Casino winnings and Medicare rate. If your winning are too large, you may end up paying HIGHER monthly Medicare premiums. Well... those of us who live long enough to collect. This is more directed towards Slot Machine players, but if audited, which I have had an IRS agent in my business for two days in house audit... you better have the correct information for any... unreported income. That is another caveat. Nobody disputes Dice Influencing. I am not privy to any more information than the next experienced dice chucker. But.... What may be disputed is the massive winnings, much too often. Then the claims become a bit more... vague and cloudy.
