A Give-and-Take on Giving
The One Big Beautiful Bill did something unusual to charitable deductions: it handed a benefit to most Americans and quietly clawed one back from the people who give the most. Both changes start with the 2026 tax year, and if you don't know which side of the line you're on, you could plan your year-end giving exactly wrong.
The headline most people will hear is the cheerful one — non-itemizers can deduct charitable gifts again, for the first time since the pandemic-era break expired. The headline most accountants are worried about is the other one — itemizers now lose the first 0.5% of their AGI in giving, and top-bracket donors take a further trim on top of that.
So whether 2026 is good or bad for your charitable deduction depends almost entirely on whether you itemize. Here's both halves.
§ 01The 0.5% Floor, Explained
Here's the new rule for itemizers, stated plainly: you can only deduct charitable contributions to the extent they exceed 0.5% of your AGI. The first half a percent of your income that you give away is no longer deductible. It's a floor, the same way the medical expense deduction has long had a 7.5% floor.
The arithmetic is simple. Take your AGI, multiply by 0.5%, and that's the slice of giving that doesn't count:
| AGI | 0.5% floor | First dollars that don't count |
|---|---|---|
| $100,000 | $500 | First $500 of gifts |
| $200,000 | $1,000 | First $1,000 of gifts |
| $500,000 | $2,500 | First $2,500 of gifts |
| $1,000,000 | $5,000 | First $5,000 of gifts |
If you give a lot relative to your income, the floor is a rounding error — losing the first $2,500 on $80,000 of annual giving barely registers. Where it stings is the moderate, consistent giver: the household on $200,000 AGI that gives $3,000 a year now only deducts $2,000 of it. A third of their deduction, gone, not because they gave less but because the rules changed underneath them.
§ 02The 35% Cap for Top-Bracket Donors
There's a second, separate trim aimed squarely at the highest earners. For taxpayers in the top 37% bracket, the OBBBA caps the value of itemized deductions — charitable gifts included — at 35 cents per dollar rather than the full 37.
What that means in practice: a top-bracket donor making a $100,000 deductible gift used to save $37,000 in tax. Under the cap, the same gift saves $35,000. The deduction still happens — it's just worth two cents on the dollar less than the donor's actual marginal rate.
It stacks with the floor, too. A wealthy donor first loses the 0.5%-of-AGI slice, then has the remaining deduction valued at 35% instead of 37%. Neither change is dramatic on its own. Together they signal a direction: the federal subsidy for large charitable gifts is being gently dialed back.
§ 03The Good News: Non-Itemizers Get a Deduction Back
Now the cheerful half. Since the Tax Cuts and Jobs Act roughly doubled the standard deduction in 2018, the overwhelming majority of Americans — around 90% — take the standard deduction and get no tax benefit from charitable giving at all. A brief above-the-line break existed in 2020 and 2021, then vanished.
From 2026, it's back and permanent. Taxpayers who take the standard deduction can deduct cash charitable contributions of up to $1,000 (single) or $2,000 (married filing jointly) above the line — meaning it comes off before AGI is calculated, which can have knock-on benefits for other AGI-linked thresholds.
Two conditions worth noting: it's for cash gifts (not donated goods or stock), and the 0.5% floor that hits itemizers does not apply here. For the 90% of filers who take the standard deduction, this is a genuine, no-strings improvement — modest in dollars, but real.
§ 04Three Worked Examples
The standard-deduction household. A married couple, $90,000 AGI, takes the standard deduction and gives $1,500 to their church in cash. In 2025 they deducted $0 from giving. In 2026 they deduct $1,500 above the line — capped at $2,000, so the whole gift counts. Pure gain.
The moderate itemizer. A single filer, $200,000 AGI, itemizes (big mortgage, high SALT) and gives $3,000. The 0.5% floor is $1,000, so only $2,000 is deductible. They lose a third of their charitable deduction versus the old rules — a clear loss.
The major donor. A top-bracket couple, $2,000,000 AGI, gives $200,000. The floor knocks out the first $10,000 (0.5% of AGI), leaving $190,000 deductible — then valued at 35% rather than 37%, worth $66,500 in tax savings instead of the $70,300 the full rate on $190,000 would imply. A meaningful but proportionally small haircut on a large gift.
§ 05Bunching and Donor-Advised Funds
The floor changes the math on a strategy that was already popular: bunching. Because the 0.5% floor is an annual hit, spreading your giving evenly across years means you eat the floor every single year. Concentrating several years of donations into one year means you only cross the floor once.
Say you'd normally give $4,000 a year on a $200,000 AGI. Spread out, you lose $1,000 to the floor annually — $3,000 deductible each year. Bunch three years of giving ($12,000) into one year, and you still only lose $1,000 to the floor that year — $11,000 deductible — while taking the standard deduction in the two off years.
A donor-advised fund (DAF) is the usual vehicle for this: you contribute a lump sum in the bunching year, take the deduction up front, then dole the money out to charities over the following years on your own schedule. The OBBBA's floor makes the timing benefit of a DAF more valuable than it was, precisely because it punishes thin, every-year giving.
For the broader 2026 deduction picture, see the 2026 standard deduction guide (which sets the itemize-or-not decision) and the SALT cap jump to $40,400 — the change most likely to push you into itemizing in the first place. Run your own numbers on the US calculator.
§ 06Key Takeaways
- From 2026, itemizers face a 0.5%-of-AGI floor on charitable deductions — the first half a percent of income you give away no longer counts.
- Top-bracket (37%) donors also have the value of itemized deductions, charitable included, capped at 35 cents per dollar.
- Non-itemizers gain a new above-the-line deduction of up to $1,000 (single) / $2,000 (MFJ) for cash gifts — and it's not subject to the floor.
- The floor hits moderate, consistent itemized givers hardest — those whose annual giving is only modestly above the floor.
- Bunching and donor-advised funds grow more valuable: cross the annual floor once instead of every year.
- Non-itemizer deduction is cash-only — donated goods and appreciated stock don't qualify for that $1,000/$2,000 break.
