So, I stumbled across a post in the Off-Topic section and it got me to thinking. There has to be a flaw in my logic here somewhere but I just can't find it. Perhaps someone here can tell me where I'm wrong:
1) Americans pay taxes on world-wide income. Anywhere in the world, with just one (?) exception.
2) That exception is in Puerto Rico, a US Territory (not a state). Perhaps also in Guam, and US Virgin Islands, etc?
3) Because they are not states, they have no representation in Washington D.C. and we all know "No taxation without representation." Right? Therefore no taxation at the federal level; i.e. no federal personal income tax.
4) After 6 months, a US citizen is granted residency.
5) Therefore, it is possible to become a resident quickly and income earned there is not taxed at the federal level. Local Puerto Rico income tax is still applicable, of course. It is around 4%.
6) This will work for anyone who can earn money independent of their location (Think Internet, etc). They can re-locate their business and be in great shape, tax-wise.
One potential down side; you have to actually move and live there. But, it's an island in the Caribbean, so how bad can it be? Cost of living should be much lower than coastal USA.
