I wonder if for tax purposes, is income realised when funds are withdrawn into a bank account or when a profitable position has been closed?
From what I understand so far, it is probably the latter. The terms 'revenue account' is in use here: https://community.ato.gov.au/t5/Personal-tax-questions/CFD-taxation-on-gains-and-losses/td-p/4458
I see references to this URL, which I have not been able to access http://law.ato.gov.au/atolaw/view.htm?docid=TXR/TR200515/NAT/ATO/00001
Any help or pointers to official information appreciated :)
