What is CARF?

The Crypto-Asset Reporting Framework is an OECD standard that requires businesses operating in the crypto-asset space to collect, verify, and report tax-relevant information about their customers' transactions. That information is then automatically exchanged between participating tax authorities around the world, in the same way CRS works for financial accounts.

CARF was approved by the OECD in 2023. In 2024, the OECD published the XML schema, user guide, and detailed interpretative guidance. Jurisdictions are now legislating domestic implementation, with first information exchanges expected in 2027.

Scope

Broad obligation

CARF applies to Crypto-Asset Service Providers (CASPs) and other intermediaries that facilitate exchanges, transfers, and custody of crypto-assets. Scope is deliberately wide, covering exchanges, custodians, brokers, and certain payment processors.

What must be reported

Customer and transaction data

Businesses must identify reportable customers, conduct due diligence to confirm tax residency, and report transaction-level data including crypto-asset type, volume, and value across exchanges for fiat, exchanges between crypto-assets, and transfers.

Why it matters

Automatic exchange

Reported data is exchanged automatically between tax authorities in participating jurisdictions. Non-compliance carries regulatory and reputational risk. With first exchanges expected in 2027, operational readiness cannot be left to the last moment.

Key milestones

The CARF implementation calendar is moving quickly. Understanding the timeline is the first step to planning your compliance programme.

  1. CARF approved

    The OECD formally approved the Crypto-Asset Reporting Framework as a new global standard for automatic exchange of tax information relating to crypto-assets.

  2. Technical standards published

    The OECD released the CARF XML schema, user guide, and interpretative guidance, giving businesses and developers the technical foundation needed to build reporting systems.

  3. Preparation window: act now

    Firms need to assess their obligations, implement due diligence procedures, organise transaction data, and establish reporting workflows. Domestic legislation is in progress across multiple jurisdictions.

  4. First exchanges expected

    The first automatic exchanges of CARF information between tax authorities are expected to commence. Businesses in participating jurisdictions must be operationally ready before this date.

Implementation timelines and domestic rules may vary by jurisdiction. Businesses should monitor local legislative developments and seek appropriate professional advice.

What CARF.digital will do

CARF.digital is designed to handle the operational complexity of CARF compliance, from initial data collection through to reporting-ready output. Built for teams that need a structured, auditable process, not a spreadsheet workaround.

Structured data capture

Collect and organise the customer and entity information required under CARF, including identification data, tax residency, and self-certification, in a structured, schema-aligned format from the outset.

Due diligence workflows

Step-by-step workflows to guide teams through CARF due diligence requirements: determining reportability, identifying controlling persons, and documenting the basis for each determination.

Reportable person and entity management

Maintain a clear, up-to-date record of which customers and entities are reportable under CARF, across which jurisdictions, with the supporting documentation to back every decision.

Transaction data organisation

Structure and validate the transaction data required for CARF reporting, covering exchanges for fiat, crypto-to-crypto exchanges, and transfers, matched to the OECD's schema requirements.

Review and audit trail

Every determination, document, and data point is logged with timestamps and user attribution. Give your compliance team and your regulators a clear, reviewable record of your CARF process.

Reporting readiness and output preparation

Move from organised data to report-ready output, structured to align with CARF XML schema requirements, minimising manual effort and reducing the risk of errors in the filing process.

Who it's for

CARF creates obligations across a broad range of businesses, not just the largest crypto exchanges. If your business facilitates or intermediates crypto-asset transactions, custody, or exchange, you likely need to understand your CARF position.

Crypto exchanges & custodians

Centralised and decentralised platforms facilitating crypto-asset trading, exchange, and custody.

Brokers & dealers

Businesses executing or arranging crypto-asset transactions on behalf of clients.

Fintechs & payment firms

Payment processors and fintech platforms that facilitate crypto-asset transfers or conversions.

Professional service firms

Accountants, lawyers, and advisers supporting clients with CARF classification and compliance.

Family offices & private wealth

Structures with direct or indirect crypto-asset holdings that may trigger CARF reporting obligations.

TCSPs & fund administrators

Trust and company service providers, fund administrators, and fiduciaries managing entities with crypto exposure.

Compliance & RegTech teams

In-house compliance functions and RegTech operators building CARF infrastructure for themselves or their clients.

Other service providers

Any business acting as an intermediary in crypto-asset transactions that falls within the CARF definition of a Reporting Crypto-Asset Service Provider.

Why CARF.digital

We are not entering this space cold. CARF.digital is built on direct operational experience with international tax reporting standards, and on partnerships with organisations already working at the intersection of regulatory compliance and crypto-asset intelligence.

From the team behind Classifi

CARF.digital is built by the same team that developed Classifi, the software used by compliance professionals for CRS and FATCA entity classification. We understand how reporting frameworks work in practice: the edge cases, the documentation requirements, and the operational pressures compliance teams face.

Deep experience in CRS and FATCA

CRS and FATCA set the template for CARF. Our background in building structured classification and due diligence workflows for those frameworks means we are translating proven methodology rather than starting from scratch.

In partnership with C-Thru

CARF.digital is developed in partnership with C-Thru, combining compliance framework expertise with specialist knowledge in the crypto-asset reporting space. Together, we are building something that reflects how real compliance processes work.

Built for operational use

CARF.digital is designed to be used by compliance teams, not just read about at conferences. Every feature is shaped around the actual workflow of identifying obligations, collecting data, reviewing determinations, and producing output.
