Spain's CFC Rules (Transparencia Fiscal Internacional): When Your Offshore Company Becomes Taxable in Spain

Introduction: Spain's CFC Framework

Spain's Controlled Foreign Company (CFC) rules — known in Spanish as Transparencia Fiscal Internacional (TFI) — are one of the most potent anti-avoidance tools in the Spanish tax arsenal. These rules allow Spanish AEAT to attribute the passive income of a foreign company directly to its Spanish-resident shareholders or corporate controllers, making them taxable in Spain on income that has not been distributed and may be sitting in a low-tax jurisdiction.

The rules were originally enacted in the 1990s and have been progressively strengthened under the influence of the EU Anti-Tax Avoidance Directive (ATAD) and the OECD BEPS project. They represent a significant risk for Spanish tax residents who hold interests in offshore companies, particularly holding vehicles, investment companies, and financial intermediaries located in low-tax jurisdictions.

The Two CFC Regimes: Individuals (Article 91 LIRPF) and Companies (Article 100 LIS)

Spain operates two parallel CFC regimes:

• Article 91 LIRPF: Applies where the Spanish taxpayer is an individual resident for IRPF purposes. The attributed income is included in the individual's general IRPF base at progressive rates up to 47% (or higher in some autonomous communities)
• Article 100 LIS (Ley del Impuesto sobre Sociedades): Applies where the Spanish taxpayer is a company. The attributed income is included in the company's taxable base at the standard corporate rate of 25%

The substantive conditions for attribution are broadly similar in both regimes, though there are some technical differences. This guide focuses primarily on the individual regime under Article 91 LIRPF, as this is the most relevant for the HNW individuals and expatriates who are the primary audience of this publication.

The Four Conditions for CFC Attribution

The CFC rules under Article 91 LIRPF apply — and income is attributed to the Spanish resident — only when all four of the following conditions are satisfied:

Condition 1: Control (50% Threshold)

The Spanish resident must hold, directly or indirectly, alone or together with connected persons (spouse, ascendants, descendants, siblings, and their spouses), more than 50% of the capital, equity, voting rights, or income rights of the foreign entity.

The 50% test looks through chains of entities — if the Spanish resident controls a company that in turn holds shares in the offshore company, the indirect holding counts toward the 50% threshold. Connected persons' holdings are aggregated, so a family group collectively holding 60% of an offshore company (with one member holding 30%) will satisfy the control test for each member of the group.

Condition 2: Low Tax (75% of Spanish Tax)

The foreign entity must be subject to tax on its income at an effective rate of less than 75% of the tax that would have been due under Spanish law on the same income. This is calculated by reference to the Spanish corporate tax rate (25%) — the foreign entity must pay effective tax of less than 18.75% (i.e., 75% × 25%) to satisfy the low-tax condition.

Most offshore jurisdictions easily satisfy this condition: Cayman (0%), BVI (0%), Jersey (0% on non-Jersey income), Isle of Man (0% on non-IOM income), Panama (territorial tax, often 0% on non-Panamanian income) all satisfy it comfortably. Countries with competitive but not zero tax rates — Ireland (12.5%), Cyprus (12.5%), Bulgaria (10%) — also satisfy the condition. The UK (25%), Germany (around 30%), France (25%) and the Netherlands (25.8%) do not satisfy the low-tax condition, which means entities in these jurisdictions are generally outside the CFC rules.

Condition 3: Passive Income Categories

Not all income of the controlled foreign entity is attributed — only specified passive income categories. Under Article 91 LIRPF, the attributable income categories include:

• Dividends and profit participations
• Interest and other returns on financial instruments
• Royalties and income from intellectual property rights
• Capital gains from the sale of assets that are not connected to an active trade or business
• Income from financial leasing arrangements
• Income from insurance and re-insurance activities
• Income from invoicing for goods or services sold by related parties where no real value is added

Active trading income — revenues from genuine manufacturing, services, retailing, or other operational businesses — is generally not attributed under the CFC rules.

Condition 4: Nexus to Spain

The passive income attributed must be of a type that, if earned directly by the Spanish resident, would have been subject to Spanish taxation. This condition is generally straightforward but occasionally creates issues for income types with complex treaty or domestic exemptions.

Economic Substance Exemption

Even where all four conditions are satisfied, the CFC rules do not apply if the foreign entity carries out a genuine economic activity using its own means — that is, it has real staff, real premises, and real management decision-making in its jurisdiction. This is known as the actividad económica genuina (genuine economic activity) exemption.

AEAT's approach to this exemption is strict: it requires evidence of:

• At least one full-time employee (not merely a registered director) working in the jurisdiction
• Physical premises (not merely a registered office address at a law firm or company services provider)
• Board decisions and management decisions actually made in the jurisdiction (not managed from Spain)
• The passive income being genuinely ancillary to an active business (e.g., interest on working capital cash balances of a trading company), rather than the primary purpose of the entity

A pure holding company with no staff and no management activity in its jurisdiction does not qualify for the substance exemption, regardless of how much its advisers insist it has "substance."

EU/EEA Carve-Out: The Anti-Abuse Provision

The EU Anti-Tax Avoidance Directive (ATAD) and the European Court of Justice's jurisprudence (particularly the Cadbury Schweppes case) require that CFC rules applied within the EU do not interfere with the fundamental freedoms of the internal market. In response, Spain provides an important carve-out for entities located in EU/EEA member states:

For entities established in an EU or EEA member state, the CFC rules apply only if the structure is wholly artificial — established purely for the purpose of obtaining a tax advantage, with no genuine economic substance in the EU/EEA state. This is a higher threshold than for third-country entities (where the mere satisfaction of the four conditions above triggers attribution).

In practice, this means that an Irish holding company, a Dutch BV, or a Luxembourg SARL with genuine economic substance — real management, real staff, real premises in those jurisdictions — is very unlikely to be caught by Spain's CFC rules, even if it satisfies the control and low-tax conditions. The substance test is the critical battleground for EU/EEA entities.

The "Motivo Económico Válido" Test

Separate from the EU/EEA anti-abuse carve-out, Spain's general anti-avoidance framework (particularly the cláusula anti-abuso under the LIRPF and the general norm against abuse of law under the Ley General Tributaria) includes a valid economic reason test. Even where a structure technically avoids the CFC rules, AEAT can challenge it on the basis that its primary purpose is tax avoidance without a valid non-tax economic justification.

How AEAT Applies the CFC Rules in Practice

AEAT's approach to CFC enforcement involves several standard techniques:

• CRS data: Under the Common Reporting Standard, Spanish residents' offshore accounts and company interests are reported to AEAT automatically by financial institutions worldwide. This gives AEAT a comprehensive picture of offshore holdings
• Modelo 720 cross-referencing: Modelo 720 declarations (for foreign assets) are cross-referenced with IRPF returns to identify undeclared offshore income. Disparities trigger inspections
• Beneficial ownership registries: EU and many non-EU jurisdictions now maintain beneficial ownership registries that AEAT can access through international exchange of information requests
• Transfer pricing documentation: For corporate taxpayers, AEAT reviews transfer pricing documentation to identify controlled entities with passive income profiles

CFC Rules for Beckham Law Taxpayers

One of the significant advantages of the Beckham Law (Article 93 LIRPF) is its interaction with the CFC rules. Beckham Law taxpayers are treated as non-residents for IRPF purposes, and the CFC rules under Article 91 LIRPF technically do not apply to non-residents. This means that a Beckham Law taxpayer who controls an offshore entity with significant passive income is not subject to the CFC attribution rules during the Beckham period — provided the income remains outside Spain and is not distributed to the taxpayer.

However, this protection ceases when the Beckham period ends and the individual transitions to the general IRPF regime. From that point, the full CFC rules apply. Pre-exit planning — restructuring the offshore entity before the Beckham period expires — is essential to avoid a large CFC attribution in year 7.

Case Studies

Case 1: Irish Holding Company

A Spanish resident owns 100% of an Irish holding company (12.5% Irish corporate tax rate). The Irish company holds shares in operating subsidiaries and receives dividends from them. The Irish company has a managing director, a registered office with actual management meetings in Dublin, and makes genuine investment decisions there. Result: the EU/EEA carve-out applies. Provided the structure has genuine substance in Ireland (staff, premises, genuine management), the CFC rules do not apply. The dividends received by the Spanish resident from the Irish company are taxed in Spain at savings-income rates when distributed.

Case 2: Cayman Investment Fund Structure

A Spanish resident (the founder and 100% shareholder) controls a Cayman Islands exempted company that holds a portfolio of listed equities and bonds, earning dividends, interest and capital gains. Cayman tax rate: 0%. Result: all four CFC conditions are met (100% control, 0% Cayman tax, passive income, no substance). The dividends, interest and capital gains of the Cayman company are attributed to the Spanish resident annually in their IRPF return. The Spanish resident cannot defer these income items by retaining them in the Cayman company.

Case 3: Swiss AG as Licensing Vehicle

A Spanish resident owns 100% of a Swiss AG that licences intellectual property to Spanish and foreign operating companies. The Swiss AG pays Swiss corporate tax of approximately 12–15% (depending on canton). Swiss tax is below the 75% threshold (18.75%). The IP royalty income is passive. The Swiss AG has no real staff — just a registered address. Result: CFC rules apply. Royalty income is attributed to the Spanish resident annually. The genuinely low Swiss tax rate does not protect the structure — only genuine substance would.

Case 4: Cayman Fund (Institutional)

A Spanish resident holds an interest in a Cayman-domiciled hedge fund managed by an independent fund manager. The Spanish resident holds 5% of the fund. Result: the 50% control test is not satisfied (5% is well below 50%). The CFC rules do not apply. The Spanish resident is taxed only when distributions are received or when they sell their fund interest — not on the fund's underlying income as it accrues.
