Hello, I am Keith, one of the experts on Just Answer, and pleased to be able to help you with your question.
On the date of sale, that is the disposal date for Capital Gains Tax (CGT) purposes.
I do hope that you have found my reply of assistance..
Possibly; if you cast your mind back to the old Stock Exchange share trading system when settlement was made a couple of weeks later the sale still crystalised for CGT purposes on the selling date. The following rule applies: TCGA 1992, s 48 provides that, where the amount of the future consideration is ascertainable, as it is in this case, the full consideration is subject to tax.
I am so sorry to have to rain on your parade.
Thank you for your support.
