Nick, you're Education piece highlights the need for good record keeping. A couple of questions: a) Must the original recipts/documents be kept or is a diary/ledger/spreadsheet sufficient ? b) Can these documents be kept electronically ? i.e. scan all relevent docs to PDF and then save everything to CD/DVD. Will the ATO accept scanned copies ? Actually, another question. Would you advise keeping everything sorted by Tax Year or by asset ?
