How the DGT's position has evolved

Refined position High confidence 33 rulings · 2014–2024

Current position

Legal interest derived from the nullity of clauses is taxed as capital gains. According to the latest doctrine, these interests are integrated into the general tax base. Regarding legal costs, they are considered capital gains, allowing the prevailing party to deduct the legal defense expenses incurred.

The DGT's position remains constant in classifying legal interest as capital gains. A relevant change is observed in the latest ruling (V0666-24), where the integration of these interests shifts from the savings tax base to the general tax base. The management of legal costs has also been specified to allow the deduction of defense expenses.

Turning points

  1. V0666-24

    Establishes that legal interest, due to its compensatory nature, is taxed as capital gains integrated into the general tax base, distinguishing it from the integration into the savings tax base applied previously.
