Umm. Not quite, thank you for asking. My next prob now is this.
I have 3 shares that I have held for 1.5 years and 1 of them has grown overweight compared to the other 2. Now if I sell some of the overweight one and add to the other 2, does my "Purchase Date" start all over again?
The one you sell is up for debate between you and SARS as to whether it's income or CGT based on your intention etc.
Let's to simplify things say that you only buy one type of share instead of two.
You used to hold x shares.
You now hold x + y shares.
x shares are considered by SARS to be 1.5 years old.
y shares are considered by SARS to be 0 years old.
In other words you hold shares in a single company whose constituents are two different ages. In 1.5 years time you could sell x shares and pay only CGT. But if you sold x+y shares in 1.5 years time you'd pay CGT on x shares and would have to argue with SARS if your proceeds on y shares were CGT or income.
