It's a scam. The caller has an Indian accent. They're pretending to be from ATO. They'll scare you that you have a criminal case about fraud filing of yearly income tac and that the police will arrest you unless you pay the amount they're asking. BE VERY CAREFUL NOT TO GIVE IMPORTANT INFORMATIONS ABOUT YOU!

Yes, confirming what the previous commenter has said. It's the "ATO" and they are trying to pretend that you are being taken to court the next day. Don't give out any information! If you're unsure, contact the ATO directly to confirm

I have had several calls today from this number and when I called them back from the office phone they didn't answer with an Indian accent like they do when they call your mobile.

They ask if you have a lawyer present and are ready to hear the charges that are going to be filed against you for not paying tax.
