How crypto founders, DeFi teams, token issuers and fintech operators structure their Spanish business — SL formation, MiCA compliance, Banco de España registration, token taxation, Modelo 721 for crypto holdings, and the regulatory reality of running a crypto-exposed business from Spain.
Crypto and fintech in Spain operate under a rapidly-evolving regulatory regime. MiCA (Markets in Crypto-Assets Regulation) applies EU-wide from 2024-2025 with full phase-in through 2026, setting the rules for CASPs (crypto-asset service providers), stablecoin issuers and token offerings. Before MiCA, Spain was one of the stricter EU regulators on crypto — all CASPs must register with Banco de España and AML-compliance is rigorously enforced.
For crypto founders — whether running a CASP, a DeFi protocol, a token-issuing project or simply holding crypto personally — Spain offers structured opportunity but requires careful navigation. Tax treatment of crypto is defined: capital asset for individuals, trading asset for active traders, ordinary income for staking and mining. Modelo 721 (from 2024) declares foreign-held crypto annually.
This page covers the regulatory framework, the tax treatment of crypto income types, the SL structure typically used, and the compliance pattern required to run a crypto-exposed business in Spain without regulatory or tax surprises.
Tax structuring, entity formation and sector-specific compliance for crypto founders, DeFi teams, token issuers, fintech startups and payment service providers. Scoped at the outset with a written fee proposal.
Four commercial realities shape every Crypto & Fintech engagement in Spain.
Any business providing crypto services in Spain — exchange, custody, wallet services, token issuance to residents — must register with Banco de España under the AML regime. Registration requires internal AML procedures, KYC processes, suspicious-transaction reporting and regulated-officer appointments.
MiCA phase-in (2024-2026) adds CASP licensing, operational resilience, governance and consumer protection requirements. Operating as a CASP without MiCA licence post-transition is criminal.
Personal crypto holdings: capital assets. Gains on disposal taxed as capital gains under the savings base of IRPF (19-28%).
Staking rewards: ordinary income at receipt (FMV in EUR at moment of receipt); plus subsequent CGT on disposal.
Mining: business income (autónomo activity). Requires activity registration and all the regular compliance.
Airdrops: ordinary income at receipt (FMV).
DeFi activity: each transaction is a potential taxable event. Yield farming, LP positions and token swaps all trigger events.
From 2024, Spanish tax residents must declare foreign-held crypto on Modelo 721 annually, threshold €50,000 per category. Similar to Modelo 720 for foreign financial assets but specifically for crypto held via foreign platforms (Binance, Coinbase outside Spain, DeFi wallets).
Penalties for non-filing are material. Enforcement is expected to accelerate as Hacienda's crypto tracing improves.
Token issuance by Spanish SL: depending on token classification (utility, security, payment), different regulatory regimes apply. Securities tokens fall under CNMV; payment tokens under Banco de España; utility tokens may fall outside traditional securities regulation.
Tax: token issuance proceeds may be treated as service income, deferred revenue, or capital depending on structure. Careful structuring matters for both corporate tax and IVA (tokens granting access to future services may be IVA-taxable at issuance).

Illustrative client profiles across the sector.
The situation. UK fund manager relocating, $80M AUM crypto hedge fund, Cayman feeder structure.
How we'd handle it. Spanish SL as Spanish sub-advisor to Cayman fund manager. Beckham Law election. Transfer pricing at cost-plus management fee. Modelo 721 for any Spanish-sourced crypto in personal holding. Regulatory analysis confirmed sub-advisor role does not trigger MiCA CASP requirements.
The situation. Three-founder DeFi protocol, $50M TVL, token launched 2023, founders now Spanish-resident.
How we'd handle it. Spanish SL for operational entity (development work, marketing). Token issuance entity kept offshore (Swiss foundation) with arm's-length service agreement to Spanish SL. Founder tokens analyzed for vesting income vs capital treatment. Modelo 721 filed. Beckham elected.
The situation. Spanish SL providing crypto-to-fiat conversion for European merchants, €3M revenue, seeking MiCA licensing.
How we'd handle it. Banco de España CASP registration renewed. MiCA licence application underway. AML policies updated. Spanish SL; no offshore structure (regulated activity needs regulated entity).
The situation. American crypto investor with $2M portfolio, active trading and some DeFi yields, relocated.
How we'd handle it. Personal tax structure — no SL needed for passive investment. CGT on disposals under savings base. Modelo 721 for foreign-held crypto. US Form 8938 and FBAR coordination. Considering SL if active-trading test becomes triggered.
Recurring errors specific to this sector — and how we prevent each.
Providing crypto services to Spanish customers without Banco de España registration is a regulatory breach. Fines and criminal exposure.
Foreign-held crypto above €50k threshold requires declaration. Enforcement is ramping.
Treating a security token as utility misses CNMV registration, triggering regulatory action.
Every LP add/remove and swap is potentially a taxable event. Under-reporting DeFi activity is high-risk as blockchain traceability improves.
Offshore foundations run from Spain by Spanish-resident directors can be claimed as Spanish tax-resident. Keep offshore genuinely offshore.
Active crypto mining is a Spanish business activity — requires autónomo or SL registration and IRPF/IS/IVA treatment. Ignoring this creates retroactive exposure.
Most crypto & fintech engagements start with a structure call where we understand the specifics — revenue, client geography, operational setup, existing entities, residency status. We don't start recommending entity types before we understand the numbers.
After the call we send a written recommendation with sector-specific tax modelling. You see actual numbers — SL vs autónomo, Beckham vs progressive, R&D credit where applicable, VAT treatment per client geography.
If you engage, we issue a written scope and fixed fee. Scope is specific to the sector — OSS registration for e-commerce, CASP registration for crypto, vivienda de uso turístico for property, image-rights licence for creators. Fee is fixed, in writing, before work begins.
We execute. You get a named point of contact. Weekly status during active phases. English-language throughout. Coordinated with your home-country advisor where applicable.
We hand over to an ongoing compliance provider — typically a gestor or small accounting firm — with a written 12-month compliance calendar. You don't lose visibility after setup, and we stay available for follow-up questions indefinitely.
Spain has thousands of gestores who can register an SL. What's scarce is sector-specific commercial capability — lawyers who understand how crypto & fintech actually operate, what goes wrong in your sector, and how to structure setup to prevent it.
