Wealth Tax: What It Is and Which Countries Levy One
Wealth taxes sit in a different category from the income taxes that drive most US paychecks. An income tax claims a share of what you earn each year; a wealth tax claims a share of what you hold. Several OECD countries levy annual wealth taxes today, with rates and thresholds that vary widely: Spain runs a tiered schedule with regional overlays, Norway combines federal and municipal rates, and Switzerland administers wealth tax entirely at the canton level. Belgium has a narrower 0.15% surtax on securities accounts. France's ISF was a true net-wealth tax until 2018, when it became the IFI, a real-estate-only levy. The United States has no federal wealth tax. Three states (California, Washington, New York) have introduced legislative proposals in the past few sessions, but none has been enacted. Washington's separate capital gains excise tax and Massachusetts's income surtax are sometimes lumped in with wealth-tax discussion; both are realization-based, not annual net-worth taxes. The two-tab calculator further down this page models annual wealth taxes and capital gains taxes side by side so the distinction is concrete.
Definition and mechanism
A wealth tax applies a rate or schedule of rates to the value of net assets above an exemption threshold, repeated every year. Net assets means gross assets (real property, securities, business interests, sometimes art and collectibles) minus debt secured by those assets. The annual valuation step is what makes wealth taxes administratively heavy: thinly traded private holdings and non-financial assets have to be revalued each year. Most enacted regimes set a high exemption (often above a million dollars or local-currency equivalent) so the tax only reaches a small fraction of households.
Which countries levy a wealth tax
Spain, Norway, Switzerland, and Belgium administer annual wealth taxes today. Spain's schedule runs from 0.2% to 3.5% above regional exemptions, with the central government's Solidarity Tax on Large Fortunes layered on top of communities that have reduced their own rates. Norway taxes net wealth above NOK 1.7 million at 1% to 1.1%. Switzerland's cantonal wealth taxes vary widely. Belgium runs a 0.15% surtax on securities accounts above EUR 1 million. Sweden, Finland, Austria, Germany, France (broad ISF), and the Netherlands previously had broad-based wealth taxes and have repealed or narrowed them.
US proposals and their status
The US has no federal wealth tax. Senator Warren's Ultra-Millionaire Tax Act and Senator Sanders's For the 99.8% Act proposed federal net-worth taxes on the largest fortunes; neither has advanced past committee. Constitutional scholars continue to debate whether an annual tax on net worth would require apportionment under Article I, which would make administration impractical. At the state level, California's AB-259, Washington's HB-1406, and a New York Assembly proposal each tried to levy a state-level wealth tax in recent sessions. None has passed. Washington's 7% capital gains excise tax above $262,000 is realization-based, not a wealth tax.
How wealth tax differs from estate, capital gains, and property tax
Estate tax is one-time, charged at death on a decedent's estate above the federal exemption (currently north of $13 million per individual). Capital gains tax is realization-based, charged when you sell an asset and recognize a gain. Property tax is asset-class-specific (real estate, sometimes business personal property) and assessed by a local jurisdiction. An annual wealth tax differs from all three: it applies every year, to the full base of net assets, regardless of whether anything was sold and regardless of whether you die. That is what makes it administratively unique and politically contested.
Annual Wealth Tax, charged every year on total net assets held, regardless of whether you earn income or sell anything. Norway, Spain, Belgium, and others use this model.

How to interpret the results
This page is designed for scenario planning, not for filing a return. Use it to understand the order of magnitude, compare jurisdictions, and learn which thresholds matter. Treat it as a research tool that helps frame questions for a tax adviser or legal review.
Where the uncertainty comes from
Wealth taxes are often full of exemptions, valuation rules, residency tests, treaty interaction, and asset-class carve-outs. That is why some entries are shown as reference-only policy context rather than a single simplified output.
