“24. (1) Subject to the following provisions of this section, "input tax", in relation to a taxable person, means the following tax, that is to say— (a) VAT on the supply to him of any goods or services; (b) VAT on the acquisition by him from another member State of any goods; and (c) VAT paid or payable by him on the importation of any goods from a place outside the member States, being (in each case) goods or services used or to be used for the purpose of any business carried on or to be carried on by him… (6) Regulations may provide— (a) for VAT on the supply of goods or services to a taxable person, VAT on the acquisition of goods by a taxable person from other member States and VAT paid or payable by a taxable person on the importation of goods from places outside the member States to be treated as his input tax only if and to the extent that the charge to VAT is evidenced and quantified by reference to such documents as may be specified in the regulations or the Commissioners may direct either generally or in particular cases or classes of cases;...”
“29. (1) Subject to paragraph (2) below, and save as the Commissioners may otherwise allow or direct either generally or specially, a person claiming deduction of input tax under section 25(2) of the Act shall do so on a return made by him for the prescribed accounting period in which the VAT became chargeable. (2) At the time of claiming deduction of input tax in accordance with paragraph (1) above, a person shall, if the claim is in respect of— (a) a supply from another taxable person, hold the document which is required to be provided under regulation 13;… provided that where the Commissioners so direct, either generally or in relation to particular cases or classes of cases, a claimant shall hold, instead of the document or invoice (as the case may require) specified in sub-paragraph 30 (a)… above, such other documentary evidence of the charge to VAT as the Commissioners may direct”
“[54.] As the Court has already observed, preventing tax evasion, avoidance and abuse is an objective recognised and encouraged by the Sixth Directive (see Joined Cases C-487/01 and C-7/02 Gemeente Leusden and Holin Groep[2004] ECR I-5337 , paragraph 76). Community Law cannot be relied on for abusive or fraudulent ends (see, inter alia,Case C-367/96 Kefalas and Others[1998] ECR I-2843 , paragraph 20; Case C- 373/97 Diamantis[2000] ECR I-1705 , paragraph 33; andCase C-32/03 Fini H[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, Case 268/83 Rompelman [1985] ECR 655 , paragraph 24;Case C-110/94 INZO[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, Article 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.” [7.] In Mobilix Ltd v Commissioners for Her Majesty’s Revenue and Customs[2010] EWCA Civ 517 ,[2010] STC 1436 the Court of Appeal had to consider the proper interpretation and application of the ECJ’s decision in Kittel. Moses LJ, with whom Carnwath LJ (as he then was) and Sir John Chadwick agreed, considered the meaning of the words “should have known” and held as follows: “[51.] Once it is appreciated how closely Kittel follows the approach the court had taken six months before in Optigen , it is not difficult to understand what is meant when it is said that a taxable person ‘knew or should have known’ that by his purchase he was participating in a transaction connected with fraudulent evasion of VAT. In Optigen the Court ruled that despite the fact that another prior or subsequent transaction was vitiated by VAT fraud in the chain of supply, of which the impugned transaction formed part, the objective criteria, which determined the scope of VAT and of the right to deduct, were met. But they limited that principle to circumstances where the taxable person had ‘no knowledge and no means of knowledge’ (§ 55). The Court must have intended Kittel to be a development of the principle in Optigen . Kittel is the obverse of Optigen . The Court must have intended the phrase ‘knew or should have known’ which it employs in §§59 and 61 in Kittel to have the same meaning as the phrase ‘knowing or having any means of knowing’ which it used in Optigen (§55). [52.] If a taxpayer has the means at his disposal of knowing that by his purchase he is participating in a transaction connected with fraudulent evasion of VAT he loses his right to deduct, not as a penalty for negligence, but because the objective criteria for the scope of that right are not met. It profits nothing to contend that, in domestic law, complicity in fraud denotes a more culpable state of mind than carelessness, in the light of the principle in Kittel . A trader who fails to deploy means of knowledge available to him does not satisfy the objective criteria which must be met before his right to deduct arises.” [8.] Moses LJ considered the extent of knowledge that was required at [53]-[60]. He held at [55] that it was not sufficient for HMRC to show that the trader should have known that he was running a risk that his purchase was connected with fraud. He concluded: “[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’. Thus it includes those who should have known from the circumstances which surround their transactions that they were connected to fraudulent evasion. If a trader should have known that the only reasonable explanation for the transaction in which he was involved was that it was connected with fraud and if it turns out that the transaction was connected with fraudulent evasion of VAT then he should have known of that fact. He may properly be regarded as a participant for the reasons explained in Kittel. [60.] The true principle to be derived from Kittel does not extend to circumstances in which a taxable person should have known that by his purchase it was more likely than not that his transaction was connected with fraudulent evasion. But a trader may be regarded as a participant where he should have known that the only reasonable explanation for the circumstances in which his purchase took place was that it was a transaction connected with such fraudulent evasion.” [9]. Moses LJ held at [61]-[62] that this approach did not infringe the principle of legal certainty. As he said in [61]: “…It is difficult to see how an argument to the contrary can be mounted in the light of the decision of the court in Kittel . The route it adopted was designed to avoid any such infringement. A trader who decides to participate in a transaction connected to fraudulent evasion, despite knowledge of that connection, is making an informed choice; he knows where he stands and knows before he enters into that transaction that if found out, he will not be entitled to deduct input tax. The extension of that principle to a taxable person who has the means of knowledge but chooses not to deploy it, similarly, does not infringe that principle. If he has the means of knowledge available and chooses not to deploy it he knows that, if found out, he will not be entitled to deduct. If he chooses to ignore obvious inferences from the facts and circumstances in which he has been trading, he will not be entitled to deduct.” [10]. Moses LJ considered the facts of the appeals before the Court of Appeal at [67]-[80]. In relation to the appeal by Blue Sphere Global Ltd he held at [75]: “The ultimate question is not whether the trader exercised due diligence but rather whether he should have known that the only reasonable explanation for the circumstances in which his transaction took place was that it was connected to fraudulent evasion of VAT.” [11.] Moses LJ considered questions of proof at [80]-[85]. He held at [81] that the burden lay upon HMRC to prove the trader’s state of knowledge. He went on at [82]: “But that is far from saying that the surrounding circumstances cannot establish sufficient knowledge to treat the trader as a participant. As I indicated in relation to the BSG appeal, Tribunals should not unduly focus on the question whether a trader has acted with due diligence. Even if a trader has asked appropriate questions, he is not entitled to ignore the circumstances in which his transactions take place if the only reasonable explanation for them is that his transactions have been or will be connected to fraud. The danger in focussing on the question of due diligence is that it may deflect a Tribunal from asking the essential question posed in Kittel , namely, whether a trader should have known that by his purchase he was taking part in a transaction connected with fraudulent evasion of VAT. The circumstances may well establish that he was.” [12.] At paragraph [84] he said: “Such circumstantial evidence … will often indicate that a trader has chosen to ignore the obvious explanation as to why he was presented with the opportunity to reach a large and predictable reward over a short space of time.”
