Wealth Tax by Country 2026: Where Your Net Assets Get Taxed
Wealth taxes sound simple: pay a percentage of your net assets each year, regardless of whether those assets generated income. In practice, they are among the most politically contentious, administratively difficult, and structurally leaky taxes that any country can impose. Yet several countries maintain them, and a growing political movement in the EU wants more.
Norway: the poster child for wealth tax persistence
Norway imposes an annual wealth tax on worldwide net assets for tax residents. The tax applies at both the municipal and state level, with a combined rate structure that has been adjusted several times in recent years.
As of 2026, the Norwegian Tax Administration applies a municipal wealth tax of 0.35% and a state wealth tax of 0.65% on net assets exceeding NOK 1,900,000 (approximately EUR 165,000), for a combined rate of 1.0%. For net assets above NOK 21,500,000, the state rate increases to 0.75%, bringing the combined rate to 1.1%. The municipal share has been deliberately reduced in recent years (halved over two budget cycles), with the state absorbing the corresponding increase.
What counts as taxable wealth: real estate (assessed at a discount to market value, 25% of market value for primary residences up to NOK 14 million, with the portion above NOK 14 million valued at 70%), secondary properties valued at 100% of market value since 2023, financial assets (stocks, bonds, bank deposits at full value), business assets, vehicles, and other property. Debt is deductible. The valuation discounts on real estate and unlisted business shares are significant: they mean the effective tax rate on a diversified portfolio heavy in Norwegian real estate and closely held businesses is lower than the headline rate suggests.
Norway's wealth tax has a notable political consequence: high-profile departures. Several prominent Norwegian billionaires and business owners relocated to Switzerland in 2022-2024 after the wealth tax rate was increased. The government has responded not by lowering rates but by proposing exit tax provisions that would tax unrealized gains upon emigration, and by introducing a new permanent deferral scheme allowing taxpayers to defer wealth tax payments for up to three years when the tax exceeds NOK 30,000. The political calculation is clear: the revenue from the majority who stay outweighs the revenue lost from the minority who leave.
Spain: regional variation creates planning opportunities
Spain's wealth tax (Impuesto sobre el Patrimonio) applies to net assets of tax residents worldwide, with rates and exemptions that vary by autonomous community. The national framework, administered by the Agencia Tributaria, sets rates ranging from 0.2% to 3.5% on net assets above EUR 700,000 (with an additional EUR 300,000 exemption for the primary residence).
However, autonomous communities can modify rates and exemptions. Madrid historically offered a 100% rebate, effectively eliminating the wealth tax for residents. This ended in late 2022 when the national government introduced the Solidarity Tax on Large Fortunes (Impuesto Temporal de Solidaridad de las Grandes Fortunas) through Law 38/2022, published on December 28, 2022. This parallel tax applies at rates of 1.7% to 3.5% on net assets above EUR 3 million, specifically designed to capture wealth that escaped taxation through Madrid's rebate. The Solidarity Tax was upheld by the Constitutional Court in November 2023 and has been made permanent through subsequent extensions. A separate constitutional challenge to the Wealth Tax itself remains pending, with a decision expected in early 2026.
For international residents considering Spain, the wealth tax is a material consideration. A resident with EUR 10 million in net assets faces an annual wealth tax bill of EUR 100,000 to EUR 200,000 depending on the community and asset composition, on top of income tax on any returns those assets generate. The Beckham Law (special tax regime for inbound workers) does not exempt wealth tax, though it limits the scope to Spanish-source wealth for the first six years.
Switzerland: cantonal, not federal
Switzerland does not impose a federal wealth tax, but every canton levies one. Rates vary enormously. Zurich's combined cantonal and municipal wealth tax runs approximately 0.3-0.5% on high net worth. Geneva charges 0.5-1.0%. Zug, the famous low-tax canton, applies rates around 0.1-0.25%. Schwyz and Nidwalden offer some of the lowest rates in the country.
Swiss wealth tax applies to worldwide net assets for residents, including real estate, securities, cash, life insurance surrender values, vehicles, art, and other tangible property. Debt is deductible. Real estate is typically valued below market (assessed value or Steuerwert), which reduces the effective rate. Pension assets (second and third pillar) are generally exempt until distributed.
The Swiss Federal Tax Administration publishes cantonal tax comparisons, and the differences are substantial. A taxpayer with CHF 5 million in net assets pays roughly CHF 7,500 annually in Zug versus CHF 35,000 in Geneva. This variation drives internal migration within Switzerland and is a deliberate feature of the cantonal competition model, not a bug.
Colombia: emergency decree reshapes wealth taxation
Colombia imposes a wealth tax on individuals, and the rules changed significantly at the end of 2025. Under Legislative Decree 1474, issued on December 29, 2025, as part of an economic emergency declaration, the wealth tax threshold was lowered from 72,000 UVT to 40,000 UVT (approximately COP 2 billion, or about USD 500,000). The progressive rate structure now starts at 0.5% and rises to 5% for assets exceeding 2 million UVT. The DIAN (tax authority) assesses worldwide assets for Colombian tax residents.
The practical challenge in Colombia is asset valuation. Real estate is assessed using cadastral values that often lag market prices significantly. Financial assets held abroad present enforcement difficulties, though Colombia's participation in the Common Reporting Standard (CRS) for automatic exchange of financial information has improved the tax authority's visibility into offshore accounts. The emergency decree is subject to mandatory review by the Constitutional Court, adding uncertainty about whether the expanded rates will survive legal challenge.
Argentina: rates declining under 2024 reform
Argentina's personal assets tax (Impuesto sobre los Bienes Personales) was substantially reformed by Law 27,743, enacted in July 2024. The reform unified rates for domestic and foreign assets (previously, foreign assets were taxed at higher rates of up to 2.25%) and established a declining schedule: rates of 0.50% to 1.50% for 2023, decreasing to 0.50% to 1.10% for 2025, and 0.50% to 1.00% for 2026, converging to a flat 0.50% by 2027. The non-taxable minimum was raised from ARS 27 million to ARS 100 million, with annual CPI adjustments.
The reform also introduced a Special Advance Payment Regime (REIBP) allowing taxpayers to make a single advance payment covering fiscal years through 2027, with fiscal stability guaranteed until 2038. For both Argentina and Colombia, currency instability and inflation complicate wealth tax planning. Thresholds denominated in local currency erode in real terms, capturing more taxpayers over time without legislative action.
France: IFI remains focused on real estate
France eliminated its broad wealth tax (ISF, Impot de Solidarite sur la Fortune) in 2018, replacing it with the IFI (Impot sur la Fortune Immobiliere), which taxes only real estate wealth. The change was politically controversial and remains a live issue in French politics.
IFI applies to individuals whose net real estate assets exceed EUR 1.3 million. Rates are progressive from 0.5% to 1.5%. The tax covers directly held property, shares in property-rich companies (proportional to real estate value), and real estate investment trusts. The primary residence receives a 30% valuation discount. Financial assets, business assets (other than real estate), and most other wealth categories are exempt.
A proposal to replace the IFI with a broader "Impot sur la Fortune Improductive" (IFI-i), which would have expanded the tax base to include art, yachts, crypto assets, and other non-productive assets at a flat 1% rate, was voted through the National Assembly in October 2025. However, the Senate modified the proposal significantly, and the final version of the 2026 budget, adopted via the 49.3 procedure, did not include the reform. The standard IFI remains unchanged for 2026.
The narrowing from ISF to IFI was designed to stop capital flight (France lost an estimated EUR 200 billion in financial assets between 2000 and 2017 attributed partly to the wealth tax) while maintaining taxation of immobile real estate. The logic is sound: real estate cannot relocate to avoid tax, while financial capital can and does. Whether IFI generates enough revenue to justify its political costs is debatable: IFI raises approximately EUR 2.2 billion annually.
Countries that abandoned wealth taxes, and why
The list of countries that tried and dropped wealth taxes is longer than the list of countries that maintain them. Sweden abolished its wealth tax in 2007 after decades of capital flight, particularly to London. The Netherlands effectively abolished its wealth tax in 2001, replacing it with a presumptive return tax (Box 3) that taxes an assumed yield on net assets rather than the assets themselves. However, the Dutch Supreme Court (Hoge Raad) ruled in 2021 that the Box 3 system was discriminatory, and the Netherlands is now redesigning the regime to tax actual returns, bringing it closer to a conventional income tax on investment returns rather than a wealth tax.
Austria, Denmark, Finland, Germany, Iceland, and Luxembourg all had wealth taxes at various points and abolished them, generally citing the same problems: administrative cost of valuation, capital flight to countries without wealth taxes, and revenue that did not justify the economic distortions.
Cyprus: corporate tax rises to 15%
While not a wealth tax change, Cyprus enacted a comprehensive tax reform effective January 1, 2026, raising its corporate income tax rate from 12.5% to 15% in line with the OECD Pillar Two global minimum. The reform applies across the board to all Cyprus-resident companies regardless of size. Offsetting measures include reducing the Special Defence Contribution on dividends from 17% to 5% and abolishing stamp duty. For wealth structuring purposes, Cyprus remains competitive but the 12.5% rate that made it a default holding jurisdiction is gone.
Interaction with income tax and international structuring
Wealth taxes create unique planning pressures because they tax the stock of wealth, not the flow of income. An asset that generates no income (vacant land, art, gold) still triggers an annual tax liability. This means wealth tax jurisdictions effectively impose a negative real return on non-yielding assets, incentivizing either disposal or relocation of those assets.
For internationally mobile individuals, the interaction between wealth tax and income tax residency rules matters. Moving from a non-wealth-tax country (the UK, for instance) to Norway triggers an immediate annual liability on worldwide net assets. Moving in the other direction eliminates the wealth tax but may trigger exit taxes on unrealized gains. The sequencing of residency changes, asset restructuring, and tax treaty application requires careful modeling.
Wealth taxes also interact with double tax treaties in unexpected ways. Most treaties cover income tax and capital gains tax but do not cover wealth taxes. A Norwegian resident with real estate in the UK may face Norwegian wealth tax on that property with no treaty relief, on top of UK income tax on rental income and UK capital gains tax on disposal. True double taxation (not just double coverage) is a real risk in cross-border wealth tax situations.
Political momentum: where is this heading?
The EU Tax Observatory, an academic group affiliated with the Paris School of Economics, published a widely cited proposal for a global minimum wealth tax of 2% on billionaires. While this has no legislative pathway at EU or OECD level, it has influenced political discourse. Several EU member states have included wealth tax proposals in electoral platforms, and the European Parliament has passed non-binding resolutions expressing support for coordinated wealth taxation.
The practical barrier is unanimous consent. EU tax measures require unanimity among member states, and countries like Ireland, Luxembourg, and the Netherlands (which benefit from attracting mobile capital) have no incentive to agree. A coordinated EU wealth tax remains politically popular and legislatively impossible, at least under current treaty rules.
For high-net-worth individuals, the practical takeaway is that existing wealth taxes are more likely to increase than decrease, new wealth taxes are possible in countries with political momentum for them, and the global coordination needed to make wealth taxes truly inescapable does not yet exist. Plan accordingly, but do not assume the current map is permanent.
