The Background

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.

Frequently Asked

Can I deduct charitable donations in 2026 if I don't itemize?+

Yes, for the first time since 2021: the One Big Beautiful Bill Act lets non-itemizers deduct up to $1,000 of cash gifts ($2,000 joint) beginning with 2026 returns. Itemizers deduct gifts above a new floor of 0.5% of adjusted gross income, up to 60% of AGI for cash and 30% for appreciated property. Most households with a mortgage and state taxes under the $40,400 SALT cap still take the $16,100 / $32,200 standard deduction.

Why donate appreciated stock instead of cash?+

You deduct the full market value and never pay capital gains tax on the appreciation. Giving $10,000 of stock with a $2,000 basis saves the deduction plus the 15% or 20% (plus 3.8% NIIT) tax on $8,000 of gain — up to $1,900 more than giving $10,000 of cash and keeping the stock. The shares must be held more than one year.

What is donor-advised fund bunching?+

Making several years of gifts in one year into a donor-advised fund, taking one large itemized deduction that clears the standard deduction, then granting to charities from the fund over the following years while taking the standard deduction. A couple giving $12,000 a year who bunch three years ($36,000) can deduct roughly $25,000 more over the cycle than giving annually.

What is a qualified charitable distribution?+

A direct transfer from a traditional IRA to a charity by someone 70½ or older, up to about $108,000 per person in 2026 (indexed). It is excluded from income entirely — better than a deduction — and counts toward the required minimum distribution at 73 or 75, which keeps income below IRMAA and Social Security taxation thresholds. It is the best strategy for most retirees who give.

Which strategy does the calculator recommend?+

It computes the after-tax cost of your gift under each method — cash, appreciated stock, a three-year DAF bunch, and a QCD if you are old enough — using your 2026 federal bracket, capital gains rate and other itemized deductions, and flags the cheapest. The right answer changes with age, whether you itemize, and how much gain is in the stock.
