The questions every seller asks
What is the capital gains tax on property in Geneva?
The tax on real estate profits and gains is the Geneva cantonal tax levied on the gain made when a property is sold. The taxable gain is the difference between the disposal value (sale price less selling costs) and the acquisition value (purchase price, purchase costs and value-adding works). The rate depends solely on how long you have owned the property: from 50% under two years, it falls step by step to 2% beyond twenty-five years.
What is rollover relief, and who can benefit from it?
Rollover relief defers the tax when you sell your main residence and reinvest the proceeds in a new main residence in Switzerland. It applies only to the home you genuinely occupy — never a second home or an investment property. Administrative practice generally allows around five years between the sale and the repurchase.
Does rollover relief cancel the tax?
No — it defers it. Taxation is postponed until the new home is resold without a further rollover. And if you buy for less than you sold, the relief is only partial: the portion of the gain not reinvested is taxed immediately. This belongs in your financing plan before the sale, not after.
How is the length of ownership calculated?
From notarial deed to notarial deed: from the date of purchase to the date of sale. One important exception: if you received the property through inheritance or gift, taxation was deferred — and the previous owner's period of ownership carries over to you. A long-held family property therefore often reaches the lowest brackets of the scale.
Which documents reduce the taxable gain?
Value-adding works evidenced by invoices (extensions, major renovation, conservatory, lasting improvements), the purchase costs of the time (duties, notary), the brokerage fee and the costs of the sale. Routine maintenance is not deductible — it belongs to income tax. Keep every invoice: at your bracket's rate, each documented franc reduces the taxable gain by as much.
Who pays the tax, and when?
The seller, on the basis of a specific declaration filed after the sale. In practice the notary frequently withholds the estimated amount at signature: the cantonal authority holds a legal charge over the property sold to secure this claim, and withholding protects buyer and seller alike. Your broker and the notary coordinate this before signature.
