Three Lesser-Known But Powerful 401(k) Features

Maximizing retirement savings often requires leveraging underutilized 401k features that extend beyond standard investment menus. Self-directed brokerage accounts provide access to individual stocks and a wider range of ETFs, yet remain significantly underused due to participant unawareness. The mega backdoor Roth strategy enables high-income earners to contribute after-tax funds and convert them into Roth assets, creating a tax-free growth vehicle, provided the employer’s plan supports such conversions and passes annual non-discrimination testing. Additionally, the rule of 55 offers a critical exception to the 10% early withdrawal penalty, allowing individuals who separate from service during or after the calendar year they turn 55 to access retirement funds penalty-free. These strategies require careful coordination with plan providers to ensure eligibility and avoid unintended tax consequences.
