What is an EIN?

An EIN, or Employer Identification Number, is a unique nine-digit tax ID assigned by the IRS to identify your business entity. It's essentially a social security number for your agency, allowing you to hire employees, open business bank accounts, and file taxes. Even if you don't plan to hire employees immediately, an EIN can provide credibility and streamline various business operations.

How to Apply for an EIN

  1. Determine Your Agency's Eligibility: Ensure your agency business structure (LLC, S-Corp, etc.) requires an EIN. Most agencies operating as multi-member LLCs or corporations will need one, while sole proprietorships may not unless they hire employees.
  2. Choose a Responsible Party: Designate a 'responsible party' – typically a founder, owner, or officer – who will control, manage, and direct the agency and its funds. This individual will be responsible for the EIN application.
  3. Complete the IRS Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. This form requires information about your agency, including its legal name, address, business activity, and the responsible party's details.
  4. Submit Your Application to the IRS: You can submit Form SS-4 online, by fax, or by mail. The online application is the fastest and most efficient method. Faxing can take up to 4 business days and mailing can take 4-5 weeks.
  5. Receive Your EIN: Upon successful submission, you'll receive your EIN from the IRS. If applying online, you'll receive it immediately. For faxed or mailed applications, allow processing time.
  6. Safeguard Your EIN: Treat your EIN like a social security number. Keep it confidential and only share it with trusted parties, such as your bank, accountant, and payroll provider.
