Spain plans full rollout of MiCA and DAC8 crypto regulations by 2026

Spain could fully embrace digital currencies in 2026, following a directive from the government to implement two pro-crypto European Union frameworks, MiCA and DAC8. 

Local news publications reported on Wednesday that Spanish authorities are creating a crypto regulatory national framework in line with European standards, Markets in Crypto-Assets Regulation (MiCA), and the entry into force of the Administrative Cooperation Directive, or DAC8.

Together, the two measures will expand the powers of tax authorities over crypto holdings and will add reporting requirements for users and virtual asset service providers (VASP).

MiCA launch in Spain slated for mid-2026

EU-made crypto regulation MiCA became fully applicable in the trading bloc in December 2024, but Spain was among the countries that waited before enforcing its provisions in full. Spanish federal regulators now expect the regulation to be fully deployed in the country by mid-2026, making the decision in early December this year to apply the maximum transitional window allowed under EU law.

The regulation will standardize rules governing the issuance and marketing of crypto assets in tandem with the EU’s demands, including clear classifications for different types of digital assets like utility tokens, security tokens, and stablecoins. Moreover, it will establish uniform compliance requirements for crypto-related service issuers in the country.

Oversight of MiCA in Spain has been assigned to the National Securities Market Commission, known as the CNMV. At the time of writing, more than 60 companies are registered with the watchdog to operate in the digital asset industry, including Cecabank, Banco Bilbao Vizcaya Argentaria, and Renta 4 Banco.

Cryptopolitan reported in mid-December that the CNMV updated its rules to implement MiCA oversight, publishing a Q&A for citizens to understand how the rules work. According to the commission’s notice, the transitional period for companies to become MiCA compliant has been set to July 1, 2026, and only companies that have obtained full MiCA authorization will be permitted to operate in Spain thereafter. 

Crypto tax transparency addressed under DAC8 rules

MiCA may cover how crypto markets and businesses function, but Spain’s second regulatory query is on taxation and transparency. The Administrative Cooperation Directive, or DAC8, was approved by Congress in October 2025 and is scheduled to enter into force on January 1, 2026.

DAC8 says that crypto exchanges and service providers in the EU must automatically send precise information to tax authorities. The data comprises transaction histories, account balances, and user movements, encompassing sales, exchanges, and transfers of assets, which eliminates anonymity in regulated crypto operations.

The government-backed tax enforcement grants the tax administration office, Agencia Tributaria, the power to seize cryptos to settle outstanding tax debts. According to the European Commission, transposing DAC8 into national law in all EU member states could raise an additional 2.4 billion euros in revenue.

Spain’s implementation of DAC8 will see information collected by the Treasury during the 2026 fiscal year begin flowing to tax authorities in 2027. “We will have information on all the movements that have been made during 2026 … It will be almost complete information,” said tax laws consultant José Antonio Bravo Mateu in a recent interview. This information will be much greater than that requested from a bank.”

He continued to say that while conventional financial institutions only report balances above 250,000 euros, watchdogs will keep track of everything in the crypto market, “even an exchange of two euros for a digital coin.”

Spanish parliament approved MiCA and DAC8 in October

The regulatory change to adopt crypto rules in Spain has been bashed by several analysts and economists, who insist Spain is imposing standards with heavier control on the industry compared with other jurisdictions. 

José Luis Cava, author of The Art of Speculating, blasted Spanish policymakers for ignoring the progress made in the West, where a US proposal seeks to allow taxpayers to pay federal taxes in bitcoin without capital gains taxes. He specifically mentioned the “Bitcoin for America Act,” a legislative initiative in which citizens can settle tax obligations directly in BTC.

The Sumar Parliamentary Group held several discussions between October and November, when a minority partner in the governing coalition proposed amendments to the Measures for the Prevention and Fight against Tax Fraud bill. They asked policymakers and proponents of the proposed law to increase tax burdens on crypto earnings.
