When you sell Bitcoin, trade Ethereum for Solana, or even use crypto to buy coffee in Australia, the taxman is watching. The Australian Taxation Office (ATO) doesn’t treat crypto like cash. It treats it like property. That means every time you dispose of it - whether you sell, trade, spend, or gift it - you might owe capital gains tax (CGT). And if you don’t track it properly, you could end up paying way more than you need to.
What counts as a taxable event?
You don’t need to cash out to trigger tax. Any time you get rid of crypto, it’s a CGT event. That includes:- Selling crypto for Australian dollars
- Trading one crypto for another (like BTC for ETH)
- Using crypto to buy goods or services
- Gifting crypto to someone who isn’t your spouse
- Paying transaction fees in crypto (yes, even the network fee on a transfer counts)
Each of these actions creates a taxable gain or loss. The ATO requires you to calculate the value in Australian dollars at the exact moment the transaction happens. No estimates. No guesses. You need the price from a reputable exchange at the time of the trade.
How the 50% CGT discount works
This is the biggest lever in Australia’s crypto tax system. If you hold your crypto for more than 12 months before selling or trading it, you get a 50% discount on your capital gain. That means only half the profit is added to your taxable income.Let’s say you bought 0.5 BTC for $15,000 in January 2024. In March 2025, you sell it for $30,000. Your capital gain is $15,000. Because you held it over 12 months, you apply the discount: $15,000 × 50% = $7,500. That $7,500 is what gets added to your income.
Now, if you’d sold it in November 2024 - just one month short of the 12-month mark - you’d pay tax on the full $15,000. For someone in the 37% tax bracket (income between $90,000 and $180,000), that’s a difference of $2,775 in tax owed. Waiting 45 more days saves you thousands.
That’s why so many Australian crypto investors time their sales. A University of Sydney survey in January 2025 found 78% of holders deliberately waited over a year to qualify for the discount.
What if you’re an active trader?
The ATO draws a line between investors and traders. Investors buy and hold. Traders buy and sell frequently - often daily or weekly. If you’re trading crypto like a business, the ATO may treat all your gains as ordinary income, not capital gains. That means you lose the 50% discount entirely.There’s no hard rule like “100 trades per year = trader.” But the ATO looks at patterns: frequency, volume, intent, and whether you’re using trading strategies like day trading or arbitrage. If you’re spending hours analyzing charts, using leverage, or treating crypto like a job, you’re at risk of being classified as a trader.
One 2024 AAT case (Commissioner of Taxation v Bitcoin Trader) confirmed that frequent, systematic trading can be classified as carrying on a business. The taxpayer lost the CGT discount and owed tax on the full amount of gains at their marginal rate.
For active traders, the tax burden can be brutal. Without the discount, a $20,000 gain could mean an extra $8,000 in tax if you’re in the top bracket. Many traders end up paying more than 45% in total tax - including the 2% Medicare levy.
Cost base and record keeping: the silent killer
Your capital gain isn’t just the sale price minus the buy price. You need to include all costs: exchange fees, withdrawal fees, and even the value of crypto used to pay network fees.Example: You buy 1 ETH for $3,000 and pay a $10 gas fee in ETH. That $10 worth of ETH is a separate CGT event. You must calculate the cost base of that ETH at the time you used it. If that ETH was bought for $8, then you have a $2 gain on the gas fee alone. That $2 gets added to your overall capital gain.
Most people don’t realize this. A CoinLedger survey of 200 Australian crypto users in April 2025 found that 42% struggled with calculating cost bases correctly - especially for assets acquired through airdrops, mining, or staking.
The ATO requires you to keep records for five years. That includes:
- Date and time of each transaction
- Value in AUD at the time
- What you received and what you gave up
- Exchange records and wallet addresses
- Receipts for fees paid
Doing this manually takes 15-20 hours per year. Most users turn to software. Koinly, CoinTracker, and CryptoTaxCalculator are the most popular. A ProductReview.com study in March 2025 showed 67% of users found these tools more accurate than the ATO’s free calculator.
What doesn’t get taxed?
There are two narrow exemptions:- Personal use asset: If you buy crypto to use it personally - like buying a laptop with BTC - and the value is under $10,000 AUD, it’s exempt. But this only applies if you bought it to use, not to invest. If you bought BTC at $20,000, held it for a year, then used it to buy a $9,000 laptop, you still owe tax on the $11,000 gain. The $10,000 exemption doesn’t apply to the gain - only to the original purchase if it was purely for personal use.
- Capital losses: If you lose money on crypto, you can use it to offset gains. Say you bought an NFT for $5,000 and sold it for $1,000. That $4,000 loss can be used to reduce gains from your Bitcoin sale. Losses can be carried forward indefinitely. One CoinTracker case study showed an investor used $35,000 in NFT losses to wipe out their crypto gains entirely.
How Australia compares to the world
Australia’s system is simpler than the U.S. - no separate long-term tax brackets - but harsher for high earners. In the U.S., long-term gains are taxed at 0%, 15%, or 20% depending on income. In Australia, even with the 50% discount, your gain gets added to your regular income and taxed at your marginal rate - up to 45% plus 2% Medicare levy.Compare that to Portugal, where individuals pay zero capital gains tax on crypto. Or Singapore, where long-term holdings are tax-free. Or Germany, where crypto held over a year is completely tax-exempt. Australia’s 50% discount is generous - but only if you’re patient. For active traders, it’s one of the toughest systems in the developed world.
What’s changing in 2025 and beyond?
The ATO is getting smarter. In February 2025, it started direct data sharing with major Australian exchanges like Swyftx, CoinSpot, and Independent Reserve. That means they now have your buy/sell history - even if you didn’t report it.By 2026, the Digital Asset Data Exchange will connect even more platforms. KPMG predicts compliance rates will jump from 65% to over 85% by then. The ATO’s 2025-26 compliance program specifically targets traders with over 100 transactions a year.
Staking rewards and DeFi income are still gray areas. The ATO has confirmed staking rewards are assessable income - you pay tax when you receive them. But how to value them? What about liquidity provision in Uniswap? The ATO hasn’t clarified yet. PwC expects guidance by 2026.
For now, the 50% discount is safe. EY’s tax policy leader Jane Kelly said in June 2025: “It’s politically popular. No government will touch it.” But the rules around what counts as a disposal? That’s where the real risk lies.
What to do now
If you own crypto in Australia, here’s your action plan:- Use crypto tax software. Don’t rely on spreadsheets. Koinly, CoinTracker, or CryptoTaxCalculator will auto-import your transactions and calculate your gains/losses.
- Track every single transaction - even small ones. That $5 ETH gas fee? It matters.
- Hold for at least 12 months before selling. The discount is your biggest tax saver.
- Don’t assume small purchases are exempt. The personal use rule is narrow and easy to misapply.
- Use losses to offset gains. If you’ve lost money on any asset, don’t ignore it.
- Keep records for five years. The ATO can audit you anytime within that window.
The system isn’t perfect. It was built for stocks and property, not for 24/7 digital markets. But it’s the law. And for those who plan ahead, it’s manageable - even advantageous.
Do I pay tax on crypto I hold but don’t sell?
No. You only pay tax when you dispose of crypto - meaning you sell it, trade it, spend it, or gift it. Holding crypto, even if its value goes up, doesn’t trigger tax. The tax event happens at the point of disposal.
Are airdrops and staking rewards taxable?
Yes. Both airdrops and staking rewards are treated as ordinary income. You pay tax on the Australian dollar value of the crypto when you receive it. This is separate from capital gains tax. For example, if you earn 0.5 ETH in staking rewards worth $1,200, you pay income tax on $1,200. Later, if you sell that ETH, you’ll also pay capital gains tax on any increase in value from the time you received it.
Can I use losses from one crypto to offset gains from another?
Yes. All crypto assets are treated as separate CGT assets, but capital losses from any crypto can be used to offset capital gains from any other crypto. For example, if you lost $3,000 on Solana but made $8,000 on Bitcoin, you can reduce your taxable gain to $5,000. Losses can be carried forward to future years if you don’t have gains in the current year.
What happens if I transfer crypto between my own wallets?
Nothing. Transferring crypto between wallets you own - even across exchanges - is not a taxable event. The ATO only sees disposal when you give up control to someone else. So moving BTC from Coinbase to your Ledger doesn’t trigger tax. But if you send it to a friend’s wallet, that’s a gift - and that’s a taxable disposal.
Is there a tax-free threshold for crypto gains?
Yes. The $18,200 tax-free threshold applies to crypto gains just like any other income. If your total taxable income - including crypto gains - is under $18,200 in a financial year, you pay no income tax. But if your crypto gain alone pushes you over that amount, you’ll pay tax on the portion above $18,200. The threshold doesn’t mean your first $18,200 of crypto gain is free - it’s your total income that matters.
Can I claim a loss if I lose access to my crypto (e.g., lost seed phrase)?
Generally, no. The ATO doesn’t allow deductions for lost, stolen, or inaccessible crypto unless you can prove it was stolen or hacked and you reported it to police. Losing your private key or forgetting your password doesn’t count as a capital loss. You need evidence - like a police report or exchange confirmation of a hack - to claim it. Most losses from forgotten passwords are not deductible.
