I do not know the statute but I have spoken with 2 C.P.A.s both of which have told me that I will need to plan on paying 33% to 40% in state and federal taxes. I was also informed that once I receive the bonus check, I will need to make an estimated tax payment in the same quarter in which I receive the check in order to avoid any tax penalties. Apparently the lease bonus money falls into the category "rental income" and not capital gains.
