Excerpt: The newly revealed tax information covers an earlier period of Mr. Trump’s business career. And The Times did not obtain Mr. Trump’s actual tax returns. But it obtained printouts from his official Internal Revenue Service tax transcripts, with the figures from his federal tax form, the 1040, from someone who had legal access to them. They represent the fullest and most detailed look to date at the president’s taxes. And they show that during a tumultuous decade of fevered acquisition and spectacular collapse, Mr. Trump’s core businesses — largely casinos, hotels and retail space in apartment buildings — ran up $1.17 billion in losses.
