Ann: Quarterly Activities and Cashflow Report, page-179

I have just a 'normal' account - not a trust or super fund.... This is what I believe is correct:

Any gains or losses you made in a tax year are assessed at the end of financial year.

Any stock you held over a year and gained on is assessed at 50% CGT. If less than a year it is assessed at 100% of the gain.

If, after taking into account any losses, you made a capital gain overall, that would be taxed at your marginal rate.

If you make a loss overall, that loss is carried forward and claimed against any gains the following year... and so on.

It does get complicated and it is best to get an accountant's advice. I'm not an accountant - but this is how it has been working for me.
