Short answer: if your employer offers both a 403(b) and a governmental 457(b), the 457(b) wins on flexibility — no 10% early-withdrawal penalty after you leave the job, and a separate limit that lets you double your annual savings. The 403(b) wins on employer matching and rollover freedom. For most public-sector workers, the best answer is both: up to $49,000 combined in 2026 ($65,000 if you are 50 or older).
Contribution limits: identical, but separate
A 403(b) serves public schools, nonprofits, churches, and hospitals; a 457(b) serves state and local government workers, plus select nonprofit executives — and many public-sector workers qualify for both plans at once.
For 2026, the IRS set the employee elective deferral limit at $24,500 for both plans, up from $23,500 in 2025. Workers age 50 or older can add an $8,000 catch-up ($32,500 total), and workers ages 60 to 63 get a larger “super” catch-up of $11,250 ($35,750 total).
The critical difference is how the limits interact. A 403(b) limit is shared with a 401(k): you cannot max out both. A 457(b) limit is separate from both, so an employee with access to both plans can defer $24,500 to the 403(b) and another $24,500 to the 457(b) in the same year.
Verified example: a 52-year-old teacher with access to both plans contributes the maximum to each — $24,500 plus the $8,000 age-50 catch-up in each plan:
- 403(b): $32,500
- 457(b): $32,500
- Combined total: $65,000 in tax-deferred savings for the year
A private-sector worker with a single 401(k) tops out at $32,500 — the dual-plan employee saves exactly twice as much. Our 457 calculator can model what those contributions grow to.
The catch-up rules that set them apart
Each plan has its own special catch-up. The 403(b) 15-year rule lets you add $3,000 per year, up to a $15,000 lifetime maximum, after 15 years of service with the same employer, on top of the regular limit and the age-50 catch-up. The 457(b) special 3-year catch-up lets you contribute up to double the annual limit — $49,000 in 2026 — in the three years before your plan’s normal retirement age, limited to amounts you underused in earlier years. You cannot stack it with the age-50 catch-up in the same year. The 457(b) catch-up is the more powerful of the two for late-career savers who started late, but not every employer offers it.
Early withdrawals: the 457(b)’s biggest advantage
This is the difference that changes retirement timing. Withdrawals from a 403(b) before age 59½ generally trigger a 10% penalty on top of income tax, with limited exceptions (including separation from service in the year you turn 55 or later). A $20,000 early 403(b) withdrawal at age 50, with no exception applying, costs $2,000 in penalties alone.
A governmental 457(b) has no 10% penalty at all once you separate from service, at any age. A firefighter or teacher who retires at 52 can draw on the 457(b) immediately, penalty-free, and leave the 403(b) untouched until 59½ — making the 457(b) the natural bridge account for early retirement.
One warning: this applies to governmental 457(b) plans. Non-governmental 457(b) plans have their own distribution restrictions, and their assets legally remain the employer’s property until paid out, leaving them exposed to creditors.
Employer contributions, Roth options, and rollovers
Employer match: 403(b) plans commonly offer a match; 457(b) plans usually do not. If your employer matches 403(b) contributions, capture the full match before funding anything else. Note that employer contributions to a 457(b) count against the same $24,500 limit, while 403(b) employer contributions fall under a separate $72,000 ceiling for 2026. Roth option: many 403(b) plans offer a Roth option, and some governmental 457(b) plans now do as well — see our guide to Roth vs traditional 401(k). Rollovers: a 403(b) and a governmental 457(b) both roll freely into IRAs and other eligible plans; a non-governmental 457(b) generally rolls only into another non-governmental 457(b).
Which plan wins for you?
- Employer match available: fund the 403(b) up to the match first, always.
- Retiring before 59½: prioritize the 457(b) after the match — penalty-free access after separation beats a better fund menu.
- Saving more than $24,500 a year: use both plans. The separate 457(b) limit is the biggest advantage public-sector workers have.
- Within three years of retirement and under-saved: ask about the 457(b) special catch-up — it can nearly double your final years of contributions.
- Working for a nonprofit (not a government): weigh the 403(b)’s trust protection and rollover freedom against the non-governmental 457(b)’s creditor risk.
The strongest play for most dual-eligible workers: 403(b) up to the match, then 457(b) up to its limit, then back to the 403(b) for anything left over. If you are still deciding how much to save, read our guide on how much to save for retirement by age.

Frequently asked questions
Can I contribute to both a 403(b) and a 457(b) at the same time?
Yes, if your employer offers both. The IRS treats their limits separately, so in 2026 you can defer up to $24,500 to each — $49,000 combined, or $65,000 combined if you are 50 or older and use both catch-ups. A 403(b) limit is shared with a 401(k), but the 457(b) limit stands alone.
Does a 457(b) have an early withdrawal penalty?
A governmental 457(b) imposes no 10% penalty once you separate from service, regardless of age, though you still owe income tax. A 403(b) generally charges the 10% penalty before 59½ unless an exception applies, such as separation in the year you turn 55.
What is the 457(b) special catch-up?
In the three years before your plan’s normal retirement age, a governmental 457(b) may let you contribute up to twice the annual limit — $49,000 in 2026 — capped at unused room from prior years. You cannot combine it with the age-50 catch-up in the same year, and not every employer offers it.
Is a non-governmental 457(b) safe?
It carries a risk a 403(b) or governmental 457(b) does not: the money legally remains the employer’s property until paid to you, so creditors can reach it in bankruptcy. It also generally cannot roll into an IRA or another employer’s plan.
