CGT indexation allowance to disappear from 1 January 2018.
This measure means that when a company makes a capital gain on or after 1 January 2018, the indexation allowance that is applied in order to determine the amount of the chargeable gain will be calculated up to December 2017.
Without this measure, indexation allowance would be calculated up to the month in which the disposal of the asset occurs
The measure aligns the treatment of capital gains by companies with that for individuals and non-incorporated businesses for whom indexation allowance was abolished in 2008.
