TL;DR:
- International wealth management must be strategic, integrating taxation, civil law and inheritance.
- Cooperation between multidisciplinary experts is essential for effective and sustainable optimization.
- Rigorous planning helps to avoid double taxation, exit tax, and major inheritance disputes.
Many expatriates and executives make the same initial mistake: they think that managing their wealth internationally is simply a matter of opening a foreign bank account or moving a few assets from one country to another. This is a simplistic and often costly view. The reality is far more strategic. Effective international wealth management simultaneously involves cross-border taxation, civil and inheritance law, legal structuring, and long-term family planning. This guide explains, step by step, the essential mechanisms, the most common pitfalls, and the concrete levers for securing and optimizing your wealth, wherever you are in the world.

Understanding international wealth management
International wealth management may seem complex, but a clear understanding of the fundamental principles helps to eliminate the main uncertainties.
By definition, this discipline goes far beyond simply holding assets abroad. It involves a comprehensive wealth management engineering integrating cross-border taxation, law and inheritance, with particular attention paid to each country concerned. The objective is not only to reduce the tax burden, but to build a coherent, robust and adaptable architecture over time.
Who is affected?
Three profiles are primarily targeted:
- Expatriates : seconded employees, internationally mobile executives, retirees living abroad.
- Leaders and entrepreneurs : those who hold stakes in several countries or are considering a sale of a business.
- Wealthy families : heirs with dispersed assets, blended families with heirs in different countries.
Each individual profile has its own regulatory constraints, wealth management objectives, and exposure to tax risk. This is why a tailored approach is essential.
The tools available
The international wealth guide lists several legal and financial vehicles adapted to these situations:
| Tool | Main use | Favorable countries |
|---|---|---|
| Holding | Business structuring, tax optimization | Luxembourg, Netherlands, Switzerland |
| Trust | Transfer, asset protection | United Kingdom, Cayman Islands, Singapore |
| SCI | Real estate ownership, split of ownership | France, Spain |
| Foundation | Philanthropy, family transmission | Liechtenstein, Austria |
| Family office | Global multi-asset management | Switzerland, United Arab Emirates |
| International assurance-vie | Capitalization, transmission | Luxembourg, Ireland |
Each tool operates according to a specific logic. An Anglo-Saxon trust does not have the same legal effects as a French SCI, and their combination can generate conflicts if not anticipated.
Pro tip: Before choosing a legal structure, carefully map your assets by country, their nature (real estate, financial, professional) and local inheritance laws. This mapping is the foundation of any coherent strategy.
A tailored approach is essential because international mobility creates hybrid situations: a tax resident in Switzerland with real estate in France and children in the UK must navigate three different legal systems. Without coordination, optimizations made in one country can create tax or inheritance complications in another.

International taxation: rules, risks and optimizations
Having seen who is involved and why, let us now address the essential foundation: taxation and its international implications.
Tax residency is the starting point for any strategy. It determines in which country you will be taxed on your worldwide income. Under French law, Article 4 B of the French General Tax Code (CGI) considers a person to be domiciled in France if they have their home or principal residence there, carry out their main professional activity there, or have the center of their economic interests there: a single criterion is sufficient. In the case of dual residency, the tax treaty distinguishes between the two countries in this order: permanent home, center of vital interests, habitual residence, nationality.
The most common mistakes
Here are the situations that most often generate unwanted double taxation:
- Maintaining the family home in France where the taxpayer declares himself resident abroad: France can claim tax residence if the spouse and children remain in the territory.
- Lack of formalization of tax departure : a poorly documented departure (home, activity, economic interests remaining in France) exposes one to a questioning of non-residence several years later.
- Income received in a third country not covered by a bilateral convention: they can be taxed twice without a compensation mechanism.
- Dividends from French companies received by a non-resident: they are subject to withholding tax in France, sometimes combined with tax from the country of residence.
How to avoid double taxation
THE bilateral agreements They provide three main methods to avoid double taxation:
| Method | Principle | Application example |
|---|---|---|
| Exemption with effective rate | The income is exempt in France but taken into account when calculating the rate applicable to other income | Income from properties located abroad, as a general rule |
| Tax credit equal to foreign tax | Tax paid abroad is deductible from tax owed in France, up to the amount of the latter. | Dividends and interest subject to withholding tax |
| Tax credit equal to French tax | The income is declared in France, but the corresponding French tax is neutralized. | Salaries and professional benefits, according to the agreement |
The applicable method depends on the type of income, the countries involved, and the applicable tax treaty. Poor planning can cost tens of thousands of euros in a single tax year.
Key points to remember: France is bound by approximately 125 tax treaties regarding income tax. But the existence of a treaty is not enough: it must also be applied correctly, at the right time, with the correct forms.
A well-constructed international tax optimization strategy always begins with an analysis of effective tax residence, followed by the identification of applicable treaties, before considering any restructuring.
Structuring, protecting and transferring one's assets internationally
Taxation is only one dimension: the structuring of assets must integrate other levers for protection and transmission.
Good asset planning before moving abroad follows a gradual approach. Methodological steps for expatriates include asset assessment, clarification of tax status, selection of suitable investments, the estate planning and asset diversification.
Key steps before and after expatriation
- Conduct a complete asset assessment : inventory of all assets (real estate, financial, professional), debts, beneficiaries and applicable matrimonial regimes.
- Clarify tax status in the host country and in France: date of departure, declaration of the year of departure (2042 for the period of residence, annex 2042-NR for income from French sources received afterwards), change of address in the Public Finances area, 2074-ETD if the exit tax applies.
- Choosing the appropriate legal structure depending on the objectives: SCI for French real estate, holding company for investments, Luxembourg assurance-vie for capitalization.
- Anticipating transmission : drafting or adapting one's will, checking compatibility with the inheritance law of the host country, considering a division of ownership.
- Diversify assets : do not concentrate assets in a single country or asset class to limit exposure to geopolitical and regulatory risks.
Structuring according to the situation
Wealth structuring tools vary depending on the individual's profile. A business owner who sells their company before moving abroad can contribute their shares to a controlled holding company before the sale, thereby deferring the capital gain on the contribution (Article 150-0 B ter of the French General Tax Code). If the holding company sells the shares within three years, it must reinvest 70% of the proceeds within three years in eligible activities and retain these assets for five years; wealth management and real estate rentals are excluded. Upon leaving France, the deferred capital gain becomes subject to the exit tax. A family with heirs in several countries can use a foundation or a trust to mitigate conflicts of inheritance laws.
“International wealth structuring is not a luxury reserved for the very wealthy. From €500,000 of net worth, the tax and inheritance implications of expatriation fully justify dedicated planning.” Alexis Sagnier, Balmont Conseil.
International succession is often the most complex issue. Regulation (EU) No 650/2012 subjects the entire estate to the law of the deceased's last habitual residence. Anyone can substitute the law of their nationality by making a declaration in a testamentary disposition, typically a will. This choice governs the civil devolution of the estate; inheritance tax remains determined by Article 750 ter of the French General Tax Code (CGI) and tax treaties.
Pro tip: If you own property in France and reside abroad, splitting ownership (transferring bare ownership to your children while retaining the usufruct) can significantly reduce inheritance tax while maintaining rental income. Consult a wealth expatriation advisor to validate the feasibility in your situation.
Special cases: risks, dual residence and pitfalls to avoid
Beyond the general rules, certain specific cases can call everything into question: let's discuss these mistakes to avoid.
The most complex situations are often those that appear simplest on the surface. An expatriate who keeps their family in France while working in Dubai can find themselves taxed in both countries simultaneously, with serious consequences.
The main risks to watch out for
- Dual tax residency : maintaining the family home in the country of origin, spouses in different countries, children attending school in France.
- Exit tax Article 167 bis of the French General Tax Code (CGI) applies to taxpayers domiciled in France for at least six of the ten years preceding their departure, whose securities are worth at least €800,000 in total, or who hold at least 50% of the profits of a company. Unrealized capital gains and deferred capital gains are recognized upon departure and taxed at 12.8% of income tax plus 18.6% of social security contributions. Deferral of payment is automatic, except in the case of departure to a non-cooperative state or to a state outside the European Union without a tax collection assistance agreement: in such cases, it must be requested, with guarantees, at least 90 days before departure. The tax is refunded after two years, or five years for assets exceeding €2.57 million, if the securities are still held. Declaration: form 2074-ETD.
- Wealth tax for non-residents Non-residents are liable for the French real estate wealth tax if their net real estate assets located in France exceed €1.3 million on January 1st. Shares in companies are counted for the portion of their value representing French real estate, and the usufructuary declares the property at its full ownership value.
- Forced heirship In many countries (the Middle East, Southeast Asia, and some Latin American countries), the law imposes minimum inheritance shares on forced heirs, regardless of the deceased's wishes. France itself has a system of forced heirship: when the applicable foreign law does not provide for it, the child entitled to a forced share can claim compensation from assets located in France.
- Geopolitical risk : political instability, exchange controls, nationalization of assets in some emerging countries.
Table of risks and solutions
| Risk | Triggering situation | Preventive solution |
|---|---|---|
| Double residence | Family remained in France | Formalize the tax departure, move the household |
| Exit tax | Starting with securities >€800,000 | Anticipate before departure, payment deferral |
| non-resident IFI | Preserved French real estate | Arbitrage towards assets outside the tax base (financial assets, real estate used for business purposes) |
| Forced heirship | Death in a country with a legal reserve | Will, trust, choice of inheritance law |
| Double taxation | Income without applicable agreement | Restructuring, vehicle change |
The pitfalls of double taxation are numerous and constantly evolving. Tax laws change, treaties are renegotiated, and what was optimal in 2022 may no longer be so in 2026.
“International wealth risks include dual residency, exit tax on capital gains, forced heirship and IFI for non-residents. Each of these risks can be anticipated with the right tools.”
The question of civil law versus common law also deserves particular attention. Article 792-0 bis of the French General Tax Code (CGI) subjects assets held in trust to inheritance tax upon their transfer, particularly upon the settlor's death: at the rate applicable to the degree of kinship when the beneficiary's share is determined, otherwise at 45% or 60%. The trustee declares the creation, modification, and termination of the trust, as well as, annually, the value of the assets (forms 2181-TRUST). To secure a international real estate investment, Knowledge of the local legal framework is essential. French notaries, as the notaries' resource reminds us, play a central role in coordinating international inheritance laws.
Why a multidisciplinary approach is key: what most people forget
After this overview of the pitfalls, a critical look back at the overall approach is necessary.
The temptation is strong to entrust your international wealth management to a single point of contact: a tax specialist, a lawyer, or a private bank. This is often a mistake. Each specialist optimizes within their own area, without necessarily seeing the side effects in others. A tax specialist who brilliantly reduces your tax liability in France may unknowingly create an inheritance problem in Spain or a reporting obligation in the United States.
Hybrid structures, such as a trust combined with a Luxembourg holding company, offer a level of protection that single-competency approaches cannot achieve. However, they require rigorous coordination between lawyers, tax specialists, asset managers, and notaries. Without this coordination, savings on one side are often offset by unforeseen costs on the other.
Family governance is another often overlooked aspect. For wealthy families with heirs in multiple countries, defining clear rules on the management of joint assets, voting rights in holding companies, and liquidity conditions is as important as tax optimization itself.
A truly multidisciplinary wealth management approach integrates these dimensions simultaneously. It's not about simply adding up expertise, but about fostering dialogue between different areas of expertise within a coherent strategy, regularly reviewed in light of legislative changes and the client's individual circumstances. This coordination is what distinguishes wealth management that withstands unforeseen events from a collection of disconnected structures.
