(a)of assets situated in the United Kingdom and used in or for the purposes of the trade at or before the time when the capital gain accrued, or
(b)of assets situated in the United Kingdom and used or held for the purposes of the branch or agency at or before that time, or assets acquired for use by or for the purposes of the branch or agency.
(2)Subsection (1) above does not apply unless the disposal is made at a time when the person is carrying on the trade in the United Kingdom through a branch or agency.
(3)For the purposes of corporation tax the chargeable profits of a company not resident in the United Kingdom but carrying on a trade or vocation there through a branch or agency shall be, or include, such chargeable gains accruing on the disposal of assets situated in the United Kingdom as are by this section made chargeable to capital gains tax in the case of an individual not resident or ordinarily resident in the United Kingdom.
(4)This section shall not apply to a person who, by virtue of Part XVIII of the Taxes Act (double taxation relief agreements), is exempt from income tax or corporation tax chargeable for the chargeable period in respect of the profits or gains of the branch or agency.
(5)This section shall apply as if references in subsections (1) and (2) above to a trade included references to a profession or vocation, but subsection (1) shall not apply in respect of chargeable gains accruing on the disposal of assets only used in or for the purposes of the profession or vocation before 14th March 1989 or only used or held for the purposes of the branch or agency before that date.
(6)In this Act, unless the context otherwise requires, “branch or agency” means any factorship, agency, receivership, branch or management, but does not include any person within the exemptions in section 82 of the Management Act (general agents and brokers).
