Lucerne Inheritance Tax — Nonresident Guide
How the Canton of Lucerne (Kanton Luzern) taxes nonresidents at death: what counts as Lucerne-situs property, when filings are triggered, how to coordinate across cantons and countries, documentation checklists, double-tax relief, and worked examples.
What Counts as Lucerne-Situs Property?
| Asset type | Lucerne nonresident treatment | Notes |
|---|---|---|
| Immovable property (real estate) located in Lucerne | Included in Lucerne taxable base | Primary trigger for a filing; valuation at death; debts allocable to the property may be creditable against value. |
| Tangible movables physically in Lucerne | Usually included | Vehicles, art, valuables kept in the canton; prove location with invoices, storage agreements, or inventory photos. |
| Business assets tied to a fixed facility in Lucerne | Potentially included | Functional connection to a Lucerne permanent establishment matters; allocation keys may apply. |
| Intangibles (bank deposits, portfolio shares, claims) | Generally follow domicile of decedent | Often not Lucerne-situs for nonresidents, subject to specific anti-avoidance or look-through rules. |
| Units in Lucerne real-estate funds holding LU property | Fact-specific | Look-through may apply if vehicle is transparent; confirm with the tax office. |
Filing Triggers for Nonresidents
- Ownership at death of Lucerne real estate or other LU-situs assets.
- Gifts causa mortis or death-proximate transfers of LU-situs assets (where applicable).
- Estate administered abroad with LU assets: a Lucerne filing can still be required.
- Heir located in Lucerne: may affect contact point but situs drives the base.
When in doubt, make a protective notification to the Lucerne tax authority and request instructions. See Forms & Deadlines.
Inter-Cantonal & Cross-Border Allocation
Switzerland avoids double taxation through inter-cantonal allocation principles. For cross-border estates, foreign inheritance/estate taxes may apply alongside Lucerne’s assessment on LU-situs assets. Coordinate timing, valuations (FMV at death), and deductions to keep positions consistent across jurisdictions.
Documentation Checklist
Evidence of situs
- Land register extract, purchase deed, latest municipal valuation.
- Location proof for movables (storage contracts, insurance schedules).
- Business facility lease or registration showing Lucerne presence.
Estate & heirs
- Death certificate, will, succession certificate (Erbbescheinigung).
- Executor/administrator appointment and contact details.
- Beneficiary list with relationships (for rate class/exemptions).
Valuation & debts
- Independent appraisal or valuation report at date of death.
- Mortgage statements and debts allocable to LU property.
- Rental statements (if income property) and expense ledgers.
Cross-border coordination
- Foreign inheritance/estate returns and assessments.
- Evidence of foreign tax paid for credit/relief claims.
- Translations of key documents where required.
Worked Examples
- UK-domiciled decedent with a Lucerne apartment. Only the Lucerne apartment (net of LU-allocable mortgage) is included in the Lucerne inheritance tax base. UK reporting covers the worldwide estate; seek relief to avoid double taxation on the LU asset.
- German resident owning shares and a LU art collection stored in Germany. Shares and movables outside Lucerne generally follow domicile and are outside LU-situs; no LU filing unless a LU-situs asset exists.
- Nonresident with a Lucerne fixed facility (workshop) holding machinery. Business assets functionally tied to the LU facility may be allocated to Lucerne; file and allocate value accordingly.

Double-Tax Relief & Credits
Where foreign and Lucerne taxes both apply to the same asset, relief mechanisms (inter-cantonal coordination and foreign tax credits under domestic rules or treaties, where available) can mitigate double taxation. Maintain synchronized valuation dates, currency conversions, and debt allocations.
Where to File & Deadlines
- Who files? Executor/administrator or beneficiaries as instructed by the Lucerne tax office.
- When? The tax office typically sets a due date; extensions are usually possible on request.
- Where? See addresses, portals, and downloadable forms on Forms & Deadlines.
Interest/penalties may apply for late filing or payment. Make early contact to secure extensions if valuations are pending.
Common Pitfalls
- Assuming foreign domicile eliminates Lucerne exposure despite owning LU real estate.
- Missing deductions for debts directly tied to LU property.
- Using foreign valuation dates or methods that don’t match Swiss practice.
- Failing to look-through certain vehicles that primarily hold LU real estate.
- Not coordinating with planning steps taken shortly before death.
