401(k) Loan vs Personal Loan

A 401(k) plan loan is generally capped at the lesser of half the vested account balance or fifty thousand dollars. Standard loans must be repaid within five years through substantially level payments — in practice, payroll deduction — made at least quarterly; a loan used to buy a primary residence can extend to fifteen years. Not every plan offers loans at all, and where one does, the plan's own document sets some of these terms within the statutory ceiling rather than the statute dictating every detail.

Repaying a 401(k) loan means paying interest into your own retirement account rather than to a bank — the interest is not a pure cost the way a personal loan's is. This is real, but it is not the same as the loan being free: the repayments are made with after-tax dollars, and on a traditional 401(k) that money is taxed again on withdrawal in retirement — a mechanical double-taxation quirk of how the account works, separate from any question of whether borrowing was a good idea.

A rule still widely repeated says a departing employee has sixty days to repay an outstanding 401(k) loan before it is treated as a distribution. That has not been the law since the Tax Cuts and Jobs Act took effect for 2018: the actual deadline to repay the outstanding balance, or roll it over into another eligible retirement account, is now the due date of the individual's tax return for the year of separation — including any extensions actually filed, commonly pushing the real deadline into October of the following year rather than a matter of weeks. Sources still citing sixty days are describing a rule that has not applied for years.

If the outstanding loan balance is not repaid or rolled over by the extended deadline above, it is treated as a distribution: subject to ordinary income tax, and to an additional ten percent early-withdrawal penalty if the borrower is under fifty-nine and a half and no exception applies. This lands at the worst possible moment — the same event that ended the paycheck also creates a tax bill, without the cash from the original loan available to help pay it, since that money was already spent.

The comparison between a 401(k) loan and a personal loan is usually run assuming employment continues uninterrupted, which quietly assumes away the one risk that matters most for a worker whose ability to remain in the country is tied to that same job. An involuntary separation is not just an income shock for a visa holder — it can compound with an immigration-status clock running at the same time, at exactly the moment the loan-offset tax deadline above is also running. A personal loan carries no equivalent employment-linked trigger: its risk is the interest rate agreed at signing, not an event tied to the same job that could end for reasons entirely outside the borrower's control.
