Age 66
Those born between 1943 and 1954 are eligible to receive their full Social Security benefit when they turn 66. The Social Security full retirement age gradually increases by a few months for every birth year. For instance, from 66 and two months to 66 and 10 months for those born between 1955 and 1959. If you were born in 1957, your full retirement age is 66 and six months. Only then you can claim your entire Social Security benefits without Uncle Sam withholding any of your payments.
