Unjust enrichment: Primary legislation: Section 80(3) to (3C) of the VAT Act 1994
The power to refuse claims made under section 80 of the VAT Act 1994 is contained in subsections (3) to (3C) of that section and provide as follows:
“(3) It shall be a defence, in relation to a claim under this section by virtue of subsection (1) or (1A) above, that the crediting of an amount would unjustly enrich the claimant.
(3A) Subsection (3B) below applies for the purposes of subsection (3) above where—
(a) an amount would (apart from subsection (3) above) fall to be credited under subsection (1) or (1A) above to any person (“the taxpayer”), and
(b) the whole or a part of the amount brought into account as mentioned in paragraph (b) of that subsection has, for practical purposes, been borne by a person other than the taxpayer.
(3B) Where, in a case to which this subsection applies, loss or damage has been or may be incurred by the taxpayer as a result of mistaken assumptions made in his case about the operation of any VAT provisions, that loss or damage shall be disregarded, except to the extent of the quantified amount, in the making of any determination—
(a) of whether or to what extent the crediting of an amount to the taxpayer would enrich him; or
(b) of whether or to what extent any enrichment of the taxpayer would be unjust.
(3C) In subsection (3B) above—
“the quantified amount” means the amount (if any) which is shown by the taxpayer to constitute the amount that would appropriately compensate him for loss or damage shown by him to have resulted, for any business carried on by him, from the making of the mistaken assumptions; and
“VAT provisions” means the provisions of—
(a) any enactment, subordinate legislation or Community legislation (whether or not still in force) which relates to VAT or to any matter connected with VAT; or
(b) any notice published by the Commissioners under or for the purposes of any such enactment or subordinate legislation.”
