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. While not always required for single-member LLCs, it's often beneficial and sometimes mandatory.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Delaware business entity is eligible for an EIN. Generally, single-member LLCs, corporations, partnerships, and other business structures are eligible.
  2. Choose Your Business Structure: Confirm your business structure (e.g., LLC). In Delaware, LLCs are a popular choice for solo founders due to their flexibility and liability protection. Delaware offers strong LLC protections.
  3. Gather Required Information: Collect all necessary information, including your SSN (Social Security Number), business name, address, and the reason for applying for the EIN.
  4. Complete the IRS Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. You can download the form from the IRS website or complete the application online.
  5. Submit Your Application: Submit Form SS-4 to the IRS. You can apply online through the IRS website for immediate EIN issuance, or you can fax or mail the application.
  6. Receive Your EIN: Once your application is processed, you'll receive your EIN from the IRS. If you applied online, you can download and save your EIN confirmation immediately.
