How Does 401(k) Loan Repayment Work After You Leave Your Job?

Updated July 9, 2026 6 min read

Payroll deduction makes a 401(k) loan feel almost invisible while it’s being repaid — the money is taken out before it ever reaches a checking account. Leaving the job that set up that convenience is where the real complexity begins.

The short answer

Once someone leaves the employer sponsoring the plan, payroll deductions for a loan stop, but the loan itself doesn’t disappear. Under current tax rules, former employees generally have until the tax filing deadline for that year, including extensions, to repay the remaining balance in full or roll the amount into an IRA or new employer’s plan. Missing that deadline typically means the unpaid balance is treated as a taxable distribution.

Why the deadline changed over the years

Older versions of these rules gave departing employees a much shorter window — often just 60 or 90 days — to repay a loan after leaving. Current tax law extended that window considerably for what’s treated as a qualified plan loan offset, giving people until their tax return is due, including extensions, for the year the separation occurred. Because deadlines and thresholds like this are set by the government and can change, anyone in this situation should confirm the current rule rather than relying on older information.

Ways to actually repay the balance

Consequences of missing the deadline

If the balance isn’t resolved in time, it’s usually treated as a loan offset rather than a simple missed payment, which has its own tax reporting through Form 1099-R. The amount becomes taxable income, and if the person is under the age set by the government for penalty-free withdrawals, an early withdrawal penalty may apply as well. This can be a meaningful, unplanned tax bill, especially if the loan balance is large relative to income.

What to weigh when leaving a job with an open loan

Someone changing jobs with an outstanding plan loan generally needs to think through cash flow — is there enough available to pay off the balance directly, or would rolling the offset into an IRA using other savings make more sense — well before the tax deadline arrives. It also helps to get the exact offset amount and deadline in writing from the plan administrator rather than estimating, since interest may continue to accrue on the unpaid balance up to the point it’s actually settled.

A practical habit

Anyone leaving a job with a 401(k) loan still open benefits from confirming the exact balance and deadline with the plan immediately, rather than waiting until tax season to sort it out. Because the repayment window is tied to a tax filing deadline that can shift with extensions, treating it as a fixed calendar date to plan around — not a vague future concern — tends to prevent it from becoming a surprise tax bill.
