Let's take for example, Microsoft and Bill Gates' Foundation. At a glance you wouldn't suspect it for being a part of money laundering scheme to also avoid paying high taxes right? Wrong. US Federal Tax Law allows these people to get away scot-free with paying taxes if they donated it to charity. And they do donate it to their charity, but to their own charity instead, therefore still keeping the balances within their ball park. Another form of laundering these wealthy people commit is subjecting themselves to 1 dollar monthly salaries. As we all know salaries are tax-deductable and so being a CEO of a large company surely causes you to pay a lot of tax, well not if you subject yourself to 1 dollar payments. You take a dollar of payment every month and the rest of your salary goes towards "incentives like gift cards, travel vouchers, and the likes." effectively cleaning your money and also evading taxes at the same time.
