This is my first time submitting a capital gains report to HMRC.

I understand we need to complete the SA108 form with details of number of transactions, gains, losses etc. However it states at the top that we should also submit “evidence of your computations, including details of each gain or loss…”.

I have rather a lot of transactions (thousands) so are they really expecting me to submit all of these as well? I wonder what others have done when there are a lot of transactions in to support the final numbers.

Thanks in advance
