Yes, you can borrow against your 403(b), but only if your plan allows it and you meet specific conditions
Not every 403(b) plan permits loans. Your employer's plan document controls whether borrowing is an option at all. If your plan does allow loans, you can typically borrow up to 50% of your vested balance, with a maximum of $50,000. The loan comes from your own money — you are not borrowing from a lender — so you repay yourself with interest. The interest rate is usually set by your plan administrator, often at prime rate plus 1% or 2%.
The catch is that you must repay the loan within five years in most cases, through payroll deductions. If you leave your job before the loan is repaid, the entire remaining balance becomes due within a short window — often 60 to 90 days — or it is treated as a withdrawal and taxed as income plus a 10% early withdrawal penalty if you are under 59½.
Key Takeaways
- Your 403(b) plan must explicitly allow loans; check your plan document or ask your benefits administrator whether borrowing is available to you.
- You can typically borrow up to 50% of your vested balance, capped at $50,000, and must repay it within five years through payroll deductions.
- If you leave your job before repaying the loan, the unpaid balance is due within 60 to 90 days or becomes a taxable withdrawal with a 10% penalty if you are under 59½.
- Borrowing against your 403(b) reduces the money growing tax-deferred and can affect your retirement savings if you cannot repay on schedule.
How 403(b) loans work and what the limits are
A 403(b) loan is a loan to yourself. The money comes from your own account balance, not from a bank or credit card company. You set up a repayment schedule with your plan administrator, and the payments are deducted from your paycheck. Because the money stays within your 403(b), the interest you pay goes back into your account — you are not paying interest to an outside lender.
The IRS sets a standard loan limit: you can borrow the lesser of 50% of your vested balance or $50,000. If your vested balance is $100,000, you can borrow up to $50,000. If it is $60,000, you can borrow up to $30,000. Some plans set stricter limits, so check your plan document. The repayment period is usually five years, though some plans allow longer terms for loans used to buy a primary residence.
Your plan administrator sets the interest rate, which is typically the prime rate plus 1% to 2%. This rate is fixed for the life of the loan. You repay through payroll deductions, so the money comes out of your paycheck before taxes are calculated on it — the repayment itself is not taxed again.
What happens to your loan if you change jobs
This is the biggest risk of borrowing from your 403(b). If you leave your employer — whether you quit, are laid off, or retire — the loan becomes due when ready. Your plan administrator will give you a window, usually 60 to 90 days, to repay the entire remaining balance in full.
If you cannot pay it back within that window, the unpaid amount is treated as a withdrawal from your 403(b). That withdrawal is taxed as ordinary income in the year it happens. If you are under 59½, you also owe a 10% early withdrawal penalty on top of the income tax. For example, if you have $20,000 left to repay and you are 45 years old, that $20,000 becomes taxable income plus a $2,000 penalty — potentially $7,000 to $10,000 in taxes and penalties depending on your tax bracket.
Some plans offer a grace period or allow you to convert the loan to a rollover, but this varies widely. Before you take a loan, ask your plan administrator what happens if you leave the company and whether any options exist to avoid the when ready repayment demand.
The tax and retirement impact of borrowing
When you borrow from your 403(b), the money you borrow stops growing tax-deferred. If you borrow $30,000 and the market returns 7% annually, that $30,000 is not earning that 7% while it is out of the account. Over five years, that is roughly $5,000 to $7,000 in lost growth — money that would have been there for retirement but now is not.
The interest you pay back does go into your account and grows tax-deferred, so that is a partial offset. But the net effect is usually negative: you are paying interest to yourself at a rate lower than the market average, and you are missing out on market returns on the borrowed amount.
Additionally, if you borrow while still working, your paycheck is reduced by the loan repayment amount. This can affect your take-home pay and your ability to cover other expenses. If you then leave your job and cannot repay the loan, the tax bill can be substantial and arrive all at once.
Alternatives to borrowing from your 403(b)
Before taking a 403(b) loan, consider whether other options exist. A personal loan from a bank or credit union may carry a higher interest rate, but it does not jeopardize your retirement savings or create a tax bomb if you change jobs. A home equity line of credit, if you own a home, often has a lower rate than a personal loan and may be tax-deductible.
If you are facing a financial emergency, some 403(b) plans allow hardship withdrawals in addition to loans. A hardship withdrawal lets you take money out without repaying it, but you pay income tax and the 10% early withdrawal penalty if you are under 59½. This is usually worse than a loan, but it may be the only option if your plan does not allow loans or if you have already borrowed the maximum.
If you are considering a loan to pay off high-interest debt, calculate whether the 403(b) loan rate is actually lower than your current debt rate. If you are paying 18% on a credit card and can borrow from your 403(b) at 6%, the math favors the 403(b) loan — but only if you are confident you will stay in your job long enough to repay it.
How to request a 403(b) loan from your plan
Start by contacting your plan administrator or benefits department. Ask whether your plan allows loans and request a copy of the loan provisions in your plan document. This document will tell you the maximum you can borrow, the repayment term, the interest rate formula, and what happens if you leave your job.
If your plan allows loans, the administrator will provide a loan process. You will need to specify the amount you want to borrow and the repayment term. The administrator will calculate your maximum loan amount based on your vested balance and the plan's limits. Once you submit the process, approval typically takes one to two weeks.
After approval, you will sign a promissory note that outlines the repayment schedule, interest rate, and consequences of default. Repayment deductions will begin on your next paycheck or the next available pay period. Keep records of all loan statements and repayments — you will need them if you ever roll over the 403(b) to another plan or if there is a dispute about the loan balance.
Common mistakes to avoid when borrowing from your 403(b)
The biggest mistake is borrowing without a clear plan to repay before you leave your job. If there is any chance you might change employers within five years, think hard before taking a loan. The forced repayment or tax penalty can wipe out years of savings growth.
Another mistake is borrowing the maximum amount allowed. Just because you can borrow $50,000 does not mean you should. Borrow only what you need and can realistically repay on schedule. The smaller the loan, the less damage if your circumstances change.
A third mistake is ignoring the interest rate. Some plans charge prime plus 2%, others charge prime plus 1%. Over five years, that 1% difference adds up. Ask your administrator for the exact rate before you commit.
Finally, do not assume you can extend the repayment period if you run into trouble. Most plans have fixed five-year terms with no flexibility. If you fall behind on payments, the entire loan may become due when ready, triggering the same tax consequences as leaving your job.
Frequently Asked Questions
Can I borrow from my 403(b) if I am still paying off a previous loan?
Some plans allow multiple loans at the same time, but most limit you to one or two outstanding loans. Check your plan document or ask your administrator. Even if multiple loans are allowed, remember that each loan must be repaid within five years, so two loans mean two repayment schedules running simultaneously.
What if I repay my 403(b) loan early?
Most plans allow early repayment without penalty. Paying off the loan ahead of schedule reduces the total interest you pay and gets the full amount back into your account sooner to resume tax-deferred growth. There is no downside to early repayment.
Does borrowing from my 403(b) affect my credit score?
No. A 403(b) loan does not appear on your credit report because it is not a loan from an external lender. It does not help or hurt your credit score. However, if you leave your job and cannot repay the loan, the resulting tax bill could affect your finances if you owe the IRS money.
Can I borrow from my 403(b) while I am retired?
If you have already separated from service and are receiving distributions, most plans do not allow new loans. Loans are generally available only while you are still employed by the company sponsoring the plan. Check your plan document or ask your administrator about your specific situation.
What is the difference between a 403(b) loan and a hardship withdrawal?
A loan must be repaid; a hardship withdrawal does not. But a hardship withdrawal is taxed as income and subject to the 10% early withdrawal penalty if you are under 59½, while a loan is not taxed when you take it. A loan is usually the better option if your plan allows it, because you keep the money in your account and avoid the when ready tax hit.
