Master File — The Master File is a standardized transfer pricing document that provides tax authorities with a high level overview of the multinational enterprise's (MNE) global business operations, transfer pricing policies, and income allocation.
The Master File is a standardized transfer pricing document that provides tax authorities with a high-level overview of the multinational enterprise's (MNE) global business operations, transfer pricing policies, and income allocation. Introduced under OECD BEPS Action 13, the Master File gives tax authorities the "big picture" context for evaluating transfer pricing in any specific jurisdiction.
The Master File is one component of the three-tiered documentation structure: Master File (global overview), Local File (country-specific details), and Country-by-Country Report (financial data by jurisdiction).
The OECD Transfer Pricing Guidelines (2022), Annex I to Chapter V, prescribe the Master File content. The Guidelines specify that the Master File should contain standardized information relevant for all MNE group members—providing an overview of the group's business, including global operations, transfer pricing policies, and allocation of income and economic activity.
Chapter V: Documentation at explains the Master File's purpose and content requirements.
BEPS Action 13 (2015) introduced the three-tiered documentation approach. The Master File should be available to all relevant tax administrations to provide context for Local File analysis.
Master File Contents (OECD Standard):
| Section | Content |
|---|---|
| Organizational Structure | Legal entity chart, geographic locations |
| Business Description | Principal activities, key profit drivers |
| Intangibles | IP ownership, R&D activities, transfer pricing for intangibles |
| Intercompany Financial Activities | Financing arrangements, treasury functions |
| Financial and Tax Positions | Consolidated financials, APAs, rulings |
Key Characteristics:
Consistency is Critical: The Master File is shared with multiple tax authorities who may exchange information. Ensure descriptions of functions, risks, and policies are consistent and supportable in every jurisdiction.
MNE Structure: US parent with subsidiaries in Germany, UK, and Mexico
Master File Contents:
| Section | Example Content |
|---|---|
| Org Chart | USCo (Parent) → GermanCo, UKCo, MexicoCo |
| Business Description | Consumer electronics manufacturing and distribution |
| Value Chain | R&D (US) → Manufacturing (Mexico) → Distribution (Germany, UK) |
| IP Ownership | All patents and trademarks owned by USCo |
| TP Policies | Cost-plus for manufacturing, resale margin for distribution |
| Financing | Centralized treasury in US, intercompany loans at SOFR+200bps |
| Aspect | Master File | Local File |
|---|---|---|
| Scope | Entire MNE group | Single jurisdiction |
| Perspective | Global overview | Transaction-specific detail |
| Preparer | Headquarters/central TP team | Local entity/advisors |
| Content | Policies, structure, global allocation | Benchmarking, specific transactions |

Requirements vary by jurisdiction. Many countries have adopted BEPS Action 13 and require Master Files for MNEs above certain thresholds (often based on consolidated revenue). Countries like Germany, UK, Australia, and many others require Master Files. Check specific local requirements—thresholds and deadlines differ.
Common thresholds range from €50M to €750M consolidated group revenue, depending on jurisdiction. Some countries have lower thresholds or no threshold. The OECD suggested €750M as the CbCR threshold, but Master File thresholds are set locally.
The Master File should provide sufficient context for tax authorities to understand your global operations and TP policies, but it's not meant to replace Local File detail. Think "overview" not "exhaustive analysis." Typically 20-50 pages depending on group complexity.
Many jurisdictions accept English Master Files, but some require local language translation. Check specific country requirements. Some accept English with a local language summary.
Annually, or when material changes occur (restructurings, new business lines, significant acquisitions). Most jurisdictions require the Master File to reflect the fiscal year under review. Some allow using prior-year Master Files with updates.
Inconsistencies raise red flags for tax authorities, who may exchange information. Ensure the Master File's descriptions of functions, risks, and policies align with Local File detail. Discrepancies can trigger audits and credibility challenges.
Typically headquarters or the central TP team, sometimes with support from external advisors. Local subsidiaries provide input on their operations. Centralized preparation ensures consistency across the global description.
