Trumps lawyer apparently told the judge that the son's homes are apparently owned by trump org LLCs, they just happen to live in them. So they get to take big business deductions on where they live. How is that accounted for in their personal taxes? Are they paying rent to trump llc? Or do they live in these places rent free? Do they report in their taxes the monetary benefit of living in a trump org llc owned property rent free as an income item? Likewise trump basically lives full time at maralago, and that's a country club business.
That’s not how they see it though.
