It depends of they laws of the country where you stay. For example, my country requires me to pay taxes if I live there for more than 6 months a year (180 days)

It depends of they laws of the country where you stay. For example, my country requires me to pay taxes if I live there for more than 6 months a year (180 days). And theoretically you pay taxes where you live at that moment, but if you only stay for a month and them move to another then it is complicated, most people justify that they are on holidays there and pay taxes in their "usual" living country. I think most countries doesn't have laws to regulate this type of things.
