Global CARF
What is CARF?
CARF is the OECD Crypto-Asset Reporting Framework, the global standard for automatic exchange of tax information on crypto-asset transactions.
Updated
Short answer
CARF stands for Crypto-Asset Reporting Framework. It is the OECD global standard for automatic exchange of tax information on reportable crypto-asset transactions between participating jurisdictions.
The core idea is simple. Providers that carry out or facilitate crypto-asset transactions collect information on users and transactions, report it to their domestic tax authority, and tax authorities then exchange that information with other participating jurisdictions.

Why CARF exists
CARF was designed to extend to crypto-assets the international tax-transparency logic already applied to financial accounts under the Common Reporting Standard (CRS).
The OECD considers that crypto-assets can be transferred, held and exchanged without passing through traditional financial intermediaries. CARF therefore aims to recreate a collection point around crypto-asset service providers.
Who must report
CARF targets reporting crypto-asset service providers: parties that, as part of a business activity, provide services enabling crypto-asset transactions for or on behalf of users.
This can include exchange platforms, brokers, custody services, crypto payment services and other intermediaries able to carry out or facilitate reportable transactions.
What CARF covers
CARF covers reporting on crypto-asset activity handled by reporting crypto-asset service providers. The reportable transaction categories include:
- exchanges between crypto-assets and fiat currency;
- exchanges between one crypto-asset and another;
- transfers of crypto-assets, including certain reportable retail payment transactions;
- certain transfers to wallet addresses not associated with an identifiable provider.
CARF is designed for cross-border exchange. A provider reports to its domestic authority, and that authority exchanges the information with other participating jurisdictions when a reportable user is tax-resident there.
What data can be reported?
CARF can require reporting of identity (name, home address, date of birth), tax residence, taxpayer identification numbers, crypto-asset type, transaction type, number of units, total value, acquisitions, disposals and transfers.
CARF and DAC8
CARF is global. DAC8 is the European Union directive applying a similar reporting logic within the EU legal framework. It is the European piece of this global architecture.
DAC8 is not identical to CARF. DAC8 is a binding EU directive that Member States transpose into national law, while CARF is an OECD standard implemented by participating jurisdictions. The legal texts differ, but the shared logic is the same: turn crypto-asset service providers into cross-border tax-collection points, as part of one global move toward automatic crypto-asset tax reporting.
Why it matters
For users, the question is not only European. CARF shows that crypto tax reporting is becoming a global architecture, not just an EU policy.
The risk is the gradual creation of cross-border databases that link identity, tax residence, crypto activity and economic value, with sensitive crypto data circulating between administrations.
Bull Bitcoin’s position
Bull Bitcoin does not oppose taxation. The objection is to mass automatic reporting that can link civil identity, home address, crypto activity and value signals. In crypto, that combination can become a personal-security problem if data leaks, if an insider abuses access or if criminals obtain the database.
The alternative is targeted cooperation: requests tied to identified taxpayers, concrete investigations and proportional safeguards instead of automatic reporting of broad populations.
