Scammers taking advantage of tax time are trying to trick Australians into handing over their personal details with the promise of a tax refund through a fake myGov form.

Stay Safe Online issued a high alert for the latest scam on Wednesday.

The phishing email claims to come from myGov and has the subject line, "Important information regarding your account", as well as the myGov logo.

It asks you to click on a link to claim your refund, which leads to a fake tax refund claim form, asking for personal details such as email, password, and credit card information.

Australian Taxation Office assistant commissioner Kath Anderson said tax time was popular for scammers to prey on unsuspecting Australians.
