Finance Act 1984

10 (1) Except in a case falling within paragraph 9 above, so far as it relates to the old asset and the new asset, the relevant transaction shall be treated for the purposes of the principal Act as not involving any disposal of the old asset but—

(a) there shall be calculated the chargeable gain or allowable loss that would have accrued if, at the time of the relevant transaction, the old asset had been disposed of for a consideration equal to its market value immediately before that transaction; and

(b) subject to paragraph 11 below, the whole or a corresponding part of the chargeable gain or allowable loss mentioned in paragraph (a) above shall be deemed to accrue on a subsequent disposal of the whole or part of the new asset (in addition to any gain or loss that actually accrues on that disposal); and

(c) if that subsequent disposal is within section 67 of the principal Act, that section shall have effect only in relation to any gain or loss that actually accrues and not in relation to any gain or loss which is deemed to accrue by virtue of paragraph (b) above.

(2) Paragraphs (b) and (c) of sub-paragraph (1) above shall not apply to any disposal falling within the provisions of—

(a) section 44(1) of the principal Act (disposals between husband and wife); or

(b) section 49(4) of that Act (disposals by personal representatives to legatees); or

(c) section 273(1) of the Taxes Act (disposals within a group of companies);

but a person who has acquired the new asset on a disposal falling within those provisions (and without there having been a previous disposal falling within those provisions or a devolution on death) shall be treated for the purposes of paragraphs (b) and (c) of sub-paragraph (1) above as if the new asset had been acquired by him at the same time and for the same consideration as, having regard to paragraph 8 above, it was acquired by the person making the disposal.
