Applications for Social Security benefits can only be processed a maximum of four months before benefits are scheduled to begin. Thus, the earliest you can apply is age 61 and 9 months, and you can expect to receive your first payment four months later, the month after your birthday.
You can sign up for Social Security as early as age 62, but your benefit will be cut by 25% to 30% compared with what you'd receive at full retirement age. For people born after 1954, full retirement age gradually rises; for those born in 1960 and later, it's age 67.
