Methodology
Ordinary taxable income is computed after the standard deduction (or your custom deduction) from wages, other ordinary income, and short-term capital gains. Long-term gains are reduced by any remaining standard deduction and then taxed at 0%, 15%, or 20% based on where those dollars fall on the IRS rate schedule for your filing status.
Brackets for ordinary income match IRS Rev. Proc. 2025-32. Long-term thresholds follow the 2026 tax year tables in IRS Rev. Proc. 2025-32 sec. 4.03. For a full ordinary-income picture, use the federal income tax calculator.
