Spain, as the 14th largest economy in the world, offers access to a dynamic EU market and a range of tax optimization opportunities. The country’s tax system is administered by the Spanish Tax Agency (Agencia Tributaria), which oversees the implementation, management, inspection, and collection of taxes. While no specific crypto tax regulations have been issued yet, general tax principles apply to cryptocurrency-related activities.
Corporate tax periods align with accounting periods and must not exceed 12 months. It's important to note that Spain’s autonomous communities have the authority to modify national tax rules—such as exemptions, rates, and deductions—meaning your final tax liability may vary depending on where your business operates. According to the 2020 Regional Competitiveness Report, Madrid, Navarre, the Basque Country, and Catalonia rank among Spain’s most entrepreneurial and competitive regions.

Tax Incentives for Innovation and Growth
Spain offers attractive incentives for companies engaged in research and development (R&D) and technological innovation:
- 25% tax credit on qualifying R&D expenses
- Additional 12% credit for technology-driven initiatives
- Extra 17% credit when employees with R&D qualifications are involved
These credits can significantly reduce effective tax rates for startups and tech-focused firms, including those in the blockchain and digital asset space.
Spain also benefits from over 90 double taxation treaties with countries worldwide. These agreements help prevent international tax duplication and can lower withholding taxes on dividends, capital gains, and royalties. However, only companies recognized as Spanish tax residents qualify for treaty benefits.
A company is considered a Spanish tax resident if:
- It was incorporated under Spanish law
- Its registered office is in Spain
- Its effective management and control are based in Spain
This residency status determines whether a company pays tax on global income (residents) or only Spanish-sourced income (non-residents).
Corporate Income Tax for Crypto Businesses
The standard corporate income tax rate in Spain is 25%, applicable to most businesses—including crypto exchanges, wallet providers, NFT platforms, and blockchain developers.
However, several preferential rates support early-stage companies:
Reduced Rates for Startups
Newly established companies may benefit from:
- 10% reduced rate during the first profitable tax period and the following one
(Excludes companies spun off from existing entities or part of corporate groups) - 15% flat rate for qualifying startup companies over their first four profitable years
To qualify as a startup under Spanish law, a company must meet all of the following conditions:
- Founded within the last 5 years (or 7 years for strategic sectors or tech-developed-in-Spain)
- Registered office or permanent establishment in Spain
- Operate an innovative, scalable business model
- Not formed through merger, split, or transformation
- No dividend distributions made
- Not listed on a regulated stock exchange
- At least 60% of employees employed under Spanish labor contracts
Tax filings follow a self-assessment model. Annual corporate income tax returns must be filed within 25 calendar days of the sixth month after the end of the fiscal year. For example, if your fiscal year ends on December 31, the deadline would be July 25 of the following year.
VAT on Cryptocurrency and Digital Assets
Spain applies a standard VAT rate of 21% to most goods and services provided domestically or imported into the country. However, crypto-related services are treated differently under EU VAT directives.
Exempt Crypto Activities
Under EU law:
- Crypto mining, free transfers, and token swaps are VAT-exempt
- Buying/selling crypto is treated like currency exchange—no VAT applies
- Storing or transferring crypto assets remains outside VAT scope
When VAT Applies
- Paid wallet or custody services: Subject to 21% VAT
- Payment in crypto: Transactions using crypto for goods/services are taxed like any other sale
- NFT sales: Treated as electronic services—subject to 21% VAT
NFT sellers must determine the buyer’s location to apply correct VAT rules. If annual sales to EU consumers exceed €10,000 and involve cross-border transactions, VAT must be paid in the customer’s home country under the EU’s OSS (One Stop Shop) scheme.

Capital Gains Tax on Crypto Transactions
In Spain, profits from selling, trading, or disposing of cryptocurrencies are classified as capital gains (ganancias patrimoniales) and taxed under the savings income bracket.
The progressive capital gains tax rates for 2025 are:
- Up to €6,000: 19%
- €6,000 – €50,000: 21%
- €50,000 – €200,000: 23%
- Over €200,000: 26%
These rates apply to net gains calculated per taxpayer (not per transaction), so losses can offset gains in the same year.
Frequent traders may be reclassified as conducting an economic activity—especially if trading is systematic and profit-driven. In such cases, income falls under economic activities income (rendimientos de actividades económicas) and is taxed at personal income rates up to 47%, depending on region and total earnings.
Wealth Tax on Crypto Holdings
Spain imposes an annual wealth tax ranging from 0.2% to 3.5%, based on net asset value as of December 31 each year.
Residents enjoy a €700,000 exemption threshold, though this varies slightly by autonomous community. Non-residents are taxed only on Spanish-situated assets.
Crypto holdings—whether held directly or through corporate shares—are included in net wealth calculations.
Exemption for Entrepreneurial Shares
Individuals may qualify for full exemption on shares in unlisted or listed companies if they:
- Own at least 5% of voting rights (including family holdings)
- Serve as active managers earning ≥50% of net income from the company
- Ensure asset management isn’t the company’s primary activity
This can be highly beneficial for founders and executives of Spanish crypto firms.
Social Security Contributions
Employers operating in Spain must register employees with Social Security. Contributions are shared between employer and employee:
- Employer pays: 29.9% of gross salary
- Employee pays: 6.34% of gross salary
- Total: 36.24%
There is a monthly cap on contributions—currently set at €4,139.40 per employee.
Contributions provide access to:
- Healthcare
- Unemployment benefits
- Maternity/paternity leave
- Disability allowances
- Retirement pensions
How to Report Crypto Income in Spain (2025)
All crypto-related income must be reported accurately to avoid penalties. Here's how:
