The OECD Transfer Pricing Guidelines (2022) define related parties as entities or individuals under common ownership or control that engage in controlled transactions. The Guidelines emphasize that such transactions must adhere to the arm’s length principle, ensuring pricing reflects independent market behavior. Chapters I and II outline the framework for identifying related parties, analyzing their economic relationships, and applying appropriate transfer pricing methods. The OECD also requires that documentation clearly supports pricing logic, profit allocation, and the economic substance behind each intercompany transaction across all jurisdictions.
