There are two types of defined-contributions plans: guaranteed contributions plans and salary deferral/matching contributions plans.Money-purchase pension plans and target-benefit plans include guaranteed contribution features, and the employer is mandated to make contributions to the plan each year. This makes the money-purchase and target-benefit plans more attractive than a profit-sharing plan, in which employer contributions are discretionary.
If there is a salary deferral feature, check to see if there is a cap on the amount that can be deferred. Also, if comparing two plans that provide matching contributions, pick the one offering the higher matching contribution amount.
