Wealth tax

A tax levied on the net value of a person’s or household’s assets, usually annually and after deducting liabilities. It differs from taxes on income, spending, or specific property transactions.

Net worth: The value of a person’s assets minus their liabilities. A wealth tax applies to this balance rather than to income earned during a period.
