Home ownership and housing costs
Mortgage interest deductions
Mortgage interest on owner-occupied property can be deducted from income until further notice. This is changing: on 28 September 2025, the people and the cantons approved the change of system in the taxation of home ownership. On 1 April 2026, the Federal Council brought the reform into force as of 1 January 2029. From then on, the imputed rental value and, for the most part, the deduction of debt interest will no longer apply. The previous rules continue to apply for tax years up to and including 2028.
Retirement provision and saving

Contributions to pillar 3a are tax-deductible and directly reduce taxable income. In 2026, the maximum amount is CHF 7,258 with a pension fund; without a pension fund, it is 20% of earned income, up to a maximum of CHF 36,288.
Capital gains and capital losses on private assets
Capital gains from the sale of private assets are tax-free for direct federal tax. In return, capital losses on private assets are not deductible and cannot be offset against other income. However, the costs of managing movable private assets, such as custody fees, are deductible.
