The structure of Swiss inheritance and gift taxes

Unlike many Western nations, Switzerland has no federal inheritance tax or gift tax. Instead, the legal authority to levy taxes on wealth transfers upon death or during lifetime rests entirely with individual cantons and municipalities. This cantonal sovereignty creates a highly competitive tax landscape across the 26 cantons, with substantial variations in tax rates, exemption thresholds, and administrative procedures.

As a general rule, the tax liability is determined by the last official domicile of the deceased, rather than the residency of the heirs. The main exception to this principle involves real estate: immovable property is always taxed in the canton where the land is located. Therefore, an expat residing in Zurich who owns a holiday apartment in Ticino will be subject to Ticino tax rules for the property and Zurich rules for all bank accounts and investment portfolios.

For expats building long-term wealth, understanding this cantonal structure is essential for effective estate planning. To see how cantonal tax differences impact broader wealth accumulation and asset location, see our guide on declaring foreign assets in Switzerland.

Cantonal exemptions for spouses and direct descendants

The most attractive feature of the Swiss estate tax framework is the widespread exemption for immediate family members. In all 26 cantons, transfers between spouses or registered partners are completely exempt (0% tax) from both inheritance tax and gift tax, regardless of the size of the estate.

Furthermore, direct line descendants (children, grandchildren, and adopted children) are exempt from inheritance and gift tax in almost all cantons, including Zurich, Geneva, Zug, Schwyz, and Basel-Stadt. A small number of cantons (such as Vaud, Neuchâtel, and Appenzell Innerrhoden) levy a modest tax on direct descendants, but rates are low and generous allowances apply.

However, tax rates escalate rapidly for transfers to non-direct relatives (such as siblings, nieces, nephews, or unmarried partners) and third parties. Unmarried cohabiting partners, in particular, face high tax brackets in many cantons, with effective tax rates ranging from 10% to 40%. Unmarried couples should explore structural solutions or lifetime transfers, and compare their wealth tax position using our Swiss wealth tax guide.

Gift tax rules and lifetime wealth transfers (Schenkungssteuer)

In Switzerland, gift tax (Schenkungssteuer) is closely tied to inheritance tax. Most cantons apply identical tax rates and exemption brackets to inter vivos gifts as they do to bequests upon death. This prevents individuals from avoiding eventual estate taxes by giving away assets shortly before passing away.

If you make a taxable gift to a friend or distant relative, the recipient is generally responsible for paying the tax. However, the donor can be held jointly liable under cantonal tax laws if the recipient fails to settle the tax bill. Certain cantons also mandate that gifts made within a specific timeframe (often 5 years prior to death) must be added back into the taxable estate for rate-calculation purposes.

Lifetime gifting remains a popular strategy for transferring real estate or business assets to the next generation. When making substantial gifts of property or equity, ensure you review the tax valuation rules in our imputed rental value and property tax guide.

Cross-border estate planning and international DTAs

For international expats, estate planning involves multi-jurisdictional complexities. When an expat passes away in Switzerland while holding assets, bank accounts, or real estate in their home country, dual tax liabilities can arise. The Swiss authorities may claim tax jurisdiction based on local domicile, while the foreign country may claim jurisdiction based on citizenship or asset location.

To mitigate double taxation, Switzerland has entered into specific estate and inheritance tax treaties with key countries, including the US, UK, Germany, Austria, Denmark, Sweden, and Norway. These treaties define primary taxing rights and provide credit mechanisms for foreign taxes paid. For US expats, US federal estate tax rules apply worldwide regardless of Swiss residence, requiring careful coordination with domestic exemption limits.

If you hold foreign property, securities, or foreign pension assets, you must check how foreign jurisdictions interact with Swiss succession laws. Learn more about treaty relief mechanisms in our double taxation agreements guide.

Swiss statutory forced heirship (Pflichtteil) & wills

In addition to tax considerations, expats must understand Swiss civil succession law. Swiss law enforces strict statutory forced heirship rules (Pflichtteil), which guarantee a fixed minimum portion of the estate to close relatives, primarily children and spouses. Under the revised Swiss succession law in force since 2023, the forced heirship portion for children was reduced to 50% of their statutory entitlement, giving testators greater freedom to dispose of their wealth.

Expats living in Switzerland have a valuable option under the Swiss Private International Law Act (PILA): you can elect in your will (Professio juris) to have the succession law of your country of citizenship apply to your global estate instead of Swiss law. This election is particularly useful for UK or US citizens who wish to bypass Swiss forced heirship restrictions and distribute assets freely to non-relatives or charities.

Ensure your Swiss accounts and pension assets are structured in accordance with your estate plan. For details on how pension capital payouts interact with estate law upon leaving or passing away, read our second pillar withdrawal guide.
