Madrid, Spain – Spanish residents who hold cryptocurrency assets on non-Spanish platforms face a new legal requirement: they must declare these assets by March 31, 2024. This mandate is part of a broader effort by the Spanish government to regulate the burgeoning virtual asset market.

Background of the New Regulation

The Spanish Tax Administration Agency, known as Agencia Tributaria, has introduced form 721, a tax declaration form specifically for virtual assets held abroad. This development, first announced in the Boletín Oficial del Estado on July 29, 2023, marks a significant step in Spain’s approach to cryptocurrency regulation.

Taxpayers, both individual and corporate, are required to declare the amount in their crypto accounts as of December 31, 2023. However, this requirement only applies to those with balances exceeding 50,000 euros. Those holding assets in self-custodied wallets are directed to report through the standard wealth tax form 714.

Escalating Enforcement Efforts

The Agencia Tributaria has intensified its enforcement of crypto asset taxation. In April 2023, it issued 328,000 warning notices to non-compliant taxpayers, a significant increase from the 150,000 warnings in 2022 and just 15,000 in 2021.

Aligning with European Union Regulations

Spain is also aligning its policies with broader European Union (EU) initiatives. The Spanish Ministry of Economy and Digital Transformation reported that the first comprehensive EU crypto framework, the Markets in Crypto-Assets Regulation, will be implemented in Spain by December 2025, ahead of the EU deadline.

Initial Reactions and Implications

The announcement has sparked varied reactions. Advocates argue that this move brings much-needed transparency and regulation to the crypto market, potentially increasing investor confidence. Critics, however, raise concerns about privacy and the practical challenges of enforcing these regulations.

International Perspective

Globally, Spain is not alone in tightening crypto regulations. Countries like the United States, Germany, and South Korea have also introduced or are considering similar measures. This trend reflects a growing recognition of the importance and potential risks of virtual assets.

Future Prospects

Looking ahead, the Spanish government's proactive stance on crypto regulation could position the country as a leader in the emerging digital economy. However, it also faces the challenge of balancing regulation with innovation.


As the deadline approaches, Spanish residents with foreign-held crypto assets must navigate this new regulatory landscape. The success of these measures in achieving their intended goals – increased tax compliance, market stability, and consumer protection – remains to be seen.
