457(b) vs. 403(b) for Nurses: Which Account Can You Use Before 59½?

Nurses often hold both a 403(b) and a 457(b), and the two follow different rules before age 59½. A governmental 457(b) generally carries no 10% additional tax on early withdrawals, while a 403(b) generally does unless an exception applies. Rolling either account into an IRA can change the answer.

This guide builds on our overview of nurse retirement planning. It focuses on one question that comes up when a nurse thinks about stepping back before 65: which account can you draw from first, and what does each one cost to use?

Which type of 457(b) do you have?

There are two kinds. A governmental 457(b) is offered by state and local governments, such as a county hospital or public health system. A tax-exempt 457(b) is offered by non-governmental tax-exempt employers and is limited to select management or highly compensated employees. The rules differ, so confirm the type before relying on any of them.

The mix depends on your employers. A nonprofit hospital may offer a 403(b). A government-run hospital may offer a governmental 457(b), and sometimes a pension. The IRS publishes a side-by-side comparison of the two 457(b) types. The table below combines it with the IRS list of exceptions to the 10% additional tax.

The plan document controls what is available. Some plans pay out only a lump sum, and some do not allow partial withdrawals.

Can you withdraw from a 457(b) before 59½ without the 10% additional tax?

From a governmental 457(b), generally yes. The IRS says its distributions are not subject to the 10% additional tax, except for amounts rolled in from another type of plan or an IRA. Income tax still applies. The plan decides when you can take money, often after you leave the employer.

The IRS lists the events that can make a governmental 457(b) distributable: leaving the employer, reaching age 59½ while still working (if the plan allows it), an unforeseeable emergency, plan termination, a qualified domestic relations order and small accounts. Required distributions begin later, as with other plans.

Can you withdraw from a 403(b) before 59½ without the 10% additional tax?

Generally not, unless an exception applies. The one nurses ask about most is separation from service: if you leave the employer in or after the year you turn 55, withdrawals from that employer’s 403(b) may avoid the 10% additional tax, if the plan allows them. A 72(t) series is another route. Income tax still applies.

The separation exception looks at one employer at a time. A 403(b) from a hospital you left earlier generally does not qualify, and neither does money already moved to an IRA. Our Rule of 55 guide explains who qualifies and which accounts it reaches.

How can a 457(b) work as a bridge before 59½?

Because a governmental 457(b) may be reached after you leave the employer with no 10% additional tax, some households weigh it as an early source of cash before 59½, while leaving a 403(b) or IRA untouched. That choice has trade-offs: the money is still taxable income, and it uses the same pre-tax dollars.

Here is what to weigh before relying on it:

• Income tax and brackets. Pre-tax withdrawals add to taxable income, which can affect Marketplace premium credits before Medicare.
• Plan rules. A plan may pay only a lump sum, which can create a large income year.
• What the money was meant for. Dollars spent early are not available later, when other accounts carry more of the load.
• Pension timing. A pension that starts on a fixed date can fill bracket room in the same years.

Our answer on health insurance before 65 covers the coverage side, and our answer on pension lump sum or monthly income covers pension choices.

What happens if you roll a 457(b) into an IRA?

Once a governmental 457(b) is rolled into an IRA, the IRA rules apply. Withdrawals before 59½ are then subject to the 10% additional tax unless an exception fits, so the 457(b) feature is generally lost. The reverse matters too: money rolled into a governmental 457(b) from another plan type or an IRA remains subject to it.

A tax-exempt 457(b) works differently. The IRS comparison shows it cannot be rolled into an IRA or other plan, so payout choices may be set by the plan’s own terms. Ask the plan administrator what elections you have, and when they must be made, before your last day. A rollover generally cannot be undone, so talk to your CPA first.

What does the Rule of 55 mean when you have both accounts?

The Rule of 55 looks at one employer’s plan at a time. A 403(b) at the hospital you leave in or after the year you turn 55 may be reachable without the 10% additional tax, if the plan allows it. A governmental 457(b) generally does not need the rule. An earlier employer’s 403(b), or an IRA, generally falls outside it.

For nurses who changed hospitals, that sorts accounts into three groups: those that may be reachable at 55 or later, those that are generally reachable after leaving the job with no 10% additional tax, and those that may need another route. The sort comes first, before any rollover. Our guide to what to do with your 401(k) when you retire covers the broader choices.

What might a hypothetical nurse couple weigh?

A hypothetical couple would list each account by type and employer, then ask which can be reached before 59½, what each would cost in tax, and which rollover would end a feature. This is a hypothetical illustration for education only. It is not a projection or a recommendation for any household.

Imagine a nurse who leaves a county hospital at 57. At the county hospital she has a governmental 457(b) and a pension. Years earlier, at a nonprofit hospital, she had a 403(b) that she rolled into an IRA. Her spouse is still working and has employer health coverage. The couple would ask what the pension pays and when, whether the governmental 457(b) could cover some years of spending, and what the IRA allows without the 10% additional tax. They would also ask what the income from each source does to their tax bracket and coverage costs. The map shows which account fits which years.

What mistakes do nurses make with 457(b) and 403(b) accounts?

Most mistakes come from assuming that two accounts with similar names follow the same rules. They do not, and a rollover done early can end a feature that was not yet needed. These are the ones we would check for first.

• Assuming a 457(b) works like a 403(b). The 10% additional tax treatment differs, and the IRS statement on 457(b) plans is for governmental plans.
• Rolling a governmental 457(b) into an IRA before using it. The IRA’s rules then apply.
• Rolling other money into a governmental 457(b). Rolled-in amounts remain subject to the 10% additional tax.
• Forgetting an old account. A 457(b) or 403(b) from a former employer may be sitting unused.
• Not asking about payout options. A plan may allow only a lump sum, which can create a large income year.
• Skipping beneficiary forms. A spouse may not know which accounts exist or who is named.
• Treating the Rule of 55 as an all-account rule. It generally covers the plan of the employer you just left.

What are the limits and risks?

Avoiding the 10% additional tax is not the same as avoiding income tax, and plan rules vary by employer. Results depend on individual circumstances. Each benefit described here has a limit, and a rule that fits one nurse may not fit another. These are the limits to weigh.

• Income tax still applies. Pre-tax withdrawals are ordinary income, and large years can reach higher brackets or Medicare premium tiers two years later.
• Plan terms vary. A plan may restrict partial withdrawals, charge fees, or require a lump sum.
• Early withdrawals reduce a portfolio that may need to last decades. Money taken at 57 has more years to fund. See our guide to sequence of returns risk.
• Rollovers are hard to reverse. A decision that closes a door is final once it is processed.
• Health coverage is a separate cost before 65. Withdrawals can affect premium credits.
• Tax-exempt 457(b) rules differ. Confirm the plan type and ask the administrator.
• Rules change. Confirm current IRS rules before acting.

How does your CPA fit in?

Your CPA prepares and files your return and can confirm how each withdrawal is reported and taxed. The retirement income side of the plan supplies the list of accounts by type, the order of withdrawals and the dates that change income, such as a pension start.

Bring your CPA into the conversation before you give notice at the hospital, not after. A rollover or a payout election made on your last day is hard to adjust.

What should you do next?

Which accounts you can use, and in what order, depends on facts in your own plan documents: the employer type, the plan type and what each plan allows. A good first step is a list of every employer you have worked for and the account each one offered. That is the first step of the Retirement Triage work we describe on our page for nurses.
