New comparability plans, sometimes referred to as "cross-tested plans," are usually profit sharing plans that are tested for nondiscrimination as though they were defined benefit plans. By doing so, certain employees may receive much higher allocations than would be permitted by standard nondiscrimination testing. New comparability plans are generally utilized by small businesses that want to maximize contributions for owners and higher paid employees, while minimizing contributions for all other eligible employees.

Employees are divided into groups based on valid business classifications, i.e., owners and non-owners. Each group may receive a different contribution percentage. For example, a higher contribution percentage may be given for the owner group than for the non-owner group, as long as the plan satisfies the nondiscrimination requirements.
