A $2.1 Million Portfolio, Two Withdrawal Plans: One Triggers IRMAA and RMD Taxes, One Never Does

A $2.1 million investment portfolio, comprising $1.05 million in a taxable brokerage account and $1.05 million in a traditional IRA, can generate a six-figure income. However, the placement of these holdings and the timing of withdrawals significantly impact the potential for Medicare surcharges and required minimum distributions (RMDs).

Only Roth conversions, qualified charitable distributions, or never owning a traditional IRA can truly reduce the RMD burden. Medicare surcharges attached to premiums occur two years after the income that triggers them, which increases the monthly cost for joint filers from $203 to $284 when the Modified Adjusted Gross Income (MAGI) exceeds $218,000.

Failing to manage these withdrawals and holdings can lead to higher taxes and Medicare surcharges during retirement years.
