When a retirement plan loan defaults, the tax code treats it in one of two ways, and the difference between a loan offset and a deemed distribution controls whether you can rescue the money with a rollover or end up taxed on cash you never received. A deemed distribution is a paper tax event: the plan reports the unpaid balance as taxable income, but the loan itself stays on the books and you still owe it. A loan offset is the opposite: the plan actually reduces your account balance to settle the debt, the loan is gone, and the offset amount qualifies for rollover treatment that can wipe out the tax bill entirely if you act in time.
Which one applies to you depends almost entirely on your employment status when the loan goes bad.
Which One You Get
Plan loans have to be repaid in substantially equal installments, at least quarterly, over no more than five years, with a longer term allowed for a loan used to buy a primary home.1Internal Revenue Service. Retirement Plans FAQs Regarding Loans Miss a payment and the loan enters technical default, but most plans give you a cure period to catch up. The IRS caps that cure period at the end of the calendar quarter following the quarter of the missed payment.2Internal Revenue Service. Issue Snapshot – Plan Loan Cure Period Individual plans can be stricter.
When the cure period expires without repayment, the split happens:
- If you’re still employed by the plan sponsor and no distributable event has occurred, the outstanding balance becomes a deemed distribution.
- If a distributable event has occurred, typically leaving your job, the plan terminating, or reaching normal retirement age, the plan can process a loan offset instead.
The trigger, not your preference, decides which label the plan applies. And the label controls everything that follows.
What a Deemed Distribution Actually Costs
The full outstanding loan balance gets added to your gross income for the year the cure period expires. A $15,000 defaulted balance lands on that year’s return as $15,000 of ordinary income. If you were under age 59½ at the time, an additional 10% early withdrawal penalty applies on top of your regular income tax.3Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts
Two features make this outcome particularly harsh. First, the underlying loan obligation is not extinguished. You owe the IRS taxes on money you never received in cash, and you still owe the debt to the plan. Second, a deemed distribution is not an eligible rollover distribution. You cannot move the amount into an IRA or another plan to avoid the tax.
Because no cash actually leaves the plan, the administrator does not withhold 20% for federal income taxes.4eCFR. 26 CFR 31.3405(c)-1 – Withholding on Eligible Rollover Distributions; Questions and Answers The entire tax burden falls on you, and if you don’t cover it through estimated payments or extra withholding, an underpayment penalty can follow.
If you do manage to repay the loan after it has been deemed distributed, the repayment doesn’t undo the tax already reported. It does create after-tax basis in your plan account, which the administrator tracks so those dollars aren’t taxed again when you eventually withdraw them.5GovInfo. 26 CFR 1.72(p)-1 – Loans Treated as Distributions
What a Loan Offset Actually Costs
A loan offset reduces your vested balance by the outstanding loan amount, and the debt is legally settled. The offset amount is taxable income in the year the offset happens, which could be years after you originally missed payments if the default sat dormant while you were still employed. The same 10% early withdrawal penalty applies if you’re under 59½.3Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts
Here’s the piece that changes the math: a loan offset is an eligible rollover distribution. You can contribute an equivalent amount of cash to an IRA or another qualified plan within the applicable rollover window and treat the offset as a tax-free rollover.6eCFR. 26 CFR 1.402(c)-2 – Eligible Rollover Distributions The cash has to come from outside the plan, since the plan assets were already used to settle the loan.
Mandatory 20% withholding only applies to cash or property you actually receive, so the offset amount itself is excluded.4eCFR. 26 CFR 31.3405(c)-1 – Withholding on Eligible Rollover Distributions; Questions and Answers If you also take a cash distribution of your remaining balance alongside the offset, the 20% withholding hits that cash portion.
The QPLO Rollover Deadline
Not every loan offset gives you the same amount of time to complete a rollover. A standard plan loan offset carries the usual 60-day rollover window.6eCFR. 26 CFR 1.402(c)-2 – Eligible Rollover Distributions A qualified plan loan offset, or QPLO, extends that deadline to your tax return filing due date for the year of the offset, including extensions.7Office of the Law Revision Counsel. 26 U.S. Code 402 – Taxability of Beneficiary of Employees Trust
To qualify as a QPLO, two conditions must be met: the loan had to be in compliance with federal rules immediately before the triggering event, and the offset must have occurred solely because you left your job or the plan terminated.7Office of the Law Revision Counsel. 26 U.S. Code 402 – Taxability of Beneficiary of Employees Trust A loan already in default before you separated doesn’t qualify, and that offset falls back to the 60-day window.
The QPLO extension is substantial. An offset in 2026, filed with an extension, could give you until October 2027 to come up with the replacement cash. That is often the difference between actually completing the rollover and defaulting to a taxable event.
How Each Shows Up on Form 1099-R
Both events are reported on Form 1099-R, and Box 7 tells you which one occurred.
A deemed distribution carries Code L in Box 7. The taxable amount appears in Box 1 and Box 2a; Box 4 (federal tax withheld) typically shows zero because no cash was distributed.8Internal Revenue Service. 2025 Instructions for Forms 1099-R and 5498 Code L can be paired with Code 1 or Code B when the early distribution penalty applies.
A regular plan loan offset is reported like any other distribution, without Code L. A qualified plan loan offset additionally receives Code M, which flags the extended rollover deadline.8Internal Revenue Service. 2025 Instructions for Forms 1099-R and 5498 If your 1099-R has Code M, you have until your return’s due date with extensions to roll it over.
The 10% early withdrawal penalty, when it applies, can be reported directly on Schedule 2 (Form 1040), line 8, if the standard rate applies to the full amount. If you qualify for an exception or need to calculate the penalty on a partial amount, file Form 5329 with your return.9Internal Revenue Service.

The Practical Differences at a Glance
- Trigger: Deemed distribution happens when the cure period expires and no distributable event has occurred, usually while you’re still employed. A loan offset requires a distributable event like separation or plan termination.
- When it’s taxed: Deemed distribution hits the year the cure period expires. A loan offset hits the year of the distributable event, which can be years later.
- The debt: A deemed distribution leaves the loan intact. A loan offset eliminates it.
- Rollover: A deemed distribution cannot be rolled over. A loan offset can, within 60 days, or by your filing deadline with extensions if it’s a QPLO.
- Withholding: Neither event triggers 20% withholding on the offset or deemed amount, because no cash leaves the plan for that portion. Withholding applies only to any separate cash distribution you receive alongside an offset.
- Future basis: Repaying a deemed-distributed loan creates after-tax basis in the plan. A rolled-over offset preserves the full tax-deferred balance in the receiving account.
For most people who leave a job with an outstanding loan, the offset is the more workable outcome because the rollover option exists. Find the replacement cash within the window and the tax consequence collapses to zero. With a deemed distribution, that door is closed from the start.
If You’re Called to Active Military Duty
One protection is worth knowing about because it can prevent a default from happening at all. If you’re called to active military service, your plan can suspend loan repayments for the duration of your service, and the interest rate during that period is capped at 6% if you provide a copy of your orders and specifically request the reduction. When you return, repayments resume at least at the pre-service frequency and amount, and the loan term is extended by the length of your service.10Internal Revenue Service.
