What is full retirement age for Social Security?
The full retirement age, depending on your year of birth, varies between 66 and 67 years old.
If you were born between 1943 and 1954, your full retirement age is 66. If year were born later than that, your retirement age will rise by two months for every year past 1954 that you were born in. For example, a worker born in 1956 would reach full retirement age when they were exactly 66 years and four months old.
The maximum full retirement age is 67 years old, no matter how long after 1954 you were born.
