The Australian Tax Office (ATO) treats cryptocurrency as property, not currency. This means most crypto transactions are subject to capital gains tax (CGT).
Key Rules
| Rule | Detail |
|---|---|
| Tax treatment | Property (CGT asset) |
| CGT discount | 50% discount if held > 12 months |
| Tax-free threshold | Personal use asset exemption (small transactions) |
| Staking | Taxed as income when received |
| Crypto-to-crypto | Taxable event (disposal) |
| Reporting | Tax return via MyGov |
When CGT Applies
You trigger a CGT event when you:
- Sell crypto for fiat (AUD)
- Trade crypto for another crypto
- Use crypto to buy goods or services
- Gift crypto (to non-charity)
- Airdrop or hard fork (receiving new coins)
The 12-Month CGT Discount
If you hold crypto for more than 12 months, you get a 50% discount on the capital gain. This applies to individuals only (not companies).
Example: You buy $10,000 of ETH, sell for $20,000 after 14 months.
- Gain: $10,000
- After 50% discount: $5,000 taxable gain
- At 37% marginal rate: $1,850 tax (instead of $3,700)
Personal Use Asset Exemption
Crypto used to buy personal items under $10,000 is exempt from CGT. This applies if:
- You used crypto directly (not sold for AUD first)
- The item is for personal use
- The transaction is under $10,000
Staking, Lending, and DeFi
| Activity | Tax Treatment |
|---|---|
| Staking rewards | Income when received (market value in AUD) |
| Lending interest | Income when received |
| Airdrops | Income when received (unless unexpected) |
| DeFi yield | Income when received |
| Mining | Business income (or hobby income) |
Cost Basis Rules
Australia uses the first-in, first-out (FIFO) method by default. You must track:
- Date of acquisition
- Cost in AUD (including fees)
- Date of disposal
- Proceeds in AUD
ATO Data Matching
The ATO has a robust crypto data matching program. They collect data from exchanges and compare it to your tax return. The ATO can see:
- Your identity (via Know Your Customer data)
- Transaction history
- Deposits and withdrawals
Assume the ATO knows about your crypto activity.
Record Keeping
You must keep records for 5 years after the relevant transaction. Records should include:
- Receipts of purchase
- Exchange records
- Wallet addresses
- Transaction IDs
- Broker statements
Summary Table
| Scenario | Tax Treatment |
|---|---|
| Buy BTC, sell after 2 years ($5,000 gain) | Taxable, 50% CGT discount applies |
| Trade ETH for SOL (held 6 months) | Taxable, no discount |
| Stake ADA, receive $1,000 in rewards | Taxable as income |
| Buy coffee with BTC (under $10,000) | Exempt (personal use) |
| Receive airdrop, hold | Not taxable until sold |
Bottom Line
Australia’s crypto tax rules are clear but strict. The 50% CGT discount for holdings over 12 months is valuable — plan your sales around it. Use crypto tax software to calculate gains and losses. And remember: the ATO’s data matching means you should report everything, even small trades.
