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. While not always mandatory, it's often required for various business operations, including opening a bank account, hiring employees, and filing taxes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Maine therapist business meets the IRS requirements for obtaining an EIN. Generally, any entity other than a sole proprietorship without employees will need an EIN.
  2. Choose Your Business Structure: Decide on your business structure (e.g., LLC, PLLC, S-corp). In Maine, therapists often form a Professional Limited Liability Company (PLLC) to protect personal assets. This choice impacts the EIN application.
  3. Prepare Form SS-4: Complete IRS Form SS-4, Application for Employer Identification Number. This form requires information about your business, including its name, address, responsible party, and reason for applying.
  4. Submit Your Application: You can apply for an EIN online through the IRS website, by fax, or by mail. The online application is the fastest method and is generally recommended.
  5. Receive Your EIN: Upon successful submission of your application, you will receive your EIN. If you applied online, you'll receive it immediately. If you applied by fax or mail, it may take several weeks.
  6. Verify Your EIN: After receiving your EIN, verify its accuracy on the IRS website using their EIN lookup tool (if available). This ensures that your EIN is correctly registered.
