I was wondering about the whole tax return thing and the most benign explanation I could come up with is that Simon, as a devout Catholic, does not want to disclose the extent of his charitable giving, which is reputedly very generous. You're not supposed to advertise it (let not your right hand know etc.), so I'm guessing this might account for his reluctance to reveal the facts.

You may be right. Simon's father was practically a saint, and supported Catholic charities very generously. I have heard that Bill Simon takes after the old man.
