Art. 199 Legge tributaria (StG) - Imposta supplementare a) Principio
SECONDA PARTE: TASSE STATALI - Sesto Capitolo: Organizzazione e Procedura - VI. Modifica di disposizioni e decisioni definitive
Art. 199 StG · Imposta supplementare a) Principio
1. Qualora emergano dati o prove che non erano a conoscenza dell'autorità fiscale, che dimostrino che un'accertamento non è stato compiuto correttamente o che un accertamento definitivo risulti incompleto, o se la mancata o incompleta accertamento è dovuta a un reato o delitto contro l'autorità fiscale, l'imposta non riscossa insieme agli interessi sarà richiesta come imposta complementare.
2. Se il contribuente ha indicato completamente e accuratamente nella sua dichiarazione fiscale gli elementi delle prestazioni e dei valori imponibili, e se le basi necessarie per la valutazione dei singoli elementi erano note all'autorità accertatrice, non può essere richiesta un'imposta complementare per una valutazione insufficiente.

Tax Reassessment of Deceased Shareholder Based on Unappealed Company Deemed Distributions
Mentioned in the reasoning (E. 3) as the legal basis for why the re-assessment procedure was permissible, which underpins the final orders (1 and 2).

Tax Assessment Upheld Due to Undeclared Foreign Income
The underlying legal basis for the tax reassessment (Nachsteuern) being upheld in the final orders (though primarily confirmed by the lack of challenge on its prerequisites in E. 6.1, it is fundamentally part of the context for the dismissal of the appeal against the prior decision on the merits).
B.2023.162.B.2023.1 · sg (Art. 199 Abs. 1 StG)

This provision, regarding the basis for imposing supplementary taxes (Nachsteuern), is mentioned in the reasoning but not explicitly cited in the operative section (Dispositive Orders 1-5) as the ground for dismissing the appeal. The dismissal of the appeal itself (Orders 2 and 3) is the final order, but the legal basis for the *substance* of the dismissal is found in the reasoning that the claim for supplementary tax was unfounded (E. 2.7.4), not in Art. 199 Abs. 1 StG itself being used in the operative part.
