NUA Pre-Retirement Planning: A 1-to-5-Year Checklist

Short answer: The NUA election is made once — at your qualifying event (typically separation from service at retirement). But the decisions that determine whether NUA saves you $50,000 or $300,000 happen years before that moment: finding your cost basis, shaping your income in the distribution year, checking your plan rules, and coordinating NUA with Roth conversions and Social Security claiming. This guide covers what to do at each stage.

Why planning ahead changes the outcome

The most common NUA failure mode isn't a bad plan — it's a missed opportunity. A generalist advisor, unaware of the NUA election or simply defaulting to rollover paperwork, processes the 401(k) distribution to an IRA the day after retirement. The employer stock moves to the IRA. The NUA opportunity is permanently destroyed. This happens routinely, and it costs the retiree $100,000–$300,000 of lifetime tax on a significant employer stock position.

Planning 1–5 years ahead changes the outcome because:

You can verify the NUA math before you sign any rollover paperwork
You can shape income in your distribution year to minimize bracket friction
You can avoid an IRMAA spike two years after the NUA year — if you anticipate it in advance
You can confirm your plan allows in-kind distribution while there is still time to push back if it doesn't
You can sequence NUA with Roth conversions and Social Security claiming for the maximum after-tax result

The one-shot rule: NUA is available once per qualifying event per plan. Once employer stock enters an IRA — even accidentally — the NUA opportunity on those shares is permanently gone. There is no corrective distribution, no IRS procedure to undo it. Planning ahead is the only protection.

Step 1: Find your plan cost basis now

The most important number in any NUA analysis is your plan cost basis — the IRS-recognized average cost of the employer securities as they were contributed to the plan over time. This is different from the current market value and different from what typically appears on your brokerage statement. It is a plan-level accounting figure the 401(k) administrator is required to maintain under Rev. Rul. 81-122.

How to request it

Your plan cost basis lives with the plan's custodian (Fidelity, Vanguard, Schwab, Empower, etc.) or the plan administrator. Here is how to request it:

Call or write the 401(k) custodian. Ask for your "employer stock plan cost basis" or "IRC §402(e)(4) cost basis." Front-line customer service agents may not recognize these terms — ask to speak with a retirement plan tax specialist or benefits administrator.
Check your annual statement. Some custodians show "plan cost" or "cost of employer securities" on the year-end statement. Look for the figure associated specifically with the employer stock fund, not the total account value.
Contact HR or the plan sponsor. Your company's HR or benefits department can route the request to the plan administrator. Frame it as: "I need the IRS plan cost basis of my employer stock for NUA planning purposes."

What you are looking for: a dollar amount representing the total cost of the employer shares in your account, accumulated over years of company match contributions, profit-sharing allocations, and any direct stock purchases made inside the plan.

Why the basis amount matters so much

Scenario	Stock value	Plan cost basis	Appreciation ratio	Approximate NUA savings vs. rollover
Low appreciation	$500K	$200K	2.5×	~$30K–$55K (marginal; depends on state)
Moderate appreciation	$500K	$100K	5×	~$80K–$120K (NUA clearly wins in most scenarios)
High appreciation	$500K	$50K	10×	~$130K–$175K
Very high appreciation	$500K	$25K	20×	~$155K–$210K

Illustrative. Actual savings depend on your marginal brackets, state LTCG treatment, holding period after distribution, and NIIT exposure. Use the NUA vs. Rollover Calculator for your specific numbers.

If your appreciation ratio is below 2×, NUA is borderline in most scenarios. Above 4×, NUA wins in almost all scenarios. If you do not know your basis, you cannot place yourself on this table — and you are flying blind into an irreversible decision.

Step 2: Model NUA savings at different retirement dates

Once you have your cost basis, build a projection: if the stock grows at a conservative annual rate, what is the appreciation ratio in 1, 2, 3, and 5 years? Does the NUA math improve significantly over time?

The key insight: as the stock price grows, NUA becomes more valuable. The cost basis stays fixed, but the NUA appreciation layer — which becomes long-term capital gains — grows with the stock price. The ordinary income hit in the distribution year (the cost basis) stays the same, while the LTCG savings compound upward.

In many situations, a retiree with a 4× ratio today who waits two years for the ratio to reach 7× captures substantially more lifetime value from NUA. Use the NUA vs. Rollover Tax Calculator to model multiple retirement dates by adjusting the stock value input.

One caution: don't delay retirement just for NUA

If you are otherwise ready to retire, delaying retirement solely to improve the NUA ratio is usually not worth it. The incremental NUA savings from a higher stock price rarely outweigh the income, flexibility, and personal value of retiring when you want to. Model the numbers, but let retirement timing be driven by your life plan.

Step 3: Manage your income in the NUA distribution year

The NUA election creates one unavoidable tax event in the distribution year: ordinary income equal to your plan cost basis. If your basis is $100,000, you owe ordinary income tax on $100,000 the year you take the in-kind distribution — regardless of whether you sell the stock or hold it.

What lands on top of that cost basis in the same year determines how much you pay. Common income sources in the retirement year:

Partial-year W-2 wages (if you retire mid-year)
Severance packages
Nonqualified deferred compensation distributions
Pension income starting immediately at retirement
Social Security income (if you claim that year)
Required minimum distributions from other IRAs or retirement accounts
Capital gains from other taxable account sales

The higher your total income in the NUA year, the higher the marginal rate on that cost basis. Pre-retirement planning gives you time to reduce the stacking:

Defer nonqualified deferred compensation. If you have an NQDC plan, coordinate the distribution schedule with your plan administrator. Taking a large NQDC distribution in the same year as NUA stacks ordinary income — consider deferring to the year after NUA.
Do not claim Social Security in the NUA year. Social Security benefits become up to 85% taxable if your provisional income exceeds $34,000 (single) / $44,000 (MFJ).¹ The NUA cost basis distribution counts as provisional income. Delaying SS by one year avoids stacking. See our NUA and Social Security guide.
Do not run large Roth conversions in the NUA year. The cost basis spike is already an ordinary income event. Roth conversions are ordinary income too. Sequencing them in the following year — when your income is lower — almost always produces a better combined outcome. See our NUA and Roth Conversion guide.

2026 long-term capital gains rate thresholds

If you plan to sell some NUA stock in the same year as the distribution, the NUA appreciation is taxed as long-term capital gains:²

Rate	Single — taxable income	Married filing jointly
0%	Up to $48,350	Up to $98,900
15%	$48,350–$533,400	$98,900–$600,050
20%	Above $533,400	Above $600,050
20% + 3.8% NIIT	MAGI above $200,000	MAGI above $250,000

2026 LTCG thresholds per IRS Rev. Proc. 2025-32. NIIT thresholds ($200K/$250K) are not inflation-adjusted. See our NUA and NIIT guide.

Practical implication: if your total income in the NUA year will keep you in the 15% LTCG bracket, selling the NUA stock in the same year is tax-efficient. If selling would push you into the 20% + NIIT zone, tranche selling over several years is almost always better.

Step 4: Plan for the IRMAA two-year look-back

Medicare uses a two-year income look-back: your 2026 Part B premium is based on your 2024 MAGI. This means the income spike in your NUA distribution year will trigger higher Medicare premiums exactly two years later.³

For 2026, IRMAA surcharges begin at $109,000 MAGI (single) / $218,000 (MFJ), based on 2024 income. If your NUA distribution year pushes total MAGI above that threshold, you face Part B surcharges two years afterward — on top of the base premium of $202.90/month.

Planning example: A retiree who does NUA in 2027 with $80,000 of cost basis income on top of $60,000 in other income has $140,000 of ordinary income that year. That pushes 2029 Medicare Part B premiums into the first IRMAA tier. Pre-retirement planning — deferring Social Security to 2028, controlling deferred comp timing — could keep 2027 total ordinary income below $109,000 and avoid the surcharge entirely.

The SSA Form SSA-44 (Life-Changing Event appeal) provides some protection after the fact: if the income spike was a one-time event due to retirement, you can appeal the IRMAA surcharge. But the SSA-44 process requires filing and adjudication — it is better avoided than corrected retroactively.

For the full tier table, tranche-selling strategies to reduce LTCG below IRMAA thresholds in post-NUA years, and the SSA-44 process, see our NUA and IRMAA guide.

Step 5: Verify your plan allows in-kind distribution

NUA requires the employer stock to be distributed in kind — the actual shares transfer to your taxable brokerage account. If the plan sells the stock and sends cash, NUA is not available. If the plan requires all distributions in cash, NUA is not available.

Not every 401(k) plan allows in-kind distribution. Before assuming NUA is possible, verify:

Read the Summary Plan Description (SPD). The SPD is a plain-language document your employer is required to provide upon request. Look for sections on "distribution" or "employer securities." Language allowing "distribution of employer securities in-kind" or "employer stock in non-cash form" confirms the option is available.
Check the plan document itself. The SPD is a summary; the full plan document governs. If the SPD is ambiguous, request the plan document from HR. Alternatively, contact the plan's trustee directly.
Ask HR directly. Frame the question precisely: "Does the plan permit an in-kind distribution of employer stock to a taxable brokerage account at retirement?" Get the answer in writing.

What if your plan doesn't allow in-kind distribution? Plan amendments require board approval and typically take 6–18 months. If you are 4+ years from retirement, there may be time to advocate for a plan amendment through HR. If you are retiring in 6 months, the plan document likely cannot be changed in time. Knowing this early is what makes pre-retirement planning valuable.

Special case — ESOPs: Closely held employer stock ownership plans often restrict or prohibit in-kind distributions. See our NUA for ESOP Participants guide for plan-type-specific rules, including put option mechanics under IRC §409(h).

Step 6: Stock price timing and the appreciation ratio

In theory, a higher stock price means a higher appreciation ratio, which means more NUA value. In practice, timing the stock market is not a reliable strategy — and the appreciation ratio is rarely the most important variable once you are above 4×.

What actually moves the needle most:

The appreciation ratio at distribution. 2× is marginal in most scenarios; 4× is solid; 8× or higher means NUA wins across virtually all bracket and state combinations. See our When NUA Wins vs. Loses guide for the full scenario analysis.
Your state's LTCG treatment. California, New York, New Jersey, and Oregon tax capital gains as ordinary income at the state level — eliminating the state-level NUA spread entirely. Federal NUA savings are still real, but the combined net savings are smaller. See our NUA and State Taxes guide.
Your investment horizon after distribution. If you plan to hold the NUA stock for 10+ years, the estate planning dimension (post-distribution appreciation receives a step-up at death; the NUA layer does not) can increase or decrease the total NUA advantage depending on your estate situation. See our NUA and Estate Planning guide.

Practical guidance: if you are already at a high appreciation ratio (8×+), the NUA math wins across virtually all reasonable stock price scenarios. Do not wait in "hoping for a higher stock price" when you are already at a compelling ratio. Model the downside — if the stock dropped 30–40% from here, would NUA still beat rollover? For most high-ratio positions, yes.

Step 7: Coordinate NUA with other major retirement moves

NUA does not happen in isolation. Pre-retirement planning should map the NUA decision against these other retirement moves:

Roth conversions

The most common sequencing mistake: doing NUA and a large Roth conversion in the same year. Both create taxable ordinary income — the NUA cost basis and the Roth conversion amount stack directly. The better path: take the NUA distribution first (the cost basis hit is unavoidable and fixed), then begin Roth conversions in lower-income subsequent years when your pre-tax IRA balance is also reduced by the NUA amount. See our NUA and Roth Conversion sequencing guide.

Social Security claiming

The NUA cost basis distribution counts as ordinary income in the IRC §86 provisional income calculation that determines how much of your Social Security is federally taxable. Claiming SS in the same year as NUA can push 85% of your SS benefit into taxable income, compounding the cost basis hit. In most scenarios, delaying SS claiming by one year is preferable — take the NUA distribution first, start SS the following year. See our NUA and Social Security guide.

Required minimum distributions

NUA permanently reduces your pre-tax plan balance — removing employer stock from the 401(k) shrinks the balance that will eventually be subject to RMDs at age 73 or 75 under SECURE 2.0.⁴ If you are planning NUA 5 years before retirement, model your future RMD obligation under both the NUA and full-rollover scenarios. The NUA path systematically reduces forced ordinary income at age 73+. See our NUA and RMD guide.

Beneficiary designations

Before executing NUA, review beneficiary designations on your 401(k). Post-NUA, the employer stock moves to a taxable brokerage account — which has different estate treatment than a retirement account. Update TOD (transfer-on-death) designations on the receiving brokerage account to match your estate plan. NUA changes the character of the asset from pre-tax plan to taxable brokerage, and your estate documents should reflect that. See our NUA and Estate Planning guide.

The 15-point NUA pre-retirement checklist

1–5 Years Out

Request your employer stock plan cost basis from the 401(k) custodian (ask specifically for "IRC §402(e)(4) plan cost basis")
Calculate your current appreciation ratio: current employer stock value ÷ plan cost basis
Run the NUA vs. rollover model at current and projected appreciation ratios for multiple retirement dates — use the NUA vs. Rollover Calculator
Read your Summary Plan Description to confirm the plan allows in-kind distribution of employer stock at separation from service
Identify your qualifying event type (separation from service? In-service distribution at 59½? Both available?)
Check whether your state taxes long-term capital gains as ordinary income — this materially affects the NUA value proposition

2 Years Out

Map all income sources in the planned NUA distribution year: partial-year wages, severance, deferred comp, pension, Social Security, rental income, other IRA distributions
Project whether NUA distribution-year MAGI will trigger IRMAA surcharges two years later (threshold: $109,000 single / $218,000 MFJ for 2026 IRMAA based on 2024 income)³
Decide Roth conversion timing relative to NUA year — typically: NUA year first, Roth conversions in subsequent years
Decide Social Security claiming timing relative to NUA year — typically: NUA distribution first, SS starts the following year
Notify your 401(k) custodian and HR that you plan to take an in-kind distribution of employer stock at separation from service

6 Months Out

Confirm the in-kind distribution process with the custodian: get the exact form name, receiving account instructions, and transfer timeline (some custodians require 4–6 weeks)
Open a taxable brokerage account to receive the in-kind employer stock transfer if you do not already have one set up
Obtain written confirmation of your plan cost basis from the custodian — this number goes on Schedule D
Decide whether to elect full NUA (all employer stock) or partial NUA (high-appreciation lots only) — see our Partial NUA Strategy guide

Final item: Engage a fee-only NUA advisor before your qualifying event. A specialist integrates your full retirement income picture — income sequencing, Roth conversion runway, state taxes, IRMAA exposure, and estate step-up mechanics — into a single NUA go/no-go recommendation with lifetime tax projections. This one-shot decision affects 20–30 years of your tax picture. See our guide to finding a fee-only NUA advisor.
