You’ve Been Giving Money Away the Expensive Way
If you give to charity every year and you also hold appreciated stock, the check you write is the worst version of that gift. The gap between the two has a specific dollar figure attached, and it is wider than most people guess.
When you write a check, the money in it already survived a tax event. You sold shares, or you earned the cash as salary, and the government already took its cut before the dollars hit the envelope. When you hand a charity the shares themselves instead, that tax event never happens. The capital gain evaporates. The charity gets the full pre-tax value, you get a deduction for that same full value, and nobody owes capital gains tax on the appreciation because nobody ever sold anything. You already sit on a pile of stock from RSU vests, ESPP purchases, or a decade of an S&P 500 index fund that quietly tripled. Giving it away directly, through a donor-advised fund (DAF), is the mechanism built for exactly this. This isn’t a loophole. It’s IRC Section 170 working as designed, and most people who give five figures a year to charity never use it.
The Worked Example: $50,000 of RSU Shares
Say you’re a single-filer engineer with $600,000 of AGI this year, comfortably in the 35% federal bracket and past the 20% long-term capital gains bracket threshold, and you also owe the 3.8% net investment income tax (NIIT applies above $200,000 MAGI for single filers, a threshold that hasn’t moved since 2013). You live in a state that taxes income at 9%, roughly what a high-tax state charges someone at this level.
You hold $50,000 of vested company stock with a $10,000 cost basis. That’s a $40,000 long-term capital gain sitting inside the position.
Path A: sell, then write a check.
- Federal capital gains tax: $40,000 × 23.8% (20% LTCG + 3.8% NIIT) = $9,520
- State tax on the gain: $40,000 × 9% = $3,600
- Total tax on the sale: $13,120
- Cash left to donate: $50,000 − $13,120 = $36,880
You write a $36,880 check. Starting in 2026, the first 0.5% of your AGI in charitable giving isn’t deductible at all, a new floor under the One Big Beautiful Bill Act (OBBBA). At $600,000 AGI, that’s $3,000 off the top. Deductible amount: $33,880. At a combined 44% marginal rate (35% federal + 9% state), that deduction saves you $14,907 in tax.
Path B: donate the shares directly to a DAF.
- No sale, no capital gains tax.
- The DAF receives the full $50,000, comfortably inside the 30% of AGI limit that applies to appreciated stock donated to a public charity or DAF ($180,000 limit on $600,000 AGI).
- Same 0.5% floor applies: $50,000 − $3,000 = $47,000 deductible.
- At 44%, that saves you $20,680 in tax.
| Path A: Sell then donate cash | Path B: Donate shares directly | |
|---|---|---|
| Charity/DAF receives | $36,880 | $50,000 |
| Tax deduction (after 0.5% floor) | $33,880 | $47,000 |
| Tax savings from deduction | $14,907 | $20,680 |
Donating the shares directly puts $13,120 more into the charity’s hands from the exact same starting asset, and that number is not a coincidence. It’s precisely the capital gains tax you’d have otherwise paid. The math doesn’t care that you liked the stock or that HR made it feel like “your” money the moment it vested. Once it’s appreciated, it’s a tax liability wearing a ticker symbol, and donating it is how you take that liability off the board for free.
The New 0.5% Floor Changes the Bunching Math
Before 2026, giving a flat $10,000 a year to charity mostly meant you took the standard deduction anyway and got zero marginal tax benefit from the giving, unless your other itemized deductions (mortgage interest, state taxes) were already close to the line. For 2026 the standard deduction is $16,100 single, $32,200 married filing jointly, $24,150 head of household. Add the new 0.5%-of-AGI floor on top, and small annual gifts get squeezed from both directions: they’re often too small to clear the standard deduction, and now the first slice of whatever you do give doesn’t count at all.
The fix is bunching, and the new floor actually makes it stronger, not weaker.
Say your AGI is $250,000, you have about $9,000 a year in other itemizable expenses, and you give $10,000 a year to charity by check.
Spread out over 5 years: Each year: $9,000 + $10,000 = $19,000 gross itemizable, minus the $1,250 floor (0.5% of $250,000) = $17,750 deductible. That’s barely above the $16,100 standard deduction, so you itemize every year for a thin marginal benefit. Five years of deductions: $17,750 × 5 = $88,750.
Bunched through a DAF: Contribute $50,000 (five years of giving) to a DAF in year one. That year: $9,000 + $50,000 = $59,000 gross, minus the $1,250 floor = $57,750 deductible. In years two through five, you have no charitable gift to make (you already funded the DAF, which grants out to charities on your recommendation over time), so you just take the $16,100 standard deduction each year. Five years of deductions: $57,750 + ($16,100 × 4) = $122,150. The standard deduction is indexed to inflation, so the off-year figures will each be a little higher and the real gap is slightly wider than this.
Same $50,000 given away over the same five years. $33,400 more in total deductions, just by changing the timing. The 0.5% floor only bites once (in the bunch year) instead of nibbling at every single year’s gift, and the standard deduction stops going to waste in the off years. If you’re going to donate appreciated stock anyway, bunching it into one contribution year through a DAF is close to free money.
Pick Your Lots on Purpose
Not all your shares have the same basis. RSUs vest in batches at different prices; ESPP shares accumulate across purchase periods; an index fund position built up through years of automatic buys has dozens of lots with wildly different cost bases. When you donate stock, you want to give away the lots with the lowest basis and the longest holding period, the ones with the biggest embedded gain, because those are the ones creating the most tax liability if you ever sold them.
Do this through specific share identification, not the default. Most brokerages will use FIFO (first-in-first-out) or an average cost method unless you tell them otherwise. Before you initiate the transfer, either use your brokerage’s lot-selection tool or call and specify the exact lots by trade date and share count. Fidelity, Schwab, and most major brokerages support this for a DAF transfer the same way they support it for a regular sale.
This is the mirror image of tax-loss harvesting. Tax-loss harvesting sells your highest-basis, most-underwater lots first to realize losses while keeping the rest of your position. Donating stock does the opposite: give away your lowest-basis, most-appreciated lots first, and keep your higher-basis shares for a future sale (smaller taxable gain) or for your heirs (who get a stepped-up basis at death anyway). Every dollar of embedded gain you donate instead of sell is a dollar of capital gains tax that never gets paid by anyone, ever.
The Rebuy Move
The part that surprises people the first time they hear it: after you donate appreciated shares, you can immediately buy back the same stock with cash, and nothing bad happens.
Say you still want $50,000 of exposure to that same index fund or that same company stock. Donate the $50,000 of appreciated shares to your DAF, then use $50,000 of cash (the cash you would otherwise have used to write a check) to repurchase the identical position the same day. Your portfolio looks exactly the same as it did yesterday. The difference is invisible but valuable: your new shares have a cost basis at today’s price instead of the old, low basis, and the $40,000 of embedded gain that used to live in your position has vanished for good, rather than merely being deferred.
The wash sale rule doesn’t touch this. Wash sale rules only disallow a loss when you sell at a loss and buy substantially identical securities within 30 days. There’s no equivalent rule for gains, and a charitable donation isn’t a sale by you at all, it’s a completed gift. You can repurchase the same ticker the same afternoon with zero wash sale exposure. Confirm the mechanics with your brokerage before you do it at scale, but the rule itself has nothing to say about this.
When to Just Write the Check
This strategy has real edges. Skip it and use cash when:
- You’ve held the shares one year or less. Short-term holdings deduct at the lesser of cost basis or fair market value (IRS Publication 526), meaning you deduct your basis, not the current price. You lose the entire benefit over just donating cash. Wait past the one-year mark first if the timeline allows it.
- The shares are underwater. Never donate a loss position. The built-in loss just disappears; you can’t claim it and neither can the charity. Sell first, harvest the capital loss on your own return, then donate the cash proceeds. You get both the loss deduction and the charitable deduction that way.
- The gift is small. Fidelity Charitable, Schwab Charitable (now branded DAFgiving360), and Vanguard Charitable all charge 0.60% annually on the first $500,000 in your account, and Fidelity’s schedule floors that at $100 a year minimum. On a $1,000 gift, that floor alone is a 10% bite. Below roughly $5,000 to $10,000, the fee math stops working in your favor, unless you use a flat-fee provider like Daffy (see below) or just ask the charity if it can accept stock donations directly into its own brokerage account, which skips the DAF layer entirely.
- It’s private or illiquid company stock. Publicly traded securities skip the qualified appraisal requirement, but pre-IPO shares, restricted private stock, and similar assets don’t get that exception. You’ll need a qualified appraisal, and DAF sponsors often charge extra to accept and eventually liquidate illiquid assets. Daffy, for example, gates private stock contributions to its top $40-a-month tier, and your own brokerage or transfer agent will usually charge for the transfer. It can still be worth doing, it’s just slower and more expensive than a public ticker.
- You don’t itemize at all. If your other deductions are nowhere near the standard deduction and bunching still doesn’t get you there, the fair-market-value deduction advantage disappears, though you still dodge the capital gains tax on the appreciation, which is worth something on its own. One thing that will not save you here: the new above-the-line $1,000 (single) or $2,000 (married filing jointly) charitable deduction for non-itemizers starting in 2026 only covers cash gifts made directly to public charities. It explicitly excludes gifts to donor-advised funds and supporting organizations, and it only reaches organizations described in section 170(b)(1)(A), which leaves out the ordinary private foundation. It never covers stock in any case.
Which DAF, and What It Actually Costs (as of September 2026)
All the major providers use some version of a tiered percentage fee except one flat-fee outlier. These come off each provider’s current published fee schedule.
| Provider | Minimum to open | Minimum grant | Admin fee (first $500K) | Notes |
|---|---|---|---|---|
| Fidelity Charitable | No minimum | $50 | 0.60% or $100, whichever is greater | Investment pool expense ratios range roughly 0.015% to 0.93% depending on the pool; index pools sit near the low end. |
| Schwab Charitable / DAFgiving360 | No minimum | $50 | 0.60% | Rebranded from Schwab Charitable to DAFgiving360 in June 2024, same organization. Professionally managed accounts need a $100,000 minimum and carry an additional advisor fee capped at 1% a year. |
| Vanguard Charitable | $25,000 to open, $5,000 per additional contribution | $500 | 0.60% | A separate organization from DAFgiving360, not the same rebrand. Accounts under $25,000 get hit with a $250 annual maintenance fee on top of the admin fee. Underlying Vanguard fund expense ratios run very low, some pools around 0.02% to 0.03%. |
| Daffy | No minimum | $18 | Flat $3 to $40 per month by membership tier, capped regardless of balance | No percentage fee at all. Underlying fund expense ratios published on Daffy’s portfolios page run from 0.03% to 0.30% across the Conservative, Standard, and ESG options; crypto portfolios go far higher, up to 2.50% on one holding. A 2.9% card-processing surcharge applies to every credit, debit, or Apple Pay contribution, waived only on your first card contribution up to $1,000. |
The flat-fee model matters more than it looks like on paper. A $500,000 DAF balance costs $3,000 a year at Fidelity, Schwab/DAFgiving360, or Vanguard Charitable (0.60%), and $480 a year at Daffy (capped at $40/month). At smaller balances Daffy wins by more, not less: the Supporter tier is free for funds holding under $100, and the Contributor tier runs $36 a year against Fidelity’s $100 floor. The comparison only turns if you contribute heavily into a small balance, because Daffy prices its tiers on annualized contributions rather than account size. Pick based on your contribution volume and how much you care about investment options. The logo on the homepage is the least useful input.
The Money Can Sit There Forever
One thing worth saying plainly: a DAF has no payout requirement. A private foundation must distribute roughly 5% of its assets every year or face an excise tax. A DAF has no such rule. You get your full deduction the moment you contribute, and the money can then sit invested inside the fund indefinitely, years or decades, without ever reaching an actual working charity. Most donors do grant the money out reasonably quickly. Some don’t. That’s a real criticism of the vehicle, and it’s worth knowing before you fund one, even if it doesn’t change the math on whether donating stock beats donating cash.
One caveat on all of the above: these numbers move with your state, your AGI, whether you itemize, and whether your state mirrors the federal charitable deduction at all (several with high rates don’t). The mechanism is solid. Run your own figures past a CPA before you move six figures of stock on the strength of a blog post.
Common Questions
Can I donate RSU shares before they vest?
No. You don’t own unvested RSU shares, so there’s nothing to transfer. Vesting itself is a taxable compensation event regardless of what you eventually do with the shares. You can only donate shares after they’ve vested and settled into your brokerage account.
How long do I need to hold stock before donating it to charity?
More than one year. Shares held one year or less deduct at the lesser of cost basis or fair market value, which erases the tax advantage over donating cash. Past the one-year mark, appreciated stock deducts at full fair market value.
Does donating stock to a donor-advised fund count for the new $1,000 charitable deduction for non-itemizers?
No. The 2026 above-the-line deduction covers only cash gifts made directly to public charities. Contributions to a donor-advised fund, private foundation, or supporting organization are explicitly excluded, and stock donations never qualify since only cash counts.
How much of my income can I deduct for donating stock to charity?
Up to 30% of your adjusted gross income per year for long-term appreciated stock given to a public charity or donor-advised fund, compared to 60% of AGI for cash gifts. Amounts above the limit carry forward for up to five years before they expire unused.
Do I need an appraisal to donate stock to charity?
No. Publicly traded securities are specifically exempt from the qualified appraisal requirement that applies to other noncash gifts over $5,000. You still file Form 8283 (required once total noncash gifts for the year exceed $500), but you skip the appraiser signature entirely.
