Where an acquisition in Northern Ireland of goods from a member State is treated as taking place before IP completion day in accordance with section 12 of VATA 1994 (as it had effect immediately before IP completion day), the charge to VAT is to be treated as NI acquisition VAT under Schedule 9ZA to VATA 1994 for all purposes relating to things that arise, occur or are done in consequence of or in relation to that charge on or after IP completion day.
