What changes for owners
Self-occupied properties (main and second residences) will no longer be taxable in the future, which significantly relieves the income.
In return, however, many of the previous tax deductions are omitted - in particular: debt interest on mortgages, maintenance, renovation or refurbishment costs as well as expenses for energy/environmental protection measures can no longer be deducted from income at the federal level.
For people who have just purchased a house or an apartment, there is a transitional rule: In the first ten years, a reduced debt interest deduction (similar to the past) can be claimed - but after that this deduction would no longer be possible.
For second homes or holiday properties, it is planned that the cantons can introduce a new tax - a cantonal property tax - in order to compensate for tax losses.
Time frame for the reform
The decision concerns all self-occupied properties.
As a rule, an implementation is expected by 01.01.2028 at the earliest - until then, the previous system will continue to apply.
