Owning Swiss Property as a Non-Resident 2026: Limited Tax Liability and Eigenmietwert
Quick answer: Owning Swiss property as an Auslandschweizer triggers limited tax liability in the property canton at cantonal income tax rates. Eigenmietwert (deemed rental value) is taxed even when living abroad, if the property remains available for self-use. Cantonal property tax (Liegenschaftssteuer) continues. Sales from abroad are possible by notarised power of attorney.
Key takeaways
- Limited tax liability in property canton.
- Eigenmietwert applies abroad too.
- Cantonal property tax continues.
- Sale from abroad via PoA.
- Tax representative recommended.
Owning Swiss property as Auslandschweizer: rights and obligations
Swiss citizens and EU/EFTA residents can keep, buy or inherit Swiss property freely after emigration. Non-EU foreign residents are subject to the Lex Koller (Bundesgesetz über den Erwerb von Grundstücken durch Personen im Ausland) — limiting non-resident foreign acquisitions to a quota system, primarily for tourist regions (Engadin, Wallis, Tessin) and only for second-home purposes. As an Auslandschweizer, you are NOT subject to Lex Koller because you remain Swiss; emigration does not strip your citizenship.
Owning Swiss property as a non-resident triggers limited Swiss tax liability on Swiss-situs assets. The cantonal tax office sends a non-resident tax return (beschränkte Steuerpflicht) annually, covering: rental income or imputed rental value (Eigenmietwert), wealth tax on the property’s tax value, and any future capital gain at sale (Grundstückgewinnsteuer).
Eigenmietwert: the surprise tax for non-resident owners
Switzerland is one of the few countries that taxes the imputed rental value of owner-occupied property — even when the owner lives abroad. If you keep your Swiss home as a vacation property or vacant pied-à-terre, the cantonal tax office assesses the Eigenmietwert: typically 60-70% of the market rent the property could fetch.
The Eigenmietwert is added to your Swiss-source taxable income. Even though you live abroad, this triggers cantonal income tax (rates 0.5-7% effective for non-residents on Swiss-source income only). In return, you can deduct mortgage interest, maintenance costs, and insurance — partly offsetting the imputed income.
| Property scenario | Tax treatment for non-resident |
|---|---|
| Vacant or used as own holiday home | Eigenmietwert added to income; deductions allowed |
| Rented out long-term | Actual rental income taxed; deductions allowed |
| Rented out short-term (Airbnb) | Rental income + cantonal tourist tax; commercial classification possible |
| Used by family member rent-free | Eigenmietwert applies (imputed rent) |
The 2026 Eigenmietwert reform — what changes
After decades of debate, Swiss voters approved the abolition of the Eigenmietwert in a 2024 referendum, with implementation phasing in from 2026-2028. The reform replaces the imputed rental tax for principal residences only — second homes and rental properties are unaffected. For non-resident Auslandschweizer keeping Swiss property, the reform’s impact is limited because most fall into the second-home category.
From 2027 onwards, mortgage interest deduction for principal residences is also eliminated in parallel. Non-residents are unaffected, since their Swiss property is not their principal residence by definition. The cantonal authorities are still finalising guidance for transitional cases (e.g. Auslandschweizer who plan to return) — verify with your last canton’s Steueramt before relying on transitional rules.
Wealth tax on Swiss property as non-resident
The cantonal wealth tax (Vermögenssteuer) applies to Swiss-situs property regardless of residence. The taxable value (Steuerwert / valeur fiscale) is determined cantonally — typically 60-90% of market value. Wealth tax rates range 0.13% (Nidwalden) to ~1.0% (Geneva, Vaud) on the net property value (after deduction of mortgage debt).
Example: Geneva apartment valued at CHF 1’500’000 with CHF 800’000 mortgage. Wealth tax base = CHF 700’000. Wealth tax at ~0.45% = CHF 3’150/year (cantonal + communal combined). Plus Eigenmietwert income tax. Plus property tax (Liegenschaftssteuer) where levied (CHF 0.3-3 per mille of property value, varies by canton).
Renting out vs. keeping vacant
| Decision | Tax outcome | Practical considerations |
|---|---|---|
| Rent out long-term | Real rental taxed; full deductions; rental income often beats imputed | Need property manager (Liegenschaftsverwaltung), 5-8% of gross rent |
| Rent out short-term (Airbnb) | Higher gross income; tourist tax; cantonal limits in some places | Active management; some cantons (Geneva, Zurich-City) restrict |
| Keep as second home (own use) | Eigenmietwert taxed | Maintenance burden; insurance updates needed |
| Sell before/after move | Grundstückgewinnsteuer applies (degressive) | See property sale guide |
Mortgage and insurance considerations
Most Swiss banks allow Auslandschweizer to retain existing mortgages — though loan-to-value drops from 80% to 50-65%, requiring partial amortisation within 12-24 months. Cantonal banks are typically the most accommodating for property in their canton. Refinancing as a non-resident is harder: rates often 0.20-0.50% higher.
Property insurance: cantonal building insurance (Gebäudeversicherung) is mandatory in most cantons (only Geneva, Ticino, Uri, Schwyz, Wallis, Appenzell Innerrhoden have private competition). Premiums are unaffected by your residency. Liability and contents insurance should be reviewed — many policies require disclosure of non-occupied periods over 30-60 days, and may restrict water-damage coverage in unheated winter periods.
Inheritance and succession planning
Swiss real estate is governed by Swiss inheritance law for the property itself, regardless of the owner’s residence. The 2015 EU Succession Regulation (Brussels IV) doesn’t apply because Switzerland is not in the EU — but bilateral conventions (with USA, UK, Germany, Austria, etc.) and Swiss IPRG (Internationales Privatrecht) determine which law applies to the succession.
Cantonal inheritance and gift tax (Erbschafts- und Schenkungssteuer) applies to Swiss real estate regardless of where the heirs live or where the deceased was resident. Spouses and direct descendants are exempt in most cantons; collateral relatives (siblings, nephews) face 5-30% rates; non-relatives 20-50%. Plan with a Swiss notary if you intend to leave Swiss property to non-Swiss heirs.
Common mistakes by non-resident Swiss property owners
| Mistake | Consequence | Fix |
|---|---|---|
| Assuming Eigenmietwert disappears when you live abroad | Surprise cantonal tax bill | Plan for the imputed income; consider letting |
| Failing to file annual non-resident return | Estimated assessment + late-filing fines | Engage a Swiss tax adviser in your last canton |
| Losing mortgage at refinancing because of LTV cut | Forced sale or external refinancing | Negotiate amortisation plan with bank pre-move |
| Forgetting building insurance update | Coverage void during empty winter periods | Notify insurer; arrange winter heating monitoring |
| No succession planning for non-Swiss heirs | High inheritance tax + complex notary procedure | Visit Swiss notary; consider cantonal optimisation |

Will I still pay tax on my Swiss apartment if I move abroad?
Yes. Swiss real estate triggers limited Swiss tax liability regardless of your residence. You owe cantonal wealth tax on the property’s tax value (less mortgage), and either Eigenmietwert (imputed rental income) if you keep the home empty or for own use, or actual rental income tax if you let it. Most cantons require an annual non-resident tax return.
Does the 2026 Eigenmietwert reform help me as Auslandschweizer?
Limited impact. The reform abolishes the Eigenmietwert for primary residences only (phased 2026-2028). Second homes and rental properties — which describes most non-resident-owned Swiss property — remain subject to imputed rental tax. Mortgage interest deduction is also being eliminated in parallel for primary residences from 2027.
Can I keep my Swiss mortgage after emigrating?
Usually yes, with bank approval. Loan-to-value typically drops from 80% to 50-65% for non-residents — you may need to amortise the difference within 12-24 months. Cantonal banks are usually the most accommodating for property in their canton. Refinancing rates run 0.20-0.50% higher than for residents.
What inheritance tax applies to Swiss property left to foreign heirs?
Cantonal inheritance tax applies based on the property’s location, regardless of where the heirs or deceased lived. Spouses and direct descendants (children, grandchildren) are exempt in most cantons. Siblings, nephews, friends face 5-30% rates depending on canton. Non-relatives 20-50%. Plan succession with a Swiss notary, especially for high-value property in tax-heavy cantons like Geneva or Vaud.
