Are you familiar with Controlled Foreign Corporation (CFC) laws?
In most cases, they are an obstacle that stands in the way between your offshore company and legal tax reduction.
So if you think you can have an offshore company and remain living in your high-tax home country, like the US or Australia - you are wrong.
CFC law is exactly a tool governments are using to prevent that from happening and the only solution is to move your private life offshore, together with your business and wealth.
