403(b) vs 457(b) for Nurses 2026

Part of the Nurse Money Hub — retirement accounts, Roth strategies, and nurse FIRE in one map.

Many hospital and academic-medical-center nurses have access to both a 403(b) and a 457(b). They look almost identical on the enrollment page — both let you defer pre-tax income for retirement — but they behave very differently when you actually want to touch the money, and one of them carries a risk the other doesn't. Understanding the difference lets you stack them and shelter more than $46,000 a year.

What each account is

A 403(b) is the non-profit and public-sector cousin of the corporate 401(k). Hospitals, universities, and public health systems offer it, often with an employer match. It works exactly the way you'd expect: you defer income pre-tax (or Roth, if offered), it grows tax-deferred, and you pay ordinary income tax on withdrawals in retirement.

A 457(b) is a "deferred compensation" plan offered by government employers and some non-profits. It also lets you defer income pre-tax, but it lives under a different section of the tax code — and that's where the meaningful differences come from.

The contribution limits stack

Here's the part that makes having both so powerful: the 403(b) and 457(b) have separate contribution limits that do not share a cap. In 2026 each has an employee-deferral limit in the low-to-mid $20,000s (the IRS adjusts these annually for inflation), plus catch-up contributions if you're 50 or older. Because they're separate buckets, a nurse who can afford it may contribute the full amount to the 403(b) and the full amount to the 457(b) in the same year — roughly doubling the pre-tax space available compared with a single plan.

The early-access difference

This is the deciding factor for many nurses. With a 403(b), pulling money out before age 59½ generally triggers a 10% early-withdrawal penalty on top of income tax — the same rule as an IRA or 401(k). A governmental 457(b) has no such penalty. Once you leave the employer, you can withdraw at any age and only owe ordinary income tax, not the penalty.

For a nurse planning to leave the bedside for CRNA school, take a sabbatical, or retire before 60, a 457(b) can function as a bridge account — money you can tap penalty-free during the gap years. That's a use case the 403(b) simply can't match without workarounds like a Roth conversion ladder or rule-of-55 timing.

How to prioritize between them

For most nurses the order looks like this. First, contribute to whichever plan carries an employer match — usually the 403(b) — up to the full match, because that's free money. Next, if you value early-access flexibility and you have a governmental 457(b), it's a strong second priority, especially if early retirement or CRNA school is on your horizon. Then fill remaining space in the 403(b). A Roth IRA belongs somewhere in this stack too; see our Roth IRA vs 403(b) comparison for where it fits.
