Even if I'm in a country that is not mine Instead of me to keep such rules I will rather quit from gambling, though in my country such rules does not exist. In my country if you experience win definitely you will be paid just exactly the amount that is shown as the potential wining no one is going to remove anything from your wining, honestly if I happens to be in those countries where they tax gamblers definitely i won't even think of playing gamble anymore.
Yes, it's also a very valid solution It's always better to do so if you can avoid potential problems.
I don't pay taxes for gambling in my country , and even if my country's government Imposes them, I'm sure no one will pay them, since no one will give more money to a government like mine, mainly for that reason.
That's why I emphasize European countries, countries like the Nordic countries , and even Switzerland, where they manage a different economy and have more controlled regulation, If it's established that you have to pay taxes for gambling in a casino, I as a foreign citizen , must pay them because I must comply with those regulations of that country That's how it should be.
