The $108,000 IRA-to-Charity Move That Can Save More on Medicare Than on Your Tax Bill

A Qualified Charitable Distribution looks, on the surface, like a minor administrative variant of “take the RMD, then donate the cash.” The mechanics are almost identical. The tax outcome is not — and for many retirees, the biggest part of the benefit isn’t even the line normally associated with the strategy.

Two paths, same donation, different tax outcome

Take RMD, then donate QCD directly from IRA
RMD requirement satisfied Yes Yes
Counts as taxable income Yes — full RMD No — QCD amount excluded from AGI
Deduction available Only if itemizing Not applicable — already excluded
AGI impact Increases by full RMD Unchanged

For someone taking the standard deduction — roughly 90% of filers since the 2017 tax law nearly doubled it — the “take then donate” path gets zero tax benefit from the donation itself; the RMD is simply taxable income with no offsetting deduction. The QCD sidesteps that entirely by never counting the donated amount as income in the first place.

Where the real money is: AGI-tested benefits

The direct tax saved from a QCD is straightforward — it’s roughly the QCD amount times the marginal rate that would otherwise have applied to that portion of the RMD. But AGI itself is a gatekeeper for several other retiree-specific costs and benefits, and this is where the QCD’s advantage compounds well past the headline number:

  • Medicare IRMAA. Higher Modified AGI pushes Medicare Part B and Part D premiums into surcharge brackets, starting at $106,000 (single) / $212,000 (MFJ) MAGI in 2025. A QCD that keeps MAGI below one of these thresholds can save far more in avoided premium surcharges than in direct income tax.
  • Social Security taxability. Up to 85% of Social Security benefits become taxable as “combined income” (AGI plus certain add-backs) rises. Lower AGI from a QCD can reduce how much of an existing Social Security benefit gets taxed at all.
  • ACA premium tax credits. For retirees not yet on Medicare and using ACA marketplace coverage, lower MAGI preserves more of the premium tax credit.

For a retiree sitting near one of the IRMAA thresholds, the avoided premium surcharge alone can exceed the direct income-tax savings from the QCD — meaning the “real” value of the strategy is frequently larger than what shows up as tax saved on the return itself.

Where this strategy doesn’t apply

  • You’re under 70½. The QCD authority specifically starts at 70½, even though RMDs themselves don’t begin until 73 under SECURE 2.0 rules. Between 70½ and 73, QCDs are available even without an RMD requirement to satisfy, but the strategy is less compelling without an RMD to offset.
  • You take the standard deduction and don’t plan to donate anyway. The QCD is a tax-efficient way to fund donations you’d make regardless — it’s not a reason to increase giving purely for tax purposes. Treat it as reshaping existing charitable intent, not creating new intent.
  • The charity isn’t QCD-eligible. Donor-advised funds and private foundations generally don’t qualify as QCD recipients, even though they’re eligible for regular itemized charitable deductions. Confirm the specific charity’s eligibility before initiating the transfer.
  • You’re nowhere near an IRMAA threshold. The AGI-side benefits are the larger part of the QCD’s value specifically for retirees near a MAGI cliff. Someone with income well below any threshold still gets the direct tax benefit, but not the outsized secondary savings.

What to actually do

  1. Confirm you’re 70½ or older and identify a QCD-eligible public charity (not a donor-advised fund or private foundation).
  2. Check your current MAGI against the 2025 IRMAA thresholds ($106,000 single / $212,000 MFJ) — if you’re near one, the QCD’s value is likely larger than the direct tax math alone suggests.
  3. Route the transfer directly from the IRA custodian to the charity — the funds must never pass through your hands for the QCD treatment to apply.
  4. Keep the charity’s written acknowledgment; QCDs still require substantiation even though there’s no itemized deduction to claim.
  5. If married with separate IRAs, consider whether both spouses can use their own $108,000 QCD limit for a combined donation strategy.
