The difference between a 457 and a 403(b) comes down to who can join, when you can pull the money out without a penalty, and how safe the assets are from your employer’s creditors. Both plans let you defer $24,500 in 2026, but a governmental 457(b) lets you tap the balance without the 10% early withdrawal penalty as soon as you leave the job, at any age, while a 403(b) enforces the standard 59½ rule with only limited exceptions. The plans also handle employer contributions, catch-up rules, and rollovers differently, and one flavor of 457(b) exposes your savings to bankruptcy risk in a way no 403(b) does.
Who Each Plan Is For
A 403(b) is available to employees of public schools, colleges, universities, and organizations exempt from federal tax under IRC Section 501(c)(3), including non-profit hospitals, charities, and churches.1Internal Revenue Service. IRC 403(b) Tax-Sheltered Annuity Plans Ministers qualify too, including self-employed ones.
The 457(b) comes in two versions, and the distinction matters. A governmental 457(b) is offered by state and local governments, their agencies, and political subdivisions. A non-governmental 457(b) is offered by tax-exempt organizations that aren’t part of government, and participation is restricted to a select group of management or highly compensated employees.2Internal Revenue Service. Comparison of Tax-Exempt 457(b) Plans and Governmental 457(b) Plans
Some public sector employees — state university staff, public hospital workers — are eligible for both a 403(b) and a governmental 457(b) through the same employer. That opens up a planning move worth its own section below.
The Early Withdrawal Rule Is the Biggest Practical Difference
If early retirement is even a possibility, this is the decision driver.
A 403(b) follows the same withdrawal rules as a 401(k). Take money out before age 59½ and you owe ordinary income tax plus a 10% early distribution penalty. The main carve-outs: separating from service during or after the year you turn 55, total disability, or substantially equal periodic payments.3Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
A governmental 457(b) has no 10% early withdrawal penalty at all once you’ve separated from service, regardless of age.3Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Leave your government job at 45 and you can start drawing from the account immediately. You still owe income tax on every dollar, but skipping the 10% penalty on a $300,000 balance saves $30,000.
The advantage disappears if you roll a governmental 457(b) into an IRA or a 401(k). The money takes on the receiving account’s rules, including the pre-59½ penalty. If there’s any chance you’ll want early access, don’t roll a 457(b) into an IRA at job change.
2026 Contribution Limits and Employer Contributions
Both plans share the same base elective deferral limit for 2026: $24,500.4Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 That covers your combined pre-tax and Roth contributions to each plan.
The plans diverge on how employer money is treated. In a 403(b), employer matching or non-elective contributions don’t count against your $24,500 personal cap. They fall under a separate overall IRC Section 415(c) limit of $72,000 for 2026, which covers your deferrals and the employer’s contributions combined.5Internal Revenue Service. Application of IRC Section 415(c) When a 403(b) Plan Is Aggregated With a Section 401(a) Defined Contribution Plan Catch-up contributions don’t count toward that ceiling.
In a 457(b), employer contributions count against the same $24,500 annual limit as your own deferrals.6Internal Revenue Service. Retirement Topics 457(b) Contribution Limits If your employer contributes $5,000, you can only defer $19,500 of your own salary before hitting the cap. When employer contributions are generous, that’s a real constraint.
Each Plan Has a Catch-Up the Other Doesn’t
The standard age 50+ catch-up for 2026 is $8,000 on top of the $24,500 base, and it applies to both plans.4Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 For workers aged 60 through 63, a higher $11,250 “super catch-up” replaces the $8,000 amount in both plans.
The 403(b) 15-Year Service Catch-Up
If you’ve worked for the same qualifying employer for at least 15 years, a 403(b) lets you contribute an additional $3,000 per year, capped at $15,000 over your lifetime.7Internal Revenue Service. 403(b) Plans – Catch-up Contributions The actual annual amount comes out of a formula comparing your years of service against your cumulative past deferrals, with $3,000 as the ceiling. This stacks on top of 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.
The 457(b) Special Three-Year Catch-Up
In 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 contribution room from prior years.8Internal Revenue Service. Section 457(b) Plan of Governmental and Tax-Exempt Employers – Catch-up Contributions The exact amount is the lesser of twice the annual limit or the current year’s limit plus your unused room from earlier years.
You cannot use the special three-year catch-up and the age 50+ catch-up (or the super catch-up) in the same tax year. You pick whichever produces the larger contribution. With significant unused prior-year room, the special catch-up usually wins.
You May Be Able to Fund Both Plans
Contributions to a governmental 457(b) are not aggregated with contributions to a 403(b) for the annual deferral limit.9Internal Revenue Service. How Much Salary Can You Defer If You’re Eligible for More Than One Retirement Plan Each plan gets its own $24,500 cap. A state university employee eligible for both could defer up to $49,000 across the two plans in 2026 before any catch-ups.
Add catch-ups and the ceiling climbs further. A 62-year-old eligible for both could defer $24,500 plus $11,250 to each plan, for a combined $71,500. Layer the 15-year 403(b) catch-up on top and it goes higher still. Few people can save that aggressively, but the math is worth running in high-earning years near retirement.
Asset Protection and the Non-Governmental 457(b) Warning
How the assets are held decides what happens if your employer runs into trouble.
In a 403(b), plan assets sit in annuity contracts or custodial accounts holding mutual funds. Private-sector 501(c)(3) employers that actively manage the plan are generally subject to ERISA and its fiduciary protections; plans sponsored by public schools and churches are exempt from ERISA but still benefit from the trust or custodial structure that keeps assets separate from the employer.10Congressional Research Service. 403(b) Pension Plans: Overview and Legislative Developments
Governmental 457(b) assets must be held in trust for the exclusive benefit of participants under IRC Section 457(g).11Office of the Law Revision Counsel. 26 USC 457 – Deferred Compensation Plans of State and Local Governments and Tax-Exempt Organizations Your employer’s creditors can’t reach the money.
A non-governmental 457(b) works differently, and this is where people get hurt. The assets remain the property of the employer. They are not held in a protective trust. If the tax-exempt employer goes bankrupt, your retirement savings sit with the claims of the employer’s general creditors. Before deferring a dollar into any 457(b), confirm which type it is.
Rollovers and Portability
A 403(b) rolls broadly. You can move the balance 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) can also roll into an IRA, a 401(k), a 403(b), or another governmental 457(b). Remember the penalty trap: money that starts in the 457(b) is penalty-free on withdrawal after separation from service, and rolling it into an IRA or 401(k) ends that treatment.
A non-governmental 457(b) is the least portable of the three. It can generally only be rolled into another non-governmental 457(b), not into an IRA, a 401(k), or a 403(b).2Internal Revenue Service. Comparison of Tax-Exempt 457(b) Plans and Governmental 457(b) Plans Combined with the creditor exposure, that limited portability makes it the most restrictive of the three plan types.
Side-by-Side Comparison
- Eligibility. 403(b) covers public schools and 501(c)(3) non-profits. Governmental 457(b) covers state and local government employees. Non-governmental 457(b) is limited to select highly compensated employees of tax-exempt organizations.
- 2026 deferral limit. $24,500 for both. In a 457(b), employer contributions count against that cap. In a 403(b), they fall under a separate $72,000 ceiling.
- Early withdrawal penalty. 403(b) distributions before 59½ face a 10% penalty with limited exceptions. Governmental 457(b) distributions after separation from service carry no penalty at any age.
- Unique catch-ups. 403(b) offers a 15-year service catch-up of $3,000 per year, up to a $15,000 lifetime cap. Governmental 457(b) offers a three-year pre-retirement catch-up of up to double the annual limit.
- Asset protection. 403(b) and governmental 457(b) assets are held in trust or custodial accounts. Non-governmental 457(b) assets remain the employer’s property and are exposed in bankruptcy.
- Rollovers. 403(b) and governmental 457(b) roll into IRAs and most other qualified plans. Non-governmental 457(b) can only roll into another non-governmental 457(b).
- Dual participation. Employees eligible for both a 403(b) and a governmental 457(b) get separate deferral limits for each plan, potentially doubling annual tax-advantaged savings.
