If Z Ltd started trading on 1 January 2017 then it would not have been part Beyonce’s group in the previous CAP,so how can we use the trading profit to set off the loss.
Whether it was a member of the group in the previous CAP is irrelevant – group relief is available from the date a company joins the 75% group – the issue then being to time apportion the period of loss and the period of profit for the corresponding accounting periods
