On September 28, 2025, voters have decided to abolish the imputed rental value (Eigenmietwert), thereby changing the income tax system. The referendum proposal was difficult to understand. Only those who examined the issue in great detail realized that, in addition to abolishing the imputed rental value and creating a special cantonal tax on second homes, it also involved the abolition of tax deductions that have nothing to do with the imputed rental value. The reform of residential property taxation therefore raises new tax issues that will concern not only homeowners but also tenants.
