Hello binha,
With the amount of money you are talking about, there really is no way to save significantly in taxes. If you are a single taxpayer, once you reach an adjusted gross income of $357,700 for the year, anything over that is automatically taxed at 35%. So no matter how much you would ask for as a signing bonus in any given year, or how much of a salary in any given year, unless you were to spread out the $60 million over a period of 30 years, your tax difference would be minimal.
The main tax advantage that you might have is your state of residency. There are currently 7 states that do not impose a state income tax - Florida, Texas, Alaska, Nevada, South Dakota, Washington and Wyoming. Considering that an average state tax could cost you around 5 to 6% per year, that would be a significant savings if you could make one of those states your state of residency.
