This is factually incorrect.
Here are some direct rebuttals:
NY times allegation: "In the 2017 fiscal year, FedEx owed more than $1.5 billion in taxes. The next year, it owed nothing. "
FedEx rebuttal: "FedEx has paid federal income tax every year, including fiscal year 2018."
NY Times allegation:" FedEx reaped big savings, bringing its effective tax rate from 34 percent in fiscal year 2017 to less than zero in fiscal year 2018, meaning that, overall, the government technically owed it money. But it did not increase investment in new equipment and other assets in the fiscal year that followed, as Mr. Smith said businesses like his would."
FedEx rebuttal: "Following passage of the Tax Cuts and Jobs Act (TCJA), FedEx invested billions in capital items eligible for accelerated depreciation and made large contributions to our employee pension plans"
Etc, etc, etc... These are literally the first few sentences from BOTH the article and the response. Either you're being intellectually dishonest by claiming that they didn't dispute and specific details or you're incompetent.
