Swiss property tax (impôt foncier / Liegenschaftssteuer or Grundstücksteuer) is a cantonal or municipal annual tax levied on the official fiscal value (valeur officielle / amtlicher Wert) of real property located in Switzerland, regardless of the property's actual yield. It is separate from and additive to the wealth tax on the net value of the property. Several cantons — including Zug, Schwyz and Appenzell Innerrhoden — do not levy a separate property tax; others like Vaud apply a cantonal rate of approximately 0.15% of the official fiscal value, supplemented by variable municipal rates.

The official fiscal value used as the property tax base is typically below market value — in many cantons, fiscal values are updated infrequently and may reflect assessments from 10–20 years ago, significantly understating current market values. This creates an effective attenuation of the actual tax burden: a property market value of CHF 5 million may have an official fiscal value of CHF 3.2 million, reducing the effective tax base by 36%. At the time of a property transaction (sale), the fiscal value is typically reassessed, bringing it closer to market value.

The property tax is distinct from the Swiss real property gains tax (impôt sur les gains immobiliers / Grundstückgewinnsteuer), which is a cantonal tax on capital gains realised on the sale of Swiss real property. The gains tax rate decreases with the length of ownership (typically 5–10% after 20 years in most cantons) — creating a tax incentive for long-term real estate holding in Switzerland that is absent in France (where the notional PFU or progressive rate applies to all capital gains above the annual allowance).
