Overview
Roth Conversion Strategy in 2026
A Roth conversion moves money from a pre-tax traditional IRA or 401(k) to a Roth account, triggering taxes now in exchange for tax-free growth and withdrawals forever. The fundamental question: will your tax rate be higher now or in retirement?
The RMD Problem
Required Minimum Distributions (RMDs) begin at age 73 under SECURE 2.0. If you have $1,200,000 in traditional IRAs at 73, your RMD is roughly $43,000 in Year 1 — whether you need the money or not. At $2,000,000, it’s $72,000. These RMDs layer on top of Social Security, potentially pushing you into higher brackets and triggering Medicare IRMAA surcharges ($600–$5,000+/year in extra premium). Strategic conversions in your 60s and early 70s can reduce the RMD bomb before it detonates.
The Break-Even Calculation
Break-even = years for tax-free Roth growth to offset upfront conversion taxes. On a $50,000 conversion at 22% ($11,000 in taxes paid today), at 7% annual return: the Roth advantage grows approximately $3,500/year vs a taxable account. Break-even is roughly 3 years. On a 20–30 year retirement, the Roth wins substantially.
