In Norway it's over 50% after everything is said and done..and this isn't include the 20% VAT that is paid on almost everything, the 1% "net wealth tax" (which includes real estate, cars, etc), and any other tax you might have to pay.
However, the neighboring Norway has a 1.1% combined wealth tax on income above about $350k. And according to [1] "from the income year 2008 the full market value of shares reg- istered on the stock exchange are in the shareholder’s wealth, whereas unlisted shares are valued based on the company’s taxable wealth".
Other countries that have the wealth tax are France, Switzerland, Liechtenstein, Netherlands and India. Some of them have limits on the wealth tax in place, e.g. in France the amount cannot exceed 50% of annual revenues.
"Taxable wealth is the value of the company's assets reduced by debt, as of 1 January in the assessment year."
This doesn't necessarily mean that the same definition applies at the tax office and/or that it applies to startups, though.
