Social Security full retirement age for 2004
Federal law ties full retirement age to the year you reach 62. For people born in 2004 it is 67, which you will reach in 2071. Claiming at 62, in 2066, 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 2003 rule, which is also 67.
