While working as an assistant accountant for a group of companies, how can I gain experience to be able to claim element (b) "Prepare or contribute to the computation or assessment of tax individuals" of PO15 "Tax Computations and Assessment"? I've got experience in all of the other elements as they deal with corporation tax and VAT. I'm only missing element (b) to complete this objective. There are no other technical objectives that I've not claimed already or that I've got any exposure at all.
Would anyone have a suggestion?
