QCD vs RMD at 73: $40K Donation Beats the Deduction

The decision, resolved with numbers

Meet Robert and Linda, both 73, married filing jointly, living in Phoenix, Arizona. Robert has a $1,000,000 traditional IRA. They give $40,000 a year to their church and a local food bank — gifts they make regardless of tax treatment. Their other income: $52,000 in combined Social Security benefits and $18,000 from a small pension. They do not itemize; their deductible expenses fall well under the 2026 MFJ standard deduction of $31,500.

At 73, Robert’s required minimum distribution is mandatory. The only real question is how the $40,000 of giving interacts with that RMD. Two paths:

• Path A — QCD: direct $40,000 from the IRA custodian to the charities under IRC §408(d)(8). It satisfies the RMD and is excluded from AGI.
• Path B — RMD then deduct: take the $40,000 RMD into income, then write a $40,000 check and try to deduct it.

Path A wins, and it isn’t close. Because Robert and Linda take the standard deduction, the charitable check in Path B produces zero tax benefit — their itemized total still falls below $31,500. So Path B leaves $40,000 of fully taxable RMD on the return with no offset. Path A removes that same $40,000 from AGI entirely. The gap between the two is the entire tax on a $40,000 RMD, plus IRMAA and Social Security ripple effects.

What a QCD actually is

A Qualified Charitable Distribution lets an IRA owner who is 70½ or older transfer money directly from a traditional IRA to a qualifying public charity. The defining feature is in the statute: the distribution is excluded from gross income — it never appears as taxable income on Form 1040. You report the gross IRA distribution on line 4a and write “QCD” next to a taxable amount of $0 on line 4b.

The rules that make or break a QCD:

1. Age 70½. You must have reached 70½ on the date of the transfer — not just the year you turn 70½. This is older than the RMD start age of 73, so you can do QCDs for the years between 70½ and 73 before RMDs even begin.
2. Direct transfer. The money must go from the IRA custodian directly to the charity. If the check is made out to you and you forward it, the exclusion is lost. Most custodians issue a check payable to the charity that you can deliver.
3. Qualifying charity. A 501(c)(3) public charity. Donor-advised funds and private foundations do not qualify — this trips up more people than any other rule.
4. $108,000 annual cap (2026). The original $100,000 limit is now indexed for inflation under SECURE 2.0 §307. Each spouse has a separate cap from their own IRA.
5. Traditional IRA only. QCDs come from IRAs, not 401(k)s. Roll a 401(k) to an IRA first if you want to QCD from it.

Why an AGI exclusion beats a deduction

This is the heart of the matter, and most retirees get it backwards. A deduction and an exclusion are not the same instrument, and the difference is worth real money.

A deduction reduces taxable income — but only after AGI is already locked in, and only if you itemize above the standard deduction. An exclusion keeps the dollars out of AGI in the first place. AGI is the number that feeds almost every other calculation on the return: Medicare IRMAA, the taxable portion of Social Security, the 3.8% net investment income tax threshold (IRC §1411), medical-expense floors, and more. Lower AGI is structurally more valuable than a same-size deduction.

The math: $1M IRA, $40,000 gift at 73

At age 73, the Uniform Lifetime Table divisor (IRS Pub. 590-B, Table III) is 26.5. On Robert’s $1,000,000 prior year-end balance, the RMD is $1,000,000 ÷ 26.5 = $37,736. The $40,000 QCD fully covers it — the extra $2,264 above the RMD is still a valid QCD and still excluded.

Path B adds roughly $4,800 in federal tax at the 12% MFJ bracket and another ~$1,000 in Arizona state tax (a 2.5% flat rate), before the cascade effects below. Path A adds none of it. For a gift they were making anyway, choosing the QCD is worth roughly $5,800+ in year one — and more if the extra $40,000 of AGI also tips them into a higher IRMAA tier.

The cascade: IRMAA and Social Security

The headline tax saving understates the QCD’s value, because AGI drives two expensive secondary calculations.

Medicare IRMAA

Medicare Part B and Part D surcharges (the Income-Related Monthly Adjustment Amount) are set by MAGI from two years prior. For 2026 premiums, the first MFJ surcharge tier starts at $206,000 of MAGI. A retiree near that line who adds a $40,000 RMD to AGI can cross it — jumping the Part B base of $185/month to $259/month each, plus a Part D surcharge of $13.70/month. For a couple, crossing one tier costs roughly $2,105/year in extra premiums ($87.70/month each × two × 12). The QCD keeps the $40,000 out of MAGI and off the IRMAA ledger entirely.

Social Security taxation

How much of your Social Security is taxable depends on “combined income” — AGI plus tax-exempt interest plus half of your benefits. The MFJ thresholds are $32,000 (up to 50% of benefits taxable) and $44,000 (up to 85% taxable), and critically they are not indexed for inflation — they have been frozen since 1983. Adding a $40,000 RMD to combined income can push a larger share of Social Security into the 85% taxable zone. A QCD, because it stays out of AGI, leaves combined income where it was and protects that benefit.

What most people get wrong

The single most common myth: “I’ll just take the RMD and deduct my donation — same thing.” It is not the same thing, for three reasons.

• The standard deduction usually erases the write-off. About 90% of households take the standard deduction ($31,500 MFJ in 2026). If your itemized total is below that, your charitable check buys you exactly nothing. The QCD works regardless of whether you itemize.
• A deduction never touches AGI. Even for an itemizer who clears the standard deduction, the deduction reduces taxable income but not AGI — so IRMAA and Social Security taxation still see the full RMD. The QCD reduces AGI itself, which is the only number those tests read.
• The 60%-of-AGI charitable ceiling can clip the deduction. Cash gifts are deductible only up to 60% of AGI (IRC §170(b)). A QCD has no such percentage limit — only the $108,000 annual cap. High-giving retirees can deduct less than they gave, but a QCD excludes every qualifying dollar.

A second myth: “QCDs are only for the wealthy.” The opposite is true. The QCD is most valuable for the modest-income retiree who takes the standard deduction and is sensitive to IRMAA and Social Security thresholds — exactly the people a charitable deduction was never going to help.

The one trap: the QCD “anti-abuse” offset

SECURE 2.0 created one interaction worth knowing. If you make a deductible IRA contribution after age 70½ (allowed since the SECURE Act removed the age cap on contributions), the IRS reduces the tax-free portion of your future QCDs dollar-for-dollar by the cumulative post-70½ deductible contributions you’ve made. For most retirees who are no longer working and not contributing, this never applies. But if you have earned income and are still funding a deductible IRA, coordinate carefully — you cannot both deduct the contribution going in and exclude it via QCD going out.

How to execute a QCD cleanly

1. Confirm you’re 70½+ on the transfer date and that the gift goes to a 501(c)(3) public charity (not a DAF or private foundation).
2. Instruct your IRA custodian to send funds directly to the charity — never have the check made payable to you. Many custodians offer IRA checkbooks for this purpose; just ensure the check clears by December 31.
3. Do the QCD before any other IRA withdrawal that year. The first dollars out of the IRA count toward the RMD. If you take a regular distribution first, you cannot retroactively convert it to a QCD.
4. Get a contemporaneous written acknowledgment from the charity, same as any donation — the QCD still requires it.
5. Report it correctly: gross distribution on Form 1040 line 4a, taxable amount $0 on line 4b with “QCD” noted. The Form 1099-R will show the full distribution; the exclusion is something you claim on the return.

The decision lever

If you are 70½ or older, hold a traditional IRA, give to charity, and take the standard deduction, the QCD is the right tool essentially every time — the itemized-deduction path gives you nothing while the QCD keeps the entire gift out of AGI. The single number to watch is your projected AGI against the next IRMAA tier and the Social Security taxation thresholds: the closer you sit to a line, the more a $40,000 exclusion is worth versus a $40,000 deduction. Route the gift through the IRA, satisfy the RMD with it, and keep the income off the return in the first place.
