April 20, 1983: President Ronald Reagan signs the Social Security Amendments of 1983, a set of sweeping changes aimed at shoring up the program's shaky financial footing drawn from recommendations of the National Commission on Social Security Reform (also known as the Greenspan Commission). Provisions include accelerating the scheduled payroll tax increase enacted in 1977; gradually raising the full retirement age (FRA) from 65 to 67; and making 50 percent of Social Security benefit income taxable for recipients with overall incomes above $25,000 for an individual and $32,000 for a married couple filing jointly.
