Year-Old Tech Exec Holds $1.6 Million in One Stock. The Wrong Move Could Cost $400,000.

On her final day, a 64-year-old software executive exits with $1.6 million in a single employer stock position, bought at a $240,000 cost basis. The vested stake holds roughly $1.36 million in unrealized long-term gains, creating a hefty tax decision for the retiree. The challenge is how to unwind the position without triggering a prohibitive tax bill that could reach well over $400,000, depending on the strategy chosen. This dynamic is common among late-career executives in tech, finance, and pharma, where concentrated stock forms a sizable balance-sheet line item. This choice often determines long-term retirement security.

Analysts typically compare three tax paths. Path A would liquidate the entire stake in 2026, pushing most gains into the 20% federal LTCG bracket, triggering the 3.8% NIIT on amounts above thresholds and adding state taxes. Path B spreads sales over four retirement years, keeping gains in the 15% bracket while remaining under NIIT limits, often saving six figures versus a lump-sum sale. Path C mentions a Net Unrealized Appreciation election, a strategy used to favor stock-based gains. The decision hinges on future stock performance and evolving tax rules, with macro factors also relevant. Overall, these options reflect a balance between current tax law and expectations for future rate changes.
