Switzerland Real Estate & Property Tax Guide 2026

Imputed Rental Value (Eigenmietwert)

• What it is: Owner-occupiers of residential property (houses, apartments) are deemed to receive rental income equal to the imputed rental value (Eigenmietwert / valeur locative) of their home. This deemed income represents the benefit of living rent-free in your own property. The imputed rental value is typically set at 60–80% of the actual market rent that would be charged for a comparable property, though the exact percentage varies by canton.
• Tax treatment: The Eigenmietwert is added to your other income (employment, investment) and taxed at your ordinary progressive income tax rate (federal and cantonal). It is a non-cash deemed income — you pay tax on it even though you do not receive actual cash rent.
• Controversy and reform: The Eigenmietwert is politically controversial. Opponents argue it is a tax on imputed income that no other country (except a few) levies. Multiple popular initiatives have attempted to abolish it, all rejected by Swiss voters (most recently in 2021). The deduction of mortgage interest against the Eigenmietwert partially compensates for the tax burden. A reform to reduce the Eigenmietwert to 60% of market rent is under discussion, but no changes are expected for 2026.

Mortgage Interest Deduction

• Fully deductible: Mortgage interest on loans used to acquire, construct, or renovate owner-occupied property is fully deductible from taxable income at both federal and cantonal levels. There is no cap on the deduction (unlike some countries such as the Netherlands). This means high-net-worth individuals with large mortgages can significantly reduce their income tax liability.
• Limitation: The deduction is limited to interest on debt used for the property. If the mortgage exceeds the property's market value (i.e., the loan is partially used for other purposes), the interest deduction is proportionally restricted. The tax authorities scrutinise mortgage refinancing where the funds are withdrawn for private consumption (e.g., buying a car) — the interest on such excess debt is not deductible against property income.
• Tax planning: Maintaining a mortgage (rather than paying off the property) can be tax-efficient because the interest deduction reduces income tax, and the cash used to pay off the mortgage could alternatively be invested in securities (which also generate investment income). However, the non-deductibility of wealth tax on the property (if the mortgage reduces net wealth) must also be considered.

Property Gains Tax (Grundstückgewinnsteuer)

• What it is: A cantonal tax on the capital gain realised upon the sale of real estate. The gain is calculated as the difference between the sale proceeds and the acquisition cost (plus cost of improvements, minus depreciation previously claimed). The tax applies to both owner-occupied and investment property, though owner-occupied property generally benefits from lower rates or exemptions for long holding periods.
• Progressive rate based on holding period: The tax rate depends on the length of ownership — the shorter the holding period, the higher the rate. For example, in Zurich: sale within 1 year: approximately 30–40% of the gain; after 5 years: 20–30%; after 10 years: 15–25%; after 20 years: 5–15%; after 30 years: 0–5%. The exact rates vary by canton — each canton publishes its own holding period rate table.
• Reinvestment relief (Ersatzbeschaffung): If the sale proceeds are reinvested in replacement property (principal residence) within a certain period (typically 1 year before to 2 years after the sale), the tax on the gain can be deferred. The deferred gain is deducted from the acquisition cost of the new property and becomes taxable when that new property is eventually sold without reinvestment. This relief is available for both owner-occupied and certain investment properties (e.g., rental property replaced with another rental property in some cantons).
• Exemptions: The sale of a principal residence after age 60 (or due to disability, nursing home admission, death) may be fully or partially exempt from property gains tax in some cantons. Gifts and inheritances of real estate are generally not subject to property gains tax — the gain carries over to the recipient's acquisition cost (tax-neutral rollover).

Real Estate Transfer Tax (Handänderungssteuer)

• What it is: A one-time tax on the transfer of ownership of real estate, levied at the cantonal (and sometimes municipal) level. The tax is typically payable by the buyer, though in some cantons it is split between buyer and seller. The rate is a percentage of the purchase price or the market value, whichever is higher.
• Rates by canton: Zurich: 1–3% (progressive); Zug: 0.5%; Geneva: 0.6% (CHF 700 minimum); Vaud: 1.1–1.4%; Bern: 1.0–1.5%; Basel-Stadt: 1.5–2.5%; Lucerne: 1.0%. The tax is applied on the full purchase price, with no exemption for the first tranche. For a property purchase of CHF 1,000,000, the transfer tax ranges from CHF 5,000 (Zug) to CHF 25,000 (Zurich at 2.5%).
• Exemptions: Transfers between spouses, direct descendants (parents to children, grandparents to grandchildren), and within certain family-owned businesses are generally exempt from transfer tax in most cantons. Transfers upon inheritance are also exempt. The exemption for direct descendants makes family property succession tax-efficient.

Annual Property Tax (Liegenschaftssteuer)

• Cantonal variation: Some cantons levy an annual property tax (Liegenschaftssteuer / impôt foncier) on the value of real estate. This is separate from wealth tax and income tax. The tax is calculated as a percentage of the property's tax value (Steuerwert).
• Cantons that levy property tax: Vaud (0.2–0.3% of tax value), Geneva (0.2%), Neuchâtel (~0.2%), Jura (~0.2%), Ticino (~0.1–0.3%), Fribourg (~0.1%). The property tax is not deductible for income tax purposes in most cantons.
• Cantons without annual property tax: Zurich, Zug, Bern, Basel-Stadt, Basel-Land, Lucerne, St. Gallen, Aargau, Schwyz, and most German-speaking cantons do not levy an annual property tax. This makes property ownership less costly in these cantons compared to French-speaking Swiss cantons that have the tax.

Taxation of Rental Income

• Fully taxable: Rental income from investment property is fully taxable at ordinary progressive rates (federal and cantonal). The rental income is reported as part of total income on the tax return. Deductible expenses include: mortgage interest, maintenance and repair costs, management fees, insurance premiums, and depreciation.
• Depreciation: Investment property can be depreciated for tax purposes. The depreciation rate depends on the type of construction (typically 1–2% for buildings, 10–20% for fixtures and fittings). Only the building value (not the land value) is depreciable. Depreciation reduces taxable rental income and can create a tax loss that offsets other income.
• Loss offset: If rental expenses exceed rental income (e.g., due to high depreciation or mortgage interest), the resulting loss can generally offset other income (employment, investment) in most cantons. However, the loss offset is limited in some cantons if the property generates sustained losses over multiple years — the tax authority may disallow excessive loss offsets.

Non-Resident Property Ownership

• Lex Koller (Koller-Erlass): Non-residents (foreign nationals residing outside Switzerland) are subject to the Lex Koller restrictions on acquiring real estate in Switzerland. The law applies primarily to residential property — non-residents may acquire only a holiday home (Zweitwohnung) in designated tourist areas and subject to a quota. The restrictions do not apply to commercial real estate. EU/EFTA nationals are exempt from Lex Koller if they have a Swiss residence permit (B or C permit).
• Taxation of non-residents: Non-residents are subject to Swiss tax on Swiss real estate only (not worldwide income/wealth). Rental income from Swiss property is taxed at source (Quellensteuer) at a flat rate in most cantons (typically 10–20% of gross rental income, depending on the canton). Property gains tax on sale applies under the same rules as for residents (progressive rate based on holding period). Wealth tax on Swiss real estate also applies for non-residents.
• Withholding tax on sale: Upon the sale of Swiss real estate by a non-resident, the canton will generally withhold a portion of the sale proceeds (typically 20% of the gain or 5% of the sale price) pending the final tax assessment. The withholding is refunded once the property gains tax is assessed and paid.

FAQs

What is the Eigenmietwert and why is it taxed?

The Eigenmietwert (imputed rental value) is a deemed income that owner-occupiers must declare — it represents the rental benefit of living in your own home. The rationale is that a homeowner receiving rental income would be taxed, so the imputed benefit of living rent-free should also be taxed. The Eigenmietwert is typically 60–80% of the market rent. Mortgage interest is deductible against this deemed income, reducing or eliminating the net tax impact for many homeowners.

Is there a capital gains tax on the sale of a principal residence?

Yes and no. Switzerland does not tax capital gains on movable property (shares, crypto) for private individuals — but real estate gains are taxed. When you sell your principal residence, you pay property gains tax (Grundstückgewinnsteuer) on the profit. However, if you have owned the property for a long time (20+ years), the effective rate may be very low (single digits). If you are 60+ or moving to a nursing home, the gain may be tax-free in some cantons. Reinvestment relief (Ersatzbeschaffung) allows deferral if you buy another principal residence within 1 year.

Can I deduct renovation costs?

Yes. Maintenance and renovation costs for owner-occupied property are deductible as they are incurred (not capitalised). Major renovations (e.g., new roof, new heating system, kitchen replacement) are typically deductible in the year they are paid. Value-enhancing improvements (e.g., adding a room, converting the attic) are not deductible — they increase the property's tax cost basis for future property gains tax calculation. The distinction between maintenance (deductible) and value-enhancing (capitalised) can be subtle and is frequently disputed with tax authorities.

What is the difference between Grundstückgewinnsteuer and Handänderungssteuer?

Property gains tax (Grundstückgewinnsteuer) is a tax on profit — you pay it when you sell a property and make a gain. Real estate transfer tax (Handänderungssteuer) is a tax on the transfer itself — you pay it when you buy a property, calculated on the purchase price (not the gain). Most cantons apply both: the buyer pays Handänderungssteuer (up to 3% of the price), and the seller pays Grundstückgewinnsteuer on the profit.

Do I pay wealth tax on my property?

Yes. Real estate is included in your taxable wealth for wealth tax (Vermögenssteuer) purposes. The value used for wealth tax is the tax value (Steuerwert), which is typically 60–80% of the market value. Mortgages are deductible, so the net wealth attributable to the property is the tax value minus the mortgage. See our Wealth Tax Guide → for more details.
