Key facts

What: Cantonal tax on inheritances and gifts
Where: Canton of Appenzell Ausserrhoden (system valid for all Swiss cantons)
Who: Heirs and beneficiaries of gifts
Regulation: Cantonal tax law (not federal)
Structure: Rates vary by degree of kinship

In Switzerland, inheritance and gift tax is not regulated at the federal level but remains the exclusive competence of each canton. The Canton of Appenzell Ausserrhoden, like all Swiss cantons, applies its own taxation system with specific rates and exemptions defined by the cantonal tax law. According to the general principle of Swiss taxation, the three levels of taxation (federal, cantonal, communal) operate autonomously: while the FTA administers the federal direct tax and VAT at the national level, the cantonal administration of Appenzell Ausserrhoden defines its own taxes on inheritances and gifts, and the communes apply additional multipliers.

In the cantonal taxation structure, the surviving spouse and direct descendants usually benefit from full exemptions or significantly reduced rates. Collateral relatives (brothers, cousins) face intermediate rates, while strangers are subject to the highest rates. This progressivity reflects the principle of tax capacity and family solidarity incorporated into the Swiss tax system.

Operational details

Exemptions and rates: the structure by degree of kinship

In the Swiss inheritance tax system, the surviving spouse is usually fully exempt from cantonal inheritance tax. The same benefit extends to children and direct descendants in a straight line, who also enjoy total exemptions or minimum rates, often close to zero percent. This structure reflects the established principle that transfers within the nuclear family should not be penalized fiscally, favoring patrimonial continuity between close generations.

Second-degree collateral relatives (brothers and sisters of the deceased) face intermediate rates, generally ranging between 5% and 20% depending on the canton. More distant relatives (cousins, uncles, second-degree nephews) are subject to further increased rates. Finally, non-relatives and unrelated heirs are subject to the maximum rates, which in some cantons can reach 30-40% or higher.

As for donations, the structure is analogous: the spouse and direct descendants often enjoy exemptions or significant reductions, while more distant relatives and non-relatives pay higher rates. In some cantons, the law also provides exemption thresholds: donations below a certain annual amount may be totally exempt from tax, regardless of the degree of kinship. This rule encourages modest transfers without tax burden.

Step-by-step guide: what to do in case of inheritance or donation

If you are a resident of the Canton of Appenzell Ausserrhoden and receive an inheritance or make a donation, follow this procedure:

Step 1: Gather the essential documentation. In case of inheritance, you will need the death certificate of the deceased, a detailed inventory of the assets (real estate, bank accounts, securities, businesses), property documents, and the last tax return of the deceased. For donations, prepare the documentation of the transaction, the estimated value of the donated assets, and any relevant notarial deed.

Step 2: Verify your degree of kinship and applicable exemptions. Determine your position relative to the deceased (spouse, child, sibling, distant relative, stranger). If you are a spouse or direct descendant, you are likely to benefit from full exemption from cantonal tax. For other degrees of kinship, identify the corresponding cantonal rate.

Step 3: Submit the declaration within the set deadline. Contact the cantonal tax office of Appenzell Ausserrhoden or the municipality of residence of the deceased and submit the inheritance declaration within the prescribed deadline (usually 3-6 months from the death). For donations, submit the declaration within the deadline set by cantonal law (generally 30-90 days). Use the official forms provided by the cantonal administration.

Step 4: Calculate the tax burden. Multiply the taxable amount (inheritance or donation net of exemptions) by the cantonal rate applicable to your degree of kinship. If relevant, apply the municipal multiplier. The result is the cantonal tax due.
