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. 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 ($23,500 in 2026), the same tax treatment (pre-tax traditional or after-tax Roth), and the same basic mechanics. The primary 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 — compared to 0.03% for a Vanguard index fund in a 401(k). On $500/month contributions over 30 years, a 1.5% fee costs roughly $148,000 in lost growth vs a low-cost alternative. See the fee calculator below for your specific numbers.
- If your 403(b) offers any fund with “index” in the name and an expense ratio under 0.20%, use it. TIAA-CREF index funds (if available in your plan) typically charge 0.05 to 0.10% and are far superior to the annuity products that plan representatives often promote.
- The 403(b) has a unique catch-up provision available to no other plan: employees with 15+ years of service at the same employer who have contributed below historical maximums can contribute an additional $3,000/year (up to $15,000 lifetime). Check with your plan administrator if this applies to you.
- Government employees who have access to both a 403(b) AND a 457(b) can contribute to both simultaneously — $23,500 each, for $47,000/year total, plus $7,000 in a Roth IRA = $54,000/year in tax-advantaged retirement savings. The 457(b) has no early withdrawal penalty after leaving your employer, making it an ideal early retirement account.
How a 403(b) works
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, you save $110/month in taxes immediately.
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 completely 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 school districts. If your employer matches, contribute at least enough to get the full match before considering any other investment account.
403(b) contribution limits for 2026
| Type | Limit |
|---|---|
| Employee contribution (under 50) | $23,500/year |
| Catch-up (age 50+) | Additional $7,500/year ($31,000 total) |
| Special 403(b) catch-up (15+ years at same employer) | Additional $3,000/year (up to $15,000 lifetime) |
| Total limit (employee + employer) | $70,000/year |
The special 15-year catch-up is unique to 403(b) plans with no 401(k) equivalent. These limits are also entirely separate from IRA contributions — you can max both your 403(b) ($23,500) and a Roth IRA ($7,000) in the same year for $30,500 in total tax-advantaged savings.

403(b) vs 401(k): key differences
| Feature | 403(b) | 401(k) |
|---|---|---|
| Who offers it | Schools, nonprofits, hospitals, churches | Private-sector companies |
| Contribution limit (2026) | $23,500 | $23,500 |
| 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 high expenses actually cost you
This is where many 403(b) participants get hurt. Many plans — particularly in K-12 school districts — are dominated by annuity products from insurance companies like TIAA, Equitable (formerly AXA), Valic, and Lincoln Financial. These products 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% penalty if you move money out within the first 5 to 10 years
Total annual fees: 1.50 to 3.00%+. Compare this to a Vanguard S&P 500 index fund at 0.03%.

The $148,000 fee difference (concrete example)
A teacher contributing $500/month for 30 years at 7% returns:
| 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 $148,000 represents 3 to 4 years of retirement income. Use the fee impact calculator above to see your specific numbers.
How to 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 expense ratio under 0.20%, TIAA-CREF index funds (some plans offer at 0.05 to 0.10%), or Vanguard/Fidelity funds if your plan lists them. Log into your plan portal and look at the expense ratios on every available fund. If you see any option under 0.20%, use it.
Do not let a plan representative steer you toward annuity products. Annuity salespeople often earn commissions on the products they recommend. Their incentive is to sell you the higher-fee product, not 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:
- Contribute to the 403(b) only up to the employer match (if any) — free money justifies even a high-fee plan
- Max your Roth IRA ($7,000/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 vendor list. Connect with 403bwise.org for advocacy tools and sample letters. Some states have passed legislation requiring at least one low-cost index fund option in school district plans. If you coordinate with colleagues, many school districts have successfully added Fidelity or Schwab as plan options after employee pressure.
TIAA: the most common 403(b) provider
TIAA (Teachers Insurance and Annuity Association) is the largest 403(b) provider, serving most universities and many school districts. TIAA products range widely in quality:
TIAA Traditional Annuity: A guaranteed interest account currently paying roughly 3 to 4% guaranteed (sometimes higher). This is unique to TIAA with no 401(k) equivalent. The guaranteed rate makes it a reasonable bond substitute for conservative investors. However, it has significant liquidity restrictions — withdrawing the full balance can require a Transfer Payout Annuity process spread over 84 months (7 years). Check terms carefully before relying on this for a rollover strategy.
TIAA-CREF Lifecycle Funds: Target-date funds at 0.25 to 0.40% expense ratios. Acceptable but more expensive than Vanguard (0.08%) or Fidelity (0.12%) target-date funds. If these 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 specific plan, these are your best option within TIAA — use them over the higher-fee annuity products.
TIAA Real Estate Account: A unique fund investing directly in physical real estate properties (not publicly traded REITs), with historical returns of 7 to 9%. Provides direct real estate exposure most retirement plans do not offer. Worth considering as 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 completely separate tax-advantaged retirement account with its own $23,500 contribution limit in 2026 — independent of the 403(b) limit.
Having access to both means government employees can potentially contribute:
- $23,500 to the 403(b)
- $23,500 to the 457(b)
- $7,000 to a Roth IRA
- Total: $54,000/year in tax-advantaged savings
The key 457(b) advantage: No early withdrawal penalty. You can withdraw from a 457(b) at any time after separating from the employer, regardless of age. This makes the 457(b) an excellent early retirement vehicle — better than the 403(b) for anyone planning to retire before 59.5.
Priority for government employees with both: (1) Contribute to each plan up to the employer match. (2) Max the 457(b) before the 403(b) for its flexibility and early withdrawal advantage. (3) Max the 403(b). (4) Max the Roth IRA.
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 (usually best — maximum investment choice and lowest fees), roll to a new employer’s 403(b) or 401(k), leave in the old plan temporarily, or cash out (avoid this — income tax plus 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 process spread over 84 months, or a lump-sum transfer with penalties. Check your specific TIAA account terms and plan documents before making any rollover decision involving TIAA Traditional.
Frequently Asked Questions
Can I have both a 403(b) and a Roth IRA?
Yes — contributing to a 403(b) does not affect your Roth IRA eligibility. Only your income matters for Roth IRA eligibility (phase-out begins at $150,000 single / $236,000 married filing jointly in 2026). Having both is the standard recommendation for 403(b) participants: use the 403(b) for the employer match and tax deduction, then max the Roth IRA at Fidelity or Schwab where you get excellent investment options at minimal fees. The 403(b) and Roth IRA have completely separate contribution limits ($23,500 and $7,000 respectively) and can both be maxed simultaneously.
Should I choose Traditional or Roth 403(b)?
The same framework as Traditional vs Roth IRA applies. If you are in the 10% or 12% federal bracket, Roth 403(b) contributions are usually better — pay taxes now at a low rate, withdraw tax-free in retirement when your rate might be higher. If you are in the 22% bracket, Roth is still often advantageous for long-term savers expecting income growth. If you are in the 32%+ bracket, the Traditional 403(b) pre-tax deduction delivers meaningful current-year tax savings. The Roth option is not available in all 403(b) plans — check with your plan administrator if you do not see it as a contribution election option.
How do I find out what investment options my 403(b) offers?
Log into your plan’s online portal (ask HR for the website if you do not have it). Navigate to “investment options” or “fund lineup” and look for a list with expense ratios for each fund. If expense ratios are not displayed, ask HR or your plan administrator for the fee disclosure document — ERISA requires plans covered by it to provide fee information. You can also check 403bwise.org which maintains a database rating many school district 403(b) plans by investment quality and fee levels. If you see expense ratios above 0.50% on every available fund, you are in a high-fee plan and the Roth IRA should be your priority investment account.
What is the special 15-year catch-up provision?
The 403(b) has a unique catch-up provision not available in 401(k) plans: employees who have completed at least 15 years of service with the same eligible employer and who have averaged less than $5,000 in contributions per year historically may contribute an additional $3,000/year (up to a $15,000 lifetime maximum). This special catch-up is in addition to the standard $7,500 age-50+ catch-up, meaning some long-tenured employees can contribute up to $34,000/year ($23,500 + $7,500 + $3,000) depending on their history. The calculation is complex — ask your plan administrator to run the specific eligibility calculation for your service history.
What is the difference between a 403(b) and a 457(b)?
Both are tax-advantaged retirement plans with the same $23,500 contribution limit, but they serve different populations and have key structural differences. The 403(b) is for employees of schools, nonprofits, and hospitals. The 457(b) is for state and local government employees and some nonprofit employees. The critical distinction: the 457(b) has no 10% early withdrawal penalty after separating from the employer, regardless of age — you can access funds at 40 or 50 with no penalty. The 403(b) follows the standard 59.5 age rule. For early retirement planning, the 457(b) is superior if you have access to both. Government employees with access to both plans can contribute to each simultaneously for a combined $47,000/year in pre-tax savings.
Are 403(b) loans available?
Most 403(b) plans allow loans of up to 50% of the vested balance or $50,000, whichever is less — the same rules as 401(k) loans. The loan must be repaid within 5 years (longer for primary residence loans). If you leave your employer before repaying the loan, it may become due immediately or be treated as a taxable distribution plus 10% penalty. A 403(b) loan is generally a tool of last resort for genuine financial emergencies, not a routine financial planning tool. The borrowed amount stops growing in the market while the loan is outstanding, which has a real opportunity cost that is easy to underestimate.
Can I roll a 403(b) into an IRA?
Yes. When you leave your employer, you can roll your 403(b) balance into a Traditional IRA at Fidelity, Schwab, or Vanguard. This typically gives you the best outcome: complete control over investment options, lowest possible fees (Vanguard S&P 500 index fund: 0.03%), and no future dependency on your old employer’s plan choices. To execute a tax-free rollover, request a direct rollover (check payable to the new IRA custodian, not to you). If the check is made payable to you, 20% withholding applies and you must make up the withheld amount from personal funds within 60 days to avoid taxes and penalties on the withheld amount. The TIAA Traditional Annuity exception: this specific product may require a payout over 84 months — plan accordingly.
My school only offers annuity products. Is the 403(b) still worth contributing to?
Partially. If your employer offers a match, always contribute enough to capture the full match — even high-fee plans cannot negate the value of a 50% or 100% immediate return from matching contributions. Beyond the match, evaluate the fee level: if total fees are under 1%, continued 403(b) contributions make sense for the tax deduction. If fees are 1.5 to 2%+, max your Roth IRA first, then return to the 403(b) for additional contributions. At 2.5%+ fees (the worst annuity products), a taxable brokerage account with index funds may preserve more wealth than the 403(b) beyond the match threshold — the tax deduction partially offsets the fee drag, but not entirely at this level. Use the fee impact calculator above to see the exact breakeven for your specific situation.
The bottom line
The 403(b) is a powerful retirement tool for teachers, nurses, professors, and nonprofit workers — but it requires more vigilance than a typical 401(k) because of the prevalence of high-fee annuity products. Many participants quietly lose $100,000 to $200,000 over a career simply by accepting whatever investment options a plan representative recommends without checking the expense ratios.
The action checklist: contribute at least enough to get the employer match, check your plan for index fund options with expense ratios under 0.20%, avoid annuity products unless you have fully understood their total fees and surrender charges, max your Roth IRA at Fidelity or Schwab alongside your 403(b), and use the fee impact calculator above to quantify what you are paying.
