(1)Where any person sustains a loss in any trade, profession, vocation or employment carried on by him either solely or in partnership, he may, by notice given within two years after the year of assessment, make a claim for relief from income tax on an amount of his income equal to the amount of the loss.
(2)Subject to section 492(2), relief may be given under subsection (1) above in respect of a person’s loss sustained in the last preceding year of assessment in any trade, profession, vocation or employment still carried on by him in the year for which the claim is made, in so far as relief in respect of that loss has not already been given under that subsection or otherwise; and where relief is claimed by virtue of this subsection it shall be given in priority to any relief under that subsection in respect of a loss sustained in the year for which the relief is claimed.
(3)Where there is in any year of assessment a change on which a trade, profession or vocation is treated under section 113(1) as permanently discontinued, and a person engaged in carrying it on immediately before the change continues to be so engaged immediately afterwards, it shall, notwithstanding the discontinuance, be treated as the same trade, profession or vocation for the purposes of subsection (2) above, except as respects the computation of profits or gains and losses.
(4)This section applies in relation to losses sustained in the occupation of woodlands in respect of which a person has elected under section 54 to be charged to income tax under Schedule D as it applies in relation to losses sustained in a trade.
