Section 598 TCA 1997 provides a relief from capital gains tax (CGT), in certain circumstances, to an individual on a disposal of business assets. As the individual must be aged 55 or more, this is commonly referred to as ‘retirement relief’. Differing levels of relief apply to individuals aged 66 years or more at the time of disposal. With effect from 1 January 2025, these differing levels of relief apply to individuals aged 70 years or over.
