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 2017, this limit on earned income is $16,920 ($1,410 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.
