Health Care Worker and First Responder Fairness Act This bill exempts from the Social Security Retirement Earnings Test (RET) wages earned through work as a health care professional or first responder during the COVID-19 pandemic. Under the RET, benefits are reduced for beneficiaries who are younger than full retirement age if they earn wages in excess of a specified annual limit. Further, the Social Security Administration may issue waivers to individuals employed as health care professionals or first responders during a declared public health emergency in which there is a shortage of health care workers. Wages earned by individuals granted waivers during a public health emergency are exempt from the RET.
