How the DGT's position has evolved
Current position
Gains from games of chance are capital gains. Losses are not deductible if they exceed the gains obtained in the same tax period or if they derive from games subject to special taxation. The justification of losses is carried out through the means of proof admitted under Law, the assessment of which corresponds to the Administration in accordance with the Civil Code and the Law of Civil Procedure.
The DGT's position remains constant regarding the classification of prizes as capital gains and the limitation of losses to the amount of gains obtained. The evolution focuses on precision regarding the exclusion of games with special taxation and the specification of the means of proof to justify losses.
