Which of the following is not a type of retirement plan?

The correct answer is that 414(h) is not a type of retirement plan. A 414(h) refers to a specific section of the Internal Revenue Code that allows certain governmental employers to make contributions to a qualified retirement plan for employees through salary reductions, typically for purpose of retirement funding. However, it does not represent a standalone retirement plan option; rather, it provides guidelines for plan operations and contributions.

In contrast, a 403(b) is a retirement plan designed for employees of public schools and certain tax-exempt organizations, allowing them to contribute to retirement savings on a tax-deferred basis. A 457 plan is a type of non-qualified deferred compensation plan available for governmental and certain non-profit organizations. An IRA, or Individual Retirement Account, is a savings account with tax advantages that individuals can use to save for retirement. Each of these options represents distinct types of retirement plans or accounts designed to help individuals save for their retirement, while 414(h) serves more as a regulatory framework for employer contributions.
