403(b) and 457(b) Guide for Families: 2026 Limits, the Double-Up Strategy, and the Annuity Trap

One spouse works for a school district, hospital system, university, or nonprofit — and has a 403(b) instead of a 401(k). Same dollar limits, different rules. Government employees and public school teachers who have both a 403(b) and a 457(b) can contribute the full limit to each plan independently — effectively doubling their tax-deferred savings. This guide explains what changes for your household and includes a calculator for your total contribution capacity.

What is a 403(b) plan?

A 403(b) is a tax-sheltered annuity (TSA) plan authorized under IRC § 403(b). Eligibility is limited to employees of:

• Public schools and school districts — teachers, administrators, support staff
• 501(c)(3) tax-exempt organizations — nonprofits, charities, foundations
• Hospitals and health systems — nurses, physicians, allied health staff at nonprofit hospital systems
• Universities and colleges — faculty, staff, researchers
• Churches and religious organizations

For most purposes a 403(b) works like a 401(k): pre-tax (or Roth) contributions reduce taxable income, investments grow tax-deferred, and withdrawals in retirement are taxed as ordinary income. The same annual dollar limits apply. The meaningful differences are in investment options, an exclusive catch-up provision, and — if your employer also offers a 457(b) — a second fully independent contribution limit.

The 15-year catch-up: 403(b)'s unique feature

Employees who have worked for the same 403(b)-eligible employer for at least 15 years may qualify for an additional $3,000 per year under IRC §402(g)(7) — regardless of age, so this applies even if you're in your 30s or 40s.

Qualification rules:

• Minimum 15 consecutive years at the same qualifying employer
• Average past contributions to this employer's plan must be under $5,000/year over your tenure
• Lifetime maximum: $15,000 in 15-year catch-up contributions across all employers
• IRS ordering rules apply: the 15-year catch-up is applied before the age-50+ catch-up, reducing the available 50+ space dollar-for-dollar up to $10,000/year combined¹

Who this helps most: A teacher or hospital nurse who started contributing modestly, has 15+ years at the same district or hospital system, and has a total balance lower than tenure would suggest. A 42-year-old teacher meeting the criteria could contribute $27,500 in 2026 — six years before anyone in a 401(k) gets their first catch-up.

The 403(b) annuity trap

403(b) plans are called "tax-sheltered annuities" because historically they were funded almost entirely by insurance company annuity products. Many plans — especially older school district and hospital plans — still default to or require annuities. The problem:

• High expense ratios: Variable annuities inside 403(b) plans can carry total costs of 1.5%–3%+ per year, including mortality and expense (M&E) charges on top of fund expenses. At 2% drag vs. a 0.05% index fund plan, a teacher loses roughly $300K–$600K in wealth over a 30-year career.
• Surrender charges: Some annuity contracts lock contributions for 7–10 years with declining surrender penalties (7%+ in year 1, stepping down to zero).
• Limited investment menus: Many older 403(b) plans offer only the insurance company's proprietary products.

What to do:

1. Find your plan's investment options and total expense ratios (search the fund name + "expense ratio" or look in the fund's prospectus)
2. If stuck in high-fee products, contribute only enough to capture the full employer match — then redirect extra savings to the 457(b) (if available), a Roth IRA, or the other spouse's lower-cost 401(k)
3. Ask HR if a vendor change or self-directed brokerage option is available — many large school districts now offer Vanguard or Fidelity options
4. TIAA Traditional (common at universities) is different: it's a stable-value contract backed by TIAA's general account with a guaranteed minimum crediting rate, not a high-fee variable annuity

457(b) deferred compensation plans

A 457(b) is a deferred compensation plan available to employees of state and local governments and most nonprofits. Two types:

• Governmental 457(b): Offered by public school districts, state agencies, municipalities, and public universities. Assets are held in a trust separate from the employer — no creditor risk if the employer has financial problems. This is the version most families want.
• Nonprofit 457(b): Offered by 501(c)(3) organizations. Assets remain an unsecured obligation of the employer. Contribution limits are the same, but there is counterparty risk.

The 457(b) no-penalty rule is a major early-retirement planning tool. A teacher who retires at 56 can draw from their 457(b) the day they leave — with no 10% penalty, no 72(t) SEPP complexity. If your household is targeting early retirement, the 457(b) is typically the first account to draw from.

The double-up strategy: 403(b) + 457(b)

If your employer offers both a 403(b) and a governmental 457(b) — as many public school districts and state employers do — you can contribute the full limit to each plan independently. The 403(b) and 457(b) limits are not aggregated under IRS rules.²

Add a maxed Roth IRA ($7,500–$8,600 depending on age) and a family HSA ($8,750 + $1,000 catch-up at 55+) and a public school teacher at ages 60–63 can shelter over $80,000 per year — while their corporate-401(k) counterpart at the same income caps out around $45,000.

Priority framework for the double-up:

1. Capture the full 403(b) employer match first (free money, no alternative)
2. If the 403(b) investment menu has high-fee annuities, fund the 457(b) next — it typically offers better investment options
3. Return to fill the 403(b) if you want more tax-deferred room and the plan has low-cost options
4. Roth IRA ($7,500/person) for tax diversification
5. HSA if on an HDHP — triple tax advantage

When one spouse has a 403(b) and the other has a 401(k)

The most common family scenario: one spouse works corporate (401(k)), one works for a school district or hospital (403(b)). The dollar limits are identical — $24,500/person in 2026 — so the household contribution math looks the same as two-401(k) families. What changes:

• Investment quality may differ significantly. If the 403(b) plan has high-fee annuity products, prioritize filling the 401(k) after capturing the 403(b) employer match. A 2% fee drag vs. a 0.05% index fund costs the 403(b) spouse hundreds of thousands over a 30-year career.
• Early retirement sequencing differs. If the 403(b) spouse also has a 457(b), that account has no early withdrawal penalty — draw it first before age 59½.
• Roth 403(b) is available if the plan supports it. Same as Roth 401(k): no income limit. Make the Roth vs. traditional decision at the household level based on your current marginal rate vs. expected retirement rate.
• RMDs apply the same way. Required Minimum Distributions begin at age 73 (born 1951–1959) or 75 (born 1960+) per SECURE 2.0 §107. Roth 403(b) accounts are no longer subject to lifetime RMDs starting 2024 (SECURE 2.0 §325) — another reason to use the Roth option if offered.
• Rollover is straightforward. When the 403(b) spouse changes employers, the 403(b) can roll directly to an IRA, 401(k), or a new employer's 403(b) — same mechanics as a 401(k) rollover.

Key takeaways for 403(b) and 457(b) families

1. The limits are the same as a 401(k). $24,500 base in 2026 — don't assume the 403(b) is inferior by design.
2. Check fees before maxing. If the 403(b) plan is annuity-heavy, contribute only to the match, then put the rest elsewhere.
3. If you have a 457(b) at the same employer, use it. It is an entirely separate contribution limit — effectively a second 401(k) with no early withdrawal penalty.
4. The 15-year catch-up is real but needs plan administrator confirmation. If you've been at the same employer 15+ years with modest historical contributions, ask HR explicitly.
5. The 457(b) no-penalty rule changes early retirement math. For households targeting retirement before 59½, the 457(b) should be funded and drawn first.
