The Ultimate Guide to Corporate Tax in Spain 2026

Spain is one of Europe’s largest economies and a key destination for international businesses, investors, and entrepreneurs. Understanding how corporate tax works is essential if you are planning to operate in Spain or employ staff locally.

This guide provides a clear overview of Spain’s Corporate Income Tax system, including tax rates, filing obligations, and key considerations for international businesses.

What Is Corporate Income Tax in Spain?

Corporate Income Tax (Impuesto sobre Sociedades) is a direct tax on the profits of companies and legal entities.

• Resident companies are taxed on worldwide income

• Non-resident companies are taxed only on Spanish-source income (typically through a permanent establishment)

• The tax is administered by the Spanish Tax Agency (AEAT)

Corporate tax is filed annually, with advance payments made during the year.

Who Pays Corporate Tax?

Entities subject to corporate tax include:

• Spanish limited companies (S.L., S.A.)

• Permanent establishments of foreign companies

• Associations, foundations, and certain entities

Some organisations may benefit from partial exemptions but still have filing obligations.

Corporate Tax Rates

The general corporate tax rate in Spain is 25%.

Reduced or special rates may apply in certain cases, for example:

• Newly created companies may benefit from a reduced rate (typically 15% for a limited period)

• Financial institutions are subject to higher rates

• Special regimes (such as Canary Islands incentives) may apply under strict conditions

Tax rates and eligibility depend on specific criteria and should always be reviewed case by case.

How Corporate Tax Is Calculated

The taxable base is broadly calculated as:

Income – deductible expenses ± tax adjustments

Common deductible expenses

• Salaries and social security contributions

• Rent and utilities

• Professional services

• Depreciation and amortisation

Non-deductible items

• Fines and penalties

• Certain non-justified expenses

• Some types of donations

Spanish tax rules follow accounting principles, with specific tax adjustments required.

Filing Obligations

Annual return

• Filed using Modelo 200

• Deadline: typically 25 July (for companies with a calendar year)

Advance payments

• Made using Modelo 202

• Usually in April, October, and December

Other filings

• Modelo 232 (related-party transactions)

• Modelo 220 (tax groups, if applicable)

International Considerations

Withholding taxes

Spain applies withholding tax on certain payments such as dividends, interest, and royalties. Rates may be reduced under EU rules or double taxation treaties.

Double taxation treaties

Spain has an extensive treaty network that helps avoid double taxation through:

• Tax credits

• Exemptions

Reporting obligations

Companies or individuals with foreign assets may also be subject to reporting obligations such as Modelo 720.

Anti-Avoidance Rules

Spain applies strict rules in areas such as:

• Transfer pricing (aligned with OECD standards)

• Controlled foreign companies (CFC rules)

• General anti-abuse rules

These rules are actively enforced by the tax authorities.

Tax Groups and Consolidation

Groups of companies may opt for tax consolidation if requirements are met.

This allows:

• Offsetting profits and losses within the group

• Simplified internal transactions

Recent Developments

Spain continues to align with international tax standards, including:

• Implementation of global minimum tax rules for large multinational groups

• Increased focus on compliance and transparency

• Ongoing adjustments to incentives and deductions

Tax rules evolve regularly, so staying updated is important.

Tax Audits and Penalties

The Spanish tax authorities are active in audits, particularly in:

• Cross-border transactions

• Transfer pricing

• Complex structures

Penalties may apply for:

• Late filing

• Underreporting

• Non-compliance

Voluntary correction can reduce penalties.
