How the DGT's position has evolved

Settled doctrine High confidence 12 rulings · 2014–2026

Current position

The aid granted through Royal Decree 477/2021 for self-consumption incentives, storage with renewable sources, and the implementation of thermal systems is not included in the IRPF (Personal Income Tax) taxable base. Although obtaining subsidies usually constitutes a capital gain, the 5th additional provision of Law 35/2006 establishes the exemption of these specific aids.

The DGT's position has moved from treating the deduction for investment in tangible fixed assets for renewable energies to focusing on the exemption of the subsidies from Royal Decree 477/2021. Following the suppression of deductions for energy improvements in the primary residence, the current criterion has consolidated around the non-taxation of self-consumption aid.
