Calculating income and wealth tax

Income tax

The Confederation, together with the cantons, communes and in some cases the parishes, levies income tax on all forms of earnings, whether occasional or regular, monetary or in kind. Taxable income is determined by subtracting the expenses and deductions permitted by law, as well as social deductions, from the taxpayer’s gross income.

Gross income includes a wide range of sources such as salaries, rental income, interest, dividends, and benefits in kind.

​General deductions

To calculate net income, taxpayers may deduct all expenses necessary to generate that income, whether from salaried or self‑employed activity, along with asset‑related costs. These may include travel and meal expenses, depreciation, administrative and maintenance costs, life‑insurance contributions, charitable donations, mortgage or other interest payments, health‑insurance premiums, and medical expenses.​‌

Social deductions

Certain flat‑rate deductions may be granted for dependent minor children in apprenticeship or education, or for individuals unable to work and supported by the taxpayer.

Once taxable income has been established, the tax office issues a tax assessment indicating the amount due. Income tax in Switzerland is progressive, meaning that higher incomes are taxed at proportionally higher rates.

Wealth tax

Unlike income tax, the Swiss cantons and municipalities are responsible for taxing wealth. Wealth includes a wide range of assets such as bank accounts, investments, securities, real estate, etc. Bank debts or loans from private individuals can be deducted from wealth. As with income tax, wealth tax is progressive and can vary significantly from canton to canton.

Unlike income tax, wealth tax is imposed solely by the cantons and municipalities. It applies to a broad range of assets, such as bank accounts, investments, securities, and real estate, from which debts, including bank loans or private borrowings, can be deducted. Wealth tax is also progressive and can vary significantly from one canton to another.

Examples of taxable assets include:​‌

• Cash
• Current accounts and other bank balances
• Securities such as savings bonds, bonds, and shares
• Units in investment funds​‌
• Mortgage loans
• Cryptocurrencies 
• Insurance premium deposits
• Real estate: Property, land, and buildings
• Precious metals such as gold and silver
• High-value assets such as cars, boats, horses, art collections and jewellery
  
  

Art objects, collector cars and luxury goods: are they taxable?​‌

The line between works of art and personal belongings can sometimes be unclear. Their tax treatment often depends on the object’s market value and how it is used in everyday life. High‑value artworks, or pieces insured beyond standard household coverage, are generally considered part of taxable wealth. Likewise, watches, jewellery and collector cars that are held primarily as investments rather than for personal use may also fall under wealth tax.

When declaring such items, it is advisable to remain transparent and to consider both their market value and their actual function in your daily life. For precise guidance on the taxation of collectors’ items, it is best to consult the tax authorities of the relevant canton.​‌

In the case of a second home

If you own a second home in a canton other than your canton of residence, it’s important to remember that the property will be taxed in the canton where it is located. This means you must declare the rental value of the second home, just as you would for your primary residence.

In Switzerland, the taxation of a second home follows the same principles as for a principal residence:

• Income tax on the property is collected by the canton in which the property is situated.

• The rental value must be included in your taxable income. This value does not reflect actual rental income but rather the theoretical rent the property could generate on the market, based on cantonal assessment rules and local price levels.

• Additionally, the tax value of the second home is added to your taxable wealth.
  
  

To help estimate your overall tax burden, many cantons provide online calculators for income and wealth tax. Here is a list by canton:​‌

Inheritance and Gift Taxes

Most Swiss cantons, and in some cases, municipalities, levy taxes on inheritances and gifts. All types of asset transfers may be subject to taxation: cash, valuables, insurance benefits, advancements on inheritance, and similar forms of wealth transfer.

The tax rate depends on two key factors: the value of the assets transferred and the degree of kinship between the donor and the beneficiary. The more distant the relationship, the higher the tax rate tends to be. Conversely, certain gifts, particularly those made to charitable or public‑benefit organisations, may benefit from reductions or even tax deductions.

In summary, Swiss taxation is based on a complex set of rules that require a careful analysis of income, assets, and eligible deductions. Calculation tools provided by cantonal tax authorities make it possible to obtain reliable estimates of taxable amounts and to better plan your financial situation.
