An $42,000 RMD Lands 11 Years After a Pension Made It Easy
A pension paid every bill for 11 years while $650,000 sat untouched in two IRAs. At 73, the first required minimum distribution arrived at $42,000 — and the tax bill was the smaller problem.
A couple who retired at 62 with $650,000 across two traditional IRAs and lived on his pension for 11 years faced a first required minimum distribution of $42,000 at age 73, stacked on top of pension income they were already spending.
There is a particular kind of retirement that looks flawless for a decade and then presents its invoice all at once. A couple stopped working at 62 with $650,000 spread across two traditional IRAs. His pension covered the bills — all of them — so the IRAs were never touched. Eleven years later, at 73, the first required minimum distributions arrived and came to $42,000, landing on top of a pension that was already fully taxable.
Nothing went wrong here. No market crash, no bad advisor, no overspending. The couple did what conventional advice tells people to do: spend the guaranteed income first and let the tax-deferred account compound. The problem is that tax deferral is a loan from the IRS, and the IRS sets the repayment schedule.
Why the Forced Withdrawal Is the Least of It
A required minimum distribution, or RMD, is the amount the IRS makes you pull out of a traditional IRA or 401(k) each year once you hit the trigger age — currently 73 for this cohort. The amount is not your choice. It is the prior year-end balance divided by a life-expectancy factor from an IRS table. Because the divisor shrinks every year while the balance may keep growing, the required percentage climbs with age.
The $42,000 itself is not the injury. If the couple did not need the money, they could reinvest it in a taxable brokerage account after paying the tax. The damage is what the $42,000 does to every other line on the return.
Ordinary income from an RMD stacks on top of pension income. That can:
- Push the couple into a higher marginal bracket, so the last dollars of the distribution are taxed at a rate they never paid while working part of their career.
- Increase the share of Social Security benefits that is taxable, because the formula counts other income when deciding how much of the benefit is included.
- Trigger IRMAA — the Income-Related Monthly Adjustment Amount — which raises Medicare Part B and Part D premiums for both spouses based on income from two years earlier.
- Raise the income figure used for other phase-outs, from capital-gains treatment to state-level credits.
IRMAA is the one that surprises people, because it is a cliff, not a slope. Cross a threshold by a single dollar and the surcharge applies to the entire year, for each spouse, with a two-year lag between the income and the premium. A one-time spike — a property sale, a Roth conversion done too aggressively — echoes into Medicare bills long after the money is spent.
The Eleven Quiet Years Were the Decision
The interesting window in this story is not age 73. It is ages 62 through 72.
During those 11 years, the couple's taxable income was, by the account given by 24/7 Wall St, essentially the pension and nothing else. For many retirees, that stretch between the end of wages and the start of RMDs is the lowest-bracket period of their adult lives. It is also the only period in which they have full control over how much income to recognize.
That window is where partial Roth conversions live. Converting a slice of a traditional IRA to a Roth means paying tax now, voluntarily, at a rate you choose by sizing the conversion. The converted money then grows tax-free and — critically — is never subject to RMDs. Done in measured annual amounts that fill up a bracket without spilling into the next one, conversions shrink the balance that the IRS will later force out.
The couple in this case let 11 years of that window pass unused. Every dollar of growth in those IRAs stayed on the taxable side of the ledger, and the balance that eventually produced a $42,000 first-year RMD was larger for it.
What Can Still Be Done After 73
Once RMDs begin, the menu narrows, but it is not empty.
Every dollar of growth in those IRAs stayed on the taxable side of the ledger, and the balance that eventually produced a $42,000 first-year RMD was larger for it.
Qualified charitable distributions. A QCD sends money directly from an IRA to a qualified charity. It counts toward the RMD but never appears as income on the return, which means it does not inflate the Social Security inclusion calculation or push anyone over an IRMAA line. For a retiree who already gives to charity, routing that giving through the IRA instead of a checking account is close to a free upgrade.
Conversions above the RMD. RMDs cannot themselves be converted, but once the required amount is taken, additional dollars can still move to a Roth. The math gets harder because the RMD has already filled part of the bracket, but for a couple worried about the survivor's future filing status, it can be worth it.
Watching the single-filer cliff. This is the risk nobody plans for. When one spouse dies, the survivor typically files as a single taxpayer, where brackets are narrower and IRMAA thresholds lower. A pension may drop, or it may not, depending on the survivor election — but the IRA balance does not shrink, and the RMD on it lands on a single return. Households with a large pension and a large IRA are exactly the ones this hits hardest.
Asset location. If the RMD is not needed for spending, where it goes next matters. Reinvested into a taxable account, it can be held in tax-efficient index funds so that future growth is taxed at capital-gains rates rather than ordinary rates, and receives a step-up in basis for heirs.
The Backdrop Investors Are Compounding Into
The balances that produce large RMDs are built by long equity runs, and the market has been kind to buy-and-hold retirees. At the most recent close on Friday, 18 September 2026, the S&P 500 tracker SPY finished at $761.69, down 0.12% on the day from a prior close of $762.60. The Nasdaq 100 fund QQQ closed at $721.45, up 0.63%, while the Dow tracker DIA ended at $515.88, off 0.48%.
A decade of that kind of compounding inside a tax-deferred account is a good problem in the arithmetic sense and a real one in the tax sense. The larger the balance grows untouched, the larger the mandatory withdrawal, and the more room there is for a single year's income to cross a threshold the retiree never thought about.
What to Check Before the Window Closes
For anyone currently between retirement and age 73 with a pension, an annuity or another income source covering expenses, the practical review is short:
- Project the traditional IRA balance forward to the RMD start age and estimate what the first required distribution would look like against current income.
- Model the year one spouse files as a survivor, not just the joint years.
- Identify the top of the bracket you are comfortable filling each year, and decide whether to fill it with a conversion.
- Mark the two-year IRMAA lag on the calendar, because income recognized now sets Medicare premiums later.
None of that changes the $42,000. It changes whether the next household reading this story ends up with the same letter.
Frequently asked questions
What is a required minimum distribution?
An RMD is the amount the IRS requires you to withdraw each year from a traditional IRA or 401(k) once you reach the trigger age, currently 73 for this cohort. It is calculated by dividing the prior year-end account balance by a life-expectancy factor from an IRS table. The withdrawal is taxed as ordinary income, and the required percentage rises as you age.
Why was a $42,000 RMD a problem if the couple didn't need the money?
Because the distribution is taxable whether or not it is spent. Stacked on top of an already-taxable pension, it can push the household into a higher bracket, increase the share of Social Security benefits subject to tax, and raise Medicare Part B and Part D premiums through the IRMAA surcharge. The unwanted income, not the withdrawal itself, does the damage.
What is IRMAA and why does it matter here?
IRMAA is the Income-Related Monthly Adjustment Amount, a surcharge on Medicare Part B and Part D premiums for higher-income beneficiaries. It works as a cliff: crossing a threshold by one dollar applies the surcharge for the full year, per spouse. It uses income from two years earlier, so a single large RMD or conversion raises premiums with a lag.
How would Roth conversions have helped this couple?
Converting portions of a traditional IRA to a Roth during the low-income years between retirement at 62 and the RMD start age lets you pay tax voluntarily at a rate you control by sizing the conversion. Roth accounts are not subject to RMDs, so each conversion permanently shrinks the balance the IRS will later force out as taxable income.
What is a qualified charitable distribution?
A QCD moves money directly from an IRA to a qualified charity. It counts toward satisfying the required minimum distribution but is excluded from taxable income entirely, meaning it does not inflate the figures used for Social Security taxation or Medicare IRMAA thresholds. For retirees who already donate, giving through the IRA is more tax-efficient than writing a check.
Why does the death of one spouse make RMDs more expensive?
The surviving spouse generally files as a single taxpayer, which uses narrower tax brackets and lower IRMAA thresholds than married filing jointly. The IRA balance and its required distribution do not shrink, so the same withdrawal is taxed under harsher rules. Households with both a large pension and a large IRA face the steepest version of this problem.
