A retiree with $1.5 million in a 401(k) faces $280,000 in cumulative taxes over 17 years due to shrinking RMD divisors.
A 73-year-old retiree with $1.5 million in a traditional 401(k) will owe approximately $280,000 in federal taxes over 17 years due to required minimum distributions (RMDs). The IRS Uniform Lifetime Table divisor of 26.5 at age 73 mandates a $56,604 withdrawal, taxed at 20%.
The divisor shrinks annually, increasing withdrawal amounts. At 74, the divisor drops to 25.5, and by age 80, it reaches 20.2. Assuming 6% portfolio growth, cumulative RMDs could total $1.4 million by age 90, triggering significant tax liabilities.
Retirees can mitigate taxes using qualified charitable distributions (QCDs) up to $111,000 annually, reducing modified adjusted gross income (MAGI) and avoiding IRMAA surcharges or Social Security taxation.
