Annual Tax Practitioner Letter

The Connecticut Department of Revenue Services (DRS) has entered a period of sustained transition. As such, the agency has decided to revive its Annual Tax Practitioner Letter as another vehicle to communicate important changes to stakeholders.

In this publication:

  • an update on the DRS multi-year IT modernization initiative, including information on myconneCT, the new online tax filing system that will launch in May; and
  • several reminders for practitioners (and taxpayers) for this individual income tax filing season.
