CG42430 | Migration of companies before January 2020: reduction of recovery charge for unused losses
From HM Revenue & Customs · Capital Gains Manual
CG42400 explains how exit charges under TCGA92/S185 (CG42370) that arose before 1 January 2020 that are postponed under TCGA92/S187 (CG42390) may be recovered on the happening of certain events.
The chargeable gain of the principal company may be reduced if the subsidiary company has unused allowable losses provided
they have not been taken into account in computing the postponed gain, and
an election is made, under TCGA92/S187 (5), by the two companies within two years of the event which gave rise to the charge.
A separate election is required in respect of each such event.
If the subsidiary company makes allowable losses after the relevant time, for example on assets of a UK permanent establishment, an election under TCGA92/S187 (5) may include these losses (provided they are unused).
The ‘relevant time’ is defined by TCGA92/S185 (1) as the time at which the chargeable company ceases to be resident in the UK, see CG42370.
