The Hospital 403(b): A Nurse's Complete Guide

If you work at a hospital or health system, your main retirement savings vehicle is a 403(b) — the nonprofit sector's equivalent of a 401(k). Most nurses get a brief enrollment pitch from HR and then never think about it again. This guide covers everything you actually need to know: how much you can contribute, whether to use traditional or Roth, what to do about TIAA, how to stack a 457(b) on top, and what happens to the money when you leave.

403(b) vs. 401(k): What's actually different

A 403(b) is the retirement savings plan offered by nonprofits (including 501(c)(3) hospital systems), public schools, and some government employers. The rules are nearly identical to the 401(k) your friends in the private sector use, with a few nursing-relevant differences:

• Same IRS contribution limits — for 2026, $24,500 in elective deferrals, with catch-up provisions identical to 401(k).¹
• Eligible for 457(b) stacking — nonprofit hospital employees often have access to a separate 457(b) deferred compensation plan with its own independent contribution limit. This is a major advantage over private-sector 401(k) plans, which can't be stacked this way.
• TIAA and annuity-heavy fund menus — many hospital 403(b) plans offer TIAA annuity products prominently or even as the default. These are often expensive and complex compared to low-cost index funds.
• 15-year catch-up rule (mostly obsolete) — 403(b) plans have a legacy "15-year rule" allowing an extra catch-up if you've been with the same employer 15+ years. In practice, the standard age-50 catch-up is larger, and most nurses never use this provision.
• PSLF interaction — 403(b) contributions are pre-tax, reducing your Adjusted Gross Income. For nurses on IDR plans pursuing PSLF, lower AGI means lower monthly payments, which reduces the cost of pursuing forgiveness.

2026 403(b) contribution limits

The IRS sets these annually. For 2026:¹

• Standard deferral limit: $24,500
• Catch-up (age 50–59 and 64+): additional $8,000 — total $32,500
• Super catch-up (ages 60–63, SECURE 2.0): additional $11,250 — total $35,750
• Total employer + employee additions limit (IRC §415c): $72,000

These are elective deferral limits — how much of your own paycheck you can put in. Employer contributions (matching or non-elective) come on top of the $24,500, subject to the $72,000 overall limit.

The 403(b) + 457(b) dual-bucket: the most under-used move in hospital nursing

This is the single biggest retirement savings advantage nurses at nonprofit hospitals have over their private-sector peers, and most nurses have never been told about it.

If your employer (hospital or health system) offers both a 403(b) and a 457(b) deferred compensation plan, the IRS treats their contribution limits as completely separate. In 2026:

• Max your 403(b): $24,500
• Max your 457(b): $24,500
• Combined tax-deferred savings: $49,000 per year — before any employer match

This is why we reference the "$49K combined" figure throughout the site. For a staff RN earning $92,000, contributing $49,000 annually to these two accounts would shelter 53% of gross income from current federal tax. Very few employees in the US have this option.

How to find your 457(b)

The 457(b) is typically called "deferred compensation" in your benefits portal and is often in a separate menu from the 403(b). Common names: "457 Plan," "Executive Deferred Compensation," or just "Deferred Compensation Program." HR often fails to mention it at onboarding because it was originally designed for hospital executives, though rank-and-file employees are usually eligible too.

Governmental vs. non-governmental 457(b) — an important distinction

Government employers (VA, county health departments, public university hospitals) offer governmental 457(b) plans. Nonprofit hospital systems (most private hospital 403(b) employers) offer non-governmental 457(b) plans.

The key difference: non-governmental 457(b) assets are technically a general asset of the employer until distributed — they're not held in a trust the way 401(k) and 403(b) money is. If the hospital system went bankrupt, your 457(b) balance could theoretically be at risk as a creditor claim. In practice this risk is small for large health systems, but it's worth factoring in before loading the 457(b) heavily at a financially stressed hospital.

Governmental 457(b) funds (at VA, public hospitals) are held in trust and not subject to this risk.

Traditional vs. Roth 403(b)

Many hospital plans now offer a Roth option within the 403(b). The contribution limits are the same ($24,500) — but you choose whether contributions go in pre-tax (traditional) or after-tax (Roth).

When traditional 403(b) is better

• You're currently in the 22%, 24%, or higher federal bracket and expect to be in a lower bracket in retirement
• You're pursuing PSLF and want to lower AGI to reduce monthly IDR payments
• You have high 1099 income and want to reduce self-employment tax exposure (pre-tax deferral doesn't help with SE tax, but it does help with income-based calculations like IRMAA)

When Roth 403(b) is better

• You're a new grad nurse in the 12% or lower bracket — Roth contributions are cheap tax-wise now, and the balance grows tax-free for decades
• You expect income to rise significantly (e.g., RN now, planning CRNA school)
• You're a CRNA or NP who has maxed pre-tax accounts and wants tax diversification in retirement
• You want to avoid required minimum distributions (Roth 403(b) still has RMDs during your lifetime — unlike Roth IRA — but this difference will largely disappear in practice if you roll to a Roth IRA at retirement)

The TIAA annuity problem

TIAA (formerly TIAA-CREF) is the dominant provider in nonprofit hospital 403(b) plans. This is not always a problem — TIAA's index funds are competitively priced. The problem is TIAA's annuity products and the way they're marketed.

What often happens

At many hospitals, HR routes new employees to TIAA enrollment. The TIAA representative may present products like TIAA Traditional (a fixed annuity) or variable annuities as the default. These products have features — liquidity restrictions, surrender charges, complex payout rules — that are poorly suited to nurses who may change employers or need flexibility.

What to look for instead

Most hospital 403(b) plans that use TIAA also offer TIAA's mutual fund lineup, which includes low-cost Vanguard-equivalent index funds (TIAA-CREF Equity Index, Social Choice, and similar). These often have expense ratios below 0.10%.

If your plan also includes Fidelity, Vanguard, or Schwab options alongside TIAA, look at those fund menus too. Target-date index funds (e.g., Vanguard Target Retirement 2050 at 0.08% expense ratio) are a reasonable one-decision option for nurses who don't want to manage allocations.

Red flags in your 403(b) fund menu

• Expense ratios above 0.50% — you can almost certainly find equivalent funds cheaper
• Surrender charges or "liquidity restrictions" on your balance — a sign of annuity products
• Only actively managed funds listed — index funds should be available in any hospital plan
• A "default" investment that isn't a target-date fund or money market — check what you're actually invested in after enrollment

Vesting: what the hospital's contributions require

Your own deferral contributions (the money you put in) are always immediately 100% yours. You're never at risk of losing what you contributed.

Employer contributions (matching or non-elective) often have a vesting schedule — you must stay employed for a set number of years before those contributions fully belong to you. Common structures:

• Immediate vesting: Employer contributions are yours from day one. Ideal for travel nurses or those who change employers frequently.
• Cliff vesting: 0% until a set date (often 2–3 years), then 100%. Leaving before the cliff means forfeiting all employer contributions.
• Graded vesting: Phased over 2–6 years (e.g., 20% per year). Partial credit for shorter tenures.

For travel nurses on 13-week contracts, vesting almost never applies — the employer match is usually irrelevant because you won't be there long enough to vest. Focus on your own contributions to a personal IRA or Solo 401(k) instead.

What happens to your 403(b) when you leave the hospital

This is where nurses often make expensive mistakes. Your options when leaving a job:

Option 1: Roll over to a Traditional IRA (usually best)

A direct rollover to an IRA at Fidelity, Vanguard, or Schwab gives you full control over fund selection, no expense constraints, and continues tax-deferred growth. Request a "direct rollover" — the check goes to the new custodian, not to you, which avoids mandatory 20% withholding and avoids triggering a taxable event.

Option 2: Roll over to new employer's 403(b) or 401(k)

If the new plan has good, low-cost fund options, rolling into the new plan keeps things consolidated and preserves the ability to take a 403(b) loan if your new plan allows it. Also useful if you're pursuing PSLF — keeping assets in a qualified plan doesn't affect PSLF eligibility.

Option 3: Cash out (almost never a good idea)

Cashing out triggers ordinary income tax plus a 10% early withdrawal penalty (if under 59½) on the entire balance. A $30,000 403(b) balance becomes roughly $19,000–$21,000 after taxes and penalties for a nurse in the 22% bracket. This is one of the most costly financial mistakes nurses make when leaving a hospital.

Option 4: Leave it in the old plan

You can usually leave a balance in a former employer's 403(b) if it's above the plan's minimum (often $5,000). This makes sense if the old plan has excellent funds or if you're within a year of retirement. Otherwise, rolling to an IRA gives you more control.

How the 403(b) interacts with PSLF

This connection matters more than most nurses realize. Here's the mechanism:

• Traditional 403(b) contributions reduce your Adjusted Gross Income (AGI)
• IDR (income-driven repayment) monthly payments are calculated as a percentage of discretionary income, which is based on AGI
• Lower AGI = lower IDR monthly payment = more loan balance eligible for tax-free PSLF forgiveness at month 120

Example: An RN with $80,000 AGI and $95,000 in federal loans. On SAVE (or IBR), the monthly payment is approximately $550. If she contributes $24,500 to her 403(b), AGI drops to ~$55,500 and monthly payment falls to roughly $350. Over 10 years, that's a $24,000 difference in out-of-pocket payments — plus a larger remaining balance forgiven at month 120 (tax-free for PSLF).

This is why, for nurses with significant federal student loan debt at nonprofit hospitals, maxing the traditional 403(b) isn't just about retirement savings — it's also part of the PSLF optimization strategy.

403(b) strategy by role

Bedside RN / Staff nurse

Priority order: (1) Employer match in 403(b) to capture free money. (2) Check if your hospital offers a 457(b) — enroll and contribute as much as cash flow allows. (3) If pursuing PSLF, use traditional 403(b) to reduce AGI. (4) If not pursuing PSLF, consider Roth 403(b) if you're in the 12–22% bracket. See the full Staff RN Financial Planning guide.

Hospital W-2 NP

At $115K–$135K, you're in the 22–24% bracket. Traditional 403(b) deferral makes strong sense. Max the 403(b) first, then the 457(b) if available, then Roth IRA (backdoor if over income limit). See the NP Financial Planning guide for the full picture.

Hospital W-2 CRNA

At $200K–$280K, you're in the 32–35% bracket. Pre-tax 403(b) deferral is very valuable — each dollar deferred saves 32–35 cents in federal taxes now. Stack the 457(b) on top. The 403(b) alone caps at $24,500; with a 457(b), you can defer $49,000 pre-tax. See the CRNA Financial Planning guide for the W-2 vs. 1099 comparison — the 403(b)/457(b) stack is one of the advantages that can tip the W-2 math in certain markets.

1099 CRNA or independent NP (no 403(b) access)

If you're a 1099 contractor, you don't have access to a hospital 403(b). Your equivalent (and potentially more powerful) option is a Solo 401(k), which allows up to $72,000 in total contributions in 2026 ($24,500 employee deferral + up to 25% of W-2 comp as employer contribution). See the 1099 CRNA Calculator and the Locum CRNA Financial Planning guide.

The most common 403(b) mistakes nurses make

1. Contributing only enough to get the match, then stopping. The match is the floor, not the ceiling. Once it's captured, keep contributing — the tax deferral compounds over decades.
2. Defaulting into a TIAA annuity without knowing it. Check what you're actually invested in. Many nurses auto-enroll and have never looked at their fund allocations.
3. Not knowing the 457(b) exists. This is the single most common missed opportunity at non-profit hospital systems.
4. Cashing out when changing hospitals. This triggers taxes + penalties and destroys decades of compounding. Always roll over.
5. Using pre-tax 403(b) when Roth would be better. New grads in low brackets should often be using Roth — the future tax savings are more valuable than the current deduction.
6. Ignoring the PSLF interaction. For nurses on IDR pursuing PSLF, maximizing pre-tax 403(b) contributions is part of loan management, not just retirement planning.
