Spain's left-wing political group Sumar, part of the governing coalition, has sparked controversy with a bold proposal to overhaul crypto taxation. The plan includes raising capital gains taxes on crypto to 47%, classifying digital assets as "seizable property," and introducing mandatory risk warnings on exchanges. Critics argue the measures are technically unfeasible and could drive investors out of Spain. Meanwhile, projects like Best Wallet aim to protect crypto privacy amid increasing regulatory scrutiny. Here’s a deep dive into the implications of this aggressive fiscal reform.
Why Is Spain Targeting Crypto with a 47% Tax?
The heart of Sumar’s proposal is reclassifying crypto gains from "non-financial assets" to taxable income under Spain’s progressive tax bracket, where rates can soar to 47%. Currently, crypto profits fall under the "savings tax" category, capped at 30%. For businesses, the plan mandates a flat 30% tax on crypto-related profits. This MOVE aligns with Sumar’s skepticism toward decentralized finance—a stance that could make Spain one of Europe’s strictest crypto tax regimes. As of 2025, Spanish tax authorities have already ramped up enforcement, sending 620,000 crypto-related tax notices in 2023 alone (Source: Spanish Treasury).
Best Wallet: A Shield Against Regulatory Overreach?

Amid the crackdown, projects like Best Wallet are gaining traction. The platform offers private, self-custody solutions to keep crypto holdings "out of regulators’ sight." Its launch timing is no coincidence—as centralized exchanges face tighter controls, tools prioritizing privacy could become essential. However, the BTCC team notes that while self-custody mitigates seizure risks, it doesn’t exempt users from tax obligations. "The real battle is about financial autonomy," says a BTCC analyst. "But tax authorities globally are getting smarter at tracking on-chain activity."
The "Traffic Light" Risk Warning: Consumer Protection or Overreach?
Sumar’s proposal includes a novel "risk traffic light" system, requiring exchanges to display color-coded warnings (similar to food nutrition labels) for each crypto asset. While framed as consumer protection, critics call it paternalistic. "This assumes investors can’t DYOR," quips economist José Antonio Bravo Mateu. The plan also clashes with MiCA regulations, which bar regulated custodians from holding certain tokens—a contradiction Spain hasn’t resolved.
Can Crypto Assets Really Be Seized?
The most contentious idea is treating cryptocurrencies as "seizable property" like bank accounts or cars. Legal expert Cris Carrascosa highlights the absurdity: "You can’t repo a Bitcoin." Decentralized assets lack physical or centralized control points, making seizures impractical. Even under MiCA, regulated entities can’t custody many tokens, leaving enforcement gaps. This hasn’t stopped Spanish authorities from trying—328,000 tax warnings went out in 2022, doubling by 2023 (Source: Coinmarketcap).
Is Spain Becoming Hostile to Crypto?
Two tax inspectors, Juan Faus and José María Gentil, recently proposed atax framework allowing FIFO or weighted-average accounting methods. Their approach contrasts sharply with Sumar’s crackdown, revealing a policy rift. "Paradoxically, Spain could both chase away investors and innovate tax policy simultaneously," observes the BTCC team. With other EU nations like Germany taxing crypto more lightly, Spain risks a brain drain if its reforms pass.
What’s Next for Crypto in Spain?
The proposal faces legislative hurdles, but its symbolism is clear: Spain’s left-wing sees crypto as a loophole to close, not an innovation to nurture. Meanwhile, tools like Best Wallet and offshore options may flourish as workarounds. As of November 2025, the debate rages—with crypto’s future in Spain hanging in the balance.
FAQs
How high is Spain’s current crypto tax?
Capital gains from crypto are taxed at up to 30% under the "savings tax" category. Sumar’s proposal WOULD shift this to income tax rates (up to 47%).
Can Spanish authorities actually seize Bitcoin?
Technically, no—decentralized assets lack seizure mechanisms. However, centralized holdings (e.g., exchange accounts) could be frozen.
What’s the "traffic light" risk system?
A proposed mandate for exchanges to label crypto assets with color-coded risk ratings (green/yellow/red), akin to food nutrition labels.
