Matthew (48 at year-end) develops cutting-edge technology for SV Incorporated, located in Silicon Valley. In 2022, Matthew participates in SV's money purchase pension plan (a defined contribution plan) and in his company's 401(k) plan. Under the money purchase pension plan, SV contributes 15 percent of an employee's salary to a retirement account for the employee up to the amount limited by the tax law. Because it provides the money purchase pension plan, SV does not contribute to the employee's 401(k) plan. Matthew would like to maximize his contribution to his 401(k) account after SV's contribution to the money purchase plan.
