403(b)
403(b)
Quick Definition
A 403(b) plan is a tax-advantaged retirement savings account available to employees of public schools, colleges, universities, hospitals, churches, and other 501(c)(3) nonprofit organizations. It functions similarly to a 401(k) but is governed by different IRS rules and historically has offered a narrower selection of investment products.
What It Means
If you work as a teacher, nurse, university administrator, social worker, or employee of a nonprofit, your workplace retirement plan is almost certainly a 403(b). The name refers to the section of the Internal Revenue Code that authorizes these plans, just as "401(k)" refers to its own code section.
The core tax benefit is the same as a 401(k): contributions are made with pre-tax dollars, reducing your taxable income in the year you contribute. Investments grow tax-deferred, and you pay ordinary income tax only when you withdraw in retirement.
What makes 403(b) plans distinct is their history and regulatory environment. Until 2023, 403(b) plans were subject to fewer ERISA oversight requirements than 401(k) plans, which is why many 403(b) plans historically offered primarily annuity products rather than mutual funds. The SECURE 2.0 Act of 2022 brought 403(b) plans closer to parity with 401(k) plans, but differences remain.
How It Works
Contribution Limits (2025)
| Contributor | Annual Limit |
|---|---|
| Employee (under 50) | $23,500 |
| Employee (age 50-59, 64+) | $31,000 |
| Employee (age 60-63) | $34,750 (SECURE 2.0 enhanced catch-up) |
| Combined employee + employer | $70,000 |
The 15-Year Rule: A Unique 403(b) Benefit
Employees with 15 or more years of service with the same qualifying employer may be eligible for an additional catch-up contribution of up to $3,000 per year, with a lifetime maximum of $15,000. This benefit is exclusive to 403(b) plans and does not exist in 401(k) plans.
Eligibility check: You qualify if you have worked for the same public school system, hospital, home health service agency, health and welfare service agency, church, or convention/association of churches for at least 15 years.
Investment Options: The Annuity Problem
Historically, 403(b) plans were dominated by annuity products sold by insurance companies. This created a structural problem for participants:
| Investment Type | Typical Expense Ratio | Common in 403(b)? |
|---|---|---|
| Index mutual fund | 0.03% - 0.20% | Increasingly yes |
| Actively managed fund | 0.50% - 1.50% | Yes |
| Variable annuity | 1.00% - 3.00%+ (plus surrender charges) | Historically dominant |
| Fixed annuity | Varies | Yes |
Many teachers and nonprofit workers unknowingly paid 2-3% in annual fees through annuity products, dramatically reducing their retirement savings. A 2% annual fee on a $200,000 account costs $4,000 per year and compounds into hundreds of thousands of dollars in lost retirement wealth over a career.
What to Do
- Request the fee disclosure document (required by law under ERISA)
- Look for mutual fund options especially from Fidelity, Vanguard, or TIAA
- Compare expense ratios and choose the lowest-cost options available
- Consider rolling old 403(b) assets to an IRA when you change employers
403(b) vs. 401(k): Key Differences
| Feature | 403(b) | 401(k) |
|---|---|---|
| Who it covers | Public schools, nonprofits, hospitals | Private-sector employers |
| Contribution limits | Same ($23,500 in 2025) | Same |
| Employer match | Available but less common | Very common |
| 15-year catch-up | Yes (up to $3,000/year extra) | No |
| Investment options | Historically annuity-heavy, improving | Broad fund selection |
| ERISA oversight | Partial (churches exempt) | Full |
| Hardship withdrawal rules | Similar | Similar |
Roth 403(b)
Like the Roth 401(k), many 403(b) plans now offer a Roth option where contributions are made with after-tax dollars. Qualified withdrawals in retirement are completely tax-free, including all earnings. This is especially valuable for younger employees in lower tax brackets who expect to be in higher brackets in retirement.
Real-World Example: Teacher's 403(b) Over a Career
Scenario: Maria is a public school teacher, age 28, earning $52,000/year. She contributes 7% of her salary ($3,640/year) to her 403(b). Her school district matches 50% up to 6% of salary ($1,560/year).
Projections at 7% average annual return:
| Age | Years Invested | Maria's Contributions | District Match | Total Balance |
|---|---|---|---|---|
| 38 | 10 | $36,400 | $15,600 | ~$74,000 |
| 48 | 20 | $72,800 | $31,200 | ~$230,000 |
| 58 | 30 | $109,200 | $46,800 | ~$567,000 |
| 65 | 37 | $134,680 | $57,720 | ~$940,000 |
Maria's roughly $134,000 in personal contributions grows to nearly $1 million through the employer match and compound growth over 37 years.
Key Points to Remember
- The 403(b) is the retirement plan for education and nonprofit workers, with the same contribution limits as a 401(k)
- The 15-year service catch-up is a unique extra benefit for long-tenured employees
- Watch out for high-fee annuity products inside 403(b) plans; request fee disclosures and seek low-cost mutual fund options
- Employer matching is available in many 403(b) plans but is not as universally offered as in the private sector
- SECURE 2.0 (2022) gave 403(b) plans the ability to offer collective investment trusts (CITs), which are often lower-cost than mutual funds
Common Mistakes to Avoid
- Accepting the default annuity without reviewing fees: Always compare expense ratios across all available options.
- Not taking advantage of the 15-year catch-up: Many long-tenured employees are unaware this benefit exists.
- Leaving old 403(b) accounts behind: Consolidate old accounts into an IRA or new employer's plan for easier management and potentially lower fees.
- Not contributing enough for the employer match: Free money left uncollected is the most expensive retirement mistake you can make.
Frequently Asked Questions
Q: Can I have both a 403(b) and an IRA? A: Yes. You can contribute to a 403(b) up to the annual limit and also contribute to a Roth or traditional IRA (subject to income limits), effectively saving in two tax-advantaged buckets simultaneously.
Q: What if my employer does not offer a match? A: Many public school districts and nonprofits do not offer employer matching. In that case, contribute enough to lower your tax bill and maximize your own long-term growth. Also consider contributing to an IRA alongside your 403(b).
Q: Are church 403(b) plans different? A: Yes. Church plans are often exempt from ERISA, which means they have fewer mandatory disclosures and protections than plans covered by ERISA. If you work for a religious organization, verify whether your plan is ERISA-covered.
Q: Can I roll a 403(b) into an IRA when I retire? A: Yes. When you leave your employer or retire, you can roll your 403(b) balance into a traditional IRA (for pre-tax funds) or Roth IRA (for Roth 403(b) funds) without paying taxes, as long as you complete a direct rollover within 60 days.
