Questão jurídica principal
Whether the photovoltaic installation costs on a recently built house are deductible as maintenance/energy-saving expenses under direct federal tax law
Decisão extraída
No. The installation was part of a new-build-related value increase, not a deductible maintenance measure on existing property.
Fundamentação extraída
Deductible energy-saving investments apply only to existing buildings and to measures replacing outdated components or first installed in energetically poor buildings. Here, neither condition was shown; the installation followed the introduction of the feed-in tariff and resulted in full value increase rather than partly value-preserving maintenance.
