  • extra attachments or information – the only accepted attachment will be the completed CGT crypto information form

If you choose to communicate with the ATO via email, be aware that the internet is not a secure environment, and we cannot guarantee the privacy and security of personal information.

We don't respond to this mailbox. If you have any questions, phone 13 28 61.

What happens if you don't respond

If you choose not to respond, we may:

  • take further compliance action, such as an audit, which could result in additional costs to you
  • estimate your net assessable amount or taxable income.

If we find you owe us tax, we may apply a penalty of at least 75% on that amount. This means an extra $750 for every $1,000 you owe.
