For most of their careers, the goal was clear: contribute as much as possible to tax-deferred accounts and let it compound. That discipline built real wealth. Now, for many pre-retirees sitting on seven-figure IRA balances, that same discipline is building a future tax problem the IRS will eventually collect on their schedule, not yours.

Required Minimum Distributions begin at age 73 under current law. For a 60-year-old with $2.25 million in a traditional IRA today, the question is not whether to take money out before age 73. The question is how much, in which years, and through which mechanism. The answer matters more than most people expect.

What the IRS Actually Forces at 73

The RMD calculation is straightforward: divide your prior December 31 account balance by the IRS Uniform Lifetime Table factor for your age. At 73, that divisor is 26.5 — meaning roughly 3.77% of the account must be distributed annually. At 80, the factor drops to 20.2, pushing the required percentage to nearly 5%.

On paper, those percentages sound manageable. On a $4 million IRA — what $2.25 million grows to at 6% over 12 years — a 3.77% RMD produces a first-year distribution of approximately $150,800. Add a spouse's RMD, Social Security for both, and brokerage dividends, and a couple's taxable income at 73 can easily land between $200,000 and $300,000. That is firmly in the 32% to 35% brackets, plus IRMAA Medicare surcharges, plus 85% of Social Security benefits fully included in taxable income.

This is not a hypothetical. It is the mathematical outcome of doing nothing.

A Real Situation

David, 61, and Carol, 60, retire in 2028 with $3 million in investable assets: $2.25 million in pre-tax accounts, $600,000 in a taxable brokerage, and $150,000 in Roth IRAs. Their earned income drops to zero in their first year of retirement.

If they follow the path of least resistance — living off the brokerage account, deferring IRA distributions until required — their tax picture at 73 looks like this: David's IRA alone, growing at 6% for 12 years, reaches approximately $4.5 million. First-year RMD: roughly $169,800. Add Carol's IRA, Social Security for both spouses, and brokerage income, and their combined taxable income approaches $280,000 to $320,000. They are in the 32–35% bracket for the rest of their lives, with limited ability to change it.

IRMAA surcharges at that income level add approximately $3,000 to $6,000 per year in Medicare premiums per person — a tax by another name, triggered automatically and difficult to undo.

The Case for Intentional Early Distributions

The alternative is to treat the years from 2028 to 2035 as a deliberate drawdown window. Rather than letting pre-tax accounts compound untouched, David and Carol take intentional distributions — and in many years, convert a portion to Roth — to reduce the future RMD burden while their marginal rate is lower than it will be at 73.

In 2028, with zero earned income, they can take an IRA distribution of $130,000 and remain in the 22–24% federal bracket (using 2026 rates adjusted for inflation). Over 8 years of strategic distributions and conversions averaging $120,000–$150,000 per year, they reduce the pre-tax balance from $2.25 million to roughly $1.4–$1.6 million before RMDs begin.

At 73, a $1.5 million IRA produces a first-year RMD of approximately $56,600 — a far more manageable income event that may keep them entirely within the 22% bracket even after Social Security begins.

The tax paid on each conversion or distribution during this window is real. But it is paid at 22–24% rather than 32–35% on a much larger balance. The differential, compounded over 20 years of retirement, can represent $300,000 to $500,000 in after-tax household wealth.

Roth Conversion vs. Straight Distribution

Both approaches reduce the pre-tax balance and the future RMD. The distinction is where the money goes.

A straight IRA distribution is spent on living expenses or redeployed into the taxable brokerage account. A Roth conversion moves the same dollars into a tax-free account where they compound indefinitely without income tax and without ever triggering another RMD.

For David and Carol at 60–61 with potentially 30-plus years ahead, the Roth conversion is generally the stronger move if they do not need the cash immediately. Each dollar converted reduces future RMDs, grows tax-free, and passes to heirs in a far more favorable form than a pre-tax IRA.

One important rule: the tax on a conversion should come from the taxable brokerage account, not from the IRA itself. Paying conversion taxes from outside the IRA preserves the full converted amount inside Roth. If the tax is withheld from the IRA distribution, that withholding counts as a distribution too — it never makes it into Roth, and it may trigger its own tax implications if not handled correctly.

If they convert $120,000 in 2028 and pay the resulting federal tax of approximately $25,000–$28,000 from brokerage funds, the full $120,000 compounds tax-free. Over 20 years at 6%, that single conversion becomes approximately $384,000 inside Roth — entirely outside the reach of the IRS.

When It Does Not Make Sense

Not every pre-retiree should pursue aggressive pre-RMD conversions. If retirement income remains elevated due to consulting work, rental income, or part-time practice, filling the 22% bracket may require pushing immediately into 32%. In that scenario, a more modest strategy targeting specific bracket slots is more appropriate than maximum annual conversions.

Additionally, significant flexibility remains about the future of federal tax rates. The TCJA-era brackets are currently extended through 2026 and beyond pending congressional action, but long-term rate certainty does not exist. Households with high state tax burdens — or those with legitimate reasons to expect lower future income — may reasonably scale back conversion aggressiveness.

The Fundamental Point

Deferring IRA distributions until 73 is the default. It requires no decision, no planning, and no action. That is precisely why most households do it — and precisely why it often produces the worst after-tax outcome.

Taking intentional distributions before RMDs begin is not aggressive. It is the exercise of the one form of tax control you actually have over a liability the IRS will otherwise collect on the largest possible balance, at the least convenient time, at the highest available rate.

The window opens at retirement. For David and Carol, that is 2028. It closes at 73. Whether they use it is the most consequential financial decision they will make in the next decade.
