Kernrechtsfrage
Whether the IRS supplementary request met the treaty requirements for tax assistance under the DBA-USA, including a sufficiently plausible suspicion of tax fraud or similar conduct.
Extrahierter Entscheid
The request still satisfied the treaty requirements; the suspicion of tax fraud or similar conduct remained sufficiently substantiated.
Extrahierte Begründung
The new allegations about Y. Inc. did not change the core assessment. The request remained based on concrete indications previously accepted by the Court, and the additional corporate element did not dispel the suspicion.
