Roth Conversion vs. QCD: Which Comes First After 70½?

How qualified charitable distributions and Roth conversions interact after 70½ — the MAGI difference, IRMAA effects, RMD offsets, and how to sequence both in the same year.

Two tools that pull in opposite directions

A Roth conversion deliberately raises this year's taxable income to shrink future taxable income. A qualified charitable distribution does the opposite: it moves IRA dollars to charity without ever appearing in adjusted gross income. Both shrink the pre-tax balance that drives future required minimum distributions, but only one raises the tax bill today — which is why the right order matters once both are available.

The mechanics of a QCD

  • Available from age 70½ — earlier than the RMD start age, which is a planning window.
  • Paid directly from an IRA to a qualifying public charity; donor-advised funds and private foundations do not qualify.
  • Counts toward the year's RMD up to the QCD amount, and is excluded from AGI entirely.
  • Annual per-person limit is inflation-indexed (roughly $108,000 for 2025 and indexed after), and a one-time split-interest election exists.
  • No charitable deduction is claimed — the exclusion from income is the benefit, and it works whether or not you itemize.

Why excluding income beats deducting it

A deduction reduces taxable income; a QCD reduces AGI. AGI drives the taxable share of Social Security, the IRMAA tiers for Medicare Part B and D, the net investment income tax threshold, and several credit phaseouts. Giving $30,000 as a QCD instead of writing a check from a brokerage account can save tax in three places at once for a retiree who would not have itemized anyway.

When the conversion wins

  • Before 70½, when a QCD is not yet available and the bracket is unusually low.
  • Before the two-year IRMAA lookback bites — conversions done by 62 do not raise Medicare premiums at 65.
  • When the heirs face a higher bracket than you do, and the goal is tax-free growth inside a 10-year inherited window.
  • When charitable intent is small relative to the pre-tax balance; a QCD can only shrink the IRA by what you actually give away.

When the QCD wins

  • You are already charitable and already taking RMDs — the QCD satisfies the RMD at a zero tax cost.
  • You are sitting just under an IRMAA tier or the 85% Social Security inclusion threshold.
  • You do not itemize, so a cash gift would produce no federal benefit at all.
  • Your state taxes IRA distributions but follows federal AGI — the exclusion carries through to the state return too.

Sequencing both in the same year

Once RMDs have begun, the first dollars out of the IRA are treated as the RMD, and an RMD cannot be converted. So take the QCD first — early in the year, before any other distribution — to satisfy as much of the RMD as you intend to give. Take any remaining RMD in cash, then convert on top of that up to your ceiling for the year. Set that ceiling below the next IRMAA tier rather than at a bracket top, since the surcharge is a cliff and the bracket is not.

A worked shape

Suppose a married couple at 74 has a $60,000 RMD, gives $25,000 a year to their church, and has room of $40,000 before the first IRMAA tier. Giving by check leaves $60,000 of RMD in AGI and no conversion room left. Giving by QCD removes $25,000 from AGI, leaves $35,000 of RMD to report, and frees roughly $40,000 of headroom for a conversion that shrinks every future RMD — the same charitable gift, one fewer surcharge, and a smaller pre-tax balance for the survivor and the heirs.

Common mistakes

  • Taking the RMD in January, then trying to QCD in December — the RMD is already satisfied and taxable.
  • Having the custodian mail the check to you instead of the charity, which breaks the exclusion.
  • Forgetting that the 1099-R does not flag QCDs; the exclusion has to be reported on the return.
  • QCDs from a SEP or SIMPLE that is still receiving contributions, or from a 401(k) — neither qualifies.
  • Deducting the gift as well as excluding it. You get one or the other, never both.
