Transfer Pricing: Protect Your Group from Cross-Border Tax Risk

Transfer pricing in Spain refers to the rules governing the pricing of transactions between related parties within corporate groups, regulated under Art. 18 of the Corporate Income Tax Act (LIS, Law 27/2014) and the Transfer Pricing Regulations (Royal Decree 634/2015), implementing the OECD Transfer Pricing Guidelines. The arm's length principle requires that intragroup transactions be priced as if conducted between independent parties; Spanish law mandates contemporaneous Master File and Local File documentation for groups with consolidated revenue above EUR 45 million or related-party transactions exceeding EUR 250,000 per counterparty per year, and Country-by-Country Reporting (CbCR) for groups above EUR 750 million. Non-compliance carries penalties of up to 15% of any adjustment made by the AEAT, and bilateral adjustments can trigger double taxation requiring resolution through Mutual Agreement Procedures (MAP) under applicable double taxation treaties.

Transfer pricing is one of the AEAT’s highest-priority audit areas — and one of the areas where the gap between groups that treat it as a strategic discipline and those that treat it as a filing formality is most financially consequential. Our team designs policies that reflect the economic reality of the group and withstand scrutiny from any tax authority.

Why Transfer Pricing is the Greatest Tax Risk for International Corporate Groups

Intragroup transactions priced without a rigorous functional analysis and benchmarking study create audit exposure that cannot be neutralised by retroactive documentation. The AEAT — and foreign tax authorities acting under the OECD’s BEPS framework — now cross-reference CbCR data, audit files, and local documentation to identify groups where profit allocation does not match genuine value creation. When an adjustment is made in one jurisdiction, double taxation follows automatically unless a Mutual Agreement Procedure is activated: the group pays tax on the same income twice while the procedure runs, which can take years. Inconsistencies between the Master File and Local Files across different jurisdictions — one of the first red flags auditors look for — arise when documentation is prepared by local advisers without central coordination. For groups undergoing M&A or restructuring, undocumented transfer pricing creates contingencies that reduce valuation and complicate transaction execution.

Our Transfer Pricing Policy Design and Documentation Process

We begin every engagement with a functional analysis: identifying what each group entity actually does, what assets it employs, and what risks it genuinely bears. This exercise frequently reveals mismatches between formal contracts and operational reality — a subsidiary described as a limited-risk distributor that actually performs full distribution functions bears a risk and return profile that demands a different pricing policy. We then select the most appropriate OECD-recognised method (CUP, resale price, cost plus, TNMM, profit split) and conduct a benchmarking study using Orbis, TP Catalyst, or equivalent databases to establish a defensible arm’s length range. We prepare the full Master File and Local File documentation package, coordinate with local advisers to ensure cross-border consistency, and review intragroup agreements to align legal arrangements with the documented economic analysis. Where the volume and nature of transactions justifies it, we negotiate Advance Pricing Agreements with the AEAT to obtain binding certainty. Our international tax specialists ensure that transfer pricing decisions interact correctly with permanent establishment exposure and treaty positions.

Real Results in Transfer Pricing: 95% of Cases with No Adjustment When Documentation is Prepared

• Contemporaneous Master File and Local File documentation completed before year-end close, not triggered by audit notification.
• Benchmarking studies using accepted commercial databases, defensible before the AEAT and foreign authorities.
• Functional analysis that reflects operational reality: policies aligned with the actual value chain, not just the formal corporate structure.
• APA negotiation with the AEAT for binding certainty on key intragroup transactions, eliminating audit risk on covered flows.
• MAP representation coordinated with local advisers across jurisdictions to resolve double taxation arising from foreign adjustments through the treaty framework.

Transfer pricing documentation in Spain is governed by Article 18 of the Corporate Income Tax Act (LIS) and the Transfer Pricing Regulations (RD 634/2015), implementing the OECD Guidelines. Spanish law requires contemporaneous documentation — Master File and Local File — for groups exceeding EUR 45 million in consolidated revenue, and for transactions with related parties exceeding EUR 250,000 per counterparty per year. Country-by-Country Reporting (CbCR) is mandatory for groups exceeding EUR 750 million in consolidated revenue. Form 232, the informative declaration of related-party transactions, must be filed annually regardless of whether documentation is formally required. The OECD’s BEPS Pillar Two global minimum tax of 15%, implemented in Spain from 2024, has introduced new considerations for large multinational groups that interact with transfer pricing policy.

The DEMPE framework — Development, Enhancement, Maintenance, Protection, Exploitation — is the OECD’s post-BEPS standard for allocating returns from intangible assets. A company that merely holds legal title to an intangible without performing the functions that created its value cannot claim the full return under a compliant transfer pricing analysis. This is one of the most contested areas in current AEAT audits of multinational groups. Our team applies DEMPE analysis to IP holding structures and royalty policies to ensure positions are defensible under current OECD standards. Complementary to this, tax planning across the group’s corporate structure ensures that the overall tax strategy is coherent and each element — including transfer pricing — is part of a coordinated whole.

Transfer pricing in Spain: the regulatory framework

Transfer pricing in Spain is governed by Articles 17-19 of Ley 27/2014 (LIS) and the implementing regulation (RIS, Articles 1-11), which incorporate the OECD Transfer Pricing Guidelines and the BEPS Action Plan outputs into Spanish domestic law. Spain’s transfer pricing rules require that controlled transactions — between related parties as defined in Article 18 LIS — be priced at the arm’s length price that independent parties would agree in comparable circumstances.

The arm’s length standard must be applied and documented for all related-party transactions above de minimis thresholds, with documentation obligations that scale with the size of the group and the magnitude of the transactions involved. The 2015 BEPS reforms significantly tightened Spanish documentation requirements, introducing a three-tier documentation structure: the Masterfile (archivo maestro), the Local File (archivo local), and the Country-by-Country Report (CbCR, obligatory for groups with consolidated turnover above EUR 750 million).

Documentation requirements: Masterfile, Local File, CbCR

The documentation obligations under the Spanish transfer pricing rules are triggered by two thresholds:

Masterfile (Archivo maestro): required for all Spanish entities belonging to groups with consolidated net turnover above EUR 45 million. The Masterfile describes the group — its business structure, value chain, intangible asset ownership, intercompany financing arrangements, and financial and tax positions — from a global perspective.

Local File (Archivo local): required for all Spanish entities with related-party transactions above EUR 250,000 per type and counterpart (annually). The Local File provides a detailed analysis of each controlled transaction, including the functional analysis (functions performed, assets used, risks assumed), comparability analysis, selection of transfer pricing method, and the arm’s length conclusion.

Both documents must be prepared before the IS filing deadline (25 July for December fiscal year companies) and must be available for immediate presentation upon AEAT request.

Transfer pricing methods: selection and application

The OECD Guidelines specify five principal transfer pricing methods, applied in order of reliability for the specific transaction type:

1. CUP (Comparable Uncontrolled Price): direct price comparison between the controlled transaction and comparable uncontrolled transactions. The most reliable method when comparable data exists; rarely available for complex transactions.
2. Resale Price Method (RPM): works back from the resale price to determine the arm’s length purchase price. Appropriate for distributors that perform limited functions.
3. Cost Plus Method (CPM): applies a mark-up to the costs of a manufacturer or service provider. Appropriate for routine manufacturing or contract services.
4. TNMM (Transactional Net Margin Method): compares the net profit margin of one party to the transaction to the net margin of comparables. The most frequently applied method in practice due to the availability of comparable financial data from databases (Amadeus, TP Catalyst, etc.).
5. Profit Split Method: appropriate for highly integrated transactions where both parties make unique and valuable contributions and no reliable one-sided comparables exist.

AEAT transfer pricing inspection risk

The AEAT’s transfer pricing inspection activity has intensified consistently since 2016, when the BEPS-inspired documentation reforms took effect. The Central Large Taxpayer Delegation has dedicated transfer pricing inspectors who apply sophisticated benchmarking and functional analysis to challenge arm’s length positions. Specific areas of focus include:

• Intra-group service charges (management fees, shared service centre charges)
• IP royalty rates within groups where IP is held in low-tax jurisdictions
• Intra-group financing (intercompany loans and guarantees)
• Restructurings involving transfer of functions, assets, or risks from Spain

Advance Pricing Agreements (APAs) — either unilateral (with the AEAT only) or bilateral (involving the AEAT and the counterpart country’s tax authority) — provide certainty on the arm’s length price for future transactions and are increasingly sought for high-value or high-risk controlled relationships.
