If you’ve spent years building a meaningful position in company stock inside your 401(k), retirement or a job change can create an important tax planning decision. For some individuals, rolling a 401(k) into an IRA may be a reasonable default. But when employer stock is involved, it might be worth pausing before making that move. If the account includes highly appreciated company stock, rolling everything into an IRA may eliminate a tax treatment that could have been more favorable.
By using a tax strategy known as Net Unrealized Appreciation (NUA), you may be able to have the growth portion of your company stock taxed at long-term capital gains rates rather than ordinary income tax rates.
Frequently Asked Questions About NUA Strategy
1. What is Net Unrealized Appreciation (NUA), and how it can save on taxes?
NUA is the difference between the original value purchased or contributed (cost basis) of company stock held inside your 401(k) and the stock’s current market value.
Normally, when you take money out of a traditional 401(k), distributions are taxed as ordinary income, with top federal rates currently reaching 37% in 2026.
With an NUA strategy in place, the employer stock is treated differently from the rest of the 401(k) assets during a qualifying distribution. The non-company stock assets are moved into a rollover IRA to maintain tax deferral, while the highly appreciated company stock is transferred in-kind into a taxable brokerage account. When this is done correctly:
- You pay ordinary income tax only on the stock’s cost basis.
- The appreciation, or NUA, is not taxed as ordinary income at distribution. When the shares are eventually sold, the NUA portion is taxed at favorable capital gains rates.
Depending on the size of the appreciation and the investor’s tax bracket, that difference can create meaningful tax savings.
2. What are the IRS rules required to qualify for an NUA distribution in 2026?
NUA treatment is rules-based, and execution matters. A mistake in sequencing or distribution method can cause the NUA opportunity to be lost. To qualify, three requirements are especially important:
- A triggering event: Common triggering events include separation from service, reaching age 59½, death, or disability.
- The lump-sum requirement: The entire balance of the plan must generally be distributed within one calendar year, leaving the account balance at zero by year-end.
- An in-kind transfer: The company stock must be distributed as shares, not sold inside the plan and distributed as cash.
Important sequencing note: If employer stock is rolled into an IRA first, NUA treatment is no longer available for those shares. This is why the NUA analysis must happen before the rollover, not after.
3. When might an NUA strategy make sense for a corporate retiree?
An NUA strategy is not a universal fix. It is a tax tradeoff that should be modeled carefully. It is generally most useful when company stock has a low cost basis and meaningful appreciation.
To illustrate, consider the following simplified hypothetical example. If you hold $500,000 of employer stock with a $50,000 cost basis, the $50,000 basis would generally be taxed as ordinary income at distribution. The remaining $450,000 of appreciation may qualify for long-term capital gains treatment when the shares are sold.
NUA may also be worth evaluating during the “income gap years” between retirement and the start of Social Security or required minimum distributions (RMDs). If taxable income is temporarily lower during those years, paying ordinary income tax on the cost basis may be less expensive than it would have been during peak earning years.
The decision should also account for state taxes, Medicare premium thresholds, cash available to pay the tax, and how quickly the investor plans to diversify out of the stock.
What are some potential risks or downsides of electing NUA to consider?
The primary risks of an NUA strategy include tax acceleration at distribution and over-concentration in employer stock.
When the stock is distributed to a taxable brokerage account, the cost basis is taxed as ordinary income in that year. Ideally, the tax should be paid with outside cash, so the strategy does not create additional liquidity pressure or force an unfavorable sale.
There is also concentration risk. If a meaningful portion of retirement assets remains tied to one company’s stock, the portfolio may be exposed to risks that a diversified allocation could help reduce. The NUA decision should be paired with a plan for when and how to sell shares, manage capital gains, and diversify the portfolio over time.

Putting It All Together
For executives and long-time employees with significant company stock inside a 401(k), Net Unrealized Appreciation can represent a valuable tax planning opportunity. However, the potential benefits depend on several factors, including the stock’s cost basis, your current and future tax brackets, diversification goals, and overall retirement income strategy.
If you’re approaching retirement, changing employers, or considering a 401(k) rollover, now may be a good time to evaluate whether an NUA strategy deserves a closer look. Since the opportunity can be lost once certain rollover decisions are made, proactive planning is critical.
