Strategic Roth conversions during the seven-year window before RMDs start allow retirees to lock in lower tax rates and avoid future Medicare premium hikes, potentially saving $185,000.
The 10-year Treasury yield at 4.77% is cited as the risk-free opportunity cost for Roth conversion tax savings.
Retirees aged 63 to 69 can significantly reduce lifetime tax burdens by converting traditional 401(k) assets to Roth accounts before RMDs begin. By staying within the 12% tax bracket and avoiding Medicare IRMAA surcharges, a couple can save approximately $185,000 in federal taxes compared to waiting until their 70s.
This period, before Required Minimum Distributions (RMDs) and Social Security benefits begin, allows retirees to control their taxable income and convert assets at lower marginal tax rates.
