If I'm understanding the article correctly, the New York Times isn't counting the millions it found that Trump paid in alternative minimum tax over the years when making all its big, attention-grabbing viral claims about how little income tax he paid because technically alternative minimum tax is a different, seperate thing from income tax.
They make a huge deal about the difference between Trump’s “I paid millions in total taxes” and their “he paid a tiny amount in income taxes,” and I overlooked where AMT would fit in that distinction.
