CG25510 | Non residents with a UK branch or agency: disposals
From HM Revenue & Customs · Capital Gains Manual
The disposal of an asset by an individual who is neither resident nor ordinarily resident* but is carrying on a trade, profession or vocation in the UK through a branch or agency will be an occasion of charge and the gain will be within the charge to Capital Gains Tax if
at the time of the disposal the trade, profession or vocation continues to be carried on through the branch or agency in the UK
and
the asset is situated in the UK
and
at or before the time of the disposal the asset has been
used in or for the purposes of the trade, profession or vocation
or
used or held or acquired for the purposes of the branch or agency.
CG25520 explains how gains on the disposal of assets of a UK branch or agency are computed.
Where the asset is residential property the reporting requirements in Sch2 FA19 do not apply . The gain would just need to be returned within the Self Assessment return for the year.
* For 2013/14 and subsequent years the rules within the Statutory Residence Test will apply and ordinary residence is not considered.
