Be aware of this number.
Guy calls and sais he is from ATO and demands that you pay an outstanding TAX or it will be passed on onto fraud department and your business will be restricted and you will have to go to court. First I freaked out as my accountant pays my Tax bills and I thought what if he never did and now I have to go to court but then you ask him to forward the paperwork or at least an email with the outstanding invoice when he gets really rude and demanding. Quote "Asking you what you need a piece of paper for? Stick it up our ass?" On that note I got to my senses and realised that it was a fraud lol.
Anyhow just look out for this one lol

A 'wicemail' (voicemail) message left, calmly insisting that I call back to discuss the lawsuit otherwise caller would be forced to issue have an arrest warrant issued with local authorities.

Told me to immediately call back on number provided as i have tax debt and if i dont they will issue a warrant for my arrest

Message from caller said that there was a law suit against me and he was going to issue an arrest warrant and lodge it with the local court in Darwin if I didn't call back. This is ridiculous, not calling back.

scam claiming to be the Australian tax office
