Cantonal Differences in Inheritance Taxation in Switzerland
The Swiss federal system grants the 26 cantons broad fiscal autonomy, particularly in the area of successions. This specificity creates a complex regulatory mosaic requiring in-depth understanding of inter-cantonal differences. Variations concern both tax rates and exemptions, allowances and the treatment of heirs according to their degree of kinship. Succession planning in Switzerland therefore requires precise knowledge of cantonal particularities to optimise wealth transmission and avoid tax surprises for heirs.

Territorial Principle and Multi-Canton Estates
The territoriality principle governs inheritance taxation: real estate is taxed in the canton where it is located, while movable assets are generally taxed in the canton of the deceased's last domicile. This rule can generate complex situations when assets are distributed across several cantons, potentially subjecting an estate to several different cantonal tax regimes simultaneously.
Notable Cantonal Particularities
- The canton of Schwyz taxes no inheritance whatsoever, regardless of the relationship with the deceased
- The canton of Obwald grants particularly generous exemptions
- The canton of Geneva provides substantial allowances but high progressive rates for more distant heirs (up to 54.6%)
- The canton of Valais applies a system based on the inheritance share
- The canton of Neuchâtel is the only French-speaking canton to tax successions even between spouses
An effective change of domicile to a fiscally advantageous canton can significantly reduce the inheritance tax burden on movable assets. PBM Avocats advises on inheritance tax planning strategies tailored to the specific cantonal context in Geneva and Lausanne.
Frequently Asked Questions about Cantonal Differences in Inheritance Taxation
Which Swiss cantons impose no inheritance tax regardless of the family relationship?
The canton of Schwyz is the only one to exempt all inheritances, regardless of the family relationship between the deceased and the heir. The canton of Obwald also does not tax inheritances. These two cantons represent a notable exception in the Swiss tax landscape.
Why does the canton of Neuchâtel tax even spouses in inheritance matters?
Neuchâtel maintains taxation of inheritances between spouses and direct descendants, at preferential rates (3-5%). This particularity is explained by local political choices different from other French-speaking cantons. Geneva and Vaud, by contrast, fully exempt the surviving spouse.
What is the impact of moving to a favourable canton on inheritance?
An effective move to a fiscally advantageous canton (Schwyz, Zug, Obwald) can drastically reduce the inheritance tax burden on movable assets. The canton of the deceased's last domicile is competent to tax these assets. Note: the move must be genuine (centre of vital interests) and not fictitious.
How are real estate assets distributed across several cantons taxed?
Each canton taxes real estate situated on its territory, regardless of the deceased's domicile. Thus an estate can simultaneously be subject to several different cantonal tax regimes if the assets include property in multiple cantons. Only movable assets follow the canton of the last domicile.
