110Unjustified enrichment: further provision
(1)This section applies where—
(a)there is an amount paid by way of tax which (apart from section 109) would fall to be repaid or discharged to any person (“the taxpayer”), and
(b)the whole or a part of the cost of the payment of that amount to Revenue Scotland has, for practical purposes, been borne by a person other than the taxpayer.
(2)Where, in a case to which this section applies, loss or damage has been or may be incurred by the taxpayer as a result of mistaken assumptions made in the taxpayer’s case about the operation of any provisions relating to a tax, that loss or damage is to be disregarded, except to the extent of the quantified amount, in the making of any determination—
(a)of whether or to what extent the repayment or discharge of an amount to the taxpayer would enrich the taxpayer, or
(b)of whether or to what extent any enrichment of the taxpayer would be unjust.
(3)In subsection (2) “the quantified amount” means the amount (if any) which is shown by the taxpayer to constitute the amount that would appropriately compensate the taxpayer for loss or damage shown by the taxpayer to have resulted, for any business carried on by the taxpayer, from the making of the mistaken assumptions.
(4)The reference in subsection (2) to provisions relating to a tax is a reference to any provisions of—
(a)any enactment, subordinate legislation or EU legislation (whether or not still in force) which relates to that tax or to any matter connected with it, or
(b)any notice published by Revenue Scotland under or for the purposes of any such enactment or subordinate legislation.
