EU DAC8 Crypto Tax Reporting Rules Effective From 1 January 2026 Across Member States

The European Union's DAC8 directive entered into force on January 1, 2026, obliging custodial crypto-asset service providers to submit user identity data, tax IDs, and transaction histories to national tax authorities. The regime applies to crypto-to-fiat trades, crypto-to-crypto swaps, and transfers from custodial platforms to external wallets, while non-custodial wallets remain outside the reporting scope. Estimates indicate DAC8 could add around €1.7 billion in annual tax revenue, alongside substantial one-off and recurring compliance costs for the industry.
