Tax advisor in Madrid — enterprise-grade fiscal planning at the centre of Spain's corporate economy

Madrid: Spain’s corporate tax capital

Spain’s corporate fiscal machinery is centred in Madrid. The Agencia Estatal de Administracion Tributaria (AEAT) has its national headquarters in Calle Infanta Mercedes. The Delegacion Central de Grandes Contribuyentes — Spain’s large taxpayer unit, responsible for inspecting groups above EUR 100 million in revenue — operates from the capital. The Tribunal Economico-Administrativo Central (TEAC), the first mandatory stage of administrative appeal against AEAT decisions, sits in Madrid. When corporate tax disputes in Spain reach judicial review, they go before the Audiencia Nacional and ultimately the Tribunal Supremo, both in Madrid.

For a group with material Spanish operations, being advised by a Madrid tax team with direct AEAT inspection and TEAC appeal experience is not a convenience — it is a structural advantage. BMC’s Madrid office, located in the Barrio de Salamanca at C/ Castello 36, Planta 1, is the firm’s national corporate tax centre and the team that manages the most complex group mandates.

Services for multinational groups operating from Madrid

The tax advisory needs of a multinational operating from Madrid span the full corporate tax lifecycle. At the planning stage: the optimal Spanish holding structure, the application of the Participation Exemption and the ETVE regime, the design of intercompany financing within Spain’s interest limitation rules, and the transfer pricing framework that governs transactions between the Spanish entities and the wider group. At the compliance stage: Impuesto sobre Sociedades preparation and filing, transfer pricing documentation (local file, master file, CbCR), related-party transaction reporting under modelo 232, and IS instalment payments. At the controversy stage: AEAT inspection management, technical defence preparation, administrative appeal before the TEAC, and judicial review before the Audiencia Nacional.

BMC handles all three stages. Our Madrid tax team includes corporate tax lawyers, economists qualified to issue binding transfer pricing reports, and former AEAT officials with direct inspection experience. For large group clients, we provide a dedicated senior partner as single point of contact across all tax matters, including coordination with the group’s home-country advisors on cross-border positions.

AEAT inspections and tax litigation in Madrid

An AEAT inspection of a large Madrid company is a sustained, technically demanding process. The Unidad de Gestion de Grandes Empresas or the Delegacion Central assigns experienced inspectors who focus on high-value issues: transfer pricing, the Participation Exemption, the reality of IS deductions, the substance behind holding and royalty structures, and the tax treatment of complex financial instruments. The process can run for years, and the technical and procedural decisions made in the first months — what information to provide, how to characterise contested positions, whether to regularise voluntarily — have decisive consequences for the final outcome.

BMC brings three capabilities that matter in this context. First, technical depth: our Madrid tax team produces the transfer pricing studies, economic analyses, and legal memoranda that defend contested positions with the rigour the AEAT and TEAC demand. Second, procedural experience: we understand the AEAT’s internal procedures, the mandatory timelines, the rights of the taxpayer during inspection, and the mechanics of the administrative appeal system. Third, strategic judgment: we advise clients when to regularise a position early, when to contest, and how to sequence a multi-issue dispute across the administrative and judicial stages to maximise the overall outcome.

For groups that have received an AEAT notification and need immediate specialist support, BMC Madrid is available for urgent engagement regardless of whether a prior advisory relationship exists.

International tax planning from Madrid

Madrid’s position as Spain’s gateway for international capital makes it the natural base for inbound investment structuring and outbound group reorganisations. Spain’s treaty network of over 100 double taxation agreements, combined with the ETVE regime and the Participation Exemption, creates a competitive platform for holding structures, regional headquarters, and intra-European royalty and finance flows when correctly structured with appropriate substance.

BMC advises international clients on the full inbound investment cycle: pre-entry analysis of the Spanish tax landscape, design of the acquisition or greenfield structure (direct versus corporate vehicle, debt-equity mix, intercompany financing terms), establishment of the Madrid entity with the substance required to access treaty benefits and the Participation Exemption, and ongoing IS planning to manage the effective tax rate of the Spanish operations.

For groups considering Madrid as a European HQ location — attracted by the combination of the ETVE regime, Spain’s treaty network, competitive talent costs, and the time zone advantage for managing both Americas and European operations — BMC provides a comprehensive HQ migration advisory, from the structural mapping and exit tax analysis in the current HQ jurisdiction to the full setup of the Madrid entity and its tax compliance infrastructure.

Our Madrid office is reachable at madrid@bm.consulting and +34 910 917 811. Initial consultations are available in English, Spanish, German, and French.

Key Spanish corporate tax provisions that Madrid groups use

The corporate tax landscape for groups managed from Madrid includes several provisions that, when correctly applied, materially reduce the effective tax rate on Spanish operations:

Capitalisation reserve (reserva de capitalización, Art. 25 LIS). Companies that retain profits and transfer them to a non-distributable reserve can deduct 15% of the increase in net equity from their IS taxable base. For a company generating €10 million in taxable income and retaining €4 million in the year, the capitalisation reserve deduction reduces taxable income by €600,000 — a real tax saving of €150,000. No specific investment is required; the benefit is simply for retaining earnings.

R&D and technological innovation deduction (Art. 35 LIS). Spain’s R&D deduction is among the most generous in Europe: 25% of R&D expenditure (42% if expenditure exceeds the prior two-year average) and 12% of technological innovation expenditure. For Madrid technology companies, pharmaceutical groups, and industrial companies with significant R&D budgets, this deduction can reduce IS to near-zero and generate credits that carry forward indefinitely. Crucially, qualifying credits exceeding the annual tax liability can be monetised (subject to conditions) via a 20% cash rebate from the AEAT.

IS group consolidation regime (Régimen Especial de Consolidación Fiscal, Art. 55-75 LIS). Groups of Spanish entities (where the parent holds at least 75% of subsidiaries) can elect to file a consolidated IS return, offsetting profits of profitable entities against losses of loss-making ones. This is the primary tax efficiency tool for complex Spanish sub-groups managed from Madrid — typically resulting in a significantly lower total IS liability than filing individual returns.

Interest limitation rule (Art. 16 LIS) — planning the structure. Spain caps net financial expense deductibility at 30% of operating EBITDA or €1 million, whichever is higher. For Madrid groups with significant intercompany financing — acquisition debt from PE investors, intragroup loans, factoring and reverse factoring with related parties — the deductibility cap must be modelled in advance. Distributing the deductible capacity across group entities through the consolidation regime, restructuring loan tenor and payment terms, and timing capital raising to manage the EBITDA reference period are all legitimate tools BMC employs in this planning.

The ETVE regime: Spain’s holding company framework for international groups

The Entidad de Tenencia de Valores Extranjeros (ETVE) regime — established under Articles 107-108 of the Ley del Impuesto sobre Sociedades — provides a purpose-built holding company framework for Spanish entities that own foreign subsidiaries. When correctly structured, the ETVE regime combined with the Participation Exemption creates one of the most competitive holding structures in Western Europe.

The key features of the ETVE regime are:

Participation Exemption (Art. 21 LIS) on dividends and capital gains. Dividends received from and capital gains on the disposal of foreign subsidiaries (where the Spanish entity holds at least 5% for at least one year and the subsidiary is not in a low-tax jurisdiction) are 95% exempt from Impuesto sobre Sociedades. The remaining 5% is taxed at 25%, resulting in an effective tax rate of 1.25% on qualifying dividend and gain income.

Non-resident withholding exemption on distributions. Dividends and capital gains paid by the ETVE to non-resident shareholders are generally exempt from Spanish withholding tax — provided the distributions correspond to income that benefited from the Participation Exemption within the ETVE. This makes the ETVE transparent for non-resident shareholders receiving income that originated from qualifying foreign subsidiaries.

Treaty access. The ETVE is a Spanish tax resident company and therefore has access to Spain’s treaty network of over 100 double taxation agreements. For groups from countries with limited treaty networks of their own, routing Spanish holding operations through the ETVE provides access to Spain’s treaties for their European and Latin American subsidiary dividends.

The ETVE regime has substance requirements that must be met genuinely — a Spanish holding company without real decision-making, personnel, and management in Spain risks challenge on Pillar Two grounds, treaty access, and the anti-abuse provisions of the Parent-Subsidiary Directive. BMC advises on establishing and maintaining the operational substance that makes the ETVE regime defensible under modern anti-avoidance standards.

Expat tax advisory in Madrid: Beckham Law for corporate executives

Madrid’s position as Spain’s corporate capital means it attracts a significant number of senior executives and highly qualified professionals relocating from the UK, Germany, France, the US, and other international markets. For these individuals, the Beckham Law (Art. 93 LIRPF, reformed by the 2022 Startups Law) is the most significant tax planning tool available.

For a foreign executive relocated to Madrid by a multinational group, the Beckham Law provides:

• Flat 24% rate on Spanish-source employment income up to €600,000 (instead of up to 47% under the standard progressive scale)
• Worldwide investment income (dividends, interest, capital gains) excluded from the Spanish tax base during the regime period — taxed only at savings-scale rates on Spanish-source investment income
• Six-year regime duration (year of arrival plus five years)

The application (Modelo 149) must be filed within six months of Social Security registration or the commencement of work in Spain. Late applications are not accepted. BMC manages the Beckham Law application process for Madrid-based executives from initial eligibility assessment through AEAT approval, coordinating with the executive’s employer’s HR and international mobility team where required.

For executives approaching the end of their Beckham Law period — in year five or six — we also advise on the post-Beckham tax position in Spain, including whether continued Spanish residency is optimal given the transition to the standard progressive IRPF scale, and whether pre-transition planning steps (restructuring investment portfolios, timing capital gains realisations, reviewing pension arrangements) can reduce the tax impact of the regime end.
