What Is the Difference Between a 457 and a 403(b)?

The difference between a 457 and a 403(b) comes down to five things: who qualifies, how early withdrawals are taxed, how employer contributions count against your limit, what catch-up provisions you can use, and how well the money is protected from your employer’s creditors. Both plans share a $24,500 elective deferral limit for 2026, and both are built for public sector and non-profit workers, but the governmental 457(b) has one feature a 403(b) can’t match: if you leave your job before 59½, you can withdraw from it without the 10% early distribution penalty.¹

Who Qualifies for Each Plan

A 403(b) is for employees of public schools, colleges and universities, and organizations exempt from federal tax under IRC Section 501(c)(3), including non-profit hospitals, charities, and churches.² Ministers qualify as well, including self-employed ministers.

The 457(b) comes in two very different forms. A governmental 457(b) is sponsored by a state or local government, its agencies, or a political subdivision. A non-governmental 457(b) is sponsored by a tax-exempt employer that isn’t part of government, and participation is restricted to a select group of management or highly compensated employees.³ The two versions share a name and little else; the protections and portability discussed below apply only to the governmental version unless noted.

Many public employees qualify for both a 403(b) and a governmental 457(b) through the same job. State university staff, public hospital workers, and some school district employees are common examples. Dual eligibility is a planning advantage because the contribution limits don’t aggregate.

The Early Withdrawal Rule That Changes Everything

If early retirement is on the table, this is the distinction that matters most.

A 403(b) follows the same early withdrawal rules as a 401(k). Take money out before 59½ and you owe ordinary income tax plus a 10% penalty. Narrow exceptions exist for separation from service in or after the year you turn 55, total disability, and substantially equal periodic payments.¹ Outside those, early access is expensive.

A governmental 457(b) carries no 10% early withdrawal penalty after separation from service, at any age.¹ Leave your government job at 45 and you can start drawing on the account right away. Income tax still applies to every dollar, but skipping the 10% penalty on a $300,000 balance keeps $30,000 in your pocket.

One trap to know about: the penalty-free treatment is tied to the 457(b) account itself. Roll the balance into an IRA, a 401(k), or a 403(b), and the money picks up the receiving plan’s rules, including the 10% penalty before 59½. If there’s any chance you’ll need the funds early, think hard before consolidating a governmental 457(b) into another account type when you change jobs.

2026 Contribution Limits and How Employer Money Counts

Both plans allow an elective deferral of $24,500 for 2026, covering the combined total of pre-tax and Roth contributions.⁴ The treatment of employer contributions is where they split.

In a 403(b), employer matching or non-elective contributions don’t count against your personal $24,500 cap. They sit under a separate overall limit of $72,000 for 2026 under IRC Section 415(c), which covers both your deferrals and the employer’s contributions combined.⁵ Catch-up contributions sit outside that $72,000 ceiling.

In a 457(b), employer contributions share the same annual limit as your own deferrals.⁶ If your employer puts $5,000 into your governmental 457(b), the most you can defer from your own paycheck is $19,500 before you hit the $24,500 cap. For employees with generous employer contributions, that’s a real constraint.

Catch-Up Contributions

The standard age 50 catch-up for 2026 is $8,000 in both plans, raising the personal deferral ceiling to $32,500.⁴ From there, each plan offers something the other doesn’t.

The 403(b) 15-Year Service Catch-Up

If you’ve worked at least 15 years for the same qualifying employer, a 403(b) lets you contribute an extra $3,000 per year, capped at $15,000 over your lifetime.⁷ The amount available in a given year depends on a formula comparing your service and your past deferrals, but $3,000 is the annual ceiling. It stacks on the age 50 catch-up. A 55-year-old teacher with 20 years in the same district could defer up to $35,500 in 2026 ($24,500 + $8,000 + $3,000).

The Governmental 457(b) Special Three-Year Catch-Up

In each of the three years immediately before your plan’s designated normal retirement age, a governmental 457(b) lets you contribute up to double the standard limit, as much as $49,000 in 2026, if you have enough unused room from prior years.⁸ The actual figure is the lesser of twice the annual limit or the current year’s limit plus whatever you didn’t use in earlier years.

You can’t use the special three-year catch-up and the age 50 catch-up in the same tax year. You pick whichever is larger, and for anyone with meaningful unused prior-year room, the three-year catch-up usually wins.

The Super Catch-Up at Ages 60 Through 63

Starting in 2025, participants aged 60, 61, 62, or 63 get a higher catch-up limit. For 2026 that figure is $11,250 instead of $8,000, and it applies to both 403(b) and governmental 457(b) plans.⁴ A 61-year-old in a 403(b) could defer up to $35,750, or $38,750 if the 15-year catch-up also applies. In a governmental 457(b), you still can’t combine the super catch-up with the special three-year catch-up; you take the larger one.

Running Both Plans at the Same Time

Contributions to a governmental 457(b) don’t aggregate with contributions to a 403(b) for purposes of the annual deferral limit.⁹ Each plan has its own $24,500 cap. A state university professor eligible for both could defer up to $49,000 across the two in 2026 before any catch-up.

Catch-ups make the ceiling higher still. A 62-year-old eligible for both plans could in theory put $35,750 into a 403(b) and $35,750 into a governmental 457(b) for a combined $71,500, and the 15-year catch-up would push that further on the 403(b) side. Few workers can save at that level, but for high earners in their final working years the arithmetic is worth doing.

Where the Money Sits, and Who Can Reach It

In a 403(b), assets are held in annuity contracts or custodial accounts invested in mutual funds. Private 501(c)(3) employers that actively manage their plans are generally subject to ERISA fiduciary rules; public school and church plans are ERISA-exempt but still use the trust or custodial structure that keeps assets separate from the employer.¹⁰

In a governmental 457(b), assets must be held in trust for the exclusive benefit of participants under IRC Section 457(g).¹¹ The employer’s creditors can’t touch the money.

A non-governmental 457(b) is different, and this is where participants get hurt. The assets remain the property of the employer. They are not held in a protective trust. If the tax-exempt employer files for bankruptcy, your retirement savings sit with the employer’s general unsecured creditors. That exposure is the central trade-off of a non-governmental 457(b), and it’s why eligibility is restricted to a small group of management or highly compensated employees. Before deferring anything into a 457(b) outside of government, confirm which type of plan your employer sponsors.

Rollovers When You Change Jobs

A 403(b) rolls broadly: into an IRA, a 401(k), another 403(b), or a governmental 457(b). Direct trustee-to-trustee transfers avoid withholding complications.

A governmental 457(b) rolls into the same destinations, with the caveat already noted. The penalty-free early withdrawal treatment stays only while the money remains in a 457(b). Roll it into an IRA or a 401(k) and the receiving account’s early withdrawal rules apply.

A non-governmental 457(b) is far less portable. It can generally only be rolled into another non-governmental 457(b), not into an IRA, 401(k), or 403(b).³ Combined with the creditor risk, that makes the non-governmental 457(b) the least flexible of the three plan types.

Required Minimum Distributions

Both plans require minimum distributions in retirement. Under SECURE 2.0, participants born between 1951 and 1959 begin RMDs the year they turn 73; those born in 1960 or later can wait until the year they turn 75. The first distribution is due by April 1 of the year after you reach the applicable age. Some plans allow participants still working past that age to delay distributions until actual retirement, and the specifics vary between 403(b) and 457(b) plans, so check your plan document.

The Roth Catch-Up Mandate Coming in 2027

Starting in 2027, catch-up contributions to 401(k), 403(b), and governmental 457(b) plans must be made on a Roth basis if your FICA wages from the sponsoring employer were above $145,000 the prior year.¹² That threshold is indexed for inflation. Workers under it can still make pre-tax catch-up contributions.

The IRS issued final regulations in 2025 setting mandatory compliance for taxable years beginning after December 31, 2026, though plans may adopt the rule earlier under a good-faith reading of the statute. For high earners currently making pre-tax catch-ups, the practical effect is that catch-up money will stop reducing current taxable income. The offset is tax-free growth and qualified withdrawals later.
