TP adjustments and VAT: lessons from Stellantis Portugal

Profit allocation is not necessarily payment for a service.

The recent CJEU ruling in Stellantis Portugal (Case C-603/24) helps clarify the interaction between Transfer Pricing (TP) adjustments and VAT – an area of long-standing uncertainty for multinational groups.

The court – in agreement with AG Kokott’s opinion in that case and consistent with the CJEU’s decision in Arcomet (Case C-726/23) – confirms that TP adjustments are only consideration for a separate taxable supply if there is a direct link between the adjustments and the supply, within a legal relationship involving reciprocal performance. The contractual framework governing the arrangement will be critical to whether there is a direct link. Whether or not there is a separate supply, it remains a question of assessment whether the TP adjustments themselves should be treated as adjusting, for VAT purposes, the consideration for the original supply (requiring corresponding VAT credit and debit notes).

Under an intragroup agreement, Stellantis Portugal (formerly General Motors Portugal, ‘GMP’) bought vehicles from group OEMs (original equipment manufacturers), and resold them to third-party dealers in Portugal. The agreement was designed to leave GMP with a target operating margin. The initial sale price was based on projected external sales prices and included GMP’s operating and distribution costs, including warranty repair costs recharged by third-party dealers. When those costs were incurred, GMP notified the OEM and the sale price was adjusted via credit and debit notes (the ‘TP adjustments’) to achieve the target margin. The Portuguese tax authorities treated the adjustments as consideration for separate taxable repair services supplied by GMP to the OEMs, issuing VAT assessments exceeding €1.5m.

AG Kokott identified and opined on three relevant scenarios. First, where genuine services are contractually agreed and supplied in return for the TP adjustment, they are taxable. Second, unilateral adjustments to transfer prices only do not alter the contractually agreed consideration and therefore have no VAT consequences. Thirdly, for contractual variable price mechanisms where the price is ‘undetermined but determinable’ (as was the case for GMP), TP adjustments alter the consideration for the existing supply and should follow its VAT treatment.

The CJEU confirmed that adjustments to a transfer price under an intragroup profit allocation arrangement do not represent consideration for a separate taxable supply unless there is a direct link between the supply and the adjustment. On the facts, there was no direct link between the TP adjustments and the vehicle repairs: (i) the intragroup agreement concerned only vehicle pricing and did not provide for GMP to perform repair (or other) services to the OEMs; (ii) the margin adjustments reflected GMP’s entire operating cost base, not just repair costs; and (iii) the TP adjustments were uncertain and bi-directional (and might not materialise at all if the target margin was already achieved). Had the arrangement instead provided for reciprocal obligations of identifiable services in exchange for the TP adjustments (as in Arcomet), those services might have constituted a separate supply.

Stellantis Portugal therefore provides helpful clarity and a further basis for taxpayers to resist tax authority challenges to the VAT treatment of TP adjustments where there is no supply of goods or services linked to those adjustments. Arcomet, however, shows that once there is a distinct service, a direct link can be inferred. Both cases emphasise the importance of contractual drafting. Taxpayers should ensure intragroup agreements clearly explain the basis of price adjustments, and consider VAT implications when implementing TP models.
