What is wealth tax?

You may have heard it before, but Switzerland is still one of the few countries to have a wealth tax. Wealth tax is a tax that supplements income tax. Wealth tax is not levied by the Confederation.

In addition to its contribution in terms of tax revenue, wealth tax is also a control tax.

By monitoring changes in the taxpayer's assets over time, the tax authorities are able to check that income has been declared correctly.

Items subject to wealth tax

The taxpayer's wealth is broadly defined. It includes all movable and immovable property. The following in particular are subject to wealth tax:

  • the buildings
  • shares, bonds and transferable securities of any kind, capital outlays, contributions and limited partnerships representing an interest in a business, company or association
  • shares, bonds and transferable securities of any kind, capital outlays, contributions and limited partnerships representing an interest in a business, company or association
  • units in collective investments that own real estate directly, for the difference between the value of the total assets of the investment and the value of its directly owned real estate
  • mortgages and unsecured claims
  • the elements that make up commercial assets
  • life and old age insurance for their cash value
  • les bijoux et l’argenterie, lorsque leur valeur dépasse 2’000 CHF
  • livestock, both dead and alive

Items exempt from wealth tax

  • furniture, including artistic and scientific collections that can be considered as such
  • clothing
  • household utensils
  • books for the use of the taxpayer and his family
  • capital paid in as savings (LPP)

Determining gross and net assets

Wealth tax is levied on the taxpayer's total net wealth as at 31.12 of the year in question, after social security deductions. It is therefore important to make a proper assessment of this.

In general, assets must be valued at market value. [Art.14 al.1 LHID] Market value means the price that would be obtained in the event of a sale under normal conditions.

However, cantons may depart from this valuation method and use the return value. The yield value is obtained by dividing the yield for a given period by a capitalisation rate.

The yield value is mainly used for buildings used for agricultural purposes. On the other hand, property that is not used for agricultural purposes cannot be valued solely on the basis of yield.

Determination of gross assets

Moveable assets

The market value is decisive valuation at 31.12. of the year for which tax is due.

 Certificate from your bank as at 31.12.

Tax value Cryptocurrencies
 Every year, the Federal Tax Administration publishes the exchange rates for each virtual currency of a certain size, compiling data from several platforms. 

In the absence of a valuation price, the cryptocurrency in question must be declared at its initial purchase price converted into Swiss francs and not at the price on 31.12.

Listed securities
 This type of security is valued at its market value at 31.12.

Non-listed securities Switzerland
 Non-listed securities are valued according to the yield and intrinsic value of the company in question. In practice, the cantonal tax authorities refer to the valuation rules set out in CSI Circular No. 28. Special valuation rules apply to real estate companies.

The valuation of Swiss securities will be provided to you directly by the cantonal administration.

Foreign unlisted securities
 This type of security is treated in the same way as unlisted Swiss securities. The tax authorities must be provided with all the information they need to assess the company correctly, including balance sheets, profit and loss accounts, annexes and the purchase contract.

However, you can ask the tax authorities for a Ruling. 

Loans granted
 A certificate signed by the person paying the benefit is sufficient.

Business assets
 Are valued at their taxable value, which generally corresponds to the book value.

Life insurance subject to surrender
 Certificate from life insurance provider at 31.12.

Jewellery and silverware
 At market value, i.e. resale value under normal conditions

Real estate assets

The tax value corresponds to the purchase price on the contract.
Properties subject to usufruct are taxable with the usufructuary.

Property abroad
The purchase price of the property is decisive converted into francs using the tax rate for the year of acquisition. Property abroad is included only for the purpose of setting the tax rate.

Properties received as gifts/assignments
The tax value corresponds to the value retained by the tax authorities at the time of the event. 

Rental properties
A property containing more than two dwellings is considered to be a rental property. Its value will be determined by capitalising the rents received and/or the annual rental value. The capitalisation rate change every year.

Commercial and/or industrial property
This type of property is valued taking into account the current value of the land, buildings and ancillary facilities.

Farm buildings
Properties used for farming and forestry, including the part used as the owner's home, are valued at their yield value.  

It should be noted that the Federal Council has published the new guide to estimating agricultural yield value which came into force on 1 April 2018. Guide link

Determining net assets

Wealth tax is levied on the taxpayer's total net wealth, which is made up as follows:

+ gross assets (movable and immovable)
 - debts (mortgage, unsecured and private)
 - social deductions (depending on your situation)
 = Net taxable wealth

Gross assets

All your movable and immovable property (see above) valued in accordance with the above as at 31.12. of the year in question. 


Debts are deducted from gross assets.

They include :

  •  unsecured debts (unguaranteed debts)
  • mortgage
  • justified private debt
  • Extracts from negative accounts
  • Interest receipts


Debts can only be deducted from assets if they are actually owed by the taxpayer.

The guarantees may only be deducted in the event of the ascertained insolvency of the principal debtor. If the guarantee is by several people the calculation is made on a pro rata basis.

Geographical breakdown of debt

Persons who also own assets outside the canton of Geneva may deduct from their gross taxable assets only the portion proportional to the assets subject to tax in the canton.

Social deductions on wealth

The canton of Geneva provides for flat-rate social security deductions on all net assets declared by taxpayers liable for tax in the canton:

82,200 -> Single person without dependent children (e.g. single, widowed, separated or divorced)

164,400 -> Single person with dependent children or living in a joint household

41,100 -> for each additional child

 Deduction for the self-employed and partnerships :
 up to CHF 500,000 for half of the assets invested in the taxpayer's commercial, craft or industrial business; if a partner in an SNC: in proportion to his shareholding. 

Social security deductions on assets outside Switzerland

For taxpayers who, in addition to assets subject to tax in the canton, own assets outside the canton that are not subject to cantonal tax, the department allocates these deductions as follows proportionally assets subject to cantonal tax as a proportion of total assets.

Wealth tax calculation and scales

Wealth tax is calculated in brackets that accumulate in stages.

Barêmes impôt de base et supplémentaire sur la fortune

To do this, you need to work out which band you are in and then apply the rate for the final band to the difference between the top band and the bottom band.
