The lump-sum distribution rule: NUA's #1 disqualifier
Net Unrealized Appreciation (NUA) treatment — paying long-term capital-gains rates on the growth of employer stock instead of ordinary income rates — is only available if the stock comes out of the plan as part of a qualifying lump-sum distribution. Miss the lump-sum requirement and the NUA math never gets a chance to matter, no matter how good it looks on paper.
The rule sounds simple — “take everything out in one year” — but it has three moving parts, and one of them is routinely blown by accident, sometimes years before anyone starts thinking about NUA.
What counts as a qualifying lump-sum distribution
IRS Publication 575 defines a lump-sum distribution as “the distribution or payment of a plan participant's entire balance (within a single tax year) from all of the employer's qualified plans of one kind” — pension, profit-sharing, or stock bonus plans — paid after a triggering event. Unpack that and you get three tests, all of which must pass:
- ENTIRE balance. Everything credited to you must come out — the employer stock, the mutual funds, the cash, all of it. The account balance in the plan must be zero by December 31 of the distribution year.
- One tax year. The full payout must land within a single tax year. It does not have to be the year of the trigger, but it cannot straddle a January 1.
- All plans of one kind, combined. The employer's profit-sharing plans count as one plan, its pension plans as one, and its stock bonus plans as one. If the same employer has you in two profit-sharing plans, both must be emptied in the same year.
The non-stock portion doesn't have to be taxed to satisfy the rule — it can move by direct rollover to an IRA in the same year. What matters is that the plan balance goes to zero within the one tax year.
The four triggering events
A lump-sum distribution only qualifies if it is paid on account of one of four events listed in IRC 402(e)(4)(D):
- Separation from service — leaving the employer, voluntarily or not. This trigger applies only to common-law W-2 employees.
- Reaching age 59½ — available whether or not you are still working there.
- Death — the beneficiary can take a qualifying lump-sum distribution.
- Disability — but ONLY for self-employed participants (see the warning below).
The disability trigger is narrower than most articles say
Under IRC 402(e)(4)(D), the separation-from-service trigger applies only to common-law employees, and the disability trigger applies only to participants who are self-employed (employees within the meaning of section 401(c)(1)). If you are a W-2 employee who becomes disabled, disability itself does not create a lump-sum trigger for you — your path runs through separation from service, age 59½, or death. Plenty of otherwise-solid NUA articles list disability as a universal trigger. It isn't.
The silent voider: distributions after your trigger
Here is the part that disqualifies people years in advance. A distribution taken after a triggering event but beforethe year of your intended lump-sum distribution — an “intervening distribution” — generally uses up that trigger. Once the trigger is spent, emptying the account later no longer produces a qualifying lump-sum distribution based on that event.
The classic patterns: you leave the company at 56, take a “small” partial withdrawal at 57 to bridge a gap, and then try to do NUA at 58 — the separation trigger is spent. Or the plan pays out an automatic installment, or a required minimum distribution, in a year before your lump-sum year. None of these feel like decisions about NUA at the time. All of them can quietly close the door.
The door is not always locked forever: a new triggering event restarts eligibility. The most common reset is reaching age 59½ — after that new trigger, a clean full-balance distribution in one tax year (with no new intervening distributions) can qualify again. Before counting on any of this, ask the plan administrator, in writing, for your complete distribution history since your trigger event, and review it with your CPA.
The stock itself must move in-kind
Within the lump-sum distribution, the employer shares must be distributed as actual shares — transferred in-kind to a taxable brokerage account. Two moves permanently destroy NUA treatment for those shares: selling the stock inside the plan and taking cash, and rolling the shares into an IRA. Once employer stock lands in an IRA, every dollar of it is on the ordinary-income track for good; there is no undo. The rest of the account — the funds and cash — can and usually does go to an IRA by direct rollover in the same year without harming the election.
This is why the sequencing conversation with the plan administrator matters more than the math: one wrong checkbox on a distribution form converts an irreversible tax election into an irreversible tax mistake. Get the process in writing, and have your CPA review it before anything moves.

Common questions
Does the lump-sum year have to be the same year I left the company?
No. The one-tax-year clock applies to the distribution, not the trigger. You can separate from service and take the qualifying lump-sum distribution years later — as long as you took no distributions from the plan in between and the entire balance comes out within a single tax year. Confirm your distribution history with the plan administrator in writing before relying on this.
I took a partial withdrawal after separating. Is NUA gone for good?
Not necessarily forever. A distribution taken after a triggering event and before your lump-sum year generally spends that trigger, so a later full distribution no longer qualifies. But a NEW triggering event — most commonly reaching age 59½ — can restore eligibility, provided no distributions intervene between the new trigger and the lump-sum year. This is exactly the kind of fact pattern to walk through with your CPA before touching the account.
Do all of my accounts with this employer count toward the entire balance?
All plans of the same kind are aggregated. The tax code treats all of an employer's profit-sharing plans as one plan, all pension plans as one, and all stock bonus plans as one (IRC 402(e)(4)(D)(ii)). A 401(k) is typically a profit-sharing plan, so a forgotten second profit-sharing account with the same employer must also be emptied in the same tax year.
Does disability count as a lump-sum trigger?
Only for self-employed participants. Under IRC 402(e)(4)(D), disability is a triggering event solely for individuals who are employees within the meaning of section 401(c)(1) — the self-employed. A common-law W-2 employee who becomes disabled does not get a disability trigger; they must rely on separation from service, reaching 59½, or death. Many summaries get this wrong, so verify your own trigger with a CPA.
