What is an EIN?

An Employer Identification Number (EIN), also known as a Federal Tax Identification Number, 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, used to identify it for tax purposes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your consulting business meets the IRS requirements for obtaining an EIN. Generally, any entity other than a sole proprietorship without employees will need an EIN.
  2. Choose Your Business Structure: Decide on the legal structure of your consulting business (e.g., LLC, S-Corp, C-Corp). This will influence how you apply for the EIN.
  3. Gather Required Information: Collect all necessary information, including your business name, address, the responsible party's name and SSN/ITIN, and the reason for applying for the EIN.
  4. Complete the Online Application (Form SS-4): Access the IRS website and complete the online EIN application (Form SS-4). The online application is the fastest and most efficient method.
  5. Submit the Application: Review all the information you've entered and submit the application electronically through the IRS website.
  6. Receive Your EIN: Upon successful submission, you will receive your EIN immediately online. The IRS will also send you a confirmation letter (Form CP 575) by mail.
