Crypto tax in Australia, explained simply

"I only sold it for Australian dollars once — surely that's the only bit that counts?" It's one of the most common misunderstandings we see, and an easy one to have, because crypto doesn't feel like a normal investment. It lives on an app, it moves in seconds, and half the time you're swapping one coin for another rather than touching real money at all. But the ATO's view is straightforward once you know it: almost every time you do something with your crypto other than just holding it, that's a taxable event.

The ATO treats crypto as a CGT asset

For most people, cryptocurrency is treated the same way as shares or an investment property — as a capital gains tax (CGT) asset. That means a capital gain or loss can arise whenever you dispose of it, and "dispose of it" covers more ground than most people expect:

• Selling crypto for Australian or foreign dollars
• Swapping one crypto asset for another (yes — even if no cash ever changes hands)
• Using crypto to buy goods or services
• Gifting crypto to someone else

Each of those is its own event, calculated separately, on the date it happened. If you've been actively trading between coins over the past year, that can add up to a lot of individual calculations — which is exactly why record-keeping (below) matters so much.

What records you actually need

The ATO expects you to be able to show, for every transaction:

• The date of the transaction
• What you received and what you gave up
• The value in Australian dollars at the time (not when you lodge your return)
• Which wallet or exchange it happened on
• Any fees paid to the exchange or a software tool

If you're using an exchange that provides an annual tax report, or crypto tax software, that's usually the easiest way to keep this organised — but it's worth checking the report actually covers everything, including transfers between your own wallets (which aren't taxable, but need to be identifiable as such rather than looking like unexplained gaps).

The 12-month discount

If you're an individual (not a company or trust) and you've held a crypto asset for more than 12 months before disposing of it, you can typically discount the taxable gain by 50%. It's one of the more valuable reasons to know your exact purchase dates — the difference between holding for 11 months and 13 months can be significant.

One thing worth flagging: the discount doesn't apply to assets held as "personal use" (broadly, things bought to spend on goods or services rather than as an investment) — and most crypto holdings don't qualify for that exemption anyway, so don't rely on it without checking first.

The bottom line

If you've bought, sold, swapped, or spent crypto this year, there's a decent chance some of it needs to go in your tax return — whether that's a gain to report or a loss you can use to offset other gains. The earlier you pull your transaction history together, the less painful it is to work through.
