You apparently do not understand.  The income of S-corps is filed via "personal" returns of the shareholders.  Now Trump was likely both the salaried CEO of an S-corp and a shareholder.  As CEO he had a fiduciary responsibility to maximize profit to all shareholders not only himself.  You see the Politifact analysis is hopelessly shallow and does not examine or consider the complexities of the matter.  I say again.  As a shareholder of a S-corp, Trump would report company profit/loss on his personal return.  As CEO, of the S-corporation, he would have a fiduciary responsibility to maximize profit or minimize tax burden to all other shareholders.  With S-corp and LLC business profit/loss distribution the situation is grossly different from what you may have encountered as a salaried individual.

By the way, because of your comment I visited the Politifact website for the first time and felt like puking at how shallow it was and how packed with cheesy ads.
