Defined-Contribution Plans

The Internal Revenue Code recognizes three mutually exclusive categories of qualified defined-contribution plans:

  1. Pensions (primarily money purchase plans), which have mandatory contribution formulas.(1)

  2. Profit-sharing plans, which have discretionary contribution formulas and distribute benefits strictly in cash. Profit-sharing plans can, in turn, be informally subdivided into three groups:

  3. Stock plans, which differ from profit-sharing plans only in that beneficiaries can demand payment in the form of the employer's securities.

Each type of plan can be further broken down by whether it offers a 401(k) feature; that is, whether it allows employees to make tax-deferred contributions to the plan. Although the vast majority of 401(k) plans are savings and thrift plans, money purchase plans and stock plans can also offer that feature.

Employers offering nonqualified defined-contribution plans have varying degrees of discretion in customizing their plans. For customization options see:

In addition to the subset of defined-contribution plans mentioned here, all defined-benefit plans can properly be called pensions.
