ummm... you guys are talking about tax evasion. not judging it, but let's call a spade a spade. every strategy listed is 100% illegal, including daxscalper's. awesome you haven't been caught yet man, but if you do, the odds are high you will be majorly fucked.
to the OP: if you're an american, forget about it in your name. as a US citizen you're taxed on worldwide income regardless of residency. if you don't report and sign-up to a broker under a different nationality, you'll get fucked eventually. with the state of affairs in the world, now and going into the future, hiding income from governments will be an incredibly stupid thing to do. Risk: you lose everything and go to jail, Reward: you get to compound your 35%. I don't care how much you're making, that RR ratio sucks.
if your interest is to pay no taxes, only game in town for you is if you're a non-resident: you can trade through your wife's acct. just make sure you're not a resident in her country, or more than likely you'll owe there. oh, and if you really kill it in her acct, just be sure that you're 100% a dominant male and that she doesn't understand the value of money... if you're not and she does, look forward to becomming a eunuch.
