You might think you’re ahead of the game. You bought some crypto, watched it rise, maybe sold a bit or swapped it for something else. Easy. But then tax time rolls around, and you’re stuck wondering what you’re supposed to report.
You’re not alone. A lot of people assume that if they didn’t withdraw money into their bank account, they don’t have to worry about tax. But in 2025, that assumption could cost you.
The ATO is paying attention. If you’re using crypto and not reporting the right things, it’s not a matter of if they’ll find out. It’s a matter of when.
Do you know when you’re triggering a tax event?
Here’s what catches most people off guard. You don’t have to cash out to Australian dollars to trigger a Capital Gains Tax (CGT) event. Selling crypto? That counts. Swapping one type for another? That counts too. Even giving it to someone else can be a CGT event.
If the value of your crypto changed between when you got it and when you got rid of it, the ATO wants that reported. That difference is a capital gain or loss, and it needs to go on your tax return.
This applies whether you’ve made two trades or two hundred. The rules are the same.
Still think it doesn’t apply to you?
Let’s say you bought a crypto asset for a few hundred dollars. Months later, you trade it for another one. At the time of the trade, it’s worth a lot more than what you paid for it. You didn’t cash it out. You didn’t spend it. Just swapped one asset for another.
That swap is still a disposal. And the value difference? That’s a capital gain.
Even if you lost money, it still matters. Recording capital losses can reduce the tax you pay on future gains. But you can’t claim them if you haven’t recorded them.
What if you’ve received crypto instead of buying it?
If someone gave you crypto as a gift, paid you with it, or rewarded you for something, that’s usually considered income. It’s counted at the value on the day you received it.
And once you decide to sell or swap it later, that triggers a CGT event. The same asset could end up being reported twice in two separate ways.
Missing any of these steps could throw off your whole tax return. Worse still, it might trigger questions from the ATO.
Think the ATO isn’t watching?
That would’ve been an easier mistake to make a few years ago. But now? The ATO has access to data from Australian and overseas exchanges. They can see who’s trading and when.
If there’s a gap between what they see and what you report, your return could be flagged. Sometimes it’s just a letter. Other times, it’s a formal review.
And if it turns out you’ve left something out, even by accident, you could be looking at penalties or interest on top of what you already owe.
The price of poor records
Not keeping proper records doesn’t just make your life harder. It can lead to overpaying tax.
If you can’t prove how much you paid for your crypto, the ATO might assume your full sale price was profit. That means more tax than you actually owe.
You should be tracking every transaction. That includes:
- The date you bought or sold
- How much it was worth in Australian dollars at the time
- Any transaction fees
- Who you bought from or sold to
- What the purpose of the transaction was
This isn’t just about staying compliant. It’s also about protecting yourself from being taxed unfairly.
What if you’ve already made a mistake?
Don’t panic. It’s fixable. If you missed something in a previous return, you can update it. It’s better to make the correction yourself than to wait for the ATO to come looking.
Fixing it now shows that you’re taking responsibility. That can make a big difference if there are penalties involved.
So what should you do next?
Start by getting your records in order. Most platforms let you download your trading history. From there, you can calculate your gains and losses, work out what’s income, and make sure you’re reporting everything correctly.
If you’re not confident doing it yourself, get help from a registered tax agent who understands crypto. They can make sure you’re not missing anything or paying more than you should.
One final thought
Crypto might still feel like new territory, but the tax rules are already in place. The ATO isn’t waiting for the industry to catch up. They expect you to get it right now.
So ask yourself:
- Have I reported every time I got rid of a crypto asset?
- Did I account for any assets I received as income?
- Are my records complete and accurate?
If you’re not sure, then you probably have work to do.
The sooner you sort it out, the better. Because when tax time hits, “I didn’t know” won’t be a good enough excuse.
