What is the difference between a 403(b) and a 457 plan?

Both are tax-advantaged retirement savings plans, but a 403(b) is available to employees of public schools and certain nonprofits, while a 457(b) is available to state and local government employees (including school staff). The key practical difference is in early withdrawal rules: 457 plans do not impose the 10% early-withdrawal penalty before age 59½ that 403(b) plans do.

Can teachers contribute to both a 403(b) and a 457 at the same time?

Yes, if your employer offers both plans. Each plan has its own contribution limit, so contributing to both effectively doubles your tax-advantaged savings capacity.

What are the 2024 contribution limits for 403(b) and 457 plans?

For 2024, the base contribution limit is $23,000 for each plan, plus an additional $7,500 catch-up if you are 50 or older. If you have both plans, you can contribute up to $23,000 to each — $46,000 total (or $61,000 with catch-up on both).

Should I prioritize my 403(b) or my 457?

It depends on your situation. If you may need access to funds before age 59½, the 457 is more flexible because it does not have the 10% early-withdrawal penalty. If your employer matches contributions to one plan, prioritize that one first. Many educators choose to max out one before contributing to the other.

403(b) vs 457 Plan — What Educators Need to Know

What are 403(b) and 457 plans?

Both are tax-advantaged retirement savings accounts that let you set aside money from your paycheck before taxes (traditional) or after taxes (Roth), and invest it for retirement. They sit alongside your pension — your pension provides a baseline, and these plans let you save beyond it.

403(b) — available to employees of public schools, colleges, and certain nonprofits. Sometimes called a Tax-Sheltered Annuity (TSA).
457(b) — available to state and local government employees, including many school-district staff. Often called a deferred-compensation plan.

How are they the same?

In most day-to-day ways, 403(b) and 457 plans feel identical:

Both offer pre-tax (traditional) and Roth contribution options.
Both have the same annual contribution limit — $23,000 in 2024, plus a $7,500 catch-up contribution if you are 50 or older.
Both grow tax-deferred (or tax-free for Roth contributions).
Both are funded through payroll deductions, making saving automatic.

How are they different?

The most important practical difference is about early access:

With a 403(b), withdrawals before age 59½ generally incur a 10% early-withdrawal penalty on top of income taxes (with limited exceptions).
With a 457(b), there is no 10% early-withdrawal penalty — you only pay ordinary income tax. This makes the 457 more flexible if you retire or separate from service before 59½.

Other differences are more technical: 403(b) plans may offer annuity contracts, and some have a special 15-year catch-up for long-tenured employees. 457 plans have their own special catch-up provision in the three years before your plan's normal retirement age.

Can I contribute to both at the same time?

Yes, if your employer offers both. Because each plan has its own separate contribution limit, contributing to both effectively lets you save up to $46,000 per year ($23,000 + $23,000 in 2024) — or $61,000 if you're 50+ and use catch-up contributions on both.

This dual-plan strategy is one of the most powerful tools available to educators who want to accelerate retirement savings.

Which one should I prioritize?

There is no single right answer, but here are common guidelines:

If your employer offers a match on one plan, contribute enough to capture the full match first.
If you might retire before 59½ or want penalty-free flexibility, lean toward the 457.
If you're focused on maximizing total savings, fund one to its limit, then start on the other.
If you want Roth options, check whether both plans offer Roth — not all do.

What about Roth 403(b) and Roth 457?

Both plans may offer a Roth option, where you contribute after-tax dollars and qualified withdrawals (including growth) are tax-free. The trade-off is no upfront tax deduction. A Roth option can be valuable if you expect to be in a higher tax bracket in retirement, or if you want tax-free income alongside your pension.

How do these fit with my pension?

Think of your retirement income as having layers: your pension provides a predictable base, and a 403(b) and/or 457 builds on top of it. Together, they can give you income flexibility, help cover healthcare costs, and provide a cushion for the unexpected.
