They say only two things are certain in life; death and taxes, but in this case taxes may work out to favour some of the young Raiders core. In the current location, players have a 13.3% state tax rate from California, which just so happens to be the largest in the country. When the team finally moves to Las Vegas, that entire 13.3% will be dropped due to Nevada not having a state tax.
Think about how much money that could save a player who is on $1million salary per year. Then think about how much that could save someone like Derek Carr, who is rumoured to be in the latter stages of agreeing a deal that pays him $25million per year (the highest in the league). Its no wonder that these contract talks may be taking longer than your average player, seeing as Carr will likely want to backload the majority of his deal for the projected 2020 move date and save himself millions.
Its not just Carr that will be doing this; Khalil Mack and Amari Cooper will likely be signing contracts near the top of their position pay level so will also bear in mind the potential gains of backloading their contracts. In fact, any player on the Raiders roster will be thinking about their contract length and pay if it can give them, in theory, an extra 13.3% of their salary per year once the move happens. Its also an interesting note when considering how the Raiders will fare in free agency once they move Las Vegas, but that talk can be tabled for another few years, sadly.
