“54. As the court has already observed, preventing tax evasion, avoidance and abuse is an objective recognised and encouraged by the Sixth Directive (see Gemeente Leusden v Staatssecretaris van Financien (Cases C-487/01 and C-7/02),[2004] ECR I-5337 , paragraph 76). Community law cannot be relied on for abusive or fraudulent ends (see, inter alia, Kefalas v Greece and OAE (Case C-367/96 )[1998] ECR I-2843 , paragraph 20; Diamantis v Greece (Case C-373/97 )[2000] ECR I-1705 , paragraph 33; and I/S Fini H v Skatteministeriet (Case C-32/03 ),[2005] ECR I-1599 , paragraph 32). 55. Where the tax authorities find that the right to deduct has been exercised fraudulently, they are permitted to claim repayment of the deducted sums retroactively (see, inter alia, Rompelman v Minister van Financiën (Case 268/83) [1985] ECR 655 , paragraph 24; Intercommunale voor Zeewaterontzilting (in liquidation) v Belgium (Case C-110/94 ),[1996] ECR I-857 , paragraph 24; and Gabalfrisa (paragraph 46)). It is a matter for the national court to refuse to allow the right to deduct where it is established, on the basis of objective evidence, that that right is being relied on for fraudulent ends (see Fini H (paragraph 34)). 56. In the same way, a taxable person who knew or should have known that, by his purchase, he was taking part in a transaction connected with fraudulent evasion of VAT must, for the purposes of the Sixth Directive, be regarded as a participant in that fraud, irrespective of whether or not he profited by the resale of the goods. 57. That is because in such a situation the taxable person aids the perpetrators of the fraud and becomes their accomplice. 58. In addition, such an interpretation, by making it more difficult to carry out fraudulent transactions, is apt to prevent them. 59. Therefore, it is for the referring court to refuse entitlement to the right to deduct where it is ascertained, having regard to objective factors, that the taxable person knew or should have known that, by his purchase, he was participating in a transaction connected with fraudulent evasion of VAT, and to do so even where the transaction in question meets the objective criteria which form the basis of the concepts of 'supply of goods effected by a taxable person acting as such' and 'economic activity'. 60. It follows from the foregoing that the answer to the questions must be that where a recipient of a supply of goods is a taxable person who did not and could not know that the transaction concerned was connected with a fraud committed by the seller, art 17 of the Sixth Directive must be interpreted as meaning that it precludes a rule of national law under which the fact that the contract of sale is void—by reason of a civil law provision which renders that contract incurably void as contrary to public policy for unlawful basis of the contract attributable to the seller—causes that taxable person to lose the right to deduct the VAT he has paid. It is irrelevant in this respect whether the fact that the contract is void is due to fraudulent evasion of VAT or to other fraud. 61. By contrast, where it is ascertained, having regard to objective factors, that the supply is to a taxable person who knew or should have known that, by his purchase, he was participating in a transaction connected with fraudulent evasion of VAT, it is for the national court to refuse that taxable person entitlement to the right to deduct.”
“[59] The test in Kittel is simple and should not be over-refined. It embraces not only those who know of the connection but those who “should have known”
“[28] Since the right to deduct is fundamental to the system of VAT because it ensures that the charge is limited to the value added at each stage of the supply and because it ensures fiscal neutrality, it may not, in principle, be limited; any derogation from the principle of the right to deduct tax must be interpreted strictly (see Magoora sp zoo v Dyrektor Izby Skarbowej w Krakowie (Case C-414/07 )[2008] ECR I-10921 ). Moreover, the right must be exercisable immediately in respect of all taxes charged on input transactions. Since the right arises immediately the taxable person pays tax (input tax) to his supplier, the principle of legal certainty demands that he knows when he enters into the transaction that it is within the scope of the tax and that his liability will be limited to the amount by which any output tax he may be liable to pay, on making a supply, exceeds the input tax he has paid. The objective criteria determine both the scope of the tax and the circumstances in which the right to deduct arises.”
“(1) A penalty is payable by a person (P) where - (a) P gives HMRC a document of a kind listed in the Table below, and (b) Conditions 1 and 2 are satisfied. (2) Condition 1 is that the document contains an inaccuracy which amounts to, or leads to – (a) an understatement of a liability to tax, (b) a false or inflated statement of a loss, or (c) a false or inflated claim to repayment of tax. (3) Condition 2 is that the inaccuracy was careless (within the meaning of paragraph 3) or deliberate on P's part.”
“(1) For the purposes of a penalty under paragraph 1, inaccuracy in a document given by P to HMRC is – (a) “careless” if the inaccuracy is due to failure by P to take reasonable care, (b) “deliberate but not concealed” if the inaccuracy is deliberate on P’s part but P does not make arrangements to conceal it….,”
