David Fahrenthold's latest shows that Trump is likely a criminal tax-evader as well as a self-dealer:
Donald Trump’s charitable foundation has received approximately $2.3 million from companies that owed money to Trump or one of his businesses but were instructed to pay Trump’s tax-exempt foundation instead, according to people familiar with the transactions.
In cases where he diverted his own income to his foundation, tax experts said, Trump would still likely be required to pay taxes on the income. Trump has refused to release his personal tax returns….
The laws governing the diversion of income into a foundation were written, in part, to stop charity leaders from funneling income that should be taxed into a charity and then using that money to benefit themselves. Such violations can bring monetary penalties, the loss of tax-exempt status, and even criminal charges in extreme cases.
