<prompt> Human: Hey guys, I am working my first job 75k a year with this year including a 3k relocation bonus and my second pay stub is difficult to make sense of. I worked 80 hours for the pay period at 36.0578 hr and received my relocation bonus of 3000. The bonus, I believe, is 3000 gross to me, so I guess the line called Relocation Gu at 4454.31 is correct.So- YTD regular earning is 5769.25 so far plus 4454.31 for relocation for a total of 10223.56. My Federal Income Tax for this pay stub is 521.48, 2006.85 YTD, which I absolutely cannot figure out how they got. Then my social security tax is 174.21 this stub, with 629.23 YTD. And medicare tax is 40.74 with 147.16 YTD. Dental Insurace is 7.5, Health Insurance is 62.77, Vision is 4.45 for a grand net payment of 2073.47. The part I am really confused by is the Federal Income tax. Is it different because of my bonus this pay period, or will it always be 521.48 every two weeks? The reason I ask is because the take home pay for the first set of two weeks was 2292.16 and now it is 2073. What gives? The first two weeks didnt include those insurance costs, but that doesnt bring the value down enough to match up...did I change tax brackets? I tried computing that too but it didnt work.  <response>: The part I am really confused by is the Federal Income tax. Is it different because of my bonus this pay period Most likely. Bonuses are often withheld at a higher rate than normal income, but that doesnt mean you pay higher taxes on them. It will be settled when you file your taxes next year.
