How the DGT's position has evolved
Current position
Late payment interest for delays in payment is compensatory in nature to redress damages. It is not classified as income from movable capital, but as capital gains according to articles 25 and 33.1 of the Personal Income Tax Law (LIRPF). Following the doctrine of the Supreme Court, these interests must be included in the general tax base and not in the savings tax base.
The DGT has maintained the classification of late payment interest as capital gains of a compensatory nature since 2014. The relevant change occurs in the latest ruling (V1323-25), where the integration of these amounts is modified, moving from the savings tax base to the general tax base following the doctrine of the Supreme Court.
