As Spain prepares to implement MiCA and DAC8, the European Union’s comprehensive regulations on crypto assets, a radical transformation in the country’s digital currency ecosystem is at hand. The national regulatory framework, prepared in line with the government’s directive, will reshape both the functioning of crypto markets and taxation processes. With these regulations, authorities predict that Spain will establish a fully integrated structure for cryptocurrencies by 2026.
Standardization in Crypto Markets with MiCA
The European Union’s Crypto Asset Markets Regulation (MiCA) came into force throughout the EU in December 2024. However, Spain was among the countries that postponed the implementation, preferring to use the full legal transition period. Spanish regulators announced that MiCA will be fully implemented in the country by mid-2026. This decision is based on the use of the longest transition period allowed by EU legislation.
MiCA introduces clear rules on the issuance, marketing and classification of crypto assets. Different types of digital assets, such as utility tokens, security tokens and stablecoins, will have clear definitions for the first time. At the same time, common compliance standards will be established for crypto service providers. In Spain, control of this process was given to the National Securities Market Commission (CNMV). Currently, more than 60 companies, including BBVA and Renta 4 Banco, are registered with the CNMV to provide digital asset services. CNMV aims to make the process transparent by publishing question-answer documents so that citizens can better understand the new rules.
Tax Transparency and Strict Audit with DAC8
While MiCA focuses on the functioning of markets, the DAC8 regulation highlights transparency in crypto taxation. DAC8, which was passed by the Spanish Parliament in October 2025, will enter into force as of January 1, 2026. Under this regulation, crypto exchanges and service providers will have to automatically report users’ transaction histories, balance information and transfers to tax authorities.
With the powers granted to Agencia Tributaria, it will also be possible to collect unpaid tax debts by seizing crypto assets. The European Commission predicts that the implementation of DAC8 in all EU countries could generate additional tax revenue of approximately 2.4 billion euros annually. The data to be collected in Spain throughout 2026 will be actively used in tax audits starting from 2027. Experts point out that this system will be much more comprehensive than the reporting thresholds in traditional banking.
While these developments are taking place, France has also brought forward a new draft law that similarly increases reporting obligations in crypto transactions, indicating that a period of stricter control has entered Europe. On the other hand, Bitcoin is available in some states in the USA.

As a result, although Spain’s MiCA and DAC8 move aims to ensure trust and transparency in crypto markets, industry representatives argue that these regulations can slow down innovation. Increased reporting burdens, especially for small investors, could largely eliminate the anonymity that makes crypto attractive. Despite this, there is a strong possibility that clear rules will attract institutional investors to the market and contribute to the maturation of the sector in the long term.
