The OECD Transfer Pricing Guidelines (2022) provide the primary international framework for pricing intercompany transactions under the arm’s length principle. They emphasize the importance of comparability, functional analysis, and reliable documentation in determining fair transfer prices. Chapter I defines how to assess the functions, assets, and risks involved, while Chapter II details acceptable pricing methods. Together, they ensure that transactions between related entities are structured, tested, and reported consistently, with profits aligned to value creation and economic substance across all jurisdictions.
