What Events Trigger Crypto CGT in Australia?
Per the ATO, a CGT event occurs when you:
- Sell cryptocurrency for Australian dollars or other fiat currency
- Trade one cryptocurrency for another (e.g. BTC → ETH)
- Use cryptocurrency to purchase goods or services
- Receive cryptocurrency through an airdrop or fork (in some circumstances)
- Transfer crypto to a DeFi protocol in exchange for a different token
- Receive staking rewards (generally treated as income, not CGT)
Simply holding cryptocurrency, moving it between your own wallets, or receiving it as a gift does not trigger CGT — though it may affect your cost base.
How to Calculate Crypto CGT
Your capital gain or loss is: Sale proceeds minus cost base. The cost base is what you paid for the crypto (in AUD) at the time of acquisition, including exchange fees. For crypto-to-crypto trades, the "proceeds" is the AUD market value of the crypto you received at the time of the trade. This requires you to know the AUD price of every asset at every point of acquisition and disposal — often thousands of transactions for active traders.
The 12-Month Discount Applies to Crypto
The 50% CGT discount applies to cryptocurrency held for more than 12 months before disposal, just like shares and property. This is one of the most significant tax advantages available to long-term crypto holders. Bitcoin purchased in January 2025 and sold in February 2026 (14 months later) at a profit qualifies for the 50% discount — only half the gain is taxable. The 12-month clock restarts on every crypto-to-crypto swap.
ATO Compliance — The Data Matching Program
The ATO has formal data sharing agreements with all major Australian cryptocurrency exchanges including CoinSpot, Swyftx, BTC Markets, Binance Australia and others. The ATO receives transaction data from these exchanges and cross-references it against tax returns. Not reporting crypto CGT is extremely high risk — the ATO sends approximately 400,000 crypto-related "nudge letters" to taxpayers each year. If you receive one, you have 28 days to amend prior-year returns without penalty before the ATO commences an audit.
Record Keeping for Crypto Tax
The ATO requires you to keep records of:
- The date of every acquisition and disposal
- The AUD value at time of acquisition and disposal (market price)
- What the transaction was for (trade, purchase, airdrop, staking)
- Exchange records and wallet addresses
For active traders with thousands of transactions, dedicated crypto tax software (Koinly, CoinTracker, CryptoTaxCalculator.io) pulls data from exchanges via API and calculates your CGT automatically. These typically cost $50-$300/year depending on transaction volume.
Frequently Asked Questions
Do I pay tax on cryptocurrency in Australia?
Yes. The ATO treats cryptocurrency as a CGT asset. Every disposal (sale, trade, spend) creates a CGT event. The 50% discount applies if held over 12 months. Staking and mining rewards are generally taxed as ordinary income at the AUD value when received.
Is crypto-to-crypto trading taxable in Australia?
Yes. Swapping one cryptocurrency for another is treated as a disposal of the first asset and acquisition of the second. This triggers CGT on the first asset based on its AUD market value at the time of the swap, regardless of whether you received any AUD.
What happens if I lose money on crypto in Australia?
Capital losses can be offset against capital gains from other assets (shares, property) in the same year, reducing your overall CGT. Excess losses carry forward indefinitely. Losses cannot be offset against ordinary income like salary.
