A paycheck can temporarily reduce Social Security payments if you're drawing benefits before your full retirement age. Getty Images By Kimberly Lankford, Contributing Editor September 27, 2017 QI retired two years ago and started taking Social Security benefits at age 62. I'm 64 now, and I've just been offered a part-time job at my local library. How much can I earn before it lowers my Social Security benefits? Also, is there an age when my earnings stop affecting my benefits?AYour earnings from a job can only affect your Social Security benefits until you reach full retirement age, which is age 66 for people born from 1943 through 1954. SEE ALSO: 10 Things You Must Know About Social Security Because you won't reach your full retirement age this year, you can earn up to $16,920 in 2017 with no impact to your benefits (the cutoff generally increases by a few hundred dollars each year). If you earn more than that, the Social Security Administration will withhold $1 in benefits for every $2 you earn over the limit. The cutoff is higher in the year you reach full retirement age. (See this table for the full retirement age by year of birth.) People who turn 66 in 2017, for example, can earn up to $44,880 until the month they reach full retirement age without affecting their Social Security benefits. The Social Security Administration will withhold $1 in benefits for every $3 in earnings above that level. Any money you make in the month you reach your full retirement age doesn't count toward the income test. And after reaching full retirement age, your paycheck won't affect your Social Security benefits at all. Advertisement Only wages from a job or self-employment count in this calculation. Income from investments, pension benefits and money withdrawn from an IRA or 401(k) are excluded.

The money withheld isn't lost forever. Instead, your benefits will be recalculated at your full retirement age and increased to make up for the months when your benefits were withheld. (Your additional work could also help increase your benefits, if it ends up being one of your highest 35 years of earnings. As long as you're working, the Social Security Administration will check your record to see if the extra wages could increase your monthly benefit.)
