A taxpayer inquired about the requirements for claiming a tax deduction for the installation of solar panels on their property. The DGT ruled that it is essential to hold an energy efficiency certificate issued before the commencement of the works and another one upon completion to prove the required improvement.
Cuestión planteada Requisitos para la aplicación de la deducción por obras para la mejora de la eficiencia energética en viviendas prevista en la disposición adicional 50ª de la LIRPF.
Para aplicar las deducciones por obras de rehabilitación energética, es necesario acreditar la mejora mediante certificados de eficiencia energética expedidos por un técnico competente. Se requiere tanto el certificado previo al inicio de las obras (expedido en los dos años anteriores) como el certificado posterior a la realización de las mismas. Sin ambos documentos, no será posible aplicar la deducción.
