Net Unrealized Appreciation

The lever for a client who's retiring on a pile of appreciated company stock

A Tax Alpha Companies playbook for CPAs

The default move that quietly costs a fortune

A client spends thirty years at a company and retires with a 401(k) full of that company's stock — often bought for a few dollars a share and now worth many times that. The near-universal advice is to roll the entire 401(k) into an IRA. It's tidy, it's tax-deferred, and for the appreciated employer stock, it can be a serious mistake.

Roll the stock into an IRA and every future dollar that comes out — basis and decades of appreciation alike — is taxed as ordinary income. The client converts what could have been long-term capital gain into ordinary income on the entire position, and locks in the higher rate for life.

The net unrealized appreciation (NUA) rules offer a different path for the client with the right facts — one that taxes the appreciation as capital gain instead.

How NUA works

When a client takes a qualifying lump-sum distribution from an employer plan and takes the employer securities in kind (as actual shares moved to a taxable brokerage account, not sold and not rolled), the tax splits in two:

• The cost basis of the shares — what the plan paid for them — is taxed as ordinary income in the year of the distribution.
• The net unrealized appreciation — the gain above that basis, built up inside the plan — is not taxed at distribution. It is taxed only when the client later sells the shares, and it is taxed at long-term capital-gains rates — regardless of how long the shares are actually held after the distribution.

Any further appreciation after the shares leave the plan is taxed under normal rules (long-term or short-term depending on the post-distribution holding period). But the big embedded gain — the NUA itself — is permanently converted from ordinary-income treatment to capital-gains treatment.

For a client whose employer stock has a low basis and large appreciation, that spread is the whole game. On a $2,000,000 position with a $200,000 basis, the ordinary-income hit falls on $200,000, and $1,800,000 of gain waits to be taxed at capital-gains rates on sale — instead of the entire $2,000,000 being taxed as ordinary income as it leaves an IRA over time.

The requirements — and they are strict

NUA is unforgiving. To qualify:

• A lump-sum distribution. The entire balance of the plan must be distributed within a single tax year, following a triggering event: separation from service, reaching age 59½, disability, or death. Distribute part of the account, or spread it across two tax years, and the lump-sum treatment is blown.
• Employer securities. The strategy applies only to stock of the employer held in the plan, taken in kind.
• No disqualifying prior distribution. A previous in-service distribution or partial rollover can disqualify the lump-sum treatment. The account has to be intact going into the distribution year.
• The NUA election is made by taking the shares in kind rather than rolling them; the plan reports the basis (ordinary-income) amount, typically on Form 1099-R.

Get the mechanics wrong — roll first and take stock later, or take a partial distribution — and the opportunity is gone.

The costs to weigh

NUA is not automatically the better answer. It carries real costs that have to be modeled against a straight IRA rollover:

• Basis is taxed now, out of pocket. The ordinary-income tax on the basis is due in the distribution year, paid from other funds. The larger the basis, the larger that upfront cost — and the weaker the case for NUA.
• The under-59½ penalty. If the client is under 59½ and the triggering event is separation from service, a 10% early-distribution penalty can apply to the basis portion (the amount taxed as ordinary income). This narrows the strategy for early retirees.
• Loss of tax deferral on the stock. Inside an IRA, the whole position keeps growing tax-deferred. With NUA, the shares sit in a taxable account, where future dividends and any post-distribution gains are currently taxable.
• NIIT and state tax. The eventual capital gain on sale can attract the 3.8% net investment income tax and state income tax — real, if still generally lower than ordinary rates.
• Concentration risk. Holding a large single-stock position for tax reasons is its own risk; the tax tail shouldn't wag the portfolio.

The break-even turns on the ratio of appreciation to basis and the spread between the client's ordinary and capital-gains rates. A low basis and a long-appreciated position favor NUA strongly; a high basis often tips the other way.

Once it's gone, it's gone

The most important operational point: the moment the employer stock is rolled into an IRA, NUA is lost — permanently. There is no undo. This is why the decision belongs at the exact moment of separation or retirement, before any rollover paperwork is signed. A client who "temporarily" rolls everything to an IRA to sort it out later has already forfeited the strategy.

That timing is what makes NUA a fourth-quarter conversation for a client who is about to retire: the distribution has to be planned, the triggering event and the single-tax-year lump-sum requirement have to line up, and the ordinary-income tax on the basis has to be budgeted for the year it lands.

Who this fits

A strong candidate:

• Retiring or separating from a company where they hold highly appreciated employer stock in a 401(k) or ESOP
• Low basis relative to current value (the higher the appreciation ratio, the better)
• Age 59½ or older, or otherwise clear of the early-distribution penalty on the basis
• Able to pay the ordinary-income tax on the basis from outside funds
• Comfortable managing (and eventually diversifying) a concentrated position

A poor candidate:

• High basis relative to appreciation — the ordinary-income cost swamps the benefit
• Under 59½ separating from service, where the penalty hits the basis
• Needs to keep everything tax-deferred and can't fund the upfront tax
• Would be forced to hold a dangerous concentration purely for the tax result

The practitioner's checklist

1. Identify clients retiring or separating with employer stock in a qualified plan — this only surfaces if you ask.
2. Pull the cost basis of the employer shares and compute the appreciation-to-basis ratio.
3. Confirm a qualifying lump-sum distribution is possible — entire balance, one tax year, triggering event, no disqualifying prior distribution.
4. Model NUA versus a straight IRA rollover, including the upfront ordinary tax on basis, the eventual capital-gains tax, NIIT, and state tax.
5. Check the client's age and the 10% penalty exposure on the basis.
6. Sequence the mechanics: take the stock in kind, roll (if desired) the rest of the account — never roll the stock first.
7. Plan for diversification of the concentrated position over time, capital-gains cost included.

Talk it through

NUA is one of those levers that only exists at a single moment — the retirement or separation — and disappears the instant the stock is rolled the wrong way. If you have a client approaching retirement with a large position in their own company's stock, it's worth running the numbers before any rollover is signed.
