Yeah did my head in to begin with ,wait till you buy shares in bundles at different prices .

The way I do it when I submit my returns to the accountant .

I bought 100 shares at 1.00
The shares increased to 2.00
To reduce my exposure I sell 50 at 2.00.
I have made a profit of 50 bucks on those shares . I have have made a capital gain of 50
I then declare that 50 on my tax return . Less any applicable fees etc

When I sell the other 50 I then do the same .
