Lets say that Big Johnny can make 600,000 from trading and at that tax level he's taxed 34%. Say that Big Johnny has a son whose > 18 or a friend for that matter. Could he trade his friends / sons account 1/2 the time and his account 1/2 the time and make 300,000 for each account. Big Johnny will charge the other account a 1% fee, so big johnny will make 303,000 while little johnny will make 297,000, making a combined average tax percentage of say 27%. Is this legal?
