If you work for a school, hospital, or nonprofit, you probably have a 403(b) instead of a 401(k). Here is how it works, what to watch out for, and how to avoid the costly mistakes most 403(b) participants make.
If you are a teacher, nurse, professor, doctor at a nonprofit hospital, government employee, or work for any tax-exempt organization, you probably do not have a 401(k). You have a 403(b). It works almost identically to a 401(k) in terms of contribution limits, tax benefits, and basic structure, and it sits in the same spot on the retirement account roadmap. But there are critical differences, particularly around investment options and fees, that can cost 403(b) participants tens of thousands of dollars over a career if they are not careful.
- The 403(b) and 401(k) have identical contribution limits ($24,500 in 2026), the same tax treatment (pre-tax traditional or after-tax Roth), and the same basic mechanics. The main difference is who offers them: 403(b) plans are for schools, hospitals, and nonprofits; 401(k) plans are for private-sector companies.
- The biggest 403(b) risk is high-fee annuity products. Many school-district plans are dominated by insurance-company annuities charging 1.5 to 3%+ in total annual fees, versus around 0.03% for a broad index fund. On $500/month over 30 years, a 1.5% fee can cost roughly $148,000 in lost growth versus a low-cost alternative. See the fee calculator below for your numbers.
- If your 403(b) offers any fund with “index” in the name and an expense ratio under 0.20%, that is usually the one to use. TIAA-CREF index funds (where available) often charge 0.05 to 0.10%, far less than the annuity products plan representatives tend to promote.
- The 403(b) has a catch-up provision available in no other plan: employees with 15+ years of service at the same employer who have contributed below historical maximums may add up to $3,000/year (up to $15,000 lifetime). Ask your plan administrator if it applies to you.
- Government employees with access to both a 403(b) and a 457(b) can contribute to each, $24,500 apiece, for $49,000/year, plus $7,500 in a Roth IRA. The governmental 457(b) has no early-withdrawal penalty after you leave the employer, which makes it useful for early retirement.
How does a 403(b) work?
Pre-tax contributions. You contribute a portion of your paycheck before taxes. A $500/month contribution reduces your taxable income by $500/month. In the 22% bracket, that saves about $110/month in taxes right away.
Tax-deferred growth. Investments grow without being taxed each year, no annual taxes on dividends, capital gains, or interest until withdrawal.
Taxed on withdrawal. When you withdraw in retirement (after age 59.5), you pay ordinary income tax on the withdrawals.
Roth option. Many 403(b) plans now offer a Roth option. Contributions are after-tax (no upfront deduction), but growth and withdrawals are tax-free. The same Traditional vs Roth decision applies as with a 401(k) or IRA.
Employer match. Some employers match contributions, common in hospitals and universities, less common in K-12 districts. If your employer matches, contributing at least enough to get the full match comes before other investment accounts.
What are the 403(b) contribution limits for 2026?
| Type | 2026 limit |
|---|---|
| Employee contribution (under 50) | $24,500/year |
| Catch-up (age 50+) | Additional $8,000/year ($32,500 total) |
| Super catch-up (ages 60 to 63) | Additional $11,250 ($35,750 total) |
| Special 403(b) catch-up (15+ years, same employer) | Additional $3,000/year (up to $15,000 lifetime) |
| Total limit (employee + employer) | $72,000/year |
The base and catch-up figures come from the IRS for 2026 (IR-2025-111); see our full 2026 contribution limits guide. The special 15-year catch-up is unique to 403(b) plans, with no 401(k) equivalent. These limits are separate from IRA contributions, so you can fund both your 403(b) ($24,500) and a Roth IRA ($7,500) in the same year for $32,000 in total tax-advantaged savings.

403(b) vs 401(k): what are the key differences?
| Feature | 403(b) | 401(k) |
|---|---|---|
| Who offers it | Schools, nonprofits, hospitals, churches | Private-sector companies |
| Contribution limit (2026) | $24,500 | $24,500 |
| Employer match | Sometimes (common in hospitals and universities) | Common (50 to 100% on first 3 to 6%) |
| Investment options | Often annuities + limited mutual funds | Usually mutual funds + index funds |
| Fees | Often high (annuity fees 1 to 3%+) | Varies (index options often 0.03 to 0.15%) |
| Vesting | Often immediate for employee contributions | Often 3 to 6 year vesting for employer match |
| 15-year catch-up | Yes ($3,000 extra/year, up to $15K lifetime) | No |
| ERISA protection | Sometimes exempt (church plans especially) | Always covered |
The fee problem: what do high expenses actually cost?
This is where many 403(b) participants get hurt. Many plans, particularly in K-12 districts, are dominated by annuity products from insurance companies such as TIAA, Equitable (formerly AXA), Valic, and Lincoln Financial. These products commonly charge:
- Mortality and expense (M&E) fees: 0.50 to 1.50% per year
- Administrative fees: 0.10 to 0.30% per year
- Underlying fund fees: 0.50 to 1.00% per year
- Surrender charges: 5 to 8% if you move money out within the first 5 to 10 years
Total annual fees can run 1.50 to 3.00%+. Compare that to a broad S&P 500 index fund at around 0.03%.

The $148,000 fee difference (concrete example)
A teacher contributing $500/month for 30 years at a 7% average return (illustrative):
| Low-cost index fund (0.03% fee) | ~$567,000 |
| Typical annuity product (1.50% fee) | ~$419,000 |
| Fee difference | ~$148,000 lost to fees |
That gap is several years of retirement income. Use the fee impact calculator above to see your specific numbers.
How do you get the best investments in your 403(b)?
Step 1: Find the low-cost option in your plan
Some 403(b) plans include Fidelity or Vanguard index fund options alongside the annuity products. Look for any fund with “index” in the name and an expense ratio under 0.20%, TIAA-CREF index funds (some plans offer them at 0.05 to 0.10%), or Vanguard and Fidelity funds if your plan lists them. Log into your plan portal and check the expense ratios on every available fund. If you see an option under 0.20%, that is usually the one to use.
Be cautious if a plan representative steers you toward annuity products. Annuity salespeople often earn commissions on what they recommend, so their incentive can favor the higher-fee product rather than the one that serves your retirement best.
Step 2: If the plan has no low-cost options, use the Roth IRA first
If your 403(b) options are all high-fee annuities, a common approach is:
- Contribute to the 403(b) up to the employer match (if any), since free money justifies even a high-fee plan.
- Max your Roth IRA ($7,500/year) at Fidelity, Schwab, or Vanguard with index funds at 0.03 to 0.08%.
- If you can save more after maxing the Roth IRA, increase 403(b) contributions. Even in a high-fee plan, the tax deduction still has some value.
Step 3: Advocate for better options
Ask your HR department or school board to add a low-cost vendor to the approved list. The nonprofit 403bwise.org offers advocacy tools and sample letters. Some states now require at least one low-cost index fund option in district plans, and when employees coordinate, many districts have added Fidelity or Schwab after the request.
TIAA: the most common 403(b) provider
TIAA (Teachers Insurance and Annuity Association) is the largest 403(b) provider, serving most universities and many districts. TIAA products vary widely in quality:
TIAA Traditional Annuity: a guaranteed-interest account that has recently paid roughly 3 to 4% (sometimes higher). It is unique to TIAA with no 401(k) equivalent, and the guaranteed rate can make it a reasonable bond substitute for conservative investors. It does have liquidity restrictions: withdrawing the full balance can require a Transfer Payout Annuity process spread over 84 months (7 years). Check the terms before relying on it for a rollover strategy.
TIAA-CREF Lifecycle Funds: target-date funds around 0.25 to 0.40% expense ratios. Workable, though more expensive than Vanguard (about 0.08%) or Fidelity (about 0.12%) target-date funds. If they are your only target-date option, they are usable.
TIAA-CREF Index Funds: some plans offer pure index funds at 0.05 to 0.10%. If available in your plan, these are typically the strongest option within TIAA.
TIAA Real Estate Account: a fund investing directly in physical real estate (not publicly traded REITs). It offers direct real estate exposure most plans do not, and can be a diversification tool if your plan includes it.
The 457(b): the government employee advantage
State and local government employees often have access to both a 403(b) and a 457(b). The 457(b) is a separate tax-advantaged account with its own $24,500 contribution limit in 2026, independent of the 403(b) limit.
Having access to both means a government employee can potentially contribute:
- $24,500 to the 403(b)
- $24,500 to the 457(b)
- $7,500 to a Roth IRA
- Total: $56,500/year in tax-advantaged savings
The key 457(b) advantage: no early-withdrawal penalty. With a governmental 457(b), you can withdraw at any time after separating from the employer, regardless of age. That makes it a useful early retirement vehicle, often more flexible than the 403(b) for anyone planning to retire before 59.5.
A common priority for government employees with both: contribute to each plan up to the employer match, then max the 457(b) before the 403(b) for its flexibility, then max the 403(b), then max the Roth IRA.
What happens when you leave your employer?
When you leave a job with a 403(b), the same options apply as with a 401(k): roll to a Traditional IRA (often the most flexible, with the widest investment choice and lowest fees), roll to a new employer’s 403(b) or 401(k), leave it in the old plan temporarily, or cash out (the option to avoid, since it triggers income tax plus a 10% penalty on the full balance).
Important TIAA Traditional Annuity note: this specific product has liquidity restrictions that complicate rollovers. TIAA may require a Transfer Payout Annuity spread over 84 months, or a lump-sum transfer with penalties. Check your account terms and plan documents before any rollover involving TIAA Traditional.
Frequently Asked Questions
Yes. Contributing to a 403(b) does not affect your Roth IRA eligibility; only your income does (the Roth phase-out begins at $153,000 single / $242,000 married filing jointly in 2026). Having both is the standard setup: use the 403(b) for the match and tax deduction, then max the Roth IRA at a low-cost brokerage. The limits are separate ($24,500 and $7,500), so you can fund both in the same year.
The same framework as Traditional vs Roth IRA applies. In the 10 to 12% bracket, the Roth 403(b) is often better: pay tax now at a low rate, withdraw tax-free later. In the 22% bracket, the Roth is still frequently attractive for long-term savers expecting income growth. In the 32%+ bracket, the Traditional deduction delivers meaningful current-year savings. Not all plans offer the Roth option, so check with your administrator.
Log into your plan’s online portal (ask HR for the link) and look for the fund lineup with expense ratios. If fees are not shown, request the fee disclosure document. The nonprofit 403bwise.org also rates many district plans by fees and investment quality. If every fund charges above 0.50%, you are in a high-fee plan and the Roth IRA is usually the better priority account.
It is a catch-up unique to 403(b) plans. Employees with at least 15 years of service at the same eligible employer who have averaged under $5,000 in contributions per year historically may add up to $3,000/year, capped at $15,000 lifetime. It stacks on top of the standard age-50+ catch-up, so some long-tenured employees can contribute up to $35,500/year ($24,500 + $8,000 + $3,000). The calculation is complex, so ask your administrator to run it for your service history.
Both are tax-advantaged plans with the same $24,500 limit in 2026, but the 403(b) is for schools, nonprofits, and hospitals, while the 457(b) is for state and local government (and some nonprofit) employees. The key distinction: a governmental 457(b) has no 10% early-withdrawal penalty after you separate from the employer, regardless of age, while the 403(b) follows the standard 59.5 rule. Employees with access to both can contribute to each, for a combined $49,000/year.
Most 403(b) plans allow loans up to 50% of the vested balance or $50,000, whichever is less, the same as 401(k) loans, repaid within 5 years (longer for a primary residence). If you leave before repaying, the balance may become due or be treated as a taxable distribution plus a 10% penalty. The borrowed amount stops growing while the loan is outstanding, so treat 403(b) loans as a last resort.
Yes. When you leave your employer, you can roll the balance into a Traditional IRA, which usually gives you the most control, the widest investment choice, and the lowest fees. Use a direct rollover (the check payable to the new custodian, not to you) to keep it tax-free. The TIAA Traditional Annuity is the exception, since it may require a payout spread over 84 months.
Partly. If there is a match, contribute enough to capture it, since a 50 to 100% immediate return outweighs high fees. Beyond the match, weigh the fee level: under 1%, continued contributions make sense for the deduction; at 1.5 to 2%+, max the Roth IRA first; at 2.5%+ (the worst annuities), a taxable brokerage with index funds may preserve more wealth beyond the match. The fee impact calculator above shows the breakeven for your situation.
The bottom line
The 403(b) is a powerful retirement tool for teachers, nurses, professors, and nonprofit workers, but it needs more vigilance than a typical 401(k) because high-fee annuity products are so common. Many participants quietly lose $100,000 to $200,000 over a career simply by accepting whatever a plan representative recommends without checking the expense ratios.
The checklist: contribute at least enough to get the employer match, check your plan for index fund options under 0.20%, understand the total fees and surrender charges before choosing any annuity, max your Roth IRA at a low-cost brokerage alongside your 403(b), and use the fee impact calculator above to quantify what you are paying.
