Do Not Roll Over Your Company Stock Until You Understand Net Unrealized Appreciation
If you are retiring with your employer’s stock inside your 401k, the standard rollover advice can be wrong for that one piece of your account. Net unrealized appreciation, usually shortened to NUA, is a provision that lets you take those shares out of the plan in kind rather than rolling them into an IRA. You pay ordinary income tax on what the shares originally cost the plan. The growth on top of that gets long-term capital gains treatment when you sell, no matter how long you have held it. Roll the shares into an IRA instead and every dollar eventually comes out as ordinary income.
The election has strict sequencing rules, and a routine rollover destroys it permanently. Nobody is required to warn you first.
I am Ron McCoy, founder of Freedom Capital Advisors, a Florida-registered investment adviser. I have been in this industry for nearly 40 years, independent and fiduciary since 2012. NUA is the single most expensive thing I watch people give away by accident, and they give it away by doing the normal thing at the normal time.
The Mechanism
Your 401k bought company stock over the years you worked there. The plan paid some price for those shares. That is the cost basis. The shares are worth more now. The difference between what the plan paid and what they are worth on the day they leave the plan is the net unrealized appreciation.
Two paths, and they are taxed in completely different ways.
Roll it to an IRA. Nothing is taxed today. The account grows tax-deferred. Every dollar you eventually withdraw, basis and growth alike, is taxed as ordinary income. Required minimum distributions apply once you reach the age they start.
Take the shares in kind under NUA. You pay ordinary income tax this year on the cost basis only. The appreciation is not taxed at distribution. The shares land in a regular taxable brokerage account. When you sell them, the NUA portion is taxed at long-term capital gains rates regardless of how long you actually held the shares. Anything the stock gains after the distribution is taxed as a normal capital gain, long or short term depending on how long you held it after it came out.
The whole benefit lives in the gap between ordinary income rates and long-term capital gains rates. The bigger the appreciation relative to the basis, the bigger the gap gets.
What That Looks Like With Numbers
Hypothetical, and simplified to make the mechanism visible.
Say the position is worth $1,000,000 and the plan’s cost basis is $150,000. The NUA is $850,000. Assume a 32% ordinary rate and a 15% long-term capital gains rate.
Under NUA, you pay ordinary income tax on the $150,000 basis in the distribution year, which is $48,000. When you later sell, the $850,000 of appreciation is taxed at 15%, which is $127,500. Total tax, roughly $175,500.
Roll the same position into an IRA and the full $1,000,000 comes out as ordinary income over time. At 32%, that is $320,000.
Now flip the basis. Same $1,000,000 position, but the plan’s cost basis is $700,000 and the NUA is only $300,000. Under NUA you owe ordinary income tax on $700,000 up front, which is $224,000 due this year, before you have sold a share. The rollover looks far better, and it is not close.
That comparison ignores the value of deferral, which is real and which favors the rollover. The point is not the exact dollar figures. The point is that the answer flips entirely based on the ratio of basis to value, and there is no way to know which side you are on without pulling your actual basis from the plan.
The Four Events That Open the Door
NUA is only available in connection with a lump-sum distribution, and a lump-sum distribution has to follow one of four triggering events:
- You separate from service
- You reach age 59 and a half
- You become disabled
- You die
Lump sum here means the entire balance of the plan has to come out by December 31 of the year you do the NUA transaction. Not the company stock portion. The whole account. You can send everything else to an IRA in the same year and take only the company stock in kind, but the plan has to be emptied within that single tax year.
What Destroys the Election
This is where people lose it, and they lose it quietly.
A partial distribution in an earlier year. If you took money out of the plan after a triggering event and did not complete a lump-sum distribution that year, you are locked out until the next triggering event occurs. Someone who separated from service at 54 and took a small withdrawal has burned that trigger. They wait until 59 and a half for another one.
Rolling the stock into an IRA. Once those shares are inside an IRA, the NUA is gone. There is no undo. The appreciation you could have taxed at capital gains rates is now ordinary income forever.
Not finishing inside the calendar year. Start the distribution in December and let it spill into January and the lump-sum requirement fails.
The reason this catches so many people is that the default path is a full rollover to an IRA. It is what the plan recordkeeper offers, it is what most rollover paperwork is designed to do, and it is the correct answer for almost every other asset in the account. The company stock is the exception, and nothing in the process stops to tell you that.
When NUA Is the Wrong Answer
The strategy gets sold harder than it deserves. It is genuinely wrong in several common situations.
When the basis is high relative to the value. The up-front ordinary income tax is calculated on the basis. A high basis means a large bill this year in exchange for a smaller benefit later.
When you are under 55 and separating from service. The 10% early withdrawal penalty applies to the cost basis portion of the distribution. The NUA itself escapes it, but the basis does not, and that penalty comes on top of ordinary income tax.
When the distribution year is already a high-income year. The basis stacks on top of everything else you earned. Taking the distribution in a high-earning final year of work rather than the following year can cost real money for no reason other than timing.
When you do not need the money for a long time. Decades of tax-deferred compounding inside an IRA has value that a one-time rate arbitrage may not beat.
When it keeps you concentrated. This is the one nobody says out loud. NUA is a tax benefit that pays you to hold a large position in a single company’s stock, and holding a large position in a single company’s stock is how people lose retirements. The tax tail should not wag the risk dog. If taking NUA means carrying 40% of your net worth in one stock for another decade, the tax savings may be the most expensive money you ever made. I wrote about how to think about that tradeoff in the four ways out of a concentrated stock position.
Two Details Most People Never Hear
You can cherry-pick the lots. You are not forced to apply NUA to every share. You can take the lowest-basis shares in kind, where the benefit is largest, and roll the higher-basis shares into the IRA. That flexibility turns a yes-or-no decision into a sizing decision, and it is where most of the value gets captured.
The NUA does not get a step-up at death. If you hold the shares until you die, your heirs do not receive stepped-up basis on the NUA portion. It is treated as income in respect of a decedent and stays taxable at capital gains rates when they sell. Appreciation that happened after the distribution does get stepped up. This matters if your plan was to take NUA and never sell, because that plan does not work the way people assume it does.
What To Do Before You Sign Anything
Call the plan and get the cost basis of the company stock in writing. Not the current value. The basis. Everything downstream depends on that one number and most people have never seen it.
Then run both paths with your CPA before any paperwork moves, in the same conversation, with your actual bracket and your actual timeline. This is not a decision to make from a rule of thumb, and it is not reversible.
Frequently Asked Questions
What is net unrealized appreciation?
Net unrealized appreciation is the difference between what your 401k plan paid for your employer’s stock and what those shares are worth when they are distributed from the plan. If you take the shares in kind rather than rolling them over, you pay ordinary income tax on the cost basis in the year of distribution, and the appreciation is taxed at long-term capital gains rates when you sell.
Do I have to hold the stock for a year to get long-term capital gains treatment on the NUA?
No. The NUA portion receives long-term capital gains treatment regardless of how long you held the shares, including if you sell the day after the distribution. Only the appreciation that occurs after the distribution is subject to the normal holding period test.
Can I use NUA on some shares and roll the rest into an IRA?
Yes. You can apply NUA to selected lots, typically the ones with the lowest cost basis where the benefit is greatest, and roll the remaining shares and the rest of the account into an IRA. The entire plan balance still has to be distributed within the same tax year.
What happens if I already rolled my company stock into an IRA?
The NUA election is gone and cannot be recovered. Once the shares are in an IRA, all future withdrawals are taxed as ordinary income. This is why the decision has to be made before the rollover, not after.
Is the NUA subject to the 3.8% net investment income tax?
The NUA itself is not subject to the net investment income tax at the time of distribution. Gains that accrue after the distribution can be, depending on your income and holding period. Your CPA should confirm how this applies to your return.
Get the Basis Number First
If you are approaching a retirement date with company stock in your plan, the useful first step is finding out what the plan paid for those shares. That single number determines whether NUA is worth several hundred thousand dollars to you or worth nothing at all.
We work through that math with people before any rollover paperwork gets filed, alongside their CPA, and we are independent, so we have nothing to sell you on either side of the answer.
