The facts
When vehicles showed defects, for example factory defects, warranty cases or roadside assistance issues, the dealers carried out the repairs. Those repairs were invoiced, with VAT, to Stellantis Portugal.
Within the group, a transfer pricing agreement was in place. The purpose of that agreement was to guarantee Stellantis Portugal a predetermined profit margin on the resale of the vehicles. The internal purchase price of the vehicles was therefore adjusted afterwards through credit notes or debit notes issued by the group manufacturers.
The Portuguese tax authorities argued that this adjustment was not merely an ordinary price correction. According to the authorities, Stellantis Portugal supplied repair services to the manufacturers and the transfer pricing adjustment constituted the consideration for those services. On that basis, additional VAT was assessed.
What did the Court decide?
The only relevant agreement was the transfer pricing agreement. That agreement concerned the determination of internal purchase prices and the guarantee of a predetermined profit margin. It did not contain any clear obligation for Stellantis Portugal to provide repair services to the manufacturers for consideration.
That is an important point. A pricing mechanism is not the same as a service contract.
The calculation method of the adjustment also played an important role. The repair costs were only one element in a broader formula. The adjustment also took into account other distribution costs, such as personnel, electricity and marketing expenses. In addition, the mechanism could result either in a credit note or in a debit note.
As a result, the connection between the possible repair services and the transfer pricing adjustment was at most indirect. An indirect connection is not sufficient for VAT purposes.
The Court therefore concluded that such a transfer pricing adjustment does not constitute consideration for a supply of services for consideration, unless there is in fact a legal relationship between the group entities involving reciprocal obligations, whereby one entity performs identifiable services and the other pays consideration for those services through the adjustment.
Not automatically a supply of services, but neither automatically outside the scope of VAT
The judgment does not mean that transfer pricing adjustments always fall outside the scope of VAT.
The correct question is therefore not merely whether a payment takes place. The real question is what exactly is being adjusted.
Is it:
The judgment follows the same reasoning as Advocate General Kokott’s Opinion of 15 January 2026. There too, the central point was that a transfer pricing adjustment cannot automatically be treated as one particular type of transaction. The legal and economic reality of the adjustment must first be identified.
Connection with Arcomet
Stellantis must be read against the background of Arcomet Towercranes, C-726/23.
In Arcomet, the Court accepted that a transfer pricing adjustment could be linked to services. That was largely because, according to the referring court, the arrangement concerned central support services supplied by the parent company to the subsidiary.
Stellantis now introduces an important nuance. Arcomet should not be interpreted as meaning that every transfer pricing correction automatically constitutes consideration for a service. Everything depends on the underlying legal relationship.
Whereas Arcomet involved a genuine service framework, Stellantis primarily concerned a pricing mechanism for vehicles intended to achieve a predetermined target margin. That distinction is decisive.
Practical implications
For businesses working with periodic true-ups, documentation becomes even more important. Contracts, transfer pricing policies, pricing formulas, credit notes, debit notes and internal documentation must collectively provide a coherent picture of what exactly is being corrected.
If the correction is intended as an adjustment to the price of previously supplied goods, that should also be reflected in the contractual arrangements and accounting treatment.
Conversely, where it is argued that a service exists, it must be clear which service is supplied, by whom, for whom, and why the payment constitutes the actual consideration for that service.
The mere inclusion of certain costs in a transfer pricing formula is not sufficient. Costs may be relevant in calculating a price, but they do not in themselves constitute a VAT supply. They therefore do not automatically turn the cost bearer into a service provider.
Commentary
The value of Stellantis does not lie in establishing a general rule that transfer pricing corrections fall outside the scope of VAT. The judgment does not go that far.
Its importance lies mainly in the fact that it brings the analysis back to its proper starting point. For VAT purposes, the decisive factor is not that settlement takes place, but why settlement takes place.
That question must be answered on the basis of the legal and economic reality. What does the correction actually represent? A separate service? An adjustment to an earlier price? Or merely a correction of the group profit allocation?
In that sense, Stellantis introduces a useful nuance into the debate following Arcomet. A transfer pricing correction may still constitute consideration for a separate service, but only where it is clear which identifiable supply is made and why the consideration is directly linked to that supply.
In other words: not every transfer pricing true-up is a service. But every true-up still requires its own VAT analysis.
Stellantis Portugal, formerly Opel Portugal and previously General Motors Portugal, acted as the national distribution company within the General Motors group. It purchased vehicles from group manufacturers and resold them to independent Portuguese dealers.
When vehicles showed defects, for example factory defects, warranty cases or roadside assistance issues, the dealers carried out the repairs. Those repairs were invoiced, with VAT, to Stellantis Portugal.
Within the group, a transfer pricing agreement was in place. The purpose of that agreement was to guarantee Stellantis Portugal a predetermined profit margin on the resale of the vehicles. The internal purchase price of the vehicles was therefore adjusted afterwards through credit notes or debit notes issued by the group manufacturers.
The Portuguese tax authorities argued that this adjustment was not merely an ordinary price correction. According to the authorities, Stellantis Portugal supplied repair services to the manufacturers and the transfer pricing adjustment constituted the consideration for those services. On that basis, additional VAT was assessed.
What did the Court decide?
The Court did not start from the question of who paid whom. The first question is whether a legal relationship exists between the group companies under which reciprocal supplies are exchanged. According to the Court, that was not the case.
The only relevant agreement was the transfer pricing agreement. That agreement concerned the determination of internal purchase prices and the guarantee of a predetermined profit margin. It did not contain any clear obligation for Stellantis Portugal to provide repair services to the manufacturers for consideration.
That is an important point. A pricing mechanism is not the same as a service contract.
The calculation method of the adjustment also played an important role. The repair costs were only one element in a broader formula.

The Court therefore concluded that such a transfer pricing adjustment does not constitute consideration for a supply of services for consideration, unless there is in fact a legal relationship between the group entities involving reciprocal obligations, whereby one entity performs identifiable services and the other pays consideration for those services through the adjustment.
Not automatically a supply of services, but neither automatically outside the scope of VAT
The judgment does not mean that transfer pricing adjustments always fall outside the scope of VAT.
The Court merely held that, in this case, the adjustment could not automatically be treated as consideration for a separate service. If the national court were to conclude that the adjustment actually constituted a modification of the price paid by Stellantis Portugal for the vehicles, then the impact on the taxable amount would need to be examined separately.
The correct question is therefore not merely whether a payment takes place. The real question is what exactly is being adjusted.
Is it:
- consideration for a separate service;
- an adjustment to the price of previously supplied goods;
- or merely a correction of the group profit position?
That qualification ultimately determines the VAT treatment.
