401(k) Loans Before Rollover: The Default-on-Separation Trap
If you leave a job with an outstanding 401(k) loan, you have a narrow window to repay it before it becomes a taxable distribution with a 10% penalty.
If you leave a job with an outstanding 401(k) loan you cannot repay, the plan declares a "loan offset": the unpaid balance is treated as a taxable distribution, and if you are under 59½ a 10% early withdrawal penalty applies on top. You can still erase that tax hit by depositing cash equal to the offset into an IRA or eligible employer plan by your tax-filing deadline for that year, including extensions.
What a Loan Offset Is
Most plans treat an outstanding loan as due in full the moment you separate. Grace periods vary by plan document, often 60 days or until the end of the calendar quarter.
If you cannot repay in time, the plan reduces your account by the loan amount, issues a 1099-R, and reports the offset as taxable income. A $40,000 loan balance becomes $40,000 of ordinary income.
The Extended Deadline, and What It Actually Requires
Under the Tax Cuts and Jobs Act of 2017 (IRC Section 402(c)(3)(C)), if the offset arises from separation from service or plan termination, you have until the due date of your federal return for the offset year, including extensions, to make a rollover contribution equal to the offset amount. For most people that is October 15 of the following year.
The key phrase is "equal to the offset amount." The loan itself is gone; the plan already closed it. To avoid the tax and penalty, you deposit your own cash into a traditional IRA or eligible employer plan within the window. The 1099-R arrives either way; you report the offset and claim the rollover exclusion once completed.
When the Trap Bites Hardest (and When It Doesn't)
It bites hardest when someone is laid off unexpectedly, has no liquid savings to fund the rollover, and never learns the extended deadline exists. It also catches people who take the maximum loan ($50,000 or 50% of the vested balance, whichever is less) and change jobs without a repayment plan.
It matters less if you are 59½ or older (income tax still applies, but the penalty disappears), if you have savings to deposit before the deadline (the offset becomes a paperwork event), or if the balance is small enough that simply paying the tax is the simpler choice.
Before leaving, check the Summary Plan Description for when the loan comes due; some plans accept repayment by direct check within 90 days of separation, the cheapest path.
How This Connects to Your 401(k) Rollover Decision
A loan offset does not block a rollover of the rest of your vested balance; the loan runs on its own clock and lands on that year's taxable income.

Frequently Asked Questions
Does the TCJA extension apply if I defaulted on the loan while still employed?
No. The extended deadline applies only to loan offsets caused by separation from service or plan termination; a mid-employment default falls under the old 60-day window.
Can I roll over the loan balance itself to an IRA?
No. Once the plan executes the offset, the only fix is depositing your own cash, up to the offset amount, into a qualifying account.
What if I cannot come up with the cash by October 15?
The offset remains taxable income, plus the 10% penalty if you are under 59½. There is no further extension.
Can I repay the loan directly to the plan after I leave instead of doing a rollover?
In most cases no; plans typically stop accepting payments once you separate. The practical path is the rollover-equivalent deposit to an IRA.
What to Do Next
What decides this for you. Whether you have a loan outstanding against the plan on the day you leave. That is the whole trigger. The balance stops being a loan the moment you separate and becomes an offset, which the IRS treats as a distribution.
Where it goes wrong. Everyone assumes a missed loan payment is a credit problem. It is a tax problem. The unpaid balance becomes ordinary income, plus 10% if you are under 59½, and to avoid that you have to deposit the full outstanding amount into an IRA yourself. Not the payments you had left. The entire balance, in cash, at the exact moment you have stopped receiving a paycheck. The 2017 rules extended the deadline to your tax filing date including extensions, which sounds generous until you notice the plan document may impose something far shorter, and the plan document wins. A $40,000 balance for someone in the 32% bracket at age 54 costs roughly $16,800 in tax and penalty, over money they already spent.
Worth a conversation if you have a loan outstanding and a job change on the horizon, or you have already separated and the offset has not been resolved. The order in which you handle the loan and the rollover decides the cost. Book a call.
