The Tax Time Bomb in Their IRAs
Nearly $1.9 million sits in tax-deferred accounts. Every dollar will be taxed on the way out — and the IRS has a schedule.
When Robert rolled over his 401(k) after retirement, he didn't think much about it. But their financial advisor laid it out plainly: at age 73, the IRS would require them to start withdrawing a percentage of those traditional IRA balances every year — whether they needed the money or not.
With $1.9 million in tax-deferred accounts growing at even a modest rate, their RMDs could easily exceed $78,000 per year by the time they kicked in. Combined with their pensions, Social Security, and dividend income, that would push their adjusted gross income well above $250,000 — potentially triggering higher Medicare premiums (IRMAA surcharges), increased capital gains tax rates, and a larger portion of their Social Security becoming taxable.
Their advisor proposed a Roth conversion ladder: systematically converting portions of their traditional IRAs to Roth IRAs each year between now and age 73, paying the tax now at a lower rate to avoid the bigger hit later. The sweet spot was converting roughly $80,000 to $100,000 per year. It meant writing large checks to the IRS in years when they didn't technically owe much. Psychologically, that was harder than any investment decision Robert had ever made.

The Roth Conversion Window
The years between retirement and age 73 are often called the 'golden window' for Roth conversions. Income is typically lower, tax brackets are more favorable, and every dollar converted grows tax-free for the rest of your life — and your heirs' lives.
The Reality Check
Paying $19,000+ in voluntary taxes this year to potentially save $200,000 over two decades requires a level of trust in the math that doesn't come naturally.
