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, used to identify your company for tax purposes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Connecticut SaaS business is eligible for an EIN. Generally, any entity operating as a corporation, partnership, or employer is eligible.
  2. Choose Your Responsible Party: Designate a responsible party. This individual controls, manages, or directs the entity and the disposition of its funds and assets.
  3. Complete the IRS Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. You can download this form from the IRS website.
