Donor-Advised Fund: Definition and How It Works

A donor-advised fund (DAF) is a separately identified charitable giving account maintained by a sponsoring organization — a public charity such as a community foundation or the charitable arm of a brokerage firm — to which a donor makes an irrevocable, tax-deductible contribution and retains advisory privileges over how the accumulated assets are ultimately granted to qualifying public charities. Defined in IRC §170(f)(18), a DAF meets three statutory criteria: the account is separately identified by reference to the donor's contributions; legal ownership and control rest with the sponsoring organization; and the donor (or donor-appointed advisor) holds the privilege of providing advice on the distribution or investment of account assets. The sponsoring organization has legal authority to reject an advisory recommendation, though in practice sponsoring organizations follow donor instructions for distributions to qualifying charities.

How a DAF Works

A donor opens a DAF account with a sponsoring organization — Fidelity Charitable, Schwab Charitable, Vanguard Charitable, and community foundations are the most common — and makes a contribution of cash, publicly traded securities, or other qualifying assets. The contribution is irrevocable: once assets enter the DAF, they cannot be returned to the donor. In exchange, the donor receives a charitable deduction in the year of contribution, not in the year grants are distributed to charities.

The DAF account grows tax-free. The sponsoring organization invests the contributed assets according to options the donor selects (typically mutual fund pools). The donor then recommends grants to qualifying IRC §501(c)(3) public charities at any time — immediately, in subsequent years, or spread over decades. There is no legal requirement to distribute any minimum amount annually, though some sponsoring organizations impose inactivity policies.

Contribution deduction limits (IRC §170):

Unused deductions carry forward for five years (IRC §170(d)(1)).

Eligible grant recipients: Grants may only go to U.S. public charities described in IRC §501(c)(3) — and specifically, DAFs cannot make grants to other donor-advised funds, private non-operating foundations, or supporting organizations (IRC §170(f)(18)(B)). Individuals are not eligible grant recipients.

QCDs and DAFs do not mix: Qualified Charitable Distributions from an IRA (IRC §408(d)(8)) cannot be directed to a donor-advised fund. QCDs must go directly from the IRA custodian to a qualifying public charity, and a DAF does not qualify. This is a common compliance error CPAs must watch for in clients who are 70½ or older.

The DAF as a Tax Planning Vehicle

The DAF's primary planning value is timing separation: the donor captures the charitable deduction when contributing assets to the DAF, then distributes grants to specific charities on a separate, more flexible timeline. This separation creates two key planning opportunities:

1. Bunching deductions: Clients who ordinarily claim the standard deduction can consolidate two or three years of charitable giving into a single DAF contribution, itemize in the contribution year (claiming a larger deduction than in any individual year), and take the standard deduction in the off years — all without interrupting the flow of charitable support to their preferred organizations. For a full illustration, see Standard Deduction vs. Itemized Deductions.

2. Donating appreciated securities: Contributing publicly traded stock or mutual fund shares held more than 12 months to a DAF avoids the capital gains tax that would arise on a sale, while generating a deduction at the full fair market value. This is more efficient than selling the shares and donating cash. See Capital Gains Tax Rates for the rate differential at stake.

Post-OBBBA planning: Beginning in 2026, OBBBA imposed a 0.5% AGI floor and a 35% benefit cap on charitable deductions for high-income filers, reducing the marginal tax value of annual gifts. The DAF front-loading strategy — contributing multiple years of charitable intent in a single year before these restrictions take full effect — is now the central vehicle for preserving giving-related deductions. See OBBBA Charitable Giving Strategies for High-Income Clients in 2026 for the mechanics and client-level modeling.

Related Terms

• Qualified Charitable Distribution (QCD) — An alternative charitable giving mechanism for IRA owners age 70½+; bypasses income recognition entirely but cannot use a DAF as recipient
• Private foundation — A separately incorporated charitable entity with more donor control but greater administrative burden, lower AGI limits (30% cash, 20% appreciated property), and excise taxes on undistributed income
• Charitable remainder trust (CRT) — An irrevocable trust that provides an income stream to the donor for a term or lifetime, with the remainder passing to charity; more complex to establish but can produce a partial deduction and income-stream benefits

How CPAs Use This Term in Practice

CPAs encounter DAFs most commonly in three contexts: (1) recommending a bunching strategy for clients hovering near the standard-deduction threshold, (2) advising on the tax-efficient disposition of large appreciated-securities positions when a client has charitable intent, and (3) modeling post-OBBBA charitable deduction value for high-income clients who need to decide whether to pre-fund a DAF before year-end. For estate planning clients, DAFs also function as a low-cost alternative to a private foundation when the client wants a legacy giving vehicle without the administrative overhead and minimum-distribution requirements. See Estate and Gift Tax Planning Under the OBBBA $15M Exemption for how DAF planning integrates with broader transfer-tax strategy.
