A detailed guide explaining the 403(b) retirement plan, its advantages, and how it helps employees save for retirement.

What is a 403(b)

A 403(b) is a retirement savings plan designed for employees of public schools, non-profit organizations, and certain ministers to save for retirement through tax-advantaged contributions.

Key takeaway: The 403(b) functions similarly to a 401(k) but is limited to employees of educational and tax-exempt institutions.

Definition

A 403(b) is an employer-sponsored retirement savings plan that allows eligible employees to contribute pre-tax or after-tax income into investment accounts for retirement.

Why It Matters

The 403(b) plan plays a vital role in helping teachers, healthcare workers, and non-profit employees accumulate long-term retirement savings. It offers tax benefits, investment growth potential, and portability when changing jobs within the non-profit or public sector.

  • Contributions are tax-deferred (traditional) or after-tax (Roth).

  3. Investment Growth: Contributions grow tax-deferred until withdrawn.
  4. Employer Match: Some organizations offer matching contributions.
  5. Retirement Withdrawal: Taxes are applied upon withdrawal (for traditional accounts).
