Crypto in Spain 2026: AEAT Tax Rules and MiCA Implementation

Spain taxes crypto at 19–28% as savings income. The AEAT has been actively requiring crypto disclosures since 2021. This guide covers Spanish crypto tax rules and the regulatory landscape.

Spain has been one of the more proactive EU countries in crypto taxation, introducing mandatory disclosure requirements and Form 720 (overseas asset declarations) requirements for crypto. Spanish crypto users face clear but relatively high tax obligations.

Spanish Crypto Tax (AEAT Rules)

MiCA Implementation in Spain

Spain's CNMV (securities regulator) and Banco de España (central bank) jointly supervise crypto service providers. Spain was one of the first EU countries to begin transitioning VASP registrations to the full MiCA authorization framework. Binance, Coinbase, and several local exchanges completed MiCA transition through Spanish regulatory channels.

Self-Custodial DeFi from Spain

Spanish residents can freely access self-custodial DeFi platforms. Self-custodial activity is not regulated as financial services under Spanish law or MiCA. Tax obligations on all DeFi activity remain — Spanish users are advised to use tax software that handles Ethereum, Solana, and DeFi protocols for complete AEAT compliance.
