A donor-advised fund is a giving account run by a sponsoring charity, and Modera Wealth Management sets one up by choosing which long-held taxable shares to give and timing the gift for a high-income year. Waiting until after your last paycheck is costly, because the IRS caps a stock gift at 30 percent of adjusted gross income (AGI), so a $76,600 gift may only yield $24,000 of deduction a year. Each deducted dollar also saves less at a lower assumed rate once that income ends.
Usually it starts with a question you can't answer. A spouse or an adult child asks, 'If we give every year anyway, why not give the stock that has doubled instead of cash?' You know the RSUs vest, the ESPP buys every period, and one stock is too big a share of what you own. But you don't know which shares to give, or by when. Modera Wealth Management works through that with you before the date passes.
Does donor-advised fund setup matter if you're 10 to 15 years from retiring?
Yes, if you give every year and your salary, RSU vests and ESPP purchases will stop on a known date. The years with a full paycheck are when a deduction is worth the most, and that window closes at a date you can already name. For Heather, a hypothetical 52-year-old engineering manager, that date is 55.
In practice, setup is four tasks. You open the account with a sponsoring charity, name a successor advisor, move a long-held appreciated lot in kind from the taxable account, and record the basis and purchase date for Form 8283, the IRS form for noncash gifts.
Our habit comes from asset location, the idea that which account holds which investment matters as much as what you own. Before suggesting any lot, Modera Wealth Management lists every taxable holding with its basis and holding date. A low-basis stock index fund usually goes before the bond funds sitting in taxable, because bond funds have little gain to wipe out. Giving the stock lot also frees up taxable-account room to move holdings around.
Money inside the fund can stay invested and grow without tax until you recommend grants. A gift made at 52 can keep paying for your yearly giving well past 55. Gifts are irrevocable, so give only money you won't need for the retirement budget. Every investment can lose value, including the shares inside the fund.
Is waiting to fund a donor-advised fund costly once the paycheck stops at 55?
Yes. Giving now and giving at 54 come out close, but giving at 57 after leaving work cuts the saving, because only 30 percent of AGI counts each year and the assumed rate falls. Heather's numbers show it: the same lot saves about $19,200 if she gives it now and at most about $16,850 if she waits until 57.
For illustration, take Heather (hypothetical), 52. She already itemizes and holds an index-fund lot in her taxable account worth $60,000 with a $20,000 basis. She plans to leave work at 55. We compare three gift dates on the same points: lot value, assumed federal rate, the 30 percent cap and total saving.
Gift now: at an assumed 32 percent federal rate, $60,000 × 0.32 = $19,200 saved, and the $40,000 gain is never taxed. Gift at 54, still working: assuming 5 percent a year, $60,000 × 1.1025 = $66,150; × 0.32 = about $21,170. The 54 figure is higher only because the lot grew.
Gift at 57, after she leaves at 55: $60,000 × 1.276 = about $76,600. With $80,000 of AGI, only 30 percent, or $24,000, counts each year. Spread over four years ($24,000, $24,000, $24,000, $4,600) at an assumed 22 percent, it saves at most about $16,850. The remainder carries forward for five years.
The carryforward only helps if Heather itemizes in every one of those later years. Her single-filer standard deduction for 2026 is $16,100, so a retiree whose other deductions fall away can lose part of the benefit.
Shortcut: if more than half of your planned lifetime giving happens after your income drops, move a block of it into the fund in your last two full working years. These are illustrations, not forecasts.
Three gift dates compared
What the cap does after 55
If your income will drop when you stop working, fund the donor-advised fund while the paycheck still comes in. Use shares held more than one year, and keep the gift at or under 30 percent of that year's AGI.
| Gift date | Lot value | Assumed rate | Total saving |
|---|---|---|---|
| Now, age 52 | $60,000 | 32% | $19,200 |
| Age 54, working | $66,150 | 32% | about $21,170 |
| Age 57, retired | about $76,600 | 22% | at most $16,850 |
Five answers to get from anyone setting up your donor-advised fund
Ask these before you sign with Modera Wealth Management or anyone else.
- Which of my lots have been held more than one year
- What the transfer form must say about delivering shares in kind
- How large a gift fits under 30 percent of this year's AGI
- What the fee is, in a written agreement signed before work begins
- Who receives the sponsor's receipt letter and prepares Form 8283 in April
Does a donor-advised fund change your RSU, ISO and concentrated stock plans?
Yes, it touches all three. For concentrated stock diversification, employer shares held more than a year can go into the fund in kind, which shrinks the position without a sale. For RSU tax planning, a year with a large vest is a natural year to fund the account.
For ISO exercise planning, check how the deduction interacts with the alternative minimum tax before sizing the gift. Modera Wealth Management reviews all three on the same tax projection.
Same question at 34 and at 52, two different answers
Tuan (hypothetical), 34, and Heather (hypothetical), 52, both ask whether to open a donor-advised fund this year. Heather gets a yes: she already itemizes, she has a $60,000 index-fund lot with a $20,000 basis, and her paycheck ends in three years. Tuan gets a not yet. He rents, takes the $16,100 standard deduction, gives a few thousand dollars annually, and his first job is cutting $900,000 of employer stock down to a fifth of his net worth. He should look at the fund again when his yearly giving plus other deductions clearly passes the standard deduction.
Which ages change the rules for giving while you work?
Several ages between 50 and 75 change what a gift does for you, and the biggest is 55, when the paycheck ends. The IRS sets these rules for 2026; the table shows where each one touches giving.
One mistake costs real money. An instruction to sell the lot and wire cash to the sponsor turns a tax-free gift into a realized $40,000 gain on Heather's 1099-B. That is about $6,000 of tax bill at an assumed 15 percent rate. It can't be undone once the trade settles, because the gift is irrevocable. The transfer form has to say deliver in kind and name the lot. The only remedy is to give a different appreciated lot next time.
Skip the donor-advised fund if your itemized deductions, counting the gift, won't land clearly above the $16,100 single standard deduction. It also doesn't fit money you might need before retirement, because the sponsor legally controls everything you put in.
Why the cap matters most
The sale-and-wire mistake
| Age | What switches on | What it means for giving |
|---|---|---|
| 50 | $8,000 401(k) catch-up begins | Pre-tax deferrals lower AGI and the 30% cap |
| 55 | Penalty-free 401(k) withdrawals after leaving | Paycheck ends; deduction worth less |
| 60–63 | $11,250 higher catch-up | Applies only if still working |
| 63 | Income sets age-65 Medicare premium | Gift deduction does not lower MAGI |
| 70½ | IRA qualified charitable distributions allowed | QCDs cannot go to a donor-advised fund |
| 75 | RMDs start if born 1960 or later | QCDs to charities can count toward RMD |
Four decisions Modera Wealth Management walks through, first call to first grant
First call: you list what you give each year and when you expect to stop working, then decide whether the giving is large enough to bunch. Before any work starts, the fee is set out in a written agreement for you to sign. Lot review: the team works from your brokerage year-end statement and cost-basis records. You decide which lot goes and how large the gift is, measured against 30 percent of the year's projected AGI.
Account opening: you pick the sponsor, name a successor and choose how the fund's money is invested. The in-kind transfer form names the specific lot, and it should go in well before the December holiday rush at brokerages. After the transfer, the sponsor's receipt letter arrives, Form 8283 goes in with the April return, and you start recommending grants on whatever schedule you like.
The years with a full paycheck are when a deduction is worth the most.
What people ask about a donor-advised fund
What does Form 8283 ask for when I give index-fund shares to a donor-advised fund?
The IRS asks for a description of the shares, the date you bought them, your cost basis and the fair market value on the gift date. Record the purchase date and basis before the transfer. The sponsor's receipt letter supports the value, and the form goes in with your April return.
How soon before my last day at work should I move shares into a donor-advised fund?
Move them at least one full tax year before your last paycheck, and earlier if you can. The in-kind transfer takes time at the brokerage, and December is crowded. Your deduction is worth the most while your income is still high, so the last two working years are the window.
How long can money sit in a donor-advised fund before it has to go to a charity?
Federal law sets no fixed number of years, but each sponsor writes its own rules on minimum activity or grant size. Check your sponsor's policy before opening the account. Money inside can stay invested and grow without tax until you recommend grants, and every investment can lose value.
Does a gift to a donor-advised fund lower the income Medicare uses to set my premium at 65?
No. Medicare sets your premium from modified adjusted gross income reported two years before, and an itemized charitable deduction doesn't reduce that number. The income-related brackets start above the $202.90 standard Part B premium for 2026 and depend on that figure. A qualified charitable distribution from an IRA can differ.
