Which Retirement Plans Qualify for NUA? The Complete Plan-Type Eligibility Guide

Short answer: NUA applies only to distributions from §401(a) qualified plans — primarily 401(k), profit-sharing, and ESOP plans. 403(b) plans, 457(b) plans, TSP, SIMPLE IRA, and SEP IRA do not qualify. IRS Notice 2002-3 makes this explicit.

The statutory basis: why plan type matters

The NUA election lives in IRC § 402(e)(4). The provision grants favorable LTCG treatment to the appreciation inside employer stock when that stock is distributed as part of a "lump-sum distribution" — defined in § 402(e)(4)(D) as a distribution from "a trust which forms a part of a plan described in section 401(a)."¹

That phrase — "plan described in section 401(a)" — is the gating language. If your plan isn't a §401(a) qualified plan, the NUA provision doesn't reach it, regardless of how much appreciated employer stock you hold inside it.

The core rule: NUA is only available for distributions from §401(a) qualified plans. Whether a specific plan type qualifies comes down to whether it's organized under §401(a) — not whether it's tax-deferred, employer-sponsored, or holds employer stock.

Plans that DO qualify for NUA

Plan Type	NUA Eligible	Notes
401(k) plan	Yes	Most common NUA scenario. Must hold actual employer stock, not just an employer stock fund.
Profit-sharing plan	Yes	§401(a) qualified plan; NUA applies if employer stock held.
ESOP (Employee Stock Ownership Plan)	Yes	Often the largest NUA opportunity — decades of contributions at very low basis. Closely held ESOPs have in-kind distribution restrictions; verify plan document.
Money purchase pension plan	Yes	§401(a) qualified plan. Rarely holds employer stock in practice.
Defined benefit/pension plan	Technically yes	DB plans are §401(a) trusts, but they almost never hold separable lots of employer stock that can be distributed in-kind. Practically unavailable in most DB plans.

Plans that do NOT qualify for NUA

Plan Type	NUA Eligible	Why Not
403(b) plan	No	403(b) plans are tax-sheltered annuities under §403(b) — not §401(a) trusts. IRS Notice 2002-3 explicitly confirms NUA is unavailable.
457(b) governmental plan	No	§457(b) deferred compensation plans are not §401(a) trusts. IRS Notice 2002-3 explicitly excludes them. Also: they typically don't hold individual employer stock.
457(f) nonqualified deferred comp	No	Not a §401(a) plan; distributions are fully ordinary income.
TSP (Thrift Savings Plan)	No	Federal government plan under 5 U.S.C. §8437. Not a §401(a) plan. Additionally, TSP doesn't hold individual employer stock — funds are government-managed investment vehicles.
SIMPLE IRA	No	IRA-based plan. IRAs are not §401(a) qualified trusts.
SEP IRA	No	IRA-based plan. IRAs are not §401(a) qualified trusts.
Traditional IRA / Rollover IRA	No	IRAs are not §401(a) trusts. If you already rolled 401(k) funds to an IRA, the NUA election is permanently lost on those funds.
Roth IRA	No	IRA-based; distributions already tax-free, so NUA provides no additional benefit.

The 403(b) case: the most common question, the clear answer

Teachers, hospital employees, university staff, and employees of non-profit organizations frequently ask whether they can use NUA on company stock in their 403(b). The answer is no, and the reason is statutory: 403(b) plans are "tax-sheltered annuity" contracts governed by IRC § 403(b) — a completely separate code section from the §401(a) qualified trust framework that NUA requires.²

IRS Notice 2002-3, which clarifies the rules for after-tax contributions in retirement plans, explicitly confirms that the NUA provisions of § 402(e)(4) are not available for 403(b) distributions.³

Additionally: 403(b) plans rarely hold individual employer stock at all. Most 403(b) plans invest through annuity contracts or mutual fund custodial accounts — they don't offer employer stock as an investment option (you can't buy hospital stock in your 403(b) even if you wanted to). So even if the law permitted NUA from 403(b) plans, the prerequisite — a meaningful position in employer stock — is almost never present.

What 403(b) participants CAN do

If you work for an institution that also sponsors a 401(a) money purchase pension plan (common for government employees and some universities), and that plan holds employer stock, that plan would be eligible for NUA even though your 403(b) isn't. Check your benefits package — some employers offer both plan types.

For most 403(b) participants, the strategy conversation shifts to Roth conversions, RMD optimization, and charitable strategies — not NUA, which simply doesn't apply.

The IRA rollover trap that permanently destroys NUA eligibility

One of the most costly mistakes in retirement planning: an employee with $800K of low-basis employer stock in their 401(k) rolls everything — including the stock — into a traditional IRA. The NUA election is now permanently gone for those assets. Once employer stock enters an IRA, it becomes ordinary income upon withdrawal, indistinguishable from any other IRA asset.

The election must happen at the plan level, during a qualifying distribution from the §401(a) plan. You cannot elect NUA retroactively after a rollover, and you cannot un-ring the bell once the assets are in an IRA.¹

Practical consequence: If you're retiring and have a brokerage account saying "roll over your 401(k)" — stop. Before moving anything, check whether your 401(k) holds employer stock with a low cost basis. If it does, get an NUA analysis first. A 15-minute review could be worth six figures.

The same applies to in-plan Roth conversions: converting employer stock inside the plan to Roth 401(k) changes its tax treatment and may complicate or eliminate the NUA election. This should be modeled before any conversions that affect the employer stock lot.

If you have both a 401(k) and a 403(b)

This is a common situation for employees at universities, hospitals, and large non-profits that offer both plan types. The NUA analysis applies exclusively to the 401(k) side:

Check which plan holds employer stock. If your employer's stock is only available in the 401(k), the NUA election comes from there. The 403(b) is irrelevant to the NUA decision.
The lump-sum distribution requirement applies separately to each plan type. You need to distribute the entire balance from all §401(a) plans of the same type in the same tax year. Your 403(b) is a different plan type and doesn't factor into the 401(k) lump-sum calculation.¹
Don't let the 403(b) rollover timing interfere. Rolling your 403(b) to an IRA in the same year you're doing an NUA distribution from your 401(k) is fine — they're separate plan types with separate mechanics. The IRA rollover from 403(b) doesn't affect your 401(k) NUA election.

The practical sequence for someone leaving a job with both plans: execute the NUA distribution from the 401(k) (employer stock in-kind to taxable account, remainder rolled to IRA), then separately roll the 403(b) to IRA. Both happen cleanly in the same separation year.
