Crypto Tax Australia 2026-27: How Bitcoin, ETH and DeFi Are Taxed

The ATO's crypto data-matching program captured records for an estimated 1.2 million Australians in 2025-26. It collects transaction data directly from Australian exchanges — Coinbase, CoinSpot, Swyftx, Independent Reserve — and cross-references it with lodged tax returns. If you bought, sold or swapped crypto in 2025-26 and haven't declared it, the ATO likely already knows.

Crypto tax in Australia is not as complicated as the industry makes it sound, but there are genuinely confusing rules around DeFi, staking and swaps that most people get wrong. This guide covers the complete ATO position on every crypto activity, with worked dollar examples for the scenarios that actually matter.

How the ATO classifies crypto

The ATO does not treat cryptocurrency as money or foreign currency. It treats it as property — specifically as a CGT asset, the same legal category as shares, investment property, and collectibles.

This classification has one major practical consequence: every time you dispose of crypto, you trigger a capital gains tax (CGT) event. The profit (or loss) is calculated as the difference between what you received for it and your cost base (what you paid, including transaction fees to acquire it).

For the 2025-26 income year, two taxes can apply to your crypto activity:

Capital Gains Tax — when you dispose of crypto held as an investment
Income Tax — when you receive crypto as payment for work, staking rewards, or airdrops

CGT events: what does and doesn't trigger tax

The most important thing most Australians get wrong is thinking that only selling crypto for Australian dollars triggers tax. It doesn't work that way.

These are all disposal events that trigger CGT:

Action	CGT event?	Why
Sell crypto for AUD	✅ Yes	Direct disposal
Swap BTC for ETH	✅ Yes	Disposal of BTC, acquisition of ETH
Spend crypto on goods or services	✅ Yes	Disposal at market value on the day
Gift crypto to another person	✅ Yes	Disposal at market value on the day
Trade crypto on a DEX	✅ Yes	Disposal of one asset, acquisition of another
Wrap tokens (e.g. ETH → WETH)	✅ Yes	ATO treats wrapping as a disposal
Add crypto to a liquidity pool	✅ Yes	Disposal of crypto in exchange for LP tokens
Remove from a liquidity pool	✅ Yes	Disposal of LP tokens, re-acquisition of crypto
Transfer between your own wallets	❌ No	Same owner, no disposal
Buy crypto with AUD	❌ No	Acquisition only, no disposal
Hold crypto	❌ No	No disposal

The crypto-to-crypto rule trips up the most people. Swapping Bitcoin for Ethereum is not a tax-free exchange — it is a disposal of Bitcoin (triggering CGT on any gain since you bought it) and an acquisition of Ethereum (with a new cost base at today's price). Many holders have a tax liability from swaps they performed years ago without realising.

How to calculate your crypto capital gain

Step 1: Establish your cost base Your cost base is what you paid for the crypto, plus any transaction fees (exchange fees, gas fees) to acquire it. For crypto bought in multiple parcels at different times, you need to track each parcel separately.

Step 2: Calculate the proceeds The proceeds are the AUD value at the time of disposal — the selling price if you sold for AUD, or the market value of what you received if you swapped or spent it.

Step 3: Calculate the gross gain Gain = Proceeds − Cost base

Step 4: Apply the 12-month discount (if eligible) If you held the asset for more than 12 months before disposal, you can reduce the taxable gain by 50%.

Step 5: Add to your other income and pay tax at your marginal rate The taxable capital gain is added to your assessable income and taxed at your marginal rate.

Worked example — Bitcoin sale:

Sarah bought 0.5 BTC in January 2024 for $30,000 (including exchange fees). She sold it in March 2026 for $72,000. She held for more than 12 months, so the 50% discount applies.

Proceeds: $72,000
Cost base: $30,000
Gross gain: $42,000
Less 50% CGT discount: $21,000
Taxable gain: $21,000
Sarah earns $90,000 from her job. Her marginal rate is 32.5%.
CGT payable: $21,000 × 32.5% = $6,825

Worked example — Crypto-to-crypto swap:

Tom bought 1 ETH for $4,000 in June 2023. In August 2024 (14 months later) he swapped it for $8,000 worth of SOL. This is a disposal of ETH.

Proceeds: $8,000 (market value of ETH at swap)
Cost base: $4,000
Gross gain: $4,000
50% discount applies (held 14 months): taxable gain = $2,000
Tom is on $80,000 income, marginal rate 32.5%
CGT payable: $2,000 × 32.5% = $650

Tom now holds SOL with a cost base of $8,000 — the market value on the day of the swap.

Identifying which parcel you're selling: When you have multiple purchases of the same crypto at different prices and different dates, the cost base method you use affects your tax. The ATO allows:

First In First Out (FIFO): The first crypto you bought is treated as the first you sold
Last In First Out (LIFO): The most recent purchase is treated as the first sold
Specific identification: You nominate exactly which parcel you're disposing of

You must choose a method and apply it consistently. FIFO is the most commonly used and is accepted by all major crypto tax software tools.

The 12-month CGT discount — current rules and what changes in 2027

Under current rules, holding a crypto asset for more than 12 months before disposal reduces your taxable gain by 50%. This is one of the most significant tax concessions available to Australian crypto investors.

From 1 July 2027, this changes. The 50% CGT discount will be replaced by a CPI indexation method for most investors, with a 30% minimum tax applying as a floor. The implications for crypto:

Scenario	Current rule	From July 2027
Hold BTC 15 months, sell	50% of gain taxable	Indexed gain taxable, minimum 30% tax
Crypto bought before July 2027, sold after	Old 50% discount for pre-2027 gain portion	Split using time apportionment
Lower income earner (16% or 30% bracket)	Pays 8–15% effective CGT	Will pay minimum 30% on gains (new floor)

The key impact on lower-income crypto investors: Under current rules, someone on a $45,000 salary with a $20,000 gain held 12+ months pays an effective CGT rate of about 8% (50% discount + 16% marginal rate). From July 2027, the 30% minimum tax means they'd pay at least 30% on the indexed gain. This is a significant increase for holders in lower brackets.

What to consider now: Crypto held since before 2025 and sold before 1 July 2027 will use the current 50% discount entirely. For long-term holders with large unrealised gains, the sell-before-2027 question is worth modelling. See our full guide to whether selling before July 2027 makes sense.

Staking, airdrops and yield farming — income tax, not CGT

This is where most crypto guides mislead people. Staking rewards and most airdrops are not CGT events — they are ordinary income, assessed in the year you receive them.

Staking rewards: When you receive tokens from staking, the ATO requires you to include the market value of those tokens on the day you receive them as assessable income in your tax return, under "other income."

You then have a cost base for those tokens equal to the amount you declared as income. When you eventually sell them, any additional gain (or loss) is a capital gain from that new cost base.

Example: In March 2026, Priya receives 50 SOL in staking rewards. On that day, SOL is trading at $180. She must declare $9,000 as income in her 2025-26 tax return. Her cost base for those 50 SOL is $9,000. If she sells in 2027 for $11,000, she has a $2,000 capital gain (with a 12-month discount if she held long enough).

Airdrops: The ATO's position on airdrops is nuanced:

If you receive an airdrop because you hold an existing token (a "qualifying" airdrop from a protocol you already use), the ATO may treat it as income at market value on receipt.
If you receive tokens from a completely new protocol with no connection to your existing holdings, the ATO may accept a nil cost base with all proceeds on eventual sale being a capital gain.
In practice, most airdrop recipients treat the value at receipt as income. Use the ATO's guidance and get advice if the amount is significant.

Yield farming: Rewards from providing liquidity or yield farming are generally treated as income when received. The ATO's position is that where crypto is received in exchange for a service (including providing liquidity), the market value at receipt is assessable income.

DeFi — the specific rules you need to know

Decentralised finance has created a category of crypto activity the ATO has been progressively clarifying. Here is the current position:

Wrapping and unwrapping tokens (e.g., ETH → WETH, BTC → WBTC): The ATO confirmed that wrapping a token is a CGT disposal of the original token and acquisition of the wrapped token. If you wrapped ETH held for 18 months, you have disposed of it — the 12-month discount would apply, but you also have a gain or loss to calculate at the time of wrapping.

Liquidity pools: Adding crypto to a liquidity pool (e.g., on Uniswap or Curve) is treated as a disposal of the crypto assets you add, in exchange for liquidity pool (LP) tokens. When you remove liquidity, the LP tokens are disposed of and you reacquire the underlying assets.

Each of these is a CGT event. The impermanent loss you may experience is a factual loss — it affects your cost base calculations but doesn't create an automatic deduction outside of the usual capital loss rules.

Borrowing against crypto (e.g., via Aave or Compound): The ATO's position is that using crypto as collateral for a loan does not trigger a CGT event — the crypto has not been disposed of. However, if the loan is liquidated (your collateral is forcibly sold), that liquidation is a disposal and triggers CGT.

NFT tax rules

The ATO treats NFTs using the same framework as other crypto assets. The tax outcome depends on what you're doing:

NFT activity	Tax treatment
Buy an NFT and sell it later at a profit	CGT — same rules as any crypto asset
Sell an NFT held 12+ months	50% CGT discount applies (current rules)
Create and sell NFTs as a business	Ordinary income (not CGT) — business income rules apply
Receive an NFT as payment for services	Income at market value on receipt
Gift an NFT	Disposal at market value — CGT applies
An NFT becomes worthless	Capital loss — can offset against capital gains

The "creator vs investor" distinction matters most. Someone who regularly creates and sells NFT art is running a business — the proceeds are income, not capital gains, and the 50% CGT discount does not apply.

The personal use exemption — why it almost never applies

The ATO allows a personal use asset exemption for crypto that you buy and quickly use to acquire goods or services for personal consumption. The key conditions:

The crypto must be acquired and used specifically and mainly for personal purchases (not held as an investment)
It must be used within a short period — the ATO doesn't define this precisely, but days to weeks is the implied intent
The acquisition cost must be less than $10,000 (gains on personal use assets costing more than $10,000 are still taxable)

In practice, this exemption is narrow. If you bought Bitcoin, held it for any meaningful period, and its value appreciated before you spent it, the ATO will almost certainly view it as an investment asset — not a personal use asset. The exemption was designed for someone who buys a small amount of crypto specifically to use on a purchase immediately, not someone who has an investment portfolio and occasionally spends some.

Do not rely on this exemption unless the facts genuinely match: small amount, used quickly, personal purpose from the outset.

Record keeping — what you need for every transaction

The ATO requires records to be kept for five years from the date you lodge your return. For every crypto transaction you must be able to document:

The date of the transaction
The amount of crypto involved
The value in AUD at the time (exchange rate or market price)
What the transaction was for (purchase, sale, swap, staking reward, etc.)
The exchange or wallet address involved
Transaction fees (these form part of your cost base)

The AUD valuation problem: When you swap crypto-to-crypto at 11pm using a DEX, there's no automatic AUD receipt. You need to know the AUD price of both assets at that exact time. Major exchanges publish historical price data; dedicated crypto tax software typically handles this automatically.

Practical solution for 2025-26: Australian crypto tax software platforms (such as Koinly, CoinTracker and CoinLedger) connect directly to most exchanges and wallets via API and calculate your gain/loss position automatically. They generate a report you can take to your tax agent or enter directly into myTax. The cost ($50–$250 depending on your transaction volume) is itself a tax-deductible expense as a cost of managing your tax affairs.

The ATO data-matching program — why this matters now

The ATO obtains data from Australian crypto exchanges under its formal data-matching program. This includes the identity details of account holders and transaction data. It is estimated to cover records for up to 1.2 million individuals annually.

What the ATO does with this data:

Cross-references it with lodged tax returns
Identifies individuals who hold crypto accounts but have reported no crypto income or gains
Issues data-matching letters to individuals with apparent discrepancies
Uses the data to support audit selection

If you received a data-matching letter from the ATO, or if you've had crypto activity in 2025-26 that you haven't declared, it is strongly advisable to speak to a registered tax agent before your return is lodged. Voluntary disclosure before an ATO review is treated more favourably than an omission discovered through audit.

Frequently asked questions

Do I have to pay tax on crypto in Australia if I didn't cash out to AUD? Yes — selling is not the only taxable event. Swapping one crypto for another, spending crypto on goods or services, and gifting crypto are all disposal events that trigger CGT. The ATO does not require you to convert to AUD for a taxable event to occur. The gain or loss is calculated using the AUD market value at the time of each disposal.

How is staking income taxed in Australia? Staking rewards are treated as ordinary assessable income, not capital gains. You include the market value of the tokens received (in AUD, on the date you received them) as "other income" in your tax return. Those tokens then have a cost base equal to the income you declared. Any future gain on those tokens when you sell them is a separate CGT event.

What happens if I made a capital loss on crypto? Capital losses on crypto are fully deductible against capital gains in the same year, or carried forward indefinitely to offset future capital gains. They cannot be offset against ordinary income (like your salary). If you have both gains and losses in 2025-26, they net off before the 50% CGT discount is applied.

Does the 50% CGT discount apply to crypto in Australia? Yes — if you held the crypto for more than 12 months before disposal, the 50% CGT discount applies under current rules. From 1 July 2027, the 50% discount is being replaced by a CPI indexation method with a 30% minimum tax floor. Crypto held before 1 July 2027 and sold after will have the gain split between old rules (for pre-2027 accrual) and new rules (for post-2027 accrual).

Does the ATO know about my crypto holdings? The ATO receives transaction data directly from Australian exchanges under a formal data-matching program that covers an estimated 1.2 million accounts annually. This data is cross-referenced with tax returns. The ATO has also signalled it is expanding data collection from DeFi platforms and overseas exchanges where technically feasible. Assume the ATO has at minimum a record of your Australian exchange activity.

Can I claim a deduction for crypto software or tax agent fees? Yes. The cost of crypto tax software used to calculate and report your crypto gains is deductible as a cost of managing your tax affairs. Tax agent fees for preparing your return are also deductible in the year following the year they were charged (e.g., your 2025-26 tax agent fee is deductible in your 2026-27 return).
