Crypto Tax Australia 2026: ATO Rules for Bitcoin, Ethereum & NFTs

15 March 2026|6 min read

How the ATO taxes cryptocurrency in 2026. Understand CGT on Bitcoin and Ethereum, disposal events, the 50% discount, DeFi and staking income, and the ATO's exchange data-matching program.

Crypto is a CGT asset: the basic rule

The ATO treats cryptocurrency as property, not as currency. This means every cryptocurrency — Bitcoin, Ethereum, stablecoins, meme coins, governance tokens, and NFTs — is a capital gains tax (CGT) asset. When you dispose of a crypto asset, you must calculate whether you made a capital gain or loss and report it on your tax return. The cost base of your crypto includes the purchase price in AUD at the time of acquisition plus any exchange fees and transaction costs (gas fees for Ethereum transactions, for example). If you received crypto for free — through an airdrop, fork, or reward — the cost base is the market value at the time you received it, and you may also have ordinary income to declare at the time of receipt. There is one narrow exception: if you acquired crypto purely for personal use (such as buying a small amount of Bitcoin solely to purchase goods online) and the cost was under $10,000, it may qualify as a personal use asset and be exempt from CGT. However, the ATO applies this exception very narrowly — if you held the crypto for any period as an investment or if the total cost exceeds $10,000, the personal use exemption does not apply.

Disposal events: sell, trade, spend, and gift

A CGT event occurs whenever you dispose of cryptocurrency. The ATO defines disposal broadly to include selling crypto for Australian dollars or any fiat currency, trading one cryptocurrency for another (swapping BTC for ETH is a disposal of BTC and an acquisition of ETH), using crypto to purchase goods or services (buying a coffee with Bitcoin triggers CGT on the Bitcoin disposed of), gifting crypto to another person (the market value at the time of the gift is the capital proceeds), converting crypto to a stablecoin (this is a crypto-to-crypto trade), and transferring crypto to a DeFi protocol in exchange for tokens. Each disposal requires a separate CGT calculation. If you bought 1 BTC at $40,000 and later traded it for Ethereum when 1 BTC was worth $65,000, you have a $25,000 capital gain on the Bitcoin disposal, and your cost base for the acquired Ethereum is $65,000. Simply transferring crypto between your own wallets (without changing ownership or receiving different tokens) is not a CGT event. Moving Bitcoin from Coinbase to a hardware wallet, for example, does not trigger any tax obligation.

The 50% CGT discount: hold for 12 months

If you hold a cryptocurrency asset for at least 12 months before disposing of it, you are entitled to the 50% CGT discount — meaning only half of the capital gain is added to your taxable income. This discount can dramatically reduce your tax bill. For example, if you bought Ethereum for $10,000 and sold it 14 months later for $25,000, your capital gain is $15,000. With the 50% discount, only $7,500 is taxable. At a 30% marginal rate (plus 2% Medicare levy), you would pay $2,400 instead of $4,800. The 12-month holding period is calculated from the acquisition date to the disposal date. If you acquired crypto through multiple purchases at different times, each parcel has its own acquisition date. When you sell part of your holdings, you must identify which specific parcel you are disposing of — the ATO accepts FIFO (first in, first out) or specific identification methods. Choosing the right method can make a meaningful difference. If your earliest parcel was purchased more than 12 months ago and has a lower cost base, FIFO gives you the 50% discount. If a more recent parcel has a higher cost base (and thus a smaller gain), specific identification might produce a better outcome.

DeFi, staking, and yield income

Decentralised finance (DeFi) activities create tax obligations that many crypto users overlook. Staking rewards — whether from proof-of-stake networks, liquidity pools, or yield farming — are generally treated as ordinary income at the market value when you receive them. This means staking rewards are taxed at your marginal tax rate in the year received, not as capital gains. The cost base for these tokens is the market value at the time of receipt, and if you later sell or trade them, any increase in value is a separate capital gain. Providing liquidity to a DeFi protocol typically involves exchanging your tokens for liquidity pool (LP) tokens — this is a disposal of the original tokens and triggers CGT. When you withdraw liquidity, you dispose of the LP tokens and reacquire the underlying assets, potentially triggering another CGT event. Lending crypto and earning interest creates ordinary income at the time the interest is received. Governance token rewards from protocol participation are similarly ordinary income. The ATO has not issued comprehensive guidance on every DeFi scenario, but the general principles of CGT and ordinary income apply. Keep detailed records of every DeFi interaction including transaction hashes, dates, token amounts, and market values.

Record keeping for crypto

The ATO requires you to keep records of every crypto transaction for at least five years. Required records include the date of each transaction, the type of transaction (buy, sell, trade, transfer, stake, earn), the amount of crypto and its value in AUD at the time, exchange or platform used, transaction fees and gas fees, wallet addresses involved, and the purpose of the transaction (investment, personal use, business). With hundreds or thousands of transactions across multiple exchanges and wallets, manual record keeping is practically impossible for active traders. Crypto tax software — such as Koinly, CryptoTaxCalculator (an Australian company), or Syla — can import transaction histories from exchanges and blockchains, match buy and sell pairs, calculate capital gains and losses, and generate ATO-ready tax reports. Most of these services cost between $49 and $199 per year depending on transaction volume. Start tracking from your very first crypto purchase. If you have historical transactions without records, most exchanges allow you to download full transaction histories going back years, and blockchain explorers can verify on-chain transactions.

ATO data matching: exchanges report to the ATO

The ATO operates a cryptocurrency data-matching program that collects transaction data from Australian crypto exchanges. Exchanges including CoinSpot, Swyftx, Independent Reserve, BTC Markets, Coinbase, and others are required to report customer identity and transaction details to the ATO. The program covers approximately 1.2 million Australians who have bought or sold crypto. The ATO uses this data to identify taxpayers who have disposed of crypto but did not report capital gains, taxpayers who received crypto income (staking, interest) but did not declare it, and discrepancies between reported figures and exchange data. The ATO has stated that crypto is a priority area for compliance activity and has sent warning letters to hundreds of thousands of taxpayers. Penalties for not declaring crypto gains range from 25% of the tax shortfall (for failing to take reasonable care) to 75% (for intentional disregard). The ATO can also apply interest on the unpaid tax. International exchanges are harder for the ATO to access directly, but the Common Reporting Standard (CRS) and bilateral tax treaties are expanding international data sharing.
