It is more important than ever to protect your personal information such as tax file numbers, your date of birth, current address and myGov and internet banking details to name a few.
With this information scammers have been organising loans from banks in other peoples names, and making calls purporting to be from the ATO in order to scare unsuspecting taxpayers into paying debts that do not exist.
If you are unsure you are receiving a genuine call from a government authority and not a scam artist, state that you will call back, ensuring that you verify the contact number yourself.
If you have a registered tax agent they can deal with the ATO on your behalf.
