Layoff Income Spike 2026: Cut Tax on a $400K RSU + Comp Year

The decision: Priya’s $580K layoff year

Priya is a single filer in Austin, Texas, earning a $180,000 base salary as a senior product manager. In March 2026 her company is acquired and she’s laid off. Three things hit her tax return in the same year:

• $180,000 in partial-year wages for the months she worked, plus a severance package.
• $250,000 of accelerated RSU value — the change-in-control provision triggered the second leg of her double-trigger grant, vesting everything at once.
• $150,000 deferred-comp lump sum — her nonqualified 409A plan requires payout within 90 days of separation, so she can’t leave it parked.

Combined ordinary income: roughly $580,000. In a normal year Priya tops out in the 32% bracket. This year she crosses into the 35% bracket (single, income from $250,526 to $626,350 in 2026) and sits just under the 37% edge at $626,351. The question isn’t whether she owes a lot — she does. The question is how much of that $580K she can pull back out of the top brackets. The answer, with four levers stacked, is about $60,000 of income, worth roughly $21,000 in federal tax.

Why both payouts are ordinary income — not capital gains

The single most expensive misconception in a stacking year is assuming RSUs or deferred comp get capital-gains rates. They don’t.

RSU vesting is W-2 wage income. When restricted stock units vest, the fair market value of the shares on the vest date is ordinary compensation — reported on your W-2, subject to income tax, Social Security (up to the $181,800 wage base in 2026), and Medicare. Priya’s $250,000 of vesting shares is $250,000 of ordinary income. Only the gain after the vest date, if she holds the shares, becomes a capital gain.

Deferred comp under IRC §409A is also ordinary income. A nonqualified deferred compensation payout is taxed as wages when distributed. There is no preferential rate. Priya’s $150,000 lump sum is $150,000 of ordinary income on top of everything else.

Because it’s all ordinary income, it stacks at the graduated rates — there is no separate “bucket” and no order-of-operations trick that changes the total. The whole pile fills the brackets from the bottom up.

What the stack looks like in the 2026 brackets

Source: IRS Rev. Proc. 2025-32 (2026 inflation adjustments). Priya lives in Texas, so there’s no state income tax to layer on — if she lived in California, the top 13.3% state rate would add roughly $44,000 to the bill on the portion above the state’s top threshold. The federal supplemental withholding on her RSUs and 409A payout is a flat 22% (37% on any portion over $1M, IRS Pub. 15), which is far below her real 35% marginal rate. That gap means she should expect a large balance due at filing — and should set aside cash now rather than be surprised in April.

Lever 1: Max deductible retirement before year-end

Every pre-tax dollar you defer in 2026 comes off the top of the 35% bracket — a 35-cent federal saving per dollar. If Priya still has access to her employer 401(k) through her separation date, she should front-load deferrals from her final paychecks up to the $24,500 employee limit (IRC §402(g)); at 50+ the catch-up adds $8,000 for a $32,500 total.

The bigger opportunity is on the other side of the layoff. If Priya starts consulting — common after a senior-level layoff — a Solo 401(k) or SEP-IRA lets her shelter far more: up to $72,000 total (employee + employer, IRC §415(c)) in a Solo 401(k). Self-employment income in the same calendar year can absorb a meaningful slice of the spike. Maxing the standard 401(k) alone at her 35% rate is about $8,575 in federal tax saved.

Lever 2: Fund a family HSA

If Priya elects an HSA-eligible high-deductible health plan — through COBRA continuation or a marketplace plan after the layoff — she can contribute to a Health Savings Account. The 2026 limits are $4,400 self-only and $8,750 family (IRC §223(b)), plus a $1,000 catch-up at age 55+. HSA contributions are above-the-line deductions, so they reduce AGI even if she doesn’t itemize, and they triple-qualify: deductible going in, tax-free growth, tax-free for medical withdrawals. A family HSA contribution in the 35% bracket saves about $3,060 in federal tax.

Lever 3: Charitable bunching through a donor-advised fund

A spike year is the single best time to make charitable gifts, because the deduction is worth more at 35% than it will ever be in a normal 24% year. Rather than dribble out annual gifts, Priya can bunch two or three years of intended giving into one large lump sum to a donor-advised fund (DAF) in 2026, take the full itemized deduction now, and grant the money to charities over the following years.

The move that compounds the benefit: fund the DAF with appreciated stock rather than cash. She gets the fair-market-value deduction and avoids the capital-gains tax she’d owe if she sold the shares herself. For appreciated securities the deduction is capped at 30% of AGI; cash gifts are capped at 60% (IRC §170(b)), with a five-year carryforward for the excess. A $50,000 DAF gift in the 35% bracket is worth $17,500 in federal tax saved — the largest single lever on this list.

Lever 4: Harvest capital losses — and avoid the NIIT trap

Here is the lever that most people get backwards. In a year your MAGI is already $580K, you are far above the $200,000 single NIIT threshold (IRC §1411). That means any investment income you realize — dividends, interest, capital gains — gets an extra 3.8% on top of your regular rate. The RSU vest and the 409A payout themselves are not investment income, so they don’t directly trigger NIIT — but they raise your MAGI so high that every other dollar of investment income you add does get taxed at the surcharge.

The implications for the spike year:

1. Do not sell appreciated assets this year unless you have to. A long-term gain that would normally cost 15% now costs 15% + 3.8% = 18.8%, and a short-term gain is taxed at your 35% ordinary rate plus the 3.8% NIIT.
2. Do harvest losses. Selling losing positions generates capital losses that offset any gains dollar-for-dollar, plus up to $3,000 against ordinary income, with the rest carried forward. In a spike year those carried-forward losses are extra valuable.
3. Push discretionary income into next year. If you control the timing of a bonus, an invoice, or a Roth conversion, keep it out of the spike year.

What most people miss: you can sometimes split the 409A payout

The widespread belief is that a deferred-comp balance must come out as a single lump sum the moment you leave. Often it doesn’t. Under IRC §409A, the form and timing of the payout are governed by the election you made when you deferred — and many plans allow installment payouts over 2, 5, or 10 years, or a fixed payout date, instead of a lump sum at separation.

If Priya’s plan permits installments, taking her $150,000 over two years — say $75,000 in 2026 and $75,000 in 2027 — could keep a chunk of it below the 35% threshold in each year instead of piling it all onto a single 35% stack. The catch: §409A election changes are tightly restricted. You generally must elect the payout schedule years in advance, and any change to a payout election requires the “5-year/12-month” rule (the new payout date must be at least five years later, and the change made at least 12 months before the original date). You can’t restructure it on the way out the door. Check your plan’s distribution election before the layoff event whenever you can — that is the only window where this lever exists.

The second thing people miss: the 22% supplemental withholding is not your tax bill. It is a deposit, and in a spike year it is a badly undersized one. Withholding $0.22 on a dollar that’s actually taxed at $0.35 leaves a 13-cent gap on every supplemental dollar. On Priya’s $400K of RSU + 409A income, that is roughly a $52,000 shortfall waiting at filing. Set the cash aside, and consider a fourth-quarter estimated payment to avoid an underpayment penalty.

Putting the four levers together

These figures assume Priya has the cash flow to fund the retirement, HSA, and charitable contributions — which in a year she received $400K of windfall compensation, she generally does. If she also starts self-employment and opens a Solo 401(k), the deductible-retirement line alone can grow toward $72,000, pushing total tax saved past $40,000. None of these levers requires her to spend money she wouldn’t otherwise save or give — they simply route those dollars through the most tax-efficient channel in the one year it matters most.

The decision lever

You can’t move accelerated RSUs or a forced 409A payout out of your layoff year — both are ordinary income the moment they land, and they stack at the same graduated rates. What you control is everything that sits beside them on the return: how much pre-tax retirement and HSA you fund, whether you bunch charitable giving (ideally with appreciated stock) into the 35% year, whether you harvest losses instead of realizing gains while your MAGI is sky-high, and — if you set it up early enough — whether your deferred-comp election spreads the payout across two tax years instead of one. Pull those levers in that order, set aside cash for the 13-cent withholding gap on every supplemental dollar, and a $580K spike year costs far less than the flat-22%-withholding statement led you to expect.
