At my current job, my hourly rate is $12.50, and last week I worked 35.25 hours. This is supposed to translate into $440.63 before taxes. However, on my payroll history it shows a gross amount of $461, which is about $21 more than I was supposed to get. This happens every paycheck. Why is the gross amount always higher than what I'm supposed to get??
Additional information that might be relevant:
-I'm a temporary contract employee employed by a staffing agency
-Last year 15% of my earnings were automatically withheld for federal income, social security, and medicare, but after tax returns, I paid approximately 5% in taxes (I made very little money).
-I do not have any special circumstances (no investment accounts, child support, etc.) I'm just a recent college grad.
