If there is such an opportunity, most people will not pay the tax on gambling winnings on their own. The only way to force a player to pay tax will be if the casino charges you after winning and then transfers it to the budget.
That's true, I mean who likes to pay tax on gambling or anything at all ? Its another way of the government actually extorting gamblers and their citizens in general. Thankfully my country doesn't amount for such rules but notwithstanding if am forced to pay taxes on my gambling i guess I would have no choice but to comply moreover it will not be more than 5-10% of our winnings.
