This 2026 charitable deduction limit page is built to cap a qualifying cash gift at the entered percentage of contribution-base AGI. Charitable contribution ceilings determine the amount deductible this year; excess qualifying gifts may carry forward under separate rules. The implemented convention is “current-year deduction = min(qualifying cash contribution, contribution-base AGI × applicable ceiling percentage).”

The editable entries are contribution-base adjusted gross income, cash contribution to qualifying public charity, applicable agi ceiling. Use values from the document or measurement that governs this 2026 charitable deduction limit question; the defaults are only the worked fixture below. Organization type, property gifts, substantiation, elections and ordering among percentage buckets are excluded. If that 2026 charitable deduction limit condition is not true, choose a calculation that models the missing convention.
