<prompt> Human: Alrighty so my friend and I are both the same age, work the same job and make close to the same pay. His gross was 69k and I made 62k as he had way more OT than I do.We are both using turbo tax and after entering the basic information he has his federal refund at 3k and I have mine at 1.2k The only difference between him and myself is that he has a child. But he did not claim his child on his taxa because his girlfriend is. So Im curious as to what could cause the big difference between his federal refund and mine?I realize there is probably a lot more involved than what I have given in information but getting more back on my refund would be nice.  <response>: Different withholdings combined with different tax liabilities. Refunds are meaningless
