Key facts

• What: Inheritance and gift taxes managed at cantonal level
• Where: Canton Zurich (each Swiss canton has its own rules)
• Who: Zurich Cantonal Tax Administration
• Levels: Federal + cantonal + municipal system
• Structure: Progressive rates by degree of kinship (spouse, children, siblings, others)
• Competence: Cantonal, not federal laws

Switzerland does not have a federal inheritance tax. Unlike many foreign jurisdictions, inheritance and gift taxation is the exclusive competence of the 26 Swiss cantons, each with its own tax law and specific multipliers. This means that those who receive an inheritance in the Canton of Zurich are subject to Zurich's tax rules, which differ from those in Bern, Geneva, Valais or other cantons. Municipalities, within certain limits, also modify cantonal rates through local multipliers, creating further territorial variations.

How the cantonal inheritance tax is structured

The Swiss system is based on three key principles: the degree of kinship between the deceased and the heir, the amount of the share

Operational details

Rates and degrees of kinship

The degree of kinship determines the applicable rate. The Swiss system generally distinguishes four tax classes:

• Class I: Spouse, children, parents — minimum or no rates
• Class II: Siblings, grandchildren — intermediate rates
• Class III: Cousins and more distant relatives — high rates
• Class IV: Non-relatives — maximum rates

In the Canton of Zurich, as in every canton, the specific rates are established by cantonal legislation and vary depending on the hereditary income bracket. A close heir (child or spouse) may pay a minimal or no rate on small amounts, while higher rates apply to larger inheritances. A cousin faces significantly higher rates, even on small amounts.

# Spouse Exemptions

The surviving spouse generally enjoys preferential treatment in almost all Swiss cantons. In the Canton of Zurich, the spouse benefits from specific rules that guarantee patrimonial protection after the death of the partner. This preference reflects the desire to protect the surviving partner and ensure the couple's economic continuity. To verify the exact amount of the exemption and the specific conditions (e.g. legal separation or property regime), it is advisable to contact the Tax Office of the Canton of Zurich directly.

How to Declare an Inheritance in the Canton of Zurich

The declaration of succession is mandatory in the Canton of Zurich and must comply with specific deadlines to avoid penalties and surcharges. The procedure is articulated in several precise stages:

1. Notification to the canton

Within a term set by the canton (usually 30-90 days from death), one must inform the Canton Zurich Fiscal Office of the opening of the succession. This notification is usually made through a notary or directly by the heir or the executor of the will.

2. Filling in the declaration form

The heir must fill in the official cantonal form (available at the Canton Zurich Fiscal Office) indicating:

• The deceased's name and dates of birth and death

• A complete list of inherited assets (immovable property, bank accounts, securities, businesses, rights)

• The identity of all heirs with degrees of kinship

• The amounts of the inheritance shares for each heir

• Inherited debts and liabilities (mortgages, unpaid debts, funeral costs)

3. Payment of the tax

Calculated according to the Zurich tax rates, the payment must be made within the term set by the canton. Failure to pay or late payment result in interest on arrears and possible administrative penalties.

4. Conservation of documentation

It is advisable to keep a copy of the declaration, detailed calculations, and payment receipts for at least 7 years, the term of prescription for fiscal disputes in many Swiss cantons.
