Tax Return Due 31 October: Sort a Year of Receipts in One Afternoon

First, check which deadline is yours

31 October is the date for people who lodge their own return. If you use a registered tax agent, the agent usually has a later lodgment program, but you generally need to be on their books before 31 October to get it. If you have not engaged one yet and the date is close, that phone call comes before anything in this article.

If you are going to be late, lodging late is still better than not lodging. The ATO website sets out what happens and how to ask for more time.

Hour one: get everything into one pile

• Paper. Wallet, glovebox, the drawer. Photograph each one now. Thermal paper fades, and a receipt you cannot read is a receipt you do not have.
• Photos. Search your camera roll for "receipt". iPhone finds most of them by itself.
• Email. Search for "tax invoice", "receipt" and "order confirmation" since 1 July last year. Software, subscriptions, tools and courses mostly live here.
• Bank statements. Export the PDF for the financial year from your bank app. It is not proof of what you bought, but it is the best list of what you forgot.

A statement line shows that money left the account and where it went. It does not show what the purchase was or how much of it was for work, which is why it supports a record rather than replacing one.

Hour two: decide what each one was for

This is the step people skip, and it is the one that decides the size of the claim. For every expense, the question is the same: was it for work, for you, or for both?

• Work. Counts in full, if you paid for it yourself and were not reimbursed.
• Mixed. A phone, internet, a laptop. Only the work share counts, and you need a reasonable basis for the percentage, such as a four-week diary of use.
• Personal. Does not count. Keeping it in the same list is still useful, because it stops you wondering about it again next week.

If your total work-related claim is over $300, you need written evidence for all of it, not only the part above $300. The rules are in plain English in how long to keep receipts for tax in Australia.

Hour three: find the gaps, then stop

Go down the bank statement once. For each line that looks like work, check there is a record with a receipt behind it. Where there is not, look for the email, the supplier's account page or the shop's reprint. Some you will not find. Note them and move on: an afternoon spent hunting one $14 receipt is how the whole job stays unfinished.

Then total it by category. That is what myTax asks for and what an accountant wants first: the deductible total, a list behind it, and the receipts behind the list.
