Norway has a wealth tax of up to 1.1% of wealth, with discounts based on different types of wealth and a minimum deduction of ca. $150k. Discounts are based roughly on how liquid assets are. Houses etc. are valued at 25% of market value, so let's say you have a $600k house, the taxable value is $150k, which falls entirely within the minimum deduction, so most people pay very little wealth tax.
