The IRS rules for a donor advised fund govern three things: what you can deduct when you contribute, how the money must be handled while it sits in the fund, and where grants can ultimately go. Break any of them and you can lose the deduction or trigger excise taxes that dwarf the tax benefit you started with. The rules are written in Sections 170, 4943, 4958, 4966, and 4967 of the tax code, and they treat donor advised funds differently from both ordinary public charities and private foundations.
What the Tax Code Treats as a Donor Advised Fund
A donor advised fund is a fund or account that meets three criteria: it is separately identified by reference to contributions of a specific donor, it is owned and controlled by a sponsoring organization, and the donor retains advisory privileges over how the money is distributed or invested.1Justia Law. 26 USC 4966 – Taxes on Taxable Distributions The sponsoring organization must be a public charity, which is why most DAFs sit at community foundations or at the charitable arms of firms like Fidelity, Schwab, and Vanguard.
Legal title belongs to the sponsoring organization. Your grant recommendations are non-binding, and the organization has final say. That structure is what allows the immediate deduction: you have made an irrevocable gift to a public charity, even though you still influence where the money eventually goes.
Deduction Limits for Contributions
Cash contributions to a DAF are deductible up to 60% of your adjusted gross income for the year.2Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts The deduction lands in the year you fund the account, not the year grants leave it. That timing gap is the strategic point of the vehicle: you can bunch several years of giving into one high-income year and recommend grants later.
Anything above the 60% ceiling carries forward for up to five additional tax years and is used in chronological order until exhausted.2Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts The excess is not lost.
Appreciated long-term capital gain property gets treated differently. You deduct the full fair market value on the contribution date, and no capital gains tax is owed on the built-in appreciation, either by you or by the fund.2Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts The AGI ceiling for these gifts is 30%, not 60%, with the same five-year carryforward for the excess. You can elect to use cost basis instead of fair market value to restore the 60% ceiling, but the election applies to all capital gain property donated that year. For most donors with substantially appreciated stock, taking the 30% limit and the full fair market value produces the larger deduction.
Non-publicly traded assets like closely held business interests or real estate can be contributed, but you need a qualified appraisal performed by a qualified appraiser no earlier than 60 days before the contribution, and you must have the appraisal before the filing deadline (including extensions) for the return that first claims the deduction.3Internal Revenue Service. Instructions for Form 8283 Many sponsoring organizations screen these gifts carefully because of the complexity.
Substantiation You Need to Keep the Deduction
Every contribution of $250 or more requires a contemporaneous written acknowledgment from the sponsoring organization stating its name, the cash amount or a description of the property, and whether any goods or services were provided in exchange.4Internal Revenue Service. Charitable Contributions Written Acknowledgments “Contemporaneous” means you have it by the earlier of your filing date or the due date including extensions. Without it, the IRS can disallow the whole deduction, no matter how well documented the gift is otherwise.
Noncash contributions totaling more than $500 require Form 8283 attached to your return.5Internal Revenue Service. About Form 8283 – Noncash Charitable Contributions Any single item or group of similar items valued over $5,000 requires Section B of Form 8283, which needs a qualified appraisal and the appraiser’s signature in Part IV.3Internal Revenue Service. Instructions for Form 8283 Filing Section A when Section B applies, or skipping the appraisal, is a common way to lose the deduction on audit.
How the Money Grows and Gets Distributed
Investment growth inside the fund is not taxed. The sponsoring organization is a public charity, so gains, interest, and dividends earned by the account are exempt from income and capital gains tax.
Unlike private foundations, which must distribute at least 5% of net investment assets annually, DAFs have no minimum payout requirement under current law. Legislation like the Accelerating Charitable Efforts (ACE) Act has been introduced to change this, but no mandatory distribution timeline exists yet. Sponsoring organizations often set their own activity policies, and dormant accounts may be subject to the organization’s variance power to redirect the funds.
Where Grants Can Legally Go
Most grants go to organizations recognized under Section 501(c)(3) with a current IRS determination letter. These distributions are routine and require no special procedure.
Grants to individuals are prohibited. A distribution from a DAF to any natural person is automatically a taxable distribution and triggers excise taxes on the sponsoring organization and potentially on the fund manager.1Justia Law. 26 USC 4966 – Taxes on Taxable Distributions Narrow exceptions exist for pre-approved programs administered by the sponsoring organization itself, such as scholarships or disaster relief where the sponsoring organization selects recipients through an independent process.
Grants to organizations that are not public charities, including private non-operating foundations, require the sponsoring organization to exercise expenditure responsibility: a written agreement with the recipient about the use of funds, monitoring of spending, and reporting to the IRS.6Internal Revenue Service. Grants by Private Foundations – Expenditure Responsibility If that responsibility isn’t carried out, the grant becomes a taxable distribution.
Most foreign organizations fall into the same category. The sponsoring organization must either perform full expenditure responsibility or obtain an equivalency determination confirming the foreign entity would qualify as a U.S. public charity.6Internal Revenue Service. Grants by Private Foundations – Expenditure Responsibility The vetting burden sits with the sponsoring organization, not the donor.
Pledges
Whether a DAF grant can satisfy a donor’s charitable pledge is more nuanced than many advisors realize. IRS Notice 2017-73 proposed a framework: a DAF distribution to a charity where the donor has an outstanding pledge is not treated as a prohibited benefit if the sponsoring organization makes no reference to the pledge when making the distribution, the donor receives no other more-than-incidental benefit, and the donor does not claim a separate charitable deduction for the distribution.7Internal Revenue Service. Notice 2017-73 – Donor Advised Funds That guidance is still in proposed form, but taxpayers may rely on it until final regulations issue. Safer practice: keep any mention of a pledge out of the grant documentation, and never use a DAF grant to discharge a legally enforceable financial obligation such as a contract or a court-ordered payment.
Benefits to You or Family Members
The strictest rules protect against personal benefit flowing back from the fund. Two provisions overlap.
Under Section 4967, if a donor, advisor, or related person recommends a distribution that results in any of them receiving a more-than-incidental benefit, the tax is 125% of the benefit, paid by the person who gave the advice or received it.8Justia Law. 26 USC 4967 – Taxes on Prohibited Benefits A fund manager who knowingly agrees owes 10% of the benefit amount. Advise a $50,000 grant to a charity, receive a $10,000 personal benefit in return, and the tax on you alone is $12,500. Event tickets, membership privileges, and any tangible return can count.
Section 4958 adds a second layer that does not apply to ordinary public charities. Any grant, loan, compensation, or similar payment from a DAF to a donor, advisor, or a person related to either is automatically an excess benefit transaction, and the entire payment is treated as the excess benefit.9Legal Information Institute. 26 USC 4958 – Excess Benefit Transaction Definition Whether the payment was reasonable or at fair market value is irrelevant. If money flows from the DAF to a disqualified person, it is an excess benefit. Never use DAF funds to buy anything from, pay compensation to, or otherwise benefit the donor, the donor’s family, or any entity the donor controls.
Contributing Closely Held Business Interests
DAFs are treated as private foundations under the excess business holdings rules.10Internal Revenue Service. IRC Section 4943 – Taxes on Excess Business Holdings The DAF and all disqualified persons combined generally cannot hold more than 20% of the voting stock of any business enterprise. That rises to 35% when unrelated parties keep effective control of the company. A de minimis exception applies when the DAF and related private foundations together hold no more than 2% of both voting stock and total share value.
Violating the limit brings an initial excise tax of 10% of the value of the excess holdings. If the holdings are not reduced within the correction period, an additional 200% tax applies.10Internal Revenue Service. IRC Section 4943 – Taxes on Excess Business Holdings Contributing a large block of closely held stock without running these numbers first can produce a tax bill larger than the deduction it generated.
The Excise Taxes at a Glance
- Taxable distribution (Section 4966): 20% of the distribution on the sponsoring organization; 5% on a fund manager who knowingly agreed, capped at $10,000 per distribution. Multiple managers are jointly and severally liable, but the cap is per distribution, not per manager.1Justia Law. 26 USC 4966 – Taxes on Taxable Distributions
- Prohibited benefit (Section 4967): 125% of the benefit on the person who advised or received; 10% on a knowing fund manager.8Justia Law. 26 USC 4967 – Taxes on Prohibited Benefits
- Automatic excess benefit (Section 4958): the entire payment is the excess benefit when funds go to a donor, advisor, or related person.9Legal Information Institute. 26 USC 4958 – Excess Benefit Transaction Definition
- Excess business holdings (Section 4943): 10% initial, 200% if uncorrected.10Internal Revenue Service. IRC Section 4943 – Taxes on Excess Business Holdings
The DAF rules under Section 4966 don’t have the escalating correction-period structure that applies to private foundation taxable expenditures under Section 4945.11Internal Revenue Service. Taxes on Taxable Expenditures – Private Foundations The 20% and 5% amounts are the tax. Confusing the two regimes is one of the more common advisor mistakes.
