A taxpayer inquired whether they could claim the tax deduction for installing photovoltaic panels without a prior energy certificate. The DGT ruled that this is not possible, as regulations require proof of improvement based on a certificate issued before the commencement of the works.
Cuestión planteada Posibilidad de aplicarse la deducción por obras para la mejora de la eficiencia energética prevista en el apartado 1 de la disposición adicional 50ª de la LIRPF.
Para aplicar la deducción por reducción de la demanda de calefacción y refrigeración, es necesario acreditar la mejora mediante un certificado de eficiencia energética expedido después de las obras respecto al expedido antes del inicio de las mismas. Según la disposición adicional 50ª de la LIRPF, para acreditar el cumplimiento de los requisitos, son válidos los certificados expedidos antes del inicio de las obras siempre que no hayan transcurrido más de dos años desde su expedición. Al no disponer la consultante de un certificado previo dentro de ese plazo, no puede aplicar la deducción.
