This week’s question comes from Elizabeth, a small-business owner. We just hired a part-time employee who is seventy years old. He’s already collecting social security benefits so I’m not sure if I should still withhold it from his wages. At what age does social security withholding stop? Answer: There is no age beyond which employers are no longer required to withhold social security or Medicare taxes, which are also known as FICA or OASDI. Employers must continue to withhold social security and Medicare taxes and pay the employer’s portion even if the employee is collecting social security or is eligible for Medicare. The Social Security Administration will recalculate benefits and may increase them after retirement if the additional earnings result in a benefits increase.
