Note on Partner's Distributive Share (U.S. Federal Form 1065 / Schedule K-1):
  • A partner's share of partnership income, deductions, gains, losses, etc., is determined by the partnership agreement and reported on Schedule K-1.
  • While often based on profit/loss sharing percentages, the actual allocation for specific items can vary due to complex partnership tax rules (e.g., special allocations, Section 704(b) regulations).
  • This tool provides an *estimation* based on a simple prorata allocation using the percentage you enter. It is NOT a substitute for the official Schedule K-1 provided by the partnership.
Disclaimer: This tool is for informational purposes only and does not constitute tax advice. Consult a qualified tax professional or refer to the official Schedule K-1 for accurate reporting.
