Why Retirees Overpay on Company Stock — and How to Fix It
TREE NEWS reports: A widely followed piece of retirement advice is quietly costing some investors six figures: the instinct to roll over an entire 401(k) — including deeply appreciated employer stock — into an IRA. For a specific slice of retirement savers, that single move can trigger ordinary income tax on gains that could otherwise be taxed at lower long-term capital gains rates.
The issue centers on a little-known provision called Net Unrealized Appreciation, or NUA. When employees hold company stock inside their 401(k), the cost basis is typically what the employer paid for it. If that stock has since multiplied in value, the embedded gain is enormous. Rolling it into an IRA preserves tax deferral but converts every future dollar of withdrawal into ordinary income. Instead, retirees may be able to distribute the shares in-kind, pay ordinary income tax only on the original basis, and then pay long-term capital gains rates on the appreciation when they eventually sell.
How Big Is the Gap?
Consider a retiree with $200,000 of employer stock in a 401(k) that originally cost $20,000. Rolling to an IRA means the full $200,000 eventually gets taxed as ordinary income — potentially at a 24% to 37% federal rate. Using NUA, the retiree pays ordinary income tax on just $20,000, then long-term capital gains rates (0%, 15%, or 20%) on the remaining $180,000. At a 32% ordinary bracket versus a 15% capital gains rate, the difference on the gain alone can exceed $30,000 — and for larger positions, six figures.
The catch: the rules are strict. The entire 401(k) balance must be distributed in a single tax year, which can push the retiree into a higher bracket and inflate Medicare IRMAA surcharges. The stock must be held for the required period, and only employer securities qualify. There is no partial NUA election.
Market Implications
This is a personal-finance story, but it has second-order effects worth watching:
- Brokerage and wealth-management flows: Advisors who master NUA planning can capture and retain high-net-worth rollover assets. Firms with strong retirement-planning practices — and the custodians that hold distributed shares — stand to benefit.
- Equity supply dynamics: Concentrated employer-stock positions that are distributed in-kind rather than liquidated inside an IRA can stay off the market longer, marginally tightening float in some large-cap names with heavy employee ownership.
- Tax-sensitive selling: Retirees who elect NUA may time sales around capital gains thresholds, creating pockets of supply around year-end and after long holding periods.
- Fixed income and cash: The lump-sum distribution requirement can force retirees to hold cash or short-duration bonds to cover the tax bill, briefly boosting demand for money-market funds and Treasuries.
What Investors Should Do
NUA is not right for everyone. It makes the most sense when the stock’s cost basis is very low relative to current value, when the retiree can absorb a large one-year income spike, and when they are comfortable holding a concentrated position — a risky proposition for anyone near or in retirement. The math should be run before any rollover paperwork is signed, ideally with a tax professional modeling both paths side by side.
The broader lesson is that default advice — “always roll your 401(k) into an IRA” — is not always optimal. For investors with appreciated employer stock, the difference between a reflexive rollover and a deliberate NUA election can be worth more than a decade of portfolio returns.
Key Takeaways
- Rolling appreciated employer stock into an IRA can convert capital gains into ordinary income.
- Net Unrealized Appreciation allows lower capital gains treatment on the appreciation.
- The election requires a full lump-sum distribution in one tax year, with bracket and Medicare implications.
- Run the numbers with a tax professional before signing rollover forms.
