You can record a capital loss or gain tax event. When you get the capital return you reduce your purchase price. When it gets delisted you record the CGT event.
So for example if you bought 3 months ago at 5 cents, and the capital return is 4.3 cents, then you reduce your purchase price to 0.7 cents. When it gets delisted you can realise and record a capital loss of 0.7 cents.
I have seen in the past that companies make the capital return non taxable so then you wouldn't have to reduce the purchase price and can record a bigger capital loss, bit I haven't seen that mentioned here so that may not be on the cards.
I should flag obviously I am not a tax expert, this is just my rough understanding.
