The Australian Tax Office (ATO) issued the warning amid the new financial year.

SMS and email scams are a form of identity theft, attempting to steal people’s usernames and passwords, and often leading to financial loss or identity theft.

Typically, the fraudulent communication will contain a hyperlink which, if clicked on, will direct the unsuspecting user to a fake myGov sign in page.

“We won’t send you an SMS or email with a link to log on to online services,” the ATO said.

“While we may use SMS or email to ask you to contact us, we will never ask you to return personal information through these channels.

“(Our services) should be accessed directly by typing ato.gov.au or my.gov.au into your browser.”

The government agency has warned Aussies to look out for some key red flags that can help distinguish a scam from a legitimate message.

Phrases used by scammers to encourage people to click on links include “You are due to receive an ATO Direct refund” and “You have an ATO notification”.

Recipients might also see messages urging them to update personal details to facilitate the processing of a tax return, or to verify an incoming tax deposit.

It’s also common for scam messages to contain phrases such as “ATO Refund failed due to incorrect BSB/Account number” and “Due to receive a refund, click here to receive a rebate”.

Phishing is a form of identity theft whereby scammers attempt to trick people into giving out personal information such as bank account numbers, passwords and credit card numbers.

According to Scamwatch there has been a reported loss of more than $19m to phishing scams so far this year, and more than $6.7m lost to identity theft scams.

The total amount lost nationally is likely much higher as not all losses are reported.

The ATO has urged Australians who receive any suspicious contacts claiming to be from the government agency to send them to ReportScams@ato.gov.au.
