Is NUA Worth It on Appreciated Company Stock? (w/Examples) + FAQs

This article reflects federal tax rules as of June 2026 and covers tax year 2026. Net Unrealized Appreciation is a federal income tax rule; state treatment varies, and is addressed in its own section below. Tax law changes — confirm current figures with the IRS or a licensed professional before you file or make a distribution.

Quick Answer

Yes — NUA is often worth it in 2026 when your company stock has gained a lot and your cost basis is low (roughly under 25–30% of value). You pay ordinary income tax now only on the basis, then long-term capital gains rates (0%, 15%, or 20%) on the appreciation.

Net Unrealized Appreciation (NUA) is a one-time tax election that lets you pull appreciated employer stock out of your 401(k) and pay the low long-term capital gains rate on the growth, instead of the ordinary income rate you would pay on every dollar coming out of an IRA. The catch is real: you owe ordinary income tax right now on the original cost of the shares, and one paperwork slip can wipe out the entire break. Used at the wrong time, with high-basis stock or a long time horizon, it can cost you more than a plain rollover.

The decision usually lands the day you retire or leave your job, and it is easy to lose by accident — most people roll their whole 401(k) into an IRA on autopilot and permanently forfeit the chance. One beancount.io analysis shows NUA saving more than $144,000 on a single $1 million stock position, yet the firm notes it is “one of the most powerful retirement tax strategies that almost nobody uses.”

What Net Unrealized Appreciation Actually Means

Net Unrealized Appreciation is the gap between what your employer stock is worth today and what it cost when it went into your retirement plan. In plain terms, NUA equals the current fair market value of the shares minus their cost basis — the price recorded when you or your employer first put them in the plan. If shares worth $400,000 today went in at a $60,000 cost basis, your NUA is $340,000.

This matters because of how the two pieces get taxed under Internal Revenue Code Section 402(e)(4) and IRS Notice 98-24. When you elect NUA and move the actual shares “in-kind” into a regular taxable brokerage account, you owe ordinary income tax that year on the cost basis only. The appreciation — the NUA — is not taxed until you sell, and when you do, it is taxed at long-term capital gains rates no matter how briefly you held the shares.

Here is why that is a big deal. Ordinary income tax rates reach 37% at the federal level in 2026, while long-term capital gains top out at 20%. Moving the bulk of a large gain from the 37% column to the 15% or 20% column is the entire point of the strategy. The consequence of not knowing this rule is steep: roll the same shares into an IRA and every future dollar — basis and growth alike — comes out as ordinary income for the rest of your life.

A common misconception is that NUA gives the shares a “step-up” or erases the tax. It does not. The growth is deferred and re-rated to a lower bracket, not forgiven. Your next step if you hold employer stock in a plan: ask your plan administrator in writing for the per-share cost basis of each lot before you make any distribution decision.

The Four Eligibility Rules You Cannot Get Wrong

NUA has sharp edges. Miss any one of these four federal requirements and the whole tax break collapses into ordinary income.

1. The Stock Must Be Employer Securities in a Qualified Plan

The shares must sit inside a qualified employer plan — a 401(k), an ESOP, or a profit-sharing or stock bonus plan — and they must be stock of the employer that sponsors the plan. IRAs and SEP-IRAs never qualify. The consequence of getting this wrong is total: if the employer stock is already inside an IRA, NUA is gone forever and cannot be restored. For example, Tom rolled his 401(k) to an IRA in 2024, then learned about NUA in 2026 — too late, because the shares lost their plan status. Your move: confirm the shares are still in the employer plan, not an IRA, before doing anything.

2. A Triggering Event Must Occur

You can only take an NUA distribution after one of four events: separation from service (retiring, quitting, or being laid off), reaching age 59½, total disability for a self-employed participant, or death (a beneficiary can elect NUA). Without a triggering event, the plan will not release the shares for this treatment. A misconception here is that “retirement age” alone counts — it does not; the event must be a qualifying one under the IRC Section 402 rules. Your move: pin down the exact date of your triggering event, because it starts the clock on the next rule.

3. The Distribution Must Be a Lump-Sum Distribution

This is where most NUA plans die. The IRS requires that the entire balance of the plan (and all similar plans with that employer) be emptied within a single tax year after the triggering event. You cannot dribble it out over two years. The consequence of breaking this rule is brutal: if your in-kind stock transfer settles December 28 and the leftover cash rolls over January 4, you have blown the lump-sum requirement and lost NUA on the entire balance. You can still split the destination — send the company shares to a brokerage account and roll the rest (mutual funds, cash) to an IRA — as long as both happen in the same calendar year. Your move: confirm in writing that the administrator can complete everything in one tax year.

4. The Stock Must Be Distributed In-Kind

The shares themselves must move from the plan trustee to a non-retirement brokerage account. If you sell the stock inside the plan and take cash, NUA is gone. A common mistake is swapping company stock for an index fund inside the 401(k) before leaving, fearing concentration — that sale resets the basis and can erase the NUA benefit. Your move: instruct the administrator to transfer the actual shares, not the cash value.

Which Situation Applies to You?

NUA is never one-size-fits-all. Use this to find the part of the decision that fits you.

You are retiring or leaving a job with low-basis company stock in a 401(k): You are the textbook candidate. Read the worked examples and the break-even section closely before you sign any rollover paperwork.
You are age 55–59 and separating from service: You may avoid the 10% early withdrawal penalty under the “Rule of 55” if you leave during or after the year you turn 55. Confirm your age at separation.
You are under 55 and already separated: The 10% early withdrawal penalty applies to the cost basis portion (not the full value) unless an exception fits. This often tips the math against NUA.
Your stock basis is high (over ~50% of value): NUA likely fails. The up-front ordinary income tax can exceed the future savings.
You inherited a 401(k) holding employer stock: NUA can still apply to you as a beneficiary, but inherited-IRA rollover decisions are final. See the beneficiary section.

Worked Example #1 — When NUA Clearly Wins

Meet Maria, age 60, separating from a public company in 2026. Her 401(k) holds $1,000,000 of company stock with a cost basis of $150,000, so her NUA is $850,000. She files single and her other income lands her gain in the 15% long-term capital gains bracket. The 2026 long-term capital gains brackets, confirmed by the IRS, are 0% up to $49,450 of taxable income (single), 15% up to $545,500, and 20% above that.

The NUA path: Maria pays ordinary income tax now on the $150,000 basis. At a 32% marginal rate, that is $48,000. When she later sells, she owes 15% long-term capital gains on the $850,000 NUA, which is $127,500. Her total federal tax is $175,500.

NUA Election — Maria’s Math	Federal Tax
Ordinary income tax now on $150,000 basis (32%)	$48,000
Long-term capital gains on $850,000 NUA (15%)	$127,500
Total federal tax	$175,500

The rollover path: If Maria instead rolls the full $1,000,000 to an IRA and withdraws it over time at her 32% rate, she pays roughly $320,000 in federal tax — every dollar is ordinary income. NUA saves her about $144,500, matching the beancount.io example. Her next step is liquidity: she needs roughly $48,000 in cash to cover the up-front tax without selling the very shares she is trying to protect.

Worked Example #2 — When NUA Is Not Worth It

Now meet David, age 58, separating in 2026. His 401(k) holds $400,000 of company stock, but his cost basis is high at $280,000, leaving only $120,000 of NUA. He is in the 24% bracket and would pay 15% on gains.

The NUA path: David pays 24% ordinary income tax now on the $280,000 basis, which is $67,200 — a painful up-front bill. He then owes 15% on the $120,000 NUA when he sells, or $18,000. His total is $85,200, and the $67,200 is due immediately.

High-Basis Stock — David’s Outcome	Federal Tax
Ordinary income tax now on $280,000 basis (24%)	$67,200
Long-term capital gains on $120,000 NUA (15%)	$18,000
Total if NUA elected	$85,200

Why the rollover wins for David: If he rolls the full $400,000 to an IRA and spreads withdrawals to stay in the 24% bracket, he pays about $96,000 total — but spread over many years, with decades of tax-deferred compounding in between. The deferral value of those years, plus avoiding a $67,200 tax bill in year one, makes the simple rollover the better call. The lesson: when basis is a large share of value, NUA can hurt. David’s next step is a spreadsheet comparing the after-tax growth of both paths over his real time horizon.

Worked Example #3 — Bracket Management with a Partial Election

Meet Susan, age 62, retiring in 2026 with $1,000,000 of company stock and a $200,000 basis. She does not need all the cash at once, so she elects NUA on only her lowest-basis lots and rolls the rest to an IRA. By distributing shares with $60,000 of basis in 2026 and keeping her ordinary income in the 22% band, she pays just $13,200 now. She then sells appreciated shares gradually, keeping each year’s gain inside the 15% capital gains bracket. This staged approach mirrors the “bracket management” strategy described by The Tax Adviser, which showed a $60,000 federal tax benefit from spreading distributions versus an all-at-once election. Susan’s next step is to ask whether her administrator can elect NUA on a per-lot basis — not all plans track basis this finely.

The Break-Even Rule of Thumb

The single best screen for “is NUA worth it?” is the cost basis as a percentage of current value. The lower the basis, the bigger the gap that escapes ordinary income tax, and the more NUA wins. As a rough guide, NUA is usually attractive when the basis is under 25–30% of the stock’s value, and usually a loser when the basis is above 50–60%.

The reason is simple arithmetic. You trade an up-front ordinary income tax on the basis for a lower capital gains rate on the appreciation. When basis is small, you pay a small up-front tax to convert a huge gain to a 15% or 20% rate. When basis is large, the up-front tax balloons while the rate-arbitrage shrinks. Two other factors push the answer:

Your bracket spread: The wider the gap between your ordinary rate (up to 37% in 2026) and your capital gains rate (0%, 15%, or 20%), the more NUA saves.
Your time horizon: A shorter time to selling favors NUA, because long stretches of tax-deferred IRA compounding can overtake the rate cut. The sooner you will sell, the better NUA looks.

Your next step before electing: build a side-by-side spreadsheet of total after-tax dollars under NUA versus a rollover, using your real basis, bracket, and selling timeline.

The 10% Early Withdrawal Penalty Trap

If you are under age 59½ when you take the distribution, a 10% early withdrawal penalty can apply — but only to the taxable cost basis portion, not the full stock value, as financial planning research confirms. There is a key escape hatch: under the “Rule of 55,” if you separate from service during or after the year you turn 55, the 10% penalty does not apply.

The consequence of ignoring this is a needless 10% surcharge on your basis. If David from Example 2 were only 52 and separated, his $280,000 basis would carry an extra $28,000 penalty on top of income tax — often enough to kill the strategy outright. Your next step: confirm your exact age at separation and whether the Rule of 55 covers you before electing.

How to Claim NUA — Forms, Steps, and Deadlines

NUA is not a box you check on your tax return; it is a sequence of distribution actions that must happen in order and on time.

Get your cost basis in writing. Ask the plan administrator for the per-share basis of each employer-stock lot. This is the number every later calculation depends on.
Confirm your triggering event date. This starts your one-tax-year window for the lump-sum distribution.
Instruct the administrator in writing to distribute the employer shares in-kind to a taxable brokerage account, and to roll all remaining plan assets to an IRA — both within the same calendar year.
Receive Form 1099-R. It should report fair market value as the gross distribution, the cost basis as the taxable amount, and the NUA in Box 6. The deadline for the plan to send it is January 31 of the year after distribution.
Report the basis as ordinary income on your Form 1040 for the distribution year. Tell your tax preparer an NUA election occurred, or the software may tax the appreciation as ordinary income by mistake.
Keep the 1099-R and basis statement permanently. You will need them years later, when you sell, to support the long-term capital gains treatment — this connects to your eventual Form 8949 and Schedule D reporting.

A narrow note on Form 4972: a separate 10-year averaging election on Form 4972 exists for lump-sum distributions, but it is restricted to participants born before January 2, 1936, so almost no current retiree qualifies. The cost of doing this yourself is mostly time; a CPA’s help on a large NUA election typically runs a few hundred to a few thousand dollars and is worth it when six figures of tax are at stake.

Federal vs. State: Does Your State Tax NUA?

NUA is a federal income tax rule, and states do not automatically follow it. Always settle the federal treatment first, then ask the separate question: how does my state handle the basis and the appreciation?

Federal NUA Treatment	State Wildcard
Basis taxed as ordinary income now; NUA taxed at federal capital gains rates (0/15/20%) when sold	Many states tax all of it as regular income, and several have no separate capital gains rate at all

Retirees in no-income-tax states such as Florida, Texas, Nevada, and Washington generally owe no state tax on either piece — a clean win. But a state with no preferential capital gains rate may tax the NUA at the same rate as ordinary income, shrinking the federal advantage. Some retirees deliberately time an NUA sale for a year after they have established residency in a no-tax state. Your next step: check your state’s specific rules on retirement-plan distributions and capital gains with the state’s revenue agency before you sell.

What About Inherited Employer Stock?

NUA survives the original owner’s death, which surprises many heirs. If you inherit a 401(k) holding employer stock, you can still elect NUA as the beneficiary. The decedent’s cost basis carries over for the ordinary income calculation, and the NUA itself stays taxable at long-term capital gains rates when you sell. Only the appreciation after the date of death generally receives a step-up. The fatal mistake is rolling the inherited assets into an inherited IRA — once that happens, NUA is permanently lost. Given how final this choice is, a beneficiary should talk to a qualified tax advisor before signing anything.

Mistakes to Avoid

Rolling the whole 401(k) into an IRA on the way out. This permanently destroys NUA; every future dollar becomes ordinary income.
Splitting the distribution across two tax years. A late-settling transfer breaks the lump-sum rule and voids NUA on the entire balance.
Selling the company stock inside the plan first. Taking cash instead of shares in-kind eliminates the NUA election.
Swapping company stock for funds before leaving. This resets the cost basis and shrinks or erases the NUA benefit.
Forgetting to tell your tax preparer. Without the NUA coding, the appreciation gets taxed as ordinary income by error.
Electing NUA on high-basis stock. A large up-front ordinary income tax can exceed the lifetime capital gains savings.
Ignoring the 10% penalty under age 55. The penalty on the basis can quietly turn a winning election into a loser.
Holding the concentrated position too long. A 40% stock drop can erase the tax savings you worked to capture.

Do’s and Don’ts

Do get the per-share cost basis in writing before any distribution, so your math is grounded in real numbers.
Do complete the full distribution in one tax year, because the lump-sum rule is all-or-nothing.
Do keep your 1099-R and basis statements for the life of the position, since you will need them when you sell.
Do consider a partial, per-lot election, because applying NUA only to low-basis lots can boost the net benefit.
Do check the Rule of 55, since it can spare you the 10% penalty if you separated at 55 or later.
Don’t sign rollover paperwork reflexively, because an IRA rollover ends NUA forever.
Don’t assume your state follows the federal rule, since many states tax the appreciation as ordinary income.
Don’t elect NUA with high-basis stock, because the up-front tax may outweigh the gain.
Don’t day-trade the shares after distribution, since post-distribution gains follow standard short- or long-term rules.
Don’t go it alone on a six-figure election, because one filing error can cost more than professional advice.

Pros and Cons

Pro — Lower tax rate on the gain: The appreciation is taxed at 0/15/20% instead of up to 37%, which is the core benefit.
Pro — Immediate diversification: Moving shares out lets you sell a concentrated position, reducing single-stock risk.
Pro — No required minimum distributions on the moved shares: Once in a brokerage account, the stock is not subject to IRA RMD rules.
Pro — Estate flexibility: Heirs may get a step-up on post-distribution appreciation, while NUA itself keeps capital gains treatment.
Pro — Bracket control: A staged, per-lot election lets you manage which year and bracket you realize income in.
Con — Up-front tax bill: You owe ordinary income tax on the basis immediately, which requires cash on hand.
Con — Possible 10% penalty: Under age 55 at separation, the basis can carry a 10% surcharge.
Con — Concentration risk: The shares sit in one company’s stock, and a price drop can erase the tax savings.
Con — Lost tax-deferred compounding: Money outside the IRA no longer grows tax-deferred, which hurts over long horizons.
Con — Irreversible and error-prone: One paperwork mistake voids the election permanently.

What to Do Next

Before you touch your 401(k), request the per-share cost basis of your employer stock from the plan administrator in writing.
Confirm your triggering event and your age at separation to check the lump-sum window and the Rule of 55.
Run a side-by-side after-tax comparison of NUA versus a full IRA rollover, using your real basis, bracket, and selling timeline.
If the math favors NUA, instruct the administrator to distribute shares in-kind and roll the rest to an IRA within the same tax year.
Tell your tax preparer about the election, keep your Form 1099-R, and consult a CPA or tax attorney before acting when six figures of tax are on the line. This article is educational and is not a substitute for advice on your specific situation.

FAQs

What is Net Unrealized Appreciation? Net Unrealized Appreciation is the difference between your employer stock’s current market value and its cost basis inside a retirement plan. Under IRC Section 402(e)(4), the appreciation can later be taxed at long-term capital gains rates instead of ordinary income rates for tax year 2026.

Is NUA worth it? Yes, usually when your cost basis is low (under about 25–30% of value), your tax bracket is high, and you plan to sell within a few years. It is often not worth it for high-basis stock or very long time horizons.

How is the cost basis taxed under NUA? As ordinary income in the year of distribution, at rates up to 37% for tax year 2026. Only this basis portion is taxed up front; the appreciation is deferred until you sell the shares.

What tax rate applies to the NUA itself? Long-term capital gains rates of 0%, 15%, or 20% for tax year 2026, depending on your taxable income, plus a possible 3.8% net investment income tax for high earners.

Does the 10% early withdrawal penalty apply to NUA? Yes, if you are under 59½, but only on the cost basis portion. The penalty does not apply if you separated from service during or after the year you turned 55, under the Rule of 55.

Can I elect NUA if my stock is already in an IRA? No. Once employer stock is rolled into an IRA, NUA treatment is permanently lost. The shares must come directly from a qualified employer plan such as a 401(k) or ESOP.

Do I have to use NUA on all my shares? No. You can apply NUA only to your lowest-basis lots and roll higher-basis lots into an IRA, if your plan administrator tracks basis by lot. This per-lot choice can increase your net benefit.

What form reports an NUA distribution? Form 1099-R reports it, with the NUA amount shown in Box 6 and the cost basis as the taxable amount. You report the basis as ordinary income on your Form 1040 for the distribution year.

Can beneficiaries use NUA on inherited company stock? Yes. A beneficiary can elect NUA on inherited employer stock; the decedent’s basis carries over for ordinary income, and the NUA keeps capital gains treatment. Rolling the assets into an inherited IRA destroys this option.

Does my state tax NUA the same way as the IRS? Not necessarily. Many states tax the appreciation as ordinary income or lack a preferential capital gains rate. No-income-tax states like Florida and Texas impose no state tax — confirm your own state’s rules before selling.

Is the lump-sum distribution required in one year? Yes. The entire plan balance must be distributed within a single tax year after a triggering event. Spreading it across two calendar years breaks the rule and voids NUA on the full balance.

Can I split where the distribution goes? Yes. You can send the company shares in-kind to a taxable brokerage account and roll the remaining assets to an IRA, as long as both transactions finish within the same tax year.
