NUA converts that growth to capital gains instead.","category":"finance","date":"August 19, 2026","author":"ByteLedger Team","content":"<span class=\"dropcap\">Y</span>ou are leaving a company where you have worked for twenty years, and a meaningful slice of your 401(k) is in that company's stock. It cost the plan $80,000 over the years and it is now worth $400,000. The standard advice — roll the whole 401(k) into an IRA — is usually right and here may cost you a great deal of money.\n\nNet unrealized appreciation is a provision that treats the $320,000 of growth differently from everything else in the account. Used correctly it converts that growth from ordinary income into long-term capital gain. Used carelessly, or simply overlooked, the option disappears the moment the rollover completes.\n\n## What changed in 2026\n\n- **Concentrated employer positions got more attention** as a risk-management topic, which brought NUA back into planning conversations it had drifted out of.\n- **Rollover defaults kept working against it.** Automated separation processes frequently move everything to an IRA by default, and the paperwork rarely flags what that forecloses.\n- **Capital gains and ordinary rate brackets moved**, changing the arithmetic at the margins and making the \"is it worth it\" calculation genuinely worth re-running.\n- **The rules themselves did not change.** NUA is long-standing and stable. What changes is your basis, the share price, and your bracket.\n\n## How it works\n\nTake a lump-sum distribution of your entire plan balance, moving the employer stock *in kind* into a taxable brokerage account rather than an IRA. Two separate things then happen:\n\n**The cost basis is taxed now, as ordinary income.** In the example, $80,000 is added to your income for that year. If you are under 59½, an early distribution penalty may apply to that portion.\n\n**The appreciation is not taxed until you sell.** The $320,000 of NUA is taxed as *long-term* capital gain whenever you sell the shares — regardless of how long you actually hold them afterwards. Sell the next day and it still qualifies for long-term treatment.\n\nEverything else in the plan can be rolled into an IRA as normal. It is only the employer stock that receives this treatment, and only if the whole account is emptied within one tax year.\n\n## When it is worth it\n\n| Factor | Favours NUA | Favours IRA rollover |\n| --- | --- | --- |\n| Basis as % of value | Low | High |\n| Your ordinary rate now | Lower | Higher |\n| Expected rate in retirement | Higher | Lower |\n| Cash to pay the upfront tax | Available outside the plan | Not available |\n| Need to diversify quickly | Yes — capital gain rate applies | Selling inside an IRA is untaxed |\n| Estate considerations | Heirs may benefit | Simpler |\n\nThe dominant variable is the ratio of basis to current value. Stock with $80,000 basis and $400,000 value has 20% basis — a strong NUA candidate. Stock with $300,000 basis and $400,000 value has 75% basis, and you would pay ordinary tax on most of the position to shelter a modest gain. Not worth it.\n\nThe second variable is what you would otherwise face. Everything in a traditional IRA eventually comes out as ordinary income, including via [required minimum distributions](/blog/required-minimum-distributions-2026) you may not want. NUA takes a known bill now in exchange for a lower rate later on the growth.\n\nA frequently overlooked point: a concentrated position in your former employer's stock is a genuine risk, and NUA makes diversifying *cheaper* rather than more expensive. Selling inside an IRA costs nothing immediately but converts everything to future ordinary income. Selling NUA shares in a taxable account costs capital gains rates. If you want out of the position, NUA is often the better route to that exit.\n\n## Getting the mechanics right\n\nThe requirements are unforgiving and mistakes are generally not fixable.\n\n**A triggering event must have occurred** — separation from service, reaching 59½, disability, or death.\n\n**The distribution must be a lump sum**, emptying the entire plan balance within one calendar year. A partial distribution in December and the rest in January disqualifies it.\n\n**The stock must move in kind.** Shares transfer to a taxable brokerage account as shares. If the plan sells them and distributes cash, there is no NUA.\n\n**Nothing goes to an IRA first.** This is where it usually goes wrong. Once employer stock lands in an IRA it is IRA money permanently, and no correction restores the treatment.\n\nTell your plan administrator explicitly that you intend to use NUA before initiating anything. Default processing does not do this, and the person handling your paperwork may not know the term.\n\n## Common mistakes\n\n- **Rolling everything into an IRA on autopilot.** The single most common and least reversible error.\n- **Splitting the distribution across two tax years.** Disqualifies the lump sum.\n- **Letting the plan liquidate the shares.** Cash distributions have no NUA.\n- **Applying it when basis is high.** You pay ordinary tax on most of the position to save on a small gain.\n- **No cash to pay the upfront tax.** Selling shares to cover it triggers gains and undercuts the strategy.\n- **Forgetting the early-distribution penalty.** Under 59½, it can apply to the basis portion.\n- **Ignoring state tax treatment.** State rules on capital gains vary and change the outcome.\n\n## FAQ\n\n**What happens to the shares after distribution?**\nThey sit in a taxable brokerage account. The NUA amount is taxed as long-term gain when sold. Any *additional* appreciation after distribution follows normal holding-period rules — so gains beyond the NUA figure need a year to qualify as long-term. [Cost basis explained](/blog/cost-basis-explained-2026) covers tracking the two layers.\n\n**Can I do this with only part of the stock?**\nYou can elect NUA treatment on some shares and roll the rest, but the lump-sum requirement still applies to the plan as a whole. Partial elections are possible; partial distributions are not.\n\n**What if the stock drops after I distribute?**\nYou have already paid ordinary tax on the basis, and a later sale below the NUA figure produces a smaller gain. A fall below basis creates a capital loss. The upfront tax is not refunded, which is the risk in taking a known bill for an uncertain benefit.\n\n**Does this work with ESPP or RSU shares?**\nNUA applies to employer securities held inside a qualified retirement plan. Shares in a taxable account from an [ESPP](/blog/espp-discount-explained-2026) or vested RSUs are already taxable-account assets with their own rules.\n\n## Where to go next\n\nFor the distributions NUA helps you avoid later, read [required minimum distributions](/blog/required-minimum-distributions-2026). For the rate side of the calculation, [capital gains tax explained](/blog/capital-gains-tax-explained-2026), and for how basis tracking works after distribution, [cost basis explained](/blog/cost-basis-explained-2026).\n\nThis is general information, not tax advice. NUA elections are effectively irreversible and the arithmetic is specific to your basis, bracket, and state; consult a qualified tax professional before initiating a distribution.","hue":292,"metaTitle":"Net Unrealized Appreciation: Company Stock Tax Break","metaDescription":"How net unrealized appreciation turns employer stock gains into capital gains, what triggers eligibility, and why an IRA rollover destroys the option for good.","keywords":["net unrealized appreciation","nua tax strategy","company stock 401k","employer stock distribution","nua vs ira rollover","lump sum distribution nua","concentrated stock position","retirement tax planning 2026"],"tldr":["**NUA converts appreciation from ordinary income to long-term capital gain** — the tax rate difference on a large position can be substantial.","**You pay ordinary income tax on the cost basis immediately** — that upfront bill is the price of admission and it is due in the year you distribute.","**It only works on a lump-sum distribution after a triggering event** — separation, disability, death, or reaching 59½, and the whole plan must empty in one tax year.","**Rolling into an IRA first forfeits it permanently** — this is the most common and least reversible mistake in the whole strategy.","**Skip:** NUA when the appreciation is small relative to basis.
