"In the early 1990s, Trump scrambled to stave off financial ruin by not reporting hundreds of millions of dollars in taxable income by using a tax avoidance maneuver so legally dubious his own lawyers advised him that the Internal Revenue Service would most likely declare it improper if he were audited. He proudly acknowledges he did not pay a dime in federal income taxes for years on end. He insists he merely exploited tax loopholes legally available to any billionaire — loopholes he says Hillary Clinton failed to close during her years in the United States Senate. Thanks to this one maneuver, which was later outlawed by Congress, Mr. Trump potentially escaped paying tens of millions of dollars in federal personal income taxes."
