Charitable Giving in 2026: Donor-Advised Funds, Bunching, and the New Math of Tax-Efficient Generosity

Our reading of the 2026 charitable provisions under the One Big Beautiful Bill Act draws on Michael Kitces’s analysis at Nerd’s Eye View; we’d recommend reading it in full.

Most people who give to charity get no tax benefit from it. That isn’t a criticism — it’s just arithmetic. The standard deduction has grown so large that the overwhelming majority of households take it rather than itemizing, and a charitable gift only reduces your taxes if it’s part of an itemized total that clears the standard deduction. For 2026, that wall sits at $16,100 for a single filer and $32,200 for a married couple filing jointly. If your mortgage interest, state and local taxes, and charitable gifts don’t add up past that, your generosity is real but your tax bill doesn’t notice.

For people who give consistently and meaningfully, this is a solvable problem — and solving it is one of the most satisfying pieces of planning we do, because it lets the same dollars do more. The household keeps giving exactly what it intended to give; it just gives in a structure that actually captures the deduction, avoids capital gains tax, and in some cases satisfies a required distribution at the same time. The generosity doesn’t change. The efficiency does.

This guide covers the full toolkit: the donor-advised fund as the central vehicle, the bunching strategy that makes the deduction work, why appreciated stock is usually the best thing to give, how qualified charitable distributions fit for those over 70½, and how the One Big Beautiful Bill Act reshaped the math starting in 2026. It’s written for the household that is already charitable and simply wants its giving to be as effective as its earning.

The core problem: the standard deduction wall

To understand why most charitable giving produces no tax benefit, you have to understand how the deduction actually works. Charitable contributions are an itemized deduction. You only benefit from itemized deductions to the extent that all of them added together exceed the standard deduction — the flat amount every taxpayer can subtract without itemizing at all.

When the Tax Cuts and Jobs Act roughly doubled the standard deduction in 2018, it pushed the vast majority of households below the itemizing threshold. Today only about one in ten taxpayers itemizes. For the other ninety percent, a $5,000 gift to charity and a $0 gift to charity produce exactly the same federal tax result, because neither household is itemizing in the first place. The deduction exists, but it sits unused on the other side of a wall most people never clear.

For a household that gives, say, $15,000 a year, this is genuinely frustrating. They’re giving real money, every year, and getting no tax recognition for it — because $15,000 of giving, even added to their state taxes and mortgage interest, doesn’t quite clear the $32,200 joint standard deduction. They’re close, but “close” gets you nothing. The deduction is all-or-nothing relative to the standard amount, and they keep landing on the wrong side of it.

The solution isn’t to give more or to give less. It’s to change when the deduction lands relative to when the giving happens. That’s what bunching and the donor-advised fund accomplish together.

The donor-advised fund, explained

A donor-advised fund (DAF) is the most useful charitable vehicle most people have never used. Mechanically, it’s a charitable account held at a sponsoring public charity — the charitable arms of the large custodians run the best-known ones, and community foundations sponsor others. You contribute money or assets to the account, and several things happen at once.

First, the contribution is irrevocable and complete the moment you make it. Once the money goes into the DAF, it is legally committed to charity — you cannot take it back. That irrevocability is precisely what makes it deductible: as far as the IRS is concerned, you have made a completed gift to a public charity.

Second, you take the full tax deduction in the year you contribute — not in the years the money eventually reaches the operating charities. This is the decoupling that makes everything else work. The deduction and the actual grants to charities happen on separate timelines.

Third, the assets are invested and grow tax-free inside the account. The money can sit and compound while you decide where it should go, and that growth is entirely free of tax because it already belongs to charity.

Fourth, you recommend grants to the charities you choose, on whatever schedule you like — this year, next year, spread over a decade. The sponsoring organization technically holds legal control and approves the grants, but in practice grant recommendations to legitimate public charities are honored as a matter of course.

The effect is that you separate the tax event (your contribution, deductible now) from the charitable event (the grants, made whenever you choose). You can take a large deduction in one year and continue supporting your church, your alma mater, and your local food bank at exactly the same annual pace you always have. The charities don’t see any change. Your tax return does.

A DAF is not the same as a private foundation. A foundation is a separate legal entity with its own filing requirements, a mandatory annual payout, excise taxes, and meaningful administrative cost — it makes sense at much larger scale and where the family wants formal control. A DAF delivers most of the practical benefit — the upfront deduction, the tax-free growth, the legacy continuity — with almost none of the overhead, and with better deduction limits, as we’ll see. For the great majority of charitable households, the DAF is the right tool.

Bunching: the strategy that makes the deduction work

Bunching is the spine of tax-efficient giving, and the DAF is what makes bunching practical.

The idea is straightforward. Instead of giving $15,000 every year — and never clearing the standard deduction — you concentrate several years of giving into a single year. You contribute, say, $60,000 to a donor-advised fund in one year (four years of giving at once), itemize that year because the large contribution easily clears the standard deduction, then take the standard deduction in the three “off” years when you make no new charitable contributions. Meanwhile, you grant the $60,000 out of the DAF to your usual charities at your usual $15,000-a-year pace, so the charities experience no change at all.

The math is the entire point. By spreading $15,000 a year evenly, that household clears the standard deduction in no year and captures no charitable deduction ever. By bunching $60,000 into one year, it itemizes in that year — capturing a deduction for the charitable gift plus the state taxes and mortgage interest it can only use in an itemizing year — and still takes the full standard deduction in the other three. Same total giving, same charities, same pace of support. One household captures a four-year charitable deduction; the other captures nothing. The only difference is timing.

The donor-advised fund is what makes this humane rather than chaotic. Without a DAF, bunching would mean dumping four years of donations on your charities in a single year and then going silent for three — disruptive for them and for you. The DAF absorbs the lump sum, lets it grow, and meters it out steadily. You get the concentrated deduction; the charities get their steady support. That decoupling is the whole trick.

Bunching is most powerful for the household sitting just below the itemizing threshold — close enough that a concentrated gift vaults them well over it. The further below the wall a household’s annual giving leaves them, the more a bunched contribution changes the picture.

Appreciated stock: usually the best thing to give

Here is the single most underused move in charitable giving: for most people, the best asset to give is not cash. It’s long-term appreciated stock — and giving it through a DAF captures a double benefit that writing a check can never match.

When you donate stock you’ve held more than a year and that has risen in value, two things happen. First, you deduct the full fair market value of the stock — not what you paid for it, but what it’s worth today. Second, you never pay capital gains tax on the appreciation. The gain simply vanishes from your tax life. The charity, as a tax-exempt entity, sells the stock and pays no tax on the gain either. The appreciation that would have cost you capital gains tax had you sold it yourself is given, in full, to charity.

Consider stock you bought years ago for $10,000 that’s now worth $50,000. If you sold it, you’d owe long-term capital gains tax on the $40,000 gain — at the 15% or 20% federal rate, plus possibly the 3.8% net investment income tax, plus state tax. If instead you contribute the shares directly to your DAF, you deduct the full $50,000, you owe no capital gains tax on the $40,000, and the charity ultimately receives the full $50,000. You’ve given more and kept more, simultaneously, compared to selling the stock and donating the after-tax cash.

This pairs naturally with a broader portfolio concern. Households that have held investments for a long time often end up with a concentrated, low-basis position — a single stock that has grown to dominate the portfolio and that they’re reluctant to trim precisely because the embedded gain would trigger a large tax bill. Charitable giving turns that problem into an opportunity: the most-appreciated, lowest-basis shares are exactly the ones you want to give, because they carry the largest unrealized gain you get to avoid. Giving from a concentrated position lets you reduce the position, capture the deduction, and skip the gain all at once. (We go deeper on managing concentrated positions in our piece on concentrated stock and diversification.)

One rule to know: the deduction for appreciated property given to a public charity (including a DAF) is limited to 30% of your adjusted gross income in the year of the gift, versus 60% of AGI for cash. Anything above the limit isn’t lost — it carries forward for up to five years. For very large gifts this matters for timing; for most gifts it doesn’t bind at all.

Qualified charitable distributions: the tool for the 70½ crowd

If you’re 70½ or older and have a traditional IRA, you have access to a charitable tool that’s even cleaner than a deduction: the qualified charitable distribution (QCD).

A QCD lets you send money directly from your IRA to a qualified charity — up to $111,000 per person in 2026 — and that amount is excluded from your income entirely. It isn’t a deduction; it’s an exclusion, which is better. A deduction reduces your taxable income after your adjusted gross income is calculated. A QCD keeps the money out of AGI in the first place, which means it also keeps down everything that AGI drives: the taxation of your Social Security, your Medicare IRMAA surcharges, and the various income-based thresholds that quietly raise your effective tax rate in retirement. And once you reach RMD age, a QCD counts toward your required minimum distribution — satisfying a distribution you’d otherwise be taxed on, without the income ever landing on your return.

The QCD and the DAF serve different people and, importantly, do not combine: the tax law specifically prohibits using a QCD to fund a donor-advised fund. A QCD must go to an operating charity directly. So the two tools occupy different lanes. For a retiree over 70½ giving from an IRA, the QCD is often the most efficient possible gift. For a pre-retiree, a high-income earner, or anyone giving appreciated stock, the DAF-and-bunching approach is the workhorse. Many households eventually use both — the DAF during the high-earning years, the QCD once the IRA and age line up. We cover the QCD mechanics in full, including how it coordinates with required distributions, in our guide to required minimum distributions in 2026.

What the One Big Beautiful Bill Act changed for 2026

The OBBBA, signed in July 2025, kept the basic architecture of the charitable deduction but added three wrinkles that take effect in 2026 — and each one, in its own way, strengthens the case for the DAF-and-bunching approach rather than weakening it.

A new 0.5%-of-AGI floor on itemized charitable deductions

Beginning in 2026, an itemizer can deduct charitable contributions only to the extent they exceed 0.5% of adjusted gross income. The first half-percent of your AGI in giving is simply not deductible. For a household with $300,000 of AGI, the first $1,500 of charitable giving no longer counts; only giving above that threshold is deductible. For a household at $200,000 of AGI, the floor is $1,000.

On its face this is a modest haircut, but it does something important to strategy: it penalizes thin, spread-out giving and rewards concentration. A household that gives a little every year now loses the first slice of every year’s gift to the floor. A household that bunches gives once, clears the floor once, and loses the slice only that single time instead of annually. The floor, in other words, makes bunching more valuable than it already was — concentrating the giving means you only pay the floor’s toll once.

The DAF interacts with the floor in exactly the way you’d want. Making one large contribution to a DAF in a single year clears the 0.5% floor that year and captures the full deduction above it; you then grant out of the DAF over the following years, supporting your charities at your normal pace, without those smaller annual grants having to clear the floor again — because the grants aren’t new contributions, they’re distributions of money you already gave and already deducted. One contribution, one encounter with the floor, years of steady giving on the other side of it.

A useful technical note: amounts you contribute above the AGI percentage limits carry forward for up to five years, and charitable carryforwards from years before 2026 are not subject to the new floor. The floor applies to current-year contributions, not to deductions you’re carrying in from prior years.

A cap on deduction value for top-bracket donors

The second change affects high earners specifically. For taxpayers in the top 37% bracket — those with taxable income above $640,600 single or $768,700 married filing jointly in 2026 — the value of itemized deductions is now limited so that they save at most 35 cents on the dollar rather than the 37 cents their top marginal rate would otherwise deliver. Mechanically, the law reduces the allowable deduction by 2/37 of the amount sitting in the top bracket, which nets out to a 35% benefit on those deductions. In practical terms, a $10,000 deduction that used to be worth $3,700 to a top-bracket donor is now worth $3,500.

This is a limitation on the value of all itemized deductions for top earners, not a charitable-specific rule, and the effect on any individual gift is modest. But for a donor who knows they’ll be in the top bracket for years, it slightly raises the after-tax cost of giving and rewards thoughtful timing: concentrating deductions into a year when income is not at the very top of the bracket, where possible, preserves more of their value. It’s a reason to plan the timing of large gifts deliberately rather than defaulting to “a bit each year.”

A new deduction for non-itemizers

The third change cuts the other way — it’s a genuine expansion. Starting in 2026, taxpayers who take the standard deduction can also deduct up to $1,000 (single) or $2,000 (married filing jointly) of cash gifts to qualifying charities. For the ninety percent of households that don’t itemize, this is the first charitable tax benefit they’ve had since a small, temporary version expired after 2021.

Two limits matter. The gift must be cash — not appreciated stock — and it cannot go to a donor-advised fund. It has to go to an operating charity directly. So this is a tool for the non-itemizing household giving modest amounts directly to charities they support, not a DAF strategy. It’s worth maxing out if you’re in that situation, but it sits alongside the bunching approach rather than replacing it. (The deduction is also not indexed for inflation, so its real value will erode over time.)

The throughline across all three changes: the new rules reward concentration, deliberate timing, and giving appreciated assets through a vehicle that lets you clear the floor once and grant steadily afterward. That is precisely what a donor-advised fund, used with a bunching strategy, is built to do.

Giving from a business or before a liquidity event

For business owners and anyone approaching a large taxable event, charitable timing becomes a much bigger lever — because the value of a deduction is highest in your highest-income years.

The principle is simple: a charitable deduction is worth more when it offsets income taxed at a high rate. A year with an unusually large income spike — the sale of a business, a major Roth conversion, the exercise of equity compensation, the recognition of a large capital gain — is exactly the year a concentrated charitable contribution does the most work. Funding several years of intended giving into a DAF in that single high-income year captures the deduction at the highest possible rate and offsets income you’d otherwise be taxed heavily on, while still letting you grant the money out gradually for years afterward.

The asset you give in that situation matters too. An owner anticipating the sale of a company can, with careful and advance planning, contribute a portion of the business interest itself to a DAF or charity before the sale closes — giving the appreciated asset rather than the after-tax cash, and avoiding capital gains tax on the donated portion. The timing and mechanics here are genuinely technical and have to be handled before a sale is under a binding agreement, but the payoff for the right situation is substantial. This is the kind of move that belongs in a coordinated plan well ahead of a transaction, not a year-end scramble.

The same logic applies to the concentrated, low-basis public stock discussed earlier. If you know a high-income year is coming, pre-funding a DAF with appreciated shares in that year stacks three benefits at once: a deduction at your highest marginal rate, complete avoidance of the capital gain on the donated shares, and a reduction in a concentrated position you wanted to trim anyway.

Choosing the funding asset: a decision framework

Once you’ve decided to give efficiently, the remaining question is what to give. The asset you choose changes the tax result more than almost any other decision, and the right answer depends on what you hold and how old you are.

As a general hierarchy: long-term appreciated stock is usually the best asset to give, because it captures a deduction at full fair market value and avoids the capital gains tax — a benefit cash can’t replicate. For donors over 70½ giving from an IRA, a QCD is often even better, because it keeps the gift out of AGI entirely and can satisfy a required distribution. Cash is the simplest and enjoys the highest AGI limit (60%), which makes it useful for very large single-year gifts or for clearing the floor, but it’s the least tax-efficient per dollar because it carries no embedded gain to avoid. And for the non-itemizing household giving modest amounts, direct cash gifts up to the new $1,000/$2,000 non-itemizer deduction are the right tool, since those can’t run through a DAF anyway.

In practice, the most efficient plans often combine assets: appreciated stock to a DAF to capture the deduction and dodge the gain, sometimes paired with cash in the same year to take advantage of the higher cash AGI limit, with QCDs layered in once age allows. The point isn’t to use every tool — it’s to match the asset to the household’s holdings, income, and age so that the same generosity carries the lowest possible tax cost.

Bringing it together

Tax-efficient charitable giving doesn’t ask you to give more or give less. It asks you to give the same amount through a structure that actually works. For most charitable households, that structure is a donor-advised fund funded by bunched contributions of appreciated stock — clearing the standard deduction and the new 0.5% floor in a concentrated year, avoiding capital gains tax on the appreciation, and granting out to the charities you love at the steady pace you always intended. For those over 70½, the qualified charitable distribution adds a second, even cleaner lane. And for the high-income year — a business sale, a large conversion, an equity event — concentrated giving captures a deduction at its highest possible value.

The OBBBA’s 2026 changes don’t undermine any of this. The 0.5% floor and the top-bracket cap reward exactly the concentration and deliberate timing that a DAF-and-bunching strategy is built around, and the new non-itemizer deduction extends a small benefit to everyone else. The household that plans its giving keeps more of its money working toward the causes it cares about; the household that gives on autopilot leaves a real deduction on the table year after year.

That gap — between intentional giving and automatic giving — is entirely a planning question, and it’s one of the most rewarding to solve, because nobody has to give up anything to capture it. The generosity stays exactly the same. Only the efficiency improves. That’s the distinction we draw in our work on what a tax strategist actually does: not changing what you want to do with your money, but making sure the structure around it doesn’t quietly cost you more than it should.

Common Questions About Charitable Giving and DAFs

What is a donor-advised fund? A donor-advised fund is a charitable account held at a sponsoring public charity. You contribute cash or assets, take an immediate tax deduction, let the money grow tax-free inside the account, and then recommend grants to the charities you choose over time. It separates the tax deduction (which happens when you contribute) from the actual giving (which happens whenever you grant the money out), making it the central vehicle for tax-efficient charitable planning.

Why doesn’t my annual charitable giving reduce my taxes? Charitable contributions are an itemized deduction, so they only reduce your taxes if all your itemized deductions together exceed the standard deduction — $16,100 for single filers and $32,200 for married couples filing jointly in 2026. About 90% of households don’t clear that threshold, so their giving produces no federal tax benefit. Bunching multiple years of giving into one year through a donor-advised fund is the most common way to solve this.

What is charitable bunching? Bunching means concentrating several years of charitable giving into a single tax year — typically by making one large contribution to a donor-advised fund — so that you clear the standard deduction and itemize in that year, then take the standard deduction in the off years. You grant the money out of the DAF to your charities at your normal pace, so they see no change. Same total giving, but you capture a deduction you’d otherwise miss entirely.

Should I donate cash or appreciated stock? For most people, long-term appreciated stock is the better gift. When you donate stock held more than a year, you deduct its full fair market value and never pay capital gains tax on the appreciation. Donating $50,000 of stock you bought for $10,000 lets you deduct the full $50,000 and avoid tax on the $40,000 gain entirely. Cash has a higher AGI deduction limit (60% versus 30% for appreciated property), which matters for very large gifts, but per dollar it’s less tax-efficient because it carries no gain to avoid.

How did the One Big Beautiful Bill Act change charitable giving in 2026? Three changes took effect in 2026. Itemizers can now only deduct charitable gifts that exceed 0.5% of their adjusted gross income (a new floor). Top-bracket (37%) donors have the value of their itemized deductions capped at 35 cents on the dollar. And non-itemizers can now deduct up to $1,000 (single) or $2,000 (married filing jointly) of cash gifts to operating charities — but not to a donor-advised fund. The floor in particular makes bunching more valuable, because concentrating your giving means you only clear the floor once.

Can I use a qualified charitable distribution to fund a donor-advised fund? No. The tax law specifically prohibits using a QCD to fund a donor-advised fund. A qualified charitable distribution must go directly to an operating charity. QCDs (available at 70½ and up, limited to $111,000 per person in 2026) and DAFs serve different roles — the QCD keeps the gift out of your AGI and can satisfy a required minimum distribution, while the DAF captures an upfront deduction and lets you grant over time. Many households use both at different stages.

Is a donor-advised fund better than a private foundation? For most charitable households, yes. A DAF delivers the upfront deduction, tax-free growth, and the ability to involve family across generations, with almost none of the administrative cost, mandatory annual payout, or excise taxes a private foundation carries. A DAF also offers better deduction limits — up to 60% of AGI for cash and 30% for appreciated stock, versus 30% and 20% for a private foundation. A private foundation makes sense at much larger scale or where the family wants formal legal control, but the DAF is the right tool for the great majority.
