As the time to lodge tax returns nears, the Australian Taxation Office (ATO) is warning taxpayers to be on alert for scammers.
Tax commissioner Michael D'Ascenzo says so far this year, there have been 5000 reports of people receiving emails trying to falsely obtain information by pretending to represent ATO, and 3000 reports of attempted phone scams.
"With the end of the financial year approaching and many people expecting refunds, scammers are using this opportunity to pretend to be from the ATO," he said in a statement on Tuesday.
"It is important that the community stays vigilant as scammers are increasing their efforts to make scams appear more genuine and legitimate."
He said people should be cautious of phone calls or emails suggesting that they were due a refund or asking for a transfer of money overseas.
The ATO would never ask for credit cards details or copies of personal information, such as a passport or drivers's licence, in an email.
"Once scammers have your personal information they can steal your identity and commit fraud against you, with potentially serious consequences," the commissioner warned.
"They can lodge false tax returns in your name, transact using your credit card information or take out a loan in your name."
