The Swiss inheritance tax system

Inheritance tax in Switzerland is not a federal matter, but a cantonal one. There is no single federal law, but 26 different cantonal disciplines. The Inner Appenzell canton, like every other Swiss canton, has complete autonomy in regulating the taxation of transfers of assets by succession and donation.

This decentralization produces concrete and tangible effects: those who inherit in Appenzell Interior are subject to the rules of the canton, which may differ significantly from those of Zurich, Bern, Geneva or other Swiss cantons. The consequence is that two heirs of the same degree of kinship, one resident in Inner Appenzell and one in Geneva, will be able to pay totally different tax amounts on the same inheritance.

Tax Rates by Degree of Kinship: The Incentive Structure

In the Swiss inheritance tax system, the degree of kinship is the first and fundamental criterion of tax differentiation. The canton of Appenzell Innerrhoden, like all Swiss cantons, classifies heirs according to a scale of family proximity to the deceased, and each class corresponds to a specific tax regime.

The Surviving Spouse: The spouse is the beneficiary of maximum tax protection. In almost all Swiss cantons, the surviving spouse pays no inheritance tax, or pays it at a minimal or zero rate. The underlying idea is that marriage constitutes a community of assets that tax policy should recognize and protect. A spouse who inherits the entire estate of a deceased partner does not suffer reduction of the inheritance due to inheritance taxes.

Children and Direct Descendants: They too enjoy significant exemptions or substantial reductions on moderate amounts of inherited assets. A child who inherits from a parent is taxed at significantly reduced rates, often with exemption up to a predetermined threshold. Amounts above the threshold apply rates that are still favorable compared to more distant degrees of kinship. This tax relief is based on the established principle that the vertical transmission of wealth within the immediate family should not be hindered by excessive levies.

Siblings: They apply intermediate tax rates, higher than those for spouses and children, but still reasonable and sustainable. They are considered heirs with sufficient proximity to receive preferential treatment.

Collateral Relatives: Cousins, aunts, uncles, great-aunts, and more distant relatives apply increasingly higher tax rates as the distance of kinship grows. The more distant the degree of relationship, the greater the tax burden.
