How to buy bitcoin legally in Spain
This is general information, not legal, tax, or financial advice. Crypto rules change often. Verify the current position with a qualified local professional and the official regulator, the CNMV and the Agencia Tributaria, before acting.
Buying and holding bitcoin is legal in Spain. As of April 2026 you buy it through a crypto asset service provider authorised under the European Union framework MiCA and supervised by the CNMV, after completing identity checks. There is no tax on buying, but selling or swapping bitcoin is a taxable disposal that the Agencia Tributaria taxes in the savings base.
Is it legal to buy bitcoin in Spain?
Yes. As of April 2026 buying, holding, and selling bitcoin is legal for residents of Spain. A private individual does not need a licence to own bitcoin. The obligation to be authorised falls on the platform that provides the service, not on you as the customer. Spain applies the European Union framework MiCA, the Markets in Crypto Assets regulation, and the lead authority that authorises and supervises crypto asset service providers in Spain is the CNMV, the Comision Nacional del Mercado de Valores.
To serve Spanish residents from 1 July 2026, a platform needs a granted MiCA authorisation, either obtained in Spain through the CNMV or passported from another member state. The national window for firms that operated under the earlier Banco de Espana register ran to 30 June 2026. Because authorisations were still being processed through the first half of 2026, confirm a platform's current status in the official register before you sign up.
How to buy bitcoin compliantly
The straightforward way to buy bitcoin legally in Spain is through an authorised exchange. As of April 2026 the typical steps are: choose a platform that is authorised under MiCA to serve Spain, complete the identity verification required under anti money laundering rules, fund the account with euro by SEPA bank transfer or card, and place an order. You can leave the bitcoin in the platform's custody or move it to a wallet you control. Self custody removes platform risk but places the responsibility for keys and backups on you.
Buying bitcoin with cash directly from another person is also lawful, but person to person deals carry counterparty and fraud risk and still create the same tax record keeping duties. Whichever route you take, keep a record of the euro value and date of every purchase, because Spanish tax is calculated from your full transaction history.
Tax when you buy and sell
Buying bitcoin and simply holding it does not trigger tax in Spain. Tax arises when you dispose of it, which means selling it for euro or swapping it for another crypto asset. As of April 2026 that gain falls in the savings tax base, the base del ahorro, taxed on a sliding scale that runs from 19 percent on the first 6,000 euros up to 30 percent above 300,000 euros. The Agencia Tributaria, the AEAT, applies the first in, first out method, known as FIFO, and treats a crypto to crypto swap as a taxable disposal even though no euro changes hands.
Crypto held on platforms or in custody outside Spain above a total value of 50,000 euros must be declared on Modelo 721, an informational return that is separate from paying tax on gains. This is general tax information, not tax advice. The Agencia Tributaria sets the rates, thresholds, and deadlines, which can change each year, and your position depends on your circumstances and region. Verify before you file.
