The Bronx recently saw the end of a major tax fraud case involving a man dubbed “the Magician,” who used calculated deceit rather than tricks to commit the crime. Rafael Alvarez, the CEO, and manager of a high-volume tax preparation company ATAX, has pleaded guilty to charges involving one of the largest ever tax frauds perpetrated by a tax return preparer, according to the U.S. Attorney’s Office for the Southern District of New York.
