I am going to be doing Air Force HPSP for a full 4 years scholarship. I am curious about how the pay works. First, is all of the "stipend" money taxable and reported on a W-2? Second, how many months out of the year am I paid the stipend, and how many weeks of active duty will I be paid for per year? What is the rough total of the pay/year? Third, when will the sign on bonus be deposited into my account?
