Are crypto wallets legal in Spain?
Holding crypto in a wallet you control, known as self custody, is legal in Spain as of March 2026. There is no law that bans owning a software or hardware wallet, and an individual does not need a licence to hold their own crypto. A business that holds or administers crypto for customers provides a custody service that needs authorisation under the European Union MiCA framework, supervised by the Comision Nacional del Mercado de Valores, the CNMV, and the crypto in any wallet you own is taxed by the Agencia Tributaria.
The rules in detail
A crypto wallet stores the keys that let you move your crypto. With a self custody wallet, whether a phone app, a browser extension, or a hardware device, you hold the keys yourself. With a custodial wallet, a company holds the keys for you. As of March 2026 owning and using a self custody wallet is legal in Spain, and individuals do not need a licence to hold their own crypto.
The regulated activity is custody for others. Under the Markets in Crypto Assets Regulation, MiCA, the custody and administration of crypto assets on behalf of clients is a crypto asset service. A firm that offers a custodial wallet or holds customer crypto generally needs authorisation as a crypto asset service provider. In Spain the CNMV is the lead authority that authorises and supervises these providers as of March 2026, while the Banco de Espana covers payment and electronic money aspects. Holding your own keys in a self custody wallet does not make you a regulated provider.
How wallet holdings are taxed
The Agencia Tributaria taxes crypto by reference to what you do with it, not by where it is stored, so the wallet itself is not separately taxed. As of March 2026, for a private holder, selling or swapping crypto held in a self custody wallet is a disposal taxed as savings income on a sliding scale that runs from 19 percent to 30 percent, the same treatment as crypto held on an exchange. Moving crypto between your own wallets is not in itself a taxable disposal, but you still need records of value. Crypto held on platforms outside Spain worth more than 50,000 euros must be reported on Modelo 721, a reporting obligation separate from paying tax on gains. Keep euro records of acquisitions, disposals, and balances. Verify before filing.
Choosing and using a wallet compliantly
Most people buy crypto on a regulated exchange and then decide whether to leave it in the exchange custodial wallet or move it to a self custody wallet they control. With self custody you take on full responsibility for your keys and recovery phrase, and there is usually no provider to restore access if you lose them. To buy the crypto you intend to hold, use a platform that is authorised under MiCA to serve Spain. We do not endorse any specific wallet product.
