Australia moves to impose broad crypto tax reporting under OECD CARF, draft law opens consultation

Australia has taken a major step toward mandatory tax transparency for cryptocurrency activity, with Treasury publishing draft legislation to adopt the Organisation for Economic Cooperation and Development Crypto Asset Reporting Framework, known as CARF, alongside related changes to the Common Reporting Standard.

What the draft bill would require

The Treasury Laws Amendment Bill 2026: Tax Information Reporting, released for public consultation in mid October, would require qualifying crypto asset service providers operating in Australia to collect and report standardised identity and transaction data to the Australian Taxation Office. The draft text covers a wide range of activity, including crypto to fiat exchanges, crypto to crypto trades, and transfers into and out of platforms, and it contemplates reporting both domestic aggregate information and records that can be exchanged with foreign tax authorities.

Under the policy timetable set out alongside the draft, the domestic reporting regime would begin ahead of the first international exchanges. Officials expect domestic reporting to start in 2027, with the first cross border exchanges of reported crypto data between the ATO and partner tax authorities occurring from 2028, once bilateral and multilateral arrangements are in place.

Who would be in scope

The exposure draft identifies typical in scope entities as centralised exchanges, broker platforms, and certain custodial wallet providers. It also flags that some operators, such as noncustodial wallet providers and decentralised finance protocols, may be outside the direct reporting perimeter unless they act in ways that give them custody or control of users keys or assets.

The draft requires providers to collect customers tax residence and taxpayer identification details, verify identities, and maintain records of reportable transactions. That will mean Australian platforms need to upgrade onboarding, know your customer and data systems to meet the specified CARF data schema, while multinational exchanges will face parallel obligations in other jurisdictions adopting the same standard.

Timing and consultations

Treasury opened a formal consultation period on the draft legislation, inviting submissions from industry and stakeholders. The consultation timetable published with the exposure draft sets short deadlines for comment and aims to give firms time to prepare for technical changes to reporting formats and data collection systems ahead of the proposed 2027 start date for domestic reporting.

Tax and law firms that advise financial institutions and crypto businesses note that the implementation window is tight. Firms emphasise that reporting platforms should begin technical work now to be ready for required XML reporting formats and to manage identity verification at scale. The Australian Taxation Office has already issued separate technical updates earlier in October about related reporting schema changes for other international exchange standards, underscoring the systems work that will be necessary.

Why this matters for Australian users and platforms

For Australian retail crypto users, the draft does not change the underlying tax treatment of crypto disposals, which remain subject to capital gains tax when relevant. What will change is the scale and granularity of information the ATO can obtain automatically from platforms both inside Australia and from foreign exchanges that report under CARF.

That means private transactions, off exchange transfers, and cross platform activity that previously relied on manual ATO data matching or audits could be more readily visible to revenue authorities through standardized annual reports. Platforms will be required to retain and verify identity data for customers, reducing anonymity for reportable flows.

Industry reaction and open questions

Industry bodies, exchanges and legal advisers welcomed clarity on the shape of future rules but urged careful rule drafting, particularly on scope definitions and the treatment of decentralised services. Primary concerns raised in early commentary include the boundaries for noncustodial wallets, the administrative cost burden on smaller Australian platforms, and the potential for duplicative reporting when a multinational platform operates across multiple jurisdictions.

Privacy and data security advocates also cautioned that the legislation will create a large trove of sensitive personal and financial data that must be protected. Technical briefs accompanying the draft encourage providers to follow best practice on data minimisation and information security, but the bill leaves substantial detail to prospective subordinate instruments and ATO technical guidance, which remain subject to consultation.

Next steps

The Treasury consultation closes according to the timetable published with the exposure draft, after which the government will consider submissions and may amend the drafting ahead of introduction to Parliament. If the bill proceeds on the current plan, platforms would need to complete technical readiness work this year and into 2027 to meet the domestic filing requirements, while the ATO seeks multilateral agreements to begin exchanging reported crypto data internationally from 2028.

The policy represents Australia aligning with an expanding global consensus on crypto tax transparency, which aims to reduce cross border tax evasion but will also reshape compliance and data practices for the domestic crypto sector.
