What is net unrealized appreciation (NUA)?

Net unrealized appreciation (NUA) is the difference between the current market value of employer stock in your 401(k) and the original cost the plan paid for those shares (the cost basis). When you take a lump-sum distribution of your 401(k) and transfer the employer stock to a taxable brokerage account (rather than rolling it to an IRA), the NUA is taxed at the long-term capital gains rate — not ordinary income rates — when you eventually sell.

Who benefits most from the NUA strategy?

The NUA strategy is most beneficial when: (1) your company stock has grown significantly since the 401(k) purchased it — a large NUA relative to cost basis; (2) you are in a high ordinary income tax bracket (22%+), making the capital gains rate savings significant; (3) you need income in retirement or have a reason to sell the shares soon. If your company stock hasn't appreciated much, or if you plan to hold shares for a long time, rolling to an IRA may be simpler.

What are the risks of the NUA strategy?

Key risks include: concentrated stock risk (you're holding a single company's stock in a taxable account), the upfront ordinary income tax on the cost basis (paid immediately when you take the distribution), and the loss of tax-deferred compounding on the distributed amount. Additionally, the NUA strategy requires a lump-sum distribution — you cannot use it for partial distributions over multiple years.

Can I do the NUA strategy and also roll over the rest of my 401(k)?

Yes. Many investors use a combination approach: take the employer stock as an in-kind distribution (qualifying for NUA treatment) and roll over all other 401(k) assets to a traditional IRA. This maximises the NUA benefit on the appreciated stock while maintaining tax-deferred growth on the remaining assets.

Net Unrealized Appreciation (NUA) Strategy 2026 — How to Lower Tax on Company Stock in Your 401(k)

Net unrealized appreciation (NUA) is a lesser-known but powerful tax strategy for employees who hold significantly appreciated company stock inside their 401(k). Instead of rolling all 401(k) funds to an IRA at retirement, the NUA strategy lets you take the company stock as an in-kind distribution — paying ordinary income tax only on the original cost basis and long-term capital gains rates on all the appreciation when you eventually sell.

Key takeaway: If your employer stock inside your 401(k) has appreciated dramatically, the NUA strategy can result in lower taxes than rolling the stock to a traditional IRA and withdrawing it later (which would be taxed at ordinary income rates). The trade-off is a concentrated position in a single stock and an immediate tax bill on the cost basis.

How NUA Works — The Tax Math

When you take company stock out of a 401(k) under NUA rules, the IRS taxes the transaction in two parts:

Component	Amount	Tax Treatment
Cost basis	What the plan paid for the shares	Ordinary income tax, paid immediately when you take the distribution
NUA (net unrealized appreciation)	Current market value minus cost basis	Long-term capital gains tax, paid when you sell the shares
Additional appreciation after distribution	Gains after you receive the stock	Short or long-term capital gains (depending on holding period after distribution)

Example:

Your 401(k) holds 1,000 shares of your employer’s stock
Plan cost basis: $10/share × 1,000 = $10,000 (paid into the plan over your career)
Current market value: $80/share × 1,000 = $80,000
NUA = $80,000 - $10,000 = $70,000

Under NUA strategy:

Pay ordinary income tax on $10,000 cost basis in year of distribution
Pay long-term capital gains tax on $70,000 NUA when you sell the shares
For someone in a 32% ordinary income bracket and 15% LTCG bracket, the NUA saves: ($70,000 × 32%) - ($70,000 × 15%) = $11,900 in saved taxes

Under traditional IRA rollover (for comparison):

Roll $80,000 to IRA — no immediate tax
Withdraw from IRA later — all $80,000 taxed at ordinary income rates
At 32%: tax = $25,600
NUA strategy tax on same $80,000: $10,000 × 32% + $70,000 × 15% = $13,700
NUA saves $11,900

The Four Requirements for NUA Treatment

The IRS requires all four conditions to be met:

Lump-sum distribution: You must distribute the entire account balance from your employer’s plan in a single tax year (or the same tax year as a triggering event). You cannot take partial distributions.
Triggering event: You must have experienced one of these qualifying events:
- Separation from service (retirement, termination, resignation)
- Reaching age 59½
- Death
- Disability (for self-employed individuals only)
In-kind distribution: The employer stock must be distributed as actual shares — transferred directly to your taxable brokerage account. You cannot sell the shares inside the plan and take cash.
Participation for 5+ years: You must have participated in the plan for at least 5 tax years (this requirement applies to rollovers from plan assets — clarified under IRS rules).

Step-by-Step NUA Strategy Process

Request an in-kind distribution of employer stock from your 401(k) plan administrator — specify you want the shares distributed in kind, not sold.
Direct the stock to a taxable brokerage account (not an IRA). The brokerage must be able to receive in-kind transfers of employer securities.
Roll over non-employer assets from the same 401(k) to a traditional IRA in the same tax year.
Report the distribution: Your plan will issue a 1099-R. Box 1 = total distribution; Box 6 = NUA amount; Box 2a = cost basis taxed as ordinary income. The NUA in Box 6 is NOT included in Box 2a (it’s deferred until sale).
Hold and sell the employer shares in your taxable account when appropriate. The NUA is taxed at long-term capital gains rates regardless of how long you hold the shares after distribution. Additional appreciation after distribution uses the normal short/long-term holding period rules.

When NOT to Use NUA

Company stock has not appreciated much (small NUA = small benefit)
You are in the 10–12% tax bracket — ordinary income rate nearly equals LTCG rate, eliminating most benefit
You are in the 0% LTCG bracket (income under $47,025 single) — IRA rollover and distribution may be just as tax-efficient
You want to avoid concentrated single-stock risk and prefer immediate diversification
The cost basis is very high relative to current market value

NUA vs 1031 Exchange Comparison

Unlike a 1031 exchange (which applies to real estate), NUA is specific to employer securities in qualified plans. There is no equivalent “like-kind exchange” for employer stock — NUA is the only way to get capital gains treatment on 401(k) employer stock.
