When does NUA make sense?

NUA is most valuable when three conditions overlap: (1) your employer stock has risen a lot in value (NUA is large relative to cost basis), (2) your ordinary income tax rate is well above your long-term capital gains rate, and (3) you have a triggering event: separation from service (employees), reaching 59 1/2, death, or disability (self-employed people only). If the NUA is small or your rate differential is narrow, rolling to an IRA and paying ordinary rates may produce a similar result.

What are the NUA triggering events?

The NUA distribution must be a lump sum distribution triggered by a qualifying event: separation from service for employees (quitting, firing, layoff), reaching age 59 1/2, death, or disability for self-employed people. The entire balance of the plan (all of the employer's plans of the same type, such as all its profit-sharing plans, count as one) must be distributed in a single tax year. Rolling the non-stock assets to an IRA counts as distributing them. Partial distributions do not qualify. You cannot cherry-pick the employer stock while leaving other funds in the plan.

Does the 10% early withdrawal penalty apply to NUA?

The 10% penalty applies to the cost basis portion of the distribution if you are under age 59 1/2 and the triggering event is not an exception. The NUA itself isn't subject to the 10% penalty because it isn't taxed at distribution; it's taxed as long-term capital gain when you sell. No penalty applies if you left this employer in or after the year you turned 55 (50 for qualified public safety employees in a governmental plan), under IRC 72(t)(2)(A)(v).

Can I use NUA for stock I bought in the 401(k) myself?

NUA applies only to employer stock: shares of the company you worked for that were contributed by the employer or purchased within the plan. If you directed your own 401(k) contributions to buy your employer's publicly traded stock, that stock may qualify, but the treatment depends on how the plan tracks cost basis. Self-directed purchases of employer stock inside a 401(k) can qualify, but verify your cost basis records with your plan administrator.

NUA Calculator: Employer Stock Tax Strategy

Q: What is the NUA strategy?

Net Unrealized Appreciation (NUA) is a provision under IRC § 402(e)(4) that lets you take employer stock out of your 401(k) as an in-kind distribution instead of rolling it to an IRA. You pay ordinary income tax only on your cost basis (what the employer paid for the shares). When you eventually sell, the appreciation (the NUA) is taxed at long-term capital gains rates, not ordinary income rates. This can save a lot of tax when the NUA is large and your ordinary rate is high.

If your 401(k) holds employer stock that has risen a lot in value, rolling it to an IRA may not be the best move. The NUA strategy under IRC § 402(e)(4) lets you pay long-term capital gains rates on the appreciation instead of ordinary income rates. Calculate whether it saves you money.

How this calculator works and the math behind it

If your 401(k) holds employer stock, the NUA strategy (IRC § 402(e)(4)) may let you pay ordinary income tax only on the cost basis when you take a lump-sum distribution, then long-term capital gains on the remaining appreciation when you sell.

Important: NUA eligibility requires a complete lump-sum distribution. If you take a partial distribution, moving only the employer stock while leaving other funds in the plan, you lose NUA treatment on the shares bought with employer money (IRC 402(e)(4)). The entire balance of the plan (all of the employer\'s plans of the same type count as one) must be distributed within one tax year. Confirm your cost basis with your plan administrator before the distribution. The 10% early withdrawal penalty applies to the cost basis portion if you are under 59 1/2 and don\'t qualify for an exception, such as leaving this employer in or after the year you turned 55. This calculator provides tax estimates for planning purposes. Before executing an NUA distribution, verify your eligibility, triggering event, cost basis, and tax consequences with a qualified tax professional. Terms of use.

How the NUA calculation works

Say your employer contributed stock with a cost basis of $20,000, and it's now worth $150,000. The NUA is $130,000. If you roll everything to an IRA and withdraw later, all $150,000 comes out at your ordinary income rate. At 32%, that's $48,000 in federal tax.

With NUA, you take the stock as an in-kind distribution. You pay ordinary income tax on the $20,000 basis immediately: $6,400 at 32%. When you sell the shares, the $130,000 NUA is taxed as long-term capital gains at 0%, 15% or 20% depending on your income. At 15%, that's $19,500. Total tax: $25,900 instead of $48,000. Savings: $22,100.

The strategy works best with a low cost basis relative to market value and a wide gap between your ordinary and capital gains rates. Holding the shares for years after distribution doesn't cost you the NUA treatment, but dividends in a taxable account are taxed every year and one company's stock is a concentrated bet.

One catch: the entire plan balance must be distributed in the same tax year. You cannot move just the stock and leave the mutual funds in the plan. This means you may also be triggering a taxable event on cash and other positions unless you roll them to an IRA at the same time. The usual setup is a split distribution: roll everything except the employer stock to an IRA and take the employer stock in-kind.

Frequently asked questions

What is the NUA strategy?

Instead of rolling employer 401(k) stock to an IRA, you take it as an in-kind distribution. Pay ordinary income tax only on the cost basis now. When you sell, the appreciation (the NUA) is taxed at long-term capital gains rates (0%, 15% or 20%) instead of ordinary rates that run up to 37%. The bigger the NUA, the bigger the gap.

When is NUA worth using?

When the NUA is large relative to your basis, your ordinary rate is well above your capital gains rate, and you have a qualifying distribution event. A small NUA or narrow rate differential reduces the advantage to near zero.

What triggers qualify?

Separation from service (employees), reaching 59 1/2, death, or disability (self-employed only). The full plan balance (not just the stock) must be distributed in one tax year, though the non-stock part can be rolled to an IRA. Partial distributions don't qualify.

Does the 10% penalty apply?

On the cost basis portion, yes, if you're under 59 1/2 and don't have an exception. The NUA itself isn't taxed or penalized at distribution; it's taxed as capital gain when sold. Leaving this employer in or after the year you turn 55 (50 for qualified public safety employees) also avoids the penalty.

Should I hold the stock after distribution?

Depends. The NUA keeps long-term treatment whenever you sell. Appreciation after the distribution date is short-term or long-term depending on how long you hold the shares after distribution, and unlike the NUA it counts toward the 3.8% net investment income tax.
