What is an EIN?

An EIN, or Employer 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 your company for tax purposes. Even if you don't plan to hire employees immediately, an EIN is often required for opening a business bank account, obtaining business licenses, and filing certain tax returns.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your accounting business meets the IRS requirements for obtaining an EIN. Generally, any entity operating a business in the U.S. needs an EIN.
  2. Choose Your Business Structure: Decide on your business structure (e.g., LLC, PLLC, S-Corp). This decision impacts your EIN application, as different structures require different information.
  3. Gather Required Information: Collect all necessary information, including your business name, address, responsible party details (name, SSN/ITIN), and the reason for applying for an EIN.
  4. Apply Online via IRS Website: The easiest way to apply for an EIN is through the IRS website. The online application is available 24/7 and is generally processed immediately.
