According to ChainCatcher, Spain is set to fully implement two significant cryptocurrency regulatory frameworks by 2026: the European Union's Markets in Crypto-Assets Regulation (MiCA) and the Directive on Administrative Cooperation (DAC8). MiCA will take full effect on July 1, 2026, mandating that all crypto service providers obtain complete authorization to continue operations. Meanwhile, DAC8 will be enforced starting January 1, 2026, requiring exchanges to report users' transactions, balances, and fund flow information to EU tax authorities. Tax experts caution that the Spanish tax agency will have the authority to directly freeze or liquidate users' assets on exchanges to settle tax debts, advising users to consider self-custody solutions, as self-custody wallets are not subject to these reporting requirements.
