Crypto tax in Australia, explained

Crypto runs on the same tax engine as shares, with a few rules of its own that trip people up. The most important one to absorb first is what the ATO treats crypto as, because everything else follows from it. Crypto is not money for tax purposes. It is an asset, and for most people who hold it to make a profit it is a capital gains tax asset, which means a taxable event happens every time you dispose of it, not just when you cash out to dollars.

Crypto is a CGT asset, and disposal is the trigger

Because crypto is a CGT asset, a capital gains event happens whenever you dispose of it, and disposal covers more than selling for cash. You dispose of crypto when you sell it for Australian dollars, when you convert it to another currency, when you use it to buy goods or services, and when you gift it. Each is worked out on the value in Australian dollars at the time. Wrapping a coin into a wrapped version, and unwrapping it again, count too, because you are exchanging one asset for another.

The crypto-to-crypto trap

Here is the rule that catches the most people. Swapping one crypto for another is a taxable disposal of the first coin, even though no dollars change hands. When you trade one token for another, you have disposed of the token you gave up, and its capital gain or loss is worked out on the Australian dollar value of what you received in return. Someone who traded actively between coins across a year can have a long list of taxable events and a real tax bill, without ever having withdrawn a cent to their bank. Treat every swap as a sale, and the year adds up the way the ATO expects.

The personal use exemption is narrow

There is an exemption for personal use assets, and it is worth understanding mainly so you do not rely on it by mistake. A gain can be exempt only where the crypto is a genuine personal use asset and you acquired it for less than $10,000. Personal use means you obtained it and used it within a short time to buy something for personal consumption, judged by what you actually did with it. It does not apply to crypto you hold as an investment, and it does not apply where you convert to dollars or another coin first, or route the payment through a gift card or a payment gateway. For anyone holding crypto to make a profit, the safe assumption is that this exemption does not apply. Losses on personal use assets are disregarded as well, so it does not help on the way down.

Staking, DeFi and NFTs

The income side of crypto, including staking rewards, airdrops of established tokens and DeFi rewards, is covered in the income chapter: those are taxed as income when you receive them, then carry that value as their cost base. On the capital side, decentralised finance is the least settled area. The ATO's view is that many DeFi transactions, including a lot of what is loosely called lending, and adding to or withdrawing from a liquidity pool, are capital gains events, because your beneficial ownership of the coin changes. The outcome depends on how the specific protocol actually works, so DeFi is the part to check against the current ATO guidance or a registered tax agent rather than assume. NFTs are treated like other crypto assets: a capital gains event on disposal for an ordinary holder, or income if you create and sell them as a business.

Lost, stolen or stuck on a collapsed exchange

Crypto that is genuinely lost or stolen can give rise to a capital loss, but only with evidence. You need to show you owned it and that access is gone for good, such as a private key that cannot be recovered, along with records tying the wallet to you. Where an exchange holding your crypto collapses into administration, a capital gains event generally happens when the administration is finalised rather than when the balance simply drops, and you work out the loss then, reduced by any amount you are paid back. As with all capital losses, these can only offset capital gains, not your other income.

The records the ATO already has

Every disposal needs an Australian dollar value, even a coin-to-coin swap where no dollars moved, and the ATO uses published exchange rates for the conversion. Keep the date, the Australian dollar value and the details of each transaction, along with your wallet and exchange records, and export your history regularly rather than trusting it to still be there later. This matters because the ATO is not working blind. Its crypto data-matching program collects information on well over a million people a year from Australian exchanges and checks it against what is reported, and a lot of it is pre-filled into your return. The gap the ATO notices is the one between the swaps you made and the ones you declared.

The bottom line

Treat crypto as a CGT asset, and treat every disposal, including a swap from one coin to another and spending it, as a taxable event valued in dollars at the time. Do not lean on the personal use exemption if you hold crypto as an investment. Take staking and airdrops as income, check DeFi against current ATO guidance, and keep a capital loss for lost or stolen coins only where you can prove it. Above all, keep the records, because the ATO already holds a copy of most of them.

General information only, not tax or financial advice. Crypto rules, especially for DeFi, change and depend on your facts, so check the ATO or a registered tax agent for your situation.
