Net Unrealized Appreciation (NUA)
Transfer 401(k) company stock with deferred capital gains taxes and maximize long-term wealth
What is Net Unrealized Appreciation?
Imagine leaving your employer with a 401(k) containing $750,000 in company stock. That stock cost $250,000 when you acquired it, but it's now worth $750,000. Normally, you'd pay ordinary income tax on the entire amount if you rolled it to an IRA. But there's a strategy that could save you over $85,000 in taxes: Net Unrealized Appreciation, or NUA.
Net Unrealized Appreciation is the difference between the cost basis (what you paid) and the current value of company stock held in a qualified retirement plan. When executed properly, NUA allows you to transfer appreciated company stock from your 401(k) to a taxable brokerage account, paying ordinary income tax only on the cost basis, while deferring the capital gains tax on the appreciation until you sell the stock—and potentially paying at a lower long-term capital gains rate.
Bottom Line: NUA lets you immediately separate the tax treatment of your company stock's original cost from its appreciation, potentially saving thousands in taxes by converting ordinary income tax liability into long-term capital gains.
Quick Facts About NUA
- Only available after separation from service (retirement, resignation, termination, layoff)
- Distribution must be in-kind of actual company stock shares, not cash
- You pay ordinary income tax on the cost basis immediately
- The appreciation (NUA) is taxed as long-term capital gains when you eventually sell
- Long-term capital gains rates (0%, 15%, or 20%) are typically lower than ordinary income rates (up to 37%)
- You must hold the stock for at least one year to qualify for long-term capital gains treatment
- Other 401(k) assets must be distributed in the same calendar year as a lump sum
Understanding NUA in Detail
The concept of Net Unrealized Appreciation originated from IRC Section 402(e)(4)(J) and Treasury Regulation 1.402(e)-2, designed to give employees who receive company stock in their retirement plans a more favorable tax treatment than a standard rollover.
How NUA Works: The Mechanics
When you participate in a 401(k) or similar qualified retirement plan that holds company stock, the IRS allows you a special election when you separate from service. Instead of rolling the entire balance to an IRA (treating all future withdrawals as ordinary income), you can elect to take a distribution of the company stock "in-kind"—meaning actual shares of stock, not cash.
The tax treatment is split into two parts:
- Cost Basis (Ordinary Income Tax): The amount the stock cost when acquired in the plan. This is subject to ordinary income tax in the year of distribution.
- Net Unrealized Appreciation (Capital Gains Tax): The gain from the cost basis to the current fair market value. If you hold the stock for more than one year after distribution, this is taxed as long-term capital gains (potentially at 0%, 15%, or 20%).
Historical Context and Legal Framework
NUA has been part of the Internal Revenue Code since 1978, created to encourage employee stock ownership plans (ESOPs) and other stock-based retirement vehicles. The provision reflects a policy preference for encouraging equity participation while allowing favorable tax treatment for wealth accumulation.
The mechanism is governed by IRC Section 402(e)(4)(J) for qualified lump-sum distributions from qualified plans. For ESOP participants, special rules under IRC Section 409(h) may apply. The Treasury has clarified these rules extensively in regulations and private letter rulings, establishing clear requirements for proper execution.
Who Benefits Most from NUA?
Persona 1: The Long-Tenured Executive (Age 50-65)
Profile: Executive earning $350,000-$500,000 annually, been at the company for 20+ years, accumulated $1.2 million in company stock (original cost: $400,000) through stock purchase plans and options exercises.
Income Level & Tax Bracket: 37% federal ordinary income tax bracket, plus state income tax (likely 5-10%), effective marginal rate around 42-47%.
Why NUA Benefits This Person: With $800,000 in unrealized appreciation, the executive faces a critical choice at retirement. Rolling all stock to an IRA and later drawing funds would result in all withdrawals taxed at 37%. With NUA, the $400,000 cost basis is taxed at 37% immediately ($148,000), but the $800,000 appreciation defers to long-term capital gains rates (likely 20% federal = $160,000 eventual tax). Net savings: approximately $80,000. Even better, if this executive delays selling until retirement, they may fall into a lower tax bracket.
Persona 2: The Mid-Career Professional with Stock Options (Age 40-50)
Profile: Director or senior manager earning $200,000-$300,000, employed for 10-15 years, holds $600,000 in company stock (cost basis: $150,000) from RSU vesting and stock awards.
Income Level & Tax Bracket: 32% federal ordinary income tax bracket, plus state and FICA taxes, effective rate around 37-40%.
Why NUA Benefits This Person: This professional hasn't reached peak retirement years but is diversifying away from the current employer. NUA allows distributing $600,000 worth of stock, paying ordinary income tax on just $150,000 (approximately $48,000 in taxes). The $450,000 appreciation becomes subject to future long-term capital gains tax only when sold. If they hold one year and then gradually sell for tax loss harvesting or diversification, they control the timing of capital gains recognition.
Persona 3: The Business Owner/Founder (Age 55+)
Profile: Founder or majority shareholder with $3-5 million in company stock in a 401(k), purchased at very low cost ($200,000-$400,000) during startup phase, now selling the company or preparing for succession.
Income Level & Tax Bracket: Highest tax bracket 37%, but likely one-time large gain event, potentially affecting Medicare premiums and surtax liability.
Why NUA Benefits This Person: In the context of a company sale, NUA becomes critical. Instead of a single massive gain that triggers net investment income tax, surtaxes, and premium increases, the founder can distribute appreciated stock in-kind, paying ordinary income tax on cost basis only, then selling after distribution at long-term capital gains rates. For a $5 million position with $4.8 million in appreciation, this could defer and reduce taxes by $300,000-$500,000.
Persona 4: The Concentrated ESOP Employee (Age 45-60)
Profile: Employee in an ESOP or employee stock ownership plan with significant company stock concentration (40-60% of net worth), $2 million in stock value, cost basis $400,000, at or near exit event.
Income Level & Tax Bracket: Variable income, often middle to upper-middle class, 24-32% federal tax bracket.
Why NUA Benefits This Person: ESOP employees face unique constraints and opportunities. NUA is particularly valuable because it allows unlocking the appreciation while deferring capital gains treatment. For a $2 million position, the difference between ordinary income (32% = $576,000) and long-term capital gains (20% = $320,000) is $256,000 in tax savings. Additionally, ESOP participants may qualify for Section 1042 rollover benefits in conjunction with NUA.
Persona 5: The Recently Departed Employee with Large Vesting (Age 35-45)
Profile: Mid-level manager who received RSU grants, recently changed jobs or laid off, 401(k) contains $400,000 in former employer stock (cost basis: $100,000), now restricted from repurchasing company stock due to employment agreement.
Income Level & Tax Bracket: Current income $120,000-$180,000, 22-24% federal tax bracket, but historical rate may have been higher when stock was awarded.
Why NUA Benefits This Person: A key advantage of NUA is the ability to diversify out of concentrated positions tax-efficiently. Rather than rolling all stock to an IRA (locking in ordinary income treatment), the employee distributes $400,000 in stock, pays ordinary income tax on $100,000 cost ($22,000), and holds the shares. Over the following years, as this person stabilizes income at new employer, they can sell shares at favorable capital gains rates. This also solves the concentration problem without triggering a massive taxable event.
Step-by-Step Implementation Guide
Step 1: Determine Eligibility (Weeks 1-2)
What You Need to Do: Verify that you meet the criteria for an NUA distribution.
Qualifying Events:
- Separation from service (quit, fired, laid off, or retired)
- Age 55 or older (for in-service distributions from specific plans)
- Disability
- Death (beneficiaries can use NUA)
Documents Needed: Separation notice or termination letter, plan documents, statement of account value and cost basis
Common Pitfall: Some employees mistakenly believe NUA is available while still employed. It's not (except for specific age 55+ in-service rules). Don't initiate a distribution until you've formally separated from service.
Pro Tip: Request your cost basis breakdown from your plan administrator immediately upon separation. This document is critical and sometimes difficult to obtain retroactively.
Step 2: Gather Documentation on Cost Basis (Weeks 1-3)
What You Need to Do: Obtain a detailed cost basis statement from your 401(k) plan administrator showing the original purchase price of all company stock shares.
Documents Needed:
- Form 1099-R historical records
- Plan statements showing cost basis for each lot of stock
- Email confirmation from plan administrator listing cost basis
- Historical option exercise statements if applicable
Timeline: Plan administrators typically respond within 10-15 business days. Request this before doing anything else.
Common Pitfall: Not getting this in writing. Verbal assurances from a plan administrator may change when the actual distribution occurs. Insist on written documentation.
Pro Tip: Create a spreadsheet with cost basis by share lot and acquisition date. This becomes your reference during tax reporting and if you need to defend your position to the IRS.
Step 3: Consult with Tax Professional (Weeks 2-4)
What You Need to Do: Meet with a CPA, tax attorney, or financial advisor experienced in NUA distributions to determine if the strategy makes sense for your specific situation.
Key Questions for Your Advisor:
- What is the size of my NUA and how much ordinary income tax will I owe in the distribution year?
- What is my long-term capital gains rate likely to be, now and in the future?
- Should I hold the stock or diversify immediately?
- Are there any special rules for my situation (ESOP, Section 1042, NIIT, IRMAA)?
- What other 401(k) assets do I have and must they be distributed?
Documents Needed: 401(k) statement showing all holdings, cost basis, current values; your federal tax return; other income sources
Typical Cost: $2,000-$5,000 for a comprehensive consultation and tax plan
Common Pitfall: Using a generic financial advisor unfamiliar with NUA. This is a specialized strategy. Seek out someone with specific NUA experience.
Step 4: Instruct Plan Administrator to Distribute In-Kind (Weeks 3-5)
What You Need to Do: Submit a written election to your plan administrator requesting in-kind distribution of company stock and lump-sum cash distribution of all other assets.
Key Elements of Your Election:
- Explicitly state this is a "lump-sum distribution" and you elect NUA treatment under IRC Section 402(e)(4)(J)
- Specify that you want company stock distributed in-kind (actual shares, not cash)
- All other plan assets must be distributed as a lump sum in the same calendar year
- Request specific shares/lots if your plan allows (for potential tax loss harvesting later)
- Specify transfer method: direct to brokerage or physical certificate
Documents to Prepare:
- Written distribution election form (plan administrator provides)
- Completed W-4P if applicable for withholding elections
- Brokerage account information where you want stock transferred
- Copy of signed election and plan documents for your records
Timeline: Plan administrators typically process distributions within 10-30 days of receiving election.
Common Pitfall: Failing to specify in-kind distribution. If you don't explicitly request it, the plan may liquidate stock and send cash instead, eliminating the NUA benefit.
Pro Tip: Keep a copy of everything you send to the plan administrator. If there's ever a dispute about cost basis or distribution type, this documentation protects you.
Step 5: Open Taxable Brokerage Account (Weeks 3-5)
What You Need to Do: If you don't already have one, open a taxable brokerage account to receive the in-kind stock distribution.
Account Requirements:
- Individual brokerage account (or joint if married)
- Ability to receive in-kind transfers (most major brokers support this)
- No account type restrictions (IRAs won't work—this defeats NUA)
- Ability to track cost basis and sell with specific lot identification
Recommended Brokers: Fidelity, Schwab, Interactive Brokers, E-Trade (all support in-kind transfers and detailed cost basis tracking)
Documents to Prepare:
- Government ID and proof of address for account opening
- Tax ID / SSN
- Plan administrator account and routing information for transfer
Timeline: Account opening typically takes 1-3 business days; transfer setup another 2-5 days.
Pro Tip: Ensure your broker supports cost basis tracking by specific lot. This is essential for potential tax loss harvesting and for accurate long-term capital gains reporting later.
Step 6: Receive and Verify Distribution (Weeks 5-8)
What You Need to Do: Confirm that shares were transferred in-kind and reconcile the distribution with plan statements.
Verification Checklist:
- Confirm number of shares received equals plan statement
- Verify share price on transfer date matches fair market value used for cost basis
- Check that all other plan assets were distributed (cash or rolled to IRA)
- Ensure brokerage account reflects correct cost basis per share
- Save all confirmations and statements
Documents Received:
- Plan administrator confirmation of distribution
- Brokerage statement showing transferred shares
- Form 1099-R from plan (due by January 31)
- Cost basis statement from plan (usually in separate communication)
Common Pitfall: Not verifying cost basis accuracy. If the plan administrator makes an error on cost basis, this will cascade to your tax forms. Check immediately and request corrections if needed.
Step 7: Coordinate with Tax Preparation (Months 10-12)
What You Need to Do: Work with your tax professional to properly report the distribution on your tax return.
Tax Forms Involved:
- Form 1099-R: Issued by plan, reports total distribution and cost basis amount
- Form 4972: Election to use special 10-year averaging (available for pre-1974 distributions only; check with advisor)
- Schedule D: Reports long-term capital gains from eventual stock sales
- Form 8949: Sales of capital assets detail
Tax Treatment Summary:
- Cost basis amount = ordinary income in year of distribution
- NUA amount = deferred until you sell the stock
- When you sell, you'll report long-term or short-term capital gain depending on holding period
Common Pitfall: Not properly reporting Form 4972 if it applies to your situation. This election can save significant taxes but requires specific tax return coding.
Pro Tip: Hold the stock for at least 13 months before selling any shares. This ensures long-term capital gains treatment on the appreciation. If you sell within 12 months, the NUA portion is still taxed as long-term capital gains, but it's easier to explain and defend.
Real Numbers & Tax Calculations
Example 1: The Concentrated Equity Executive
Scenario: Age 58, separating from tech company, $800,000 total in 401(k) - $700,000 in company stock, $100,000 in bonds.
- Company stock cost basis: $200,000
- Company stock current value: $700,000
- Net Unrealized Appreciation: $500,000
- Other assets: $100,000
Scenario A: Traditional IRA Rollover (No NUA)
| Item | Amount |
|---|---|
| Total rolled to IRA | $800,000 |
| Year 1 tax (at 35% ordinary rate) | $0 |
| Year 5 withdrawal of $350,000 (at age 63) | $122,500 tax (35% ordinary rate) |
| Year 10 withdrawal of remaining $450,000 | $157,500 tax (35% ordinary rate) |
| Total taxes over 10 years | $280,000 |
Scenario B: NUA Strategy
| Item | Amount |
|---|---|
| Cost basis taxed in Year 1 (35% ordinary rate) | $70,000 |
| Other assets rolled to IRA | $100,000 |
| Stock held in taxable account | $700,000 |
| Year 5: Sell $350,000 of stock (long-term capital gain) | Capital gain = $250,000 (appreciation) + cost basis $100,000 sold |
| Tax on $250,000 long-term capital gain (20% rate) | $50,000 |
| Year 10: Sell remaining $350,000 (long-term capital gain) | Capital gain = $250,000 (appreciation) + cost basis $100,000 sold |
| Tax on $250,000 long-term capital gain (20% rate) | $50,000 |
| Total taxes over 10 years | $170,000 |
Tax Savings: $110,000 (39% reduction)
This example shows the power of NUA when you have significant appreciation and can control the timing of sales.
Example 2: The ESOP Participant with Leverage
Scenario: Age 52, ESOP participant with $2,000,000 in company stock, cost basis $500,000, contemplating company sale.
Scenario A: Direct Liquidation in ESOP
- Company stock value: $2,000,000
- Cost basis: $500,000
- Gain on sale: $1,500,000
- Capital gains tax (20%): $300,000
- Net after-tax proceeds: $1,700,000
Scenario B: NUA + Section 1042 Rollover Strategy
- NUA distribution: $2,000,000 in stock
- Ordinary income tax on cost basis (37%): $185,000
- Stock held in taxable account post-distribution
- Use Section 1042 election: Reinvest proceeds into QSBS (qualified small business stock) or other qualifying investments
- Defer capital gains tax indefinitely while Section 1042 securities are held
- Net result: Pay ordinary income tax immediately, defer capital gains tax significantly
Benefit: Up to $300,000 in deferred capital gains tax, plus potential basis step-up at death
Example 3: The Recent Grad with Startup Stock
Scenario: Age 35, separated from tech startup, $500,000 in company stock in 401(k), cost basis $50,000, current income $100,000 at new job.
Year 1 Taxes:
- NUA distribution creates $50,000 ordinary income (24% bracket = $12,000)
- Effective tax rate on total $500,000 distribution: $12,000/$500,000 = 2.4%
- Compare to traditional rollover: $500,000 distributed later at ordinary rates (24%+) = $120,000
- Immediate tax savings just from deferent: $108,000
Future Flexibility:
- Hold stock 13+ months, then sell at long-term capital gains (15% federal)
- Tax on $450,000 appreciation: $67,500 (vs. $108,000 under ordinary rates)
- Total taxes: $12,000 + $67,500 = $79,500
- Traditional rollover would be: $120,000 + taxes on gains = $120,000+
- Lifetime savings: $40,000+
Advanced Strategies for NUA Optimization
Strategy 1: Tax Loss Harvesting with NUA Stock
How It Works: After receiving NUA stock in your taxable account, you can strategically sell shares at a loss to offset capital gains elsewhere, then repurchase or maintain long equity exposure through similar securities.
Example: You receive $700,000 in company stock. Over the next 12 months, the stock rises to $850,000, then drops to $720,000. You sell $100,000 worth at an $80,000 loss. This loss can offset other capital gains, and you can immediately repurchase similar but not-identical technology sector ETFs without violating wash-sale rules.
Tax Savings: $80,000 loss at 20% capital gains rate = $16,000 in deferred taxes. Effective cost of diversification strategy: much lower.
Best For: Investors with concentrated positions willing to gradually diversify and who have other capital gains to offset.
Strategy 2: Timing NUA Distribution Around Income Events
How It Works: Delay your NUA distribution to a year with lower ordinary income, maximizing the differential between ordinary income and capital gains rates.
Scenario: You separate from employment mid-year with $400,000 in cost basis company stock. If you take the distribution in December, you'll have income from your severance package too. Instead, elect the distribution for January of the following year when you have no severance income, potentially dropping from 32% bracket to 22% bracket.
Tax Savings: $400,000 × (32% - 22%) = $40,000 in reduced ordinary income tax.
Best For: Employees with severance packages, bonuses, or other lumpy income who can time separation strategically.
Caveat: You must separate from service before the distribution. You can't delay indefinitely—plan administrator will eventually require distribution.
Strategy 3: Coordinating NUA with Charitable Giving
How It Works: Use appreciated NUA stock for charitable donations rather than cash, avoiding capital gains tax entirely while generating charitable deduction.
Scenario: You receive $700,000 in company stock with $500,000 NUA. You plan to donate $100,000 to charity. Instead of selling $100,000 worth of stock (triggering $71,000 in capital gains tax at 20%), donate $100,000 worth of appreciated shares directly to your donor-advised fund. You get a $100,000 charitable deduction and avoid the $14,200 capital gains tax entirely.
Tax Benefit: $14,200 in avoided capital gains tax + $100,000 charitable deduction = combined benefit of $37,000-$50,000 depending on your tax bracket.
Best For: High-net-worth individuals planning significant charitable giving or considering a donor-advised fund.
Strategy 4: Stepped-Up Basis Planning (Estate Planning)
How It Works: Hold NUA stock in your estate and allow beneficiaries to receive a stepped-up cost basis at your death, eliminating capital gains tax on appreciation during your lifetime.
Scenario: At age 60, you take NUA distribution of $2,000,000 stock with $1,500,000 appreciation, paying $555,000 in ordinary income tax on cost basis. You hold the stock. At age 85, the stock has grown to $4,000,000. When you pass away, your heirs receive the stock with a stepped-up basis to $4,000,000. They can sell immediately with zero capital gains tax on the additional $2,000,000 appreciation.
Tax Benefit: The $2,000,000 in gains after your distribution escape capital gains tax entirely. At 20% rate, that's $400,000 saved for your heirs.
Best For: Older individuals with estate planning concerns, who don't need the stock sales proceeds during retirement.
Strategy 5: NUA with Opportunity Zone Investment Reinvestment
How It Works: Combine NUA strategy with Section 1045 stock sale to invest proceeds into Opportunity Zone funds, deferring capital gains and getting long-term appreciation benefits.
Scenario: Age 58, you take NUA distribution of company stock. After 13+ months, you sell $500,000 of stock (triggering capital gains tax). Instead of paying the tax immediately, you invest the proceeds into a designated Opportunity Zone investment within 180 days, deferring the tax and potentially eliminating 15% of the gains if held 10+ years.
Tax Benefit: Defer $100,000+ in capital gains tax, plus 15% of gains (additional $15,000-$30,000) potentially eliminated.
Best For: Investors willing to take alternative investment risks for significant tax deferral benefits.
Common Mistakes & How to Avoid Them
Mistake 1: Not Requesting In-Kind Distribution
Why People Make It: Many employees don't understand the difference between in-kind and cash distributions, or don't realize they need to explicitly request in-kind. They assume the plan will do it automatically or offer it by default.
Consequence: The plan liquidates all stock and sends cash. NUA treatment is completely lost. You now owe ordinary income tax on all $700,000 value, not just $200,000 cost basis.
How to Avoid: In your distribution election, explicitly state: "I elect Net Unrealized Appreciation treatment under IRC Section 402(e)(4)(J) and request in-kind distribution of all company stock shares." Confirm in writing with plan administrator.
Mistake 2: Rolling NUA Stock to an IRA
Why People Make It: Many advisors recommend rolling everything to an IRA automatically, without understanding that this destroys NUA treatment. The employee goes along with the recommendation.
Consequence: NUA treatment is lost forever. The stock becomes IRA-held, and all future withdrawals are ordinary income. The appreciation is no longer eligible for long-term capital gains treatment.
How to Avoid: Specifically instruct that company stock goes to your taxable brokerage account, NOT an IRA. If your advisor recommends an IRA, get a second opinion from someone with NUA expertise.
Mistake 3: Selling Within One Year
Why People Make It: Investors get nervous about concentration risk and want to quickly diversify, or stock drops significantly and they want to prevent further losses.
Consequence: While NUA shares are still treated as long-term capital gains after distribution (regardless of holding period), selling within 12 months of distribution can trigger complications with IRS reporting and looks inconsistent. Some may interpret short-term sales as indicating the investor didn't intend long-term capital gains treatment.
How to Avoid: Plan to hold NUA shares for at least 13 months before making significant sales. If you need to diversify urgently, do so in a different way (through tax-loss harvesting or dollar-cost averaging within the one-year window).
Mistake 4: Not Obtaining Cost Basis Documentation
Why People Make It: Investors assume the brokerage will have accurate cost basis information, or they don't realize how important it is to document immediately.
Consequence: Year later, brokerage has different cost basis than what plan administrator used. Discrepancies arise during tax preparation. IRS could question which is correct, potentially requiring amended returns.
How to Avoid: Obtain cost basis breakdown from plan administrator BEFORE distribution is processed. Create written record. Cross-reference with brokerage upon transfer. Address any discrepancies immediately in writing.
Mistake 5: Not Filing Form 4972
Why People Make It: Tax preparers miss this or aren't familiar with it. The requirement isn't always obvious.
Consequence: IRS may challenge the long-term capital gains treatment of NUA. You could owe back taxes, interest, and penalties.
How to Avoid: Work with a tax professional experienced in NUA. Make sure Form 4972 or similar documentation is filed with your return the year you take the NUA distribution. Include detailed documentation of cost basis and distribution amount.
Mistake 6: Not Distributing Other Plan Assets
Why People Make It: Investors want to keep some assets in the plan for tax deferral, and don't understand the lump-sum distribution requirement for NUA.
Consequence: Incomplete lump-sum distribution can disqualify NUA treatment. IRS may recharacterize the entire distribution as non-qualified.
How to Avoid: Understand that electing NUA requires distributing ALL plan assets in the same calendar year. You can roll non-company-stock assets to an IRA, but you must distribute them.
NUA vs. Alternative Strategies
| Strategy | Company Stock Treatment | Tax on Appreciation | Annual Complexity | Best For |
|---|---|---|---|---|
| Traditional IRA Rollover | All proceeds rolled, held in IRA | 100% ordinary income when withdrawn | Low | Investors wanting simplicity and deferral |
| NUA (Net Unrealized Appreciation) | In-kind distribution to taxable account | Long-term capital gains on appreciation (0%, 15%, or 20%) | High (must track cost basis and holding period) | Concentrated positions with significant appreciation |
| Roth Conversion | Converted to Roth, then grows tax-free | No tax on appreciation after conversion | Medium (one-time taxable event) | Younger investors with lower current income |
| Direct Stock Distribution + Diversification | Distributed as stock, then sold for diversification | Capital gains tax immediately on all appreciation | Medium | Investors who don't want to hold concentrated positions |
| Charitable Distribution | Distributed to qualified charity | No capital gains tax, charitable deduction | Low to Medium | Philanthropically-inclined investors |
When to Choose NUA
- You have significant unrealized appreciation (gains of $250,000+)
- The company stock has appreciated 2x or more from cost basis
- You're separating from service and can make the election
- Your current tax bracket is significantly higher than long-term capital gains rate
- You can hold the stock or manage diversification over time
- You understand the tax implications and have professional guidance
When NOT to Use NUA
- Company stock has minimal or negative appreciation
- You're in a lower tax bracket and expect higher rates in retirement
- You can't tolerate concentration risk in a single stock
- You need immediate liquidity and will sell all stock quickly anyway
- Your plan administrator doesn't support in-kind distributions
- You lack access to proper professional advice on implementation

Frequently Asked Questions
Net Unrealized Appreciation (NUA) is the difference between the cost basis and current value of company stock held in a 401(k) plan. When you separate from service, you can distribute the stock in-kind to a taxable brokerage account, paying ordinary income tax only on the cost basis, while the appreciation (NUA) is taxed as long-term capital gains when sold—potentially at a lower rate.
You can execute an NUA distribution only after you've separated from service (quit, retired, laid off, or terminated). Other qualifying events include reaching age 55 (with in-service distributions), death, or disability. The stock must be distributed in-kind from the qualified plan.
With a regular rollover to a traditional IRA, all proceeds remain tax-deferred until withdrawal, and all withdrawals are taxed as ordinary income. With NUA, you pay ordinary income tax immediately on the cost basis but defer long-term capital gains tax on the appreciation, which may be lower when you eventually sell.
Savings depend on the appreciation amount and your tax bracket. For example, if your NUA is $500,000 and your long-term capital gains rate is 20% versus ordinary income at 37%, you could save $85,000 in taxes if the holding period requirements are met.
After receiving the distributed stock, you must hold it for at least one year to qualify for long-term capital gains treatment on the appreciation. Sales within one year may be subject to short-term capital gains rates.
You can choose which assets to distribute. However, if you do an NUA distribution, you must also distribute the rest of the plan in accordance with IRC Section 402(e)(4)(J). Other investments in the plan must be distributed as a lump sum in the same calendar year.
Form 1099-R reports the distribution from the plan. Form 4972 is used to report long-term capital gains treatment of the NUA. You'll also use Schedule D to report the long-term capital gains when you eventually sell the stock.
No. NUA distributions must go to a taxable brokerage account or traditional IRA. If you roll to a traditional IRA, NUA treatment is lost. If you roll to a Roth, you lose NUA advantages and pay ordinary income tax on the full amount.
Risks include stock concentration (lack of diversification), having the $500,000+ sitting in one stock, market volatility, and the requirement that other plan assets be distributed in the same year. Additionally, if the stock declines after distribution, you've already paid ordinary income tax on the cost basis.
NUA can be beneficial even for high-earners because long-term capital gains rates (0%, 15%, or 20%) are typically lower than ordinary income tax rates (up to 37%). However, timing matters. If you're still working and can defer, waiting until retirement when your bracket is lower maximizes the benefit.
If you're age 72 and taking RMDs, the NUA distribution counts toward satisfying your RMD for that year. If the NUA distribution exceeds your RMD, the excess is taxed accordingly. Plan ahead with your tax advisor to coordinate timing.
Yes, if the plan participant dies, beneficiaries can still benefit from NUA by distributing the appreciated company stock in-kind. The cost basis steps up to fair market value at death, eliminating any appreciation that occurred before death.
Some plans restrict distributions to cash only. If your plan doesn't allow in-kind distributions of company stock, the NUA strategy isn't available. Check your plan documents or contact your plan administrator to determine if this option exists.
