Background -
Stellantis Portugal, S.A, a Portuguese vehicle distributor operating within the Stellantis multinational group (formerly General Motors group) was subject to a tax audit that led to litigation before the Portuguese courts. The central question was whether a year-end transfer pricing adjustment, made purely for corporate income tax purposes to ensure compliance with the arm's length principle, could also carry consequences for Value Added Tax (VAT).
Under the group's distribution arrangement, the sale prices of vehicles were structured to be adjustable, ensuring the distributor maintained a minimum profit margin. When actual margins fell short of the contractually agreed threshold, the related manufacturers within the General Motors group issued debit or credit notes to Stellantis Portugal to reallocate profits accordingly.
The core dispute was whether such adjustments which do not alter individual transaction unit prices but instead reallocate group-level profits should be treated for VAT purposes as:
a) a retroactive correction to the consideration for earlier goods supplies, reducing or increasing the taxable amount; or
b) the consideration for a separate supply of services, thereby constituting an independent taxable event.
The Supremo Tribunal Administrativo (Portugal's Supreme Administrative Court) referred the matter to the Court of Justice of the European Union (CJEU) by way of a preliminary ruling request, asking for an interpretation of Article 2 of the Sixth VAT Directive.
Assessee's Position | Revenue / Tax Authority's Position | Advocate General's Analysis |
|---|---|---|
The year-end profit adjustments were made exclusively for income tax purposes to align with the arm's length principle. They do not represent separate supplies of services and should carry no VAT implications. | The adjustments implemented through debit/credit notes between related group companies may constitute taxable transactions for VAT, as they form part of the contractual arrangement governing the supply of vehicles. | The VAT relevance of a TP adjustment depends on its nature and mechanism. Adjustments made through separate supplies of services for consideration (creating input/output) constitute taxable transactions under Article 2(1)(c) of Directive 2006/112/EC. |
The adjustments were implemented via credit/debit notes in the context of ensuring a minimum profit margin, not as separate service fees. There is no identifiable service being rendered that would trigger a VAT charge. | The contractual arrangement specifically provided for variable pricing tied to profit margin targets. This agreed variability in price, documented through formal notes, may give rise to VAT obligations regardless of the income tax motivation behind the adjustment. | Where a profit adjustment is made unilaterally by a tax authority solely for purposes of allocating profits between two taxing jurisdictions, it is generally not relevant for VAT. Such administrative reallocation does not involve a supply. |
Even if the adjustments are viewed as price corrections, they should be treated as a reduction in the taxable amount of prior goods supplies and not as separate newly taxable supplies. The Hamamatsu precedent supports this view. | The adjustment falls outside the simple price-correction framework and must be examined in light of the overall contractual architecture, which anticipates and formalises the profit margin mechanism as a core commercial term. | Where the adjustment is made pursuant to a contractually agreed variable price directly related to a specific supply of goods, it constitutes either a reduction in the taxable amount (Article 90, Directive 2006/112) or an additional part of the consideration (Article 73), and cannot itself constitute a separate supply of services under Article 2(1)(c). |
Advocate General's Opinion -
The Advocate General proposed that the CJEU answer the preliminary reference as follows: the VAT relevance of a transfer pricing profit adjustment depends entirely on its underlying structure and the manner in which it is executed. Three distinct scenarios were identified:
Scenario 1 - Services-based adjustment: Where the adjustment is implemented through separate, genuine supplies of services for consideration (i.e., real input/output flows), those supplies are taxable transactions under Article 2(1)(c) of Directive 2006/112.
Scenario 2 - Unilateral tax authority reallocation: Where the adjustment is made unilaterally by a tax authority purely to allocate profits appropriately between two jurisdictions, this is not as a general rule, relevant for VAT purposes.
Scenario 3 - Contractually agreed variable price (present case): Where the profit adjustment is made via a sale price specifically provided for and agreed to be variable, relating to a specific supply of goods, it constitutes a correction to the taxable amount under Article 90 or an additional element of consideration under Article 73 and cannot, by itself, constitute a supply of services under Article 2(1)(c).
The Advocate General proposed that Articles 2(1)(c), 73 and 90 of Council Directive 2006/112/EC must be interpreted as follows -
1) The VAT relevance of a transfer pricing profit adjustment depends on what it relates to and how it is made, not merely on whether it is described as a TP adjustment or was motivated by income tax considerations.
2) Adjustments structured as genuine separate supplies of services for consideration are taxable under Article 2(1)(c), provided they are not merely fictitious.
3) A unilateral reallocation by tax authorities for inter-jurisdictional profit allocation purposes is generally not VAT-relevant, as it does not involve a supply.
4) Where, as in the present case, the adjustment is implemented through a contractually variable sale price tied to a specific goods supply, it constitutes either a reduction in the taxable amount (Article 90) or an additional element of consideration (Article 73) and cannot itself constitute a supply of services under Article 2(1)(c).
