In a significant move for the cryptocurrency landscape in Spain, the Sumar parliamentary group has introduced proposed amendments to tax laws that could reshape the regulatory environment for crypto assets. This initiative, announced on November 26, 2025, aims to impose stricter regulations on income and inheritance related to cryptocurrencies, raising concerns among investors. The source notes that these changes could lead to increased compliance costs for businesses operating in the crypto space.
Proposed Legislation on Crypto Taxation
The proposed legislation seeks to shift the taxation of crypto income from the current savings base to the general personal income base. This change could lead to a substantial increase in tax rates for crypto investors, potentially raising the maximum rate from 30% to 47%. Such a hike could deter investment and alter the dynamics of the Spanish crypto market.
Additional Measures in the Bill
In addition to the tax changes, the bill also includes the following measures:
- the introduction of a visual risk indicator for cryptocurrencies
- enhanced regulatory transparency
- better alerts for investors
This measure is designed to create a safer environment for those engaging with digital assets. As the proposal moves forward, its implications for the future of cryptocurrency investment in Spain remain to be seen.
The recent passage of Public Law 11921 has introduced significant changes to the tax framework for 2025, contrasting with the proposed amendments to crypto taxation by the Sumar parliamentary group. For more details, see this article.
