457(b)

A 457(b) is a deferred compensation plan that lets eligible employees set aside part of their pay, before or after tax, for retirement. The name comes from the tax code section that governs it. What makes a 457(b) distinctive is the split between two very different versions of the same plan type: a governmental version, available to most state and local government employees, and a non-governmental "top hat" version, offered by some tax-exempt organizations to a narrow group of highly compensated employees. They share a name and a contribution limit, but not much else.

In a governmental 457(b), your contributions and any employer money are held in a trust for the exclusive benefit of participants, meaning the employer's general creditors can't reach it. You can generally roll a governmental 457(b) into an IRA or a new employer's retirement plan when you leave, and it can offer a Roth option and the standard catch-up contributions available to 401(k)s and 403(b)s.

A non-governmental 457(b), by contrast, is legally unfunded: the money you defer stays a general asset of the employer on paper, even though it's earmarked for you, and it's exposed to the employer's creditors if the organization becomes insolvent. Non-governmental plans generally cannot offer a Roth option, can't be rolled into an IRA, and typically must be paid out on a schedule tied to separation from service rather than left to grow indefinitely. The catch-up rules also differ: rather than the standard age-50 catch-up, eligible participants in a non-governmental 457(b) may instead access a "special" catch-up available only in the three years before the plan's normal retirement age, which can allow deferring up to double the standard limit in those years, based on unused contribution room from earlier years. Because the two plan types diverge in important ways, always check which version your employer offers before assuming a rule that applies to one applies to the other.

A genuinely distinctive 457(b) feature, shared by both versions: unlike a 401(k), 403(b), or IRA, a 457(b) has no 10% early-withdrawal penalty on distributions taken after you separate from service, regardless of your age. Ordinary income tax still applies, but the penalty that discourages early access to most other retirement accounts simply doesn't exist here.

A hypothetical example: Raj works for a state agency and defers $24,500 into his governmental 457(b) for 2026 — separately from the $24,500 he could also defer into a 403(b) if his employer offered one, since the two limits don't share the same cap. He leaves state government at 50 to take a private-sector job. Because 457(b) distributions after separation from service aren't subject to the 10% early-withdrawal penalty, he can access the money for a gap in employment without the penalty that would apply if the same amount sat in a 401(k).

Compare that to Wendy, a senior executive at a large nonprofit hospital system, who defers into the organization's non-governmental 457(b). Her balance technically remains a hospital asset until paid, so if the hospital were ever to face serious financial trouble, her deferred compensation could be at risk alongside other general creditors' claims — a risk that doesn't exist in a governmental plan or a typical 401(k).

Pros

• No 10% early-withdrawal penalty on distributions after separating from the employer, at any age.
• Governmental 457(b) contribution room is separate from a 401(k) or 403(b), so someone with access to both can potentially defer more in total.
• Governmental 457(b) money is protected in trust and portable to an IRA or new employer's plan.

Cons

• Non-governmental "top hat" 457(b) balances are exposed to the sponsoring employer's creditors and generally can't be rolled into an IRA.
• Non-governmental plans typically force a distribution schedule tied to separation from service, limiting flexibility to delay withdrawals.
• Fund menus and administration vary widely, and not every employer offers a match.
• The governmental-versus-non-governmental distinction is easy to overlook, and the rules genuinely differ — mixing them up leads to wrong assumptions about safety and flexibility.
