What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit tax identification number assigned by the IRS to business entities operating in the United States. It is used to identify a business for tax purposes, similar to how a Social Security number identifies an individual. Whether you're building a service marketplace, a product marketplace, or a B2B platform, you'll likely need an EIN.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your marketplace business requires an EIN. Generally, LLCs with multiple members, corporations, and businesses that hire employees need an EIN. Sole proprietorships without employees may use their Social Security number.
  2. Choose Your Business Structure: Decide on your business structure (LLC, corporation, etc.). This decision impacts your tax obligations and the information you'll need to provide on the EIN application. In DC, LLCs are popular for their flexibility and liability protection.
  3. Prepare Form SS-4: Complete IRS Form SS-4, the Application for Employer Identification Number. You can download the form from the IRS website. Ensure all information is accurate, including your business name, address, and the reason for applying.
  4. Submit Your Application: You can apply for an EIN online through the IRS website, by fax, or by mail. The online application is the fastest method and is generally recommended. Applying online gives you immediate access to your EIN.
  5. Receive Your EIN: Upon successful submission of your application, you will receive your EIN from the IRS. If you applied online, you'll receive it immediately. If you applied by fax or mail, you'll receive a confirmation letter.
  6. Notify District of Columbia: Ensure your business information is consistent across all state and federal agencies. While DC doesn't require separate EIN registration, keep your business license and tax registrations aligned with your EIN.
