List is as an AMT. Also, $10 million * 0.1% = 10,000$ which is a tiny tax bill at that wealth level.  If your paying less than 10k and have 10 million then somewhere something broke down.<p>IMO, you would need a much higher number. A 0.5% wealth tax AMT would = a 25% tax on a 2% ROI or 8.3% on a 6% ROI.<p>From an economic standpoint this is actually a good idea.  People with lot&#x27;s of unreolised income are often stuck with unproductive assets because selling them incurs a large tax bill.  With this you can sell a reasonable chunk of your assets without incurring extra tax.
