How This Works

Cash donations are the simplest but often the least tax-efficient. With the 2026 standard deduction at $16,100 single / $32,200 married, your cash gift only provides marginal benefit if your total itemized deductions (cash + SALT + mortgage interest) exceed the standard deduction.

Donating appreciated stock is dramatically more efficient than selling and donating cash. You avoid the capital gains tax on the appreciation (saving 15-23.8% federal at high incomes) AND get a charitable deduction at fair market value. The combined benefit can be 25-40% larger than donating cash.

Donor-Advised Funds (DAFs) enable charitable bunching — contribute multiple years of giving in one year (immediate deduction), then distribute to charities over time. This converts otherwise-wasted giving (below the standard deduction) into deductible giving by concentrating it.

Qualified Charitable Distributions (QCDs) are the gold standard for retirees age 70½+. Up to $108,000 in 2026 can transfer directly from your IRA to a qualified charity. The QCD counts toward your RMD but is excluded from AGI entirely — bypassing not just income tax but also potential SS taxation and IRMAA Medicare premium increases.
