403(b) Plans for Hospital Physicians: 2026 Complete Guide

If you're employed by a hospital, health system, or nonprofit medical practice, you almost certainly have a 403(b) — not a 401(k). The two are functionally similar, but they differ in one genuinely useful way for long-tenured physicians and in one costly way (the investment menu). Most employed physicians underuse their 403(b) because they assume it's identical to what a corporate employee has. It's not.

What Is a 403(b)?

A 403(b) — formally a "tax-sheltered annuity plan" under IRC § 403(b) — is a defined-contribution retirement plan available to employees of tax-exempt organizations (§ 501(c)(3)), public schools, and government entities. Every large hospital system and most academic medical centers qualify.

Mechanics are nearly identical to a 401(k): you elect to defer a percentage of your W-2 salary before taxes, the money is invested in plan options, and you pay taxes when you withdraw in retirement. Two differences matter for physicians:

• 15-year service catch-up: A 403(b)-only provision that can allow an extra $3,000/year in contributions if you've worked for the same employer 15+ years and your historical contribution rate was low. More on this below — and why it rarely applies to physicians who have been maxing out.
• Investment menu: Historically dominated by variable annuity contracts from insurance carriers. Many plans now include mutual fund options, but you may still need to hunt for low-cost index funds. A 401(k) at a tech company rarely has this problem; a 403(b) at a nonprofit hospital often does.

2026 Contribution Limits

The IRS announced 2026 403(b) limits in IR-2025-244.¹

The annual additions limit ($72,000) caps the total of your contributions plus any employer match and non-elective contributions. For hospital physicians, the employer match is typically 3–6% of salary. At $350,000 base, a 4% match = $14,000 employer contribution. Combined with $24,500 employee deferral, total additions = $38,500 — well under $72,000. Few hospital-employed physicians hit the §415 ceiling through their 403(b) alone.

The 15-Year Service Catch-Up — Why It Rarely Helps Physicians

The 403(b) includes a provision unavailable in any other plan type: if you have 15 or more years of service with the same qualifying employer, you may be able to contribute an extra $3,000/year, up to a lifetime maximum of $15,000.²

Here's the catch. The additional room is calculated as the least of:

1. $3,000
2. $15,000 minus prior years' contributions made under this rule
3. $5,000 × years of service minus total contributions made to any 403(b) with this employer in all prior years

The third prong is the binding constraint for most physicians. A doctor who has worked at one hospital for 15 years and contributed $24,000/year has made $360,000 in cumulative contributions. The available room under prong 3: ($5,000 × 15) − $360,000 = $75,000 − $360,000 = negative. No additional room.

The 15-year catch-up realistically benefits employees who contributed minimally early in their careers — think an academic physician who spent years at the $5,000–$10,000/year deferral rate before raising their income. If you've been maxing your 403(b) since your first year as an attending, the calculation will likely show no additional room available.

Worth checking anyway: your HR or plan administrator can calculate your available 15-year catch-up room if you've been at the same institution for 15+ years. If there's room, it's a free $3,000 that would otherwise be unavailable.

Roth vs. Traditional 403(b)

Many hospital plans now offer a Roth 403(b) option. Unlike a Roth IRA, the Roth 403(b) has no income limit — you can contribute regardless of how much you earn. The same $24,500 deferral limit applies; you choose whether contributions go in pre-tax (traditional) or after-tax (Roth).

The framing is simple: traditional saves taxes now, Roth saves taxes later. The math depends on your current rate versus your expected retirement rate.

One structural advantage of the Roth 403(b): SECURE 2.0 (§ 325) eliminated required minimum distributions from Roth 401(k)/403(b) accounts starting January 1, 2024.³ Previously, Roth 403(b) accounts were subject to RMDs while Roth IRAs were not — a quirk that caused many physicians to roll their Roth 403(b) to a Roth IRA on separation. That rollover is still a reasonable strategy (for better investment options), but the RMD reason no longer applies.

Stacking With 457(b) and Backdoor Roth

This is the biggest financial advantage hospital-employed physicians have over their private-practice peers. The 457(b) elective deferral limit is completely separate from the 403(b) limit. Max both and you can defer twice as much.

At a 37% federal bracket plus 5–9% state income tax, sheltering $65,000–$81,000 from taxes saves $27,000–$38,000+ in the current year. Over a 20-year attending career, the compounding effect of that annual tax deferral is substantial — often $1M+ in incremental retirement wealth compared to saving the same dollars in a taxable account.

A few caveats on the 457(b) side: most hospital non-governmental 457(b) plans carry employer-creditor risk. Read the 457(b) guide before maxing that account; the 403(b) should always be funded first.

The Investment Menu Problem

This is where hospital 403(b) plans frequently hurt physicians — especially those who enrolled during residency without scrutinizing the fund options.

Historically, 403(b) plans were structured around annuity contracts from insurance carriers (TIAA-CREF, Voya, Lincoln, MetLife, etc.). Insurance companies marketed directly to hospitals and dominated the space. Many plans still include variable annuity products as default or only options. These contracts often carry:

• Annual expense ratios of 0.5–1.5% for the annuity wrapper, on top of underlying fund expenses
• Surrender charges if you exit before a set period
• Mortality and expense fees that compound against you silently

The difference between a 0.05% index fund and a 1.2% variable annuity product over 30 years on $500,000 in assets is roughly $600,000 in forgone wealth. This is not a rounding error.

What to look for in your plan:

1. Request the full fund lineup from HR or the plan website. Many plans include both annuity and mutual fund options — you may have access to Vanguard or Fidelity index funds you don't know about.
2. Look for a self-directed brokerage window (SDBO). Some plans offer a brokerage account as a sub-option, giving access to thousands of mutual funds and ETFs. Usually costs $50–$100/year but opens the full fund universe.
3. Compare expense ratios. A total market index fund should cost under 0.05%. Any fund above 0.5% deserves scrutiny.
4. Identify what you're actually in. If you enrolled during orientation and never changed your allocation, check whether you're defaulted into an annuity product or a target-date fund — and at what cost.

Rollover Strategy When You Leave

When you leave a hospital — to join a different health system, open a private practice, or retire — your 403(b) balance can be rolled over without triggering taxes.⁴

Options on separation:

• Leave it in the plan: Allowed if balance exceeds $7,000 (2026 SECURE 2.0 threshold). Often the default, but not always the best choice if the investment menu is limited.
• Roll to an IRA: Most common choice. Moves the money to a rollover IRA where you have full investment flexibility. Use a direct rollover (trustee-to-trustee) to avoid mandatory 20% withholding.
• Roll to a new employer's plan: If your new hospital has a better 403(b) or 401(k), rolling into it preserves plan loan options and may simplify bookkeeping.

One important caveat if you use the backdoor Roth: Rolling pre-tax 403(b) funds into a traditional IRA creates a problem. The pro-rata rule will apply to any future backdoor Roth conversions, potentially triggering unexpected taxes. If you're an active backdoor Roth user, consider rolling the pre-tax 403(b) into your new employer's 401(k) or 403(b) — not to an IRA — so the pro-rata calculation doesn't apply to your IRA balance.

Roth 403(b) balances can be rolled to a Roth IRA cleanly, with no tax consequences and no pro-rata complications.

Decision Framework for Hospital-Employed Physicians

Here's the order of operations for 403(b) decisions:

Step 1 — Capture the full employer match

If your employer matches 4% of salary and you're only deferring 3%, you're leaving free money behind. Adjust your contribution election to at least the match threshold first.

Step 2 — Choose traditional or Roth

Residents and fellows: Roth, almost always. Attendings in the 32%+ bracket with no pension: traditional usually wins. If you have pension income, Social Security, and significant pre-tax balances already, Roth or split deserves serious consideration. This is worth modeling with a fee-only advisor if you're unsure.

Step 3 — Fund the backdoor Roth first if you're not yet maxing 403(b)

The backdoor Roth ($7,500/person in 2026) gets you tax-free growth and no RMDs. If forced to choose between the last $7,500 of 403(b) contribution and a backdoor Roth, the Roth usually wins on long-run tax efficiency.

Step 4 — Max the 403(b) to $24,500

At attending-level income, this should be non-negotiable. The tax savings in a 35–37% bracket on $24,500 of deferred income is $8,575–$9,065 in avoided federal taxes alone.

Step 5 — Add 457(b) deferrals if available and plan is stable

After maxing 403(b) and backdoor Roth, the 457(b) is the next lever. Check whether your plan is governmental or non-governmental before loading it heavily. See the 457(b) guide for the full analysis.

Step 6 — Audit your investment options

Once you've set the right deferral amount, confirm you're in the lowest-cost funds available. Even a 1% annual improvement in net return (through lower expense ratios) adds up to $200,000+ on a $500,000 balance over 20 years.
