Double taxation in Spain for businesses

Double taxation in Spain for businesses: how companies avoid paying tax twice

A German group receives dividends from its Spanish subsidiary. The Spanish company has already paid 25% corporate income tax on those profits. Now Germany wants to tax the dividends again. Without a treaty or EU Directive, the same profit is taxed twice — once in Spain, once in Germany. This is the double taxation problem for businesses. And unlike for individuals, companies have more tools available to solve it. Here is how they work.

Double taxation for businesses occurs when the same income or profit is subject to tax in two or more jurisdictions — typically the country where the income is earned and the country where the company receiving it is based. Spain has three main mechanisms to prevent this: double taxation treaties, the participation exemption, and the ETVE holding regime.

How double taxation affects businesses operating in Spain

For companies with cross-border operations, double taxation can arise in several ways:

• A foreign company receives dividends from its Spanish subsidiary: taxed in Spain (CIT on the subsidiary’s profit) and potentially taxed again in the parent’s home country on the dividend received
• A Spanish company receives interest or royalties from a foreign group company: withholding tax in the source country plus corporate income tax in Spain
• A foreign company sells shares in a Spanish holding company: potential capital gains tax in both Spain and the seller’s home country
• A company creates a permanent establishment in Spain: profits attributed to the PE are taxed in Spain, and the same profits may also be taxed in the parent’s home country without a relief mechanism

Mechanism 1: Spain’s double taxation treaties

Spain has signed over 100 bilateral double taxation treaties (DTTs) — covering virtually all major investment partner countries. For businesses, the key treaty provisions are:

• Reduced withholding rates on dividends: typically 5–15% for corporate shareholders (vs. 19% under domestic Spanish law)
• Reduced withholding on interest: typically 10% (vs. 19% domestic)
• Reduced withholding on royalties: typically 4–10% depending on the treaty (vs. 24% domestic)
• Capital gains allocation: most treaties assign taxing rights on share gains to the seller’s country of residence, eliminating Spanish capital gains tax for non-resident sellers (except for real estate-heavy companies)
• Permanent establishment definition: the treaty defines when the foreign company has a taxable presence in Spain — and what is excluded
• Mutual Agreement Procedure (MAP): a mechanism for the two tax authorities to resolve disputes about whether income has been taxed in accordance with the treaty

To apply treaty benefits, companies must provide a valid certificate of tax residence to the Spanish paying entity. Without it, domestic rates apply.

Mechanism 2: the participation exemption (exención por doble imposición)

Spain’s participation exemption is the primary domestic tool for eliminating double taxation on corporate dividends and capital gains. It applies when:

• A Spanish company holds at least 5% of another company’s capital — or the participation has an acquisition cost above €20 million
• The minimum shareholding has been held for at least 1 year
• The subsidiary is subject to a nominal corporate tax rate of at least 10% in its country of residence (or benefits from a tax treaty with Spain that includes an exchange of information clause)

When these conditions are met, 95% of the dividends received from the subsidiary are exempt from Spanish CIT. The remaining 5% is taxed at 25% — resulting in an effective rate of 1.25% on qualifying dividends. The same 95% exemption applies to capital gains from the qualifying shareholding.

This exemption applies to both domestic and foreign subsidiaries — making Spain competitive for international holding structures.

Mechanism 3: EU Directives

For companies within the EU, the following Directives provide additional relief that may go beyond what the treaty offers:

EU Parent-Subsidiary Directive

Dividends paid by a Spanish subsidiary to an EU parent company that holds at least 5% of the Spanish company’s shares for at least 1 year are exempt from Spanish withholding tax at source — 0%, regardless of whether a treaty exists or what the treaty rate would be. The Directive eliminates withholding entirely for qualifying intra-EU dividend flows.

EU Interest and Royalties Directive

Interest and royalties paid between associated EU companies (with 25%+ shareholding held for at least 2 years) are exempt from withholding tax at source. A Spanish company paying royalties to an EU parent under a qualifying licence agreement pays 0% withholding — eliminating one of the most significant double taxation risks for IP-holding structures.

Mechanism 4: the ETVE holding regime

Spain’s ETVE (Entidad de Tenencia de Valores Extranjeros) is a special regime for Spanish holding companies whose main purpose is holding shares in non-resident companies. The ETVE combines the participation exemption with a unique feature: zero Spanish withholding on distributions to non-resident shareholders when those distributions come from exempt income.

For a multinational group, this creates a structure where:

• Dividends from foreign subsidiaries enter the Spanish ETVE largely tax-free (95% exemption)
• The ETVE redistributes those dividends to its non-resident shareholders with 0% Spanish withholding
• The Spanish ETVE accesses Spain’s 100+ treaty network to reduce withholding in the source countries of its subsidiaries

This makes Spain one of the most efficient intermediate holding locations in Europe — particularly for groups with Latin American operations.

Permanent establishment and double taxation

A foreign company operating in Spain through a permanent establishment (PE) faces a specific double taxation risk: Spain taxes the profits attributed to the PE at 25% CIT, and the home country may also tax the same profits under its worldwide taxation system. Relief mechanisms include:

• Tax credit in the home country for Spanish CIT paid by the PE
• Exemption method under the applicable treaty (Spain allocates exclusive taxing rights over PE profits to Spain)
• Conversion of the PE into a subsidiary (which then benefits from the participation exemption and EU Directives)

The appropriate relief method depends on the applicable treaty and the home country’s domestic rules.

Frequently asked questions

Can a company rely on both a treaty and the EU Directives?

Yes. A company can apply whichever mechanism provides the most favourable outcome — as long as the conditions for that mechanism are met. In practice, EU Directives typically provide better results than treaties for intra-EU flows (0% vs. reduced treaty rates), while treaties are the primary tool for flows with non-EU countries. The two mechanisms are complementary, not mutually exclusive.

What is the Multilateral Instrument (MLI) and how does it affect Spanish treaties?

The OECD Multilateral Instrument (MLI) modified many of Spain’s tax treaties as part of the BEPS project. Key changes include: a principal purpose test (PPT) that denies treaty benefits where the main purpose of an arrangement is to obtain those benefits, and an expanded dependent agent PE rule. Spain has applied the MLI to most of its major treaties. Companies structuring cross-border flows through Spain must ensure their arrangements have genuine economic substance — pure tax-driven structures without business rationale are now at risk of treaty denial.

What happens if there is no treaty between Spain and the parent’s country?

Without a treaty, Spain applies its domestic rules: 19% withholding on dividends, 19% on interest, 24% on royalties paid to non-residents. Spain’s domestic participation exemption still applies to exempt dividends at the corporate level. The non-treaty country must provide its own relief mechanism (tax credit or exemption) to avoid double taxation on its end — which varies widely by jurisdiction.

Double taxation planning for businesses in Spain requires combining treaty analysis, the participation exemption, EU Directives, and holding structure design.
