The OECD Transfer Pricing Guidelines (2022) and BEPS Action 13 require multinational enterprises to prepare a Local File for each jurisdiction with material related-party transactions. Chapter V outlines that the Local File must include detailed financial data, descriptions of controlled transactions, functional analyses, and applied transfer pricing methods. It complements the Master File by linking global policies to local implementation. Together, these documents ensure that profits are reported where value is created and that local authorities can verify compliance with the arm’s length principle.
