The inquirer asks whether energy efficiency tax deductions can be applied to the installation of batteries for a photovoltaic system. The DGT rules that to claim these deductions, the requirements of Additional Provision 50 of the Personal Income Tax Law (LIRPF) must be met, which includes providing energy efficiency certificates issued both before and after the works.
Cuestión planteada Posibilidad de aplicar la deducción por obras de mejora de la eficiencia energética de viviendas prevista en la disposición adicional 50ª de la LIRPF.
Para aplicar las deducciones por obras de mejora de la eficiencia energética, el contribuyente debe acreditar el cumplimiento de los requisitos mediante el certificado de eficiencia energética expedido por técnico competente tras la realización de las obras. Asimismo, para acreditar el cumplimiento de los requisitos exigidos, serán válidos los certificados expedidos antes del inicio de las obras siempre que no haya transcurrido más de dos años entre su expedición y el inicio de las mismas. Si no se dispone de ambos documentos, no resultará de aplicación la deducción.
