29Recovery of overpayments
(1)Where an amount is liable to be repaid by a person or persons under section 28, the Board must give him, or each of them, a notice specifying the amount.
(2)The notice must state which of subsections (3) to (5) is to apply in relation to the amount or any specified part of the amount; and a notice may at any time be replaced by another notice containing a different statement.
(3)Where a notice states that this subsection applies in relation to an amount (or part of an amount), it is to be treated for the purposes of Part 6 of the Taxes Management Act 1970 (c. 9) (collection and recovery) as if it were tax charged in an assessment and due and payable by the person or persons to whom the notice was given at the end of the period of thirty days beginning with the day on which the notice is given.
(4)Where a notice states that this subsection applies in relation to an amount (or part of an amount), it may, subject to provision made by regulations, be recovered by deduction from payments of any tax credit under an award made for any period to the person, or either or both of the persons, to whom the notice was given.
(5)Where a notice states that this subsection applies in relation to an amount (or part of an amount), regulations under section 203(2)(a) of the Income and Corporation Taxes Act 1988 (c. 1) (PAYE) apply to it as if it were an underpayment of tax for a previous year of assessment by the person or persons to whom the notice was given.
