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.
Limits on Earned Income If Claiming Early Benefits. Until you reach full retirement age, Social Security will subtract money from your retirement check if you exceed a certain amount of earned income for the year. For the year 2016, this limit on earned income is $15,720 ($1,310 per month). The amount goes up each year. If you are collecting Social Security retirement benefits before full retirement age, your benefits are reduced by $1 for every $2 you earn over the limit. Once you reach full retirement age, there is no limit on the amount of money you may earn and still receive your full Social Security retirement benefit.
