Indexation: basic computations
The allowance is normally the amount arrived at by applying the indexation factor to each item of expenditure (or value), within TCGA92/S38 (1)(a) and (b), incurred or treated as incurred by the person disposing of the asset. Although in practice computations often treat the allowance as an addition to cost, in strictness the allowance is deducted from the gain in order to arrive at the chargeable gain, and computations sent to taxpayers or their agents should be laid out in the correct form.
