If you give to charity every year, there’s a way to get a bigger tax deduction without giving more money. It’s called a donor-advised fund (DAF), and it’s one of the most underused tools in personal tax planning.
What a donor-advised fund is
A DAF is a charitable giving account you open at a sponsor (Fidelity, Schwab, Vanguard all offer them). You contribute cash, stocks, or other assets; you get an immediate tax deduction for the full amount; the money is invested and grows tax-free; and you recommend grants to charities whenever you like, this year, next year, or a decade from now. Legally, the sponsor owns the funds, but in practice you direct them.
The upfront deduction (and why it matters)
The key: you deduct in the year you contribute to the DAF, not the year the charity receives the money. Contribute $20,000 of appreciated stock in December, deduct $20,000 this year, and grant it out over five years. You also avoid capital-gains tax on the appreciated stock, a double benefit cash donations can’t match.
The appreciated-stock superpower, with numbers
Here’s the math that makes DAFs special. Say you own $20,000 of stock with a $8,000 cost basis. If you sell it, you owe capital-gains tax on the $12,000 gain: about $1,800 at the 15% rate, or $2,856 at 23.8% including the net investment income tax. If you donate the shares to a DAF instead, you deduct the full $20,000 fair market value and pay zero capital-gains tax. That’s a double win worth thousands, and it’s the single best reason to fund a DAF with appreciated securities rather than cash.
Contribution limits: the 60% and 30% rules
Cash donations to a DAF are deductible up to 60% of your adjusted gross income (AGI) in a given year. Donations of appreciated securities are deductible up to 30% of AGI. If your contribution exceeds the limit, the excess carries forward for up to five years. For most givers these caps won’t bind, but if you’re donating a large windfall (an IPO, a business sale, a big bonus year), plan the timing so you can actually use the deduction.
Bunching: the real power move
Here’s where DAFs shine. The standard deduction means small annual donations often yield zero tax benefit. Instead, “bunch” several years of giving into one DAF contribution, say $30,000 in one year, to clear the itemizing threshold, then take the standard deduction in the off years. Same total giving, much bigger deduction.
DAF fees and minimums
DAF sponsors charge an administrative fee, typically around 0.6% per year on the balance, plus the expense ratios of whatever the money is invested in. Minimums to open range from $0 at Fidelity Charitable to $5,000 at some other sponsors, and minimum grants are usually $50. For a buy-and-hold giver contributing once every few years, the fees are trivial next to the tax savings. Just don’t let a small balance sit for a decade earning nothing while fees nibble it; invest the DAF balance or grant it out.
Common DAF mistakes
First, forgetting that contributions are irrevocable. Once money goes into a DAF, it can only go to charity, never back to you. Don’t contribute money you might need. Second, contributing cash when you hold appreciated stock. Cash is the worst funding source; appreciated securities are the best. Third, parking the DAF in cash indefinitely. The money can be invested and grow tax-free while you decide which charities to support, so put it to work in a simple index fund allocation instead of letting it idle.
Who it’s for (and who should skip it)
DAFs suit itemizers with lumpy income, anyone donating appreciated stock, and people who want to separate the timing of the deduction from the timing of the giving. If you take the standard deduction every year and give modest cash amounts, a DAF adds complexity without benefit, so just give directly.
