Donor-advised funds reached a record 3.56 million accounts and $326 billion in total assets in fiscal year 2025, according to the Donor Advised Fund Research Collaborative's Annual DAF Report, even as new federal tax rules effective January 1, 2026 are forcing donors and their advisors to fundamentally rethink how, when, and why they give.
Why It Matters
DAFs have become the fastest-growing charitable giving vehicle in the United States, with assets growing 27.5% in a single year and contributions rebounding 37.3% to reach $89.6 billion. At the same time, the One Big Beautiful Bill Act — signed into law in July 2025 — introduced new constraints on charitable deductions that take effect this year, creating both urgency and complexity for high-net-worth donors, financial advisors, and the nonprofits that depend on them.
Context
For years, DAFs have attracted donors with a simple value proposition: contribute assets now, claim the tax deduction immediately, and distribute funds to charities over time. That model helped DAFs grow from a niche tool to a mainstream philanthropic instrument, with DAFgiving360 alone distributing nearly $8.9 billion in grants in fiscal year 2025 — a 34% year-over-year increase.
The donor base has also broadened. While platforms like Vanguard Charitable maintain $25,000 minimums that attract high-net-worth individuals, lower entry points at DAFgiving360 and Fidelity Charitable have made the vehicle accessible to a wider range of givers. According to Schwab's 2025 RIA Benchmarking Study, 86% of financial advisor firms now offer charitable planning services, and 78% of DAF assets are associated with an advisor relationship.
Analysis
The OBBBA introduces three significant changes to the charitable deduction landscape for 2026. Itemizing donors must now clear a 0.5% adjusted gross income floor before any charitable gift becomes deductible — meaning a donor with $200,000 in AGI cannot deduct the first $1,000 of their giving. Top-bracket taxpayers face an additional constraint: the value of all itemized deductions is now capped, reducing the effective benefit of charitable gifts by roughly 5.4% for those in the 37% bracket. Meanwhile, non-itemizers gained a modest new benefit — a universal above-the-line deduction of $1,000 for individuals and $2,000 for joint filers — but it applies only to direct cash gifts. Contributions to DAFs do not qualify.
For high-net-worth donors, the combined effect is meaningful. An individual with $10 million in AGI making a $1 million charitable gift in 2026 would see their allowable itemized deduction reduced by more than 10% compared with the same gift made in 2025, according to private banking analysts who modeled the scenario. The math makes the case for action.
For donors who fund DAFs, the strategic response is bunching — front-loading multiple years of charitable contributions into a single year to clear the AGI floor and maximize deduction value. A donor contributing to a DAF can claim the deduction in the year of contribution and distribute grants to charities over time, preserving flexibility while locking in more favorable tax treatment. Financial advisors across the wealth management industry have identified this approach as the primary planning tool available to donors navigating the new rules.
Nonprofits are watching these changes carefully. With the universal deduction excluding DAF contributions, there is concern that some donors will redirect giving toward direct gifts to capture that new benefit — potentially disrupting the planned, sustained giving patterns that DAF distributions have historically enabled. Major wealth advisors have noted rising anxiety among nonprofits about the funding implications, particularly for organizations that rely heavily on DAF distributions as a predictable revenue stream.
Supporting Details
The scale of DAF activity underscores what is at stake. In fiscal year 2025, DAFgiving360 donors distributed more than $148 million to disaster relief efforts, responding to wildfires, floods, and international humanitarian crises. Nearly 40% of all DAF distributions were structured as recurring or scheduled grants, reflecting the growing shift toward intentional, long-term philanthropic planning. Investment growth within DAF accounts created an additional $4 billion available for charitable distribution in the same period.
For nonprofits on the receiving end, DAFs represent both opportunity and operational challenge. Gifts can take two to six weeks to process and distribute, requiring organizations to plan well ahead of year-end. Donors also retain the option to give anonymously, complicating stewardship. Fundraising practitioners recommend that nonprofits proactively list DAF acceptance on their websites, include their EIN to facilitate easy donor searches, and encourage donors to set up recurring grants through their DAF portals — a feature now available on most major platforms. Some organizations are also encouraging donors to name them as DAF beneficiaries, a succession planning option that many account holders remain unaware of.
The debate over payout rates — long a flashpoint for DAF critics — continues to evolve. The DAF Research Collaborative reports median payout rates near 9–10%, well above the 5% minimum required of private foundations, though the absence of a mandated DAF floor keeps pressure on policymakers and sponsoring organizations to demonstrate that assets are moving, not accumulating.
