Connecticut: Extended filing and payment deadline for 2024 composite income tax and passthrough entity tax returns
New forms not yet integrated into tax authority platform
The Connecticut Department of Revenue Services (DRS) extended the filing and payment deadline for 2024 state composite income tax and passthrough entity tax (PTET) returns to April 15, 2025.
The DRS has been working with third party software companies to integrate these new forms into their platforms, but the process is not expected to be completed sufficiently in advance of the original March 15, 2025, deadline.
