CG26510 - Arrival in and departure from UK: temporary non-residence: gains or losses excluded from TCGA92/S10A* - year of departure 2013-14 or later
Where assets have been acquired by an individual during a residence period when they do not have sole UK residence, and that residence period falls within a period of temporary non-residence, then any gains realised on those assets in the period of temporary non residence will in general be excluded from the scope of TCGA92/S10A* and hence from the charge under TCGA92/S2*, see CG26600. Similarly losses accruing in such circumstances will not be allowable.
This exclusion from the scope of TCGA92/S10A* will not apply to assets held in a non-resident trust or closely controlled non resident company.
There are further exceptions to the general rule. Where an asset held before departure stands at a gain, and that gain is rolled-over or its accrual is otherwise deferred until another asset is disposed of during the period of absence, then TCGA92/S10A* contains provisions which prevent such gains escaping tax. See CG26610 and CG26630.
*These provisions were re-written for disposals from 6 April 2019 see CG10150.
