Article 2(1)(a), Article 9(1) Article 14(1) and Articles 73 and 273 of the Council Directive 2006/112/EC and the principle of fiscal neutrality must be interpreted as not precluding national legislation, such as that at issue in the main proceedings, under which, where goods are not in the warehouse of the taxable person to whom they have been supplied and the tax documents of relevance to those goods have not been recorded in the accounts of that taxable person, tax authorities may presume that the taxable person subsequently sold those goods to third parties and determine the taxable amount of the sale of those goods according to the factual information at hand pursuant to rules not provided for in that directive. It is, however, for the referring court to ascertain whether the provisions of the national legislation go further than is necessary to ensure the correct collection of VAT and to prevent evasion.
