Hi There, I am a consumer that had a service done in Feb 2025. I have been requesting an invoice since the service, only to receive it in Sept 2025 backdated to Feb 2025 (6 months later).

I then requested an itemised corrected invoice, with a reply 5 months later in Feb 2026, same invoice number, backdated to 4 days after the Sept 2025 invoice. It had changes to price, descriptions, fictitious part numbers, charging for items that I had supplied etc.

For the fictitious part, I was provided a suppliers invoice without an ABN as a proof of purchase.

There was no other information provided to explain the changes, what should I do?


I am disputing the invoice through civil proceedings, but as you can see, this is dragging out. Is there anything more I need to do?

Hi @nomads64,


This is mainly an Office of Fair Trading or ACCC issue, not something we regulate directly.


From a tax perspective, businesses must provide a tax invoice if:

  • the supply is taxable and $82.50 or more (including GST)
  • the customer requests it.

But we don’t determine whether the pricing, delays, or changes on an invoice are valid – that falls under consumer law.


If you're concerned about the business’s tax compliance, you can check if they have a valid ABN. Take a look at the ABN lookup. You'll be able to search their business details and confirm which ABN best matches the supplier.

Agree. I am currently going through a civil proceeding, so I have that covered. I can see that the second invoice was manipulated to have the same GST as the first. I can also prove the fraudulent component i.e. criminal act, so I am filing a police report as well. Once I have the details finalised, I will also be filing an ATO report.


The most important question I have at the moment is:

Even though I am a consumer, does the business have to provide an invoice if I request it?


I understand that this is important for business to business for GST reporting. However I can not find anything about regular consumers. The closest i get is that an invoice can be issued up to 6 years later under Australian Consumer Law. It does not state anything about responding to a request for an invoice. This is partially covered, that a consumer may request an itemised invoice within 30 days of receipt of the initial invoice. Is there something I am missing......


The second invoice has the same invoice number, however an amendment was not documented. Isn't that a requirement of the ATO for Tax reporting processes, especially if it across financial years?

Hi @nomads64


The short answer is yes, with a few conditions.


If they are registered for GST and the purchase is more than $82.50 they are require to provide a tax invoice within 28 days of you requesting one in writing. If they are refusing to provide you with an invoice or you think they are keeping fraudulent records you can lodge a tip off form.
