M1(1)In computing the charge to tax in respect of sums received by any person which are chargeable to tax by virtue of section 103 or 104(1) (including amounts treated as sums received by him by virtue of section 103(4)), there shall be deducted from the amount which, apart from this subsection, would be chargeable to tax—
(a)any loss, expense or debit (not being a loss, expense or debit arising directly or indirectly from the discontinuance itself) which, if the trade, profession or vocation had not been discontinued, would have been deducted in computing for tax purposes the profits or gains of the person by whom it was carried on before the discontinuance, or would have been deducted from or set off against those profits or gains as so computed, and
(b)any capital allowance to which the person who carried on the trade, profession or vocation was entitled immediately before the discontinuance and to which effect has not been given by way of relief before the discontinuance.
(2)No amount shall be deducted under subsection (1) above if that amount has been allowed under any other provision of the Tax Acts.
(3)No amount shall be deducted more than once under subsection (1) above; and—
(a)any expense or debit shall be apportioned between a sum chargeable under section 103 and a sum chargeable under section 104(1) in such manner as may be just;
(b)as between sums chargeable, whether under section 103 or 104(1), for one chargeable period and sums so charged for a subsequent chargeable period, any deduction in respect of a loss or capital allowance shall be made against sums chargeable for the earlier chargeable period;
(c)subject to paragraph (b) above, as between sums chargeable for any chargeable period under section 103 and sums so chargeable under section 104(1), any deduction in respect of a loss or capital allowance shall be made against the last-mentioned sums rather than the first-mentioned;
but, in the case of a loss which is to be allowed after the discontinuance, not so as to authorise its deduction from any sum chargeable for a chargeable period preceding that in which the loss is incurred.
(4)In computing the charge to tax in respect of sums received by any person which are chargeable to tax by virtue of section 104(4), there shall be deducted any expense or debit which is not otherwise allowable and which, but for the change in basis, would have been deducted in computing for tax purposes the profits or gains of the trade, profession or vocation, but no amount shall be deducted more than once under this subsection.
