The 10 European Countries That Should Give High-Net-Worth Families the Most Cause for Reflection

An independent assessment based primarily on the European Commission's 327-page study on wealth taxation.

Most people think about tax rates.

Successful entrepreneurs think about tax direction.

After reviewing more than 300 pages of the European Commission-commissioned study on wealth taxation, my conclusion is that the greatest long-term issue is not necessarily today's tax burden.

It is the direction of travel.

The report examines net wealth taxes, capital taxation, inheritance and gift taxes, exit taxes, international cooperation, automatic information exchange and the mechanisms that can make these systems more effective.

The following is my own ranking, based primarily on the themes, tax structures and case studies discussed in the report. It is not an official ranking by the European Commission or by the report's authors.

1. 🇪🇸 Spain

Overall Concern Rating: 10/10

Spain already has one of Europe's most comprehensive combinations of wealth-related taxes.

It has a recurrent net wealth tax, the Temporary Solidarity Tax on Large Fortunes, inheritance and gift taxation, an exit tax on qualifying unrealised gains, and extensive reporting requirements.

The report repeatedly uses Spain as one of its principal case studies and notes that Spain's top wealth-tax rate reaches 3.5%, the highest among the countries examined.

For a high-net-worth family, the important issue is not any one tax in isolation. It is the potential interaction of annual wealth taxation, inheritance taxation, capital-gains taxation and exit taxation.

2. 🇫🇷 France

Overall Concern Rating: 9.5/10

France no longer has a broad-based net wealth tax, but it continues to tax certain real-estate wealth, maintains significant inheritance taxation and has an exit-tax regime.

France also appears repeatedly in the report as an important historical and contemporary case study in the evolution of wealth taxation.

For internationally mobile families with substantial property, business interests or future succession issues, France deserves particularly close attention.

---

3. 🇩🇪 Germany

Overall Concern Rating: 9/10

Germany abolished its net wealth tax decades ago, but that does not remove it from the discussion.

The report repeatedly examines Germany in connection with inheritance taxation, exit taxation, valuation issues, constitutional constraints and the historical experience of wealth taxation.

For wealthy business owners in particular, Germany remains important because of the way business assets, succession and cross-border relocation can interact with the tax system.

---

4. 🇳🇴 Norway (not an EU Member State)

Overall Concern Rating: 9/10

Norway deserves inclusion because it operates one of Europe's best-known modern wealth-tax systems.

Although Norway is outside the EU, it provides much of the empirical evidence discussed throughout the report.

Norway also applies an exit tax to certain unrealised capital gains on shares, securities and investment assets.

For that reason, it provides a useful real-world example of how recurrent wealth taxation and exit taxation can coexist.

---

5. 🇮🇹 Italy

Overall Concern Rating: 8.5/10

Italy deserves attention because Italian tax residents can be subject to taxes on certain foreign financial assets and overseas real estate.

This is important for internationally diversified families because it illustrates how residency-based taxation can extend beyond assets physically located within the country.

The broader lesson is simple: holding assets offshore does not necessarily remove them from the tax system of the country where you are resident.

---

6. 🇳🇱 Netherlands

Overall Concern Rating: 8/10

The Netherlands is particularly interesting because of its evolving approach to taxing savings and investment wealth.

The report examines the Dutch Box 3 system, under which taxable income from savings and investments has historically been calculated using notional rather than actual returns, although recent court decisions have significantly affected how the system operates.

For wealthy investors, the Netherlands demonstrates how governments can develop alternatives to conventional realised capital-gains taxation.

---

7. 🇨🇭 Switzerland (not an EU Member State)

Overall Concern Rating: 7.5/10

Switzerland still levies cantonal wealth taxes and is one of the few European countries with a long-established recurrent net wealth tax.

Rates vary considerably between cantons, which makes Switzerland a particularly interesting example of tax competition within a single country.

The report also discusses how differences between regions can encourage wealthy taxpayers to relocate internally, and how centralisation or harmonisation may be used to reduce those differences.

---

8. 🇧🇪 Belgium

Overall Concern Rating: 7/10

Belgium is less significant because of a broad current net wealth tax and more because it sits inside the wider European system of international tax cooperation and information exchange.

The report repeatedly stresses the importance of automatic exchange of information, beneficial ownership records, third-party reporting and cross-border cooperation.

For wealthy families, this means that the relevant question is increasingly not only what taxes exist in one country, but how effectively information about assets can move between countries.

---

9. 🇦🇹 Austria

Overall Concern Rating: 6.5/10

Austria appears in the report primarily as an important historical case study.

Its past use of wealth taxation and capital levies illustrates how extraordinary fiscal measures can emerge during periods of severe national financial stress.

The historical lesson is not that Austria is about to reintroduce such measures, but that governments under fiscal pressure have repeatedly turned to accumulated private wealth as a potential source of revenue.

---

10. 🇬🇧 United Kingdom (outside the EU)

Overall Concern Rating: 6/10

The United Kingdom is no longer an EU Member State, but it appears regularly in the report's discussion of inheritance taxation, migration by wealthy individuals, capital taxation and behavioural responses to tax changes.

It remains particularly relevant because of the scale of its high-net-worth population and the importance of recent changes affecting long-term residents and internationally mobile taxpayers.

For wealthy families, the United Kingdom remains a jurisdiction where tax policy and residence planning deserve close and continuous attention.

So What's The Bigger Picture?

Ironically, I don't believe the biggest story is Spain.

Or France.

Or Germany.

The biggest story is that the distinction between individual countries may gradually become less important.

Throughout the report, the recurring themes include greater international cooperation, automatic exchange of financial information, beneficial ownership transparency, third-party reporting, digital tax administration, artificial intelligence, cross-border enforcement, exit taxes and post-emigration tax provisions.

Taken together, these developments point toward a future in which tax authorities may become increasingly capable of identifying, valuing and monitoring wealth across borders.

For internationally mobile entrepreneurs and investors, that may ultimately prove more significant than the tax rate in any single country.
