If it sounds like a rat, smells like a rat, and acts like a rat it most likley is a rat.
Don't be fooled please people.
I got the call today and can confirm the ATO do not ask for this info over the phone.

it is wired, the lady call my number by anonymous phone- without caller ID, is the ATO doing things like that? so i believe it is a scam.

"Early" collections ? Please wait until the debt is overdue before calling. Don't call early. Thanks

This number called me & wanted my bank account details to confirm my identity!! Apparently they couldn't identify me any other way.. yeah right. I said I'm sure they will call me again if the ATO needs me that urgently & the lady just said ok & hung up. Might drag it on a lot longer next time just to annoy them!!!!!

Don't give out any personal information.
This is a scam.

SCAM! SCAM! SCAM!

It may sound legit, but it's not. Just a good scam out to trick you. Be warned!

Definitely a scam; just called Australian Taxation Office and they have no record of this number. The lady who called insisted on my personal and company information before she would tell me what the call was regarding. Got very cross when I asked for her particulars so that I could check that she was from the ATO. Number was showing as "number withheld". Worrying part was that she knew who my Accountant was and our Trust name. Started threatening that if they didn't get information and if I didn't call back within two days they would prosecute. Be careful.

Yup, the number is genuine. I did not feel comfortable to talk to the lady when she rang me as she was very rude and sounded like one of the sham calls from overseas. So i rang the ATO myself and sorted things out.

I have been working with the ATO for some time and I can confirm that this is not a scam number.
It is for the Early Intervention Area of the ATO but once again, if in doubt, call the ATO directly on their general line.

But you need to provide your tax agent number...... you have completely different proof of identity protocols that you follow, idiot

I have had ongoing dealings with the ATO about my business affairs.
I can confirm this number is real.

It's listed on the ATO website as on of their contact numbers...

Have a look on the "phone us" ATO web page. This number is there under Debt Early Intervention.

This is a legitimate number. It is on the ATO site. see here: https://www.ato.gov.au/about-ato/about-us/contact-us/phone-us/
Scroll down to the section headed "Business-hours services" and look in the bottom row.

This number is the ATO Early Intervention number as listed on their website: https://www.ato.gov.au/about-ato/about-us/contact-us/phone-us/

That is true. I just called the ATO and they confirmed it for me

It is a legitimate ATO number from Early Debt Collection. It's listed on the ATO website here: https://www.ato.gov.au/About-ATO/About-us/Contact-us/Phone-us/

I received a voicemail with this number and assumed it was a fraud, but called the ATO and it really was them.

RD ... this is not a scam .. YOU ARE COMPLETELY WRONG!! This is the ATO Early Intervention number - you've just wasted my time, checking it all out. You obviously don't know your arse from a pungent curry ...

This is a scam - do not provide your personal tax file number - they asked me to contact them regarding a company I dealt with 8 years ago - This is scary that they would have my details when I never dealt with the Tax office for this company

This phone number is listed on the ATO website for their Debt Early Intervention department. See link: https://www.ato.gov.au/About-ATO/About-us/Contact-us/Phone-us/

This is correct. You don't need to give any information other than your name. Ask the call centre staff to tell you a detail that a scammer would not know. For example, what was they last payment amount you made and how was it made? When did you lodge your last return? Was there a debt or refund? How much?
If your still feeling uncertain hang up but this should be easy to answer for the ATO. It is good practice with any provider such as telephone company banks etc.
