What Connecticut does differently

  • Immediately is the actual instruction. Most states give 10, 15, or 30 days. Connecticut says notify Revenue Services immediately when you go out of business or permanently stop paying wages, which leaves no comfortable reading.
  • Your accountant cannot do this for you. A third party cannot close a client's account in myconneCT. That single rule breaks the normal delegation model, and it is why Connecticut accounts sit open at firms that closed every other state without trouble. We can prepare everything and tell you exactly what to click, but the final action has to come from your own login.
  • Three bodies, and the third is easy to miss entirely. Paid family leave sits with the Connecticut Paid Leave Authority, which is not part of Revenue Services or the Department of Labor. An employer who registers for withholding and unemployment has done two thirds of the job.
  • Your accountant cannot close the account for you. A third party cannot close a client's account in myconneCT. That single rule breaks the normal delegation model and it is why Connecticut accounts sit open at firms that closed every other state without trouble. Decide who holds the login now.
