How is Real Estate Gains Tax calculated in Zurich?

The calculation is based on the taxable real estate gain realised upon the sale of a property. It is determined as follows:

Sale proceeds – purchase price – value-enhancing investments – deductible expenses

= taxable real estate gain

The taxable real estate gain is multiplied by the applicable tax rate. Any surcharges or reductions are then applied to determine the final tax amount.

Permitted deductions for Real Estate Gains Tax in detail

Purchase price

When determining the taxable real estate gain, sellers may deduct the original purchase price of the property as well as all acquisition-related costs. These generally include:

Notary fees
Land register fees
Property transfer tax

Tip: If the last transfer of ownership took place more than 20 years ago, the market value of the property 20 years prior may be used instead of the original purchase price. A valuation can be requested from the tax authorities. This is often advantageous, as documentation relating to the original purchase may be incomplete or no longer available after such a long period of ownership.

Value-enhancing investments

This includes all investments that have increased the value of the property, such as renovation and modernisation works, conversions or extensions.

Important: Maintenance costs or purely value-preserving investments cannot be deducted.

Deductible expenses

These include the usual estate agent's commission as well as any advertising costs incurred in connection with the sale of the property.

Conversely, sellers who have owned their property for five years or more benefit from a tax reduction of up to 50%.
