The latest filing data from the IRS Statistics of Income division reveals a baseline that should get the attention of donors and non-profit executives alike: roughly 85% to 90% of American households still claim the standard deduction.
Itemizing on Schedule A remains off the table for the vast majority of taxpayers.
It is a reality that both the Association of Fundraising Professionals (AFP) and the National Council of Nonprofits have highlighted as development teams scramble to balance year-end budgets. But for 2026, the math split into two distinct realities and introduced an income phaseout curve that may catch many high-earning households off guard.
With the state and local tax (SALT) deduction cap expanded to $40,400 for 2026, donors have bifurcated into two separate worlds. And if non-profit leaders send the same one-size-fits-all appeal to everybody, they are leaving substantial impact and critical operating capital on the table, as well as potentially confusing and alienating donors.
The Tale of Two Donor Bases
Camp 1: The New Itemizers (and the $505k Phaseout Reality).
Take a married couple living in a high-tax state like California or New York. Between state income taxes and property taxes, they might pay $28,000. Under the old $10,000 SALT ceiling, they were trapped well below the $32,200 joint standard deduction. Today, with the $40,400 cap, their full $28,000 is deductible. Add $12,000 in mortgage interest, and their baseline itemized deductions total $40,000.
They reach the standard deduction hurdle before writing a single charitable check. For this group, every dollar given in December produces immediate tax relief on Schedule A.
The catch? The high-income gradient (further reading).
The full $40,400 SALT deduction starts phasing out once modified adjusted gross income (MAGI) exceeds $505,000. For every dollar over that threshold, the deduction shrinks by 30 cents, dropping all the way back to the old $10,000 floor for earnings of about $606,333 and above.
If a household lands in that phaseout zone, their baseline deductions compress rapidly. A family earning $575,000 loses over $20,000 of their SALT write-off, suddenly landing them right back near the standard deduction fence. For these high-income donors, knowing their exact MAGI before December 31 is the difference between writing off their giving and absorbing it entirely.
Camp 2: The Standard Deduction Majority.
Now look at the couple with a paid-off mortgage, living in a state with modest property taxes, or living in a house they’ve been in for 30 years in a state like California where Prop 13 keeps their property taxes low. Their combined SALT and deductions might sit at $20,000. If they write a $5,000 check to their local food bank in December, their total itemized deductions reach $25,000.
Frustratingly, they are still $7,200 below the $32,200 threshold. From a tax perspective, that $5,000 gift generated exactly zero deduction. They did a wonderful thing for their community, but the tax code completely ignored it.
Enter the DAF Bunch: Doing More on Purpose
For households under the line or high earners who got pushed back under it by the phaseout, writing annual checks from a personal checking account is the most inefficient way to give.
This is where Donor-Advised Fund (DAF) “bunching” comes in. Instead of writing a $5,000 check every December, our couple combines three years of intended giving into one: a single $15,000 contribution into a DAF in Year 1.
Look at what happens to Year 1:
$20,000 baseline deductions + $15,000 charitable contribution = $35,000 in itemized deductions. They cross the $32,200 threshold, unlocking tax deductions they would have completely lost otherwise. In Years 2 and 3, they simply revert to taking the full standard deduction.
How Non-Profit Leaders Must Pivot in Q4
If you lead a non-profit, here’s your opportunity to evolve away from sending generic “please give before December 31” form letters. Donors do not need another emotional plea; they need a partner who understands the math.
Segment your outreach into two targeted conversations:
For donors above the threshold (under $505k MAGI): “Your gifts are 100% tax-deductible again—now is the year to lean in.” Remind high-capacity donors in high-tax regions that the $40,400 SALT cap has restored full deductibility to their charitable gifts, provided their income hasn’t triggered the phaseout.
For donors below the threshold (or phased out above $606k): Educate supporters on how bundling multi-year gifts into a DAF bridges the standard deduction gap without requiring them to change their annual support cadence.
Steward the off-years: When a DAF grant arrives in Year 2, do not send a generic tax receipt—they already took their tax deduction back in Year 1. Send an impact report. Pick up the phone. Treat them as strategic investors whose multi-year vision provides your organization with predictable operating runway.
Generosity should come with as little financial friction as possible. When donors use smart math to expand their capacity, and non-profits step up as strategic partners rather than passive recipients, everyone wins.
