Should I take copies of receipts as proof for the tax department?
A lot of my receipts (Aust Post) are printed on thermal paper and fade over time. Do I need to provide copies of my receipts as proof when dealing with the ATO and tax matters?
Yes. If you are audited the ATO can ask for proof of your expenditure. There are a number of apps where you can take a photo of it to store it, or you can scan them and keep an electronic copy. It's fine if you want to put several together for one A4 page photocopy as well.
Generally you need to Tax compliance info for 5 years and needproof in form of electronic or printed copy of every payment you claim against.
