Transfer pricing and VAT: Court confirms in Stellantis that not every true-up constitutes a service

May 13
On 13 May 2026, the Court of Justice delivered its judgment in Stellantis Portugal, C-603/24. The judgment is important for groups working with transfer pricing adjustments, target margins and periodic true-ups.

The message is clear: a transfer pricing adjustment is not automatically consideration for a separate service. For VAT purposes, it is not sufficient that a payment takes place between related entities. What matters is the actual nature of the payment or adjustment.

A transfer pricing true-up may therefore still have VAT implications, but not because it must automatically be regarded as a service. The qualification depends on the underlying legal relationship, the pricing arrangements and the direct link between the payment and any identifiable supply.
The text presents a careful examination of a VAT question arising from a transfer pricing adjustment within the Stellantis Portugal group. It has notable strengths and some limitations that shape how the decision is interpreted and applied. Strengths - Clear identification of the core issue: The analysis prioritizes whether there is a legal relationship between group entities that creates reciprocal supplies, rather than starting from who paid whom. This helps avoid assuming a service relationship where one may not exist. - Distinction between pricing mechanisms and service contracts: The discussion underscores that a pricing adjustment in itself is not automatically a service contract, which guards against equating accounting adjustments with separate taxable supplies. - Emphasis on economic and legal reality: The judgment centers on what the adjustment actually represents in practical terms, requiring a thorough assessment of the underlying legal relationship and the specific nature of the supply. - Consideration of multiple possible VAT outcomes: The text outlines three potential qualifications for the adjustment (a separate service, an adjustment to the price of goods, or a correction of the profit allocation), showing a nuanced approach rather than a binary conclusion. - Integration with broader jurisprudence: By referencing Arcomet and Advocate General Kokott’s opinion, the analysis situates Stellantis within an evolving framework, highlighting that transfer pricing corrections can be linked to services in some contexts but not automatically. - Practical guidance for businesses: It stresses the importance of comprehensive documentation—contracts, transfer pricing policies, pricing formulas, and accounting records—to support the intended VAT treatment of adjustments. - Balanced takeaway: The conclusion avoids universal rules, instead stressing that VAT treatment depends on the precise nature of the correction and the underlying supply, which can vary case by case. Weaknesses and caveats - Ambiguity in application: While the decision provides a framework, it leaves substantial interpretive space for national courts to determine whether a true-up constitutes a separate service or a price adjustment, potentially leading to inconsistent outcomes across jurisdictions. - Dependence on factual specifics: The analysis hinges on the particular structure of the internal arrangement and the presence or absence of identifiable services, which may be difficult to establish in complex corporate groups. - Potential for over-technical valuation: The discussion highlights that a mere inclusion of costs in a transfer pricing formula is not a service; however, in practice, disentangling cost components and their link to services could be technically challenging and resource-intensive. - Limited predictive certainty: Even with clear documentation, the Court’s approach requires careful, individualized assessment of legal relationships and economic reality, which may delay VAT rulings and create uncertainty for ongoing true-ups. - Future-facing nuance: The reliance on Arcomet and the Advocate General’s opinion suggests a developing area of law; future cases could modify the balance between when a transfer pricing adjustment is treated as a service versus a price correction, affecting long-term planning. - Risk of constrained generalization: While the text provides valuable guidance, firms should avoid assuming that all transfer pricing adjustments will be treated the same way in other contexts or sectors; each scenario demands its own VAT analysis. Overall The analysis contributes a measured, reality-focused view of how transfer pricing corrections interact with VAT. It highlights that the decisive factor is the true nature of the correction rather than its procedural form, promoting thorough documentation and careful differentiation between separate services, price adjustments, and profit-correction mechanisms. At the same time, it acknowledges that outcomes are case-specific and that ongoing jurisprudence may refine the boundaries of when a true-up can be considered a service, underscoring the need for careful, contract-driven VAT planning and analysis.
