Australia Crypto Tax Deadline 2026

The standard ATO self-lodgement deadline for the 2025/26 financial year is 31 October 2026; the next-business-day rule applies when needed. This covers activity from 1 July 2025 to 30 June 2026. Taxpayers on a registered tax agent's client list before the self-lodgement deadline may have a later lodgement date under the ATO's agent program.

Key dates for 2025/26

Australia's financial year runs July to June, which means the lodgement season runs later than most other countries.

• 1 July 2025: The 2025/26 financial year began.
• 30 June 2026: The 2025/26 financial year ended. Disposals after this date fall in 2026/27.
• 31 October 2026: Standard self-lodgement deadline, subject to the ATO next-business-day rule.
• Tax-agent clients: Eligible taxpayers may have a later date under the ATO lodgement program; the exact date depends on the client category and agent arrangements.

ATO data matching for crypto

The ATO operates a data matching program with designated service providers including Australian crypto exchanges. If you traded on an Australian platform, the ATO likely already holds your transaction data and will match it against your lodged return.

The ATO has flagged crypto as a focus area for compliance reviews. Unreported gains or discrepancies between exchange data and reported income trigger review letters. Voluntary and accurate lodgement is always the better outcome than waiting for the ATO to contact you.

Overseas exchanges (Coinbase, Binance, Kraken) are not part of the Australian data matching program, but gains from all exchanges are still taxable in Australia if you are an Australian tax resident. You are responsible for reporting those gains regardless of whether the ATO has the data.

The 50% CGT discount

Capital losses apply before any discount. An eligible Australian-resident individual or trust may then apply a 50% discount to a qualifying gain on an asset held at least 12 months. Companies receive no CGT discount, while complying super funds generally use 33.33%.

• Eligible-individual scenario: A $20,000 qualifying gain remaining after losses may become $10,000 for an eligible Australian-resident individual or trust. This is not the result for a company or complying super fund.
• Capital losses come first. You must apply capital losses to reduce your gross gains before applying the CGT discount. You cannot choose to skip a loss to preserve the discount.
• Short-term assets (held under 12 months) have the full gain included in taxable income. No discount applies.
• The preview flags holding period only. Entity and residency must be confirmed before any discount is applied.

What you need to lodge your return

Accurate crypto tax reporting in Australia requires records going back to your first purchase of each asset.

• Complete exchange CSV - account opening to today. The calculator's disclosed FIFO parcel allocation requires your full acquisition history. The ATO requires supportable cost-base records rather than prescribing universal FIFO.
• Records in AUD. All gains and losses must be reported in Australian dollars. The calculator converts USD and other currencies using daily historical exchange rates.
• CGT discount eligibility. Complete history supplies holding dates, but entity and residency must still be confirmed before selecting a discount rate.
• Staking income records. The ATO generally treats staking rewards as ordinary income at receipt. Record the AUD value of each reward on the date it was received.
• Capital gains schedule. Lodged via myTax (the capital gains section) or through your tax agent. Includes total proceeds, total cost base, and net capital gain or loss for each asset class.

How to calculate your crypto taxes

This calculator uses FIFO across the history provided as a disclosed parcel-allocation assumption. The ATO requires a supportable cost base and records rather than prescribing universal FIFO.

1. Export your transaction history from account opening to today. Download complete CSVs from each exchange - select account opening to today, not just the tax year. This covers all acquisitions that form your cost base pool.
2. Upload to DYOR.tax and select Australia. The calculator applies its disclosed FIFO assumption and flags assets held over 12 months for review of potential CGT-discount eligibility.
3. Add wallet addresses if you used DeFi. On-chain swaps, LP activity, and staking events on Ethereum and other chains are merged with your exchange data. The ATO generally treats token swaps as CGT events.
4. Review your free preview. See short-term gains (no discount), long-term gains (conditional CGT-discount review), staking income, and capital losses - all in AUD before paying anything.
5. Download the full PDF report. It includes a capital gains schedule with per-asset disposal details, holding periods flagged, and an income summary for staking. Enter the figures into myTax or share with your tax agent.

What if you cannot lodge by 31 October 2026?

The standard self-lodgement deadline for 2025/26 is 31 October 2026, with the next-business-day rule applying when needed.

• Check tax-agent eligibility early. Eligible registered-tax-agent clients may have a later date, but the program is not a universal extension and dates vary.
• Contact the ATO or a registered tax agent. If you cannot meet your applicable date, ask about the correct next step for your circumstances.
• Lodge as soon as possible after any missed date. Do not wait for a compliance notice or assume that an agent extension applies automatically.

Common reasons Australian crypto filers miss the deadline

• Assuming ATO data matching does not reach overseas exchanges. Coinbase, Binance, and Kraken are not in the local data matching program, but gains from those platforms are still taxable and your responsibility to report.
• Confusing "capital gains" with "profits made this year." Prior-year purchase prices can affect this year's gain calculations under the selected parcel allocation. Without full historical data, the figures may be incomplete.
• Forgetting staking income. The ATO generally treats staking rewards as ordinary income at receipt. Many filers only track capital gains and miss the income component entirely.
• Not knowing about the tax agent extension. Self-lodgement ends 31 October, but tax agents have later deadlines. Many filers who miss October do not realise they still have time via a registered agent.
