What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the Internal Revenue Service (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. Accounting businesses in District of Columbia need an EIN to legally operate and fulfill their tax obligations.

How to Apply for an EIN

  2. Choose Your Business Structure: Decide on the legal structure of your accounting firm (e.g., LLC, PC, S-Corp). This decision impacts your tax obligations and liability. Note that the DC Board of Accountancy may have specific entity requirements for CPA firms.
  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.
