NUA Election on 401(k) Company Stock: The Million-Dollar Decision Most Participants Never Hear About
What NUA actually is
NUA stands for Net Unrealized Appreciation. It's an IRS provision (IRC Section 402(e)(4)) that applies when employer stock is held inside a qualified retirement plan like a 401(k) or ESOP.
Here's the setup. You worked at a publicly-traded company for 20 years. Through 401(k) contributions and employer match, your account accumulated company stock worth $500,000 today. Your cost basis (what was originally paid for those shares) is $50,000. The Net Unrealized Appreciation is $450,000 — the embedded gain.
Under a normal rollover, you'd roll the entire 401(k) (including company stock) into a Traditional IRA. Every dollar that later comes out of that IRA is taxed as ordinary income at your marginal rate — typically 22-32% federal plus state.
The NUA election lets you do something different:
- Distribute the employer stock in-kind (the actual shares) to a regular taxable brokerage account, not an IRA.
- Roll the rest of the 401(k) (non-employer-stock assets) into an IRA normally.
- Pay ordinary income tax only on the $50K cost basis in the year of distribution.
- The $450K of appreciation is now outside the IRA wrapper — sitting as taxable stock with a built-in unrealized gain.
- When you sell the stock, the $450K gain is taxed at long-term capital gains rates (0%, 15%, or 20% federal), not ordinary income.
What the savings actually look like
The math comes from the gap between ordinary income rates and long-term capital gains rates:
| Bracket scenario | Ordinary income rate | LTCG rate | Federal tax saved on $450K NUA |
|---|---|---|---|
| MFJ, $211K-$403K taxable | 24% | 15% | $40,500 |
| MFJ, $404K-$512K taxable | 32% | 15% | $76,500 |
| MFJ, $512K-$768K taxable | 35% | 15% | $90,000 |
| MFJ, $768K+ taxable | 37% | 20% | $76,500 |
This is just the federal piece. State savings stack: California taxes both ordinary and capital gains at the same 9.3% top rate, so the state benefit is small in CA. Most other states tax LTCG more favorably than ordinary income — meaningful additional savings.
Two further benefits that often dwarf the headline number:
- Step-up basis at death on post-distribution appreciation. The pre-distribution NUA does NOT receive step-up (it's "income in respect of a decedent"), but anything that appreciates after the distribution date does get a step-up if held to death.
- No future RMDs on the stock. Money in taxable brokerage has no RMDs, no distribution requirements, no IRMAA-spike risk from forced withdrawals.
The strict eligibility rules — do NOT mess these up
NUA is powerful but has narrow eligibility. To qualify, you must meet ALL of these:
- Triggering event. Separation from service (retiring or leaving the company), reaching age 59½, total disability, or death.
- Lump-sum distribution. The entire balance of all qualified plans of the same type with the employer must be distributed in a single tax year. Partial distributions kill eligibility.
- Direct distribution of stock. The employer stock must come out as actual shares, not as cash. If the plan sells the stock and gives you cash, NUA is gone.
- Single tax year. The entire distribution must happen within one calendar tax year.
One specific mistake I see constantly: a participant rolls the 401(k) into a Traditional IRA "to think about it later." NUA is permanently eliminated the moment the stock enters an IRA. There is no do-over.
Critical: Do not roll your 401(k) into an IRA if you have meaningful appreciated employer stock until you've evaluated NUA. This is the most expensive default mistake in 401(k) rollover decisions.
When NUA is the right move — and when it isn't
NUA is right when ALL of these are true:
- You have meaningful employer stock in your 401(k) — typically $100K+ of accumulated value
- The cost basis is low relative to current value — under 50% is a strong indicator
- You have a triggering event coming or already happened
- You can hold the stock for at least one year (to qualify for LTCG rates on the future sale)
- Your expected ordinary income tax bracket in retirement is meaningfully higher than the LTCG bracket — typically true for almost all high-balance retirees
NUA is NOT right when:
- Cost basis is close to current value (small embedded gain, small savings)
- You need to sell the stock immediately and can't hold for at least one year
- You're heavily over-concentrated in employer stock and the right risk-management answer is to diversify immediately
- You don't have a clean triggering event yet
The decision is almost always one-shot. Once you roll without electing NUA, the option is gone forever.
How NUA pairs with other strategies
NUA + Roth conversions
The typical sequence I structure for executives with significant company stock positions:
- Year of separation: Distribute the employer stock as NUA. Pay ordinary tax on the cost basis (relatively small). Roll the rest of the 401(k) to an IRA.
- Subsequent years: Convert IRA dollars to Roth deliberately under a normal multi-year conversion ladder.
- Sale of NUA shares: Sell when needed at LTCG rates. Time sales to coordinate with other income (low-income year = 0% LTCG opportunity if total taxable income stays under $98,900 MFJ).
- If held to death: Heirs receive step-up basis on post-distribution appreciation.
NUA + diversification via MYGA or FIA
The biggest risk with NUA is concentrated single-stock exposure. If you have $500K in one employer's stock, the company-specific risk is enormous. After NUA, I often recommend selling a portion of the stock and moving the proceeds into a diversified position — including potentially a portion into a MYGA or FIA to lock in guaranteed income for the principal-protected portion of the portfolio. See my annuity review center for current options.
NUA + charitable strategy
Highly-appreciated NUA shares can be donated directly to a Donor-Advised Fund or directly to a 501(c)(3) charity. You get a fair-market-value deduction AND avoid the capital gains tax on the appreciation. For charitably-inclined participants, this turns the NUA into a tax-efficient giving vehicle.
What to do if you have employer stock and are within 5 years of separation
The priority list:
- Pull your 401(k) statement and find the cost-basis breakdown for employer stock. Most plan administrators can give you a separate "NUA-eligible cost basis" number. If they can't, keep pushing — that's a yellow flag.
- Calculate the embedded NUA. Current value minus cost basis = NUA. If it's $100K+, this is worth exploring seriously.
- Project your expected ordinary income tax bracket in retirement. If it's 22%+, NUA is likely in play.
- Project your LTCG bracket. 0%, 15%, or 20% federal. The gap between this and your ordinary rate is your per-dollar savings.
- Get specific quotes from a tax professional on the NUA distribution mechanics. Coordinate with your plan administrator on timing, share certificate delivery, and 1099-R reporting.
- Do not roll the 401(k) into an IRA "to decide later." That single step eliminates NUA permanently.
