1. Legal Basis: Why Crypto Is Not Foreign Currency
The Australian Taxation Office (ATO) has consistently held that cryptocurrencies such as Bitcoin, Ethereum, and other digital assets are not foreign currency for Australian tax purposes. Instead, they are treated as property—and therefore as CGT assets under the Income Tax Assessment Act 1997 (ITAA 1997)[reference:0][reference:1].
This position is formally set out in ATO Taxation Determination TD 2014/25 (as amended by TD 2014/25A1), which states that Bitcoin is not a 'foreign currency' for the purposes of Division 775 of the ITAA 1997[reference:2]. The Treasury Laws Amendment (2022 Measures No. 4) Act 2023 further amended the definition of 'foreign currency' to exclude digital currency (including Bitcoin), with effect for income years starting from 1 July 2021[reference:3][reference:4].
2. Crypto as a CGT Asset
Under Australian tax law, a CGT asset is any form of property, including shares, real estate, and—crucially—crypto assets[reference:5]. The ATO explicitly lists crypto assets among assets subject to CGT[reference:6]. This means that when you dispose of a crypto asset, you may make a capital gain or capital loss[reference:7].
The most common use of crypto is as an investment, in which case the crypto asset is a CGT asset[reference:8]. If you acquire a crypto asset as an investment, transactions such as disposal, exchange, or swap are CGT events[reference:9].
✅ CGT applies when you:
- Sell crypto for Australian dollars (AUD)
- Swap one crypto asset for another
- Use crypto to buy goods or services
- Gift crypto to another person
- Convert crypto to foreign currency
❌ CGT does not apply when you:
- Simply hold crypto (no disposal)
- Transfer crypto between your own wallets
- Acquire crypto and never dispose of it
Note: Staking rewards and airdrops may be ordinary income, not CGT—see ATO guidance.
3. Taxable Events That Trigger CGT
A CGT event occurs when you dispose of a crypto asset[reference:10]. The ATO defines a disposal as occurring when you do any of the following[reference:11]:
- Sell a crypto asset
- Gift a crypto asset
- Trade, exchange, or swap a crypto asset for another crypto asset
- Convert a crypto asset to Australian or foreign currency (fiat currency)
- Buy goods or services with a crypto asset
Each of these events requires you to calculate whether you made a capital gain or loss[reference:12]. The timing of the CGT event is generally the date of the transaction[reference:13].
| Transaction Type | CGT Event? | Valuation Required |
|---|---|---|
| Sell crypto for AUD | ✅ Yes | AUD value at time of sale |
| Swap crypto for another crypto | ✅ Yes | AUD value of each asset at time of swap |
| Use crypto to buy goods/services | ✅ Yes | AUD value of crypto at time of purchase |
| Gift crypto | ✅ Yes | Market value in AUD at time of gifting |
| Transfer between own wallets | ❌ No | Not applicable (no disposal) |
| Hold crypto (no disposal) | ❌ No | Not applicable |
4. Recordkeeping Essentials
The ATO requires you to keep records of each of your crypto assets and every transaction to work out if you have made a capital gain or loss[reference:16]. Good records are essential for meeting your tax obligations[reference:17].
What to Record
- Receipts when you buy, transfer, or dispose of crypto assets[reference:18]
- Date of each transaction[reference:19]
- Purpose of the transaction and the other party (or crypto address)[reference:20]
- Exchange records and wallet details[reference:21]
- Value in Australian dollars at the time of each transaction[reference:22]
- Agent, accountant, and legal costs[reference:23]
- Digital wallet records and keys[reference:24]
- Software costs related to managing your tax affairs[reference:25]
How Long to Keep Records
You must keep records for 5 years from the later of:
- When you prepare or obtain the records
- When transactions or acts are complete
- The year that the CGT event happens[reference:26]
📋 Recordkeeping Checklist
- Export your transaction history regularly—at least every 3 months[reference:27]
- Export complete history before closing any exchange account[reference:28]
- Use a reputable Australian crypto tax calculator to sync exchange and wallet accounts[reference:29]
- If records are lost, use a blockchain explorer or contact exchange customer service[reference:30]
- Keep records in English (or translatable to English)[reference:31]
- Records may be electronic or paper[reference:32]
5. Reporting Basics
You must report capital gains and losses from crypto transactions in your tax return for the income year in which the CGT event occurred[reference:33]. If you are lodging online with myTax, follow the instructions for Capital gains or losses[reference:34].
The ATO operates a crypto asset data-matching program that acquires account identification and transaction data from designated service providers[reference:35]. This data is matched to ATO systems to identify taxpayers who have failed to report crypto disposals[reference:36].
Calculating your CGT: Your net capital gain for the year is:
- Total capital gains
- Less any capital losses
- Less any CGT discount entitlement[reference:37]
If you hold a crypto asset for at least 12 months before disposing of it, you may be entitled to the 50% CGT discount (for individuals)[reference:38]. However, note that proposed changes in the 2026 Federal Budget would affect how capital gains are taxed from 1 July 2027[reference:39]. Always verify current rules with the ATO or a registered tax professional.
6. Personal Use Asset Exemption
There is a limited exemption from CGT for crypto assets that qualify as personal use assets. A crypto asset is a personal use asset if you keep or use it mainly for personal use or consumption—for example, to buy items for personal use[reference:40].
A capital gain on the disposal of a crypto asset is exempt from CGT if[reference:41]:
- It is a personal use asset, and
- You acquired it for less than $10,000
Capital losses on personal use assets are disregarded—you cannot use them to offset other capital gains[reference:42].
7. Common Mistakes
- ❌ Treating crypto as foreign currency: Many taxpayers mistakenly apply foreign currency rules to crypto. The ATO is clear: crypto is not foreign currency for CGT purposes[reference:46].
- ❌ Failing to record every transaction: Even small trades, swaps, and purchases count. The ATO's data-matching program can detect unreported transactions[reference:47].
- ❌ Assuming the personal use exemption applies to investments: If you hold crypto mainly as an investment, the personal use exemption does not apply—even if you occasionally use it to buy something[reference:48].
- ❌ Not keeping records for 5 years: The ATO requires records to be kept for 5 years from the date of the CGT event or when you prepare the records[reference:49].
- ❌ Forgetting to convert to AUD: All values must be in Australian dollars at the time of each transaction[reference:50].
- ❌ Ignoring staking and airdrop income: Rewards from staking or airdrops may be ordinary income (not CGT) and must be declared separately[reference:51].
8. Practical Example
📘 Scenario: Elena's Crypto Investment
Elena buys 1 Bitcoin (BTC) for AUD 30,000 on 1 August 2025. She holds it as an investment. On 15 October 2026, she sells the BTC for AUD 55,000.
What happens for tax purposes?
- Elena has made a capital gain of AUD 25,000 (proceeds of AUD 55,000 minus cost base of AUD 30,000).
- Because she held the asset for more than 12 months (from August 2025 to October 2026), she may be entitled to the 50% CGT discount (subject to current rules).
- If the discount applies, her taxable capital gain would be AUD 12,500.
- She must report this gain in her tax return for the 2026–27 income year.
- She must keep records of the purchase, sale, and all supporting documentation for at least 5 years.
Note: This example is illustrative only. Tax outcomes depend on individual circumstances. Always verify current CGT discount rules, as legislative changes may apply from 1 July 2027[reference:52].
9. Risk Warning
⚠️ Regulatory and Compliance Risks
- Data-matching enforcement: The ATO actively matches transaction data from crypto exchanges with tax returns[reference:53]. Failure to report crypto disposals can result in penalties and interest.
- Legislative uncertainty: Tax rules for crypto assets are evolving. Proposed changes—such as the removal of the 50% CGT discount from 1 July 2027—may affect future tax outcomes[reference:54].
- International reporting: Australia is implementing the OECD Crypto-Asset Reporting Framework (CARF), which will enable automatic exchange of crypto transaction data with other jurisdictions[reference:55].
- Exchange stability: Crypto exchanges can close or become inaccessible[reference:56]. Regularly export your transaction history to avoid losing records.
- Valuation complexity: Crypto markets are volatile. Accurate valuation in AUD at the time of each transaction is essential—and can be challenging without proper records.

10. Frequently Asked Questions
Why doesn't the ATO treat cryptocurrency as foreign currency?
The ATO's position, confirmed in Taxation Determination TD 2014/25, is that Bitcoin and other cryptocurrencies are not legally recognised as a unit of account or form of payment by any sovereign country. Therefore, they do not qualify as 'foreign currency' under Division 775 of the ITAA 1997[reference:57][reference:58]. Legislative amendments from 2021 explicitly exclude digital currency from the definition of foreign currency[reference:59].
Do I pay CGT on every crypto transaction?
Not every transaction triggers CGT. You only have a CGT event when you dispose of a crypto asset—for example, by selling, swapping, gifting, or using it to buy goods or services[reference:60]. Simply holding crypto or transferring it between your own wallets does not trigger CGT.
What is the CGT discount and how does it apply to crypto?
If you are an individual and you hold a crypto asset for at least 12 months before disposing of it, you may be entitled to a 50% CGT discount on the capital gain[reference:61]. However, proposed changes from 1 July 2027 may remove this discount[reference:62]. Always verify the current rules.
How do I value my crypto in Australian dollars for tax purposes?
You must convert the value of your crypto assets to Australian dollars at the time of each transaction[reference:63]. From 1 January 2020, the ATO uses exchange rates from the Reserve Bank of Australia[reference:64]. For currencies not listed, you may use any reasonable externally sourced exchange rate[reference:65].
What records do I need to keep for crypto tax?
You must keep records of every transaction, including receipts, dates, transaction purposes, exchange records, AUD values at the time of each transaction, wallet records, and any associated costs[reference:66]. Records must be kept for 5 years[reference:67].
Does the personal use asset exemption apply to my crypto?
Only if you keep or use the crypto mainly for personal use or consumption, and you acquired it for less than $10,000[reference:68]. If you hold crypto as an investment, the exemption does not apply[reference:69]. The determination is made at the time of disposal[reference:70].
What happens if I don't report my crypto transactions?
The ATO operates a data-matching program that acquires transaction data from crypto exchanges[reference:71]. If you fail to report disposals, you may face penalties, interest charges, and potential audit. It is important to report all taxable transactions accurately.
Are staking rewards and airdrops taxed as CGT or income?
Rewards from staking and airdrops are generally treated as ordinary income at the time you receive them, not as CGT[reference:72]. The cost base of the asset may be adjusted accordingly. You should declare these as income in your tax return.
