How to Tax Crypto Australia: ATO Rules and CGT Steps
One swap from Ethereum to Solana can create a tax bill even though you never touched a dollar. Crypto-to-crypto trading is still a taxable event. This guide covers what is taxable, how to calculate it, and what to put on your return.
How the ATO Sees Crypto
Cryptocurrency is generally treated as a CGT asset rather than money or foreign currency. It is a CGT asset, much like shares or property. Your tax treatment depends on why you hold it.
| Item | ATO treatment |
|---|---|
| Asset class | CGT asset (property) |
| Who pays | Australian tax residents on worldwide crypto, including foreign exchanges |
| Financial year | 1 July to 30 June |
| Self-lodged return deadline | — |
| Capital gains discount | — |
| Capital losses | — |
| Record retention | Five years |
| Trader or business | May be ordinary income or trading stock instead of CGT |
For context, as of November 7, 2026, Bitcoin is at $75,852 and Ethereum at $2,239 (USD). Your tax calculation must convert every transaction into AUD at the time it occurs, not use USD figures.
7 Crypto Events That Trigger Tax in Australia
- Selling crypto for AUD. The gain or loss is the AUD proceeds minus your cost base.
- Swapping one crypto for another. Trading ETH ($2,239) for SOL ($90.14) disposes of the ETH. The capital proceeds are the AUD market value of the SOL received.
- Spending crypto on goods or services. Paying for a laptop with BTC is a disposal at the AUD value of the item or the crypto at that time.
- Gifting or donating crypto. A gift is a disposal at market value, with some exceptions for deductible gift recipients.
- Converting to a stablecoin. Moving BTC into USDT or USDC is a disposal of the BTC, even if you never leave the exchange.
- Receiving income in crypto. Salary, staking rewards, mining rewards and airdrops can be ordinary income at their AUD value when received.
- Losing access or having crypto stolen. This may produce a capital loss, but only with evidence such as wallet records and proof you held the private keys.
What Is Not Taxable
- Buying crypto with AUD and holding it. No tax until you dispose of it.
- Transferring between your own wallets. Moving coins from an exchange to your hardware wallet is not a CGT event. Keep records proving both wallets are yours.
- Personal use asset exemption. Crypto acquired and used mainly to buy items for personal use may be exempt in some cases, but Crypto held as an investment does not qualify.
- Capital losses. They are not taxed, but they cannot reduce salary or other income.
How to Calculate Your Capital Gain
The formula is: capital proceeds minus cost base = capital gain or loss. The cost base includes the AUD purchase price plus transaction costs such as exchange fees and brokerage.
Hypothetical worked example
These numbers are illustrative only. You buy ETH for A$4,000 including fees and sell it for A$7,000.
| Scenario | Gain | Taxable portion |
|---|---|---|
| Held 8 months | A$3,000 | A$3,000 (no discount) |
| Held 14 months | A$3,000 | A$1,500 (50% discount) |
The taxable portion is added to your other income and taxed at your marginal rate. Check the current brackets on the ATO website before you lodge.
Netting gains and losses
- Subtract current-year capital losses from current-year capital gains.
- Subtract any carried-forward losses from earlier years.
- Apply any CGT discount to what remains, if the assets qualify.
Capital losses are applied before the discount. That order matters, so keep it in mind when you use software.
Choosing a cost-base method
If you hold several parcels of the same coin bought at different prices, you must work out which parcel you sold. Specific identification may be possible when you keep records that show which units were sold. If you cannot identify them, the usual fallback is first in, first out (FIFO). Pick one method and apply it consistently.
Crypto Income: Staking, Mining and Airdrops
Some activity creates ordinary income, not a capital gain. You declare the AUD market value at the moment you receive the asset.
| Activity | Typical treatment |
|---|---|
| Staking rewards | Ordinary income when received |
| Mining as a hobby | Generally income when received; business miners deduct related costs |
| Airdrops | Ordinary income when received, depending on circumstances |
| Crypto salary | Ordinary income at AUD value received |
| Later sale of rewarded coins | CGT event; cost base is the AUD value declared as income |
This creates two tax events for one coin: income on receipt and CGT on sale. If you declared the reward at A$100 and later sold at A$150, your capital gain is A$50, not A$150.
DeFi activities such as liquidity pools, wrapped tokens and lending have more complex outcomes. The treatment depends on the structure. Use a registered tax agent for these.
Step-by-Step: Reporting Crypto on Your Return
- Export all transaction history. Pull CSV files from every exchange, wallet and DeFi protocol you used between 1 July and 30 June.
- Convert to AUD. Use a consistent source for AUD rates and record the rate for each transaction.
- Separate income from disposals. Tag staking, mining and airdrops as income. Tag sales, swaps and spending as CGT events.
- Calculate gains and losses per disposal. Apply your chosen cost-base method.
- Apply losses, then the discount. Net current and carried-forward losses first.
- Complete the return. Answer the crypto and capital gains questions and enter the net capital gain. Add crypto income under the relevant income item.
- Keep your records. Store exports, wallet addresses, dates, AUD values and the method used.
If you use a tax agent, confirm your lodgement date with your agent.
Expert Notes: Common Errors and Fixes
Most reporting problems come from incomplete data, not from the tax rules themselves. These are the errors that cause trouble:
- Missing cost base after a wallet transfer. Exchange CSVs show a withdrawal but not what you paid. Fix: match the transfer to the original purchase so the cost base follows the coins.
- Treating transfers as sales. Tools sometimes read a transfer between your own wallets as a disposal, which inflates gains. Fix: label both wallets as yours.
- Using USD figures. Gains must be reported in AUD. Fix: apply an AUD rate to each transaction.
- Forgetting exchanges you closed. Fix: request historical exports before an account disappears.
- Claiming the 12-month discount on short holds. Count from the acquisition date to the disposal date. Fix: check each parcel, not just the coin.
- Treating a trading business as a hobby. Frequent, organised, profit-driven trading may be a business. Fix: get advice before you assume the CGT discount applies.
As a trade-off, specific identification can lower your tax by letting you sell high-cost parcels first, but it demands detailed records. FIFO is easier to defend but often produces larger gains in a rising market. Crypto tax software can automate the work, but you remain responsible for the numbers, so review every flagged transaction.

FAQ
What is crypto tax in Australia?
It is the tax on gains and income from crypto. The ATO treats crypto as a CGT asset, so disposals trigger capital gains tax, and rewards such as staking can count as ordinary income.
How to tax crypto Australia if I only swapped coins?
Treat each swap as a sale of the coin you gave up. Find its AUD market value at the time, subtract your cost base, and report the gain or loss. No AUD needs to reach your bank account.
Is it safe to skip reporting small crypto trades?
No. All disposals count regardless of size. Underreporting can lead to penalties. Report every disposal, including small ones.
Why do I pay less tax if I hold for 12 months?
A CGT discount may apply to assets held for at least 12 months, depending on who holds them.
Do I pay tax on crypto I bought and still hold?
No. Buying and holding does not trigger tax. Tax arises when you sell, swap, spend or gift it, or when you receive crypto as income.
Can crypto losses reduce my salary tax?
No. Capital losses only offset capital gains. Unused losses can be carried forward to future years, provided you keep records.
