If you were to play FPDW with a 100.7% return how do the taxes on the royal flushes effect your EV. I cannot seem to understand if taxes put you in -EV or just takes a percentage of your winnings. My problem is that if you tax just the royal flush it lowers the value of the royal flush which could make the game -EV. But if you were to tax your net winnings it would only be taking a portion of your winnings still putting you in +EV. This is probably a simple problem, but i can't seem to come up with the answer.
