“The mere acquisition of financial holdings in other undertakings does not amount to the exploitation of property for the purposes of obtaining income therefrom on a continuing basis because any dividend yielded by that holding is merely the result of ownership of the property. It is otherwise where the holding is accompanied by direct or indirect involvement in the management of the companies in which the holding has been acquired, without prejudice to the rights held by the holding company as shareholder. ... art 4 of the Sixth Directive [EC Council Directive 77/388] is to be interpreted as meaning that a holding company whose sole purpose is to acquire holdings in other undertakings, without involving itself directly or indirectly in the management of those undertakings, without prejudice to its rights as a shareholder, does not have the status of a taxable person for the purpose of VAT and therefore has no right to deduct tax under Art 17 of the Sixth Directive.”
