(2) An assessment under this paragraph must be made within the time limits provided for in section 77 and may not be made after the later of— (a) 2 years after the time when a notification of the acquisition of the goods in question is given to the Commissioners by the person who is required to give one by regulations under paragraph 73(4), and (b) one year after evidence of the facts, sufficient in the opinion of the Commissioners to justify the making of the assessment, comes to their knowledge, but (subject to section 77) where further such evidence comes to the Commissioners' knowledge after the making of an assessment under this section, another assessment may be made under this paragraph, in addition to any earlier assessment. (3) Where an amount has been assessed and notified to any person under this paragraph, it is, subject to the provisions of this Act as to appeals, deemed to be an amount of VAT due from the person and may be recovered accordingly, unless, or except to the extent that, the assessment has subsequently been withdrawn or reduced.
