Question:
❓ You leave a job (whether you quit or got laid off) with a 401(k) loan you haven’t finished paying back. The loan was in good standing when you left. What actually happens to it?
A) You have 60 days to repay the whole loan or it gets taxed.
B) You have until your tax-filing deadline that year to move that amount into an IRA or new plan, or it’s taxed and penalized if you’re under 59½.
C) The loan is automatically forgiven once you leave.
D) Your new employer’s plan has to take over the loan.
✅ Answer: B)
You have until your tax-filing deadline that year to move that amount into an IRA or new plan, or it’s taxed and penalized if you’re under 59½.
Here’s why:
What happens to a 401(k) loan when you leave your job is that the plan settles it by subtracting the unpaid balance straight from your 401(k), so the loan is closed and you don’t keep owing your old employer a dime. The catch is that the amount they subtracted now counts as money pulled out of your retirement, which makes it taxable income, plus a 10% early-withdrawal penalty if you’re under 59½. To avoid all of that, you put an equal amount into an IRA or your new employer’s plan by your federal tax-filing deadline for that year, including any extension. A 2018 tax-law change gave you that whole window. Before then, you usually had just 60 days.
You’re not repaying the old loan—you’re replacing the amount. The loan is already gone. What’s left is coming up with that same dollar figure from your own money and moving it into a retirement account before the deadline, so it doesn’t count as a withdrawal. (This is for a loan that was current when you left.)
Here’s what a $9,000 unpaid loan looks like both ways, for someone under 59½ in the 22% federal tax bracket:
| What you do | Tax | 10% penalty | Total owed | Your retirement |
|---|---|---|---|---|
| Roll $9,000 into an IRA or new plan by the deadline | $0 | $0 | $0 | $9,000 stays invested |
| Miss the deadline (counts as a $9,000 withdrawal) | ~$1,980 | $900 | ~$2,880 (plus any state tax) | $9,000 gone for good |
And that $9,000 is gone for the long haul. You can only add money to a retirement account up to that year’s contribution limit, so there’s no writing a fat check later to make up the gap once the cash is back in hand. You lose the room AND every dollar of growth that $9,000 would have earned over the decades it had left to compound, which is almost always a bigger hit than the tax bill itself.
Why the others are not correct:
A) This was literally the rule for years, which is why it still feels right—you used to get 60 days to repay or it was taxed. The 2018 change replaced that short window with the longer tax-filing-deadline window, so the 60-day version is outdated.
C) Nothing gets forgiven. The balance doesn’t vanish—it comes out of your own retirement savings to close the loan, which is exactly why it can get taxed.
D) A new employer’s plan is never required to absorb your old loan. Some plans will accept a rollover of the amount, but that’s your move to make by the deadline, not something the new plan owes you.
Takeaway:
Treat that 401(k) loan balance like a clock that’s already running. Move the amount into an IRA or your new plan by your tax-filing deadline, and you keep every dollar working for you.
Changing jobs with a 401(k) loan is one of those moments where a missed deadline costs real money, and most people never even hear the clock start. Inside the TWC Network, you get access to financial professionals who walk you through the rollover, map the deadline to your actual situation, and make sure that balance lands back in a retirement account instead of becoming a surprise tax bill.
