Tax Inventory After Death in Switzerland: The 60-Day Deadline
Tax Inventory After Death in Switzerland: The 60-Day Deadline
Within two weeks of a resident's death, the local tax office (Steueramt) initiates one of the least-discussed but most time-critical processes in Swiss estate administration: the tax inventory (Steuerinventar). Heirs receive a detailed questionnaire demanding a comprehensive valuation of every asset the deceased owned — worldwide — calculated precisely to the date of death. They get 60 days to complete it.
What Triggers the Tax Inventory
The civil registry office (Zivilstandsamt) automatically notifies the local tax office when it registers a death. The tax office then sends a formal inventory request to the heirs or the designated executor (Willensvollstrecker), typically within 14 days.
This is not optional. Swiss cantonal tax law requires a complete accounting of the deceased's financial position at the moment of death, and heirs who held any asset jointly or have knowledge of the deceased's finances are legally obligated to cooperate.
What the Inventory Covers
The questionnaire demands valuations of:
- Bank accounts: All Swiss and foreign accounts, with balances as of the date of death
- Securities and investments: Stocks, bonds, funds — market value on the date of death
- Real estate: Swiss and foreign properties, at tax assessment value or market value
- Vehicles: Cars, boats, motorcycles
- Business interests: Shares in companies, partnerships, sole proprietorships
- Art, jewelry, and valuables: Estimated market value
- Life insurance policies: Surrender values and death benefits
- Pension assets: 2nd Pillar and 3a balances (though these follow separate tax treatment)
- Debts and liabilities: Mortgages, loans, credit card balances, unpaid taxes
Additionally, the heirs must submit the deceased's final tax return — covering income from January 1 of the year of death through the exact date of death. This is a partial-year return that must be filed alongside the inventory.
Safe Deposit Box Protocol
If the deceased held a safe deposit box (Banksafe / coffre-fort) at a Swiss bank, the opening procedure adds another layer of formality. The tax office may require that the box be opened in the presence of a notary or tax official, and the contents inventoried and documented. Banks typically won't allow heirs to access a safe deposit box until the Erbschein is issued, which means the inventory process and the Erbschein process run in parallel — the tax office may need the box contents for the inventory before the court has confirmed who the heirs are.
In practice, the tax office often accepts a preliminary inventory with a note that safe deposit box contents will be supplemented once access is granted.

The 60-Day Deadline
From the date the inventory questionnaire is received, heirs have 60 days to complete and return it. Missing this deadline has consequences:
- The tax office may issue an estimated assessment based on available information, which tends to overvalue assets
- Penalties for late filing
- Potential interest charges on any tax owed
If the estate is complex — multiple bank accounts, foreign assets, business interests — the 60-day window is tight. Start gathering documentation immediately.
Practical Challenges for Foreign Heirs
If you're managing an estate from abroad, assembling the inventory is especially difficult:
- Accessing the deceased's financial records may require a Swiss power of attorney or the Erbschein (which arrives after the inventory is due)
- Foreign asset valuations must be converted to CHF at the exchange rate on the date of death
- Coordinating with Swiss banks is complicated by the account freeze — banks may provide balance confirmations for tax purposes even while accounts are frozen, but you need to know which banks to contact
Inheritance Tax vs. Income Tax
The tax inventory serves two purposes:
- Final income tax: The deceased's income up to the date of death is taxed normally. Any outstanding tax liability becomes a debt of the estate.
- Inheritance tax: Cantons that levy inheritance tax (most do, except Schwyz and Obwalden) calculate it based on the total estate value determined through the inventory. The tax rate depends on the relationship between the deceased and each heir.
Surviving spouses are exempt from inheritance tax in most cantons. Direct descendants face low or zero rates in many cantons but significant rates in others (e.g., Vaud charges 1–3.5% on descendants above certain thresholds).
How to Manage It
- Start gathering documents the day the death is registered — don't wait for the inventory to arrive
- Contact all known banks and request balance confirmations as of the date of death
- Locate the previous year's tax return — it's the best map of the deceased's assets and accounts
- Engage a Swiss tax advisor if the estate includes business interests, foreign real estate, or complex investment structures
- Request an extension if needed — tax offices will sometimes grant additional time for complex estates, but you must ask in writing before the deadline
