Eligible Employers
403(b) plans are available exclusively to employees of:
- Public schools, colleges, and universities (government entities)
- Tax-exempt organizations under IRC Section 501(c)(3) (hospitals, charities, foundations)
- Religious organizations and churches (church plans may have additional ERISA exemptions)
- Ministers (including self-employed ministers meeting specific requirements)
Employees of for-profit organizations, even those with nonprofit affiliates, are not eligible for 403(b) plans. For-profit hospital systems or universities that are not themselves tax-exempt must use 401(k) plans.
Tax Treatment
- Traditional (pre-tax) 403(b): Contributions reduce taxable income in the year made; investments grow tax-deferred; distributions taxed as ordinary income; 10% early withdrawal penalty before age 59½ (exceptions apply).
- Roth 403(b): After-tax contributions; tax-free growth; qualified distributions tax-free; no income limit (unlike Roth IRA). Since SECURE 2.0, no RMDs during the owner's lifetime.
- RMDs: Required beginning at age 73 (increasing to 75 for those born 1960 or later) for pre-tax 403(b) accounts.
