    Do you need to have an FEIN for a sole proprietorship in order to register for a sales tax permit in CT, or will a SSN be sufficient?

  • The form says “FEIN, if applicable” so I take that to mean that you can use your SSN. Sometimes when an online registration kicks back you can also call the state and have them manually run it for you. Good luck and let us know if it worked!
