A provision in Trump’s tax bill could make donor-advised funds an even more popular form of giving. Donor-advised funds, or DAFs, are accounts where donors can contribute funds, immediately get a tax deduction, and “advise” on where to donate — and they are becoming increasingly popular. As Daniel Heist, a professor at Brigham Young University and a lead researcher on the 2025 National Survey of DAF Donors, put it, “they’re growing like crazy.” Donors can contribute non-cash assets, like appreciated securities or crypto, to DAFs, and the funds grow over time. Technically, donors don’t control the funds in their DAF, but practically speaking, they can direct the money to any accredited charity. “As long as you’re following the rules of the DAF provider, you should always have those recommendations honored,” Mitch Stein, the head of strategy at Chariot, a technology company focused on DAFs, said. Private foundations have to distribute at least 5% of their assets annually for charitable purposes, but DAFs don’t have payout requirements. Donors also don’t report their gifts to individual organizations on their taxes, and instead report that they gave to the DAF.
