When you leave a job with an unpaid 401(k) loan, the plan typically settles the debt by subtracting the outstanding balance from your account. That subtraction is called a 401(k) plan loan offset, and the IRS treats it as a distribution: taxable income for the year, plus a 10% early distribution penalty if you’re under 59½, unless you roll an equivalent amount into an IRA or another employer plan by your tax filing deadline.
What a Plan Loan Offset Actually Is
A plan loan offset happens when the plan reduces your account balance to extinguish an outstanding loan. The loan is gone. You no longer owe the plan anything. But the amount that was written off is now treated as money distributed to you, even though no cash ever changed hands.
An example makes the mechanics clearer. You leave your job with a $45,000 vested balance and an $8,000 loan still outstanding. The plan subtracts the $8,000, cancels the loan, and distributes or rolls over the remaining $37,000. That $8,000 is a distribution on your tax return unless you take steps to roll it over.
When an Offset Gets Triggered
Offsets don’t happen at random. They require a distributable event — a moment when the plan is allowed to pay out your balance. The two common triggers are leaving your employer and the employer terminating the plan.1Internal Revenue Service. Retirement Topics – Loans Many plans require full repayment when you separate from service; if you can’t write a check for the remaining balance, the plan simply deducts it from your account.
Offset vs. Deemed Distribution
A related event, the deemed distribution, looks similar on the surface and carries much worse consequences. It’s worth knowing which one you’re dealing with before you file anything.
A deemed distribution happens when a loan falls out of compliance while you’re still employed, usually because you missed payments and didn’t catch up during the plan’s cure period. The IRS then treats the outstanding balance as if it were distributed to you.2Internal Revenue Service. Plan Loan Failures and Deemed Distributions You owe income tax on the full amount, but the loan doesn’t go away. You still owe it to the plan.
Three practical differences matter:
- A plan loan offset wipes out the loan. A deemed distribution does not; the debt remains on the plan’s books.
- A plan loan offset is an actual distribution and can be rolled over to preserve its tax-deferred status. A deemed distribution cannot be rolled over at all.3Internal Revenue Service. Plan Loan Offsets
- An offset requires a distributable event like separation or plan termination. A deemed distribution can happen while you’re still employed, the moment your loan falls out of compliance.
If you’re reading this because you left a job with a loan outstanding, you’re almost certainly looking at an offset, which is the better of the two situations to be in.
Rolling Over a Qualified Plan Loan Offset
The Tax Cuts and Jobs Act created a category called a qualified plan loan offset, or QPLO. An offset qualifies as a QPLO if the loan was in good standing at the time and the offset happened because you left your employer or the plan terminated.
The advantage is time. Instead of the standard 60-day rollover window, you have until your federal tax filing deadline, including extensions, for the year the offset happened.3Internal Revenue Service. Plan Loan Offsets An offset that occurs in 2025 can be rolled over as late as April 15, 2026, or October 15, 2026 with an extension.
The mechanics catch people off guard. The plan doesn’t hand you cash for the offset portion; that money went to pay off your loan. To complete the rollover, you have to come up with the offset amount from personal savings or another source and deposit it into an IRA or an eligible employer plan. Roll over the full amount and you owe no income tax and no early distribution penalty. Roll over part of it and you pay tax on whatever you didn’t replace.3Internal Revenue Service. Plan Loan Offsets
Non-Qualified Offsets and the 60-Day Rule
If your loan was already delinquent when the offset occurred, it doesn’t meet the QPLO definition. You can still roll it over, but only within 60 days of the distribution date.3Internal Revenue Service. Plan Loan Offsets That’s a tight window, especially in the middle of a job transition. Miss it, and the full offset becomes taxable income for the year.
What It Costs If You Don’t Roll It Over
Skip the rollover and the offset amount is added to your ordinary income for the year. On a $5,000 offset, someone in the 22% bracket owes $1,100 in federal income tax. If you’re under 59½, the 10% early distribution penalty applies on top of that, adding $500.4Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions That’s $1,600 gone on a $5,000 balance, and the money is permanently out of your retirement account. State income tax, where applicable, adds more.
The rollover math often looks better than it first appears. You do have to find the cash somewhere, which is real. But you’re moving after-tax dollars from one pocket into a tax-deferred account, avoiding an immediate tax bill, and keeping the balance compounding for retirement. Compared with letting the offset stand as a distribution, it’s usually the cheaper outcome by a wide margin.
How the Offset Shows Up on Form 1099-R
The plan administrator reports the event on Form 1099-R, which goes to you and to the IRS. The distribution code in Box 7 tells the IRS what kind of event happened and controls your rollover options:
- Code M means a qualified plan loan offset. The offset resulted from job separation or plan termination while the loan was in good standing, and the extended tax-filing-deadline rollover window applies.5Internal Revenue Service. Instructions for Forms 1099-R and 5498
- Code L means a deemed distribution. The loan failed while you were still in the plan, and the amount cannot be rolled over.5Internal Revenue Service. Instructions for Forms 1099-R and 5498
- Other codes, typically Code 1 for an early distribution under 59½, apply to a non-QPLO offset. The IRS specifically instructs administrators not to use Code L for offsets.3Internal Revenue Service. Plan Loan Offsets
When you file, report the gross distribution from the 1099-R. If you completed a rollover, show the taxable amount as reduced or zero and note the rollover on your return. If the code on the form doesn’t match what you believe happened — say, the plan issued Code L for what should have been Code M — contact the administrator before filing. A mismatch between your return and the 1099-R usually generates an IRS notice.
What To Do Now
If you’ve just separated from a job with a loan outstanding, three items are worth confirming quickly. Ask the plan administrator whether the loan was in good standing at separation and which Box 7 code they’ll report; that determines whether you get the extended QPLO deadline or the 60-day window. Identify where you can source the cash to complete the rollover — personal savings, a new employer’s plan that accepts rollovers, or an IRA you already hold. Then calendar the deadline. For a QPLO, that’s your tax filing deadline with extensions for the year of the offset. For a non-QPLO, count 60 days from the distribution date and treat that as firm.
