OECD crypto tax reporting to begin data collection in 2026 — 48 countries to start crypto tax data collection ahead of CARF

According to updated information published by the Organisation for Economic Co-operation and Development (OECD), starting in 2027, 48 countries and jurisdictions will begin the automatic exchange of tax information related to cryptocurrencies. However, in practice, data collection has already started in many countries.

As reported by Coinpaper, under the OECD’s Crypto-Asset Reporting Framework (CARF), which is scheduled for global implementation in 2027, participating countries are required to prepare domestic rules and reporting systems in advance. As a result, many authorities expect data collection to begin as early as January 1, 2026, allowing tax authorities to obtain a full year of reportable information before the first CARF exchanges take place.

Currently, 75 jurisdictions have made political commitments to implement CARF. However, the first group of 48 jurisdictions plans to participate in the initial exchange wave in 2027, while others are targeting 2028. This division creates a clear compliance timeline for platforms operating internationally.

To meet the 2027 deadline, participating jurisdictions must complete the development of legislation, technical standards, and exchange agreements in advance. The document emphasizes that an international legal framework for exchanging jurisdictions must be in place by September 2027.

In addition, according to the OECD, 53 jurisdictions have already signed the CARF Multilateral Competent Authority Agreement, which enables tax authorities to securely exchange reporting data. This indicates that the legal infrastructure is progressing faster than operational enforcement.

What data will be collected and how?

Under CARF, reporting obligations fall on crypto-asset service providers, including exchanges, brokers, and certain wallet operators. These entities must identify users and determine their tax residency through self-certification and verification procedures.

Platforms are required to collect standardized identification data relevant to tax reporting. This includes names, addresses, jurisdictions of residence, and tax identification numbers where available. The core objective is to align crypto-asset reporting with existing global tax transparency standards.

CARF also introduces transaction-level reporting. Platforms must report disposals, exchanges, and certain payments involving crypto-assets. The framework notes that retail payment transactions exceeding $50,000 are subject to specific reporting rules, with aggregation applied in certain cases.

As a result, 2026 becomes a critical year for users, as activity on compliant platforms in first-wave jurisdictions may already be tracked for future reporting purposes.

For platforms, the year significantly compresses compliance timelines, as registration, data storage, and reporting systems must be aligned across multiple jurisdictions within tight deadlines.

For tax authorities, CARF aims to close long-standing transparency gaps in crypto markets. The OECD views the framework as a response to the rapid growth of cross-border crypto usage, relying on standardized data rather than country-by-country rules.
