Refusal of the deduction right: "knew or ought to have known"
The central basis of the reassessment, rooted in the Kittel and Mahagében rulings of the European Court of Justice.
- The taxable person who "knew or ought to have known" that its acquisition implicated it in a VAT fraud operation is denied the deduction right (CJEU, 6 July 2006, Kittel, case C-439/04)
- The burden of proof lies with the tax authority: it must establish, from objective elements, your actual or presumed knowledge of the fraud (CJEU, 21 June 2012, Mahagében and Dávid, cases C-80/11 and C-142/11)
- The Court forbids the authority from demanding that the buyer verify his suppliers' fiscal standing as a general matter; heightened verification is required only in the presence of irregularity flags
- The French State Council has adopted this framework: each transaction is contested item by item, flag by flag, and doubt favours the taxpayer
