Crypto Tax in Australia: The 2026 Complete Guide

The Foundational Rule: Crypto Is Property, Not Currency

Everything in Australian crypto tax flows from one ATO position: cryptocurrency is a capital gains tax asset, not money or foreign currency. The ATO treats it like shares, real estate, or a piece of artwork. This single classification determines how every transaction — buy, sell, swap, stake, or spend — is taxed.

For most Australian investors, crypto gains are taxed under the CGT rules. For those who earn crypto through activities like staking, mining, or DeFi, those earnings are ordinary income. The line between the two matters enormously — and most investors misunderstand where it falls.

Every Crypto Transaction Type — and How the ATO Taxes It

The most important thing to understand is that disposal is broader than selling. The ATO counts any of the following as a CGT event:

The 12-Month Holding Rule and the 50% CGT Discount

Timing your crypto disposals around the 12-month mark is one of the most legitimate and impactful tax planning strategies available to Australian crypto investors.

How it works

If you hold a crypto asset for more than 12 continuous months before disposing of it, only 50% of your capital gain is included in your taxable income. The other half is simply disregarded.

Example: You bought 1 ETH on 1 March 2024 for $4,500 AUD. You sell on 15 March 2025 for $7,200 AUD.

• Capital gain: $7,200 - $4,500 = $2,700
• Held over 12 months: Yes (375 days)
• 50% discount applies: $2,700 × 50% = $1,350 taxable
• At 32.5% marginal rate: $438.75 in tax — compared to $877.50 without the discount

What resets the clock

• Every crypto-to-crypto swap resets the 12-month clock for the newly acquired asset
• Wrapping a token (e.g. BTC to WBTC) is likely a disposal — the new wrapped token starts a fresh clock
• Moving between wallets you own does NOT reset the clock — beneficial ownership has not changed

Staking Rewards, DeFi Income, and Airdrops: Taxed as Income

When you earn new crypto rather than disposing of existing crypto, the ATO generally treats the receipt as ordinary income — taxed at your full marginal rate, not as a capital gain eligible for the 50% discount.

Income events and their treatment

• Staking rewards — assessable income at the AUD market value on the date received; future disposal creates a separate CGT event
• Liquidity pool / yield farming income — each periodic reward is income at AUD value on receipt
• Lending interest — income at AUD value when received or credited
• Referral bonuses — income at AUD value when received
• Most airdrops — income at AUD value on receipt; exception for 'initial allocation' airdrops which are taxed on disposal instead
• Mining rewards (commercial scale) — business income if conducted in a business-like manner
• Mining rewards (hobby scale) — generally not income, but gains on disposal are still CGT events

DeFi: The Most Complex Area of Australian Crypto Tax

Decentralised finance introduces tax events that most accountants — and many specialist crypto tax platforms — struggle to classify correctly. The ATO has issued specific guidance on DeFi, but many nuances remain unsettled.

Key DeFi tax positions

Swapping tokens on a DEX (e.g. Uniswap, SushiSwap) — each swap is a CGT event on the disposed asset. The same rule that applies on centralised exchanges applies on decentralised ones.

Providing liquidity to a pool — depositing tokens into a liquidity protocol is likely a disposal of the original tokens and acquisition of the liquidity pool tokens (LP tokens). This is an immediate CGT event. When you withdraw, the return of the underlying tokens may be a further disposal.

Wrapping tokens (e.g. ETH → WETH, BTC → WBTC) — the ATO has stated that wrapping is likely a disposal of the original asset and acquisition of the wrapped asset. This is a contentious position given that both represent the same underlying value, but it is the current ATO guidance.

Yield farming rewards — periodic rewards from DeFi protocols are assessable income at AUD value on receipt.

NFT Tax Treatment: Investor, Creator, or Trader?

The ATO treats NFTs as crypto assets. The applicable tax rules depend on which of three categories describes your activity:

Investor

You buy and hold NFTs with the expectation of capital appreciation, sell occasionally, and do not operate in a business-like manner. Gains and losses are subject to CGT. The 50% discount applies if held over 12 months.

Creator

You create original NFTs and sell them for the first time. The proceeds from the first sale are ordinary income — treated like selling any other product or work of art you created. If you later sell an NFT you previously acquired as an investment, that is a CGT event.

Trader

You buy and sell NFTs at high volume with short hold periods in a business-like manner. The trading stock rules apply — NFTs are treated as inventory, gains are ordinary income, and you cannot access the CGT discount. The ATO is increasingly scrutinising high-volume NFT activity.

Wash Sales: What the ATO Monitors Before 30 June

As the financial year end approaches, crypto investors often consider 'tax loss harvesting' — selling assets that have declined in value to crystallise capital losses that can offset capital gains. This is a legitimate strategy. Wash sales are not.

What is a wash sale?

A wash sale occurs when you sell a crypto asset to generate a capital loss and then immediately (or very shortly after) repurchase the same or substantially identical asset — maintaining the same economic exposure while claiming the tax loss. The arrangement has no genuine commercial purpose beyond obtaining the tax benefit.

The ATO's position

The ATO applies the general anti-avoidance provisions in Part IVA of the Income Tax Assessment Act 1936 to arrangements that are entered into solely or primarily to obtain a tax benefit. Wash sales fall squarely within this. The ATO has stated it actively monitors wash sales in crypto markets, particularly around the 30 June period.

What is legitimate vs not

• Legitimate: Selling crypto that has genuinely declined in value before 30 June to offset capital gains from profitable disposals — and not immediately repurchasing
• Legitimate: Selling a loss-making position and acquiring a different asset with similar exposure (e.g. selling ETH at a loss and buying SOL instead)
• Not legitimate: Selling ETH at a loss on 28 June and repurchasing ETH on 1 July with the sole purpose of claiming the loss while maintaining position
• Not legitimate: Structuring the repurchase through a related party or different wallet address to disguise what is economically the same transaction

Crypto in an SMSF: The Most Tax-Efficient Structure for Large Holdings

For high-income investors with substantial crypto portfolios, the SMSF structure offers the most significant legitimate tax reduction available in Australia. The difference between personal marginal rates and SMSF tax rates on crypto gains is stark.

Requirements for crypto in an SMSF

• The SMSF's investment strategy must explicitly allow for crypto assets — verbal agreements are not sufficient
• Crypto must be held in the SMSF's name, not the individual trustee's personal wallet
• The fund must satisfy the sole purpose test — crypto held for legitimate retirement savings, not personal use
• Crypto assets must be valued at market value for annual financial statements and audit
• The SMSF must have a compliant independent audit each year

Record-Keeping: What the ATO Requires

The ATO requires records of every crypto transaction to be kept for a minimum of five years from when the record was prepared or the transaction completed, whichever is later. For assets that trigger the 12-month CGT discount, the five-year period runs from the date of disposal — meaning records from the original purchase date must be retained.

What to record for each transaction

• Date of transaction
• AUD value at the time of the transaction (critical — not just quantity of crypto)
• Nature of the transaction (purchase, sale, swap, staking reward, airdrop, transfer, etc.)
• Exchange or platform used
• Other party's wallet address where known
• Any fees paid (these can be added to cost base or deducted from proceeds)
• For DeFi: the protocol name and type of activity

Tools National Accounts works with

• Koinly — connects to exchanges via API, imports wallets, generates ATO-compliant reports
• Syla — Australian-built, government-endorsed, supports 500+ exchanges and wallets
• Crypto Tax Calculator (Summ) — strong DeFi and NFT support, accountant-friendly reports

Lost, Stolen, and Inaccessible Crypto: Can You Claim a Loss?

This is one of the most misunderstood areas of crypto tax. The general rule is that a capital loss only crystallises when there is a CGT event — and a CGT event requires a disposal. Simply losing access to a wallet or having crypto stolen does not automatically trigger a disposal.

When you CAN claim a loss

• Exchange collapse where the company enters administration and there is clear evidence the crypto is permanently inaccessible
• Theft where you can provide substantial evidence the crypto is irrecoverable — on-chain transaction records showing the theft, police reports, and evidence of attempts to recover
• Loss of private keys where there is unambiguous evidence the wallet is permanently inaccessible

When the ATO is unlikely to accept the loss

• Crypto on an exchange that has not yet formally wound up — compensation may still be possible
• Losses where the taxpayer cannot provide adequate evidence of the circumstances
• 'Rug pull' situations where tokens still technically exist but have zero value — these may need to be addressed differently
