The Sumar faction in Spain's parliament has proposed amendments to increase taxes on cryptocurrency gains. The proposal, submitted to the House of Representatives, aims to include non-financial crypto asset gains in the general income tax base, potentially raising the top tax rate to 47% from the current 30% under the savings tax base. Additionally, a 30% corporate income tax rate is suggested for such gains. The amendment also calls for the Spanish National Securities Market Commission (CNMV) to develop a risk rating system for crypto assets, which must be displayed on investment platforms. Furthermore, it seeks to expand the scope of assets subject to seizure to include all crypto assets, beyond those currently regulated under the EU MiCA framework.
