how much can one earn when on social security
If you are under full retirement age for the entire year, we deduct $1 from your benefit payments for every $2 you earn above the annual limit. For 2017, that limit is $16,920. In the year you reach full retirement age, we deduct $1 in benefits for every $3 you earn above a different limit. In 2017, the limit on your earnings is $44,880 but we only count earnings before the month you reach your full retirement age.
