Have you heard of dividend-arbitrage trading? Chances are you haven't. Even the Commodity Futures Trading Commission (CFTC) doesn't know much about it. It's not something that is common knowledge and those who are involved in it aren't about to spill the beans on how they do it. In essence, dividend-arbitrage trading is a way major banks help their clients minimize or avoid withholding taxes on stock dividends through a complicated series of trades involving futures contracts and other derivatives.
It does not pay to argue that you do not have to pay taxes to the US government. Many have tried to find 'loopholes' in the tax law to argue that they do not have to pay taxes. Do you know how many have won such arguments in court? None. Do you know how many have gone to jail adamant they do not have to pay taxes? All of them. Actor Wesley Snipes was perhaps the most famous of the lot.
