The NUA Move That Cuts a Retiring Executive’s Tax on $480,000 of Employer Stock From 32% to 15%

Picture a 62-year-old Apple lifer cleaning out an office for the last time. The 401(k) statement shows $1.9 million, with $620,000 sitting in company stock accumulated over 25 years of ESPP purchases and employer match-in-stock. The cost basis on those shares is $140,000. The default move, rolling the entire balance to an IRA, looks clean. It also leaves roughly $60,000 to $80,000 in federal tax on the table.

That gap is the Net Unrealized Appreciation election under IRC §402(e)(4), and for an executive sitting on low-basis employer stock it is the single mechanic that reshapes the retirement tax bill.

Why the IRA rollover quietly costs six figures

Roll the full balance into an IRA and every future dollar comes out as ordinary income. The 2026 brackets put the 32% rate on single income above $201,775 and joint income above $403,550, so the $480,000 of embedded gain on the employer stock eventually clears the IRA somewhere in the 24% to 32% range through withdrawals and RMDs. That works out to roughly $130,000 to $155,000 in federal tax on the appreciation alone over the retirement horizon.

For a sense of the appreciation profile that creates this trap, Apple (NASDAQ:AAPL | AAPL Price Prediction) trades near $312 today, up 57% over the past year and 1,273% over the past decade. Decades of compounded gains, all sitting at ordinary-income rates inside the wrapper, is exactly the situation NUA was written for.

The NUA move in dollar terms

The alternative: take a qualifying lump-sum distribution of the entire 401(k) in a single calendar year and move the employer shares in-kind into a taxable brokerage account. The $140,000 cost basis hits the W-2 as ordinary income in the distribution year, costing roughly $45,000 at 32%. The $480,000 of appreciation lands in the taxable account untaxed until the shares are sold, and when they are sold it is at long-term capital gains rates of 15% or 20%, with no holding-period requirement on the original NUA portion.

Sell every share the morning after at the 15% rate and federal tax on the appreciation is $72,000. At 20% it tops out near $96,000. The executive saves between $60,000 and $80,000 versus the IRA path, and the gap widens the longer the sale is deferred.

Heirs sharpen the math further. NUA shares left at death receive a step-up in basis on any post-distribution appreciation, wiping out capital-gains tax on that growth entirely for the next generation.

Four conditions that kill the election

The rules under §402(e)(4)(D) and IRS Publication 575 are unforgiving. Miss one and the strategy collapses into a normal taxable distribution.

1. Lump-sum distribution. The entire 401(k) balance must leave the plan within one calendar year. Non-stock assets roll to an IRA; the employer shares go in-kind to a taxable brokerage. A partial distribution in a prior year disqualifies what remains.
2. Triggering event. Separation from service, reaching 59½, death, or disability. A 62-year-old retiring executive satisfies both of the first two, which is the cleanest possible setup.
3. Correct 1099-R coding. The plan administrator must report cost basis in Box 2a and NUA in Box 6. Miscoded forms cause the IRS to treat the entire fair market value as taxable ordinary income.
4. Partial NUA on the right lots. High-basis shares offer little benefit. Roll those into the IRA and reserve NUA treatment for the oldest, lowest-basis lots where the appreciation spread is widest.

What to do this quarter

Pull a cost-basis report from the plan administrator broken out by tax lot before signing any separation paperwork. Identify which lots are NUA-worthy and which are not. Then map a diversification glide path: with the 10-year Treasury at 4.45%, trimming the concentrated position into a laddered bond and broad-equity mix over two to three years earns a real opportunity-cost return while spreading capital-gains recognition across tax years. Get the NUA election in writing with the administrator before the distribution. The IRS does not allow retroactive recharacterization, and a miscoded 1099-R is the most common way this strategy quietly fails.
