What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit tax identification number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business, allowing the IRS to identify your company for tax purposes. Whether you're a solo practitioner or a large firm, an EIN is often mandatory for legal service businesses.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your California legal services business is eligible for an EIN. Generally, any entity formed as a corporation, LLC, partnership, or trust requires an EIN. Sole proprietorships typically only need an EIN if they hire employees or operate as a corporation or LLC.
  2. Choose Your Business Structure: Decide on the appropriate legal structure for your California legal services business. Options include a Professional Corporation (PC), Professional Limited Liability Company (PLLC), or general LLC. The choice impacts liability, taxation, and compliance requirements.
  3. Gather Required Information: Collect all necessary information before starting the EIN application. This includes the legal name of your California legal services business, its address, the responsible party's name and SSN/ITIN, and the date the business was formed or incorporated.
  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 way to obtain an EIN.
  5. Submit Your Application: Review your application carefully before submitting it to the IRS. Once you're satisfied with the accuracy of the information, submit the application electronically.
  6. Receive and Store Your EIN: Upon successful submission, you'll receive your EIN confirmation notice (Form CP 575) from the IRS. This notice is crucial for opening bank accounts and filing taxes. Store it securely.
