“(1) Where a company resident outside the united kingdom (‘the overseas company’) pays a dividend to [ a UK resident company ] (‘the relevant company’) and the overseas company is related to the relevant company, then for the purpose of allowing credit under any arrangements against corporation tax in respect of the dividend, there shall be taken into account, as if it were tax payable under the law of the territory in which the overseas company is resident – any United kingdom tax or corporation tax payable by the overseas company in respect of its profits; and any tax which, under the law of any other territory, is payable by the overseas company in respect of its profits.”
