How the DGT's position has evolved
Current position
The tax base varies depending on the nature of the tax: in Personal Income Tax (IRPF), subsidies for self-consumption and storage under RD 477/2021 are exempt from integration. In the Plastic Tax, the base is constituted by the kilograms of non-recycled plastic certified under the UNE-EN 15343:2008 standard. In Corporate Income Tax (IS), income from the sale of real estate is integrated when it is accounting-accrued through the transfer of control.
There is no single doctrinal evolution because the rulings address different tax matters (IRPF, Plastic Tax, IS, and IVA). In the case of self-consumption subsidies, the position remains constant by confirming the exemption under the fifth additional provision of the LIRPF. The remaining rulings present specific criteria for each tax without any relationship between them.
