Taxpayer conducts a retail business and performed a stocktake on 30 June 2021.

$250,000 - stock on hand (weighted average cost)

$240,000 - stock on hand (FIFO)

$270,000 - stock on hand (replacement value)

$440,000 - stock on hand (market selling value)

The taxpayer chose the FIFO method to value the stock on hand at year end.
