That would be a very high rate on property. If my million Euro house went up in value by €50k in a year I'd have to pay an extra €25k in tax or €15'750 at 1.5% on the new value of €1,050,000.An annual wealth tax (levied at the risk free rate of return times the rate of income tax) is a far better way to tax wealth, or less rigorously 1.5%
