Concentrated Stock Position Threatens Retirement Security for Couple Facing Large Tax Bill

An Indianapolis couple approaching retirement holds 71% of their $2.4 million portfolio in a single stock position, creating both concentration risk and a substantial $290,000 potential tax liability if liquidated. Rather than focusing primarily on the tax burden, financial advisors suggest a staged sale strategy over two to three years that aligns with lower-income periods before Social Security begins, which could reduce the effective tax rate. A detailed examination of individual share cost basis often reveals that the actual tax obligation is considerably lower than initial estimates, since shares with higher cost basis can be sold first.

The couple's situation exemplifies a widespread challenge for long-tenured employees whose compensation packages included stock incentives over decades. Rather than viewing the tax obligation as a permanent barrier to diversification, financial professionals recommend examining the actual cost basis of individual share lots, which frequently reveals substantially lower tax exposure than initial estimates. This detailed accounting matters because shares acquired at different times carry different cost basis levels, allowing strategic sales that prioritize higher-basis shares first.

A multiyear liquidation approach offers particular advantages during early retirement years when income remains temporarily depressed, before Social Security activations increase taxable earnings. This timing strategy can meaningfully shift gains into lower federal tax brackets while also reducing exposure to concentration risk immediately rather than delaying portfolio rebalancing indefinitely.
