Cryptocurrency has moved from the fringes of finance to the mainstream. Spain is no exception. Millions of residents now hold digital assets such as Bitcoin. As a result, the Spanish tax authorities have clarified how crypto is taxed.

For investors in Spain, understanding these tax rules is essential. In many cases, crypto is taxed similarly to other investments such as stocks.

This guide explains how cryptocurrency and Bitcoin are taxed in Spain, including tips for minimizing taxes legally.

What is cryptocurrency and Bitcoin

Cryptocurrency is a digital asset secured by cryptography and recorded on decentralized networks called blockchains. Bitcoin, launched in 2009, is the most well-known example. Other major cryptocurrencies include Ethereum and Solana, along with thousands of smaller tokens used for payments, decentralized finance, and digital collectibles.

According to the Banco de España, direct exposure of Spanish households to crypto-assets remains limited. In 2021, only 4.8% of the Spanish population owned crypto-assets, and for 80% of those households, crypto made up less than 10% of their financial portfolio in 2022.

Still, projections suggest rapid growth. Some forecasts, like Statista’s, indicate crypto adoption could theoretically reach 32% of Spanish adults this year, though this remains a high-end projection rather than a confirmed trend.

Financial advisors continue to recommend treating crypto as a small, speculative portion of an investment portfolio, with BBVA recommending no more than 3%-7% of the portfolio, depending on risk appetite.

How Spanish tax authorities classify cryptocurrency

In Spain, the Agencia Tributaria generally treats cryptocurrency as a capital asset rather than currency. Taxes depend on how the crypto is used:

• Capital gains tax applies when you sell, trade, or spend crypto.

• Income tax applies when crypto is earned through mining, staking, or as salary.

• Wealth tax may apply for large holdings depending on your region.

The bottom line is that profits from cryptocurrency transactions are generally treated as taxable capital gains under Spain’s personal income tax system.

Cryptocurrency capital gains tax in Spain

When you sell cryptocurrency for euros or trade one cryptocurrency for another, you may owe capital gains tax on any profit.

For the 2025/2026 tax year, gains are taxed under Spain’s savings income tax brackets:

Spain uses a progressive tax system for capital gains. This means different portions of your gains are taxed at different rates. For instance, if you realized a 45,000€ net profit from cryptocurrency, you would pay 19% on the first 6,000€, 21% on the next 39,000€, and 23% on any amount above that.

Furthermore, crypto-to-crypto trades are treated as taxable events, meaning exchanging Bitcoin for Ethereum triggers a capital gain or loss calculation. Investors must use the FIFO method (first-in, first-out) to determine the cost basis.

When cryptocurrency is taxed as income

Some cryptocurrency activities are considered income rather than capital gains. These include:

• Mining rewards

• Staking rewards

• Crypto received as salary or freelance payments

• Certain airdrops or promotional rewards

These earnings are taxed under Spain’s general income tax brackets, which can reach up to roughly 47% depending on income and region. If you later sell that crypto, a second tax event occurs on any increase in value since you received it.

Reporting cryptocurrency to Spanish tax authorities

Crypto investors must report transactions on their annual personal income tax return (IRPF). Additional reporting may be required:

• Modelo 721: Residents holding more than 50,000€ in crypto on foreign exchanges must declare these holdings.

• Wealth tax: If total net assets exceed regional thresholds, crypto holdings are included in wealth tax calculations.

Accurate records of purchase prices, transaction dates, and euro valuations are required. Many investors use crypto tax and accounting software that supports Spanish reporting rules to simplify this process.

Crypto Tax Software Options for Spain

Below are tools that help Spanish investors track transactions and prepare tax‑ready reports according to Agencia Tributaria requirements:

These tools can help you automate calculations of gains and losses and produce downloadable reports you can submit to Hacienda yourself or give to your accountant. Some focus exclusively on Spain’s tax forms, while others are global but include Spanish tax compliance features.

Tax rules for foreigners and non-residents

Tax treatment depends on residency status:

• Spanish tax residents: Living in Spain for more than 183 days per year generally means worldwide income and crypto gains are taxable.

• Non-residents: Typically only pay tax on Spanish-source income. Crypto trading outside Spain may not be taxed unless you become a resident.

• Special regimes: Expatriates using Spain’s Beckham Law or other tax regimes may see different treatment, but crypto capital gains are still usually taxable.

Foreign investors should consult local advisors before trading crypto actively in Spain.

Legal strategies to reduce cryptocurrency taxes

While taxes cannot be avoided entirely, investors can use legal strategies:

1. Offset gains with losses: Losses can reduce taxable profits from other crypto sales.

   
   

2. Spread sales across years: Selling over multiple years can help keep gains in lower tax brackets.

   
   

3. Track transaction costs: Trading fees and other costs can be included in the cost basis.

   
   

4. Limit portfolio allocation: Maintaining a small allocation around 5% of total investments limits both financial and tax risk.

   
   

5. Maintain detailed records: Accurate tracking of dates, costs, and euro conversions is essential for compliance.

Compliance is key for cryptocurrency investors in Spain

Cryptocurrency investing is legal and increasingly popular in Spain. Profits from selling or trading crypto are generally taxed as capital gains between 19% and 30%, while income from mining, staking, or crypto payments may be taxed at higher rates.

Staying compliant requires careful record-keeping and awareness of when crypto transactions trigger taxes. Investors who plan ahead can reduce tax liability and avoid penalties.
