Questione giuridica chiave
Whether Art. 21 lit. e LCP can be applied before determining the inter-cantonal apportionment of debts under Art. 40 LCP.
Decisione estratta
Art. 21 lit. e LCP applies only after identifying the deductible debts and, in inter-cantonal cases, after apportioning them under Art. 40 LCP.
Motivazione estratta
The provision concerns income calculation but presupposes assets and debts relevant to wealth tax. One must first determine which debts are deductible; only then can the corresponding deductible interest be calculated. Where assets are located in several cantons, that debt allocation must be carried out under Art. 40 LCP before the limitation in Art. 21 lit. e LCP is applied.
