The parliamentary group Sumar in Spain has tabled a legislative reform proposal aimed at significantly increasing the tax burden on crypto gains. The plan would move cryptocurrency capital-gains from the current “savings tax base,” where rates are capped around 30 %, into the “general tax base,” where marginal tax rates can reach up to 47 %. It also calls for a flat 30 % corporate tax rate on crypto profits.
What the proposal would change
According to media reports sourced via Phemex, the Sumar proposal includes several key shifts:
- Moving personal crypto-asset gains currently taxed under the “savings base” (Base Imponible del Ahorro) into the “general base” (Base Imponible General). Under the general base, high-income taxpayers face rates up to 47 %.
- Introducing a specific corporate tax rate of 30 % on companies generating profits from crypto-asset activities or holdings.
- Additional proposed measures: the plan reportedly includes requiring crypto platforms to display risk ratings, and expanding asset-seizure powers to cover more digital asset holdings.
Why it matters
- Increased tax burden for individual crypto users – Under current Spanish rules, many crypto trades fall under “savings income” tax, which has lower brackets (for example, up to 28 %). Moving them into the general base could upgrade the rate to the maximum marginal levels for high earners.
- Corporate exposure – A 30 % tax rate on corporate crypto profits may impact firms with substantial crypto holdings or operations, such as crypto trading, staking or treasury management activities.
- Broader regulatory intent – The proposal hints at more than just tax hikes; regulators also appear prepared to impose reporting requirements and supervisory risk frameworks on crypto platforms and users.
- Investor and market implications – Spain is a significant European economy with a large crypto-active population. Tax policy shifts may affect investor behaviour, platform practices and regional competitiveness for crypto firms.
Current tax regime in Spain (baseline)
- Gains from crypto disposals for individuals have traditionally been treated as savings income (capital gains) and taxed at progressive rates up to about 28 % for large gains.
- Income that is not capital gains (e.g., mining, staking, payment in crypto) may fall under the general income base and face higher marginal rates (in some cases up to 47 %).
- Corporate tax on crypto profits generally follows standard corporate income tax rules, but the new proposal seeks to make crypto-profit taxation more explicit.
Reactions and potential challenges
- Crypto community push-back – The proposed hike may meet resistance from individual investors and platforms, who may argue it risks pushing activity to other jurisdictions with lighter tax burdens.
- Implementation complexity – Shifting crypto gains to the general tax base would require re-classification of many activities and may lead to transitional issues. Accurate cost-basis tracking, categorisation of trades vs. income, and clarity on when the higher tax applies will be needed.
- Regulatory coordination – Spain will need to align its tax and regulatory frameworks (e.g., reporting obligations, anti-money-laundering rules) with these reforms to avoid enforcement bottlenecks.
- Economic competitiveness – As crypto-friendly policies compete across Europe, Spain may face questions about whether such high taxation discourages innovation or encourages capital flight.
What to watch next
- Parliamentary progress: How quickly the Sumar proposal moves through Spain’s legislative process — committee reviews, amendments, vote schedules.
- Official drafts and fiscal estimates: Whether Spain’s Ministry of Finance publishes detailed fiscal cost/benefit analyses and clarifies which transactions are affected.
- Clarifications for individuals: Will authorities issue guidance on what constitutes “general income” vs. “savings income” in crypto contexts (e.g., staking rewards, airdrops, trading)?
- Corporate reporting rules: The rollout of the 30 % corporate crypto-profit tax and how companies adapt (accounting standards, disclosures).
- Cross-border effects: Responses from EU institutions and how Spain’s tax reform fits into broader EU crypto tax policy and regulatory alignment.
Bottom line: The Sumar parliamentary group’s proposal to raise taxes on crypto gains — moving them into higher tax brackets of up to 47 % and imposing a 30 % corporate rate — marks a major potential shift in Spain’s crypto-tax landscape. Investors, platforms and companies active in the Spanish market should monitor developments closely and prepare for policy changes.
