The donor-advised fund
Rees Calder · 28 April 2026 · 7 min read
A donor-advised fund is a charitable savings account. You put money in, get the tax deduction immediately, and then recommend grants to charities over time. The money is legally irrevocable (it belongs to the fund, not you), but you advise where it goes. The fund almost always follows your advice. In practice, it works like a charitable bank account with a tax benefit up front.
DAFs held $234 billion in the US at the end of 2023 (National Philanthropic Trust, 2024). They've grown roughly 400% in the past decade. In the UK, the Charities Aid Foundation's Charity Account is the closest equivalent, though the market is much smaller. DAFs are now the fastest-growing vehicle in philanthropy, and they're genuinely useful for certain donors. They're also controversial for reasons worth understanding.
How they work
Step 1: Contribute. You transfer cash, shares, or other assets to the DAF. You receive a tax deduction in the year of contribution (income tax in the US, Gift Aid-equivalent in the UK via CAF). The money is now legally charitable. You can't take it back.
Step 2: Invest. The DAF provider invests your balance, typically in a range of funds similar to retirement accounts. Common providers: Fidelity Charitable (the largest, $56 billion in assets), Schwab Charitable, Vanguard Charitable in the US. CAF and the National Philanthropic Trust in the UK. The investment returns are tax-free, so the balance grows faster than in a taxable account.
Step 3: Grant. You recommend grants to any registered charity, at any time. Most providers process recommendations within 1-5 business days. There's no legal deadline for when you must grant the money (this is the controversial part). You can grant immediately, next year, or decades later.
When DAFs make sense
Three scenarios where a DAF genuinely adds value over direct giving.
Lumpy income, smooth giving. If your income varies significantly year to year (freelancers, entrepreneurs, anyone with stock-based compensation), a DAF lets you batch charitable contributions in high-income years for maximum tax benefit, then grant to charities steadily over time. You contribute £20,000 in a boom year, get the full deduction, then grant £2,000 per year for the next decade. Your giving stays consistent even when your income doesn't.
Appreciated assets. If you hold shares that have appreciated significantly, donating them to a DAF avoids capital gains tax entirely while generating a deduction for the full market value. On a £10,000 gain, this can be worth £2,000-3,000 in tax savings compared to selling the shares and donating cash. For founders and early employees with concentrated stock positions, this is often the most tax-efficient way to give.
Giving pause. If you want to commit money to charity irrevocably but haven't decided where to direct it, a DAF holds the funds in a charitable vehicle while you research. This is particularly useful for people making large one-time gifts (an inheritance, a windfall, a sale of business) who want the tax benefit now but need time to decide on allocation.
The controversy
DAFs have attracted serious criticism from philanthropy watchdogs, congressional scrutiny, and some effective giving advocates. The core issue: money goes in, gets a tax deduction, but doesn't necessarily come out to working charities any time soon.
The payout problem. There is no legal minimum payout requirement for DAFs (unlike private foundations, which must distribute 5% of assets annually). The Institute for Policy Studies (2024) found that the average DAF payout rate is roughly 20-25% per year, which sounds healthy, but the aggregate balance keeps growing because inflows exceed outflows. In 2023, $105 billion went into US DAFs and $52 billion came out. The pile gets bigger every year.
Critics argue this is a publicly subsidised savings account masquerading as philanthropy. You get the tax deduction when money enters the DAF, but the charity doesn't benefit until it leaves. If a donor contributes to a DAF and never grants the money, the public treasury lost the tax revenue and the charitable sector gained nothing.
The warehousing concern. Some donors use DAFs primarily as tax-efficient investment vehicles, contributing appreciated stock for the deduction and then making minimal grants. The Philanthropy Roundtable argues this is a small minority. The Institute for Policy Studies argues it's more common than reported. The data is murky because most DAF providers don't publish account-level grant rates.
The transparency gap. When a DAF makes a grant to a charity, it appears in the charity's accounts as a gift from the DAF provider (e.g., "Fidelity Charitable"), not from the individual donor. This reduces transparency about who is funding what. For charities, it also makes donor relationship management harder.
The effective giving perspective
Within the effective giving community, DAFs are viewed pragmatically.
GiveWell's position: Neutral on DAFs as a vehicle. They recommend direct giving for simplicity but acknowledge DAFs make sense for donors with appreciated assets or variable income. They explicitly note that the tax savings from a DAF contribution can be redirected to additional charitable giving, potentially increasing total impact.
Giving What We Can's position: They count DAF contributions toward the 10% pledge if the donor has a clear plan to grant the funds within a reasonable timeframe. They don't count indefinite warehousing.
The timing argument. Some EA-aligned donors argue for delayed granting: invest the DAF balance in equities, let it compound, and grant more later. The counterargument (from GiveWell and others): the best giving opportunities available now may not exist later, and people in extreme poverty need help now, not in 20 years. The returns to early intervention (childhood health, nutrition, education) are time-sensitive.
UK-specific considerations
The UK DAF market is smaller and structured differently.
CAF Charity Account. The most common UK vehicle. Contributions receive Gift Aid (adding 25% for basic-rate taxpayers). Higher-rate taxpayers can claim additional relief via self-assessment. The account can hold and invest funds, and grants are processed to any UK registered charity.
CAF's payout rate. CAF reports that roughly 85% of contributions are granted within 2 years, significantly higher than US DAF averages. The UK market doesn't (yet) have the warehousing problem to the same degree.
Payroll giving vs. DAF. For regular giving from employment income, payroll giving is more tax-efficient than a DAF because it operates from gross salary. DAFs are better for irregular or asset-based giving.
Should you use one?
Yes if: You have variable income, significant appreciated assets, or want to make a large one-time commitment with time to research allocation. The tax advantages are real and meaningful.
No if: You're making regular monthly donations from salary. Direct giving or payroll giving is simpler, equally tax-efficient, and avoids the risk of "out of sight, out of mind" accumulation.
The commitment rule: If you open a DAF, set a personal payout target. Grant at least 10-20% of the balance annually, or set calendar reminders to make grant recommendations quarterly. The biggest risk of a DAF isn't the fees (typically 0.15-0.60% annually). It's the psychological distance between contributing and granting.
One sentence
A donor-advised fund is a powerful tax tool for lumpy income and appreciated assets, but only if you actually grant the money. Set a payout target, review quarterly, and treat it as a pipeline to charity, not a parking lot.
