Most smart people who get substantial income will file both Federal and state returns whether or not they calculate that they owe taxes, in order to trigger the statute of limitations for audits. It sounds odd, still, that the accusation against him is one of not filing, rather than failing to pay taxes due, even though they believe the due amount is several hundred thousand.
It looks like he lost his home to foreclosure in 2009. If he couldn’t pay the note on the house, he probably didn’t pay all the taxes either.
