All, I have found myself in a situation where I need some clarification. I had recently graduated with my MS in atmos science. Additionally, I had more recently taken a job with a firm where my MS did not apply. I have found a job that does make use of my degree and where I would feel happier (current job is 100hrs a week and most of my off time is not even at home but in a hotel) With that said, the job I am in now gave me a sign on bonus and moving amt. The sign on bonus was taxed before being given (ie it was 5k and i netted 3k or so). The moving allowance was also such that they gave me a lump sum (1000 and then took taxes out of future earnings, ie as if I netted 1600 or so and received 1000) If I leave early, I have to pay back the bonus and moving allowance. My question is what amounts? 1) Would I have to pay back 5k in bonus and 1k in moving? 2) Would I have to pay what I netted? ie the 3k in the bonus after tax and the 1 k in moving? 3) If it is option 1, would it then be taken out of my w2 as earnings, effectively receiving the tax refund of 2k extra at the end of the year? Or am I off base somehow? Someone in HR or encountered similar situations have any guidance? Thanks!
