A qualified plan loan offset is what happens when you leave a job (or your employer terminates the retirement plan) with an unpaid 401(k) loan, and the plan reduces your account balance by the outstanding loan amount to settle it. The IRS treats that reduction as a distribution and taxes it as ordinary income unless you roll an equal cash amount into an IRA or another employer’s qualified plan. Under a rule added by the Tax Cuts and Jobs Act of 2017, you have until the due date of your federal income tax return for the year of the offset, including extensions, to complete that rollover.1Federal Register. Rollover Rules for Qualified Plan Loan Offset Amounts
What Triggers the Offset
While you’re employed and making scheduled payments, a 401(k) loan isn’t a distribution and isn’t taxed. The offset only appears when repayment breaks down. Most plans require the full outstanding balance to be repaid if you leave the employer or if the plan itself is terminated, and they give you a limited window to do it.2Internal Revenue Service. Retirement Topics – Plan Loans If you can’t pay in time, the plan cancels the loan by reducing your account balance by the unpaid amount. That reduction is the offset, and the IRS treats it as an actual distribution from the plan.3Internal Revenue Service. Plan Loan Offsets
You already got the economic benefit of the money when you borrowed it. No new cash lands in your bank account at the offset, but for tax purposes the funds have left the retirement wrapper, and the IRS treats them the same as a cash withdrawal.
QPLO vs. Regular Plan Loan Offset
This distinction controls your deadline, so check it before you do anything else. A regular plan loan offset gets only the standard 60-day rollover window that applies to any eligible rollover distribution. A qualified plan loan offset amount (QPLO) gets the extended deadline that runs all the way to your tax filing due date, including extensions.3Internal Revenue Service. Plan Loan Offsets
To qualify as a QPLO, two conditions have to be met:
- The offset happened solely because the plan was terminated, or because you couldn’t keep repaying the loan after leaving your job.
- Immediately before that triggering event, the loan met the requirements of IRC Section 72(p)(2): the balance didn’t exceed the lesser of $50,000 or 50% of your vested account balance, and you were paying it back in substantially level installments over no more than five years (longer only if used for a primary residence).4Internal Revenue Service.

There’s also a timing rule for severance-related offsets: the offset must occur within 12 months of the date you left your job.3Internal Revenue Service. Plan Loan Offsets Wait longer than a year and the extended window is gone.
One trap catches people constantly. If your loan was already in default before you left the job (say you stopped making payments months earlier while still employed) the earlier default created a deemed distribution when it happened, not a QPLO. Deemed distributions don’t qualify for the extended rollover period at all.5Internal Revenue Service. Retirement Plans FAQs Regarding Loans
How to Complete the Rollover
The offset doesn’t put cash in your hands, so you have to source the money elsewhere: savings, a taxable brokerage account, or any other funds you can pull together. Contribute that cash to a traditional IRA (or, if the new plan accepts rollovers, an employer’s qualified plan) in an amount equal to the offset. When it’s done correctly, the full offset becomes nontaxable and any 10% early distribution penalty disappears with it.
Tell the receiving institution to code the deposit as a rollover contribution, not a regular annual IRA contribution. This matters. Regular IRA contributions are capped at $7,000 for 2025 (or $8,000 if you’re 50 or older). Rollover contributions have no dollar limit. Mislabel a $15,000 rollover as a regular contribution and you’ve created an excess contribution problem on top of everything else.
Partial rollovers work too. Whatever you contribute is excluded from income; the remainder is taxable and potentially hit with the 10% penalty. Keep the distribution statement from the old plan, bank records showing where the replacement cash came from, and the rollover confirmation from the receiving account. If the IRS questions the transaction later, you carry the burden of proof.
Practical deadline example: an offset that occurs any time in 2025 gives you until April 15, 2026 to roll it over, or October 15, 2026 if you file for a tax extension.
What It Costs If You Don’t Roll Over
With no rollover, the full offset amount is added to your gross income for the year and taxed at your ordinary federal rate. Most states will tax it too. Because it stacks on top of your other income, it can push you into a higher bracket.
If you’re under 59½, add a 10% additional tax on early distributions, calculated on the full offset amount.6Internal Revenue Service. Topic No. 558, Additional Tax on Early Distributions From Retirement Plans Other Than IRAs Several exceptions can eliminate that 10% penalty even without a rollover:7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
- You separated from the employer during or after the calendar year you turned 55 (age 50 for qualifying public safety employees).
- You are totally and permanently disabled.
- The distribution went to an alternate payee under a qualified domestic relations order.
- The distribution covers unreimbursed medical expenses over 7.5% of adjusted gross income.
The age-55 exception often applies here because an offset always involves leaving an employer, but only if you were at least 55 in the year of separation. Your age when you took the loan doesn’t matter.
No Tax Was Withheld — Plan for the Bill
The mandatory 20% federal withholding that applies to most eligible rollover distributions does not apply to a plan loan offset. Withholding is limited to the cash and property actually distributed, and an offset distributes neither.3Internal Revenue Service. Plan Loan Offsets
If you don’t roll over, you could face a large tax bill at filing time with nothing prepaid against it, plus a possible underpayment penalty. If the offset happens early in the year, make an estimated tax payment for that quarter. If it happens late, increase withholding at a new job for the remaining pay periods.
Reporting the Offset: Form 1099-R Codes
Your former plan administrator will issue Form 1099-R for the offset. The code in Box 7 tells you (and the IRS) what kind of distribution it is.
For a QPLO, the administrator enters Code M, which specifically identifies the transaction as a qualified plan loan offset and signals that the extended rollover period applies.8Internal Revenue Service. Instructions for Forms 1099-R and 5498 Code M is paired with another code for age and penalty status: Code M with Code 1 if you’re under 59½ with no exception, Code M with Code 7 if you’re over 59½, and Code M with Code B for a distribution from a designated Roth account.
Code L is different. It’s used for loans treated as deemed distributions while a participant is still in the plan (the default that happens when payments stop mid-employment). IRS instructions explicitly say not to use Code L for a plan loan offset. If Code L shows up on a 1099-R for what was actually a post-separation offset, ask the plan administrator for a corrected form.
Putting It on Form 1040
The full offset appears in Box 1 (gross distribution) and usually Box 2a (taxable amount) of the 1099-R. Without a rollover, report the Box 1 amount on Line 5a and the Box 2a amount on Line 5b of Form 1040. If the 10% early distribution tax applies, file Form 5329 to calculate and report it, and use Form 5329 as well to claim any penalty exception that isn’t already reflected on the 1099-R.9Internal Revenue Service. Instructions for Form 5329 – Additional Taxes on Qualified Plans (Including IRAs) and Other Tax-Favored Accounts
If you completed a rollover, enter the Box 1 gross amount on Line 5a, put zero (or the taxable remainder for a partial rollover) on Line 5b, and write “Rollover” next to the line. The 1099-R itself will still show the amount as taxable, and you override that on the return. Keep documentation, because IRS notices generated from the 1099-R alone are common.
Roth 401(k) Offsets
If the loan came from a designated Roth account inside your 401(k), the QPLO rules work the same way, but the rollover destination changes. Roll the offset amount into a Roth IRA, not a traditional IRA, to preserve the tax-free treatment of future growth. On the 1099-R, a Roth QPLO carries Code M combined with Code B.8Internal Revenue Service. Instructions for Forms 1099-R and 5498 Rolling the full amount into a Roth IRA keeps any earnings inside the tax-free wrapper and avoids questions about whether the distribution otherwise met the requirements for a qualified Roth withdrawal.
Common Mistakes to Avoid
Doing nothing is the biggest one. People often don’t realize the offset was a taxable event until the 1099-R arrives the following January, by which point the 60-day window (if it wasn’t a QPLO) may already have closed.
Assuming every offset is a QPLO is the second. It isn’t. A loan already in default before separation, or an offset processed more than 12 months after you left, drops you back to the 60-day rule. Check your plan statements and the Box 7 code before you plan around the extended deadline.
Contributing the replacement cash as a regular IRA contribution instead of a rollover is the third. The receiving institution has to record it as a rollover, or you’ll blow past the annual contribution limit and create an excess contribution penalty on top of the tax you were trying to avoid.
