The right to deduct input VAT is denied not only if the taxable person himself commits an evasion, but also if he is aware that he participated with his acquisition in a tax evasion. In the latter case the refusal of the input tax deduction is a consequence of the failure to comply with the responsibilities in suspect cases. The taxable person who knew or should have known that he or she was participating in a fraudulent transaction assists the perpetrators of that fraud and becomes an accomplice thereto. The European Court of Justice (ECJ) confirms its previous case law on this issue. The ECJ case reference is C‑108/20 Finanzamt Wilmersdorf order of 14 April 2021.
