Specifically, you usually can’t deduct interest on 401(k) or 403(b) plan loans if any of the balance comes from elective deferrals. Let’s say your plan loan is secured by your 401(k) or 403(b) account balance. If any of that balance is from your elective deferrals, you can’t deduct any of the interest.

Does the interest I pay on a 401k loan go to me?

The loan will have interest attached to it. While that interest payment does go back into your account, consider the opportunity cost of what you could have earned if the loan amount was invested.

Is 401k loan double taxed?

First the loan repayments are made with after-tax income (that’s once) and, second, when you take those payments out as a distribution at retirement you pay income tax on them (that’s twice). So yes, you pay twice. The taxation is exactly the same whether you borrow from your 401k or from another source.

Is the interest on a 401k loan tax deductible?

Loan interest is generally not tax deductible (unless the loan is secured by your principal residence). In most cases, the amount you borrow is removed from your 401 (k) plan account, and your loan payments are credited back to your account.

How are you taxed when you borrow from your 401k?

Another myth is that when you borrow from your 401k, you are being taxed twice because you’re paying the loan back with after-tax money. But in truth, only the interest part of the repayment is treated that way.

What happens when you pay yourself interest on a 401k loan?

In other words, the net result of “paying yourself interest” via a 401(k) loan is not that you get a 5% return, but simply that you end out saving your own money for yourself at a 0% return – because the 5% you “earn” in the 401(k) plan is offset by the 5% of loan interest you “pay” from outside the plan!

Why are 401k loans considered tax inefficient?

The claim is that 401 (k) loans are tax-inefficient because they must be repaid with after-tax dollars, subjecting loan repayment to double taxation. Only the interest portion of the repayment is subject to such treatment.
