The scope and complexity of transfer pricing litigation across the Americas have expanded considerably in recent years, reflecting both the increased sophistication of multinational enterprise (MNE) structures and the strengthening of tax authorities’ enforcement efforts. A review of available case law and publicly reported decisions indicates a growing body of jurisprudence across the region, particularly in larger economies such as the United States, Argentina, Brazil, Canada, Chile, Colombia, Mexico and Peru, with more limited but developing activity in other jurisdictions.
Emerging Topics
Courts are increasingly required to resolve disputes involving complex interactions between legal interpretation, economic analysis, and valuation. Although domestic law remains central, court reasoning in many cases reflects, to varying degrees, the OECD Transfer Pricing Guidelines (2022). Some commonly observed topics are:
- First, the delineation of transactions has emerged as a central concern. Consistent with the principle of substance over form, courts and tax authorities increasingly focus on the parties’ actual conduct rather than focusing exclusively on the contractual arrangements. This is particularly evident in cases involving business restructurings, where the commercial rationality of the restructuring, the termination or renegotiation of pre-existing arrangements, and the allocation of profit potential are subject to scrutiny.
- Second, the valuation of intangibles and the determination of royalty payments remain among the most contested areas. Court analysis in these cases typically relies on established financial valuation techniques, including discounted cash flow (DCF) methods and comparable uncontrolled price (CUP) analyses, applied within the framework of transfer pricing rules. In practice, these techniques are often developed with reference to recognised professional standards, including the International Valuation Standards (IVS), which in a number of jurisdictions serve as a framework for valuations prepared for taxation purposes. A recurrent issue concerns the treatment of entity-specific factors and synergies, with courts examining how such elements should be reflected in arm’s-length pricing.
- Third, intra-group financial transactions have become an increasingly relevant source of controversy. Courts are frequently required to determine whether debt arrangements should be treated as such or recharacterised as equity contributions, based on the economic substance of the transaction and the borrower’s capacity to service the obligation. While OECD guidance provides a general analytical framework, the resolution of these issues ultimately depends on domestic tax principles and local practice.
- Fourth, commodity transactions continue to generate significant litigation, particularly in resource-rich countries. The CUP method is often considered the most appropriate approach, albeit as starting point (pre-adjustments) often relying on quoted prices. However, disputes commonly arise over comparability adjustments, including differences in product characteristics, contractual terms, risk-allocation, volumes, and pricing dates, among other factors.
- Fifth, issues relating to the burden of proof and the robustness of comparability analyses remain foundational. Court decisions often review whether the taxpayer or the tax administration has adequately substantiated the selection and application of comparables, including a detailed functional analysis of the parties involved.
- Finally, intra-group services and cost contribution arrangements (CCAs) remain a source of controversy. Courts assess both the existence of a genuine economic benefit and, in the case of CCAs, the consistency between participants’ contributions and their expected benefits, in accordance with applicable transfer pricing principles.
The Relationship Between Transfer Pricing and Valuation
The evolution of case law in the Americas shows that transfer pricing has evolved into an area that requires integrating legal reasoning with solid economic and valuation methodologies. While the determination of arm’s length outcomes remainsgrounded in tax law and transfer pricing rules, valuation techniques play an important evidentiary and analytical role. In this context, professional valuation frameworks (such as IVS) may further inform the development and support of valuation analyses, providing increased robustness.
Accordingly, MNEs operating in the region must ensure not only that intercompany arrangements are consistent with the arm’s length principle, but also that any supporting economic and valuation analyses are methodologically robust and properly documented, as this is a must if aiming to withstand detailed judicial scrutiny.
