The EU Will Begin Tracking Crypto Transactions

Starting January 1, 2026, tax authorities across the European Union will begin implementing a new regime for monitoring cryptocurrency transactions under the DAC8 directive and the CARF (Crypto-Asset Reporting Framework) standard developed by the OECD. This means that platforms will be required to share user data with tax authorities, with cross-border information exchange between countries planned to start as early as 2027.

The new CARF reporting standard expands traditional financial information exchange and includes data on crypto activities such as exchanges, transfers, and digital asset transactions . Service providers—including crypto exchanges, brokers, and custodial wallets—will be required to collect and report transaction data and clients’ tax residency information. This data will be automatically transmitted to the tax authorities of the countries where users reside.

As a result, from 2026 onward, crypto operations in the EU will no longer exist in a “grey zone”: tax authorities will gain significantly more visibility into fund flows and will be able to verify whether tax declarations align with users’ actual transactions and platform activity.

However, it is important to understand that these changes apply only to platforms that are required to collect user data—centralized platforms, exchange services, and custodial providers. Many services, especially self-custody wallets where users retain full control over their private keys, are not subject to direct data sharing with tax authorities.

This is particularly relevant for Marsses users. Our platform offers staking models that do not require the transfer of personal data to third parties, allowing users to maintain a high level of privacy . Staking through Marsses remains an accessible, transparent, and attractive passive income tool even as market regulation becomes more stringent.

Investors seeking to optimize their strategies should take the new requirements into account, remain mindful of their tax obligations, and use tools that combine reliability, profitability, and confidentiality.

Therefore, even amid increasing regulatory oversight, a well-considered approach—especially mechanisms such as staking through Marsses—can continue to serve as a stable foundation for long-term investment and passive income .
