I've been thinking to take my trading business more seriously, however I want to take to a different country. I am totally clueless as of legal basis for such move. Where do I start looking on what my tax considerations would be if say i traded out of eastern europe in US exchanges? do I have to establish a synthetic entity, and then get tax according to business law standarts, or in my particular case, the country's citizens aren't even required to file a tax return. Does that mean I can take 100% of my profits?
