<prompt> Human: When I made 3000 a month, my federal income tax withheld was 65.42. When I made 3100 a month, my federal income tax was 215.38! I ended up with less net pay before I got the raise. Is there a reason for this? This was the months of January and February 2018, I get paid monthly a salary.  <response>: 65.42 on a 3000 paycheck is only 2, which is not nearly enough for federal taxes. So it sounds like something was set up wrong and they werent withholding enough before.
