Thailand, Dubai, UAE, Belize, Cayman Islands is suitable countries with 0% tax on trading. Then there is a bunch of countries with low tax on trading income, in Czech Republic it is 15%, in Sweden there exist a special insurance account type that are taxed at ~1% year for total amount.
My question was directed at this part of your post: "Some countries allow you to extend your tourist visa forever, one can stay as a tourist for serval years. This way of living is called PT (Permanent Tourist or Perpetual Traveler)"
Philippines is one country. You extend tourist visa in periods of 2 months. The cost of a 2 mo period is $44
I seem to remember there was an American trader doing just that in France (Paris) on Elitetrader and he had mentioned he only needed to show $20k in funds for the extension.
I have followed the PT-route for a few years. I haven't kept up well with the subject, but i did notice that countries like Costa Rica and Thailand, that were popular with PT's, started implementing the 180 days/year rule.
Rental income, investment income and capital gains of a non Portuguese source obtained by non habitual residents are also PIT exempt, provided the above mentioned conditions are met. http://www.pwc.pt/pt/fiscalidade/imagens/pwc_europe_best_kept_secret.pdf
Does anyone have any knowledge about the popularity of these new rules? How many people live in Portugal seeking "shelter" in these rules?
It does not have to be popular, it should work like you think it should work. It is very simple: go to the portugese offices of Deloitte or PWC and let them ask the important questions to the tax administration. I would never go anywhere without a written confirmation about what will be excempt from taxes. You should never do it yourself, and never take for granted what you find on internet. If you consider to make this step it means you make big money, so paying for good advice can be cheaper than making the step based on wrong information. Advice from PWC: However, the information is general in nature and therefore we recommend that you seek professional advice before making any decision in this area.
I repeat my question: Does anyone have any knowledge about the popularity of these new rules? How many people live in Portugal seeking "shelter" in these rules? And to I am nobody: I'm not stupid and can handle my own tax issues, thanks.
