No Tugga,

You can only claim a capital gains loss against a capital gains, it does not go against any income what so ever.

Options....Wright it off against a profitable year when you cash out your shares or if you sell a house with profit after the cut off mid 80's then you can use it for that also....

It does last a life time and there is no expiry date, but unless you make capital gains profit you will never be able to use it.....

Hope this helps
