Eh - yes? What would be the problem with this? On a practical level, if this was implemented, I am sure the market would quickly create funds that payed out at exactly the right level to fund this. Here in Denmark, ETF's are always taxed this way and any losses can be carried forward. The one area where this can get problematic is things like a a big family business that is not providing enough profit to pay the tax. Such a business would end up getting liquidated, which makes sense from a free market perspective, but would make for some great "taxman killed family business"-headlines.
