How the NUA Strategy Works

When you take a lump-sum distribution of employer stock from your 401k, you pay ordinary income tax only on the cost basis β€” the price at which shares were allocated to your account. The Net Unrealized Appreciation (the gain from cost basis to current market value) is not taxed until you sell the stock, and then it is taxed at preferential long-term capital gains rates (0%, 15%, or 20%).

The alternative β€” rolling the stock to an IRA β€” defers all taxes, but when you eventually withdraw, 100% of the value (including all appreciation) is taxed as ordinary income. NUA wins when the capital gains rate differential is large enough to offset immediate tax on the basis.

The Formula

NUA = (FMV βˆ’ Cost Basis) Γ— Shares
NUA Tax on Basis = Ordinary tax on (Cost Basis Γ— Shares + Other Income)
NUA Tax on Appreciation = NUA Amount Γ— LTCG Rate (0/15/20%)
IRA Tax = Ordinary tax on (FMV Γ— Shares + Other Income when withdrawn)
Savings = IRA Tax βˆ’ (NUA Basis Tax + NUA Appreciation Tax)

Example

1,000 shares, cost basis $20/share, FMV $85/share, $40K other income (single):
NUA Amount: ($85 βˆ’ $20) Γ— 1,000 = $65,000
Basis taxed at ordinary rates: $20,000 β†’ ~$2,200 tax
NUA appreciation: $65,000 Γ— 15% LTCG = $9,750
NUA total tax: $11,950 | Effective rate: 14.1%
IRA rollover: $85,000 all at ordinary rates β†’ ~$18,700 tax | Effective rate: 22%
NUA saves $6,750 β€” strategy wins!

FMV Sensitivity Analysis

See how NUA tax savings change at different stock price levels β€” from $50 to $1,000 per share

How does NUA savings change as the stock price increases? The NUA advantage grows with more appreciation because the appreciation is always taxed at capital gains rates instead of ordinary rates.

Frequently Asked Questions

What is Net Unrealized Appreciation (NUA)?
NUA is the difference between the fair market value (FMV) of employer stock in your 401k and the original cost basis you paid for it. When you take a lump-sum distribution of employer stock, only the cost basis is taxed as ordinary income. The NUA portion is then taxed at lower long-term capital gains rates when you eventually sell the stock β€” which can result in significant tax savings.
What qualifies as an NUA distribution?
To use the NUA strategy, you must take a lump-sum distribution β€” meaning you must distribute your entire 401k balance in a single tax year triggered by a qualifying event: reaching age 59Β½, separating from service, disability, or death. Partial distributions do not qualify. You must receive the actual employer stock shares, not cash.
Is the 10% early withdrawal penalty waived for NUA?
The 10% early withdrawal penalty applies to the cost basis portion of the NUA distribution if you are under age 59Β½ and do not meet another exception (such as separation from service at age 55 or older). The NUA portion itself is not subject to the penalty β€” it is only taxed as capital gains when you sell the stock.
Should I roll the employer stock to an IRA or use NUA?
NUA is most advantageous when: (1) you have a low cost basis relative to current FMV (large appreciation), (2) you are in a high ordinary income tax bracket but would pay 15% or 20% LTCG rates, or (3) you plan to sell the stock relatively soon. IRA rollover is better when the appreciation is small, you expect lower ordinary rates in retirement, or you want to continue deferring taxes.
Can I do a partial NUA β€” keep some stock in the plan and roll the rest?
No. NUA requires a complete lump-sum distribution of your entire plan balance in one tax year. However, you can direct different portions to different destinations: roll the non-employer-stock portion (bonds, mutual funds) to an IRA for continued tax deferral, while taking the employer stock shares in-kind to use the NUA strategy.
