Are 401(k) Loans Taxed?

Not if you pay the loan on time

What Is a 401(k) Loan?

A 401(k) loan is money borrowed against a 401(k) retirement savings plan. Borrowing from your own 401(k) will not affect your credit and does not require a credit check, as the remaining assets in the account are used for collateral. For plans that allow loans, the loan must be repaid, with interest, within a prescribed time frame.

Key Takeaways

  • Some employers allow participants to borrow against their 401(k) account, but there are limits on how much.
  • A 401(k) loan will not affect the borrower's credit and does not require a credit check.
  • If you default on the loan you will pay income taxes on the money withdrawn and may also be subject to an early withdrawal penalty.
  • Depending on the plan, a borrower may not be able to make contributions if they have a loan outstanding.

How a 401(k) Loan Works

For critical short-term needs, borrowing from a 401(k) account can be a better choice than a hardship withdrawal, which is allowed in certain circumstances, or a high-interest bank loan. Any money borrowed from a 401(k) account is tax-exempt, as long as you pay back the loan on time. And you're paying the interest to yourself, not to a bank.

You do not have to claim a 401(k) loan on your tax return. As long as the loan is paid back in a timely manner, the interest attached to certain plans is the only tax consequence. The term "interest" is a bit misleading because the funds go back into the participant's own account.

The borrower must use after-tax dollars to repay the loan, including interest. This means the government taxes a portion of it twice—income tax is paid on the amount again when the borrower taps the account in retirement. However, 401(k) interest rates are typically modest so double taxation has a negligible impact. It is only significant when the amount borrowed is large and is repaid over several years.

The IRS allows loans of $50,000 or 50% of your vested balance, whichever is less. An exception is when the vested balance is less than $10,000. In that case, you may be allowed to borrow as much as $10,000, provided the vested account value is at least $10,000. Each plan has its own limits for loans and is not required to offer them at all, so check with your employer for specifics.

On March 27, 2020, former President Trump signed a $2 trillion emergency relief package. It doubled the amount of 401(k) money available as a loan to $100,000, waived the 50% of balance limitation, and dropped the early-withdrawal penalty if you default before age 59½.

As an example (under the traditional rules), if your vested balance is $15,000, you can borrow $10,000 because 50% is only $7,500. However, if your balance is $120,000, the maximum you can borrow is $50,000. With the introduction of the CARES Act, you would be able to borrow $100,000 of that $120,000 but only if your income was affected by the crisis.

Defaulting on a 401(k) Loan

The tax consequences are significant for borrowers who default on a 401(k) loan. Except in 2020 for the crisis-affected, those younger than 59½ years old will be subject to a 10% early withdrawal penalty in addition to paying income taxes on the outstanding balance.

Let's say you are younger than 59½, default on a loan with a $10,000 outstanding balance, and have an effective tax rate of 15%. By the time you file your annual tax return, you will owe the government $1,000 for the early-withdrawal penalty and another $1,500 in income tax (which would otherwise be deferred until retirement). Within one year, that $10,000 is down to $7,500.

401(k) Loan Risks

Some plans do not allow participants to make plan contributions if they have a loan outstanding. If you take five years to repay the loan, you will save nothing to your 401(k). That also means that will not benefit from the tax advantages of making payments to your retirement account.

You will also miss out on any matching contributions that your employer might provide while you are paying off the loan.

401(k) Loan vs. Withdrawal

It is important to determine your ability to repay a 401(k) loan before proceeding. Most planners advise keeping your nest egg intact unless, for example, you can no longer pay your rent or mortgage, utility bills, or groceries.

In short, if you need funds and are confident you can pay the loan back, the minimal tax consequences and ability to pad your account with interest can make these loans a viable option.
