Use Donor Advised Funds (DAF)

A Donor Advised Fund (DAF) is an account at a sponsoring public charity that you fund now, deduct now, and grant out later. It solves three problems at once: it decouples the deduction year from the giving year, which is what makes bunching against the 0.5% floor work; it accepts appreciated and illiquid assets that a small charity has no ability to process; and it lets the assets keep compounding untaxed between funding and granting.

1.
Open an account at a sponsor — Fidelity Charitable, DAFgiving360 (formerly Schwab Charitable), Vanguard Charitable, or a community foundation.
2.
Contribute appreciated long-term securities. Take the deduction this year, at fair market value, subject to the 30% AGI ceiling for property (section “Limits on Contributions”).
3.
Invest the balance from the sponsor’s menu.
4.
Recommend grants to operating charities over the following years, named or anonymous.
5.
An employer match, if you have one, generally applies at the grant step, not the funding step — check your program’s rules, because some match only direct gifts.

Fund it in a high-bracket year: a liquidity event, an option exercise, a business sale. That is the year the deduction is worth the most, and the grants can trickle out over the following decade at whatever pace you like.

Costs and minimums. Sponsors charge an administrative fee on assets — roughly 0.6% at the large national sponsors, declining at higher balances — plus the expense ratios of the underlying funds. Minimums have collapsed: Fidelity Charitable and DAFgiving360 now open an account with no minimum at all, while Vanguard Charitable still requires $25,000. Weigh the ongoing fee against the benefit; for a donor who will grant the whole balance out within a year or two, the fee is trivial, and for one who intends to hold for decades it is a real drag that argues for a low-cost sponsor.

What you give up, and the rules people break. The trade is control, and the constraints are stricter than the marketing suggests:

The contribution is irrevocable.

The money is gone the moment you fund. You cannot get it back if your circumstances change, and you should not fund a DAF with money you might need.

Your grants are only advisory.

Legally the sponsor may decline. In practice they almost never do for a normal grant to a qualified charity, but the recommendation is not a direction, and this is what makes the up-front deduction defensible.

You may receive no benefit from a grant.

Under IRC §4967, “Taxes on prohibited benefits” a donor who receives more than an incidental benefit from a DAF grant owes an excise tax of 125% of that benefit. So: no gala tickets, no auction bids, no charity dinner where part of the ticket is a meal, and no using a grant to satisfy a pledge you made personally. Pay for the gala from your checkbook and grant the rest from the DAF.

DAFs cannot grant to individuals

— no scholarships to a named student, no hardship grants — nor generally to private non-operating foundations. A grant outside the permitted class is a taxable distribution under IRC §4966, “Taxes on taxable distributions”, taxed at 20% to the sponsor and 5% to any fund manager who knowingly agreed to it.

A QCD cannot be directed to a DAF.

If you are over 70½ and giving from an IRA, the DAF is specifically excluded (section “Give From the IRA After 70½: the QCD”).

The new non-itemizer deduction excludes DAFs too.

If you take the standard deduction and want the $1,000/$2,000 non-itemizer gift under IRC §170(p) — taken from AGI, not above the line — it must go directly to a public charity.

One timing caution the marketing omits: appreciation inside the DAF is never deductible. You deduct the value on the day you fund it. If you contribute $100,000 and grant it out a decade later having grown to $250,000, the charity gets $250,000 — genuinely good — but your deduction was always $100,000. Fund early enough to bunch giving effectively, without donating prematurely and forfeiting deductions on future asset appreciation.
