Donor-Advised Funds: Bunching Strategy and Tax Benefits

$234 Billion Sitting in Charitable Accounts — Largely Untouched

Donor-advised funds collectively held $234 billion in assets at the end of 2022, according to the National Philanthropic Trust, with over $52 billion granted to charities that year. The gap between assets held and assets granted has become a source of criticism — some DAF accounts sit for years with no grants made — but for strategic givers, the accumulation of assets is precisely the point. A donor-advised fund is a tax-advantaged charitable vehicle that allows you to take the full charitable deduction in the year of contribution, then grant the money to actual nonprofits on any timeline you choose, while the assets grow tax-free in the interim.

The mechanics are straightforward. You contribute cash, securities, or other assets to a DAF sponsored by a public charity (Fidelity Charitable, Schwab Charitable, Vanguard Charitable, community foundations, and others). You receive the full charitable deduction immediately. The sponsoring organization takes legal ownership of the assets. You retain advisory privileges — the right to recommend grants to IRS-qualified 501(c)(3) organizations — but not legal control. The sponsor retains the right to reject grant recommendations, though in practice this is rare except for impermissible grants (grants to individuals, grants providing personal benefit, etc.).

The Bunching Strategy: Turning Small Deductions Into Large Ones

The 2017 Tax Cuts and Jobs Act doubled the standard deduction — $29,200 for married filing jointly in 2024 — making itemized deductions irrelevant for approximately 90% of taxpayers in any given year. The bunching strategy uses a DAF to regain the tax benefit of charitable giving by concentrating multiple years' worth of planned donations into a single calendar year.

Assuming $10,000 in other itemized deductions (mortgage interest, state taxes), bunching three years of $15,000 charitable contributions into a single year produces $10,000 + $45,000 = $55,000 in Year 1 itemized deductions versus the $29,200 standard — a $25,800 incremental deduction. At a 24% marginal rate, that is $6,192 in additional tax savings over the three-year cycle, simply from timing.

• Contributors can bunch 5, 10, or even 20+ years of anticipated giving into a single contribution year
• The DAF then makes grants to chosen nonprofits over the intended time horizon
• Appreciated securities contributions avoid capital gains on the appreciated portion
• The donor can continue regular annual giving to charities from the DAF with no additional tax benefit, but the deduction has already been captured

Tax-Free Growth: The Compounding Advantage

Assets in a DAF are invested and grow completely free of capital gains, dividends, and income tax. A $100,000 contribution invested in a diversified equity portfolio for 10 years at 7% annual return becomes approximately $196,715 available for charitable grants — a $96,715 growth that was never taxed. The donor did not pay capital gains on the appreciation; the charity receives the full accumulated value.

This is particularly powerful for donors who contribute highly appreciated non-cash assets. Donating $100,000 worth of stock with a $20,000 cost basis directly to a DAF allows the DAF to sell the stock without recognizing the $80,000 gain. The donor deducts the full $100,000 fair market value. If the donor had sold the stock personally and donated cash, they would have paid $15,960 in capital gains taxes (20% federal + 3.8% NIIT on $80,000 gain) before even making the charitable contribution.

Comparing the Major Sponsors

Fidelity Charitable is the largest DAF sponsor in the United States by assets under management, processing over $11 billion in grants in 2022. Vanguard Charitable's higher minimums make it better suited for larger donors who prefer index-fund investing. Community foundations offer local grant-making expertise and legacy naming opportunities that national sponsors do not provide.

Grant Timing and Recommendations

• Grants can be made at any time after the contribution is received and invested — there is no legal minimum distribution rate for DAFs
• The sponsoring organization must approve each grant; it must go to a qualifying 501(c)(3) public charity, not a private foundation or non-U.S. charity (without special procedures)
• Anonymous grants are permitted — DAFs are one of the few vehicles that allow tax-deductible anonymous philanthropy
• DAF accounts can be passed to successor advisors (children, grandchildren) upon the original donor's death, creating a multi-generational charitable vehicle
• Grants to nonprofits can be designated for general operating support or restricted to specific programs
