Donor-Advised Funds: How They Work, When to Bunch, and DAF vs. QCD

It is a separately identified fund or account that a 501(c)(3) public charity maintains and operates, in which the donor keeps advisory privileges over grants and investments but the sponsor has legal control (IRS, updated June 2026). The tax code defines it the same way: an account identified with your contributions, owned and controlled by the sponsor, where you or someone you appoint expects to advise on distributions or investments because you are the donor (26 U.S.C. 4966(d)(2)).

Because the sponsor is itself a public charity, your contribution is a completed gift to charity on the day it arrives. You get the deduction then, even if the money waits years before reaching a food bank, a hospital or your college. That separation between the deduction and the grant is the whole point of the tool.

Sponsors come in three kinds: national charities affiliated with brokerage and investment firms, community foundations that serve a region, and single-issue or religious charities that run DAF programs, some of which require part of each account to go to their own work. All follow the same federal rules. They differ in fees, investment menus, minimums, the assets they accept, and their policies on successors and inactive accounts.

You open an account with a sponsor, name it, name your successors, and contribute. The sponsor sells any securities you give, invests the proceeds in the options you pick, and sends grants to the charities you recommend after checking that each is eligible.

The sponsor, not you, sends the grant, so the charity's thank-you letter will not serve as a tax receipt. Your receipt is the sponsor's acknowledgment of your contribution, which must state that the sponsor has exclusive legal control over the assets. Without that written acknowledgment, the deduction is not allowed (IRS Pub. 526; IRC 170(f)(18)).

Cash and publicly traded securities are accepted everywhere; most large sponsors also take mutual fund shares and, with review, more complex assets. What you give changes both the deduction and the tax you avoid.

The rules come from the tax code and IRS Publication 526: property held more than a year and given to a public charity is deductible at fair market value, while short-term property is deductible only at your basis; noncash gifts over $5,000 need a qualified appraisal and Section B of Form 8283, except publicly traded securities; digital assets are not publicly traded securities for this purpose (IRS Pub. 526).

Give your highest-gain shares. A lot bought for $20 that now trades at $200 saves far more tax than one bought at $180. Never give shares that have lost value: sell them, take the capital loss, and give the cash, as our tax-loss harvesting guide explains. One point the brochures leave out: if you are in your 70s and would hold a low-basis stock until death, your heirs would receive it with a stepped-up basis and the gain would never be taxed anyway. Giving it still makes sense if you would otherwise sell or rebalance; if you would not, the capital gains saving is smaller than it looks, and you might instead give the stock you plan to sell and leave the oldest lots to your heirs.

For gifts to a DAF, the same limits apply as for any public charity: cash up to 60% of adjusted gross income and appreciated long-term property up to 30%, with anything over the limit carried forward for 5 years (26 U.S.C. 170(b) and (d)). Three changes that took effect this year matter for anyone planning a large gift.

The 0.5% floor is small for one gift but adds up: at $150,000 of AGI it removes the first $750 of giving each year you itemize. Bunching reduces the cost, because you pay the floor once instead of every year. The 37% bracket cap matters only at the very top: it limits the value of each dollar of deduction to about 35 cents, so for the few readers with that much income, a deduction taken in a lower-bracket year may be worth almost as much.

The non-itemizer deduction cuts the other way. A couple who takes the standard deduction can now deduct up to $2,000 of cash given straight to charities each year, without the floor (IRC 170(p)). Grants from a DAF do not count, since you are not the donor at that point, and neither does the gift to the DAF itself. In a bunching plan, it is worth keeping $2,000 of direct cash gifts outside the fund in the standard-deduction years.

Bunching means making several years of gifts in one year, so that year's itemized deductions clear the standard deduction by a wide margin, and taking the standard deduction in the other years. A donor-advised fund makes it practical: you give once, and the charities still receive their usual gifts on their usual schedule.

Retirees need to give more than most people before itemizing helps at all. A married couple both 65 or older has a 2026 standard deduction of $35,500: the base $32,200 plus $1,650 each. A single filer 65 or older has $18,150. The separate senior deduction of up to $6,000 per person, available through 2028, applies whether or not you itemize, so it does not change the comparison. With a paid-off house, most retirees' only other itemized deduction is state and local tax.

Computed by My Finance Platform: standard deduction minus other itemized deductions, plus the 0.5% floor. Every dollar of giving above the figure shown reduces taxable income; below it, giving saves no federal income tax.

If you give less than the amount in the table every year, your gifts save nothing on your federal return. Bunching five years into one year turns most of them into deductions. Bunching pays best when the bunched year is also a high-income year, because the deduction then comes off income taxed at 24% or 32% instead of 12% or 22%. For retirees, that year is usually one with a large Roth conversion, a pension lump sum, a property or business sale, or the last year of salary.

Tom is 70 and turned 70½ in March; Ellen is 68. They file jointly. In an ordinary year their adjusted gross income is $160,000: two pensions, Social Security, $40,000 of withdrawals from Tom's IRA and some portfolio income. They pay $14,000 a year in state income and property tax and have no mortgage. They give $20,000 a year to their church, a food bank and Ellen's college. In 2026 they convert $200,000 of Tom's IRA to a Roth, as our guide to Roth conversions before RMDs describes, which raises their AGI to $360,000 and their state tax to $24,000. They own $100,000 of an index fund bought for $30,000.

They compare four ways to give the same $100,000 over five years:

• •A. Give cash each year. In 2026 the conversion pushes their state tax up enough that they itemize, but the gift only lifts their deductions from $35,500 to $42,200. In the other four years they take the standard deduction plus the new $2,000 non-itemizer deduction. Over five years their giving cuts federal tax by only $3,368.
• •B. Bunch five years of stock into a DAF in 2026. They give the $100,000 of shares to a DAF in 2026. The deduction is $100,000 less the $1,800 floor, well inside the 30% limit of $108,000, so their itemized deductions reach $122,200. That is $80,000 more than in option A, all of it off income taxed at 24%. From 2027 the DAF sends $20,000 a year to the same charities.
• •C. QCDs from Tom's IRA each year. Tom's IRA sends $20,000 a year directly to the charities. Nothing is deducted; instead, the gifts never enter AGI. It saves about as much as the DAF, and in the ordinary years it also keeps their AGI under the point where the senior deduction starts to shrink.
• •D. A QCD in 2026 plus four years of stock into a DAF. In 2026 Tom makes a $20,000 QCD for that year's gifts and they put $80,000 of shares into a DAF for the next four years.

The federal tax is close; the rest is not. Options B, C and D each save between $17,400 and $17,900 over five years compared with writing checks. The differences show up elsewhere. The QCD lowers AGI, and a deduction does not. Medicare premiums for 2028 are based on 2026 income, and at 2026 thresholds their AGI of $360,000 is above the $342,000 joint threshold for the next surcharge tier, while $340,000 is below it. Options C and D would save them about $3,500 in Part B and Part D surcharges that year (how IRMAA works). The DAF, meanwhile, moves $70,000 of unrealized gain out of their portfolio: $10,500 of tax at 15% if they would ever have sold those shares, nothing if they would have held them for their heirs. They can use the $20,000 a year of cash they no longer give away to buy the same fund again with a fresh basis.

Option D takes the best of both: the QCD keeps the conversion year's AGI below the IRMAA threshold, and the DAF captures a large deduction at 24%. The example also shows what would not work: Ellen cannot make QCDs until she turns 70½, Tom's QCDs must come from his own IRA, and no QCD can go into the DAF. Run your own brackets with the Tax Bracket Calculator before choosing.

Use a qualified charitable distribution first if you are 70½ or older, have an IRA and give to operating charities, and use a DAF for what a QCD cannot do. A QCD is a direct transfer from an IRA to a charity of up to $111,000 per IRA owner in 2026; it is excluded from income and, once you reach RMD age (73, or 75 if born in 1960 or later), counts toward your required minimum distribution. But the statute excludes donor-advised funds and supporting organizations as recipients, and the whole amount must be deductible, so nothing can come back to you (26 U.S.C. 408(d)(8)(B) and (C); IRS Notice 2025-67). Our QCD guide covers the mechanics.

Most readers in their 70s end up using both. QCDs cover the regular annual giving, which keeps AGI down and whittles the IRA before RMDs grow. The DAF is for years when you have highly appreciated stock to unload, a spike in income to offset, or gifts to make before you reach 70½. Check your required distribution with our RMD calculator to see how much of it QCDs could cover.

A DAF is the simplest and cheapest of the three. A private foundation gives you control, including over hiring and grants to individuals, at a cost in taxes, deductions and paperwork. A charitable remainder trust is the only one that pays you an income.

Sources: the foundation's 1.39% tax on net investment income is in IRC 4940; the payout rule rests on a 5% minimum investment return in IRC 4942(e); deduction limits and the cost-basis rule for non-public property are in IRC 170(b) and (e). A foundation makes sense for families giving several million dollars who want to employ family members, run programs or make scholarships. For most households, a DAF gives the same giving power at a fraction of the cost, and many families use both.

The two are not exclusive with a trust either. A charitable remainder trust can name a DAF as a remainder beneficiary in many cases, so the family keeps advising on grants after the trust ends. Ask the sponsor and the trust's attorney whether that works for your document.

One principle covers most of them: once the money is in the fund, neither you nor your family may get anything of value from it. The penalties fall on you as well as the sponsor.

If you want the gala table or the auction dinner, pay for it yourself and deduct only the part above the value you receive; do not send it through the DAF. Splitting the ticket does not fix it: in Notice 2017-73 the Treasury and IRS said that having the DAF pay the deductible part while you pay the rest relieves you of an obligation, which is a benefit that is more than incidental (IRS Notice 2017-73). Likewise, a grant that pays a grandchild's tuition or a membership you use is not allowed.

Expect two layers of cost: the sponsor's administrative fee, a percentage of the balance that falls as the account grows, and the expense ratios of the investments you pick. As one published example, Vanguard Charitable charges 0.60% on the first $500,000, 0.30% on the next $500,000 and 0.12% on the next $4 million, with fund expenses on top (Vanguard Charitable, September 2026). Other sponsors use similar tiered schedules; community foundations often charge more but offer local grant knowledge. We cite this only as an illustration, not a recommendation.

For a bunching plan in which the balance is spent within five years, the fee matters little: $100,000 granted out at $20,000 a year, at 0.6% a year on the balance, costs about $1,800 in total, ignoring growth. It matters more for a fund you intend to keep for decades or leave to your children.

A DAF is a simple way to keep a family giving together after you are gone. You name successor advisors, typically your spouse first, then your children, who take over recommending grants; or you name charities to receive the balance; or a mix. Sponsors differ on how many generations may advise and on what happens if you leave no instructions, so fill in the form when you open the account, not later.

Everything you contribute is already out of your estate. With a federal basic exclusion of $15,000,000 per person in 2026, few families give to a DAF to reduce estate tax, but a gift can still help in states with lower estate tax thresholds. Our estate planning basics guide and the Estate Planning Worksheet show where charitable accounts fit.

The strongest legacy move involves your IRA, not your will. A QCD cannot go to a DAF during your life, but you can name a DAF, or the sponsoring charity, as a beneficiary of a traditional IRA at death. The charity pays no income tax on the money, while a child inheriting the same IRA would owe tax on every dollar within ten years. Leave the IRA to charity and taxable brokerage assets, which receive a stepped-up basis, to your children. Our guide to gifting to children and grandchildren covers the lifetime side of that plan.

• •Giving cash while holding low-basis stock you plan to sell. Give the shares and use the cash to buy them back; the gain disappears and your basis resets.
• •Giving shares that have lost value. You lose the capital loss. Sell them, harvest the loss, and give the cash.
• •Giving shares held a year or less. The deduction drops to your cost.
• •Trying to send a QCD to your DAF. It is not a QCD; the distribution becomes taxable income.
• •Bunching in a low-income year. The deduction is worth the most in a year with high taxable income. Pair it with a Roth conversion, a sale or the last working year.
• •Ignoring the 30% limit. A large stock gift in a year of modest income may take up to 5 more years to deduct, and any excess after that is lost.
• •Paying for gala tickets or a pledge that came with benefits from the DAF. The 125% excise tax falls on you.
• •Missing the sponsor acknowledgment. Without it, the deduction fails. Keep it with your return.
• •Leaving no successor instructions. The sponsor then decides where the money goes.
• •Letting the fund sit. The deduction is for money meant for charity. Set a grant schedule and use it.
