A deferred compensation plan is another name for a 457(b) retirement plan, or “457 plan” for short.
Deferred compensation plans are designed for state and municipal workers, as well as employees of some tax-exempt organizations. The content on this page focuses only on governmental 457(b) retirement plans.
If you participate in a deferred compensation plan, you can contribute a portion of your salary to a retirement account. That money and any earnings you accumulate are not taxed until you withdraw them.
One major difference is that currently 457 plans are designed for public sector employees, and 401(k) plans are designed for private sector employees.
Another significant difference between these plan types concerns the application of the additional 10% early withdrawal tax.
