Cryptocurrency taxation in Spain has become increasingly important as digital asset adoption grows. The Spanish tax authorities have introduced new reporting requirements for 2026, making it essential for crypto investors and traders to understand their obligations.
This guide covers everything you need to know about crypto taxation in Spain for 2026, including capital gains tax, reporting requirements, and the new Modelo 721 for foreign crypto holdings.
How Cryptocurrency Is Taxed in Spain
Spain treats cryptocurrency as a digital asset for tax purposes, not as currency. This means that every time you sell, exchange, or use crypto, you may trigger a taxable event.
Cryptocurrency gains are taxed under the savings tax base (base imponible del ahorro), which uses progressive rates separate from your regular income tax:
- Up to €6,000: 19%
- €6,001 to €50,000: 21%
- €50,001 to €200,000: 23%
- €200,001 to €300,000: 27%
- Above €300,000: 28%
These rates apply to capital gains from the sale or exchange of cryptocurrency, as well as gains from staking, airdrops, and other crypto-related income.
Taxable Events for Cryptocurrency
The following activities trigger tax obligations in Spain:
Selling Crypto for Fiat Currency
When you sell cryptocurrency for euros or any other fiat currency, you realize a capital gain or loss. The gain is calculated as the difference between the sale price and the original purchase price (cost basis).
Exchanging One Cryptocurrency for Another
Swapping Bitcoin for Ethereum, or any other crypto-to-crypto exchange, is treated as a disposal of the original asset. You must calculate the gain or loss based on the fair market value at the time of the exchange.
Using Crypto to Purchase Goods or Services
Using cryptocurrency to buy something is treated the same as selling it. You must calculate the gain or loss based on the value of the crypto at the time of the purchase compared to your cost basis.
Staking and DeFi Rewards
Income from staking, yield farming, and other DeFi activities is taxed as capital gains at the time you receive the rewards. The value of the rewards at receipt becomes your cost basis for future disposals.
Airdrops and Forks
Airdrops and tokens received from hard forks are taxed as capital gains at their fair market value when received. This value becomes your cost basis for future disposals.
Calculating Capital Gains and Losses
Spain uses the FIFO (First In, First Out) method for calculating capital gains on cryptocurrency disposals. This means that when you sell or exchange crypto, the cost basis is determined by the price of the oldest coins in your portfolio.
Capital losses can be offset against capital gains in the same tax year. Unused losses can be carried forward for up to four years.
Example Calculation
If you bought 1 BTC for €20,000 in 2021 and sold it for €50,000 in 2025, your capital gain is €30,000. This gain is taxed at the applicable savings rate (21% for the portion between €6,001 and €50,000).
New Reporting Requirements for 2026
Modelo 721: Foreign Crypto Holdings
Starting in 2026, Spanish tax residents must report cryptocurrency holdings held on foreign exchanges using Form 721 (Modelo 721). This form is required if:
- The total value of crypto held on foreign exchanges exceeds €50,000 at any point during the year
- You held crypto on foreign exchanges at the end of the previous tax year with a value exceeding €50,000
The filing deadline for Modelo 721 is March 31 of the year following the reporting year. Penalties for non-compliance are severe, starting at €5,000 per missing data item.
Modelo 720: General Foreign Asset Reporting
Cryptocurrency held on foreign exchanges may also need to be reported on Form 720 (Modelo 720), which covers all foreign assets exceeding €50,000 in any category (bank accounts, securities, real estate, or other assets).
Exchange Reporting Obligations
Under the EU’s DAC8 directive, cryptocurrency exchanges operating in Spain must report user transactions to the tax authorities. This means the Spanish tax agency (AEAT) will receive detailed information about your crypto activity, making accurate reporting essential.
Tax Optimization Strategies
1. Hold Long-Term
While Spain does not offer a specific long-term capital gains discount for cryptocurrency, holding assets for extended periods defers the tax liability and allows your investment to compound without annual tax drag.
2. Harvest Losses
If you have crypto positions that are underwater, selling them to realize losses can offset gains elsewhere in your portfolio. Remember that the wash sale rule does not currently apply to cryptocurrency in Spain, though this could change.
3. Use Tax-Advantaged Accounts
Some pension plans and insurance products in Spain allow investment in cryptocurrency-related products. These may offer tax advantages, though the rules are complex and professional advice is recommended.
4. Relocate to a Favorable Jurisdiction
If you are considering relocating, some European countries offer more favorable crypto tax treatment. Portugal, for example, taxes long-term crypto gains at a flat 28% rate, while Germany exempts gains on crypto held for more than one year.
Filing Your Crypto Tax Return
Cryptocurrency gains and losses are reported on your annual income tax return (Declaracion de la Renta) using Form 100 (Modelo 100). Specifically:
- Capital gains from crypto disposals are reported in the savings tax base section
- Income from staking, mining, and airdrops is also reported as savings income
- Crypto held abroad must be reported on Modelo 721 (if applicable)
The filing deadline for the annual tax return is June 30 of the year following the tax year.
Frequently Asked Questions
Do I need to pay tax if I haven’t sold my crypto?
No. Simply holding cryptocurrency does not trigger a tax obligation in Spain. Tax is only due when you realize a gain through a sale, exchange, or other taxable event.
What records should I keep?
You should maintain detailed records of all crypto transactions, including dates, amounts, prices, and the purpose of each transaction. Most exchanges provide transaction history reports that can be used for tax reporting.
Are NFTs taxed the same as cryptocurrency?
Yes. NFTs are treated as digital assets and subject to the same capital gains tax rules as cryptocurrency. Gains from the sale of NFTs are taxed at the savings rates.
What happens if I don’t report my crypto?
Failure to report cryptocurrency can result in significant penalties, including fines of up to 150% of the unpaid tax, plus interest. With the new DAC8 reporting requirements, tax authorities will receive detailed information from exchanges, making non-compliance increasingly risky.
Key Takeaways
Cryptocurrency taxation in Spain is evolving rapidly. The new reporting requirements for 2026, combined with exchange reporting under DAC8, mean that accurate and complete reporting is more important than ever.
If you hold significant cryptocurrency or engage in frequent trading, working with a tax advisor who understands crypto taxation is essential to ensure compliance and optimize your tax position.
