I live in a country with a 1.3% wealth tax (the Netherlands), but as long as you own more than 5% of a company it doesn't apply to that part (a bit more complicated than that, but effectively this is what happens). The wealth tax does apply once it's cash, so dividends you received, or proceeds from selling (part of) the company. I would imagine a wealth tax in the US could do the same thing.
