Capital loss on second home

My wife sold a second property she owned at a capital loss. (a) Can she offset this loss against gains on shares in future years? (b) Is it sufficient to note the loss on the tax return or do we have to submit a claim using another form or letter? Many thanks for your guidance.

Hi,
Yes.  
Your wife will have to submit a claim to carry the losses forward, either in writing or in her self assessment tax return, if she completes one.  
In either case, both will require that you submit supporting evidence, including a calculation showing how the loss arises.
Thank you.
