Spain is reviewing a proposal that would raise the tax rate on personal cryptocurrency gains to as high as 47 percent. The plan was introduced by Sumar, one of the parties in the governing coalition. It would move crypto profits from the savings income category into the general income bracket, where the top rate reaches 47 percent. Today, the highest tax on savings income sits around 30 percent, so this change would be a significant jump for frequent traders and high earners.

Corporate Taxes Stay Where They Are

For companies, the picture is more familiar. Corporate gains from crypto would continue to be taxed at 30 percent. That is consistent with Spain’s standard corporate tax rate. The personal income change is the part that is drawing attention from investors and industry professionals.

Extra Investor Protection Measures

Sumar’s amendment package includes more than tax changes. One proposal would require the CNMV to introduce a traffic light style risk label for crypto products offered on investment platforms. The goal is to make the risk level of each product clearer for retail investors before they buy or trade.

The package also includes language that classifies all cryptocurrencies as assets that could be seized in enforcement actions. Specialists have raised concerns about how this would work in practice when assets sit in self-custody and cannot be accessed like traditional financial instruments.

Expert Pushback and Public Reaction

Spanish tax professionals and crypto industry voices have been critical of the proposed top rate. Many warn that a 47 percent ceiling could reduce local activity or drive investors toward jurisdictions with more predictable or lower tax treatment. Several experts also questioned the feasibility of enforcing seizure rules for self-custodied assets.

The Legislative Status Today

The Spanish government has not formally endorsed the 47 percent rate. The proposal currently sits within parliamentary discussions and would need wider political support before advancing. For now, it remains a trigger for debate rather than a confirmed change to the tax code.
