"There must be a real connection, a nexus, between the expenditure and the business. It seems to me that the nexus, if it not to be benefit, must be directly referable to the purpose of the business."
"19 ... it should, first, be recalled, as the Court has previously held, that the existence of a direct and immediate link between a particular input transaction and one or more output transactions giving rise to the right to deduct is, in principle, necessary before the taxable person is entitled to deduct input VAT and in order to determine the extent of such entitlement ... The right to deduct VAT charged on the acquisition of input goods or services presupposes that the expenditure incurred in acquiring them is part of the cost components of the taxable output transactions giving rise to the right to deduct ... 20 It is however also accepted that a taxable person has a right to deduct even where there is no direct and immediate link between a particular input transaction and one or more output transactions giving rise to the right to deduct, where the costs of the services in question are part of his general costs and are, as such, components of the price of the goods or services which he supplies. Such costs do, in effect, have a direct and immediate link with the taxable person’s economic activity as a whole ... 21 It should, next, be noted, with regard to the nature of the ‘direct and immediate link’ which must exist between an input and an output transaction, that the Court has held that it would not be realistic to attempt to be more specific in that regard. In view of the diversity of commercial and professional transactions, it is impossible to give a more appropriate reply as to the method of determining in every case the relationship which must exist between the input and output transactions in order for input VAT to become deductible .... 22 Finally, it is apparent from the case-law that, in the context of the direct-link test, which the tax authorities and national courts are to apply, they should consider all the circumstances surrounding the transactions at issue ... and take account only of the transactions which are objectively linked to the taxable person’s taxable activity."
