Retirees Need Coordinated Withdrawal Plans to Protect 22% Tax-Bracket Income

$300,000 in retirement savings can translate into very different spendable income depending on account type, with a $100,000 traditional IRA worth about $78,000 after federal tax in a 22% bracket.
Withdrawal order drives that gap: rigidly spending taxable assets first and tax-deferred money later can waste low tax brackets, while blending IRA, taxable and Roth withdrawals can smooth lifetime taxes.
RMDs starting at 73 or 75 can later stack on top of Social Security and pensions, raising both tax bills and Medicare IRMAA surcharges that kick in when income crosses a threshold by even $1.
Social Security claiming is part of the same strategy, since up to 85% of benefits can be taxable and delaying benefits can cut future RMDs while increasing checks by 8% a year until age 70.
The broader lesson is to judge withdrawals across decades—not a single tax year—so retirees also account for surviving-spouse brackets and heirs who often must empty inherited IRAs within 10 years.
