None of the candidates are required to release thier tax information. And that's just the way it is.
It should be a law and Donald Trump's case points to a lot of problems that the American public should know about. Sorry, his application for president is incomplete.
Term limits in the house, and senate should be a law too. Because at the root of it; that's the cause of this election cycle being the debacle that it is.
But none the less the law is, what it is for now. Neither candidate is required to divulge thier tax information. Like it, or not; it's completely within the rules.
