What counts as proof of purchase in Australia?

Proof of purchase is whatever reasonably establishes that you bought this item, from this business, at this time. Australian law does not require it to be a paper receipt, and the list of what works is longer than most people — including a fair number of retail staff — realise.

The list#

Any of these can establish a purchase:

• a cash register receipt
• a handwritten receipt
• a tax invoice
• a credit or debit card statement showing the transaction
• a lay-by agreement
• a confirmation or receipt number for a phone or internet transaction
• a warranty card showing the supplier's details, the date and the amount
• a serial or production number tied to your purchase in the supplier's own system

Photos and scans of any of the above work too. Nothing in the law privileges the original paper, and where a thermal receipt has faded to blank, the photo you took of it is straightforwardly better evidence.

What a compliant receipt has to show#

When a business does issue proof of transaction, it must include:

• the supplier's identity, and their ABN or ACN
• the date of the supply
• a description of what was supplied
• the price

For services, you can also ask for an itemised bill setting out how the price was calculated — and the business has seven days to give it to you, free of charge.

Not all proof is equally strong#

Everything on the list is acceptable. That does not make it equally useful, and it is worth knowing which of your evidence is doing the heavy lifting.

The gap in a bank statement is the item. It proves you spent $899 at that retailer on that date; it doesn't prove the $899 was this washing machine. Most of the time that inference is obvious enough to be accepted. When it isn't, pairing the statement with the original box, a serial number or a warranty card closes it.

The ATO applies a stricter test to the same receipt#

If you are keeping the receipt for a tax deduction rather than a return, note that the two systems want different things.

The ACCC's question is did you buy it here. The ATO's question is what exactly was it, when, and from whom — and its written-evidence rules require the document to show the supplier's name, the amount, the nature of the goods or services, the date the expense was incurred, and the date of the document.

The practical upshot: a bank statement that satisfies a retailer for a warranty claim will generally not satisfy the ATO as written evidence, because it doesn't describe what was bought. If a receipt matters for tax, keep the receipt.

That is covered in detail in how long you need to keep receipts for the ATO.

If you have nothing at all#

It happens — cash purchase, receipt long gone, no card record. Options, in rough order of how often they work:

1. Ask the retailer to look it up. Loyalty programs, store accounts and card-linked lookups recover a surprising number of transactions.
2. Check your email. Emailed receipts are now the default at many retailers, and it may be there under a sender name you'd never search for.
3. Find the serial number. For appliances and electronics, manufacturers and retailers often have it linked to a sale or a registration.
4. Check whether you registered the warranty. A registration record is itself dated evidence.

If none of those land, you are relying on the business's discretion. Many will help, especially where the fault is obvious and the product is clearly theirs — but at that point it is goodwill, not a right.

The takeaway#

Proof of purchase is a category, not a document. For consumer guarantee claims, several things qualify and a card statement is genuinely among them. For tax, the standard is narrower and the itemised receipt is what you need.

Keep something that shows the shop, the date, the item and the amount, and you're covered for both.
