What to Do With Your 403(b) After Leaving a Job: Rollovers and Penalties

When you leave a job, your 403(b) balance stays yours, and you have four choices for what to do with a 403(b) after leaving a job: leave it with the former employer, roll it into an IRA, roll it into your new employer’s retirement plan, or take it as cash. The right move depends on your age, your balance, whether you have an outstanding loan against the account, and how soon you might need the money. Picking wrong can cost thousands in taxes and penalties, so it’s worth understanding each path before you sign anything.

Leave It With Your Former Employer

Doing nothing is a real option, not a cop-out. If the plan has decent investment choices and reasonable fees, your balance keeps growing tax-deferred and you avoid the paperwork of a transfer. The account simply shifts from active to frozen: no new contributions or matches, but the investments keep working.

One thing can force your hand. Under the SECURE 2.0 Act, employers can push out former employees’ balances below $7,000 without asking. If your vested balance is between $1,000 and $7,000 and the plan uses this provision, the administrator can roll it into an IRA on your behalf automatically. Balances under $1,000 can be sent to you as a check. Above $7,000, the plan has to let you stay.

If you leave money behind, keep your mailing address and beneficiary designations current through the plan’s portal. Missing a 1099-R because the plan has your old address turns tax season into a scavenger hunt. You’re also stuck with whatever investment menu and fee structure the employer offers, and the employer can change either at any time.

Roll It Into an IRA

An IRA rollover is the most common post-separation move because it hands you full control over investments and fees. You can hold nearly any mutual fund, ETF, or individual stock instead of picking from a short employer-selected list. The mechanics matter, though, because a stumble can turn a tax-free transfer into a taxable event.

Direct Rollover Versus Indirect Rollover

A direct rollover, sometimes called a trustee-to-trustee transfer, moves the money straight from your 403(b) custodian to the IRA custodian. The check is made out to the new institution “for the benefit of” you, so the funds never pass through your hands. Nothing is withheld and nothing is reported as taxable income.¹

An indirect rollover puts the money in your hands first. The plan administrator must withhold 20% for federal income taxes before writing you the check.² You then have 60 days to deposit the full original amount into an IRA or other eligible plan.³ That means finding the withheld 20% out of your own pocket to complete the rollover; otherwise the missing chunk counts as a taxable distribution and, if you’re under 59½, gets hit with the 10% early withdrawal penalty. You do get the withheld money back at tax time, but only as a credit against what you owe. Direct rollovers sidestep this whole trap, which is why almost every advisor recommends them.

Rolling to a Roth IRA

You can roll a traditional (pre-tax) 403(b) into a Roth IRA, but the entire converted amount becomes taxable income in the year of the transfer.⁴ That can pencil out if you’re in a low-income year between jobs and expect a higher bracket later. A Roth 403(b) rolls into a Roth IRA with no tax owed, since you already paid on those contributions. The nontaxable portion of a Roth 403(b) has to move by direct trustee-to-trustee transfer.

What You Give Up by Rolling to an IRA

An IRA rollover has one downside that catches people off guard: you lose the Rule of 55. If you’re between 55 and 59½ and might need penalty-free access to the money, keep it in the employer plan until you’re sure you won’t. More on that below.

Roll It Into Your New Employer’s Plan

If your new job offers a 401(k), 403(b), or governmental 457(b), you can roll the old 403(b) directly into it.⁴ Consolidation keeps things simple, and it preserves the Rule of 55 protection an IRA rollover would strip away. The catch: the new plan has to accept incoming rollovers, and not all do. Ask HR or the plan administrator before you start.

The paperwork mirrors a direct IRA rollover. Get the new plan’s account details, complete the distribution form from the old plan, and specify a trustee-to-trustee transfer. The trade-off is that you’re back inside an employer-chosen investment menu, which may or may not beat what you had.

Cash It Out

Taking the money as cash is almost always the worst option, but sometimes the situation demands it. Here’s what actually happens.

The plan withholds 20% of the taxable portion for federal income taxes before sending anything.² That 20% is a prepayment, not the full bill. The whole distribution gets added to your income for the year, which can push you into a higher bracket. If you’re under 59½ and don’t qualify for an exception, the IRS adds a 10% early withdrawal penalty on top of the income tax.⁵ State income tax may hit too.

Run the numbers on a $40,000 balance. The administrator sends you $32,000 after withholding $8,000. If you’re in the 22% federal bracket and owe the 10% penalty, your federal tax bill is $12,800. The $8,000 already withheld leaves you owing another $4,800 at tax time, plus whatever the state takes. And that’s before the decades of compound growth you gave up.

The 10% Early Withdrawal Penalty and the Exceptions That Matter

Take money out of a 403(b) before 59½ and the IRS adds a 10% penalty on top of ordinary income tax.⁵ Several exceptions can spare you the penalty, though income tax still applies to pre-tax money:

Rule of 55: If you separate from service during or after the calendar year you turn 55, you can withdraw from that employer’s 403(b) penalty-free. Only works if the money stays in the employer plan. Roll it to an IRA and the exception is gone.⁵
Substantially equal periodic payments: A series of roughly equal annual withdrawals based on your life expectancy, sometimes called 72(t) distributions. Once you start, you must continue for at least five years or until 59½, whichever is later.
Disability: Total and permanent disability removes the penalty.
Death: Beneficiaries who inherit the account don’t owe it.
Medical expenses: Withdrawals up to the amount of unreimbursed medical expenses over 7.5% of your adjusted gross income.
Qualified domestic relations order: Payments to a former spouse under a court-ordered QDRO in a divorce.
IRS levy: The penalty doesn’t apply when the IRS levies the account.
Birth or adoption: Up to $5,000 per parent for qualified expenses within a year of a child’s birth or adoption.
Military reservists: Certain reservists called to active duty for at least 180 days.

The Rule of 55 deserves extra attention because it turns directly on the choice you’re making right now. People who retire or get laid off between 55 and 59½ often roll everything to an IRA out of habit, then find they’ve locked themselves out of penalty-free withdrawals for years. If there’s any chance you’ll need the money before 59½, think hard about where it lives.

If You Have an Outstanding 403(b) Loan

Borrowed against your 403(b) and still owe? The remaining balance typically comes due immediately or within a short grace period set by the plan. When the unpaid amount gets deducted from your account, the IRS calls it a “plan loan offset” and treats it as a distribution.⁶

You can roll the offset amount into an IRA or another eligible plan to avoid the tax. Because the offset happened when you left the job, it counts as a “qualified plan loan offset,” and the rollover deadline runs to your tax return due date, including extensions, for the year of the offset.⁷ So a job left in 2026 gives you until October 15, 2027 (with an extension) to deposit cash equal to the loan offset into an IRA.

Skip the rollover and the offset is taxable income for the year, plus the 10% penalty if you’re under 59½. This is the surprise tax bill that catches people the following spring. Find the payoff amount right away and decide whether you can cover it or need to plan for the tax hit.

Picking the Right Move

The decision comes down to a few clean questions. Under 55 and don’t need the money? A direct rollover to an IRA or your new employer’s plan keeps the savings tax-sheltered and gives you better flexibility. Between 55 and 59½ with a chance you’ll tap the funds? Keep them in the employer plan to preserve the Rule of 55. Over 59½? Any option is penalty-free, so the choice comes down to investment quality and fees.

Whatever you pick, decide on purpose. The worst outcome isn’t the second-best choice. It’s ignoring the account until the plan forces you out, an outdated address costs you tax forms, or a small loan balance quietly becomes a large tax bill.
