How is rental income taxed in Switzerland?

Rental income is generally taxable in Switzerland as ordinary income. If you rent out property in Switzerland, you must declare the rental income on your Swiss tax return. However, you can usually deduct eligible expenses such as maintenance costs, mortgage interest and administration fees, meaning you are taxed on the net rental income. If you own rental property abroad, the income must still be declared, even if it is not directly taxed in Switzerland, as it may affect your overall tax rate through tax progression.
