401(k) After a Layoff: Rollover Strategy, Roth Conversion Window & Rule of 55

A layoff reshapes your finances on multiple fronts at once: income drops, health insurance changes, and your 401(k) becomes a decision you can no longer defer. Most people focus on the stress of the transition and miss the hidden opportunity: a lower-income year is often the single best window in your career to execute Roth conversions at a below-normal tax rate. This guide covers everything you need to decide about your 401(k) in the weeks after a layoff — including the Rule of 55, the loan offset trap, how severance affects your timing, and how to coordinate Roth conversions with your health insurance decision.

What happens to your 401(k) immediately after a layoff

Your employer terminates your active participation in the plan, but your vested balance stays put. The plan cannot distribute your balance without your authorization except in one case: if your vested balance is $7,000 or less, SECURE 2.0 § 304 (effective 2024) allows the plan to automatically roll it to an IRA — typically a low-cost rollover IRA set up by the recordkeeper.¹ Balances above $7,000 remain in the plan indefinitely.

One vesting check before you do anything: employer matching and profit-sharing contributions are subject to 2–6 year vesting schedules. If you were laid off before you were fully vested, you forfeit the unvested portion — it doesn't come with you regardless of what you do with the rest. See the vesting schedule guide to calculate exactly what you'd lose.

Your four options — layoff context

The four options at job departure are the same as any job change, but layoff adds specific texture to each:

Most layoff situations land in the first two options. The core question is whether you're 55 or older — that changes the analysis significantly.

The Rule of 55: does your layoff qualify?

Under IRC § 72(t)(2)(A)(v), you can take penalty-free withdrawals from a 401(k) — at any amount, any schedule — if you separated from service from that employer in or after the year you turned 55.² Public safety employees (police, fire, EMT) get an earlier age of 50.

Three nuances that matter most in a layoff:

• It's tied to the plan, not the person. The exception applies only to the 401(k) at the employer you were laid off from. Old 401(k)s from previous employers don't get it. A rolled-to IRA never gets it. To access penalty-free distributions under this rule, you must keep the money in the old employer's plan — rolling to an IRA forfeits the exception permanently.
• The "in or after the year you turned 55" rule is lenient. You don't have to be 55 on the day of the layoff — you just have to turn 55 at some point in the same calendar year as your separation. Laid off in January, birthday in December? You qualify for the year.
• WARN Act and severance period. If your employer provided 60-day WARN Act notice or paid severance in lieu of notice, your "separation from service" date for Rule of 55 purposes is your actual last day of work — not when severance payments end. Verify the Form 1099-R distribution coding with your plan administrator.

If you're 54 at layoff and turn 55 next year, the Rule of 55 is gone — rolling to an IRA doesn't create a workaround. Your remaining penalty-free options are SEPP 72(t) payments (see the SEPP calculator) or specific exceptions (disability, medical expenses exceeding 7.5% of AGI, substantially equal periodic payments). See the full Rule of 55 guide.

If you have an outstanding 401(k) loan

Most plans require immediate repayment of any outstanding 401(k) loan upon termination. If you can't repay, the plan offsets the loan balance against your account — treating the unpaid balance as a distribution — and issues a Form 1099-R coded as an early distribution.

The critical deadline: under the TCJA 2017 (IRC § 402(c)(3)(C)), you have until your tax filing due date including extensions — typically October 15 of the following year — to replace the offset amount with personal funds rolled into a traditional IRA.³

The Roth conversion opportunity: your lowest-income year

This is what most people miss. The year you're laid off — especially if the layoff happens mid-year — is often the lowest-income year in your career. That creates a rare window to convert pre-tax retirement money to Roth at a rate you may never see again.

Estimate your Roth conversion capacity during a layoff year

Why a layoff year is often the best conversion window

In a normal year, a $130,000 earner (single) has taxable income of about $113,900 — already past the 22% bracket ceiling ($105,700) and into 24%. In the year of a mid-year layoff where they earned only $55,000 in salary, taxable income drops to $38,900 — deep in the 12% bracket with $11,500 of room to convert before crossing into 22%.

Converting $11,500 at 12% costs $1,380 in federal tax. At their normal 24% rate, the same conversion costs $2,760. Tax saved on a single year's conversion: $1,380. Over 25 years of tax-free Roth growth at 7%, that $11,500 becomes approximately $62,000 — all tax-free. The decision compounds.

For larger balances where a single conversion would push you well into 22% or 24%, the math still often favors converting at a temporarily reduced rate vs. paying your expected future rate in retirement — especially if you expect future RMDs to push income into higher brackets.

Three things to coordinate before converting

• Severance timing. A large lump-sum severance received in the layoff year increases your income and may push you into a higher bracket than expected. In that case, deferring conversions to next year — when income starts clean at zero — may produce a lower effective rate. Structured severance paid over multiple years gives more flexibility.
• ACA marketplace health insurance. If you're using ACA marketplace coverage, Roth conversion amounts count as Modified Adjusted Gross Income (MAGI) for premium tax credit calculations. A large conversion late in the year can create an unexpected reconciliation amount at tax time. If you enrolled at marketplace at a low income estimate, a $50,000 conversion added in December will likely require repaying a portion of advance credits. Model this before converting large amounts in a marketplace-coverage year.
• State income tax. Most states with an income tax treat Roth conversions as ordinary income. Pennsylvania and Illinois are notable exceptions that exclude certain retirement income — verify your state's treatment before converting. The calculator above shows federal tax only.

COBRA vs. ACA marketplace: the health insurance and conversion interaction

Losing employer-sponsored coverage triggers two options. The decision has real implications for your Roth conversion flexibility.

COBRA: You have 60 days from the qualifying event notice to elect COBRA continuation coverage.⁴ It keeps your exact current plan and in-progress deductible. The cost is 102% of the full premium — your prior employee share plus what your employer was paying — for up to 18 months. COBRA is typically more expensive than marketplace coverage but income-neutral: premiums don't change based on your income, and choosing COBRA doesn't affect your ability to execute Roth conversions without a subsidy interaction problem.

ACA marketplace: Losing job-based coverage opens a 60-day special enrollment window. Marketplace premiums can be lower if your income qualifies for premium tax credits. The tradeoff: different plan and network, a new deductible year, and — if you receive credits — Roth conversion amounts directly increase the income on which credits are calculated.

A common strategy for people with large balances and a planned multi-year conversion sequence: use COBRA for the first 6–12 months to preserve conversion flexibility, then shift to marketplace once the primary conversion window has passed.

Three real-dollar layoff scenarios

Scenario A: Mid-career tech layoff, age 42, $380,000 in old 401(k)

Laid off in June 2026 after earning $90,000 year-to-date. Severance: $20,000 lump sum. Total 2026 income: $110,000. Standard deduction (single): $16,100. Taxable income: $93,900 — in the 22% bracket. Room to top of 22% bracket: $105,700 − $93,900 = $11,800.

Strategy: Roll 401(k) to a traditional IRA at Fidelity (no Rule of 55 concern at 42). Convert $11,800 to Roth at 22% ($2,596 federal tax). Leaves $368,200 in traditional IRA. New job next year at $130K means the conversion window narrows — the layoff year was the marginal opportunity. Choosing IRA over keeping in old plan because old employer's plan had 0.78% weighted expense ratio vs. Fidelity's FZROX at 0.00%. See custodian comparison guide.

Scenario B: Near-retirement layoff, age 56, $920,000 in old 401(k), Rule of 55 eligible

Laid off in March 2026 at age 56. Earned $45,000 in salary before layoff. Spouse works; household income: $185,000 total (MFJ). Taxable income: $185,000 − $32,200 std ded = $152,800 — solidly in 22% bracket, and only $58,600 of room remains before crossing into 24% (MFJ 22% ceiling: $211,400 taxable = $243,600 gross).

Strategy: Keep 401(k) in old employer's plan — Rule of 55 is worth more than the conversion room this year. Draw $3,500/month from the old 401(k) penalty-free while job-searching (no IRS approval required; no fixed-schedule commitment). If job search extends into 2027 with zero new income, that year's income drops dramatically and the conversion window reopens at a lower rate. If re-employed, roll to IRA at the new employer. Do not roll now — forfeiting Rule of 55 on $920,000 eliminates a valuable safety valve. See the rollover at retirement guide.

Scenario C: Early layoff, age 38, $85,000 in old 401(k), $12,000 outstanding loan

Laid off in August 2026 after earning $35,000 year-to-date (part-year). Outstanding 401(k) loan: $12,000. Plan demands repayment; can't repay. Plan offsets $12,000, issues Form 1099-R (code 1).

QPLO opportunity: Has until October 15, 2027, to deposit $12,000 of personal cash into a traditional IRA to avoid the $1,200 penalty plus ordinary income tax. Remaining $73,000 rolls to a traditional IRA. Taxable income in 2026: $35,000 salary − $16,100 std ded = $18,900 — in the 12% bracket with $31,500 of room. Could convert $31,500 to Roth at exactly 12% ($3,780 federal tax) — likely the best conversion window this person will ever see. The early layoff created a silver lining that nearly any financial advisor would recommend acting on before year-end. See loan offset rollover guide and Roth conversion calculator.

Decision sequence for a laid-off employee

1. Check vesting status. Confirm how much of your balance is actually yours to roll. See the vesting schedule guide.
2. Check for outstanding loans. If yes, note the QPLO October 15 deadline for next year and decide whether to repay out of pocket or accept the offset and roll it later. See the loan offset guide.
3. Assess Rule of 55 eligibility. Were you 55+ in the calendar year of layoff? If yes, consider keeping the money in the old plan for penalty-free access. See the Rule of 55 guide.
4. Estimate your layoff-year income. Salary earned + severance + other = total income. Use the calculator above to find your Roth conversion capacity.
5. Decide on health insurance. COBRA vs. ACA marketplace affects your MAGI flexibility for conversions. If choosing marketplace, factor conversion amounts into your enrollment income estimate.
6. Execute rollover and any conversions before December 31. Use a direct rollover to avoid the 20% withholding trap. Convert the targeted Roth amount before year-end.
7. Get professional advice on balances over $200K. A fee-only advisor can model the full multi-year conversion sequence and coordinate with Social Security timing, RMDs, and IRMAA. The layoff year is usually the entry point for a conversion ladder — the sequencing matters more as balances grow.
