The MiCA regulation will require all crypto service providers to obtain full authorization by July 1, 2026, or cease operations. Meanwhile, DAC8 will require exchanges to report users’ transactions and balances to EU tax authorities starting January 1, 2026. These changes are expected to impact a range of crypto activities, from exchanges to wallet services.
Spain’s Transitional Period for Crypto Service Providers
The Spanish government has adopted the EU’s maximum transitional period for MiCA compliance, giving crypto service providers until July 2026 to secure full authorization. This transitional period is meant to give businesses time to adapt to the new regulations.
During this time, companies that were already registered with Spain’s Bank of Spain before December 30, 2024, can continue their operations. This includes services like currency exchange and wallet custody.

However, businesses offering services like portfolio management or investment advice must also prove they were operational before December 30, 2024, to use the transitional period. The Bank of Spain has ceased accepting new registrations after this date, with the CNMV (National Securities Market Commission) now overseeing crypto business regulations in Spain.

What MiCA and DAC8 Mean for Crypto Exchanges
MiCA and DAC8 are significant because they require exchanges to comply with a broad set of requirements, including providing detailed reports of user activity. DAC8, which takes effect in January 2026, mandates that exchanges report user transactions, balances, and fund flows to EU tax authorities. Experts warn that the Spanish tax agency will be able to freeze or liquidate assets to settle tax debts, highlighting the need for crypto users to be cautious.
Meanwhile, MiCA’s July 2026 enforcement will ensure that only licensed firms can offer services across the EU. The regulation will affect a wide range of crypto services, including wallet providers, exchanges, and crypto asset managers. The CNMV has already begun accepting MiCA authorization applications for Spanish crypto firms, with only a few, including BBVA, currently licensed.
Registration and Compliance Process for Crypto Firms
The CNMV has provided guidance on the application process for crypto service providers looking to comply with MiCA. The process requires companies to submit over 100 pages of detailed information about their operations, governance, and risk management practices. However, some firms that are already regulated under EU laws, such as banks or e-money institutions, can follow a simplified notification procedure instead of going through full authorization.
In addition, the CNMV has clarified that companies based in other EU countries, even those using transitional periods, cannot automatically provide services to Spanish customers unless they also meet Spain’s transitional rules. This ensures that businesses follow specific national regulations until they obtain full MiCA authorization.
