What is an EIN?

An EIN, or Employer Identification Number, is a unique nine-digit number assigned by the IRS to identify your business entity. It's essentially a Social Security number for your legal services business, used for tax purposes, opening bank accounts, and various other business operations. Even if you don't plan to hire employees immediately, an EIN is often required for legal entities like PLLCs and corporations.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your legal services business is eligible for an EIN. Generally, any entity formed as a corporation, partnership, LLC (including PLLCs for attorneys), or trust requires an EIN.
  2. Choose Your Entity Structure: Decide on the appropriate legal structure for your Connecticut legal services business. Options include PLLC, PC, LLC, or S-Corp. The choice impacts liability, taxation, and compliance requirements.
  3. Gather Required Information: Collect all necessary information, including the responsible party's name, address, Social Security number (or ITIN), and the legal name and address of your legal services business.
  4. Complete the IRS Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. This form requires detailed information about your legal services business, including its purpose, type of entity, and contact information.
  5. Submit Your Application: Submit Form SS-4 to the IRS. You can apply online through the IRS website, by fax, or by mail. Online applications are typically processed fastest.
  6. Receive and Store Your EIN: Once your application is approved, you'll receive your EIN from the IRS. Keep this number secure, as it's essential for all tax-related activities and business operations.
