Depending on how much money you earn, you may not pay Social Security taxes on your entire income. That's because a cap is set each year on the amount of income subject to Social Security taxes. Last year, that limit was $118,500, but in 2017, it jumped to $127,200.
If you earn more than $15,720 (in 2016), Social Security will deduct $1 from your benefits for each $2 you earn over the threshold. In the year you reach full retirement age, you can earn up to $41,880 (in 2016) without having a reduction in benefits. However, if you exceed $41,880 in earnings, Social Security will deduct $1 from your benefits for each $3 you earn until the month you reach full retirement age.
