No initial allowance shall be made by virtue of subsection (1) above.

Where, after the setting up and before the permanent discontinuance of a trade, profession or vocation which at any time is carried on in partnership, anything is done for the purposes thereof, any allowance or charge which, if the trade, profession or vocation had at all times been carried on by one and the same person, would have fallen to be made to or on him under any of the provisions of Parts I, IV to VI and this Part shall be made to or on the person or persons from time to time carrying on that trade, profession or vocation, and the amount of any such allowance or charge shall be computed as if that person or those persons had at all times been carrying on the trade, profession or vocation and as if everything done to or by his or their predecessors in the carrying on thereof had been done to or by him or them.

This section shall, with the necessary adaptations, apply in relation to the occupation of woodlands the profits or gains of which are assessable under Schedule D as it applies in relation to a trade.
