Before You Take Your 401(k) RMD, Make Sure You Know About This Tax-Free Charitable Strategy

A 73-year-old with roughly $1.6 million in a former employer’s 401(k) faces a first-year required minimum distribution near $60,000, yet doesn’t need the money for living expenses. Social Security and a modest pension cover the bills. The IRS clock has started, and the withdrawal is coming whether wanted or not.

A legal move makes the entire RMD disappear from taxable income. Most 73-year-olds with sizable 401(k) balances never use it because it has a paperwork trap that trips them up in the first year, when it matters most.

The QCD Rule and the 401(k) Trap

A qualified charitable distribution lets anyone age 70½ or older send up to $111,000 in 2026 from a retirement account straight to a qualifying charity. The gift counts toward the RMD, and none of it lands on the Form 1040: not as adjusted gross income, not as modified AGI, not anywhere on the return.

Here is the trap. QCDs can only come from an IRA. A 401(k) does not qualify, nor does a 403(b) or 457. If the entire $1.6 million sits in a former employer’s plan, a check written to charity from that plan is a taxable distribution first, then a separate charitable deduction on Schedule A that most retirees cannot itemize thanks to the standard deduction.

The fix is a direct trustee-to-trustee rollover of the 401(k) into a traditional IRA, completed by December of the year before the RMD year begins. Once the balance sits in an IRA, the custodian can cut checks payable directly to charities, coded as a QCD on the resulting 1099-R.

Why Zeroing the RMD Beats Simply Taking It

For a retiree who plans to give to charity anyway, the QCD is close to free money. The real prize is what it prevents further down the tax return.

Consider a married couple, both 73, both on Medicare, with $50,000 in combined Social Security, a $20,000 pension, and around $30,000 in dividends and interest. Their income is already high enough that up to 85% of their Social Security is taxable. Layering a $60,377 RMD on top (dividing $1.6 million by the age-73 Uniform Lifetime divisor of 26.5) pushes ordinary income past $160,000, triggering two consequences.

First, IRMAA. The 2026 Medicare tiers begin at $109,000 for singles and $218,000 for joint filers. A couple crossing $218,000 in modified AGI pays an extra $60.40 per person per month on Part B, plus a Part D surcharge. Over a full year, that is more than $1,400 in premium hikes, and IRMAA looks back two years, so the surcharge lands on 2028 premiums.

Second, ordinary income tax. A $60,000 withdrawal in the 22% federal bracket is $13,200 owed, plus state tax almost everywhere. Route the same $60,000 as a QCD, and the RMD is satisfied, modified AGI stays under the IRMAA threshold, the Social Security taxation ratio does not worsen, and the couple keeps the standard deduction. Total tax on the RMD: zero.

The 10-year Treasury yields 4.69% right now, close to a 12-month high. That is the return given up on any dollar sent to charity rather than reinvested. For a giver who was writing checks anyway, the math is a wash. For someone who was not, the QCD is the wrong tool.

Three Moves to Make Before Year-End

1. Roll the 401(k) into a traditional IRA now. Use a direct trustee-to-trustee transfer to avoid 20% mandatory withholding and 60-day rollover risk. The IRA must be established and funded before any QCD check is written.
2. Run the RMD math against the IRS Uniform Lifetime Table. At age 73, the divisor is 26.5, so a $1.6 million balance produces a required distribution of roughly $60,377. Size QCD gifts up to that number to fully offset the taxable withdrawal. Anything above the RMD still counts as a QCD but does not deliver additional RMD relief.
3. Instruct the custodian to make checks payable to the charity directly. A check payable to you first, then endorsed to the charity, becomes a taxable distribution. The check must name the charity’s exact legal entity, and confirm the custodian codes the 1099-R properly. The $111,000 QCD limit is per person, so a married couple with separate IRAs can direct up to $222,000 combined in 2026 against their respective RMDs.

If combined income is already flirting with the first IRMAA tier, the tax savings on a single year of coordinated QCDs typically covers a fee-only planner’s bill several times over. That is the trigger for professional help.
