Goofy...the $10,000 IS THE TAX, as it must be returned to the Treasury. When it's returned, that a Tax Return.
LOL and please tell me, when exactly do I need to return my $10,000 to the treasury? Which agency, or court, is going to order me to do so?
It's borrowed money. If it does not return to the Fed before you die, it's collected afterwards. Eventually, it goes back to the Fed, because it's theirs, not yours.
