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. The EIN is used to identify your legal services business to the IRS, allowing you to hire employees, open business bank accounts, file taxes, and more. For legal professionals in D.C., understanding and obtaining an EIN is a foundational step in establishing a compliant and credible business.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your legal services business is eligible for an EIN. Generally, any entity operating a business in the U.S. needs an EIN. This includes sole proprietorships with employees, partnerships, LLCs, and corporations. In D.C., professional limited liability companies (PLLCs) formed by attorneys will require an EIN.
  2. Choose Your Business Structure: Decide on the appropriate legal structure for your legal services business. Common choices include a Limited Liability Company (LLC), Professional Limited Liability Company (PLLC), or a corporation (PC). The choice impacts your liability, taxation, and administrative requirements.
  3. Prepare Form SS-4: Complete IRS Form SS-4, Application for Employer Identification Number. You can download the form from the IRS website and fill it out online or manually. This form requires information about your business, including its legal name, address, responsible party, and the reason for applying.
  4. Apply Online: The easiest and fastest way to apply for an EIN is through the IRS website. The online application is available during business hours and typically provides immediate approval.
  5. Submit Your Application: If you prefer not to apply online, you can submit Form SS-4 via mail or fax. However, these methods will take significantly longer to process. The IRS mailing address for D.C. businesses is included in the Form SS-4 instructions.
  6. Receive Your EIN: If you applied online, you'll receive your EIN immediately after submitting the application. If you applied by mail or fax, it may take several weeks to receive your EIN. The IRS will send you a confirmation letter with your EIN.
