware. It is used for tax reporting, hiring employees, opening business bank accounts, and more.

Steps to Apply for an EIN

  • Determine Eligibility: Your business must be located in the United States or U.S. territories, including Delaware.
  • Gather Required Information: Have your legal business name, address, Social Security Number or Individual Taxpayer Identification Number of the principal officer, and business structure ready.
  • Apply Online: The fastest and most efficient method is to use the IRS online EIN application portal. This service is available Monday through Friday during standard business hours.
  • Apply by Mail or Fax: Alternatively, you can complete Form SS-4 and send it to the IRS via mail or fax. This method takes longer but is useful if online access is unavailable.
  • Receive Your EIN: Once the application is processed, you will receive your EIN immediately online or within a few weeks by mail or fax.

Operational Considerations

  • Recordkeeping: Keep a copy of your EIN confirmation letter for your business records and future compliance needs.
  • Business Registration: Use your EIN when registering your business with Delaware Division of Corporations and for state tax accounts.
  • Payroll Setup: An EIN is required to report employee wages and payroll taxes if you plan to hire staff in Delaware.
  • Banking and Licensing: Most banks require an EIN to open a business account, and certain Delaware business licenses may also require it.

As of 2026, the IRS is the sole issuer of EINs, and applying through their official channels ensures compliance and accuracy.
