Expat taxation and wealth transfer in Switzerland: inheritance, gifts, foreign property, and wealth advisors

Expatriates accumulate wealth in two jurisdictions by design or accident. Some explicitly maintain homes in both countries (primary residence in Switzerland, property investment in home country). Others transition from one country to another and retain assets (Swiss resident with French property inherited or owned before emigration). Either way, the wealth becomes subject to overlapping tax rules that are neither coordinated nor intuitive for people trained in single-country planning.

Wealth taxation for residents with foreign assets

A Swiss resident domiciled in Geneva earning CHF 150,000 and owning French property worth EUR 500,000 is subject to Swiss wealth tax on both sources.

Swiss wealth tax (cantonal and communal, no federal wealth tax in most cantons): Varies by canton, typically 0.3-0.5% annually on net wealth above a threshold (e.g., CHF 100,000). A resident in Geneva with CHF 100,000 in bank accounts + CHF 500,000 in French property (approx CHF 510,000 equivalent) pays wealth tax on CHF 510,000 (or CHF 410,000 if the canton exempts the first CHF 100,000). At 0.4% rate, this is CHF 1,640-2,040 annually. Wealth tax is paid to the canton of domicile on all worldwide assets.

French property tax (taxes foncières): Levied on French real property by the commune where the property is located, typically 0.5-1.5% of cadastral value annually. A EUR 500,000 property in France (cadastral value often lower than market value, roughly 40-60% of market value) at EUR 250,000 cadastral value and 1% tax is EUR 2,500 annually. This tax is paid separately to the French authorities and is independent of Swiss wealth tax, it is not a "replacement" but an additional layer.

The combined wealth tax burden: A Swiss resident with French property pays both Swiss wealth tax (on worldwide assets) and French property tax (on the French property itself). This is double property taxation and is legal. Bilateral tax treaties do not eliminate this, they coordinate income tax, not wealth/property tax. For an expatriate accumulating wealth across borders, the property tax burden is higher than for a single-country resident.

The mechanism for avoiding or minimising this burden is limited. One approach: structuring foreign property ownership through a Swiss company (a structure where the Swiss company owns the foreign property, and the individual owns the company shares). The property is then owned by a corporate entity, not the individual, and may escape some foreign property taxes, but this adds complexity, requires annual corporate tax filing, and is only worthwhile for high-value properties. For most expatriates, accepting the double taxation is simpler than the legal and accounting complexity of a corporate structure.

Inheritance law: Swiss vs. foreign jurisdictions and forced heirship

An expatriate's death triggers simultaneous succession proceedings in multiple jurisdictions if they own assets in multiple countries. The rules differ fundamentally, creating planning challenges.

Swiss inheritance law: Uses the principle of equal partition among heirs. A Swiss resident with a spouse and two children who dies intestate (without a will) typically has their Swiss estate divided: spouse receives 50% (or 25% if there are both parents and children, but typically spouse + children situations result in spouse 50%), children share the remaining 50% equally. The Swiss legal system provides a "forced share" (legitimate portion) that cannot be disinherited: children have a minimum claim on the estate. A will can distribute freely disposable portion (roughly 50% of the estate), but the other 50% is automatic to heirs in fixed shares. Wills are changed frequently and should be updated every few years or after major life changes.

French inheritance law: Offers less flexibility for testamentary disposition. A French resident with a spouse and two children who dies can dispose freely of only 1/6 of the estate (because children have forced shares of 50%, spouse has minimum share of 25%, leaving only 1/6 freely disposable). The remaining estate is divided by operation of law: spouse receives 25%, children receive 50% (split equally), parents/siblings receive remaining share if applicable. This means the testator has very limited freedom to favour a specific heir or charity, the law mandates the distribution for most of the estate.

Multi-jurisdictional conflict: An expatriate domiciled in Switzerland with French property faces a conflict: which jurisdiction's succession law governs the estate? Swiss law would govern the Swiss assets and likely apply to succession overall (domicile-based rule). French law would govern the French property (property-location rule). If the deceased had two wills (one Swiss, one French), or if the Swiss will is silent on French property, conflict arises. Typically, the jurisdiction where the property is located governs that asset's succession, so French property is subject to French succession law even if the deceased was Swiss-domiciled and their main will is Swiss.

Planning implication: An expatriate with assets in multiple countries should have coordination between their jurisdiction wills or use a unified will structure where possible. Some jurisdictions (including Switzerland under certain conditions) recognise unified international wills. The coordination should be done by a specialist in both jurisdictions, not just a single Swiss notaire who may not understand French law implications, and not just a French notaire unfamiliar with Swiss requirements. The cost of coordination is significant but essential to avoid disputes, double taxation, and unintended distribution at death.

Gift and donation taxation: Switzerland vs. France

Gifts to children, spouses, and others are treated radically differently in Switzerland and France.

Swiss gift taxation (minimal or nonexistent): Most Swiss cantons have zero or minimal gift tax. Some cantons tax gifts above a threshold, but rates are low (typically 0.5-2% for close relatives, higher for distant relatives). The cantonal variation is significant, Genève has zero gift tax for direct descendants; Zurich has minimal gift tax. Lifetime gifts to children are essentially untaxed in Switzerland, making wealth transfer during life an effective strategy. An expatriate in Geneva can gift CHF 100,000 to each of their three children (CHF 300,000 total) with zero tax impact.

French gift taxation (substantial): France taxes gifts heavily, scaled by relationship and amount. Gifts to children between CHF 0-100,000 are taxed at approximately 5-10% (scaled); between CHF 100,000-200,000 at 15-20%; above CHF 200,000 at 40-60%. A CHF 100,000 gift to a child incurs approximately CHF 10,000 in French gift tax. A CHF 300,000 gift (total to three children) incurs CHF 50,000-80,000 in tax. French residents (and French-domiciled individuals) cannot avoid this by gifting, it is mandatory for gifts above certain thresholds. Spouses can gift freely (zero gift tax); direct descendants have exemptions (CHF 100,000 per child per parent every 15 years), but above these are taxed steeply.

Planning implication: An expatriate with significant wealth domiciled in Switzerland can gift more efficiently than a French resident, by timing gifts while Swiss-domiciled and using the minimal Swiss gift tax framework. However, if the recipient is French-domiciled, the gift may still trigger French tax in the recipient's hands (or the donor's, depending on treaty interpretation). This requires coordination with a tax advisor in both jurisdictions. Some expatriates plan large gifts to children while Switzerland-domiciled, before a potential return to home country, to lock in the lower tax burden.

Selecting and coordinating wealth advisors: bankers, notaires, and tax professionals

Swiss private banker: Manages Swiss assets (accounts, securities, funds, Swiss real property). Required for day-to-day wealth management, rebalancing, and tax reporting. A Swiss banker does not typically provide foreign property tax advice or multi-jurisdictional succession planning. Selection criteria: experience with expat clients, willingness to work with foreign advisors, understanding of Swiss-French or Swiss-[home country] bilateral rules. Cost: typically fees of 0.5-1.5% annually on assets under management, plus transaction costs.

Foreign notaire (France, Germany, Italy, etc.): Manages succession planning, property ownership, and legal documentation in the foreign jurisdiction. In France, a notaire is a government-licensed official (not just a lawyer) and handles property transfers, inheritance documents, and estate administration. Essential if you own foreign property. Selection criteria: experience with expat clients, bilateral treaty understanding, English fluency (if needed). Cost: typically hourly rates (CHF 200-400/hour) or flat fees for specific services (property transfer, will drafting).

Swiss tax advisor (multi-jurisdictional specialist): Not all tax advisors handle international situations. Essential: someone familiar with bilateral tax treaties, foreign asset reporting (FATCA, CRS, Common Reporting Standard), and succession tax implications. Standard Swiss tax advisors may not advise on foreign property tax or optimal timing of gifts across jurisdictions. Selection criteria: explicit experience with expat taxation, bilateral treaty knowledge, CRS/FATCA reporting familiarity. Cost: typically CHF 3,000-10,000 annually for ongoing advisory, plus project fees for specific planning.

Coordination necessity: The three advisors must communicate. The banker needs to understand what the notaire is planning for succession; the tax advisor needs to know what assets are where; the notaire needs tax-optimal structuring suggestions from the tax advisor. Without coordination, each advisor optimises their piece in isolation, missing opportunities and creating redundancy. The coordination cost is significant (additional meeting time, document sharing, cross-jurisdictional communication) but essential to avoid tax leakage and unintended outcomes.

Questions fréquentes

Do I pay tax on inheritance if I inherit property in Switzerland?

It depends on the canton of domicile. Some Swiss cantons (Lucerne, Appenzell) have no inheritance tax; others (Zurich, Genève) levy inheritance tax on certain heirs or above certain thresholds. Spouses and direct descendants often pay zero or low rates; distant relatives and unrelated persons pay much higher rates. The inheritance itself is free of income tax (you do not pay income tax on inherited assets), but the canton may levy a one-time succession tax. French inheritance is always subject to succession tax (unless exempt for spouses).

If I own French property and am domiciled in Switzerland, do I pay French property tax?

Yes, absolutely. French property is subject to French property tax (taxe foncière) regardless of the owner's domicile. You also pay Swiss wealth tax on the same property (as a worldwide asset). This is double property taxation. It is legal and unavoidable without selling the property or using a complex corporate structure. Budget for approximately 1% annually of the French property value in combined taxes.

Can I minimize gift tax by gifting to children while living in Switzerland?

Yes, if the children are also Swiss-domiciled or do not have other French tax obligations. Gifts are minimally taxed in Switzerland (0-2% in most cantons). However, if the recipient child is French-domiciled, the gift may trigger French gift tax even if the donor is Swiss-domiciled. Consult a tax advisor in both jurisdictions before executing large gifts across borders.

What happens to my Swiss and French assets if I die without a will?

Swiss assets pass by Swiss intestacy law (spouse and children inherit in fixed shares). French property passes by French intestacy law (forced heirship rules apply). If these rules conflict, both jurisdictions apply their own law to assets within their territory, so Swiss assets are divided by Swiss law, French assets by French law. This can result in different distribution percentages and create disputes. A coordinated will addressing both jurisdictions prevents this.
