How Is Cryptocurrency Taxed in Australia? Your Complete Guide to CGT on Crypto
Quick answer first, because this is the part most people actually need: yes, the ATO treats cryptocurrency as a capital gains tax (CGT) asset for most Australians who hold it as an investment, which means selling it, swapping it for another coin, spending it, or even giving it away can all trigger a taxable event — not just cashing out to Australian dollars. If you did anything with Bitcoin, Ethereum or any other digital asset during the 2025–26 income year besides simply holding it, there's a real chance you need to report a capital gain or loss on the return you're racing to finish before 31 October 2026.
We hear a version of the same sentence from new clients almost every tax season: ‘I never actually took any money out, so it's not taxable, right?’ It's one of the most common — and most expensive — misunderstandings in Australian crypto tax, and the ATO is well aware it happens constantly. That's exactly why they run a data-matching program built specifically around crypto exchanges, which we'll get to further down.
This guide walks through how crypto CGT actually works here: what counts as a taxable event, how to work out your cost base, when the 50% CGT discount applies, why staking rewards and airdrops are taxed completely differently to capital gains, the surprisingly narrow personal use exemption, and exactly what records the ATO expects you to keep. We've also broken down which financial year's transactions belong on this return, because September is exactly when that gets confusing.

What Counts as a Taxable Crypto Event in Australia?
Here's the direct answer: according to the ATO, a CGT event happens the moment you sell a crypto asset, gift it to someone else, trade or swap it for a different crypto asset, convert it into Australian or foreign currency, or use it to buy goods or services. Every one of those five actions is a disposal, and a disposal is what triggers the calculation — not the moment you eventually see AUD land in your bank account.
• Selling a crypto asset for AUD (the obvious one)
• Gifting crypto to a partner, friend or family member — yes, even as a gift
• Trading, exchanging or swapping one crypto asset for another crypto asset — this is the one that catches people out
• Converting crypto into Australian dollars or any foreign currency
• Using crypto to pay for goods or services, from a coffee to a car
One thing worth flagging early: this guide is written for individuals holding crypto as a personal investment, which is how the overwhelming majority of our clients hold it. If you're running a business that mines crypto, trades it as a business activity, or accepts it as payment for goods and services you sell, different rules apply under trading stock and ordinary income provisions rather than the CGT rules covered here — that's a conversation worth having with your accountant directly, since it changes the numbers substantially.
How the ATO Calculates Your Crypto Capital Gain
The formula itself isn't complicated: your capital gain is what you received for disposing of the asset (the capital proceeds) minus what it cost you to acquire it (the cost base). Add up every gain for the year, subtract any capital losses, then apply the CGT discount you're entitled to, and what's left is your net capital gain — the figure that actually gets added to your taxable income.
The cost base isn't just the purchase price. It includes the AUD value you paid at the time you acquired the asset, plus incidental costs like exchange fees, brokerage and transfer fees. And this is where crypto gets genuinely fiddly compared to, say, shares: every single transaction needs to be converted to its Australian dollar value at the time it happened, using the exchange rate on that specific date — not the rate on 30 June, and not the rate on the day you sit down to do your tax return. If you've made even a moderate number of trades across a couple of exchanges, doing this by hand in a spreadsheet gets old fast, which is why most active traders end up using dedicated crypto tax software to reconstruct the AUD value of every transaction.
Capital losses are useful, but only within limits. They can offset capital gains from crypto, shares, property or any other CGT asset, either in the same year or carried forward indefinitely into future years — but they can't be used to reduce your salary or wages income. So if your only crypto activity in 2025–26 was a loss, it doesn't get you a bigger refund on its own; it sits there and waits to offset a future gain.
The 50% CGT Discount: Do You Qualify?
If you're an Australian resident individual and you held the crypto asset for at least 12 months before disposing of it, you may be able to reduce your assessable capital gain by 50%. Note the word ‘may’ — it's not automatic, and it doesn't apply to everyone or every structure. Companies, for instance, don't get access to the discount at all, and trusts have their own separate rules.
The practical catch for crypto investors specifically is parcel-level tracking. Most exchanges will happily show you an ‘average cost’ across all your holdings of a particular coin, but the ATO wants to know the acquisition date and cost base of the specific units you disposed of — because whether any given disposal qualifies for the discount depends on how long that specific parcel was held, not how long you've been generally ‘in’ Bitcoin as an asset class. If you bought Bitcoin in three separate purchases over 18 months and then sold half your holding, which half you're treated as selling can genuinely change your tax bill. This is exactly why the record-keeping section further down matters as much as it does.
The Crypto-to-Crypto Trap Almost Everyone Falls Into
This is worth its own section because it's the single biggest source of unpleasant surprises we see. A lot of people assume that swapping Ethereum for Solana, or trading one token for another on a decentralised exchange, isn't a taxable event because Australian dollars were never involved. The ATO disagrees, explicitly and in writing: trading, exchanging or swapping one crypto asset for another is listed as a disposal that triggers a CGT event, on exactly the same footing as selling for cash.
What makes this genuinely painful in practice is that it can create a tax bill on an asset you never actually converted to cash — and one that doesn't go away even if the new asset you swapped into later crashes. Say you swap $20,000 worth of one token for a different token, and that trade locks in a $6,000 gain at the moment it happens. If the new token then drops 80% in value before you ever sell it, you've still crystallised that $6,000 gain in the eyes of the ATO; the later loss is a separate, later CGT event on the new asset, not something that cancels out the first one retroactively. Active traders who do a lot of swapping between coins are the group most likely to get caught by this, and it's specifically named by the ATO as one of the common mistakes it sees at tax time.
Staking Rewards, Airdrops and Mining: A Different Set of Rules
Capital gains tax isn't the only tax that applies to crypto — and this is where the two-step nature of crypto tax trips a lot of people up. Staking rewards, airdrops and mining rewards are generally treated as ordinary income, not capital gains, and they're taxed at the market value (in AUD) of the crypto at the moment you receive it. That value gets reported as assessable income — commonly under ‘other income’ — in the same way interest from a savings account would be.
Then there's a second step, and it's easy to forget. Once you eventually sell, swap or spend that staking reward or airdropped token, a separate CGT event happens on any change in value since you received it. The cost base for that second calculation is whatever AUD value you already declared as income — so you're not taxed twice on the same dollar, but you do need to track both events separately. Forgetting to declare airdrop or staking income in the first place is specifically flagged by the ATO as one of the recurring mistakes it identifies through its compliance work.
Is Your Crypto a “Personal Use Asset”? The $10,000 Exemption
There is a genuine exemption here, but it's much narrower than people assume. A capital gain on crypto can be exempt from CGT if the asset qualifies as a personal use asset and was acquired for less than $10,000. To qualify, you need to have kept or used the crypto mainly for personal use — for example, buying it specifically to purchase goods or services for yourself, and then using it that way relatively soon after acquiring it.
The test is genuinely about how you used the asset, not what you originally intended. The ATO's own example is buying concert tickets with crypto you bought that same day for that purpose — that's personal use. What doesn't qualify is holding crypto as an investment, hoping it goes up in value, and then later deciding to spend some of it on a personal purchase. Using investment gains to buy something for yourself doesn't retroactively turn an investment asset into a personal use asset. For most of our clients — people who bought crypto as an investment and held it for months or years before doing anything with it — this exemption simply doesn't apply, even on smaller holdings, which is a misconception worth clearing up early.
2025–26 vs 2026–27: Which Year's Transactions Go on This Return?
Right now, in September 2026, we're sitting in the first quarter of the 2026–27 financial year — but the tax return most people are trying to get finished before 31 October 2026 covers the 2025–26 income year, meaning transactions between 1 July 2025 and 30 June 2026. Every crypto disposal that happened inside that window — a sale, a swap, a purchase made with crypto — belongs on this year's return, and needs to be valued using the AUD exchange rate on the actual date of each transaction, not today's exchange rate.
Anything you've bought, sold or swapped from 1 July 2026 onward falls into the 2026–27 income year instead, and won't need to be reported until you lodge next year's return. That doesn't mean it's fine to stop tracking it now — quite the opposite, since untracked transactions are exactly how people end up scrambling through twelve months of exchange history next September. The good news is that the underlying CGT mechanics — the cost base method, the 50% discount, the personal use exemption threshold — haven't changed between the two years; the ATO's core crypto CGT guidance was last updated on 22 June 2026, and the fundamentals are consistent with what applied in 2025–26. What changes each year is simply which transactions belong on which return, and mixing that up is a genuinely common way to under-report or over-report a gain.
How the ATO Actually Tracks Your Crypto
This isn't a scare tactic — it's public ATO policy. The ATO has confirmed it can track transactions back to individual taxpayers using data obtained from banks, financial institutions and crypto asset exchanges, and it actively cross-references that data against what people declare on their tax returns. Australian-based exchanges, and a good number operating here from overseas, report customer transaction data to the ATO as a matter of course.
In practical terms, that means ‘I'll just leave it off’ isn't a strategy — it's a bet that the ATO's data-matching program won't catch a specific transaction, and it's a bet with worse odds every year as the program matures. If you've under-reported crypto income or gains in a previous return, the far better move is a voluntary disclosure to a registered tax agent sooner rather than later, since the ATO treats voluntary corrections noticeably more leniently than discrepancies it finds itself.
Record-Keeping: What to Keep and For How Long
The ATO expects you to keep crypto records for five years from whichever is latest: the date you prepared or obtained the records, the date the transactions were completed, or the date of the relevant CGT event. If a loss you claimed this year is only used to offset a gain three years from now, the clock effectively resets around that later event too — so ‘five years and I can delete everything’ is a rougher rule of thumb than it sounds.
What you actually need to keep: the date of each transaction, its AUD value at the time, the purpose of the transaction, and details of the other party (even if that's just a wallet address), plus receipts, exchange statements and wallet records. If you've paid for tax agent fees, crypto tax software or legal advice related to managing your crypto tax affairs, keep those receipts too — they're generally deductible.
Our practical advice, based on how often this goes wrong: export full transaction history CSVs from every exchange and wallet you've used at least once a year, and store them somewhere outside that exchange's own platform. Exchanges shut down, get acquired, or simply purge old account history, and ‘I'll download it later’ is how people end up trying to reconstruct three years of trading activity from memory.
A Worked Example: Calculating Crypto CGT Step by Step
Numbers make this concrete, so here's a simplified example using round figures.
• Purchase: 1 BTC bought in August 2024 for $40,000 AUD, plus a $50 exchange fee — cost base of $40,050.
• Sale: the same 1 BTC sold in September 2025 for $65,000 AUD.
• Holding period: just over 12 months, and the investor is an Australian resident individual — eligible for the 50% CGT discount.
• Capital gain before discount: $65,000 − $40,050 = $24,950.
• After the 50% discount: $12,475 is added to assessable income for the 2025–26 return.
Now say the same investor also swapped 0.5 ETH for SOL in the same income year. That 0.5 ETH was bought four months earlier for $2,400, and was worth $3,000 AUD at the moment of the swap. Held for under 12 months, so no discount applies — the full $600 gain is added to assessable income.
Total net capital gain for the 2025–26 return: $12,475 + $600 = $13,075 added to taxable income, from two separate CGT events with two completely different discount outcomes. That's the level of detail the ATO expects for each disposal — which is exactly why lot-level records matter more than a single ‘portfolio value’ number from an exchange dashboard.
What Happens If You Don't Report Crypto Gains?
Given the data-matching point above, this isn't a hypothetical risk. When a discrepancy is flagged, it can lead to an amended assessment, the general interest charge (GIC) accruing on any unpaid tax, and potentially penalties for false or misleading statements. How much that penalty is depends heavily on culpability — an honest, reasonable mistake is treated very differently to recklessness or a deliberate attempt to under-report — and it's assessed case by case rather than on a fixed scale.
If you think a previous return may have missed crypto income or gains, the practical move is to speak with a registered tax agent about a voluntary disclosure before the ATO's own review process picks it up. Getting ahead of it is consistently the better outcome, both financially and in terms of stress.
Frequently Asked Questions
Do I have to pay tax on crypto I haven't sold yet?
No. Simply holding a crypto asset isn't a taxable event on its own — a CGT event only happens when you dispose of it in one of the ways covered above, such as selling, swapping, spending or gifting it.
Is buying crypto with Australian dollars a taxable event?
No, acquiring crypto isn't itself a CGT event. But the AUD amount you pay, plus any fees, becomes the cost base you'll use to calculate your gain or loss whenever you eventually dispose of it.
Do I pay CGT if I move crypto between my own wallets or exchange accounts?
No. Transferring crypto that you own between your own wallets, or between your own accounts on different exchanges, isn't a disposal — provided you can show you remained the beneficial owner of the asset the whole time. Keep records of these transfers anyway, since they help explain gaps in your exchange history.
What if I made a loss on crypto rather than a gain?
Capital losses can be offset against capital gains from crypto, shares, property or other CGT assets — either in the same income year or carried forward to future years — but they can't be used to reduce your salary or wages income.
Do these same rules apply to NFTs?
Generally, yes. The ATO's crypto asset guidance extends to NFTs as a type of digital asset, and they're typically subject to the same CGT framework covered in this guide, though valuing an NFT accurately can be more complicated given how few of them have an active, liquid market price.
