Model both sides
The best planning answer often comes from comparing scenarios, not maximizing one deduction in isolation.

The model applies the 2026 0.5%-of-AGI charitable floor, the $1,000/$2,000 nonitemizer cash limit, and the 5.4% high-income itemized-deduction reduction. It does not apply contribution-category percentage limits, carryforwards, appraisals, substantiation, related-use rules, qualified-charity status, or state deductions.
Coordinate the giving planEducational estimate, updated August 23, 2026. Compares standard-versus-itemized deductions over the entered period using selected 2026 federal limits and separately illustrates embedded-gain tax. A DAF contribution is not assumed to create an additional deduction beyond the entered gift.

Frequently asked questions
The calculator is intentionally explicit about what it does and does not decide.
What is bunching?
It means concentrating multiple years of gifts into one tax year to create itemized deductions, then using the standard deduction in other years.
Does a donor-advised fund create an extra deduction?
No. It can change timing by allowing a contribution now and grants to charities later. Deductibility, limits, substantiation, and control rules still apply.
Is appreciated property always deductible at fair market value?
No. Property type, holding period, recipient, related use, appraisal, and percentage limitations can reduce or defer the deduction.
