How Tax Authorities Are Gaining Visibility into Crypto Activity. Crypto-Asset Reporting Framework

The introduction of the Crypto-Asset Reporting Framework on 1 January 2026 marks a major turning point in how crypto activity is monitored and understood by tax authorities. What was once a relatively opaque space is rapidly becoming transparent, especially for users who rely on centralized platforms such as exchanges, brokers, and custodial wallets.

Under the Crypto-Asset Reporting Framework, crypto asset service providers are now required to collect and report detailed information about their users. In practice, this includes any business that facilitates the exchange of crypto assets, whether converting one cryptocurrency into another or turning crypto into fiat currency and back. These providers must gather identifying information about their users, including name, date of birth, address, country of residence, and tax identification number. For companies, business registration details are also required. This effectively removes the anonymity that many users previously associated with crypto, at least when operating through regulated platforms.

In addition to identity data, service providers must report transaction-related information. This includes the type of crypto asset involved, transaction volumes, values at the time of the transaction, and the nature of the activity—whether it is a purchase, sale, exchange, or transfer. While the data is often reported in aggregated form by asset type, it still provides tax authorities with a clear picture of the scale and frequency of a user’s crypto activity.

Wallets play a key role in this system. Custodial wallets—where a platform holds crypto on behalf of the user—are fully within scope and subject to reporting. Transfers from these platforms to other wallets are also recorded. This means that even when users move their assets off-platform, the fact that the transfer occurred is visible. Although non-custodial wallets (those controlled entirely by the user) are harder to monitor directly, the entry and exit points through regulated platforms remain traceable, significantly reducing the effectiveness of using such wallets to avoid visibility.

Another critical aspect of the Crypto-Asset Reporting Framework is the international exchange of information. Data collected by service providers is not confined to one country. It is shared between participating jurisdictions, allowing tax authorities to access information about their residents even if the activity takes place on foreign platforms. This closes a major loophole that previously allowed individuals to operate across borders with minimal oversight.

It is important to understand that the Crypto-Asset Reporting Framework does not calculate tax liabilities. The responsibility for tracking gains, calculating profits, and reporting them accurately still lies entirely with the taxpayer. However, the framework gives tax authorities a powerful tool to compare reported information with actual activity. If discrepancies arise—such as undeclared gains—this can trigger further investigation.

There are also limitations. The framework typically provides aggregated transaction data rather than full transaction histories. From a capital gains perspective, this is not enough to calculate exact tax liabilities, since both acquisition and disposal values for each transaction are required. This means that while authorities gain visibility, taxpayers must still maintain accurate records to ensure correct reporting.

Looking ahead, the direction is clear: more data, more automation, and broader coverage. Future developments are likely to include more detailed reporting requirements, more frequent data exchanges between countries, and tighter integration with tax reporting systems. This could allow tax authorities to automatically cross-check declared income against reported crypto activity with minimal manual intervention.

There is also increasing pressure to extend oversight beyond centralized platforms. While decentralized finance (DeFi) and non-custodial wallets currently present challenges from a regulatory standpoint, they are unlikely to remain outside the scope indefinitely. As technology and regulation evolve, mechanisms may be introduced to capture more of this activity as well.

In practical terms, tax authorities now receive identity data, summaries of crypto transactions, and information about transfers between platforms and wallets. Over time, this data is expected to become more detailed and more systematically used. The broader trend is unmistakable: crypto is moving away from anonymity and toward a level of transparency similar to that of traditional financial systems.
