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](https://basisdesk.news/news/greece-proposes-ten-percent-crypto-tax-capital-gains). Broader reporting mandates parallel shifts occurring across European jurisdictions, including standard procedures documented around [crypto taxes in the UK](https://basisdesk.news/news/crypto-taxes-uk-basics). 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. ## FAQ **What is DAC8?** DAC8 is an EU directive establishing reporting rules and administrative cooperation for tax authorities regarding crypto-asset transactions. **When does reporting begin under DAC8?** Provisions apply starting Jan. 1, 2026, with the first automatic data exchanges among EU member states taking place by Sept. 30, 2027. **Which assets are subject to DAC8?** The directive applies to assets defined under MiCA, decentralized crypto-assets, stablecoins, e-money tokens, and certain NFTs. ## Sources 1.
