Senior Citizens' Freedom to Work Act of 2023 This bill eliminates provisions that reduce Social Security retirement benefits for certain beneficiaries who are younger than full retirement age and who have outside income above a certain threshold, also known as the Retirement Earnings Test (RET). Under the RET, benefits are reduced for beneficiaries who are younger than full retirement age if they earn more than the annual limit ($21,240 for 2023). Withheld benefits are subsequently added to monthly benefits once the beneficiary reaches full retirement age.
