Owning a home is only one chapter of the story. Sooner or later the opposite question arises: how to part with the property. There are three routes — to sell it, give it away, or pass it on — and each comes with its own rules and, above all, its own tax logic. The paradox is that the size of the tax depends less on the price of the property than on how and to whom it changes hands and how long it was held. Let us look at these three scenarios as Swiss law sees them, and where the largest costs and miscalculations hide.

Selling through an agent and liability for defects

If you entrust the sale to an estate agent and they find a buyer, a commission of 2–3% of the sale price is customary. If you find the buyer yourself, you usually still owe the engaged agent a fee agreed in the contract, often around 0.5% of the price. So before signing with an intermediary, it is worth reading carefully exactly when and for what their right to payment arises.

The seller's liability deserves separate attention. By law you must inform the buyer of any defects in the house or apartment. In practice, sale contracts often contain a clause excluding warranty for hidden defects, yet such an exclusion does not apply where defects were deliberately concealed. If the buyer can prove intentional concealment, the seller risks being liable for damages. In other words, the wording of the contract reallocates risk, but it does not release anyone from the consequences of bad faith.

Property gains tax — the main cost when selling

Anyone who sells a house, apartment or plot of land at a profit pays property gains tax (Grundstückgewinnsteuer). This is not a federal tax but a cantonal and communal one: the Confederation does not levy it, but the tax harmonisation act obliges the cantons to tax such a gain. What is taxed is the difference between the sale price and the so-called investment costs — the original purchase price plus value-enhancing investments (conversions, renovations) and incidental costs: agent's commission, notary and land-registry fees, property transfer tax (Handänderungssteuer) and the cost of terminating a mortgage early. All of this reduces the taxable gain, which is why receipts are worth keeping for years.

The key feature is that the tax is degressive. The shorter the period of ownership, the higher the tax; the longer it is, the more noticeable the reduction. A short holding period attracts a surcharge, while the maximum relief is reached only after a long period — in Zurich after twenty years, in Bern after thirty-five. Depending on the canton, the size of the gain and the holding period, rates range from roughly 5 to 50%. The logic is plain: the system deliberately penalises a quick resale and rewards patient owners. The buyer, in turn, should ensure payment of this tax is secured in the contract, because in many cantons the seller's debt can be recovered from the new owner or through a lien on the property.

Deferral: when selling does not mean paying at once

Property gains tax can, in some cases, be deferred. The best-known case is replacement acquisition (Ersatzbeschaffung): if you sell a home you lived in yourself and, within a reasonable period — usually up to two years — buy or build a new owner-occupied home in Switzerland, the tax is not levied immediately. The deferral applies only to the portion of the gain that is reinvested; if the new home is cheaper than the one sold, the tax on the difference falls due at once. Deferral also applies when the property passes by inheritance, as an advance on inheritance, by gift, or between spouses.

Here it is important not to confuse deferral with exemption. The deferred tax does not disappear: on a subsequent sale to a third party it must be paid, with the gain calculated from the original purchase price rather than the value at which the property came to you. At the same time, the previous owner's period of ownership is credited, which may later lower the rate.

Gifting and inheritance — a different tax logic

When property is not sold but given away or left as an inheritance, an entirely different tax comes into play — the inheritance and gift tax (Erbschafts- und Schenkungssteuer). It, too, is cantonal; there is no such tax at federal level. Here the decisive factor is not the holding period but the degree of kinship between giver and recipient. Spouses and registered partners are exempt in every canton; direct descendants are exempt almost everywhere and are taxed only in a few cantons — notably Vaud, Neuchâtel and Appenzell Innerrhoden — as a rule at low rates with allowances. For distant relatives and unrelated persons, by contrast, rates can reach around 40%, and most cantons treat cohabiting partners as strangers. Two cantons — Schwyz and Obwalden — levy neither inheritance nor gift tax.

For real estate, one more rule applies: the gift or inheritance tax is levied not at the donor's place of residence but in the canton where the property is located. Moreover, gifting a property to relatives usually defers the property gains tax — the recipient inherits the property's tax history. The 2025–2026 context confirms this system's stability: a federal initiative for a nationwide inheritance and gift tax of 50% on amounts above 50 million francs was rejected by voters on 30 November 2025 by a wide margin. So the status quo holds at federal level — and with it the cantonal diversity of rules.

Arranging your estate during your lifetime

It is sensible to decide during your lifetime what is to happen to your assets — and to your property in particular — after your death. Swiss law offers several instruments for this: a will, an inheritance contract, an advance on inheritance, and gifts. Since the inheritance-law reform that took effect at the start of 2023, the freely disposable portion has grown, because the compulsory shares were reduced — leaving more room for your own decisions. This matters especially for real estate: indivisible and emotionally charged, so planning ahead helps avoid a forced sale and disputes among heirs.

The cross-border dimension deserves separate attention. The rules described here concern property located in Switzerland; for real estate abroad — in Ukraine, for instance — other rules apply, along with double-taxation agreements. If assets are spread across countries, the general guidance here is no substitute for professional advice.

What decides is not the price but the manner of transfer

Putting the three scenarios together, a common pattern emerges: the final tax weight is determined not by the property's price tag but by three other variables — kinship, holding period and canton. A sale triggers property gains tax with its degressive scale; a gift or inheritance leads to a different tax tied to family ties; and Swiss tax federalism means that the answer in Zurich and in Vaud may differ.

Hence the practical pointers. Keep documents on value-enhancing investments — they will reduce the tax on sale. Make sure payment of the gains tax is secured in the contract. For gifts and inheritance, check the rules of the canton where the property lies, not only your own. And plan the transfer of assets early. This article offers an analytical overview, not tax or legal advice: the binding answer in a specific case comes from the cantonal tax office, a notary or a qualified specialist. The diversity of cantonal rules is not a flaw but a deliberate feature of the system — which is precisely why every decision is worth checking against the place where it is made.
