When you leave an employer — whether due to retirement or a career change — it’s common to roll a 401(k) into an IRA. In many cases, that’s a smart and straightforward move. But if your retirement plan holds significant amounts of highly appreciated company stock, automatically rolling everything into an IRA could mean missing out on a valuable tax opportunity.
That opportunity is known as Net Unrealized Appreciation, or NUA — a little-known provision in the tax code that can potentially reduce the taxes you pay on company stock held inside an employer-sponsored retirement plan.
Understanding when (and when not) to use NUA can make a meaningful difference in your long-term after-tax wealth.
What Is Net Unrealized Appreciation?
Net Unrealized Appreciation refers to the increase in value of company stock held inside a qualified retirement plan — from the price paid by the plan to the stock’s value at the time it is distributed.
For example:
- Your employer’s plan purchased company stock for $100,000.
- The stock is now worth $1,000,000.
- The $900,000 increase is the “net unrealized appreciation.”
How — and when — that appreciation is taxed depends on how the stock is handled when you leave your employer.
Why NUA Can Be Tax-Advantaged
When assets are rolled into a traditional IRA, they continue growing tax-deferred. However, all future withdrawals — principal and growth alike — are taxed as ordinary income, regardless of whether the gains came from dividends, interest, or capital appreciation.
NUA offers a different path.
Instead of rolling company stock into an IRA, you may be able to:
- Transfer the company stock in-kind to a taxable brokerage account.
- Pay ordinary income tax only on the original cost basis of the shares.
- Defer taxes on the appreciation until the stock is sold.
- Pay long-term capital gains tax (currently capped at 20%) on the NUA rather than ordinary income tax.
This distinction can be significant for individuals in higher tax brackets.
Key Rules and Limitations to Know
The NUA strategy comes with strict requirements and important caveats:
- Only employer stock qualifies. Mutual funds, ETFs, or stock from other companies do not.
- Cost basis must be documented. Your employer or plan administrator must provide the original purchase price.
- Early distribution penalties may apply. If you separate from service before age 55, a 10% penalty could apply to the taxable portion.
- A lump-sum distribution is required. The entire retirement plan must be distributed within a single tax year. While the company stock goes to a taxable account, the remaining assets may still be rolled into an IRA.
Because the rules are rigid, even small missteps can disqualify the strategy.
A Dollars-and-Cents Example
Assume:
- Company stock makes up 90% of your 401(k)
- Cost basis: $100,000
- Market value: $1,000,000
Using NUA:
- You pay ordinary income tax on $100,000 now
- The $900,000 of appreciation is taxed later at capital gains rates when sold
Rolling into an IRA instead:
- No tax today
- Withdrawals in the future are taxed at ordinary income rates on the full amount
Depending on your tax bracket, this difference can translate into substantial tax savings over time.
Additional Planning Considerations
No Required Minimum Distributions (RMDs)
Once company stock is moved to a taxable account, it is not subject to RMDs, unlike IRA assets.
Ongoing Taxes
Dividends generated by the stock in a taxable account will be taxed annually.
Portfolio Concentration
If company stock represents a large portion of your net worth, NUA may complicate diversification. In some cases, rolling the stock into an IRA and selling it there — without immediate tax consequences — may offer more flexibility.
When NUA May Make Sense
NUA is often most effective when:
- Company stock represents a large portion of your retirement assets.
- The stock has significantly appreciated.
- You are in a high tax bracket.
- You have sufficient cash to pay the upfront tax.
- You are already well-diversified elsewhere.
There are also “niche” scenarios where NUA may be especially useful, such as:
- Needing immediate liquidity (e.g., funding a business venture).
- Having large capital loss carryforwards to offset gains.
- Coordinating with legacy tax provisions for certain retirees.
Estate Planning Implications
Unlike most taxable assets, NUA does not receive a full step-up in basis at death.
- Beneficiaries owe capital gains tax on the original NUA.
- Any appreciation after the stock’s distribution date does receive a step-up in basis.
- The stock may also be treated as “income in respect of a decedent” (IRD), which can affect estate and income taxes for heirs.
These nuances make coordination with estate planning especially important.
Is NUA Right for You?
There is no universal answer. The decision to use NUA depends on your:
- Tax bracket today and in retirement
- Concentration risk
- Cash flow needs
- Estate planning goals
- Ability to manage a potentially large tax bill
Because of the complexity — and the permanence of the decision — NUA should always be evaluated with a financial advisor and tax professional working together.
