Does a 401k Loan Count as Income or Stay Tax-Free?

A 401(k) loan does not count as income for tax purposes, as long as it meets the requirements in Section 72(p) of the Internal Revenue Code and you keep up with the repayment schedule. The money is legally a loan against your own retirement savings, not a withdrawal, so it skips both income tax and the 10% early-distribution penalty. That protection lasts only while the loan stays in compliance. If it falls out of compliance or you default, the IRS reclassifies the outstanding balance as a taxable distribution.¹

The Rules That Keep the Loan Out of Your Taxable Income

Section 72(p) starts from the position that any loan from a qualified retirement plan is a taxable distribution. You only escape that default treatment if your loan satisfies every requirement in the statute. Miss one, and the full amount is taxable the moment it is disbursed.¹

The maximum you can borrow is the lesser of $50,000 or half your vested account balance. The $50,000 cap is not static. It is reduced by the difference between your highest outstanding loan balance during the past 12 months and your current loan balance, which prevents anyone from paying off a loan and immediately re-borrowing to reset the cap.²

There is a small-balance floor. If your vested balance is under $20,000, you can borrow up to $10,000 even though that exceeds the 50% limit. Someone with a $15,000 balance could borrow up to $10,000 rather than being capped at $7,500.³

Three structural requirements apply to every loan. The loan must require full repayment within five years. Payments must be substantially equal over the life of the loan, with installments due at least quarterly. And there must be a legally enforceable written note setting out the amount, term, and interest rate.⁴

The one exception to the five-year rule is a loan used to buy your principal residence. In that case the plan can allow a longer repayment period. The statute sets no maximum term for residence loans; the plan document controls, and terms of 15 to 30 years are common.⁴

The interest rate must be comparable to what a commercial lender would charge for a similarly secured loan.⁵ In practice most plans charge prime plus 1%, fixed at origination.

When the Loan Does Become Taxable Income

A 401(k) loan turns into taxable income when it stops meeting the statutory requirements. The two most common triggers are missed payments and leaving your job. A loan that violated the rules at the start, such as one that exceeded the borrowing limit or ran longer than five years for a non-residence purpose, is treated as a taxable distribution in the year the violation occurs.¹

Missed Payments

If you miss a scheduled payment, many plans allow a cure period. The maximum permitted cure period runs through the last day of the calendar quarter following the quarter in which the payment was due. Miss a payment due in February, and you would have until June 30 to catch up. If you do not make up the missed payment plus accrued interest by the end of the cure period, the entire outstanding balance becomes a deemed distribution and is added to your taxable income for that year. Plans are not required to offer a cure period; some treat a missed payment as an immediate default.⁶

Leaving Your Job

Termination, layoff, or resignation often accelerates the repayment timeline. Many plans require full repayment within 60 to 90 days after separation. If you cannot repay by the plan’s deadline, the plan typically offsets your account balance by the unpaid amount, triggering a loan offset distribution that lands on your tax return unless you roll it over in time.

Deemed Distribution vs. Loan Offset

This distinction matters because only one of them can be rescued with a rollover.

A deemed distribution happens when you default on the loan while still employed and the plan cannot legally pay out your balance. The IRS treats the outstanding balance as a distribution for tax purposes, but the plan does not actually reduce your account. You still owe the loan, and the balance stays on the plan’s books. A deemed distribution cannot be rolled over into an IRA or another plan.²

A loan offset is different. The plan actually reduces your account balance to pay off the loan, which requires a distributable event such as leaving your job. Because it is a real distribution, a loan offset is eligible for rollover. You can deposit an equivalent amount of cash into an IRA within the rollover window and avoid the tax hit entirely.⁷

One footnote on deemed distributions: after one occurs, you can still make late repayments on the loan. Those payments increase your tax basis in the plan, which reduces the tax you owe on future withdrawals.²

Rolling Over a Loan Offset to Keep It Out of Your Income

If you leave your job and the plan offsets your account to repay the outstanding loan, you have a window to roll that amount into an IRA and owe nothing. The deadline depends on the type of offset.

For a standard loan offset, the usual 60-day rollover rule applies. You have 60 days from the date of the offset to deposit cash equal to the offset amount into an eligible retirement plan.⁷

A qualified plan loan offset, or QPLO, gets a much longer window. A QPLO occurs when the offset is triggered specifically by your separation from employment or the plan’s termination, and the loan was in compliance immediately before that event. The Tax Cuts and Jobs Act extended the rollover deadline for a QPLO to your tax filing due date for that year, including extensions. An offset in 2026, with an extension filed, could leave you until October 2027 to complete the rollover.⁷

The practical difficulty is that a loan offset is not a cash distribution. The plan zeroes out the loan by reducing your account balance, so no check arrives. To roll it over you have to come up with the cash from another source and contribute it to your IRA. That is often hard right after a job loss, but the tax savings on a $20,000 or $30,000 offset make it worth the effort.

What a Default Actually Costs

Whether a default produces a deemed distribution or a loan offset, the plan administrator reports it to the IRS on Form 1099-R. You will receive a copy and need to include the taxable amount as ordinary income on your return for the year the default occurred.⁷

If you are under age 59½ when the default happens, the IRS adds a 10% additional tax for early distribution on top of the regular income tax.⁸

The combined cost adds up fast. A $20,000 default for someone in the 24% federal bracket means $4,800 in income tax plus a $2,000 early-withdrawal penalty, for a federal bill of $6,800 before any state income tax. A loan offset rolled over within the deadline, by contrast, owes nothing.

Things the Plan Controls, Not the Tax Code

Federal law permits 401(k) plans to offer loans but does not require them to. Whether your plan allows borrowing, how many loans you can have at once, and whether early payoff is available are all set by the plan document.²

If your plan is subject to qualified joint and survivor annuity rules, which many defined-contribution plans have waived but some retain, you need your spouse’s written consent before taking a loan. The consent window runs for either 90 or 180 days before the loan is secured, depending on which regulatory framework the plan follows.⁹

One advantage over outside borrowing: a 401(k) loan does not appear on your credit report. Plan administrators do not report loan activity to credit bureaus, so taking a loan or even defaulting will not directly affect your credit score. The tax bill from a default can still create financial pressure that reaches your credit indirectly if you cannot pay it.
