We all know that gambling income is heavily taxed in most of the countries. This is because most of the countries have separate taxes for the gambling related income. I want to know which are the most gambling friendly countries which charge very less or nil income tax on gambling winnings ?
If you ask this same question on Google, you did find what you are looking, I've actually searched and found some articles based on this topic and question you are asking, but then, I am not going to share the information here, since it's dated way back and due to the changing economy in different countries of the world, such information as this can not remain the same for ever, because, a country that was once tax free for gamblers must have turned around now to start taxing gamblers and their winnings, while other countries that used to tax gamblers might have stopped due to one reason or the other.
So, in the nutshell, I still don't even see how knowing this information can help a gambler, since it's not like a gambler is going to leave his country to travel to another country just for the sake not to pay gambling taxes, makes absolutely no sense to me, expect the gambler wants to go on a vacation and wants to travel to; and spend some time in a country where he gamble, win and not pay taxes on this wins, then may such gambler should come to Nigeria.
