I received a signing bonus from a company for 3k, unfortunately I won't be joining them after I graduate so I need to return it.
I was deposited a total of 2.2k after taxes, however when I asked about how to return the bonus they said they need a check for 2.6k.
I understand that something was withheld for taxes, but I don't understand how this is calculated. What is the 0.4k that I did not receive? Also, what is the 0.4k that I owe them? What will I receive in my tax refund?
Can someone explain this scenario?
