tight so tight its amazing, page-18

If you are in the "business of trading" then you cannot access the 50% CGT discount as your profit will be on revenue account.
However if you hold the shares on capital account (ie not carrying on a trading business) and longer than 12months the sale of the shares will be a capital gain and you will be eligible for the 50% CGT discount.

Basically to be in the "business of share trading" you have to carry on trading in a business like manner. Keep records, plan to make profits from sale of shares (with the longer term not in the picture). etc etc.

I prefer holding on capital account, as the 50% CGT discount is the most effective way to lower your tax liability on sales. I am of the view of let your profits run and cut of your losses, so more often than not i will hold a profit making share sfor longer than 12M and cut my tax back 50% utilising the discount available. And also, any expenses you incur in maintaining or purchasing the share you just add to the cost of the share to work out your overall profit/loss.

Hope this helps a bit.
