Bitcoin & Cryptocurrency Regulation in Spain

Buying, holding, selling and transacting with Bitcoin and other crypto-assets is legal in Spain. There is no ban on private ownership or use, and individuals and businesses may trade through registered or licensed platforms. Crypto is regulated, not prohibited.

Crypto is not, however, legal tender. The euro is Spain's only official currency, so no merchant is obliged to accept Bitcoin, and accepting it is a voluntary commercial decision. Spanish authorities classify crypto-assets as a regulated asset class subject to investor-protection, anti-money-laundering and tax rules, rather than as a parallel form of money. In short, Spain's stance is permissive but cautious, with a strong emphasis on consumer protection and transparency.

Supervision is shared between several authorities, with responsibilities divided by the type of activity:

• CNMV (Comision Nacional del Mercado de Valores), Spain's securities regulator, is the competent authority for authorising and supervising crypto-asset service providers (CASPs) under MiCA, and for conduct, disclosure and advertising rules. See CNMV: MiCA regulation for crypto-assets.
• Banco de Espana (Bank of Spain) previously operated the national anti-money-laundering registry of virtual asset service providers (VASPs). Under MiCA it supervises issuers of electronic money tokens (EMTs) and asset-referenced tokens (ARTs). See the Banco de Espana.
• SEPBLAC, Spain's financial intelligence unit, oversees anti-money-laundering and counter-terrorist-financing obligations, including customer identification and suspicious-activity reporting.
• Agencia Tributaria (AEAT), the tax authority, administers crypto reporting obligations and the collection of any tax due. See the Agencia Tributaria.

At the European level, ESMA and the EBA coordinate the application of MiCA across member states.

The central framework for 2026 is MiCA, the EU's harmonised Regulation on Markets in Crypto-Assets (Regulation (EU) 2023/1114). MiCA entered into force in 2023, and its rules for crypto-asset service providers became applicable across the EU on 30 December 2024. According to the CNMV, Spain's transitional period for firms that were already operating concludes on 1 July 2026, after which only authorised CASPs may serve Spanish users. Some news reports in late 2025 suggested Spain intended to shorten this transition; because such timing details can change, confirm the current deadline directly with the CNMV.

Alongside MiCA, two other strands matter. First, Spain's earlier anti-money-laundering rules under Ley 10/2010 created the Banco de Espana VASP registry, which is being superseded by the MiCA licensing regime. Second, DAC8, the EU directive extending automatic exchange of tax information to crypto-assets, broadens what platforms must collect and report to tax authorities and is being implemented from 2026, reducing the scope for anonymous trading. Spain also has advertising rules requiring that crypto promotions, including those by influencers, carry clear risk warnings.

Before MiCA, crypto exchange and wallet-custody providers had to enrol in the Banco de Espana's anti-money-laundering registry (its full name being the Registro de proveedores de servicios de cambio de moneda virtual por moneda fiduciaria y de custodia de monederos electronicos). Crucially, that registration was an anti-money-laundering formality only: the Bank of Spain has stated that being on the register does not mean it has approved or verified the provider's activity or solvency.

Under MiCA, that national registry is being replaced by a single authorisation regime. The CNMV authorises and supervises CASPs offering services such as exchange, trading and custody, and a Spanish licence can be passported across the EU. The application window for CASP authorisation opened on 30 December 2024. The CNMV granted Spain's first MiCA CASP authorisation to BBVA on 5 March 2025, allowing the bank to offer crypto exchange and custody services to its customers. Existing VASPs registered before 30 December 2024 may continue operating during the transition until they are authorised, refused, or the transition period ends. After the transition closes, providers without MiCA authorisation must exit the Spanish market. When choosing a platform, check its regulatory status with the CNMV.

Crypto is taxable in Spain, and the AEAT treats it as a capital asset rather than as currency. How a transaction is taxed depends on what you did:

• Selling, swapping or spending crypto generally realises a capital gain or loss, taxed as savings income (renta del ahorro) on the difference between acquisition and disposal value. For 2025 the savings-income scale runs in bands, reported at 19 percent up to 6,000 euros, 21 percent from 6,000 to 50,000 euros, 23 percent from 50,000 to 200,000 euros, 27 percent from 200,000 to 300,000 euros, and 30 percent above 300,000 euros. These bands are adjusted from time to time, so confirm the current figures with the AEAT.
• Mining, staking rewards, airdrops, crypto received as salary and certain DeFi yield are generally treated as ordinary (general) income when received, which can be taxed at higher progressive rates.
• Simply holding crypto is not a taxable event, though Spain's wealth tax (Impuesto sobre el Patrimonio) may apply to large net worth, with thresholds and regional reliefs that vary by autonomous community.

Relevant declarations include Modelo 100 (the annual IRPF income-tax return), Modelo 721 (an informational declaration for crypto held on platforms located outside Spain whose value exceeds 50,000 euros as at 31 December, typically due by 31 March), and Modelo 172 and Modelo 173 (information returns filed by Spanish crypto companies). Because rates, thresholds and deadlines change, verify current figures on the Agencia Tributaria website or with a Spanish tax adviser. See also our guide to crypto taxes. This is general information, not tax advice.

Crypto service providers in Spain are obliged entities under anti-money-laundering (AML) and counter-terrorist-financing law. In practice this means you should expect full identity verification (KYC) when opening an account or transacting above low limits, including providing official identification and, in some cases, proof of the source of funds. Platforms must monitor transactions and report suspicious activity to SEPBLAC, Spain's financial intelligence unit.

These obligations originate in Ley 10/2010 (which transposed the EU anti-money-laundering directives) and continue under MiCA and the EU's wider AML package. From 2026, DAC8 further requires crypto platforms to collect and automatically report customer account and transaction data to tax authorities. Users should therefore assume that their crypto activity is identifiable and reportable, and that anonymous trading through regulated platforms is no longer realistic.

Spanish residents can buy crypto through international and domestic exchanges, broker apps and some banks' platforms. The practical rule for 2026 is to use a provider that is MiCA-authorised, either licensed by the CNMV in Spain or passported from another EU member state. A typical compliant route is: choose a licensed platform, complete identity verification (KYC), fund the account in euros (commonly by SEPA bank transfer or card), place your order while reviewing the spread and fees, and, for larger amounts, move holdings to a wallet you control such as a hardware wallet while safeguarding the recovery phrase.

Keep detailed records of the dates, amounts and euro values of every transaction, as you will need them for your annual tax return and any informational declarations. Crypto is not legal tender, so merchant acceptance is voluntary; where it is accepted, spending crypto is generally a taxable disposal. Bitcoin and stablecoins are also sometimes used for cross-border remittances because transfers can settle quickly, but volatility, conversion fees and the need for compliant on- and off-ramps at both ends should be weighed against established remittance services.

Spain hosts one of Europe's larger Bitcoin ATM networks, concentrated in cities such as Madrid and Barcelona. These kiosks let users buy crypto with cash or card, and some support selling back to euros, but they generally charge noticeably higher fees and worse rates than online exchanges. ATM operators are service providers subject to AML obligations and the same MiCA-era licensing expectations as other CASPs, so expect identity checks, particularly above low transaction limits.

Bitcoin mining is legal in Spain. There is no crypto-specific mining ban; the activity is shaped mainly by economics and energy policy. Spain's relatively high electricity costs make large-scale proof-of-work mining challenging compared with cheaper-energy jurisdictions, though there is interest in pairing mining with surplus solar and wind power. Income from mining is generally taxable when earned, and operating commercially brings business-registration, accounting and energy-contract considerations. Anyone planning a commercial operation should seek advice on tax treatment, permitting and electricity arrangements.

The period from 2025 into 2026 has been defined by the rollout of MiCA. The CNMV opened CASP authorisation applications on 30 December 2024 and issued Spain's first MiCA CASP authorisation to BBVA on 5 March 2025. Through 2025 the CNMV published implementation guidelines, including fit-and-proper criteria for board members and shareholders and guidance for financial entities notifying their intention to provide crypto services.

For 2026, two changes stand out. First, the MiCA transition for existing Spanish providers is ending (the CNMV's official page cites 1 July 2026), after which unauthorised providers must leave the market, with some late-2025 reports indicating Spain aimed to accelerate this. Second, DAC8 begins to take effect, expanding automatic tax reporting of crypto activity. A possible future digital euro continues to be explored at the EU level, but that is a central-bank initiative separate from private crypto-assets. For the current position, always rely on the CNMV, the Banco de Espana and the AEAT.

The main risks for Spanish users are familiar: market volatility, scams and fraudulent schemes, platform or custody failure, loss of private keys, and the burden of accurate tax reporting. Spanish authorities have repeatedly warned about high-risk crypto products and misleading promotions, which is why advertising rules require clear risk warnings, including in influencer marketing. Crypto-assets are generally not covered by deposit-guarantee or investor-compensation schemes, so funds held on a failed platform may not be recoverable.

MiCA strengthens consumer protection by standardising authorisation, disclosure (such as crypto-asset white papers) and conduct rules across the EU, but it does not remove market risk: prices can move sharply in either direction, and past performance does not predict future results. To reduce risk, use a CNMV-authorised or EU-passported provider, be sceptical of guaranteed-return offers, use reputable custody, keep records, and only commit capital you can afford to lose. None of this is financial advice; consider consulting a regulated adviser before investing.

Because crypto rules and tax thresholds in Spain change frequently, always confirm the current position with the official authorities rather than relying on third-party summaries. The primary sources are:

• CNMV: MiCA, new regulation for crypto-assets, the regulator's hub for CASP authorisation, supervision and the transition timeline.
• Banco de Espana, for the former VASP registry and for oversight of electronic money tokens and asset-referenced tokens.
• Agencia Tributaria (AEAT), for tax obligations and forms such as Modelo 100, Modelo 721, Modelo 172 and Modelo 173.
