Net Unrealized Appreciation (NUA): What to Know About Company Stock in Your 401(k)
If you hold company stock in your 401(k), there is a tax rule you may want to understand before you roll the account into an IRA. Net unrealized appreciation, often called NUA, can change how part of that stock is taxed. For employees and executives who bought company shares over many years at a low cost, the difference may be significant.
It is also a decision that cannot be undone once you roll the shares over, and it involves concentration risk. This guide explains how NUA works, when an NUA strategy may be worth evaluating, and why it belongs in both your investment plan and your tax plan.
Start Here: A Complimentary Wealth and Tax Review
An NUA decision usually happens at a major transition, such as retirement or leaving an employer. Compound offers a complimentary, no-obligation wealth and tax review that may include:
Your plan statements: company stock holdings and their cost basis
Your tax picture: current and projected income over the next several years
Concentration risk: how much of your net worth is tied to one company
Retirement income: how distributions fit with other sources
Estate and charitable goals: how the shares may fit into legacy plans

What Is Net Unrealized Appreciation?
Net unrealized appreciation is the difference between what your employer stock is worth today and its cost basis inside the plan, meaning what was paid for it.
Normally, everything that comes out of a traditional 401(k) is taxed as ordinary income. Under the NUA rules, if you take employer stock out of the plan as actual shares, rather than rolling it into an IRA, the tax treatment splits into parts:
The cost basis is generally taxed as ordinary income in the year of the distribution.
The NUA portion is not taxed until you sell the shares, and when you do, it is generally taxed at long-term capital gains rates, regardless of how long you held the shares after distribution.
Any growth after distribution is taxed as a short-term or long-term gain depending on how long you hold the shares after they leave the plan.
The rest of the account, such as mutual funds, can usually be rolled into an IRA to continue tax deferral.
Requirements for an NUA Strategy
The rules are specific, and missing one can disqualify the treatment. In general:
A qualifying event. Typical triggers include separation from service, reaching the age specified in the rules, death, or, for self-employed individuals, disability.
A lump-sum distribution. The entire vested balance of the plan generally must be distributed within a single tax year.
Shares distributed in kind. The employer stock must come out as shares to a taxable brokerage account, not sold inside the plan first.
If you are younger than the qualifying age when you take the distribution, an additional penalty may apply to the taxable portion. A tax professional should review your plan documents and timeline before any distribution is processed.
When May NUA Make Sense?
An NUA strategy is often worth evaluating when:
The cost basis is low relative to current value. The bigger the gap, the more of the value may qualify for capital gains treatment.
You can manage the upfront tax. Ordinary income tax is due on the basis in the year of distribution.
Your income may be lower in the distribution year. A year after retirement, before other income begins, may reduce the cost of recognizing the basis.
You want flexibility. Shares held in a taxable account are not subject to required minimum distributions.
It may make less sense when the basis is high, when the stock has little appreciation, or when you would rather diversify immediately and the tax difference is small. Some people apply NUA to only a portion of their shares and roll the rest. Comparing scenarios is part of good tax planning and preparation.
Company Stock in Your 401(k): The Concentration Question
The tax rule is only one part of the decision. Holding a large amount of company stock in your 401(k) can leave your savings, and often your paycheck, tied to the same company. If that company struggles, both can suffer at once.
Wealth management looks at NUA through that lens:
How much concentration is acceptable? A plan may sell shares gradually over several years to manage both taxes and risk.
What role do the shares play? They may fund near-term spending, support charitable gifts, or be held for the long term.
How does the rest of the portfolio adjust? Your IRA and other accounts can be positioned around the concentrated holding. See investment management for high net worth individuals.
Gifting appreciated shares to a donor-advised fund or charity may also be worth discussing. One more point: NUA shares generally do not receive a step-up in basis for the NUA portion at death, which matters for estate planning. Coordinate with your estate attorney if the shares are part of your legacy plan.

Coordinating NUA With Your Retirement Plan
NUA rarely stands alone. The distribution year can also affect Roth conversion opportunities, the order of retirement withdrawals, and Social Security timing. A decision that looks attractive in isolation may look different once those pieces are modeled together. Read more about retirement planning in Wisconsin and evaluating a Roth conversion strategy.

Frequently Asked Questions
What is net unrealized appreciation?
Net unrealized appreciation is the increase in value of employer stock held in a retirement plan above its cost basis. Under specific rules, that gain may be taxed at long-term capital gains rates when the shares are sold.
How does an NUA strategy work?
Employer shares are distributed in kind to a taxable account as part of a qualifying lump-sum distribution. The cost basis is taxed as ordinary income at distribution, and the NUA is taxed as a capital gain when sold.
Should I roll company stock in my 401(k) into an IRA?
It depends on your cost basis, tax picture, and concentration risk. Once shares are rolled into an IRA, NUA treatment is generally no longer available, so it is worth reviewing before acting.
Can I use NUA for only part of my company stock?
Often yes. Some people distribute a portion of shares in kind and roll the rest to an IRA, depending on plan rules and goals.
What are the risks of an NUA strategy?
The main risks are holding too much of one stock, paying ordinary income tax upfront, and failing a technical requirement that disqualifies the treatment.
