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 business. Whether you're forming an LLC or PLLC in Delaware, you'll likely need an EIN to operate legally and manage your finances effectively.

How to Apply for an EIN

  2. Choose Your Business Structure: Decide on the legal structure of your Delaware therapy practice (e.g., LLC, PLLC, S-Corp). The structure affects your tax obligations and the EIN application process. Many therapists choose a PLLC to comply with Delaware licensing requirements.
  3. Gather Required Information: Collect all necessary information, including your business name, address, the responsible party's details (name, SSN/ITIN), and the reason for applying for an EIN.
  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 all the information you've entered and submit the application electronically through the IRS website.
