Navigating the tax implications of cryptocurrencies in Spain can be complex, especially as regulations continue to evolve. This comprehensive guide breaks down everything you need to know—from how crypto gains are taxed and how to report them on your tax return, to new reporting requirements and potential penalties for non-compliance. While this article provides detailed insights, always consult a qualified tax advisor familiar with digital assets before filing.
What Are Cryptocurrencies?
In late 2008, an individual or group under the pseudonym Satoshi Nakamoto published the whitepaper "Bitcoin: A Peer-to-Peer Electronic Cash System." This groundbreaking document proposed a decentralized alternative to traditional financial systems by eliminating the need for intermediaries like banks in digital transactions.
By early 2009, the Bitcoin network was launched, marking the birth of cryptocurrencies—digital or virtual currencies secured by cryptography. Unlike fiat money controlled by governments, cryptocurrencies operate on decentralized networks based on blockchain technology.
These digital assets are not physical, but they function as mediums of exchange and can be traded for traditional currencies like the euro. In fact, Spain has recognized cryptocurrencies as a legal means of payment since 2015, although they are not considered official currency.
Today, thousands of cryptocurrencies exist beyond Bitcoin, including Ethereum, Litecoin, Monero, and Neo—each with unique protocols and use cases such as smart contracts, privacy-focused transactions, or decentralized finance (DeFi) applications.

How Are Cryptocurrencies Taxed in Spain?
In Spain, any capital gains from cryptocurrency transactions must be declared in your annual income tax return (Declaración de la Renta). Losses are not mandatory to report but are highly recommended so they can be offset against future gains.
The Spanish Tax Agency (Agencia Tributaria) treats cryptocurrency holdings held abroad with particular scrutiny. If your total value in foreign-based crypto assets exceeds €50,000 at any point during the year, you are required to file Form 721—the updated version of the former Form 720.
Failure to comply can lead to severe consequences, including fines up to €200,000, even if no tax is owed. The goal is transparency: authorities want a clear picture of Spanish residents’ offshore digital asset holdings.
Key tax principles include:
- Gains are taxed under Personal Income Tax (IRPF) as capital gains.
- There is no Wealth Tax on crypto in Spain—yet—but local regions may reassess this.
- Transactions are evaluated using the FIFO method (First In, First Out) when calculating profit or loss across multiple trades.
How to Report Cryptocurrencies on Your Tax Return
You must report all crypto-related capital gains in your Spanish income tax declaration. While reporting losses is optional, doing so allows you to carry forward those losses to offset future profits, reducing your taxable base.
To declare correctly, first identify the nature of your income:
Types of Crypto Income and Reporting Categories
- Capital Gains from Disposal: Applies when you sell, swap, or spend cryptocurrencies. This is the most common taxable event.
- Non-Disposal Gains: Includes rewards like airdrops or referral bonuses—not tied to buying/selling.
- Yield-Bearing Activities: Such as staking, where you lock up coins to support network operations and earn returns.
- Economic Activity Income: Generated through mining or professional trading services offered to others.
For standard disposals, use Box 1626 on your tax form. Enter the acquisition date, cost basis, disposal date, and sale value. The tax software will calculate your gain or loss automatically.
When trading frequently, remember that Hacienda uses the FIFO accounting method—your earliest-purchased coins are assumed sold first.
New Cryptocurrency Reporting Requirements in Spain
Regulatory oversight is tightening. Here’s what’s changed:
Form 721 – Foreign Crypto Asset Disclosure
This form replaces the old Form 720 and targets taxpayers holding crypto assets worth over €50,000 outside Spain. Required details include:
- Personal identification
- Public wallet address
- Amount held at the beginning and end of the fiscal year
Late or inaccurate filings trigger penalties starting at €10,000, with additional fines per missing data point.
Forms 172 and 173 – For Crypto Businesses
Spanish-resident companies involved in crypto must submit these new forms annually. Covered entities include:
- Cryptocurrency exchanges
- Wallet providers
- Firms conducting Initial Coin Offerings (ICOs)
They must report all client transactions globally—including purchases, sales, swaps, transfers, and payments—along with taxpayer IDs, volumes, and values.
These measures reflect Spain’s alignment with EU-wide anti-money laundering (AML) standards and increased financial transparency goals.

VAT and Income Tax on Buying and Selling Cryptocurrency
Value Added Tax (IVA)
Under EU guidelines adopted by Spain, cryptocurrency transactions are exempt from VAT. This includes:
- Buying or selling crypto
- Mining activities
- Exchanging one cryptocurrency for another
Since mining isn’t considered a service provided to a specific customer, there's no taxable event—and thus no VAT applies. However, this also means miners cannot deduct VAT paid on related expenses like electricity or hardware.
Personal Income Tax (IRPF)
If you trade crypto as a business—for example, as a self-employed trader—you may need to register under the appropriate economic activity code (epígrafe) in the IAE (Economic Activities Tax).
Most crypto traders fall under epígrafe 831.9 ("Other Financial Services n.c.o.p.") due to lack of specific classification.
Profits from regular trading are treated as income from economic activities, not capital gains. This affects deductions, tax rates, and record-keeping requirements.
Bitcoin ATMs in Spain: How They Work
Bitcoin ATMs are becoming increasingly common across major Spanish cities like Madrid and Barcelona. While they resemble traditional ATMs, their function differs significantly:
Instead of using a bank card, users deposit cash and scan a QR code linked to their digital wallet to receive crypto instantly.
Here’s how it works:
- Select the cryptocurrency (usually BTC or ETH).
- Deposit euros in cash.
- Confirm your wallet address via QR code.
- Receive crypto directly to your wallet within minutes.
These machines connect to external exchanges to determine pricing and often charge higher fees than online platforms—typically between 5% and 10%.
All transactions require identity verification under AML rules. Users must provide ID (DNI or passport), phone number, and email.
While convenient for beginners, frequent traders should consider regulated exchanges for better rates and audit trails needed for tax reporting.
Penalties for Not Declaring Cryptocurrencies
The Spanish Tax Agency has prioritized cryptocurrency monitoring in its Annual Tax Control Plan. Non-compliance carries serious risks:
Fines Related to Form 721 (Foreign Assets)
- €5,000 per undeclared account or inaccurate data
- Minimum penalty: €10,000
- Late submission: €100 per data item (minimum €1,500)
- Paper filings when electronic submission is required: also penalized
Fines for Income Tax (IRPF) Evasion
- Minimum surcharge of 26% on unpaid taxes
- Example: If you failed to pay €950 on €5,000 in gains (19%), the fine starts at €247
- Can rise significantly depending on intent and duration
Voluntary disclosure through a complementary tax return reduces penalties:
- 5% surcharge if filed within three months
- Up to 20% after one year
