S-Corporation Income Policy
S-Corp income flows through to owners via K-1. Add back non-cash expenses (depreciation, depletion, amortization), subtract short-term debt and non-deductible expenses, then apply ownership percentage. If two years are provided and Year 1 exceeds Year 2, income is averaged over 24 months. Otherwise, only the most recent year is used.
