How the Canton of St. Gallen (Kanton St. Gallen) taxes nonresidents on St. Gallen-situs assets: who is taxed, what’s in scope, cross-border coordination, filing mechanics, documents, examples, and FAQs.

Service notice: Swiss inheritance tax services are delivered by Sesch TaxRep GmbH, Buchs SG (Switzerland).

At a Glance — Nonresident Exposure

Who is taxed?
Nonresident estates/beneficiaries are typically taxed in St. Gallen on SG-situs assets only, primarily immovable property (real estate) located in the canton.
What’s outside scope?
Most intangibles (e.g., bank accounts, portfolio shares) follow the decedent’s domicile and are generally not SG-situs for nonresidents, unless functionally tied to a St. Gallen permanent establishment.
Debt allocation
Deduct only debts allocable to SG-situs assets (e.g., a mortgage on SG real estate). Keep evidence.
Double taxation
Relief usually relies on inter-cantonal allocation and foreign credits. Align valuation dates and documentation across jurisdictions.

Action: Provide storage/insurance evidence; exclude UK-held intangibles from the SG base.

FR company with SG workshop (PE)

Scope: Assets functionally tied to the SG facility may be allocated to SG.

Action: Document nexus (leases, payroll, photos); provide an allocation methodology.

US domicile + SG apartment (no mortgage)

Scope: Apartment fully included; no debt deduction.

Action: Plan liquidity; consider instalment options with the tax office if needed.

Filing Mechanics (Nonresident Cases)

  • Who files: Executor/administrator or local representative; beneficiaries may be addressed directly for their share.
  • When to file: The tax office sets a due date by notice. Request extensions before the deadline if appraisals or foreign clearances are pending.
  • Where to file/pay: See Forms & Deadlines for the latest official links, addresses, and portals.
  • Computation model: SG-situs assets minus allocable debts and exemptions; rate class depends on relationship to decedent.
  • Payments: Interest may accrue after the payment due date on the assessment letter; instalments may be possible on request.

Documents & Evidence Checklist

  • Death certificate; will; succession certificate (Erbbescheinigung).
  • SG land register extract; date-of-death appraisal; photos and floor plan.
  • Mortgage statement as of date of death; bank proof of payoff/interest if applicable.
  • Inventory of SG-held movables (storage/insurance contracts).
  • Proof of beneficiary relationships (marriage/birth certificates; translations as needed).
  • Foreign estate/inheritance returns and proof of tax paid for credit claims.
