Australian crypto tax filing 2026: a step-by-step ATO and myTax guide

An Australian return lodged in 2026 generally covers the income year from 1 July 2025 to 30 June 2026, not the 2026 calendar year. Crypto investors then need to separate capital gains and losses from staking or other ordinary income, business activity and derivative review items. The detailed transaction schedule supports the figures entered in myTax; it does not replace the complete return. This guide follows ATO material and explains what CoinTaxReporting can calculate, what must remain reviewable and which evidence to retain.

Step 1: select the correct Australian income year

Australia's standard individual income year runs from 1 July to 30 June. The year is normally labelled by its ending year. Therefore, income year 2025-26 runs from 1 July 2025 through 30 June 2026. In CoinTaxReporting, selecting Australia and report year 2026 should represent that ending-year period; selecting 2025 represents 1 July 2024 through 30 June 2025.

This distinction matters when an exchange exports calendar-year CSV files. A January 2026 disposal belongs to income year 2025-26, while an August 2026 disposal belongs to 2026-27. Import the complete history, but verify that the report totals use only the correct period.

A registered tax agent may have a different lodgment schedule. There is no universal "30 November tax-agent deadline" for every client. Engage an agent before the relevant cut-off and confirm the date for the taxpayer's account.

Step 2: gather and reconcile all crypto records

Do not start with the taxable total shown by one exchange. The cost base of a disposal can originate on another exchange, in an earlier income year or in a self-custody wallet. Import every account needed to trace ownership and acquisition history, including inactive platforms and opening balances.

• exchange CSV and account statements;
• wallet addresses, transaction hashes and ownership evidence;
• acquisition and disposal dates, quantities and AUD values;
• fees, commissions, gas and other eligible costs;
• staking, mining, airdrop and service-reward records;
• derivative statements showing realised P&L and contract details;
• evidence for gifts, lost access, scams or personal-use claims;
• prior-year capital losses and prior workpapers.

Reconcile each asset: opening quantity plus acquisitions and receipts, less disposals and outgoing transfers, should explain the closing quantity. Match own-wallet transfers before calculating disposals. If an acquisition cannot be reconstructed, mark the sale as not computable; do not call a zero placeholder a verified cost base.

The ATO requires Australian-dollar values at transaction time. Keep the price or exchange-rate source and timestamp. A USD or stablecoin quote still needs a consistent AUD conversion. The Australian crypto CGT guide explains proceeds, cost base and the loss-before-discount sequence.

Step 3: separate CGT, ordinary income, business and derivatives

For an investor, selling crypto for fiat, swapping it for another crypto asset, spending it or gifting it can trigger a CGT event. Buying with AUD and moving assets between wallets under the same beneficial ownership are generally not disposals, although associated fees still require analysis. The narrow personal-use asset rules are not a general AUD 10,000 crypto exemption.

An eligible Australian resident individual may receive a 50% CGT discount on a qualifying capital gain after holding the asset for at least 12 months. Apply eligible current and carried-forward capital losses before the discount. The discount is not available merely because a derivative position lasted 12 months, and it is not applied to ordinary reward income or business trading profit.

Use the actual facts to choose investor or business status. The Australian trading-versus-investing guide lists the relevant conduct. A report profile is a documented conclusion, not a tax-minimisation election.

Step 4: transfer reviewed totals into myTax

Personalise myTax so the required capital gains or losses and income sections are displayed. For investment disposals, use the detailed crypto workpaper to support total current-year capital gains, net capital gain and any net capital loss carried forward. myTax may show an indicator or pre-fill information from data matching, but the taxpayer remains responsible for checking all activity and adding anything absent.

1. Confirm residency, identity and the 2025-26 return period.
2. Complete salary, interest, deductions and all non-crypto parts of the return.
3. Enter the reviewed capital-gain totals and carried-forward loss information.
4. Enter staking, airdrop, mining or service income in the applicable income route.
5. Use the business section where the taxpayer actually carries on a business.
6. Resolve derivative and DeFi review items rather than burying them in spot CGT.
7. Compare myTax totals with the final report and save a filing copy.

A detailed disposal schedule is not the same as a US Schedule D, and an Australian individual does not file a US form merely because tax software calls its export "Schedule D." Use Australian return labels and ATO instructions. CoinTaxReporting produces calculation and review workpapers; it does not submit the return or calculate every personal offset, Medicare item, foreign-income issue or final amount payable.

Step 5: review common Australian crypto filing errors

• Wrong period: using January to December instead of July to June.
• Cash-only reporting: omitting crypto-to-crypto disposals and spending.
• Missing history: treating an exchange deposit as zero-basis income or sale.
• Average entry confusion: copying a derivatives dashboard average into an investor CGT cost base.
• Premature discount: applying 50% before capital losses or to an ineligible taxpayer or event.
• Reward double count: recording a pool accrual and the later wallet payout as two receipts.
• Pre-fill reliance: assuming ATO data matching contains every wallet and correct basis.
• Personal-use overclaim: treating a long-held investment portfolio as exempt because its value is small.

The ATO's crypto data-matching activity is a reason to reconcile, not a reason to invent certainty. Differences can arise from transfers, fees, timing, incomplete exchange data or beneficial ownership. Preserve the explanation for each adjustment.

Step 6: lodge on time and retain the evidence

Individuals lodging their own return generally have a 31 October deadline after the income year ends, subject to the taxpayer's circumstances and current ATO information. Agent dates vary. Check the due date in ATO online services or with the registered agent rather than relying only on a blog post.

The ATO says crypto records should generally be kept for five years from the later of the relevant listed times. Longer practical retention may be necessary for assets still held, carried-forward losses, amended assessments or records reused in later calculations. Export exchange history regularly and before closing an account.

A defensible filing pack contains the lodged return, notice of assessment, transaction-level workpaper, review log, source exports, wallet evidence, AUD valuation method and prior-year loss schedule. Keep corrections versioned so a reviewer can reproduce the final totals.

CoinTaxReporting users can generate the Australian report after reconciliation and then compare the report's income-year label, profile, currency and totals with myTax. See the Australian crypto-loss guide before applying carried-forward losses.
