The Schedule CT-SI, officially known as "Connecticut Schedule I - Nonresident or Part-Year Resident Income from Connecticut Sources," is a supplemental form required for nonresidents or part-year residents who need to report income derived from sources within Connecticut. It plays a crucial role in calculating the portion of income subjected to Connecticut state taxes. This form is attached to Form CT-1040NR/PY and helps in detailing income types, applying adjustments, and ensuring compliance with Connecticut tax laws.

Obtaining the Schedule CT-SI is straightforward. The form can be downloaded from the official Connecticut Department of Revenue Services (DRS) website. It is also commonly available through tax preparation software like TurboTax or professional tax preparers. For convenience, individuals can request a physical copy via mail or collect it in person from a local DRS office. This ensures accessibility for taxpayers who prefer traditional methods over digital access.
