A taxpayer inquired whether they could claim the tax deduction for energy efficiency renovation works on their single-family home if, in addition to replacing windows, they enlarged an opening to increase natural light without improving efficiency. The Directorate General for Taxes (DGT) ruled that enlarging the opening does not entitle the taxpayer to the deduction, but the other works do qualify provided the energy efficiency improvement requirements are met.
Cuestión planteada Posibilidad de aplicarse la deducción por obras de rehabilitación energética en viviendas por las actuaciones realizadas.
La actuación de ampliar un hueco de ventana para ganar luz no genera derecho a la deducción por no tener incidencia en la eficiencia energética. No obstante, el contribuyente podrá aplicar la deducción de la disposición adicional 50ª de la LIRPF por las demás obras realizadas, siempre que se acredite la reducción del consumo de energía primaria no renovable en un 30% o la mejora de la calificación a clase 'A' o 'B'.
