Crypto Tax in Australia 2025-26: How the ATO Taxes Cryptocurrency

Real talk — The ATO treats cryptocurrency as property, not as currency or money. This means that every time you dispose of crypto — whether by selling it for Australian dollars, trading it for another cryptocurrency, spending it to buy goods or services, gifting it, or converting it to a stablecoin — a capital gains tax (CGT) event occurs.

You must calculate the capital gain or loss on each transaction by comparing the cost base (what you paid, including transaction fees) to the sale proceeds or market value at the time of disposal. The ATO has access to data from Australian crypto exchanges under a data-matching program and has publicly stated that cryptocurrency is a priority compliance area. They have sent warning letters to hundreds of thousands of Australian crypto holders reminding them of their tax obligations.

Failing to report crypto disposals can result in penalties and interest charges.

When you sell or trade crypto at a profit, the capital gain is added to your taxable income and taxed at your marginal rate. If you held the crypto for at least 12 months, you qualify for the 50% CGT discount, meaning only half the gain is taxable.

For example, if you bought Bitcoin for $20,000 and sold it 18 months later for $35,000, the capital gain is $15,000, and after the 50% discount, $7,500 is added to your taxable income. At a 37% marginal rate, the tax would be $2,775. If you held it for less than 12 months, the full $15,000 would be taxable, resulting in $5,550 tax.

One thing people miss: Capital losses on crypto can be offset against other capital gains (including property and shares) but can't be deducted from ordinary income. Unused capital losses carry forward to future years. This makes the 12-month holding period a significant tax planning consideration for crypto investors. Pretty straightforward once you know.

Every crypto-to-crypto trade is a CGT event, even if you never convert back to Australian dollars. Swapping Bitcoin for Ethereum, trading tokens on a decentralised exchange, providing liquidity to a DeFi pool, and wrapping tokens are all taxable events.

This can create a significant compliance burden for active traders who may have hundreds or thousands of transactions per year. DeFi activities add further complexity: providing liquidity to a pool triggers a disposal of the deposited tokens, earning yield generates income, and removing liquidity triggers another CGT event. Lending platforms, staking protocols, and yield farming all have tax implications.

The ATO has released limited specific guidance on DeFi, which means taxpayers need to apply general CGT principles to these complex transactions. Using dedicated crypto tax software that can connect to exchanges and wallets is strongly recommended.

Crypto received through mining is treated differently depending on whether you're mining as a hobby or a business. For hobby miners, the crypto received is not taxed at the time of receipt, but you pay CGT when you later sell or trade it (with a cost base of zero or the market value at receipt, depending on interpretation).

Heads up — For business miners, the crypto is assessable as ordinary income at the market value on the date received. Staking rewards are generally treated as ordinary income at the time they're received, valued at the fair market value on that date. When you later sell staked tokens, you pay CGT on any gain above the cost base (which is the value at which they were included in your income).

Airdrops of new tokens are treated as ordinary income if you've done something to earn them, or may have a zero cost base if received unexpectedly. In all cases, detailed records of the date, quantity, and market value at receipt are essential.

The ATO provides a limited personal use exemption for crypto used to buy goods or services for personal consumption, but only if the crypto was acquired for less than $10,000 and used within a short time. This exemption is narrow and doesn't apply to crypto held as an investment, even if you eventually use it to buy something.

If you bought Bitcoin three years ago and use it to buy a coffee today, the personal use exemption doesn't apply — it's a CGT event. NFTs (non-fungible tokens) are also subject to CGT as digital assets. Buying an NFT with crypto triggers a CGT event on the crypto disposal, and selling an NFT later triggers a CGT event on the NFT itself.

Artists who create and sell NFTs may be taxed on the proceeds as ordinary business income rather than capital gains. The NFT space remains a grey area in Australian tax law, and professional advice is recommended for significant transactions.

This bit matters. The ATO requires you to keep records of every crypto transaction for at least five years. Records must include the date of each transaction, the quantity and type of crypto involved, the value in Australian dollars at the time of the transaction, what the transaction was for (buy, sale, trade, gift, etc.), the other party's wallet address (if applicable), exchange records, and agent or accountant costs.

Given the volume of transactions many crypto users generate, manual record-keeping is impractical. Crypto tax software like Koinly, CryptoTaxCalculator, or Syla connect to your exchange accounts and wallets, automatically categorise transactions, calculate capital gains and losses, and generate ATO-compliant tax reports. These tools typically cost $50 to $200 per year depending on the number of transactions.

Given the ATO's focus on crypto compliance and the complexity of the calculations, investing in proper record-keeping tools is essential.
