Does CoinJar Report to the ATO?

Using CoinJar to trade crypto in Australia? The ATO probably knows already. Find out what information CoinJar shares with the ATO and how it impacts you.

  • CoinJar, like other Australian crypto platforms, participates in the ATO’s data-matching initiative.

  • As a registered AUSTRAC provider, CoinJar is required to verify your identity and may provide that data to the ATO.

  • Details such as your name, contact info, wallet addresses, transaction history, and trade amounts could be reported.

Does CoinJar report to the ATO?

Yes, CoinJar may share information with the ATO. As a registered Digital Currency Exchange (DCE) with AUSTRAC, CoinJar is obligated to verify user identities (KYC) to combat fraud and illegal activity.

The ATO has operated a data-sharing program since 2019 with Australian crypto exchanges. As part of this program, platforms like CoinJar are required to submit user transaction data.

In some cases, this information may appear prefilled in your tax return, flagging crypto disposals and prompting you to review potential taxable events.

What does the ATO do with the information CoinJar provides?

The ATO leverages data from platforms like CoinJar to ensure Australians are correctly reporting their cryptocurrency activity. This data may be used to:

  • Identify people who are expected to include crypto in their tax returns

  • Trigger reminders or prompts during online tax return lodgment about crypto reporting obligations

  • Cross-reference tax return details with transaction data provided by CoinJar and other exchanges

How do I report my CoinJar taxes to the ATO?

If you trade or earn crypto through CoinJar, you’re required to report any capital gains, losses, or income to the ATO by October 31st each year as part of your annual tax return.

Capital gains and losses are reported using the Tax Return for Individuals – Supplementary Section (NAT 2679), while crypto-related income goes in the standard Tax Return for Individuals (NAT 2541). You can also lodge your return through the ATO’s online myTax portal.

CoinJar doesn’t issue dedicated tax forms for Australian users, so the easiest way to handle your tax reporting is by using a crypto tax calculator like Koinly.
