What is an EIN?

An Employer Identification Number (EIN) is essentially a Social Security number for your business. It's a unique tax identification number assigned by the IRS to identify your business entity. You'll need an EIN to open a business bank account, hire employees, file taxes, and more. Think of it as your business's official ID with the federal government.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Delaware business entity is properly formed and requires an EIN. Generally, LLCs with more than one member, corporations, and businesses that hire employees need an EIN. Single-member LLCs without employees may not need one, but it's often beneficial.
  2. Choose Your Application Method: You can apply for an EIN online through the IRS website, by mail (Form SS-4), or by fax (also Form SS-4). The online application is the fastest and most convenient method.
  3. Complete the EIN Application (Form SS-4): Whether applying online or via mail/fax, you'll need to complete Form SS-4. This form requires information about your Delaware business, including its legal name, address, responsible party (owner/officer), and the nature of your business activity.
  4. Submit Your Application: If applying online, simply submit the completed form electronically. For mail or fax applications, send the completed Form SS-4 to the appropriate IRS address or fax number (check the IRS website for the most up-to-date contact information).
  5. Receive Your EIN: If you apply online, you'll typically receive your EIN immediately after submitting the application. If applying by mail or fax, it can take several weeks to receive your EIN.
  6. Store Your EIN Safely: Your EIN is sensitive information. Store it securely and only provide it to authorized parties, such as your bank, accountant, or legal counsel.
