The ATO issued a warning on Friday about the “emergence of a new tactic”.
Assistant Commissioner Karen Foat said in a statement scammers had been developing new ways to try and get money and personal information over the summer.
“We are seeing the emergence of a new tactic, where scammers are using an ATO number to send fraudulent SMS messages to taxpayers asking them to click on a link and hand over their personal details in order to obtain a refund,” she said.
This warning follows a previous one about people receiving phone calls from scammers claiming to be from the ATO. The calls claim the recipient of the call is under arrest.
The ATO said it received many reports of scammers last year “maliciously” manipulating caller ID so the phone number that appears is different to the number from which the call originated.
This method is known as “spoofing” and makes the call appear to be legitimate.
Ms Foat warned the scammers were not just after money, but were now after personal details to steal identities.
“Taxpayers should be wary of any phone call, text message or email asking you to provide login, personal or financial information, especially if you weren’t expecting it,” she said.
Anyone who is unsure about a text, phone call or email they have received can call 1800 008 540 to determine if it is legitimate or to report a scam. They can also visit Scamwatch for more information.
