Found it. thanks N02L84ER. Darn It wipes out the entire amount.
"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. 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."
75,000\ 12 = $6,250 minus the $1,410 max gives me $4840
Then divide by 2,420 which is bigger then my entire monthly SS.
Yikes. I knew it was too good to be true. I'm sure there are lots of people who would love to have a part time gig like mine.
