WAK-S has defined key points for the system change in the taxation of residential property

As already stated in the text of the Commission initiative (17.400), second homes are to be excluded from the change of system. For the main residence the Commission envisages the following: Property maintenance costs should no longer be deductible in future. At the federal level, neither energy-saving and environmental deductions nor deductions for work related to the preservation of historical monuments will be permitted, but it will be up to the cantons to decide whether or not to maintain the possibility of such deductions in their tax legislation. The Commission wants to abolish the deduction of interest on owner-occupied housing. Only debt interest deductions amounting to 80 or 100 percent of the income from other assets (e.g. rental income, income from shares or securities) will be retained; the Commission is having two variants drawn up. Finally, in line with the constitutional mandate of the promotion of home ownership, the Commission would also like to include a deduction for first-time buyers in the preliminary draft; the aim remains to make the draft as budget-neutral as possible. The Commission will probably deal with the preliminary draft prepared by then in the first quarter of 2019.
