Transfer Pricing Declaration Mexico (Declaración de Partes Relacionadas)

The Transfer Pricing Declaration Mexico (Declaración de Partes Relacionadas) is the comprehensive tax documentation package that Mexican taxpayers with transactions involving related parties (partes relacionadas) located outside Mexico must prepare and maintain under Articles 76-A and 179 through 184 of the Ley del Impuesto sobre la Renta (LISR), published in the Diario Oficial de la Federación on 11 December 2013 and substantially reformed by the Decreto de reformas fiscales published on 18 November 2015 implementing the OECD's Base Erosion and Profit Shifting (BEPS) Action 13 recommendations. The declaration encompasses the three-tiered documentation framework: the Master File (Archivo Maestro — Forma 76-A), the Local File (Archivo Local — Forma 76-A), and the Country-by-Country Report (Informe País por País — Forma 76-A CbCR).

Article 179 LISR establishes the fundamental arm's length principle (principio de plena competencia) governing all transactions between related parties: prices, fees, and consideration agreed between related parties must correspond to those that would be agreed between independent parties in comparable transactions under comparable circumstances (operaciones comparables). Mexico's related-party definition under Article 179 LISR encompasses: legal entities under common control (one party controls the other, or both are controlled by a third entity); individuals and legal entities with a more than 50% ownership interest in each other; members of the same tax consolidation group (grupo empresarial); transactions with residents of preferential tax regimes (REFIPRES under Articles 176 through 179 LISR); and permanent establishments (establecimientos permanentes) and their head offices.

The six transfer pricing methods recognised under Article 180 LISR align with the OECD Transfer Pricing Guidelines adopted by Mexico through its commitments under the Inclusive Framework on BEPS: the Comparable Uncontrolled Price method (Precio Comparable No Controlado — CUP / PCN); the Resale Price method (Precio de Reventa — PR); the Cost Plus method (Costo Adicionado — CA); the Transactional Net Margin method (Márgenes Transaccionales de Utilidad de Operación — MTUO); the Profit Split method (Partición de Utilidades — PU); and the Residual Profit Split. The LISR establishes a priority ordering: the PCN method is preferred where comparables exist; the other methods apply in the order listed when the PCN method cannot be applied reliably.

The Article 76-A LISR obligation — introduced as part of Mexico's BEPS implementation in the Decreto of 18 November 2015 — requires the following from Mexican constituent entities (entidades constitutivas) of multinational enterprise (MNE) groups with consolidated annual revenue above MXN 12,000 million (approximately USD 600 million): annual filing of the Informe País por País (Country-by-Country Report — CbCR / Forma 76-A) with the SAT by 31 December of the year following the fiscal year, disclosing revenue, profit, taxes paid, employee headcount, and assets by jurisdiction for all group entities. Intermediate entities and surrogate filers for Mexican-based MNE groups with Mexican ultimate parent entities meeting the threshold must also file. The CbCR is exchanged between tax authorities under the Multilateral Competent Authority Agreement on the Exchange of CbCR reports (MCAA-CbCR) to which Mexico acceded through the OECD/G20 Inclusive Framework.

The Master File (Archivo Maestro) and Local File (Archivo Local) under Article 76-A LISR must be prepared contemporaneously with the filing of the annual ISR return and submitted to the SAT upon request or within the deadlines established in the Resolución Miscelánea Fiscal. The SAT's transfer pricing audit programme — coordinated through the Administración General de Grandes Contribuyentes (AGGC) — uses CbCR data, financial CFDI data, and DIM informative return data to identify high-risk related-party transaction patterns and select targets for formal audits (visitas domiciliarias de precios de transferencia).

A Transfer Pricing Declaration Mexico is required from Mexican taxpayers engaged in transactions with foreign related parties during the fiscal year, subject to the documentation and filing thresholds established by LISR Articles 76, 76-A, and 179.

The declaration is needed by any Mexican legal entity (persona moral) or individual with business activities (persona física con actividad empresarial) that conducted transactions in the fiscal year with parties resident outside Mexico with whom a related-party relationship exists under Article 179 LISR — including payments for royalties, management services, shared services, technology licences, intercompany loans, distribution margins, manufacturing tolling arrangements, and asset transfers. Article 76 Section IX LISR requires annual disclosure of related-party transaction details in the DIM informative return by 28 February of the following year.

Contemporaneous transfer pricing documentation under Article 76 Section XII LISR must be prepared and maintained regardless of filing deadlines — this means the economic analysis supporting the arm's length nature of each material related-party transaction must be completed no later than the annual ISR return filing date (31 March for most legal entities, 30 April for individuals). The documentation requirement applies when the aggregate value of all related-party transactions during the year exceeds the materiality thresholds published in the Resolución Miscelánea Fiscal, which reference the transaction's value relative to the taxpayer's total operations.

The Archivo Maestro (Master File) must describe the overall multinational group structure, value chain, intangibles policy, intercompany financing arrangements, and consolidated financial performance. The Archivo Local (Local File) must document each material related-party transaction involving the Mexican entity specifically — the transaction description, counterparty details, functional analysis, benchmarking study using comparable data from databases such as Bureau van Dijk's Amadeus or Orbis, the most appropriate transfer pricing method under Article 180 LISR, and the arm's length range (rango de plena competencia) demonstrating that the agreed price falls within the interquartile range of comparables.

The Country-by-Country Report (Informe País por País) under Article 76-A LISR is required when the Mexican entity is the ultimate parent or a surrogate parent of an MNE group with consolidated annual revenue of MXN 12,000 million or more. The CbCR must be filed with the SAT electronically by 31 December of the fiscal year following the year reported, using the SAT's portal systems. Mexican constituent entities of foreign-headquartered MNE groups that file their CbCR in the parent company's jurisdiction benefit from the exchange agreement — but must notify the SAT of the identity of the filing entity through the corresponding notification mechanism in the Resolución Miscelánea Fiscal.

Failure to maintain contemporaneous transfer pricing documentation exposes the taxpayer to: SAT transfer pricing adjustments under Article 91 LISR (presumptive income); fines of 0.5% to 1.5% of the related-party transaction value under Articles 81–82 CFF for late or inadequate filing; and potential criminal penalties for deliberate misreporting under Articles 108–110 CFF.

A complete Transfer Pricing Declaration Mexico under LISR Articles 76-A and 179–184 must incorporate the following components to meet SAT documentation standards and defend against transfer pricing adjustments.

Related Party Identification: Full identification of each foreign related party involved in material transactions — corporate name, country of incorporation, country of tax residence, foreign tax ID, percentage of ownership or control relationship with the Mexican entity, and a description of the related-party relationship under Article 179 LISR. A corporate group organisational chart showing the ownership structure must accompany the documentation.

Transaction Description: Detailed description of each category of related-party transaction during the fiscal year — services, royalties, interest, goods, intangibles, financial guarantees, or other — specifying the transaction amounts in MXN (converted from foreign currency at Banco de México rates under Article 20 CFF), the currency of original transaction, and the contractual terms governing each transaction category.

Functional Analysis (Análisis Funcional): A comprehensive analysis of the functions performed, assets employed, and risks assumed (FAR analysis) by each party to each related-party transaction. The functional analysis identifies which entity performs the economically significant functions — product development, manufacturing, distribution, marketing, after-sales service — and which entity bears the material risks — market risk, credit risk, inventory risk, currency risk, product liability risk — determining how residual profit should be allocated within the group under the OECD's revised BEPS-compliant guidance.

Comparable Selection and Benchmarking: Identification of comparable uncontrolled transactions or companies using public databases (Amadeus, Orbis, or equivalent) following the SAT's accepted search methodology. The benchmarking study must: define the tested party; select the most appropriate transfer pricing method under Article 180 LISR; apply the method using a multi-year analysis (three to five year weighted average margins) to mitigate annual fluctuations; construct the arm's length range (rango de plena competencia) using the interquartile range of the comparable set; and demonstrate that the Mexican entity's actual margin falls within that range. Where the margin falls outside the range, a price adjustment must be made in the annual ISR return.

Master File (Archivo Maestro): A group-level document describing the MNE group's global business, organisational structure, value chain, significant intangibles (patents, trademarks, know-how, customer relationships), intercompany financing policy, consolidated financial statements for the fiscal year, and a list of all existing advance pricing agreements (APAs — Acuerdos Anticipados de Precios) and other rulings affecting related-party transactions. The Master File follows the OECD's Annex I to Chapter V of the Transfer Pricing Guidelines as implemented in Mexico's Resolución Miscelánea Fiscal.

Local File (Archivo Local): A Mexico-specific document for each material related-party transaction, containing the transaction description, contracts governing the transaction, intercompany agreements, financial data for the tested party, the functional analysis, the benchmarking study, and the selected transfer pricing method with quantitative support showing arm's length compliance. The Local File follows the OECD's Annex II to Chapter V of the Transfer Pricing Guidelines.

Country-by-Country Report (Informe País por País): For qualifying MNE groups meeting the MXN 12,000 million revenue threshold, the CbCR must disclose for each jurisdiction where the group operates: aggregate revenue (intragroup and third-party); pre-tax profit or loss; income tax paid and accrued; stated capital; accumulated earnings; number of employees; and tangible assets. The SAT uses CbCR data as a risk assessment tool and exchanges it with treaty partners through the MCAA-CbCR network.

Forms-legal.com provides this Transfer Pricing Declaration Mexico template as an administrative framework document. All transfer pricing documentation — including functional analyses, benchmarking studies, and CbCR reports — must be prepared by a Contador Público Certificado (CPC) or transfer pricing specialist with expertise in OECD Transfer Pricing Guidelines, LISR Articles 179–184, and the SAT's current Resolución Miscelánea Fiscal. Contemporaneous documentation is the strongest defence against SAT transfer pricing adjustments and associated surcharges under Articles 17-A and 21 CFF.
