"(1) Where...any bodies corporate are treated as members of a group, any business carried on by a member of the group shall be treated as carried on by the representative member, and - ...(b) any...supply of goods and services by or to a member of the group shall be treated as a supply by or to the representative member... and all members of the group shall be liable jointly and severally for any VAT due from the representative member."
"After consulting the advisory committee on value added tax (hereafter, the 'VAT Committee'), each Member State may regard as a single taxable person any persons established in the territory of that Member State who, while legally independent, are closely bound to one another by financial, economic and organisational links"
"In this connection, treatment as a single taxable person precludes the members of the VAT group from continuing to submit VAT declarations separately and from continuing to be identified, within and outside their group, as individual taxable persons, since the single taxable person alone is authorised to submit such declarations (judgment in Ampliscientifica and Amplifin, C-162/07, EU:C:2008 ;301, paragraph 19). It follows that, in such a situation, the supplies of services made by a third party to a member of a VAT group must be considered, for VAT purposes, to have been made not to that member but to the actual VAT group to which that member belongs."
