EU Details DAC8 Crypto Tax Reporting Rules Ahead of 2027 Information Sharing

European Union tax authorities have outlined reporting and due-diligence obligations under the eighth Directive on Administrative Cooperation (DAC8) ¹. Adopted by EU member states on Oct. 17, 2023, the directive requires Reporting Crypto-Asset Service Providers (RCASPs) to collect transaction data on both resident and non-resident clients ¹. While provisions took effect on Jan. 1, 2026, after a transposition deadline of Dec. 31, 2025, authorities will execute their first cross-border automated tax exchanges by Sept. 30, 2027 ¹.

Under the framework, RCASPs must submit annual transaction records to their local national tax bodies during the calendar year immediately following the reporting period ¹. For non-resident investors, member states are mandated to exchange this data with the tax agency of the user's home EU country within nine months after the close of the reporting year ¹. The regulatory rules mirror the Organisation for Economic Co-operation and Development's (OECD) Crypto-Asset Reporting Framework (CARF), which provides interpretative commentary and operational guidance where aligned ¹.

Scope and Coverage

The reporting requirements build on the definitions outlined in the Markets in Crypto-Assets (MiCA) regulation ¹. The scope covers stablecoins, e-money tokens, decentralized digital assets, and specific non-fungible tokens (NFTs) ¹. The European Commission noted that the decentralized architecture of crypto-assets previously hindered tax compliance, necessitating administrative cooperation to track cross-border income and capital gains ¹.

National authorities within the bloc continue adjusting their domestic tax approaches alongside these transparency mechanisms, reminiscent of discussions seen when Greece proposes 10% flat tax on crypto capital gains and staking yields. Broader reporting mandates parallel shifts occurring across European jurisdictions, including standard procedures documented around crypto taxes in the UK. At the time of writing, major digital assets traded slightly down over the previous 24 hours, with $BTC at $82,579 and $ETH at $2,549.
