Questione giuridica chiave
Whether actual property maintenance costs and taxes had to be deducted when calculating supplementary benefits.
Decisione estratta
No. For supplementary benefits, building maintenance costs are only deductible as a flat-rate amount, and current taxes or earlier tax debts are not additional deductible expenses.
Motivazione estratta
The ELG exhaustively lists recognized expenses; Art. 16 ELV validly limits maintenance costs to a flat-rate deduction. Taxes are not part of the statutory expense catalogue and cannot be deducted as such. Earlier tax debts could only affect assets, but no assets were assessed.
