ATO warning of fake ABN and TFN scams

The ATO has just recently reported an increase in fake websites offering to provide tax file numbers (TFNs) and Australian Business Numbers (ABNs) for a fee but then failing to provide the service – leaving taxpayers out of pocket. The fake TFN and ABN services are typically advertised on social media platforms like Facebook, Twitter, and Instagram. The advertisements offer to obtain your TFN or ABN for a fee. Instead of delivering this service, the scammer uses these fraudulent websites to steal both money and personal information.

It is free, quick, and easy to use government services to apply for a TFN through the ATO or apply for an ABN through the Australian Business Register (ABR).

ATO Assistant Commissioner Tim Loh said:

“Scammers are constantly developing new ways to target the community, and we expect to see more of these malicious attempts to steal identity details in the lead up to tax time.”

In 2021, more than 50,000 people reported ATO impersonation scams with victims losing a total of more than $800,000.

“We are concerned about a recent increase in the number of victims reporting scams around TFN and ABN applications. We are also still seeing scammers impersonating the ATO, making threats, demanding the payment of fake tax debts or claiming a TFN has been ‘suspended’ due to fraud.

Those who apply for a TFN or ABN through a tax agent should always check that the tax agent is registered with the Tax Practitioners Board

We are encouraging everyone to be on alert and take the time to remind family and friends to be on the lookout and stay safe online, so you don’t fall victim to a scam this tax time.”

Tips to protect yourself from scammers

1. Know your tax affairs

You will be notified about your tax debt before it is due. Check if you have a legitimate debt owed by logging into your myGov account via an independent search or by calling your tax agent if you have one (on a number sourced independently).

2. Guard your personal and financial information

Be careful when clicking on links, downloading files, or opening attachments. Only give your personal information to people you trust and don’t share it on social media.

3. If you are unsure, don’t engage

If a call, SMS, or email leaves you wondering if it is genuine, don’t reply. Instead, you should phone ATO’s dedicated scam line 1800 008 540 to check if the communication is legitimate. You can also verify or report a scam online at You can also visit to get information about scams (not just tax scams).
