What Is a 457(b) Retirement Plan and How Does It Work?

A 457(b) retirement plan is a tax-deferred savings account offered by state and local governments and certain tax-exempt organizations. You contribute pre-tax pay (or after-tax Roth dollars, if your plan allows), the money grows tax-deferred, and in 2026 you can defer up to $24,500 of your salary, with higher limits available if you qualify for a catch-up. The plan’s signature advantage: once you separate from your governmental employer, distributions are not subject to the 10% early withdrawal penalty that applies to 401(k) and 403(b) withdrawals before age 59½.¹

Who Can Participate

Your employer decides whether you have access, and the type of employer determines which flavor of 457(b) you get. The IRS recognizes two categories: governmental and non-governmental.²

Governmental 457(b) plans are sponsored by state, county, and municipal governments, including public school districts and state universities. Employees who perform services for the government employer can generally participate.³

Non-governmental 457(b) plans are offered by tax-exempt organizations that are not churches, such as hospitals, charities, and nonprofit foundations. Eligibility is much narrower. To avoid federal funding and reporting requirements, these plans must be limited to a select group of management or highly compensated employees. There is no fixed dollar cutoff for that group; the Department of Labor and the courts look at how many workers are eligible relative to the whole workforce, salary gaps between eligible and ineligible employees, and whether the eligible employees have bargaining power over their pay.⁴

If a nonprofit offers you a 457(b), you are likely considered a key employee. If your employer is a government body, the plan is generally open to the broader workforce.

Governmental vs. Non-Governmental: How Your Money Is Protected

This distinction matters more than any other feature of the plan.

Governmental 457(b) plans must hold all assets in a trust or custodial account for the exclusive benefit of participants.³ Your balance is separated from the employer’s finances, so if your government employer faces a budget crisis, the money in your account is out of reach of its creditors.

Non-governmental 457(b) plans are unfunded. The assets technically remain the property of the employer until they are distributed to you.³ If the sponsoring nonprofit goes bankrupt, your balance can be seized by its creditors, and you stand in line as an unsecured creditor of the organization. That risk deserves serious thought before you funnel large sums into a non-governmental plan, especially if your employer’s financial health is anything less than solid.

Contribution Limits for 2026

The standard elective deferral limit is $24,500 in 2026.⁵ That cap applies to the total of all your contributions across every 457(b) plan you participate in. And unlike a 401(k) or 403(b), which have a separate, higher combined limit that includes employer contributions, the 457(b) cap covers your deferrals and any employer contributions together.⁶

Three catch-ups can push the limit higher.

Age 50 Catch-Up

If you are in a governmental 457(b) and reach age 50 by year-end 2026, you can add $8,000 on top of the standard limit, for a total of $32,500.⁵ This catch-up is not available in non-governmental plans.

Enhanced Catch-Up for Ages 60 Through 63

Starting in 2025, a higher catch-up applies to governmental 457(b) participants who are 60, 61, 62, or 63. For 2026, it is $11,250 instead of $8,000, bringing the total possible deferral to $35,750.⁵ Once you turn 64, you drop back to the regular $8,000.

Special Three-Year Catch-Up

Both governmental and non-governmental 457(b) plans can offer a provision no other retirement plan matches. During the three years before you reach the plan’s stated normal retirement age, you can contribute up to double the standard annual limit. For 2026, that is up to $49,000.⁷

The catch: you can only use this to the extent you have unused deferral room from earlier years. The actual limit is the lesser of double the annual amount ($49,000) or the standard limit ($24,500) plus your total underused deferrals from prior years in the plan.⁸ If you maxed out every year, this catch-up adds nothing.

You cannot combine the age 50 catch-up and the special three-year catch-up in the same year. If you qualify for both, the plan applies whichever produces the larger contribution.⁷

Stacking a 457(b) with a 401(k) or 403(b)

This is one of the plan’s most underappreciated features. The 457(b) contribution limit is independent of the limits for 401(k) and 403(b) plans.⁶ If your employer offers both a 403(b) and a governmental 457(b), you can defer up to $24,500 into each in 2026, for $49,000 in combined deferrals before any catch-ups.

The IRS explicitly excludes 457(b) plans from the combined deferral calculation across other plan types.⁹ Teachers, university employees, and state workers with access to both a 403(b) and a 457(b) can effectively double their annual tax-advantaged savings.

Roth 457(b) Contributions

Many governmental 457(b) plans now include a designated Roth option. You pay income tax on Roth contributions going in, but qualified withdrawals in retirement come out tax-free, growth included.¹⁰

The dollar limits are the same whether you contribute pre-tax, Roth, or a mix. There is no income cap on Roth 457(b) contributions, unlike a Roth IRA.¹⁰ Any employer match on your Roth deferrals goes into a separate pre-tax account.

One SECURE 2.0 wrinkle worth flagging: beginning in 2026, if your FICA-taxable wages from the sponsoring employer exceeded $150,000 the prior year, any catch-up contributions you make must be designated as Roth. If your plan does not offer a Roth option, you lose the ability to make catch-ups at all.

Getting Money Out

Distributions from a 457(b) are generally tied to specific events: leaving the sponsoring employer, reaching the required minimum distribution age of 73, disability, death, or an unforeseeable emergency (a narrow hardship exception for severe financial crises caused by things like illness, accident, or casualty loss).¹¹

The signature benefit is the exemption from the 10% early withdrawal penalty. Money pulled from a 401(k) or 403(b) before age 59½ generally faces that 10% federal tax on top of ordinary income tax. Governmental 457(b) distributions do not, regardless of your age, as long as you have separated from service.¹ Non-governmental 457(b) distributions are also exempt from the penalty.

One trap catches people off guard: if you roll money into your 457(b) from a 401(k), 403(b), or IRA, withdrawals of those rolled-in dollars before age 59½ do trigger the 10% penalty.¹² Only money that originated in the 457(b) keeps the penalty-free treatment. Think carefully before consolidating other retirement accounts into your 457(b) if you plan to tap it early.

Traditional pre-tax 457(b) distributions are taxed as ordinary income in the year you receive them, with federal income tax withheld as if they were wages. You must begin RMDs by April 1 of the year after you turn 73 or the year after you separate from service, whichever comes later.¹³

Rollovers

Governmental 457(b) plans offer broad rollover flexibility. After separation, you can move your balance into a traditional IRA, Roth IRA, 401(k), 403(b), SEP-IRA, or another governmental 457(b).¹⁴ A direct rollover to a pre-tax account avoids immediate tax. Rolling into a Roth IRA triggers income tax on the transferred amount now, in exchange for tax-free qualified withdrawals later.

Non-governmental 457(b) plans are far more restrictive. You cannot roll a non-governmental 457(b) into an IRA, 401(k), or 403(b). The only option is a direct plan-to-plan transfer to another non-governmental 457(b), and both plans must permit it. Limited portability is another reason to keep contributions to a non-governmental plan in proportion to your comfort with the employer’s long-term stability.

How the 457(b) Compares to a 401(k) and 403(b)

The three plans share the same $24,500 baseline deferral for 2026, but the 457(b) diverges in ways that matter:

Governmental 457(b) distributions after separation are penalty-free at any age. Withdrawals from a 401(k) or 403(b) before 59½ generally cost an extra 10%.¹
You can max out a 457(b) and a 401(k) or 403(b) in the same year. Contributions to one do not eat into the limit for the other.⁹
The special three-year catch-up up to double the standard limit has no equivalent in a 401(k) or 403(b).⁷
All 401(k) and 403(b) plans hold assets in trust. Non-governmental 457(b) assets are exposed to the employer’s creditors.³
In a 401(k), employer matches do not count against your personal deferral limit. In a 457(b), employer and employee contributions share the same cap.⁶

For public-sector employees who might retire before 59½, or anyone with access to both a 457(b) and a second employer plan, those differences translate into real flexibility and real money.
