Lol. Sorry that's wrong. Most countries absolutely do and for sure almost every single one in Europe. Unless you are non tax resident in your home country, you still have to pay tax in your home country if the amount you have been taxed in Kazakhstan is below your normal rate in your home country. In Kazakhstan there is a 10% flat rate of tax on income. Therefore you still owe 15-35% tax on top of that depending on your citizenship and tax resident status. Is that a revelation?
