ZAMBIA Trends and Developments Contributed by: Mulenga Chiteba, Constance Namatai Mwango and Diana Chisale, Mulenga Mundashi Legal Practitioners
Courts had not clearly articulated whether OECD con - cepts such as the “most appropriate method” rule or detailed comparability factor formed part of Zambian law. In Nestlé , the Court engaged directly with OECD- derived analytical constructs, using them to demon - strate the application of domestic statutory provisions Although the Court did not suggest that OECD instru - ments override legislation, it treated them as persua - sive authority in circumstances where the statute is expressed in general terms. This is jurisprudentially significant. It means that: • international guidance may shape the interpretation of Zambian tax law; • future litigants will increasingly anchor arguments in OECD doctrine; and • the ZRA’s internal audit manuals are likely to align more closely with BEPS-inspired standards. In effect, Zambia’s courts have incorporated global best practice into domestic law through judicial inter - pretation rather than legislative transposition. The ZRA historically exercised broad discretion in substituting prices, margins, or even re-characterising transactions. Challenges often failed because taxpay - ers could not show that the authority had acted unlaw - fully rather than merely harshly. There was little guidance on whether the ZRA was obliged to explain why a particular transfer pricing method, such as the transactional net margin method (TNMM) or comparable uncontrolled price (CUP), was preferable to alternatives. Conclusion The decision of the Supreme Court in Zambia Rev- enue Authority v Nestlé Zambia Limited represents a watershed moment in the evolution of Zambian trans - fer pricing law. As demonstrated above, the judgment moves the country decisively away from a regime dominated by administrative discretion and limited jurisprudential oversight toward one characterised by economically rigorous, court-supervised application of the arm’s-length principle.
Through its treatment of functional analysis and risk allocation, the Court entrenched a substance-based conception of related-party pricing, requiring that profits be aligned with real economic activity rather than contractual form. Its endorsement of transaction aggregation where dealings are commercially interde - pendent reflects appreciation of modern multination - al business models and ensures that benchmarking exercises capture the full commercial context in which value is created. Equally significant is the Court’s approach to com - parability. By rejecting both the rigid insistence on purely local benchmarks and the uncritical use of dis - tant foreign comparables, the judgment articulates a balanced doctrine grounded in economic equivalence and reliable adjustment. This approach strengthens the integrity of transfer pricing analysis while recognis - ing the data constraints endemic to developing econ - omies. The recalibration of evidentiary burdens further reinforces this trajectory: taxpayers must substantiate their pricing with robust contemporaneous documen - tation, but the ZRA is now judicially required to justify its methodological choices and engage transparently with competing economic analyses. The Court’s reliance on the OECD Transfer Pric - ing Guidelines as a persuasive interpretive authority consolidates Zambia’s alignment with international norms, even in the absence of wholesale legislative incorporation. This jurisprudential openness to global best practice is likely to shape both audit practice and future litigation, embedding BEPS-inspired standards into domestic administration. Taken together, these developments indicate that Zambia has entered a new era of transfer pricing governance; one in which legal certainty, analytical discipline, and judicial oversight operate as counter - weights to aggressive revenue protection strategies. For multinational enterprises, the message is clear that transfer pricing policies must be defensible at both economic and legal levels, supported by cred - ible benchmarking and detailed functional analysis. For the ZRA, the judgment affirms its mandate to pro - tect the tax base, but only through methodologies that withstand close judicial scrutiny.
