CG50606 - Share identification rules: section 104 holding: indexation allowance


TCGA92/S110

Subject to the important modification described in CG50607, the indexation allowance due is computed by comparing the Retail Prices Index at the date of the operative event (RE) with the Retail Prices Index at the date of the previous operative event (RL) using the formula



RE - RL

RL

If the RPI has remained the same or fallen no indexation allowance is due.

Unlike TCGA92/S54(1) there is no requirement to round the indexation factor to three decimal places. In practice you should allow taxpayers to use the published indexation factors.
