Schedule K (Form 1065): Partners' Distributive Share Items. Labeled 'Schedule K' within a Form 1065 filing. Summarizes the total of all items of income, deduction, credit, and other information allocated among the partners; feeds into individual Schedule K-1s. Typically this schedule is part of the standard Form 1065 return packet and should be included in the Form 1065 subdocument. Only classify it separately when it is clearly a standalone schedule packet outside the core Form 1065 page sequence. Schedule K pages within a Form 8865 (foreign partnership) or Form 1120-S should remain part of that parent form's subdocument.
