Computation for each disposal

[Sign]

You must provide a computation for each disposal of an asset which is not exempt from Capital Gains Tax. If you do not attach a computation you must provide the information in Any other information.

Hi, I am currently in the process of submitting my first self assessment.

Can i ask, the above statement HMRC make. the computation of each disposal, in what format should this look like?

Its just I have 134 individual trades of listed shares; 89 buys and 45 sales i 20/21 tax year. Can i submit a list of each purchase and each disposal in excel, then create a pdf showing all purchase/disposal costs and then calculate the grand total sum, or do I need to show the calculation for each disposal, all 45, relative to the individual purchase?

Thanks for any help.

Surely an Excel spreadsheet will show each disposal and the gain. Summarise on the return.
