This Practice Note written by Dhana Sabanathan, partner at Michelmores LLP, considers the special provisions contained in section 90 of the Taxation of Capital Gains Act 1992 (TCGA 1992) that apply where all or part of the settled property of a settlement, is transferred to another settlement, and the transferor settlement has TCGA 1992, s 1(3) amounts (‘trust gains’) and offshore income gains (OIGs). This note also briefly considers the circumstances in which TCGA 1992, s 90 does not apply.
