Take the following scenario: 1) Start a corporation in a tax-favorable jurisdiction (low to zero corp/cap gains taxes). Say LLC or the foreign equivalent, with you as the principal/owner, or however this is generally arranged. Caymans, Isle of Man, or wherever. 2) Open a brokerage account in the corporation's name, capitalize it, and trade U.S. markets through the account. 3) Money pot grows far faster than it would if Uncle Sam was skimming a bit off every one of your winners. 4) Whenever you want to 'repatriate' the profits, you declare a dividend distribution (to yourself) and pay full U.S. taxes on such. Report everything on U.S. tax forms as the law requires. Is this feasible? Is there any reason that it wouldn't work, or wouldn't be a good idea? Any obvious snags or pitfalls? Anyone actually done/do something like this? Under no circumstances do I want to do anything illegal, or have to rely on 'not getting caught.' And you don't need to say it, I know I can't rely on ET to keep me out of jail and need to consult lawyers and tax professionals before trying anything like what's described. Just gathering information.
