Full retirement age by birth year

Full retirement age is the Social Security age tied to the unreduced retirement benefit. It depends on birth year.

For people born in 1960 or later, full retirement age is 67.

SSA full retirement age is 66 for people born 1943 through 1954, rises in two-month steps for 1955 through 1959, and is 67 for people born in 1960 or later.

Neutral landscape

The shape of the question

SSA birth-year guidance is the source because full retirement age is not the same for every worker.

Source trail: SSA.gov

SSA delayed-credit guidance matters because credits are measured after full retirement age and stop after 70.

Source trail: SSA.gov

SSA earnings-test guidance matters because the full-retirement-age year has a separate exempt amount.

Source trail: SSA.gov

IRS Publication 915 matters because the claiming age changes income timing, while taxability depends on the tax formula.
