After reading and pondering some of the comments in the Dream Homes thread I was wondering what were the tax implications if you stayed a few months in varying locations but never longer than the time required to be classed as resident in that country? I know US citizens pay tax on world wide income regardless, but for those of us more fortunate than to be hit with that what tax is paid where if you are not classed as resident in any one country? Or am I missing something obvious?
