A 403(b) plan is a retirement savings account offered by certain employers—typically schools, hospitals, nonprofits, and religious organizations—that lets you set aside money before taxes are taken out of your paycheck. If your employer offers one, you may wonder how it compares to other retirement accounts, what you can contribute each year, or what happens to your money if you leave your job. This section answers common questions about how 403(b) plans work and what rules govern them.

The articles here explain contribution limits and catch-up options for older savers, the difference between traditional and Roth 403(b) accounts, how loans and withdrawals function, and what happens to your account when you change employers. You'll also find information about vesting schedules, investment choices, and how 403(b) plans differ from 401(k)s and IRAs.
