401(k) Loan Offset When Leaving a Job: The QPLO Rollover Window

You left your job — or you're about to — and you have an outstanding 401(k) loan. Here's what the plan does next, why it triggers a tax bill you might not be expecting, and how a little-known rule gives you until your tax filing deadline (not just 60 days) to undo the damage by rolling the offset amount into an IRA.

What is a plan loan offset?

A plan loan offset occurs when the plan reduces your vested account balance by the outstanding loan amount because you can no longer repay it. You don't receive a check — the loan simply disappears from your balance. But from the IRS's perspective, the offset amount is treated as a taxable distribution from the plan.¹

The plan will issue a Form 1099-R showing the offset as a distribution. If you're under 59½, it is also subject to the 10% early withdrawal penalty unless an exception applies — and rolling over the offset to an IRA is exactly that exception.

Two types of offset: QPLO vs. regular default

Not all loan offsets are created equal. The rules depend on why the offset occurred.

The formal definition of a Qualified Plan Loan Offset (QPLO), enacted by the Tax Cuts and Jobs Act of 2017 (TCJA § 13613) and codified at IRC § 402(c)(3)(C), covers two triggers: plan termination and separation from employment.² For separation from employment, the offset must also occur within 12 months of your separation date — if the plan waits longer to collect, the extended window closes and you're back to 60 days.³

The QPLO extended rollover window — what changed in 2018

Before the TCJA took effect for tax years beginning after December 31, 2017, the deadline to roll over any plan loan offset was 60 days from the date of the offset — the same as any indirect rollover. If you left your job in November and the plan offset your $30,000 loan balance in December, you had until February to come up with $30,000 in cash and deposit it into an IRA. Most people couldn't, and most people ended up with an unexpected $30,000 tax bill.

The QPLO rule changed that. For qualifying offsets, the rollover deadline is now the due date (including extensions) of your federal income tax return for the year in which the offset occurs. For most people, that means:

• Offset in tax year 2026 → standard due date is April 15, 2027
• File a six-month extension (Form 4868) → deadline becomes October 15, 2027

That's up to 21 months from the date of the offset to roll over the amount, compared to 60 days under the old rule. The mechanics are the same — you contribute cash to an IRA, designate it as a rollover, and the income tax exclusion applies — but the timeline is far more workable.

Where can you roll over a QPLO?

A QPLO amount can be rolled over to any eligible retirement plan:¹

• Traditional IRA — tax-free rollover; no income is recognized. This is the most common destination.
• New employer's 401(k), 403(b), or 457(b) — if the plan accepts incoming rollovers (many do). Eliminates pro-rata rule exposure for backdoor Roth users.
• Solo 401(k) — if you're self-employed and have established one.
• Roth IRA — allowed, but this converts the offset amount to Roth; you owe ordinary income tax on it (no 10% penalty since the rollover is timely). Only do this deliberately as part of a Roth conversion strategy, not to avoid the tax — you can't avoid tax on a Roth conversion.

Practical steps: what to do after a job-change loan offset

Step 1 — Confirm whether your offset qualifies as a QPLO

Ask your plan administrator (in writing): "Is this a qualified plan loan offset under IRC § 402(c)(3)(C)?" The plan is required to report the offset on Form 1099-R and must designate whether it is a QPLO using code "M" in Box 13 (Loans treated as distributions) or equivalent QPLO indicator. If the plan says yes, you have the extended window. If the plan says no — or if the offset occurred more than 12 months after your separation date — you have 60 days.

Step 2 — Determine how much you can roll over

You can roll over up to the full QPLO amount. You do not have to roll the entire amount — if you roll half, you owe tax on the other half. There is no minimum. The rollover cannot exceed the offset amount (you can't use a QPLO as an excuse to make a larger-than-normal IRA contribution).

The 2026 IRA annual contribution limit ($7,500, or $8,500 at age 50+) does not cap rollover contributions. QPLO rollovers are rollovers, not regular contributions — they are not subject to annual limits.

Step 3 — Open a traditional IRA if you don't have one

You need a destination account. Fidelity, Vanguard, and Schwab all allow you to open a traditional IRA online in minutes. You do not need the new account to be specifically labeled "Rollover IRA" — a standard traditional IRA works. See our rollover IRA custodian comparison for a brief overview.

Step 4 — Fund the rollover from cash

You cannot transfer the 401(k) loan itself — the loan no longer exists. You contribute cash to the IRA. Common sources: savings account, taxable brokerage account proceeds, or a short-term personal loan. When you make the IRA contribution, designate it explicitly as a rollover contribution (not a regular annual contribution). The IRA custodian may ask you to complete a rollover contribution form or select "rollover" in the deposit flow.

Step 5 — File Form 8606 if needed; track your Form 1099-R

The plan will issue a Form 1099-R for the distribution. Box 1 shows the offset amount; Box 2a shows the taxable amount (same figure unless you have after-tax basis in the plan). Box 7 will show a distribution code — typically "1" (early distribution, no known exception) or "M" to indicate QPLO status. When you file your tax return, you report the distribution from Form 1099-R and the offsetting rollover contribution. Your tax software will walk you through this; the net result is $0 in taxable income on the offset.

Step 6 — File a tax extension if you need more time (for QPLO offsets)

The QPLO extended deadline is tied to your tax return filing deadline. Filing a Form 4868 extension by April 15 extends your filing deadline to October 15 — and simultaneously extends your QPLO rollover deadline to October 15. You do not need to actually file a return by April 15; you only need to file the extension request. You still owe any tax due by April 15, but the rollover window itself extends to October 15.

Non-QPLO offset scenarios: when 60 days is all you get

Missed loan payments while still employed

If you default on a 401(k) loan — missed payments, failed to cure, plan declares the loan in default — while you're still at that employer, the deemed distribution occurs at the point of default. This is not a QPLO (the offset did not happen due to separation from service or plan termination). The standard 60-day indirect rollover window applies. In practice, most people in this situation don't have 60 days' worth of cash available, and the deemed distribution becomes fully taxable. The one saving grace: unlike a QPLO, a deemed distribution from a loan default does not reduce your plan balance — the outstanding principal continues to accrue until it's eventually set off against your account at distribution or separation. This creates a "double taxation" problem on the principal (you pay tax now on the deemed distribution, and again when you actually distribute the account unless you track the basis on Form 1099-R), which is one more reason to avoid defaulting while still employed.

Offset more than 12 months after separation

If your former employer's plan takes longer than 12 months after your separation date to collect on the outstanding loan — and this does happen, particularly with small plans that are slow to process separating employees — the offset no longer qualifies as a QPLO under the final regulations (TD 9937).³ You're left with the standard 60-day window from the date the offset actually occurs. Monitor your former plan account after leaving; if you have an outstanding loan, don't assume the plan will notify you before the QPLO window closes.

How a QPLO interacts with the rest of your rollover

Pro-rata rule and backdoor Roth

Rolling the QPLO amount into a traditional IRA adds pre-tax dollars to your IRA pool — which activates the pro-rata rule if you make backdoor Roth contributions. If you're a backdoor Roth user with a zero IRA balance, consider rolling the QPLO into your new employer's 401(k) instead (if the plan accepts it), keeping your IRA clean. See our pro-rata rule guide and reverse rollover guide for the mechanics.

NUA on employer stock

If your 401(k) also contains highly appreciated employer stock, an outstanding loan complicates the NUA lump-sum distribution requirement. The NUA strategy under IRC § 402(e)(4) requires a "lump-sum distribution" — you must distribute your entire balance from all plans of that employer in a single tax year. A loan offset counts as a distribution for this purpose, but the logistics of coordinating an NUA in-kind distribution with an outstanding loan require careful sequencing. Consult an advisor before initiating if both issues are present simultaneously. See our NUA employer stock guide.

Rule of 55 interaction

The Rule of 55 (IRC § 72(t)(2)(A)(v)) exempts 401(k) distributions from the 10% penalty if you separate from service at age 55 or older. If the Rule of 55 applies to your distribution, the 10% penalty on the loan offset is waived regardless of whether you roll it over. But rolling it over is still beneficial — it preserves the capital and defers income tax. See our leave-vs.-rollover guide for the Rule of 55 framework.

Common QPLO mistakes

• Assuming you have 60 days. The old 60-day rule still applies to non-QPLO offsets. If you qualify for the QPLO extended window, confirm it with the plan administrator before assuming a shorter deadline.
• Waiting until April to act, missing the extension option. If you don't file a Form 4868 by April 15, your deadline to roll over is April 15 — not October 15. The extension is not automatic; you must request it.
• Rolling the QPLO into a Roth IRA thinking it avoids tax. Rolling to a Roth IRA is a taxable conversion. Tax-free rollover requires a traditional IRA or eligible pre-tax plan destination.
• Forgetting about pro-rata rule consequences. Adding pre-tax IRA balance breaks backdoor Roth. Plan the destination account before funding the rollover.
• Not tracking the Form 1099-R. The plan will issue a 1099-R for the offset. Failing to reconcile it on your tax return — reporting the distribution and the offsetting rollover — can result in the IRS matching the 1099-R and sending a notice for unreported income.
