Charitable Deduction Calculator 2026: Standard vs Itemize, Bunching and Donor-Advised Funds
2026 is the first year of new rules for charitable gifts: a deduction for people who do not itemize, a floor of 0.5% of AGI for people who do, and a cap on what itemized deductions are worth in the top bracket. Enter your income, your other deductions and what you plan to give, and the tax engine shows what the gift saves this year, and whether putting several years of giving into 2026 through a donor-advised fund beats giving every year. A gift counts for 2026 only if it is made by December 31, 2026.
Is my charitable gift deductible in 2026, and does bunching help?
From 2026 a gift reduces your federal tax in one of two ways. If you take the standard deduction, cash gifts to a charity (not to a donor-advised fund) give a separate deduction of up to $1,000, or $2,000 on a joint return. If you itemize, only the part of your gifts above 0.5% of your AGI counts, and in the top bracket the benefit is capped at 35 cents on the dollar (IRC §170(p), §170(b)(1)(I), §68). Example: a married couple aged 68 and 66 with $90,000 of pension and IRA income, $50,000 of Social Security, $14,000 of state and property tax and $9,000 of mortgage interest, giving $12,000 a year. Their itemized deductions would be $34,338 after a $663 floor, still below the standard deduction of $35,500, so the gift cuts their 2026 tax by only $240. Putting three years of giving into a donor-advised fund in 2026 lifts that year’s deduction to $58,338; over 2026–2028 they pay $2,022 less federal tax than giving every year (2027 and 2028 PROJECTED).

The 2026 rules in one place
If you do not itemize: cash gifts to charities give a deduction of up to $1,000 ($2,000 married filing jointly) in addition to the standard deduction. Gifts to a donor-advised fund or a supporting organization do not count for it.
If you itemize: your gifts count only above 0.5% of your AGI, the usual percentage-of-AGI limits still apply (60% for cash to public charities, 30% for appreciated property), and if you are in the 37% bracket your itemized deductions are worth at most 35 cents on the dollar. The engine compares itemizing with the standard deduction and keeps whichever leaves less tax.
Bunching: giving two or three years’ worth in one year can lift that year above the standard deduction. A donor-advised fund lets you take the deduction now and pass the money to charities over the following years. The calculator shows the trade year by year. Not modelled here: carryovers of gifts above the AGI limits, gifts of appreciated stock (their capital-gain side), and state income tax, which treats gifts differently from state to state.
Common questions
- Can I deduct charitable donations in 2026 if I take the standard deduction?
- Yes, up to $1,000 of cash gifts ($2,000 on a joint return) to charities other than donor-advised funds and supporting organizations, on top of the standard deduction (IRC §170(p)). In the worked example that is $2,000, which is why a $12,000 gift still cuts their 2026 tax by $240.
- What is the new 0.5% floor on charitable deductions?
- From 2026, if you itemize, gifts count only to the extent they exceed 0.5% of your AGI (§170(b)(1)(I)). For the example couple that floor is $663.
- Does bunching donations into a donor-advised fund still save tax in 2026?
- It can: three years of gifts in one year may push your itemized deductions above the standard deduction once instead of never. In the example, $36,000 put into a donor-advised fund in 2026 makes that year’s deduction $58,338, and the couple pays $2,022 less federal tax over 2026–2028 than by giving $12,000 every year (2027 and 2028 PROJECTED under current law).
- Should I give from my IRA instead?
- From age 70½ a qualified charitable distribution from an IRA is left out of your income instead of deducted, so it helps whether or not you itemize and also lowers AGI. The QCD calculator compares it with a cash gift.
