BEPS Action 13 replaced a patchwork of jurisdiction-specific transfer pricing documentation rules with a coordinated three-tiered standard: the Master File, the Local File, and the Country-by-Country Report. Each serves a different audience and a different purpose, and the most common compliance failure is not missing any one of the three, but preparing them without reconciling the numbers and narrative across all three.
The Master File: The Group-Wide Blueprint
The Master File provides a high-level overview of the MNE group's global business, including its organisational structure, description of its business drivers, intangibles strategy, intercompany financing arrangements, and consolidated financial and tax positions. It is filed identically, or near-identically, in every jurisdiction the group operates in, which means any inconsistency between the group narrative it presents and the specific transactions described in a given country's Local File is immediately visible to that country's tax authority on a side-by-side read.
The Local File: Country-Specific Transaction Detail
The Local File supplements the Master File with information specific to the material controlled transactions of the local entity, including a detailed functional analysis, the transfer pricing method selected for each material transaction category, and the benchmarking analysis supporting it. Because the Local File is prepared separately in each jurisdiction, often by different local teams or advisors, functional descriptions can drift from the group-wide characterisation set out in the Master File if the two are not prepared and reviewed together.
Country-by-Country Reporting: The Risk-Assessment Trigger
CbCR, generally required for groups with consolidated revenue above the applicable threshold, most commonly seven hundred and fifty million euros, reports revenue, profit before tax, tax paid and accrued, headcount, and tangible assets on a per-jurisdiction basis. CbCR is explicitly designed as a high-level risk-assessment tool rather than a pricing justification in itself, but a jurisdiction showing disproportionately high profit relative to headcount and tangible assets is a well-established audit trigger, and tax authorities increasingly cross-reference CbCR figures against the narrative in the Master and Local Files for the same jurisdiction.
Where the Three Tiers Contradict Each Other
The most damaging documentation failure is internal inconsistency: a Master File describing centralised strategic decision-making at the parent, a Local File describing the same local entity as bearing meaningful entrepreneurial risk, and a CbCR showing that jurisdiction earning outsized profit relative to its reported headcount. Any reviewing tax authority reading all three together will identify the contradiction immediately, and a documentation package that fails on internal consistency undermines the credibility of even a technically sound benchmarking analysis contained within it.
Building a Coordinated Preparation Process
Groups that treat the three tiers as three separate compliance deliverables, prepared by different teams on different timelines, are structurally more exposed than groups that run a single coordinated process: draft the Master File narrative first, cascade the same functional characterisations into every Local File, and reconcile the CbCR figures against both before any of the three is finalised and filed. Building this sequencing into the annual compliance calendar, rather than treating each filing as an independent year-end task, is the single most effective structural fix available to a group with material cross-border operations.
Conclusion
The three-tiered documentation standard under Action 13 was designed to be read together, and tax authorities now do exactly that as a first step in risk assessment, well before opening a detailed transaction-level audit. A Master File, Local File, and CbCR that tell three subtly different stories about the same group is a more common and more damaging failure than any single weak benchmarking study, and it is entirely avoidable through coordinated preparation.
