6 Questions to Ask Before You Open a Donor-Advised Fund
Sam's List Editorial | 2026-07-28
If you give to charity every year and you itemize, 2026 changed your math. Starting this year, the first 0.5 percent of your adjusted gross income given to charity produces no itemized deduction at all. Only what you give above that line counts.
On 400,000 dollars of AGI, that is 2,000 dollars of giving that is now deduction-free. Give 6,000 dollars and you deduct 4,000. Give exactly 2,000 and you deduct nothing.
That single change is why donor-advised funds are suddenly a mainstream conversation rather than a niche one, and it is also why opening one on autopilot is a mistake. These are the donor-advised fund questions worth working through first, with the trade-off attached to each.
1. Does the New AGI Floor Actually Change What I Should Do?
A donor-advised fund lets you make one large contribution now, take the deduction now, and recommend grants to charities over the following years. The strategic use in 2026 is straightforward: concentrate several years of intended giving into a single year so the total clears the 0.5 percent floor with room to spare, then let the grants trickle out on your normal schedule.
Run your own numbers before you assume it helps. If you already give well above 0.5 percent of AGI every year, the floor takes a modest bite and bunching buys you less than the marketing suggests. If your annual giving sits near or below the floor, bunching is where nearly all the benefit lives.
Two other 2026 details belong in the same calculation. The value of itemized deductions is now capped at 35 cents per dollar for taxpayers in the top bracket, so the deduction is worth somewhat less than the old 37 percent assumption. And there is a new charitable deduction available to non-itemizers, but contributions to donor-advised funds are specifically excluded from it, so if you do not itemize, a DAF is not the vehicle that unlocks that break.
2. Am I Comfortable That This Is Irrevocable?
This is the question people ask last and should ask first. A contribution to a donor-advised fund is a completed gift to a public charity. It is gone. You retain the ability to recommend grants and to recommend how the balance is invested, and that is all you retain.
You cannot take it back if your business has a bad year. You cannot redirect it to a family member. You cannot pledge it as collateral. The sponsoring organization has legal control and is not obligated to follow your recommendation, though in practice reputable sponsors follow reasonable ones.
For most donors this is fine, because the money was earmarked for charity anyway. It stops being fine if you fund the account with money you might genuinely need, or if you fund it at a level that assumes next year looks like this year. Size the contribution against the giving you are confident you want to do, not against the maximum deduction you could theoretically claim.
3. Should I Contribute Cash or Appreciated Stock?
For most donors with a taxable brokerage account, long-term appreciated securities are the more efficient contribution. You generally deduct the fair market value and you do not recognize the capital gain you would have owed on a sale, which is a second benefit that cash does not provide.
The trade-off is the deduction limit. Cash gifts to public charities, including DAF sponsors, are generally deductible up to 60 percent of AGI. Long-term appreciated property is generally limited to 30 percent of AGI. Excess above either limit carries forward for up to five years, so hitting the ceiling delays the benefit rather than destroying it, but it does delay it.
Two practical cautions. The asset needs to be held long-term to get fair market value treatment, since short-term appreciated property is generally limited to your basis. And contributing something illiquid, private company shares, real estate, a partnership interest, is possible with many sponsors but involves appraisal requirements, timing risk, and sponsor-specific rules. That is a conversation to have before a deal closes, not during.
4. What Does This Sponsor Actually Charge?
Fees at a donor-advised fund come in layers, and the headline administrative fee is only the first one.
Ask for the administrative fee schedule and where the breakpoints sit. Then ask what the underlying investment pools cost, because that expense ratio stacks on top. Then ask whether there is a minimum initial contribution, a minimum account balance, a minimum grant size, and any fee for a grant to an organization that is not already in the sponsor's system.
The reason to press on this is duration. If you contribute once and grant over ten years, you are paying two layers of fees on a declining balance for a decade. That can be entirely reasonable, and it can also quietly consume a meaningful share of what you intended a charity to receive. The only way to know is to see the schedule in writing.
5. What Happens to the Balance If I Am Not Around?
Every sponsor handles succession, and they handle it differently. You can typically name successor advisors, name charitable beneficiaries to receive the balance outright, or set a schedule that distributes the account over time.
Decide this at opening rather than adding it to the list of things to handle later. An account with no succession instruction generally reverts to the sponsor's own grantmaking, which may be a fine outcome or may be nothing like what you intended.
If you plan to name your children as successor advisors, ask how many generations the sponsor permits and whether there are any conditions. This is also worth coordinating with your estate documents, since a DAF balance is not part of your estate and is not governed by your will.
6. Who Is Modeling This With Me?
The 0.5 percent floor, the 35 percent deduction cap, the 60 and 30 percent AGI limits, the carryforward, and the interaction with a business sale or a large equity event do not resolve into a rule of thumb. They resolve into arithmetic on your specific return.
Two different professionals typically touch this. A CPA runs the deduction mechanics against your actual AGI and any carryforwards. A financial advisor looks at which assets to give, how the contribution fits a multi-year plan, and how it interacts with a liquidity event or a concentrated position.
Capital Area Planning Group is a Washington, DC advisory practice founded in 2024, led by Malcolm Ethridge. Its published client types are high-net-worth and ultra-high-net-worth individuals, business executives, and retirees, which describes most of the population for whom this planning is relevant. Charitable timing questions tend to sit inside larger ones about equity compensation, concentrated stock, and what a windfall year should look like on a tax return.
Fair warning on all of it: charitable planning is a tax and legal question as much as an investment one, and nothing here is a recommendation for your situation. Rules in this area changed in 2026 and can change again. Model it against your own facts with your own advisers before you move money you cannot get back.

Frequently Asked Questions
What is the 0.5 percent AGI floor on charitable deductions? Beginning in 2026, itemizers get no charitable deduction for the first 0.5 percent of adjusted gross income they give. Only giving above that threshold is deductible. On 400,000 dollars of AGI the floor is 2,000 dollars, so a 6,000 dollar year of giving produces a 4,000 dollar deduction. The floor applies to itemizers.
How does a donor-advised fund help with the new floor? By concentrating several years of planned giving into one contribution, the total in that year clears the floor with more of it remaining deductible, and you recommend grants to charities over the following years. The cost is flexibility: the contribution is irrevocable and the money can only go to charity from that point forward.
Is it better to donate cash or appreciated stock to a DAF? Long-term appreciated securities are often more efficient, because you generally deduct fair market value and avoid recognizing the capital gain. The trade-off is a lower deduction ceiling, generally 30 percent of AGI for appreciated property versus 60 percent for cash, with a five-year carryforward for the excess. Short-term holdings are generally limited to basis.
Can I get money back out of a donor-advised fund? No. A contribution is an irrevocable, completed gift to a public charity. You can recommend grants and investment allocations, but the sponsoring organization holds legal control and the funds can only go to charitable purposes. Size the contribution to money you are confident you want to give away.
