The Roth Conversion Strategy Affluent Couples Over 60 Are Using to Drain a $1.4 Million 401(k) Before RMDs Begin Quick Read – Retiring at 61 with no Social Security yet creates a 12-year window to convert a $1.4M 401(k) into a Roth at voluntarily chosen tax rates. – Converting…
40,000 annually keeps a couple inside the 22% bracket, draining the full balance in 6-7 years before RMDs force withdrawals at 32%-plus. – Conversions must stop before age 63, since Medicare’s two-year IRMAA lookback uses that income to set higher premiums when coverage begins at 65. – A married couple, both 61, just walked away from W-2 income with $1.4 million in a traditional 401(k). They plan to defer Social Security until 70
That decision, paired with the fact that required minimum distributions don’t begin until 73, hands them something most retirees never get: a roughly 12-year runway where their taxable income is whatever they choose to make it. Affluent couples in this exact spot are using that window to systematically drain the pre-tax 401(k) into a Roth, paying tax voluntarily at today’s brackets to avoid a forced withdrawal at tomorrow’s. The math is unusually clean, and the 2026 brackets make it cleaner than it has been in years.
The bracket-fill math on a $1.4 million balance Start with the 2026 numbers for a married couple filing jointly. The standard deduction is $32,200. The 22% bracket runs up to $100,800 of taxable income, the 24% bracket extends to $211,400, and the 32% cliff doesn’t hit until $403,550.
