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.
Income Limits. In 2011, you can collect early Social Security and make up to $14,160 a year without penalty. For each $2 you earn over the limit, Social Security deducts $1 from your benefit amount. Once you reach the year of your full retirement age, yet before the month you reach full retirement, you can earn up to $37,680 without penalty.
