Spain corporate tax has positioned the country as one of Europe’s most attractive destinations for business growth and international investment.

Recent corporate tax reforms have brought significant changes to Spain corporate tax rules, opening new opportunities for different types of businesses.
From updated SME taxation rules and enhanced startup incentives under Spain’s Startup Law 28/2022 to advantageous ETVE holding structures for international groups, the landscape is shifting in favour of innovation, growth, and cross-border investment.
Whether you are a small business exploring how to set up a business in Spain, a new venture launching under startup tax incentives, or an established multinational planning cross-border expansion into Spain, understanding Spain corporate tax is essential for optimising your tax position.
Standard rate and basic framework of Spain corporate tax
The base rate of Spain corporate tax (Impuesto sobre Sociedades) is 25% for most resident companies.
According to AEAT official guidance, this standard rate applies to corporate income and aligns Spain with most EU member states.
However, the actual effective rate varies significantly depending on company size, type, sector, and structure, with numerous reduced rates and special regimes available.
Resident vs non-resident companies under Spain corporate tax
How Spain corporate tax applies depends critically on your company’s tax residency status:
| Company Type | Tax Base | Key Characteristics |
|---|---|---|
| Resident companies | Worldwide income | Taxed on all global profits; full access to Spanish tax incentives and treaty benefits |
| Non-resident (with PE) | Spanish-source income through permanent establishment | Branch operations; same rate as residents but limited deductions |
| Non-resident (without PE) | Spanish-source income only | Subject to Non-Resident Income Tax (IRNR); withholding tax regime |
Understanding this distinction is crucial when planning your legal structure for operating in Spain.
2026 reduced rates: SMEs, micro-enterprises, and startups
One of the most significant recent developments in Spain corporate tax is the progressive reduction of rates for smaller companies and innovative startups.
SME corporate tax rates (turnover under €10 million)
According to official Spanish administration guidance, SMEs with annual turnover below €10 million benefit from reduced Spain corporate tax rates that decrease progressively through 2029.
| Tax Year | SME Rate | Savings vs Standard (25%) |
|---|---|---|
| 2025 | 24% | 1 percentage point |
| 2026 | 23% | 2 percentage points |
| 2027 | 22% | 3 percentage points |
| 2028 | 21% | 4 percentage points |
| 2029+ | 20% | 5 percentage points |

Micro-enterprise rates (turnover under €1 million)
Micro-enterprises benefit from even more favourable treatment under Spain corporate tax through a tiered bracket system.
According to PwC tax summaries, these companies enjoy lower rates on the first €50,000 of taxable income, with slightly higher rates on the excess.
| Tax Year | Rate on First €50,000 | Rate on Excess | Effective Rate (€100k profit) |
|---|---|---|---|
| 2025 | 21% | 22% | 21.5% |
| 2026 | 19% | 21% | 20.0% |
| 2027 | 17% | 20% | 18.5% |
| 2028+ | 17% | 20% | 18.5% |
This tiered structure under Spain corporate tax creates meaningful savings for smaller operating companies planning early-stage growth and managing cash flow efficiency.
Startup corporate tax rate: 15% for qualifying new companies
Qualifying startups and newly incorporated companies benefit from a special 15% Spain corporate tax rate for their first two profitable tax periods.
Startup tax benefits under Spain’s Startup Law 28/2022
- 15% corporate tax rate for first two profitable years (vs 25% standard)
- Applies to newly created companies and certified innovative startups
- Must be registered in Commercial or Cooperative Registry within last 5 years (7 years for biotech/energy)
- Certification from ENISA (National Innovation Company) required for full benefits
- Cannot be formed primarily by shareholders who previously operated same activity
- Enhanced investor deductions: 50% deduction on investments up to €100,000 annually
- Stock option tax deferral benefits for employees
This favourable Spain corporate tax treatment for startups makes Spain increasingly competitive with other European innovation hubs.
Enhanced capitalisation reserve: reducing Spain corporate tax through equity growth
One of the most valuable planning tools under Spain corporate tax is the enhanced capitalisation reserve, which allows companies to reduce their taxable base when they increase equity.
According to PwC guidance on tax credits and incentives, the reduction percentages are tied to workforce growth, creating additional benefits for companies that create jobs.
| Workforce Growth | Tax Base Reduction | Requirements |
|---|---|---|
| Standard (no requirement) | 20% | Equity increase maintained |
| +2% to +5% increase | 23% | Workforce level maintained for specified period |
| +5% to +10% increase | 26.5% | Additional documentation required |
| Over +10% increase | 30% | Higher reduction for significant job creation |
This mechanism within Spain corporate tax rewards companies that strengthen their equity base while simultaneously creating employment.
Branch vs subsidiary: choosing the right structure for Spain corporate tax
Foreign companies expanding into Spain must decide between establishing a branch (permanent establishment) or creating a Spanish subsidiary.
This structural decision significantly impacts how Spain corporate tax applies and which incentives are available.
| Structure | Tax Treatment | Advantages | Limitations |
|---|---|---|---|
| Branch (PE) | Same corporate tax rate; Spanish-source income only | Simpler setup; losses may offset parent company profits | Restricted deductions; limited treaty benefits; less access to incentives |
| Subsidiary (SL) | Full resident company treatment on worldwide income | Complete access to SME rates, startup incentives, R&D credits, treaty network | Higher administrative burden; separate legal entity requirements |
For most foreign companies planning substantial operations, a subsidiary structure provides far more flexibility for optimising Spain corporate tax through access to reduced rates and special regimes.
Understanding Spanish commercial law requirements is essential when establishing either structure.
ETVE holding regime: optimising Spain corporate tax for international groups
The ETVE (Entidad de Tenencia de Valores Extranjeros) regime represents one of the most powerful tools within Spain corporate tax for foreign companies managing international shareholdings.
This participation exemption regime offers substantial tax benefits for qualifying holding structures and is particularly valuable for cross-border M&A and international investment.
ETVE regime key benefits
- Participation exemption: Up to 95-100% exemption on dividends and capital gains from qualifying foreign subsidiaries
- Minimum shareholding: Generally 5% direct ownership held for at least 1 year
- Treaty network access: Benefit from Spain’s extensive double taxation treaty coverage (90+ countries)
- Reduced withholding: Potentially reduced or eliminated withholding taxes under EU directives and bilateral treaties
- Low administrative burden: Streamlined compliance with proper accounting support
- EU directive alignment: Compatible with Parent-Subsidiary Directive for intra-EU structures
The ETVE regime makes Spain corporate tax particularly attractive for multinational groups structuring their European or global operations.
For detailed analysis, see our comprehensive guide to the ETVE tax regime in Spain.
EU Pillar Two minimum tax and Spain corporate tax
Large multinational groups must now consider EU Pillar Two rules as part of Spain corporate tax planning.
Spain has implemented the EU Council Directive 2022/2523 establishing a global minimum effective tax rate of 15% for qualifying multinational groups.
This affects groups with consolidated annual revenue exceeding €750 million and ensures they pay at least 15% effective tax in each jurisdiction where they operate, through a Top-Up Tax mechanism where necessary.
While this primarily impacts very large corporations rather than SMEs or startups, it demonstrates Spain’s alignment with international tax standards and OECD frameworks.
R&D and innovation incentives under Spain corporate tax
Spain offers substantial tax credits and deductions for research, development, and technological innovation that can significantly reduce effective Spain corporate tax rates.
| Incentive Type | Credit/Deduction Rate | Key Features |
|---|---|---|
| R&D expenses | 25% base rate; 42% on excess over average of prior 2 years | Applies to qualifying research and development activities |
| Technological innovation | 12% on qualifying innovation costs | Separate from R&D; covers technological advancement activities |
| Patent Box regime | 10% effective rate on qualifying IP income | Applies to income from patents and other qualifying intellectual property |
These R&D incentives can be combined with reduced SME or startup rates, creating highly competitive effective Spain corporate tax rates for innovative companies.
Regional tax advantages: Comunidad Valenciana and Canary Islands
Regional measures can significantly enhance the benefits of Spain corporate tax planning, particularly in the Valencian Community and Canary Islands.
Comunidad Valenciana wealth tax threshold increase
The Valencian Community increased its wealth tax exemption threshold from €500,000 to €1,000,000, providing substantial relief for entrepreneurs, business owners, and investors operating in the region.
This regional advantage, combined with Valencia’s strategic Mediterranean location, world-class port infrastructure serving European and North African markets, and strong digital and tech ecosystem, makes the region particularly attractive for business expansion.
Canary Islands Special Zone (ZEC)
The Canary Islands ZEC regime offers an extraordinarily low 4% Spain corporate tax rate for qualifying companies that establish operations in the islands and meet investment and employment requirements.
New companies may register for ZEC status until 31 December 2026, with the regime applicable until 31 December 2032, making this one of the most attractive corporate tax environments in the EU.
Filing obligations and compliance calendar
Companies subject to Spain corporate tax must comply with strict filing deadlines:
| Filing | Purpose | Deadline |
|---|---|---|
| Modelo 200 | Annual corporate tax return | Within 25 days of 6th month after fiscal year-end (July for calendar-year companies) |
| Modelo 202 | Quarterly advance corporate tax payments | April, October, December (generally 18% of prior year liability) |
| Modelo 303 | Quarterly VAT return | Within 20 days after each quarter |
| Modelo 347 | Annual declaration of operations over €3,005.06 | February (for previous year) |
Proper compliance with Spain corporate tax filing requirements is essential to avoid penalties and maintain good standing with Spanish tax authorities.
Our tax law and accounting services ensure timely and accurate compliance with all obligations.
