How the DGT's position has evolved
Current position
Compensatory interest for breach of contract or delay is classified as capital gains and not as income from movable capital. These must be included in the general tax base, following the doctrine of the Supreme Court. The temporal allocation is made in the tax period in which the judgment becomes final.
The DGT's position has moved from including interest in the savings tax base to including it in the general tax base. This change is observed in the transition from criteria such as V0129-21, which placed them in the savings base, towards the current doctrine set out in V0729-25. The evolution reflects alignment with the Supreme Court jurisprudence regarding the nature of these interests.
