The Capital Gains Tax (Annual Exempt Amount) Order 2017
Section 3 of the Taxation of Chargeable Gains Act 1992 (c.12) (“TCGA”) provides that an individual shall not be chargeable to capital gains tax in respect of so much of his taxable amount for any year of assessment as does not exceed the exempt amount for that year. Subsection (2) specifies the annual exempt amount (“AEA”) as £11,100. Subsection (3) provides that that amount is increased, unless Parliament otherwise determines, in relation to a tax year by reference to a formula prescribed by subsection (3B) if there has been a relevant increase in the consumer prices index (“CPI”).
