Transfer Pricing Regulations: Defining Associated Enterprises under OECD Guidelines

For multinational corporations, identifying associated enterprises is essential to applying the arm’s length principle to intercompany transactions. This ensures prices align with those used between unrelated parties, helping to avoid double taxation and stay compliant with complex transfer pricing regulations across global tax jurisdictions.

The OECD guidelines, particularly Article 9 of the Model Tax Convention, define associated enterprises by evaluating influence over management, control, or capital—without specifying a fixed ownership percentage. This broad approach allows flexibility but has also created variation across countries.

1. Fixed vs. Fluid Definitions: A Global Comparison of Transfer Pricing Regulations

Among OECD nations, definitions of associated enterprises fall into two categories:

• Fixed Thresholds: 26 countries use ownership-based tests (e.g., 25% or 50% ownership) to determine association.
• Fluid Criteria: 12 countries, including the United States, Canada, France, and Australia, focus on economic influence, control, or dependence without requiring a specific percentage.

In practice, even countries using fixed thresholds often include anti-abuse rules to capture broader scenarios of influence.

2. Italian Case: Substance Over Form

Italy’s recent transfer pricing case highlighted a fluid approach to determining control. Two companies shared directors but lacked evidence of control or economic subordination. The court ruled there was no association under transfer pricing law, emphasizing the need for actual managerial influence, not just formal links.

This mirrors the OECD’s substance-over-form philosophy, underscoring that controlled transactions require genuine control—not simply ownership.

3. Challenges With Fixed Thresholds

Using ownership-based rules can misclassify relationships. For instance, a 50/50 joint venture might be fiercely independent in operations, yet it would be treated as “associated” under fixed-threshold rules, triggering extensive transfer pricing documentation requirements and exposing parties to audit and transfer pricing risks.

4. Fluid Definitions: A Better Economic Lens

Fluid-model countries assess real-world influence over decision-making, contractual obligations, and financial outcomes. This makes transfer pricing method application more accurate and reduces unnecessary compliance burdens when no genuine control exists.

However, it also demands greater evidence-gathering—from board minutes to transaction-level analysis—to show that transactions meet market price expectations.

5. Documentation and Methodology Requirements to comply with Transfer Pricing Regulations

Regardless of the model, tax authorities worldwide expect comprehensive transfer pricing documentation. This includes:

• A Master File outlining the group’s global business;
• A Local File documenting local intercompany transactions and pricing logic;
• A Country-by-Country Report (CbCR) detailing global tax allocations, profits, and activities.

Firms must defend their transfer pricing method—be it CUP, TNMM, or Profit Split—ensuring that goods and services exchanged across borders are priced as if between unrelated parties.

6. Avoiding Transfer Pricing Adjustments

Inaccurate association determinations can result in unwarranted transfer pricing adjustments, leading to increased tax liabilities, disputes with tax authorities, and possible double taxation. Especially in cross-border dealings, reconciling differences between jurisdictions with fixed vs. fluid definitions is essential.

Conclusion

The definition of “associated enterprises” lies at the heart of global tax compliance. Whether through fixed thresholds or fluid economic influence, companies must ensure their intercompany transactions reflect market prices and follow the arm’s length principle. The Primo Piatto case and OECD’s guidance underscore the importance of substance, not form.
