You can borrow from your 403(b), but only under specific circumstances

Yes, you can borrow money from your 403(b) balance without triggering the early withdrawal penalty — but the rules are strict. The IRS allows loans from 403(b) plans, and if you follow the repayment terms, you won't owe the 10% penalty that normally applies to withdrawals before age 59½. However, you must repay the loan on schedule, and if you don't, the unpaid balance becomes a taxable withdrawal.

The key difference between a loan and a withdrawal is that a loan is money you're borrowing from yourself with an obligation to pay it back. Your plan administrator sets the terms, and you make regular payments just like you would to a bank. If you miss payments or leave your job before the loan is repaid, the remaining balance can be treated as a distribution, which means taxes and possibly penalties explore.

Key Takeaways

  • A 403(b) loan lets you borrow up to 50% of your vested balance (or $50,000, whichever is less) without the 10% early withdrawal penalty.
  • You must repay the loan within five years in regular installments, or the unpaid balance becomes taxable income.
  • If you leave your job, your plan may require you to repay the entire loan within 60 to 90 days or face taxes and penalties on the remaining balance.
  • Interest rates on 403(b) loans are set by your plan and are typically lower than bank loans, but you pay interest to yourself.
  • Not all 403(b) plans offer loans, so you need to check your plan documents or contact your plan administrator first.

How much you can borrow from your 403(b)

The IRS limits 403(b) loans to the lesser of two amounts: 50% of your vested account balance or $50,000. Your vested balance is the money in your account that you fully own — some employers require you to work a certain number of years before you own the full amount you've contributed.

For example, if your vested balance is $80,000, you can borrow up to $40,000 (50% of $80,000). If your vested balance is $120,000, you still can only borrow $50,000 because that's the IRS cap. The plan administrator calculates your vested balance and tells you the maximum loan amount you're allowed to take.

Some plans also have their own rules that are stricter than the IRS limits. Your employer might require a minimum loan amount (such as $1,000) or allow you to borrow only a percentage lower than 50%. Check your plan documents or ask your administrator what the actual limits are for your specific plan.

Repayment terms and what happens if you don't repay

You must repay a 403(b) loan within five years in substantially equal installments, usually through payroll deduction. Your plan sets the interest rate, which is typically the prime rate plus 1% to 2%, though rates vary by plan. You're paying interest to your own account, so that money goes back into your retirement savings.

If you stop making payments or miss a payment, the loan goes into default. The unpaid balance is then treated as a distribution — meaning you owe income tax on it at your regular tax rate, and if you're under 59½, you also owe the 10% early withdrawal penalty. This can be a significant tax bill, so it's important to understand the repayment obligation before you take the loan.

If you leave your job, your employer's plan typically requires you to repay the entire remaining loan balance within 60 to 90 days. If you don't repay it by the important date, the unpaid amount becomes a taxable distribution. Some plans may allow you to extend the repayment period, but this varies — contact your plan administrator to find out what happens in your situation.

The difference between a loan and a hardship withdrawal

A 403(b) loan is different from a hardship withdrawal, which is a one-time withdrawal for specific financial emergencies. A hardship withdrawal doesn't have to be repaid, but it is subject to income tax and the 10% penalty (unless you're over 59½ or meet another exception). Hardship withdrawals are also limited to the amount needed to cover the hardship, and your plan must deny the withdrawal if you have other resources available.

A loan is better than a hardship withdrawal if you can repay it, because you avoid the 10% penalty and keep more money in your retirement account. However, if you can't commit to repaying the loan on schedule, a hardship withdrawal might be the only option — though you'll pay taxes and penalties on the amount withdrawn.

Tax implications of a 403(b) loan

While you're repaying the loan, you don't owe income tax on the money you borrow — it's your own money. However, the interest you pay on the loan is not tax-deductible, even though it goes back into your retirement account. This is different from a home equity loan, where interest is sometimes deductible.

When you repay the loan, the principal goes back into your 403(b) account tax-free. The interest portion also goes back into your account, but you paid it with after-tax dollars. This means you're essentially paying tax on the interest twice: once when you earn the money to pay the interest, and again when that interest grows and is eventually withdrawn in retirement.

If the loan goes into default or you don't repay it by the important date when you leave your job, the unpaid balance becomes a taxable distribution. You'll receive a Form 1099-R showing the distribution amount, and you'll owe income tax on it. If you're under 59½, you'll also owe the 10% penalty unless you roll the amount into another retirement plan within 60 days.

How to request a 403(b) loan from your plan

Contact your plan administrator — usually your employer's benefits or human resources department — and ask whether your plan allows loans. Not all 403(b) plans offer this option, so this is your first step. If loans are available, the administrator will give you a loan process and explain the terms specific to your plan.

The process typically asks for the loan amount you want to borrow, the reason for the loan, and how you plan to repay it. Some plans require you to provide documentation of a financial hardship, while others allow loans for any reason. The administrator reviews your request and either approves or denies it.

Once approved, the loan is funded — usually within a few days to a couple of weeks. Repayment typically begins the month after you receive the loan. You'll make payments through payroll deduction, and your pay stub will show the loan payment amount. Keep track of your loan balance and remaining repayment term so you know when the loan will be paid off.

What to consider before taking a 403(b) loan

A 403(b) loan can be a lower-cost way to borrow money compared to a credit card or personal loan, but it has real risks. If you leave your job or can't repay the loan, you face a large tax bill. You're also reducing the amount of money growing for your retirement, which means less money available when you retire.

Before you borrow, ask yourself whether you can commit to repaying the loan on schedule, even if your job situation changes. If you're considering leaving your job in the next few years, a loan may not be the right choice because you'll have to repay it quickly or face taxes and penalties. If you can't repay it within five years, a loan isn't the right tool for your situation.

Consider other options first: a personal loan from a bank, a credit card with a 0% introductory rate, or borrowing from family. These alternatives might cost more in interest, but they don't put your retirement savings at risk or create a tax liability if your circumstances change.

Frequently Asked Questions

What happens to my 403(b) loan if I get fired or laid off?

Your plan typically requires you to repay the entire remaining loan balance within 60 to 90 days. If you don't repay it by the important date, the unpaid amount becomes a taxable distribution, and you'll owe income tax plus the 10% penalty if you're under 59½. Some plans may allow you to roll the loan into another retirement plan to avoid the penalty, so contact your administrator when ready if this happens.

Can I take out more than one 403(b) loan at the same time?

Most plans allow only one loan at a time, though some allow two loans if you meet certain conditions. The total amount you can borrow across all loans is still limited to 50% of your vested balance or $50,000, whichever is less. Check your plan documents or ask your administrator what the rules are for your specific plan.

Do I have to pay taxes on the interest I pay on a 403(b) loan?

No, you don't pay income tax on the interest itself. However, you pay the interest with after-tax dollars (money you've already paid income tax on), so you're paying tax on the income that funds the interest payment. The interest goes back into your account and grows tax-deferred, but when you withdraw it in retirement, you'll owe tax on it then.

Can I pay off my 403(b) loan early without a penalty?

Yes, most plans allow you to repay the loan early without any penalty. Paying it off early reduces the amount of interest you pay and gets the money back into your retirement account sooner. Contact your plan administrator to find out the process for making an early repayment.

What if I can't repay my 403(b) loan because of a financial hardship?

If you're struggling to make loan payments, contact your plan administrator when ready. Some plans offer loan forbearance or allow you to extend the repayment period, though this varies. If you can't work out a repayment arrangement, the unpaid balance will be treated as a distribution and you'll owe taxes and penalties on it.
