Questione giuridica chiave
Whether the omitted dividend declaration caused forfeiture of the withholding tax refund claim under Art. 23 VStG.
Decisione estratta
Yes. The dividend was not properly declared before the ordinary assessment became final, so the refund claim was forfeited even though the omission was inadvertent.
Motivazione estratta
Art. 23 VStG requires correct self-declaration of relevant income. No intent to evade is needed; an accidental omission by the representative is attributed to the taxpayer.
