Donor-advised funds: bunching your giving into a real deduction
The short answer
Since the standard deduction roughly doubled in 2018, most people who give a modest amount to charity every year get zero incremental tax benefit for it — they're already below the itemizing threshold. A donor-advised fund (DAF) fixes this by letting you "bunch" several years of planned giving into a single high-income year, clear the itemizing threshold, take the full deduction that year, and then grant the money out to charities over the following years on your own schedule. Fund it with appreciated stock instead of cash and you also skip capital gains tax on the appreciation.
Who this works for — and who it doesn't
Good fit
- Consistent charitable givers whose annual giving alone doesn't clear the standard deduction
- High-income years — a bonus, a sale, an S-corp distribution spike — where extra deductions are worth the most
- Owners holding appreciated stock or other securities they were planning to eventually sell or give anyway
Not a fit
- Donors who already itemize comfortably every year with no bunching benefit to capture
- Anyone who might want the contributed funds back — a DAF contribution is irrevocable
- Gifts that need to go to a specific non-charitable recipient or serve a non-501(c)(3) purpose
How it works
- Open a DAF through a sponsoring charity (many major brokerages run one) — setup is typically free or low-cost.
- Contribute cash or appreciated securities in a high-income year; you get the deduction that year, at fair market value for securities held over a year.
- The money is invested inside the fund and can grow tax-free while awaiting distribution.
- You recommend grants to qualified 501(c)(3) charities on whatever timeline you want — next month or over the next ten years.
- You itemize in the funding year and can take the standard deduction in the lighter years that follow, since the giving is already "banked."
A worked example
The Reyes family typically gives $12,000 a year to charity but their other itemized deductions plus $12,000 fall short of the standard deduction most years. In a year with a large bonus, they bunch three years of giving at once.
Bunching three years into one
Illustrative only; the exact incremental benefit depends on your other itemized deductions and the standard deduction in effect that year.
Common mistakes
- Contributing cash instead of appreciated stock when appreciated stock was available and would have avoided capital gains tax too
- Bunching in a year that wasn't actually your highest-income year
- Forgetting AGI-based percentage limits on the deduction in the contribution year for very large gifts
- Treating the DAF as a rainy-day fund you might reclaim — contributions are irrevocable once made
Frequently asked questions
Is a donor-advised fund the same as a private foundation?
No, and that's most of the appeal. A DAF is sponsored by a public charity, has minimal setup and administration cost, and no mandatory annual distribution requirement, unlike a private foundation, which requires its own filings and a 5% annual payout.
Can I get a deduction now and decide the charities later?
Yes — that is the entire mechanism. You get the deduction in the year you fund the DAF, then recommend grants to specific charities whenever you want, with no deadline to distribute the full balance.
Should I donate cash or appreciated stock?
Appreciated stock held over a year is usually better — you generally deduct the full fair market value and avoid ever paying capital gains tax on the appreciation, which cash contributions can't replicate.
