On 21/11/2018, the ECJ ruled on VAT reference C-648/16*.
The Court stated that EU VAT law does not preclude national legislation which authorises tax authorities, in the event of serious differences between declared revenue and revenue estimated on the basis of sector studies, to use extrapolation, based on such sector studies, in order to determine the amount of turnover achieved by a taxable person and, consequently, to carry out a tax adjustment requiring the payment of additional VAT, provided that that legislation and its application enable the taxable person, in compliance with the principles of fiscal neutrality, proportionality and the right of defence, to challenge the results obtained by that method, on the basis of all of the evidence to the contrary available to him, and to exercise his right of deduction in accordance with the provisions in Title X of Directive 2006/2012.
