If you have company stock inside a 401(k) or other employer-sponsored retirement plan, you may be sitting on one of the most valuable – and most commonly missed – tax strategies in retirement planning: net unrealized appreciation, or NUA.
Most people roll their entire 401(k) into an IRA when they retire or change jobs. That’s often the right move for most of the account. But for the employer stock portion, a blanket rollover may mean paying ordinary income tax rates on appreciation that could instead be taxed at long-term capital gains rates – potentially saving tens of thousands of dollars in a single transaction.
This guide covers exactly how the NUA strategy works, who qualifies, the triggering events required, step-by-step execution, calculation examples, employer-specific scenarios for ExxonMobil, Chevron, and Lockheed Martin employees, and how NUA compares to a full IRA rollover.
The NUA strategy involves distributing employer stock in-kind from a 401(k) or similar plan to a taxable brokerage account rather than rolling it into an IRA. You pay ordinary income tax on the original cost basis of the shares at distribution. The Net Unrealized Appreciation – the gain above that cost basis – is then taxed at long-term capital gains rates when you eventually sell, regardless of how long you hold the shares after distribution. For employees with highly appreciated company stock, this can produce dramatically lower total tax than a standard rollover.
What Is Net Unrealized Appreciation (NUA)?
Net Unrealized Appreciation is the difference between the current fair market value of employer stock held in a qualified retirement plan and the original cost basis – what the plan paid for the shares.
The term comes directly from IRS tax code. Under IRC §402(e)(4) (IRS Publication 575), when employer securities are distributed from a qualified plan as part of a lump-sum distribution, the NUA on those securities is excluded from ordinary income at the time of distribution.
Instead, it’s taxed as long-term capital gain when the shares are eventually sold – regardless of how long you hold them after the distribution.
That distinction is the entire value of the NUA strategy. If you roll company stock into an IRA, every dollar that comes out later is taxed as ordinary income – potentially at rates up to 37%. Under NUA treatment, only the cost basis is taxed as ordinary income at distribution; the appreciation is taxed at the more favorable long-term capital gains rate of 0%, 15%, or 20%.
NUA Defined: A Simple Example
You have 1,000 shares of ExxonMobil stock inside your 401(k). The plan purchased those shares over the years at an average price of $50 per share – a total cost basis of $50,000. Today, the shares are worth $150 each, for a total value of $150,000.
- Cost basis: $50,000
- Current market value: $150,000
- Net Unrealized Appreciation (NUA): $100,000
Under a standard IRA rollover, all $150,000 eventually comes out as ordinary income. Under an NUA distribution, the $50,000 cost basis is taxed as ordinary income at distribution, and the $100,000 of NUA is taxed at long-term capital gains rates when sold.
NUA Triggering Events: The Four Qualifying Circumstances
NUA treatment is only available when a “lump-sum distribution” occurs from a qualified retirement plan. The IRS defines this as distribution of the entire account balance within a single tax year, triggered by one of four qualifying NUA events:
NUA Triggering Event 1: Separation from Service
Leaving an employer – through retirement, resignation, layoff, or termination – triggers the ability to take a lump-sum distribution. This is the most common NUA triggering event.
Note that for this trigger, you must actually separate from the employer sponsoring the plan. Separating from a subsidiary while transferring to the parent company may not qualify – confirm with your plan administrator before executing.
NUA Triggering Event 2: Reaching Age 59½
Turning 59½ allows a lump-sum distribution from a qualified plan even if you’re still employed. This means you don’t have to wait until you actually retire to execute an NUA strategy – you can take the distribution while still working, provided your plan documents permit in-service distributions.
NUA Triggering Event 3: Death
The death of the plan participant triggers lump-sum distribution eligibility for beneficiaries. Beneficiaries who inherit employer stock in a qualified plan can elect NUA treatment on the distributed shares.
NUA Triggering Event 4: Disability
Becoming disabled (as defined under IRC §72(m)(7)) qualifies as a triggering event. This applies to self-employed individuals only for this specific trigger; employees qualify based on their employer’s disability determination.
The NUA Lump-Sum Distribution Requirement
All four triggers require that you distribute the entire account balance in a single tax year – not just the stock. This is a critical and often misunderstood requirement. You can’t take just the company stock as an NUA distribution and leave the rest in the plan.
The entire balance – cash, mutual funds, bonds, and employer stock – must be distributed within the same calendar year. The non-stock portion can be rolled into an IRA (which is almost always the right move for that portion). The employer stock portion is taken as an in-kind distribution to a taxable brokerage account.
How the NUA Strategy Works: Step-by-Step
Step 1: Confirm NUA Eligibility
Verify that one of the four NUA triggering events has occurred or is imminent. Check your plan documents to confirm that the plan holds employer securities that qualify. Most 401(k) plans, ESOPs (Employee Stock Ownership Plans), and profit-sharing plans qualify for NUA treatment. 403(b) plans and 457 plans typically do not.
Also confirm with your plan administrator what your cost basis is for the employer stock – the plan is required to track this. If the plan cannot provide your cost basis, the NUA calculation becomes problematic.
Step 2: Decide Which Shares to Include for NUA
If you have employer stock from multiple purchase dates and prices – common when stock was contributed over many years or through an ESOP – you may have flexibility in which shares to distribute for NUA purposes.
Generally, distributing shares with the lowest cost basis maximizes the NUA benefit – more of the total value is treated as NUA rather than ordinary income at distribution. Work with your advisor and plan administrator to understand your lot structure before executing.
Step 3: Direct the NUA Distribution
Contact your plan administrator and instruct them to distribute the employer stock in-kind (not sold first) to a taxable brokerage account you designate, roll the remaining non-stock assets into a traditional IRA, and complete both within the same calendar year.
The stock must be distributed in-kind – meaning the actual shares are transferred, not liquidated and distributed as cash. If the plan sells the stock and sends you cash, you lose the NUA treatment entirely.
Step 4: Report the NUA Distribution
Your plan administrator will issue a 1099-R showing the NUA distribution. Box 6 of the 1099-R reports the NUA amount specifically.
You’ll report the cost basis as ordinary income on your tax return for the year of distribution. That amount is not taxed until you sell the shares.
Step 5: Sell the NUA Shares When Ready
Once the shares are in your taxable brokerage account, you can hold them as long as you choose. When you sell, the NUA is taxed at long-term capital gains rates – regardless of how long you’ve held the shares since distribution.
Any additional gain above the distribution-date value is taxed at short or long-term rates depending on the holding period post-distribution.
NUA Calculation Example with Numbers
Let’s walk through a detailed calculation to illustrate the real dollar impact.
The NUA Scenario
Sarah is retiring at 62 from a large energy company. Her 401(k) contains $200,000 in mutual funds and cash, plus 2,000 shares of company stock with a cost basis of $40,000 and a current value of $280,000. Total account value: $480,000. NUA on the stock: $240,000 ($280,000 – $40,000).
Sarah is in the 24% ordinary income bracket and the 15% long-term capital gains bracket.
Option A: Full IRA Rollover (No NUA)
Sarah rolls the entire $480,000 into a traditional IRA. No immediate tax is due. But every dollar that comes out of the IRA is taxed as ordinary income. If she withdraws the $280,000 of company stock value over time, total ordinary income tax at 24%: $67,200.
Option B: NUA Strategy Distribution
Sarah rolls the $200,000 in mutual funds to an IRA and takes the company stock as an in-kind NUA distribution. Ordinary income tax on cost basis at distribution: $40,000 × 24% = $9,600. Long-term capital gains tax on NUA when sold: $240,000 × 15% = $36,000. Total NUA tax: $45,600.
NUA Tax Savings: The Difference
| Scenario | Tax on Cost Basis | Tax on Appreciation | Total Tax |
|---|---|---|---|
| Full IRA Rollover | Deferred until withdrawal | Taxed as ordinary income (24%) | $67,200 |
| NUA Strategy | $9,600 (24% at distribution) | $36,000 (15% capital gains) | $45,600 |
| NUA Tax Savings | $21,600 | ||
This $21,600 in savings assumes the same ordinary income bracket at distribution and at the time of IRA withdrawals. If Sarah’s tax bracket drops in later retirement years, the IRA rollover advantage grows. If her bracket stays the same or increases, the NUA advantage is even larger.
NUA vs. IRA Rollover: Complete Comparison
| Factor | NUA Distribution | Full IRA Rollover |
|---|---|---|
| Tax on cost basis | Ordinary income at distribution | Deferred until withdrawal |
| Tax on NUA / appreciation | Long-term capital gains (0%, 15%, 20%) | Ordinary income (10%-37%) |
| Immediate tax impact | Yes – tax owed in distribution year | No immediate tax |
| RMD requirement | No RMDs on taxable account | RMDs begin at age 73 |
| Step-up in basis at death | Yes – on post-distribution appreciation (not the NUA itself) | No step-up; IRA withdrawals taxed as ordinary income |
| 10% early withdrawal penalty | May apply to cost basis if under 59½ (not to NUA) | No penalty if rolled to IRA within 60 days |
| Best when | High NUA, high tax bracket, large gap between ordinary income and capital gains rates | Low NUA, expect lower bracket in retirement, need to defer taxes |
NUA vs. Roth Conversion: Which Wins?
Some employees with appreciated company stock consider a Roth conversion as an alternative to or complement of the NUA strategy. These are fundamentally different tools.
A Roth conversion moves pre-tax IRA or 401(k) assets to a Roth IRA, paying ordinary income tax now in exchange for tax-free growth and withdrawals later. It makes most sense when you expect to be in a higher tax bracket in the future or want to eliminate RMDs.
The NUA strategy applies specifically to employer stock and converts the appreciation from ordinary income treatment to long-term capital gains treatment. NUA doesn’t eliminate tax on the appreciation – it reduces the rate applied to it.
These strategies can work together: execute the NUA distribution on company stock, roll the remaining plan assets to an IRA, then convert portions of that IRA to Roth in low-income years to further reduce future RMD pressure. The order and timing of these moves significantly affects the outcome.

NUA Tax Rules: What the IRS Actually Requires
NUA Tax Rule: The Cost Basis Calculation
Only the employer’s cost basis at the time of each purchase creates taxable ordinary income at distribution – not the value of the shares when distributed. If your company’s ESOP purchased shares at $30 fifteen years ago and they’re worth $120 today, only $30 per share is taxed as ordinary income at distribution. The $90 of appreciation is the NUA.
NUA Tax Rule: After-Tax Contributions
If you made after-tax contributions to the plan that were used to purchase employer stock, those after-tax amounts become part of your cost basis – but they’re returned to you tax-free at distribution (since you already paid tax on them).
This can reduce the ordinary income tax owed at distribution but also reduces the NUA amount itself.
NUA Tax Rule: The 10% Early Withdrawal Penalty
If you’re under 59½ when you take the NUA distribution, the cost basis portion is subject to the 10% early withdrawal penalty unless you qualify for an exception. The most common exception for NUA purposes: separating from service at age 55 or older (the “rule of 55”).
The appreciation portion is never subject to the 10% penalty – only the cost basis taxed as ordinary income.
NUA Tax Rule: Holding Period After Distribution
The appreciation is automatically treated as long-term capital gain regardless of how long you hold the shares after distribution – even if you sell them the next day. However, any additional appreciation above the distribution-date fair market value is short-term or long-term based on your actual holding period after the distribution date.
NUA Tax Rule: Net Investment Income Tax (NIIT)
High-income taxpayers should be aware that the 3.8% Net Investment Income Tax may apply to the NUA gain upon sale. This applies to single filers with MAGI above $200,000 and joint filers above $250,000.
Factor the NIIT into your comparison with the IRA rollover scenario when modeling total tax cost.
Employer-Specific NUA Scenarios
ExxonMobil NUA: ESOP and Savings Plan Considerations
ExxonMobil employees often accumulate significant company stock through both the ExxonMobil Savings Plan and the Employee Stock Ownership Plan (ESOP). The ESOP component is particularly relevant for NUA planning because shares may have been contributed by ExxonMobil at a very low cost basis relative to today’s stock price – creating substantial NUA.
Key considerations for ExxonMobil NUA planning:
- Shares acquired through the ESOP at employer contribution prices often have a low cost basis relative to current market value, maximizing the NUA benefit
- ExxonMobil’s stock has appreciated significantly over long careers, meaning employees with 20-30 year tenures may have enormous NUA relative to cost basis
- The lump-sum distribution requirement means coordinating the timing of ExxonMobil plan distributions carefully – the entire plan balance must be distributed in the same calendar year
- ExxonMobil pension income should be factored into bracket calculations to determine whether the NUA strategy produces net tax savings given your anticipated total income in the distribution year
Chevron NUA: Employee Savings Investment Plan
Chevron’s Employee Savings Investment Plan (ESIP) allows employees to invest in Chevron stock, which has created NUA opportunities for long-tenured employees in the energy sector. For Chevron employees considering this strategy:
- Determine your cost basis by contacting Fidelity (Chevron’s plan administrator) before making any distribution decisions
- Chevron’s stock price fluctuations tied to energy markets mean timing the distribution relative to stock price matters – NUA is most valuable when the stock is highly appreciated at the time of distribution
- Chevron employees who also receive pension benefits need to model total retirement income carefully to determine whether the NUA distribution will push them into a higher bracket in the distribution year
- Phased retirement or partial separation scenarios may complicate the lump-sum distribution requirement
Lockheed Martin NUA: 401(k) and ESPP Considerations
Lockheed Martin offers both a 401(k) Savings Plan and an Employee Stock Purchase Plan (ESPP). For employees with substantial Lockheed Martin stock holdings considering this strategy:
- Lockheed Martin’s defense sector positioning has created strong stock appreciation over long employee careers, often producing significant NUA for long-tenured employees
- ESPP shares purchased at a discount create an immediate cost basis advantage – the discount is taxed as ordinary income at purchase, but subsequent appreciation qualifies as NUA upon distribution
- Government contractor retirement timelines often align with the rule of 55 exception, which can eliminate the 10% early withdrawal penalty on the NUA cost basis if separation occurs at 55 or older
- Lockheed Martin employees with both pension and 401(k) income should model the distribution year carefully, as pension income adds to ordinary income and may affect bracket calculations
When the NUA Strategy Does NOT Make Sense
The NUA strategy is not universally better than a full IRA rollover. It typically makes less sense when:
- Low appreciation relative to cost basis: If most of the stock value is cost basis rather than appreciation, the ordinary income tax hit at distribution may exceed the long-term benefit. A general guideline: NUA should be at least 2-3x the cost basis for the strategy to be clearly advantageous.
- You’ll be in a much lower bracket in retirement: If your ordinary income tax rate drops significantly after retirement, a full rollover followed by lower-rate IRA withdrawals may produce less total tax than the NUA distribution in a high-income year.
- You need the money immediately: Taking an NUA distribution accelerates the cost basis tax, which is a real cash outflow in the distribution year. If you need the funds and can’t absorb that tax bill, the timing doesn’t work.
- The stock has declined significantly: If the company stock is worth less than you paid for it, there’s no appreciation to capture. Distributing the stock may still make sense for concentration risk reduction, but through different means.
- Your estate plan benefits more from the IRA: If you plan to leave the stock to heirs, the step-up in basis at death already applies to taxable accounts – but for an IRA, there’s no step-up. This can make the IRA rollover more estate-tax efficient in some circumstances.
Frequently Asked Questions About the NUA Strategy
What are the NUA triggering events?
There are four qualifying triggering events for an NUA distribution: (1) separation from service – leaving the employer through retirement, resignation, or termination; (2) reaching age 59½, even while still employed if the plan permits in-service distributions; (3) death of the participant; and (4) disability as defined under IRC §72(m)(7). All four triggers require distributing the entire plan balance within a single calendar year to qualify as a lump-sum distribution.
Can you do NUA while still working?
Yes – if you’ve reached age 59½ and your plan allows in-service distributions, you can execute an NUA strategy without separating from your employer. Not all plans permit in-service distributions, so check your plan documents first. If your plan does allow them, reaching 59½ is a qualifying triggering event that enables a lump-sum distribution even while actively employed.
What are the disadvantages of NUA?
The primary disadvantages of the NUA strategy are: (1) you owe ordinary income tax on the cost basis in the distribution year – a real immediate tax bill; (2) if you separate under age 59½ without qualifying for the rule of 55 or another exception, the 10% penalty applies to the cost basis; (3) the NUA benefit is reduced if your ordinary income and capital gains rates are close together; (4) the lump-sum distribution requirement means distributing your entire plan balance in one year; (5) if you expect to be in a significantly lower bracket in retirement, a deferred IRA rollover may produce less total tax overall.
What is the 10% penalty for net unrealized appreciation?
The 10% early withdrawal penalty can apply to the cost basis portion of an NUA distribution if you’re under age 59½ and don’t qualify for an exception. The penalty does not apply to the NUA itself – only to the cost basis amount taxed as ordinary income at distribution. Common exceptions that eliminate the penalty for the cost basis: separating from service at age 55 or older (the “rule of 55”), disability, and a qualified domestic relations order (QDRO). The NUA portion is never subject to the 10% penalty.
Does NUA get a step-up in basis at death?
Partially. When an NUA participant dies holding shares in a taxable brokerage account, the post-distribution appreciation (any increase in value from the NUA distribution date to the date of death) receives a step-up in basis. However, the NUA itself – the appreciation that existed inside the plan at the time of distribution – does not get a step-up. Heirs who inherit these shares will still owe long-term capital gains tax on that appreciation, though not on additional appreciation that occurred after the distribution date if they hold until death.
How is NUA reported on taxes?
Your plan administrator issues a 1099-R for the year of NUA distribution. Box 6 of the 1099-R specifically identifies the NUA amount. The cost basis is reported as ordinary income on your Form 1040 for the distribution year. The appreciation itself is not taxable in the distribution year – you report it (on Schedule D) only when you sell the shares. When you sell, the NUA is treated as long-term capital gain regardless of your holding period since distribution.
What’s the difference between NUA and a Roth conversion?
An NUA distribution applies specifically to employer stock and converts the appreciation from ordinary income treatment to long-term capital gains treatment. A Roth conversion applies to any pre-tax retirement assets and converts them to tax-free growth and withdrawals by paying ordinary income tax now. NUA reduces the rate on appreciation but doesn’t eliminate it. A Roth conversion eliminates future tax entirely but taxes the full converted amount at ordinary income rates. The strategies can complement each other: execute the NUA distribution on company stock, roll remaining assets to an IRA, then make strategic Roth conversions in low-income years.
What types of plans qualify for NUA treatment?
Plans that qualify for NUA treatment include: 401(k) plans, profit-sharing plans, money purchase pension plans, and employee stock ownership plans (ESOPs). Plans that do not qualify for NUA include 403(b) plans, 457 plans, IRAs (traditional, Roth, SEP, and SIMPLE), and non-qualified deferred compensation plans. The stock must be “employer securities” – stock of the employer company or its parent or subsidiary. Stock of an unrelated company does not qualify for NUA treatment even if held inside a qualified plan.
The NUA Decision Requires Precision – Get It Right the First Time
An NUA distribution is irreversible. Once you’ve taken the lump-sum distribution, you can’t roll the stock back into the plan. Bogart Wealth specializes in NUA strategy for employees of ExxonMobil, Chevron, Lockheed Martin, and other major employers – running the numbers, modeling the comparison, and coordinating the execution to capture the full benefit without triggering avoidable penalties or tax exposure.
