What is an EIN?

An EIN is a unique nine-digit tax identification number assigned by the IRS to business entities. It's like a Social Security number for your business, used for tax reporting and identification purposes.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Connecticut fintech business structure requires an EIN. LLCs with employees or multiple members, and all corporations need an EIN. Sole proprietorships without employees may not.
  2. Choose a Designated Responsible Party: Select the individual who will be the primary contact for the EIN application. This person must have a valid Taxpayer Identification Number (SSN or ITIN).
  3. Gather Required Information: Collect all necessary information about your Connecticut fintech business, including its legal name, address, business activity (NAICS code), and the responsible party's details.
  4. Complete the EIN Application (Form SS-4): Fill out IRS Form SS-4, Application for Employer Identification Number. You can apply online, by mail, by fax, or through a third-party service like Lovie, which automates the process.
  5. Submit the Application: Submit the completed Form SS-4 to the IRS. Online applications are processed immediately. Mailed or faxed applications can take several weeks.
