The ATO will never threaten you with arrest if you don’t pay a debt immediately.
Call your financial institution immediately if you have given your bank or credit card details to a scammer. Most big banks will cover any loss if someone makes an unauthorised transaction on your account, as long as you have protected your client number and passwords.
If you have paid money to a scammer report it to the authorities. If you have been a victim of a cybercrime such as fraud, report it to the Australian Cybercrime Online Reporting Network (ACORN).
If you are ever unsure about a request for information or the validity of an ATO interaction, call the ATO Scam Hotline on 1800 008 540 or visit ato.gov.au/scams.
Report suspicious emails claiming to be from the ATO by forwarding the entire email to ReportEmailFraud@ato.gov.au and then delete the email from your inbox.
