How to enter Connecticut PTE in ProConnect Tax

The PTE and Composite forms have undergone major re-writes for tax year 2024 and are not yet final. The instructions below will be updated for tax year 2024 when the forms are released. For more information see here.

Down below we'll go over how to enter PTE for Connecticut on Individual, Partnership, and S Corporate returns in ProConnect Tax.

Who Must File a Pass-Through Entity Tax Return

For the 2023 taxable year, every PE that does business in Connecticut or has income derived from or connected with sources within Connecticut must file Form CT‑1065/CT‑1120SI regardless of the amount of its income or loss. The PE must first complete either federal Form 1065, U.S. Return of Partnership Income, or federal Form 1120S, U.S. Income Tax Return for an S Corporation. Information on the federal return is needed to complete Form CT‑1065/CT‑1120SI.

PEs that receive a Schedule CT K‑1, Member's Share of Certain Connecticut Items, from another PE must also file Form CT-1065/CT-1120SI.
