Social Security full retirement age for 1984
Federal law ties full retirement age to the year you reach 62. For people born in 1984 it is 67, which you will reach in 2051. Claiming at 62, in 2046, permanently reduces the monthly benefit; waiting past full retirement age increases it. Social Security considers you to reach an age the day before your birthday, so January 1 birthdays follow the 1983 rule, which is also 67.
