Cantonal Differences That Matter When Buying Property in Switzerland

Switzerland is often described as a single country with 26 different property markets. While federal law sets the broad framework, cantons (and sometimes municipalities) apply their own rules on taxes, fees, permits, and procedures. For an expat, these differences can affect whether you're allowed to buy at all, how much the purchase will cost, and how the property is taxed afterward. Here's what to look at canton by canton.

Lex Koller and foreign-buyer restrictions

The federal "Lex Koller" law restricts purchases of Swiss real estate by people who are not Swiss residents with the right nationality/permit status. Broadly, foreigners without a settlement permit (C permit) or without Swiss/EU-EFTA residence status face limits when buying, especially for holiday homes or investment property. However, the way these rules are applied — including quotas for holiday apartments, definitions of "tourist" regions, and the approval process — is administered at cantonal level. Some cantons (particularly popular alpine and lakeside tourist areas such as parts of Valais, Graubünden, and Ticino) actively manage limited quotas for non-resident foreign buyers of holiday homes, and these quotas can be exhausted in a given year. Other cantons apply Lex Koller more restrictively or have local rules layered on top. If you don't hold a C permit or aren't an EU/EFTA national living in Switzerland, always check the specific cantonal authority (often the cantonal Grundbuchamt or a designated Lex Koller office) before making an offer.

Transfer taxes and registration fees

When you buy property, most cantons levy a property transfer tax (Handänderungssteuer) and a fee for entry in the land register. Rates, who pays them (buyer, seller, or split), and even whether the tax exists at all vary considerably by canton. A handful of cantons charge little or nothing in transfer tax, while others apply a percentage of the purchase price that can be a meaningful added cost. Because these figures change and differ by canton and sometimes by municipality, don't rely on general figures you've seen online — ask the notary or the cantonal tax office handling your transaction for the current rate.

Notary systems differ by canton

Switzerland has no single national notary system. Some cantons (such as Zurich) use a public/state notary system, while others (such as Geneva and Vaud) have their own cantonal notary structures, and many German-speaking cantons use freelance notaries who are still bound by cantonal rules. This affects who drafts the purchase contract, how fees are calculated, and the language in which documents are prepared. In French-speaking cantons, expect the deed and negotiations to be conducted in French; in Italian-speaking Ticino, in Italian. Having a lawyer or advisor who works in the relevant cantonal system and language is genuinely useful, not just a nice-to-have.

Annual property and wealth taxes

Once you own a home, you'll typically face an imputed rental value (Eigenmietwert) added to your taxable income if you live in the property, plus wealth tax on its value, and possibly a separate cantonal property tax. The methodology for valuing the property, the applicable tax rates, and whether a municipal surcharge applies all vary by canton — and often by municipality within the canton. Two similar apartments in different cantons can have quite different annual tax burdens purely because of local tax rates and valuation practices.

Holiday-home caps and zoning rules

Separately from Lex Koller, Switzerland's Second Homes Act limits the proportion of secondary (holiday) residences allowed in many tourist municipalities, largely to curb "cold beds" and protect housing for full-time residents. Whether a given municipality has reached its cap, and what exceptions exist (for example, for primary residences or certain rental commitments), depends on very local zoning decisions. This is on top of cantonal-level Lex Koller quotas, so a holiday-home purchase in a popular resort can face two separate layers of restriction.

What this means practically

Before falling in love with a property, find out: whether your permit/residence status allows you to buy in that canton at all; what transfer tax and registration costs apply locally; which notary system and language you'll be dealing with; how the property will be taxed annually where it's located; and whether any secondary-home quota affects that specific municipality. The cantonal land registry office (Grundbuchamt/Registre foncier) and cantonal tax administration are usually the most reliable first points of contact, alongside a lawyer or notary experienced in that canton's practice.
