Swiss Property Gains Tax: Deductions & Holding Discounts

What is Grundstücksgewinnsteuer?

If you sell a property in Switzerland at a profit, you are subject to the Grundstücksgewinnsteuer (property capital gains tax). This tax is levied solely by the cantons and municipalities, and the rate depends on the size of your profit and how long you owned the property.

Swiss tax policy heavily penalizes short-term real estate flipping and rewards long-term property ownership.

Holding Duration Modifiers

• Speculation Surcharges (Short Ownership): If you sell a property after owning it for less than 1 or 2 years, cantons apply a penalty surcharge of up to 25% to 50% on top of the base tax rate.
• Holding Discounts (Long Ownership): For each year of ownership beyond 3-5 years, you receive a discount. For holdings exceeding 20 years, the tax discount can reach 50% to 70% depending on the canton.
