A new era of transparency for the cryptocurrency industry officially began this week, as strict new reporting rules came into force across nearly 50 jurisdictions.

The initiative, known as the Crypto-Asset Reporting Framework (CARF), is designed to close the loop on tax evasion by ensuring digital assets are subject to the same level of scrutiny as traditional bank accounts.

Here is an explanation of what CARF is, how it works, and specifically what it means for crypto investors in the Philippines.

What is CARF

The Crypto-Asset Reporting Framework (CARF) is a global standard developed by the Organisation for Economic Co-operation and Development (OECD).

In layman’s terms, CARF is a massive information-sharing network for tax authorities.

For decades, banks have shared customer data across borders to prevent wealthy individuals from hiding money offshore. However, cryptocurrencies previously fell outside these rules, allowing investors to trade digital assets on foreign platforms without their home tax authority knowing.

CARF closes this loophole. It standardizes how crypto exchanges, wallet providers, and brokers collect information about their users and mandates that this data be automatically shared with tax agencies worldwide.

What Happens When CARF is Implemented?

For the “First Wave” of countries, the rules took effect on January 1, 2026.

1. Data Collection Begins Immediately

Crypto service providers (exchanges like Coinbase or local platforms) operating in participating countries must now collect detailed “due diligence” information. They are required to record:

• The identity of the crypto owner.
• Their tax residency.
• The total value of assets sold or exchanged.
• Any profits made.

2. Automatic Sharing (Starting 2027)

The data collected in 2026 will be packaged and automatically sent to the tax authorities of the user’s home country in 2027.

3. The Result

If you are a tax resident of a participating country (for example, the U.K) but you use a crypto exchange based in the Cayman Islands, the Cayman exchange will automatically send your trading history to the UK’s tax authority (HMRC).

Focus: What this means for the Philippines

While the Philippines is not part of the initial “First Wave” implementing rules this week, it has committed to the “Second Wave,” with data exchanges scheduled to commence by 2028.

This timeline establishes a new regulatory environment for Filipino investors and the Bureau of Internal Revenue (BIR):

1. Automated Cross-Border Reporting

Currently, Filipino investors utilizing international platforms (such as those in Singapore, Hong Kong, or the Caribbean) operate in a landscape where data sharing is often manual or request-based.

Under CARF, this process becomes automatic.

By 2028, it is expected that the BIR will systematically receive reports from foreign tax authorities detailing crypto transactions attributed to Filipino tax residents. This will align digital assets with traditional banking standards.

2. Regional Regulatory Alignment

With key financial hubs like Singapore, Hong Kong, Malaysia, and Thailand also committing to the 2028 timeline, the region is moving toward a standardized reporting ecosystem.

This means compliance requirements will be uniform for Filipinos regardless of whether they transact on local or regional platforms.

3. Data-Driven Tax Administration

Rather than relying primarily on voluntary disclosures or individual audits to identify taxable events, the tax bureau will gain access to a standardized stream of global data. This allows the bureau to verify declarations more efficiently against international records and thus reduce the administrative burden on both the state and compliant taxpayers.

4. Transition and Compliance Period

The timeline provides a two-year runway for the industry to adapt.

This window allows the BIR to upgrade its IT infrastructure to process bulk data exchanges, while giving investors and institutions time to align their record-keeping with the new global reporting standards before full implementation in 2028.

Global Implementation Timeline

As of December 4, 2025, 76 jurisdictions have committed to the framework, split into three waves.
