A New Floor for Donors Who Itemize, and a New Deduction for Those Who Don't
Starting with the 2026 tax year, itemizers can deduct charitable gifts only above 0.5% of adjusted gross income, while non-itemizers can claim up to $2,000 in cash gifts.
American charitable giving is about to be reshaped by two provisions that pull in opposite directions, and nonprofits are still working out which effect will dominate.
For taxpayers who itemize, charitable contributions are now deductible only to the extent they exceed 0.5% of adjusted gross income. Corporations face a parallel floor of 1% of taxable income.
For taxpayers who do not itemize — the large majority, since the standard deduction was doubled in 2017 — a deduction of up to $2,000 for cash gifts to qualified charities is available.
Who gains and who loses
A household with $80,000 of income that gives $600 a year and takes the standard deduction now receives a deduction it did not have before.
A household with $500,000 of income that itemizes and gives $2,000 loses the deduction entirely, because the first $2,500 of giving falls below the floor.
A household with $500,000 of income that gives $50,000 is largely unaffected, losing the deduction on the first $2,500.
The bunching response
The floor's most predictable effect is to accelerate a strategy advisers have recommended since 2017: concentrating several years of giving into a single year to clear a threshold, then taking the standard deduction in the intervening years.
Donor-advised funds make this simple — contribute a lump sum in one year, take the deduction, and distribute grants to charities over time.
For nonprofits, that means more volatile revenue. A donor giving $5,000 every year becomes a donor giving $20,000 every four years, which is the same money and a very different cash flow.
What the evidence says about deductions and giving
Research on the responsiveness of giving to tax treatment is more mixed than either side of the debate usually acknowledges. Large gifts from high-income donors are quite tax-sensitive in timing and moderately sensitive in amount. Small gifts from ordinary households are driven far more by connection to the cause than by tax treatment.
That pattern suggests the new $2,000 deduction for non-itemizers will produce more paperwork than new giving, while the floor will mainly change when gifts are made rather than whether.
