Quick Answer
A 403(b) is the nonprofit equivalent of a 401(k), offered by schools, hospitals, and tax-exempt organizations. Both have the same $23,500 contribution limit for 2026, but 403(b)s often have limited investment options (typically annuities) and fewer loan provisions than 401(k)s.

What is a 403(b) plan?
A 403(b) plan is a retirement savings plan available to employees of public schools, certain tax-exempt organizations, and ministers. Named after the tax code section that governs it, a 403(b) functions similarly to a 401(k) but serves the nonprofit sector instead of for-profit companies.
Key similarities: 403(b) vs. 401(k)
Both plans share these important features:
Example: Contribution impact on your paycheck
Whether you have a 403(b) or 401(k), the paycheck impact is identical:

Special 403(b) advantages
15-year rule catch-up:
Employees with 15+ years of service can contribute an additional $3,000 annually (lifetime limit of $15,000). This is unique to 403(b) plans.
Example: A teacher age 45 with 15 years of service could contribute:
What you should do
1. Maximize any employer match first — It's free money regardless of plan type
2. Review your investment options — Look for low-cost index funds or target-date funds
3. Compare expense ratios — Every 0.5% in fees costs you ~$50,000 over a career
4. Consider supplemental retirement savings — Many nonprofit employees also qualify for 457(b) plans
5. Use our paycheck calculator to see exactly how 403(b) contributions affect your take-home pay
Key takeaway: 403(b) and 401(k) plans have identical contribution limits and tax treatment, but 403(b)s typically offer fewer investment choices with higher fees, though some provide unique catch-up contribution opportunities.

Starting your career with a 403(b): What new nonprofit employees need to know
If you're new to the nonprofit world — whether as a teacher, hospital worker, or charity employee — your 403(b) works just like your friends' 401(k)s with a few key differences to understand.
The basics: Your 403(b) paycheck impact
Example: New teacher earning $45,000
Contributing 6% to your 403(b):
The math is identical whether you have a 403(b) or 401(k) — the difference is in your investment choices.
What makes 403(b)s different for new employees
Limited but simpler choices:
Instead of 30+ investment options, you might see 10-15. This can actually be less overwhelming when starting out, but make sure you have access to:
Watch out for high fees:
Some 403(b) plans still offer expensive annuity products with fees over 1.5%. A new teacher paying 1.5% vs. 0.1% in fees loses about $45,000 over their career on modest contributions.
Getting started checklist
1. Contribute enough for any employer match — Even 3% matching is $1,350 free money on a $45,000 salary
2. Choose a target-date fund if you're unsure about investments
3. Avoid annuities unless you fully understand the fees
4. Increase contributions with pay raises — Start at 6%, work toward 10-15%
Key takeaway: Your 403(b) works like a 401(k) with the same contribution limits, but focus on finding low-cost investment options to avoid high annuity fees common in nonprofit plans.
Key Takeaway: New 403(b) participants should focus on getting any employer match and choosing low-cost investments to avoid expensive annuity products.

403(b) strategies for high-earning nonprofit professionals
As a high-earning nonprofit employee — whether you're a hospital administrator, university professor, or nonprofit executive — your 403(b) can be part of a more sophisticated retirement strategy, often combined with other nonprofit-specific benefits.
The 403(b) + 457(b) combination advantage
Many nonprofits offer both 403(b) and 457(b) plans, allowing you to contribute to both:
2026 contribution limits:
This is significantly more than the typical $23,500 401(k) limit at for-profit companies.
Example: Nonprofit executive earning $200,000
Maximum retirement contributions:
If also eligible for pension:
Many nonprofits still offer defined benefit pensions, creating a three-legged retirement stool: 403(b) + 457(b) + pension.
Investment considerations for large balances
Expense ratio impact magnified:
On a $500,000 403(b) balance, a 1.0% expense ratio costs $5,000 annually vs. $500 for a 0.1% index fund. Over time, this compounds to hundreds of thousands in lost returns.
Self-directed brokerage options:
Some 403(b) plans offer brokerage windows, allowing access to individual stocks and ETFs beyond the standard mutual fund lineup.
Strategic considerations
Tax diversification:
Consider Roth 403(b) contributions if available, especially if your nonprofit work represents peak earning years before lower-income retirement.
Estate planning integration:
403(b) assets pass to beneficiaries outside probate. High earners should coordinate 403(b) beneficiary designations with overall estate planning.
Key takeaway: High-earning nonprofit employees can often contribute $47,000 annually across 403(b) and 457(b) plans — double the typical 401(k) limit — but should prioritize low-cost investment options given the long-term impact of fees on large balances.
Key Takeaway: High earners in nonprofits can contribute up to $47,000 annually across 403(b) and 457(b) plans, but should focus on minimizing investment fees on large balances.
