Bunching charitable donations went from a nice idea to a necessary one in 2026, because the tax code now takes a bite out of the front of every gift you make. If you itemize, the first 0.5% of your adjusted gross income in charitable contributions produces no deduction at all.
On $500,000 of income, that is the first $2,500. Give exactly $2,500 to your church and you deduct nothing.
Three other changes landed at the same time, and together they hit larger donors hardest. Here is what changed, how bunching answers it, and why a Tucson retiree over 70½ should probably do something else entirely.
What Is Charitable Bunching and How Does It Work
Charitable bunching means concentrating two, three, or more years of planned giving into a single tax year instead of spreading it evenly. The charity gets the same money. You just change when it arrives.
The logic used to be about the standard deduction. If your itemized deductions fell short of the standard deduction most years, bunching pushed you over the line in one year and you took the standard deduction in the others.
The new floor adds a second reason. You pay that 0.5% toll once per year you give, so giving in fewer years means paying it fewer times.
What Are the New Rules for Charitable Giving in 2026
Four changes took effect for tax years beginning in 2026, all from the One Big Beautiful Bill Act.
The 0.5% Floor for Itemizers
Itemizers deduct only the portion of their charitable gifts that exceeds 0.5% of adjusted gross income. Every dollar below that line is non-deductible, no matter how much you give above it.
A married couple with $400,000 of AGI who gives $5,000 loses the first $2,000 and deducts $3,000.
The 35% Cap for Top-Bracket Taxpayers
Taxpayers in the 37% bracket now receive a 35% benefit on all itemized deductions, charitable gifts included. A $10,000 deduction that saved $3,700 in tax now saves $3,500.
The cap applies to every itemized deduction, so state and local taxes, medical expenses, and investment interest all shrink alongside your charitable deduction.
A New Deduction for Non-Itemizers
People who take the standard deduction can now deduct up to $1,000 in cash gifts, or $2,000 for married couples filing jointly. This one is above the line, so the 0.5% floor does not apply to it.
There is a significant exclusion. Gifts to donor-advised funds, supporting organizations, and private foundations do not qualify.
Two Rules That Did Not Change
The 60% of AGI limit on cash gifts to public charities became permanent rather than expiring. Corporations picked up their own floor at 1% of taxable income.
A Worked Example of Bunching Charitable Donations
Take a Tucson couple with $300,000 of AGI who give $12,000 a year to causes they support. Their floor is $1,500.
Giving annually. Each year they deduct $12,000 minus $1,500, which is $10,500. Across three years that totals $31,500.
Bunching into one year. They give $36,000 in year one and nothing in years two and three. The floor still costs them $1,500 once, so they deduct $34,500.
The difference is $3,000, which is exactly the two floors they skipped. Same money to the same charities, three thousand dollars more in deductions.
That figure isolates the floor by itself. Whether you also come out ahead on the standard deduction in the off years depends on your property taxes, your mortgage interest, and the rest of your itemized picture, which is a conversation for your CPA rather than a calculator.
How Much Can You Deduct for Charitable Contributions in 2026 Without Itemizing
Up to $1,000 for a single filer and $2,000 for a married couple filing jointly, in cash gifts to qualifying public charities. Roughly nine in ten households take the standard deduction, so this restores a tax benefit that most givers lost after 2017.
It is modest, and it comes with the donor-advised fund exclusion above. If you take the standard deduction and route your giving through a DAF, that money earns you nothing on the return.
Notice what those two provisions do together. The floor pushes itemizers toward bunching, and bunching usually means opening a donor-advised fund. The new deduction rewards everyone else, and shuts DAFs out of it.
Who Should Skip Bunching Entirely
If you are 70½ or older with a traditional IRA, a qualified charitable distribution beats bunching in almost every case, and it is the single most useful thing on this page.
A QCD sends money straight from your IRA custodian to the charity. The distribution never enters your adjusted gross income. Because it is an exclusion rather than a deduction, the 0.5% floor does not touch it, the 35% cap does not touch it, and it works whether you itemize or not.
For 2026 the annual limit is $111,000 per person, so a married couple with separate IRAs can move $222,000. The IRS sets out the mechanics in Publication 590-B, including the requirement that the money go directly from the custodian to the charity.
Three details worth knowing:
- It counts toward your required minimum distribution. You satisfy the RMD and keep the income off your return in one move.
- You cannot deduct it as well. The exclusion replaces the deduction rather than stacking on top of it.
- Lower AGI reaches further than the charitable line. Adjusted gross income drives how much of your Social Security is taxable and which Medicare premium tier you land in two years later. Our guide to Is Social Security Taxed in Arizona covers that interaction.
QCDs are not available for gifts to donor-advised funds or private foundations, which is the same exclusion the non-itemizer deduction carries.
The One-Time Election Most People Have Never Heard Of
SECURE 2.0 created a once-per-lifetime election allowing a QCD to fund a split-interest vehicle: a charitable remainder annuity trust, a charitable remainder unitrust, or a charitable gift annuity. For 2026 the limit is $55,000, up from $54,000 in 2025.
That amount counts inside the $111,000 annual cap rather than on top of it, and several published summaries state this incorrectly.
The appeal is that it produces income. You move IRA money out of your estate and out of your AGI, the charity receives the gift, and you receive fixed payments for life. Publication 590-B specifies that a gift annuity funded this way must begin making fixed payments of 5% or greater within one year of funding. The election also requires a statement attached to your return, and it can only be used once, so the timing matters more than most decisions in this area.
That structure is what our Charitable Gift Annuities work involves for families across Tucson, Oro Valley, and Marana, coordinated with the CPA who files the return.
What This Means for Arizona Donors
Arizona taxes income at a flat 2.5%, so the state-level math on a charitable gift looks different here than it does in a progressive-rate state. The federal changes described above do the heavy lifting either way.
Arizona also offers its own tax credits for gifts to qualifying charitable organizations, foster care organizations, and public schools. Credits work differently from deductions and they are unaffected by the federal floor, so they are worth raising with your CPA separately rather than folding into the bunching decision.
Frequently Asked Questions
Does the 0.5% Floor Apply If I Take the Standard Deduction
No. The floor applies only to itemizers. The above-the-line deduction for non-itemizers is capped at $1,000 or $2,000 and sits outside it.
Can I Bunch Using Appreciated Stock Instead of Cash
Yes, and donating appreciated securities held more than a year avoids the capital gains tax you would owe on a sale. The AGI percentage limits differ for non-cash gifts, so the amount you can deduct in a single year is lower.
What Happens to Donations Above the AGI Limits
Contributions that exceed the annual percentage limits generally carry forward for up to five years. Carried-forward amounts fall under the rules in effect when you use them.
Is a Donor-Advised Fund Still Worth Using
For itemizers who bunch, often yes, because a DAF lets you take the deduction in the year you fund it while granting the money out over time. For anyone taking the standard deduction or making a QCD, a DAF is specifically excluded.
When Should I Decide
Before the year closes. Both bunching and a QCD are timing decisions, and neither can be applied retroactively once December 31 passes.
How We Coordinate Charitable Giving at Global Investment Strategies
Your CPA calculates what a gift does to your return. We work the layer above that: how much to give, in which year, from which account, and through which structure.
In practice that means comparing a bunched gift against a QCD against a gift annuity for your specific income, checking whether a one-time election is worth using now or holding, and confirming the vehicle you choose still fits the estate plan your attorney drafted. When the numbers turn on a filing question, we take it back to your CPA rather than guessing.
We have coordinated planning for Tucson families since 2009. For donors also weighing conversions, the AGI lever works from both directions, and our guide to Roth Conversion Before RMDs covers the other side of it.
Decide Before December
If you give regularly and you have not looked at your giving since 2025, the floor is worth twenty minutes. Pull your AGI, multiply by 0.005, and see what that number costs you at your current giving pace.
We work with families across Tucson, Oro Valley, Marana, Catalina Foothills, and Sahuarita. Request a private conversation and we will walk through what your giving produces this year against what it could produce, alongside your CPA.
