Subject to subsection (3) below, where an asset acquired by a person otherwise than as trading stock of a trade carried on by him is appropriated by him for the purposes of the trade as trading stock (whether on the commencement of the trade or otherwise) and, if he had then sold the asset for its market value, a chargeable gain or allowable loss would have accrued to him, he shall be treated as having thereby disposed of the asset by selling it for its then market value.

If at any time an asset forming part of the trading stock of a person’s trade is appropriated by him for any other purpose, or is retained by him on his ceasing to carry on the trade, he shall be treated as having acquired it at that time for a consideration equal to the amount brought into the accounts of the trade in respect of it for tax purposes on the appropriation or on his ceasing to carry on the trade, as the case may be.

Subject to subsection (4) below, subsection (1) above shall not apply in relation to a person’s appropriation of an asset for the purposes of a trade if he is chargeable to income tax in respect of the profits of the trade under Case I of Schedule D, and elects that instead the market value of the asset at the time of the appropriation shall, in computing the profits of the trade for purposes of tax, be treated as reduced by the amount of the chargeable gain or increased by the amount of the allowable loss referred to in subsection (1), and where that subsection does not apply by reason of such an election, the profits of the trade shall be computed accordingly.

If a person making an election under subsection (3) is at the time of the appropriation carrying on the trade in partnership with others, the election shall not have effect unless concurred in by the others.
