Social Security full retirement age for 1966

Federal law ties full retirement age to the year you reach 62. For people born in 1966 it is 67, which you will reach in 2033. Claiming at 62, in 2028, 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 1965 rule, which is also 67.
