Severance and 401(k) Loan Repayment — 2026 Offset Rules

Who this applies to#

Taking a loan from your 401(k) is common — roughly one in five active participants carries an outstanding plan loan at any given time. What most employees do not realize until their last day is that separation from employment typically triggers an accelerated repayment obligation. If you cannot repay the loan in cash, the plan offsets the outstanding balance against your vested account, reducing what you receive. That offset is treated by the IRS as a taxable distribution. This page covers the current legal framework in 2026. The key rule governing rollover of a plan loan offset — the ability to avoid tax by contributing an equivalent amount to an IRA or eligible retirement plan — was updated by the Tax Cuts and Jobs Act of 2017 and is codified at 26 U.S.C. § 402(c)(3)(C). It gives you until the federal income tax return due date, including extensions, to complete the rollover. An important note: the CARES Act of 2020 created a temporary one-year deferral of plan loan repayment for COVID-19-affected participants. That provision is fully expired and is not applicable in 2026. The stakes are significant. A mid-career employee who borrows $40,000 from their 401(k) and cannot repay it at layoff faces ordinary income tax on the full amount (potentially pushing them into a higher bracket in a year that already includes severance) plus a 10% early-withdrawal penalty under § 72(t) if they are under 59½ — a combined cost that can exceed 35% of the loan balance in many states.

What changes for you#

When you take a loan from a qualified employer plan, § 72(p)(2) exempts it from immediate distribution treatment provided the loan does not exceed $50,000 (reduced by your highest outstanding balance in the prior 12 months), is repaid within 5 years (except home-purchase loans), and requires level quarterly payments. If any of these conditions are violated, or if you separate from employment and the plan exercises its right to offset the loan balance, the outstanding amount becomes a deemed distribution. Plan loan offset mechanics: when a plan offsets your outstanding loan balance against your vested account at separation, it reduces your account balance by the loan amount and issues a Form 1099-R reporting the offset as a distribution. This is called a qualified plan loan offset (QPLO). You are taxed on the offset amount as ordinary income, and the 10% early-withdrawal penalty under § 72(t) applies if you are under 59½. Rollover window under § 402(c)(3)(C) — current law: the TCJA 2017 created a special, longer rollover window for QPLOs. Instead of the standard 60-day rollover period, you have until the due date (including extensions) for filing your federal income tax return for the year in which the offset occurred. For most individuals, this is October 15 of the following year. To avoid tax, you contribute an amount equal to the loan offset to an IRA or another eligible retirement plan by that deadline. The contribution is not limited to the offset amount — you can use other cash — but you must report it correctly on Form 5498. Note on historical 60-day rule: before TCJA 2017, QPLOs were subject to the standard 60-day rollover window. That pre-2017 rule is now superseded for QPLOs. However, for a non-QPLO deemed distribution (e.g., a loan that exceeded the § 72(p)(2) limits during employment), the standard 60-day window still applies. Note on CARES Act 2020: the CARES Act temporarily allowed COVID-affected participants to delay plan loan repayments by one year during 2020. That provision is expired and irrelevant to 2026 separations. If you do not roll over the QPLO by the filing deadline: the offset amount is included in your gross income for the year of separation. The 10% penalty under § 72(t) applies if you are under 59½. Federal withholding at 20% is typically applied to the offset when it is processed — that withholding reduces your refund or tax bill at filing but does not eliminate the underlying income inclusion.

Decision tree#

1. If Do you have an outstanding 401(k) loan at the time you separate from employment?

   Then → The plan may require immediate repayment or will treat the outstanding balance as a plan loan offset — a deemed distribution. Proceed through the analysis.

   Else: No § 72(p) issue. Standard 401(k) rollover rules apply to your remaining balance.

2. If Did your plan treat the outstanding loan balance as a plan loan offset (deducted from your vested account balance rather than demanding cash repayment)?

   Then → You have a qualified plan loan offset (PLO) under § 402(c)(3)(C). You have until the federal income tax return due date including extensions for the year of the offset to roll the same amount to an IRA or eligible plan.

   Else: If the plan demanded cash repayment and you paid it, no deemed distribution occurred. If you missed cash repayment, the plan may have treated it as a deemed distribution under § 72(p) — review your Form 1099-R.

3. If Are you under age 59½ and did you NOT roll over the offset amount by the filing deadline?

   Then → The offset amount is ordinary income AND subject to the 10% early-withdrawal penalty under § 72(t). You may also owe a 10% underpayment penalty if you did not withhold or estimate sufficiently.

   Else: If you are 59½ or older, the offset is ordinary income but the 10% penalty does not apply. If you did roll over the offset, no income or penalty is triggered.

Action steps#

• Check your 401(k) plan document and your most recent loan statement to determine exactly how much you owe. Many plans require immediate full repayment upon separation; others give a grace period (often through the end of the quarter or the following quarter).
• Ask your plan administrator whether any unpaid balance will be treated as a qualified plan loan offset or as a cash demand. If it is a QPLO, you have until the federal income tax return due date including extensions to roll over the same amount.
• If you will receive a Form 1099-R reporting the offset as a distribution, do not ignore it. Set aside the rollover amount in a separate account so it is available by October 15 of the following year (or the earlier deadline if you do not file for extension).
• Calculate the combined tax impact: ordinary income tax on the offset at your marginal rate, plus the 10% early-withdrawal penalty if you are under 59½, plus any state income tax. Confirm whether your severance income in the same year pushes you into a higher federal bracket.
• If you cannot afford to roll over the full offset amount, roll over as much as you can — partial rollovers reduce taxable income proportionally.
• Do not rely on the CARES Act 2020 extended repayment window. That provision expired in 2021 and has no effect on 2026 separations.
• Keep records of all rollover transactions and report them accurately on Form 1040 and Form 5498. Rollover contributions reduce the taxable portion of the 1099-R distribution.

FAQ#

What is a plan loan offset and why does it matter at layoff?

A plan loan offset occurs when your 401(k) plan reduces your vested account balance by the amount of your outstanding loan, typically because you separated from employment and cannot repay in cash. Under 26 U.S.C. § 72(p)(1), the offset amount is treated as a distribution — meaning it is includible in your gross income and, if you are under 59½, subject to the 10% early-withdrawal penalty under § 72(t).

How long do I have to roll over a plan loan offset?

Under current law (26 U.S.C. § 402(c)(3)(C), added by TCJA 2017), you have until the due date, including extensions, for filing your federal income tax return for the year in which the offset occurred. For most taxpayers who file for extension, that is October 15 of the following year. To avoid tax, you contribute an equivalent amount to an IRA or another eligible retirement plan by that deadline.

Does the CARES Act 2020 one-year deferral still apply?

No. The CARES Act of 2020 allowed COVID-affected participants to delay plan loan repayments by one year and waived required minimum distributions for 2020. Those provisions are fully expired and have no effect on 2026 plan loan obligations. The current rule for qualified plan loan offsets is the extended rollover window under § 402(c)(3)(C) — not any CARES Act provision.

What if I only partially repay the offset?

Partial rollovers reduce the taxable portion proportionally. If you offset $30,000 but can only roll over $20,000 by the filing deadline, $10,000 remains taxable as ordinary income and is subject to the 10% penalty if you are under 59½. Contributing what you can is always better than contributing nothing — each dollar rolled over reduces your tax bill.

Does my severance payment affect the tax on the loan offset?

Yes, potentially. Both the offset amount and your severance are ordinary income in the same year. If their combined total pushes you into a higher marginal bracket, more of the offset is taxed at that higher rate. Consider whether delaying the start of any salary-continuation severance into the following calendar year could reduce the combined tax hit — though that depends on your severance agreement and the timing of the offset.

What happens to the 20% mandatory withholding on the offset?

Plans are generally required to withhold 20% of an eligible rollover distribution, including plan loan offsets. That withholding is applied against your year-end tax liability. However, if you want to roll over the full offset amount and restore the full pretax balance, you must fund the rollover with outside money — including an amount equal to the 20% withheld — and then recover the withheld amount as a credit or refund when you file your return. In practice, plans can only withhold from cash being distributed at the same time as the offset — if your offset is the sole event with no cash distribution, no withholding may apply, but you still owe the tax.

Are there exceptions to the 10% early-withdrawal penalty?

Yes. Section 72(t) lists numerous exceptions, including distributions after age 59½, disability, death, substantially equal periodic payments (SEPPs), certain medical expenses exceeding 7.5% of AGI, and distributions to qualified military reservists. Most of these exceptions apply to the loan offset treated as a distribution. Consult IRS Publication 575 for the full list and the specific conditions each exception requires.

Does a 401(k) loan offset affect my severance negotiation?

It can. If you have a large outstanding loan, you may want to negotiate a higher lump-sum severance to fund the rollover and avoid the tax and penalty hit. Alternatively, if your plan gives a grace period — often through the end of the next quarter — you may have time to repay part of the loan in cash using your severance before the offset is processed. Ask your plan administrator about the exact repayment deadline before finalizing any severance agreement.
