A wealth tax is an annual tax on a person's total net worth — typically charged on the value of all assets (property, investments, bank accounts, business interests) minus liabilities. Unlike income tax (which taxes flows of money) or capital gains tax (which taxes specific sale events), wealth tax is levied simply for owning assets.
Most European countries experimented with wealth taxes in the 20th century but abolished them — finding they caused capital flight, administrative complexity, and raised relatively little revenue. Today, only a handful of countries maintain active annual wealth taxes. This guide covers which countries still have them, at what rates, and the key planning implications.
Between 1990 and 2020, most European countries that had wealth taxes abolished them. The key reasons:
For individuals with significant wealth, wealth tax jurisdiction matters enormously:

US Expat Wealth Reporting Help →No — the UK does not have an annual wealth tax and has never introduced one, despite periodic debate. The UK taxes wealth indirectly through: inheritance tax (40% on estates above ~£500,000); capital gains tax (10–24% on gains on disposal); stamp duty land tax on property purchases; council tax (a form of property-based annual tax, though it's relatively flat and not progressive by wealth). The Wealth Tax Commission (an independent research body) published a detailed proposal in 2020 for a one-time 5-year wealth levy as COVID debt relief, but this was never adopted. There is no current UK government proposal to introduce an annual wealth tax, though the debate recurs periodically.
Spain's wealth tax applies to residents on their worldwide net wealth. For a person with €5M net worth moving to Spain: the state wealth tax might be approximately €50,000–60,000/year (varying by autonomous community — Madrid previously offered a 100% rebate but the solidarity surcharge now applies regardless). For €10M+ net worth, the solidarity wealth tax at 3.5% on the top band creates a very significant annual bill. This is why wealthy individuals moving to Spain often establish residency in Portugal (no wealth tax), the UAE (no wealth tax), or carefully consider the structure of their assets (business exemptions may apply for operational businesses). Conversely, Spain's non-dom Beckham Law applies only to income tax, not wealth tax — expats using Beckham Law still face the normal wealth tax on Spain-situs assets.
France's original ISF (Impôt de Solidarité sur la Fortune) — which taxed net wealth above €1.3M at 0.5–1.5% — was abolished in January 2018 and replaced with the IFI (Impôt sur la Fortune Immobilière). The IFI applies only to real estate assets (not financial assets) above €1.3M at rates of 0.5–1.5%. This means a French resident with €5M in stocks and bonds pays 0% wealth tax on those financial assets (they were taxed under ISF at up to €75,000/year before). Only the real estate component of net wealth is now taxable under the IFI. The reform was a significant reduction for most HNW individuals and was credited with attracting some capital back to France.
The Netherlands Box 3 system taxes savings and investments on a deemed (notional) return rather than actual returns. The Dutch government set the assumed return at 4% when actual deposit rates were near 0% — meaning investors who held safe cash deposits were effectively taxed on returns they never received. The Dutch Supreme Court ruled in December 2021 that this violated the European Convention on Human Rights (right to property, no-discrimination). The government had to pay compensation to affected taxpayers and is redesigning the system. The new system (Nieuw Box 3 Stelsel) will tax actual returns from 2027. In the transition period (2023–2026), a more complex mixed approach applies. The episode is a cautionary tale about the difficulty of taxing unrealised/notional wealth.
For UHNW individuals (net worth £10M+) seeking to minimise wealth tax and other taxes: UAE (0% income, 0% CGT, 0% wealth tax, 0% inheritance tax — most comprehensive tax exemption globally); Monaco (0% income tax for most residents, no wealth tax, no CGT, no inheritance tax — but requires €500,000+ bank balance and Monaco property); Switzerland with lump-sum taxation in Zug or Nidwalden (minimal effective tax on large wealth when structured as lifestyle expenditure — CHF 400,000–600,000/year flat regardless of actual income); Singapore (low progressive income tax, 0% CGT, 0% wealth tax, 0% inheritance tax); Portugal (no wealth tax, no CGT on shares, IFICI for income — but 10% IHT equivalent stamp duty for non-direct heirs). The optimal choice depends heavily on lifestyle preferences, business activity, and family structure.
