The Court of Justice of the European Union, in its judgment of 13 May 2026 (Case C-603/24, Stellantis Portugal, S.A.), has clarified when a transfer-pricing (TP) adjustment between companies of the same group may constitute the consideration for a supply of services subject to VAT. The conclusion, in plain terms, is direct: not by default. Only where there is a legal relationship with reciprocal commitments and a direct link between an identifiable service and the remuneration consisting in the adjustment, does the latter fall within the scope of article 2.1 of the Sixth Directive (today Council Directive 2006/112/EC).

It is a judgment with significant operational impact for multinational groups that close each financial year with year-end true-up adjustments of transfer prices to secure the margin agreed in internal contractual arrangements.

The regulatory framework

Article 2(1) of the Sixth Directive 77/388/EEC, today article 2(1)(c) of Council Directive 2006/112/EC of 28 November, subjects to VAT the supplies of services carried out for consideration within the territory of a Member State by a taxable person acting as such. The classical case law of the CJEU —Tolsma (C-16/93), MKG-Kraftfahrzeuge-Factoring (C-305/01), Lebara (C-520/10), among others— has required, for there to be a supply for consideration, the concurrence of three elements: a legal relationship between supplier and recipient, reciprocal performances, and a direct link between the service supplied and the consideration received.

In the transfer-pricing arena, those elements are not always self-evident. Year-end adjustments are documented through credit or debit notes issued between related companies to true up the agreed margins; they may incorporate very heterogeneous costs —operating, financial, repair, warranty—; and their quantification typically does not respond to an identifiable individual service but to an aggregate calculation based on a margin agreement.

The case

Stellantis Portugal, S.A. is the Portuguese distributor of the multinational group Stellantis (formerly General Motors). It purchases vehicles from European manufacturing companies of the group and resells them to independent Portuguese dealers, which in turn sell those vehicles to final customers. Transfer prices for the vehicles are initially set on the basis of expected sales. At the close of each reference period, the parties make retrospective adjustments to ensure that Stellantis Portugal achieves a pre-agreed profit margin under the group’s contractual arrangement, taking into account the costs actually incurred —including the costs of third-party repairs of the vehicles sold—.

The question put to the CJEU by the Portuguese referring body (Centro de Arbitragem Administrativa, CAAD) was straightforward: do these adjustments constitute the consideration for a supply of services for consideration rendered by Stellantis Portugal to the intra-EU manufacturer paying the adjustment and, accordingly, are they subject to VAT?

The Portuguese tax authority argued yes. Stellantis argued no.

The ruling

The Court of Justice rejects the position of the Portuguese tax authority. The operative part of the judgment reads as follows:

“Article 2(1) of Council Directive 77/388/EEC of 17 May 1977 […] must be interpreted as meaning that a transfer-pricing adjustment of motor vehicles that is:

— duly provided for in a contract concluded between companies belonging to the same group and intended to guarantee that the company acquiring those vehicles obtains a previously determined profit margin on the resale of those vehicles,

— evidenced by a credit or debit note issued by the selling company in the name of the acquiring company, and

— calculated by reference, in particular, to the costs borne by the latter company in connection with the repair by third parties of those vehicles

does not constitute the consideration for a ‘supply of services for consideration’, within the meaning of that provision, unless there exists, between those companies, a legal relationship characterised by reciprocal commitments the object of which is the supply of services by the acquiring company to the selling company and the payment by the latter of a remuneration for those services in the form of such adjustment, establishing a direct link between the supply of those services and that adjustment.”

The Court thus reformulates the double test already applied in its classic case law and projects it onto the specific scenario of intra-group adjustments.

The reasoning

The CJEU structures its analysis around three axes.

First, the principle. A supply of services for consideration —subject to VAT— exists only where there is a direct link between the service supplied and the consideration actually received. This is the established line since Tolsma. The judgment, without innovating on the principle, applies it to the case at hand.

Second, the first condition: legal relationship with reciprocal performances. The CJEU notes that the 2004 contract between the Stellantis group companies regulated the transfer-pricing system and the adjustment mechanism to guarantee margins to the Portuguese distributor. It did not regulate, in contrast, any obligation on Stellantis Portugal to render specific services to the manufacturer. The consideration of third-party repair costs in the adjustment formula does not equate to a contractual obligation on Stellantis Portugal to manage those repairs on behalf of the manufacturer. The legal relationship with individualisable reciprocal performances is not evidenced.

Third, the second condition: direct and identifiable link. Any service that Stellantis Portugal might be deemed to render to the manufacturer —e.g., management of repairs in the Portuguese market— should carry a non-gratuitous, non-random, easily quantifiable and specific counterpart. The CJEU observes that the transfer-pricing adjustment is calculated incorporating not only repair costs, but also more general operating costs. That dilutes the connection between any possible services and the remuneration consisting in the adjustment. The relationship between any possible services and the adjustment is “at most, indirect”, insufficient to configure a taxable supply.

The consequence is the dismissal of the Portuguese assessment. The adjustment, as structured, is not consideration for services subject to VAT.

Editor’s view

The judgment consolidates an orientation that was already brewing in earlier rulings and provides useful operational criteria. Three critical observations.

First, on the scope of the doctrine. The CJEU does not state that transfer-pricing adjustments are per se irrelevant for VAT. The judgment establishes a substantive test: where adjustments respond to a mere true-up of agreed margins, without an underlying legal relationship defining reciprocal services and a direct link between the service and the remuneration, there is no taxable supply. By elevation, if the group structures the adjustment as consideration for specific services —administration, management, technical support, warranties— with specific identification of the service and its remuneration, the adjustment may fall within the VAT scope. The boundary is contractual and documentary.

Second, on the CIT–VAT interaction. Transfer-pricing adjustments have, by definition, an effect on the corporate income tax base of the group entities. The judgment confirms, accordingly, a key functional distinction: compliance with the arm’s-length principle of article 18 LIS and the OECD TP framework can operate independently of VAT taxation. A CIT TP adjustment does not, automatically, trigger a VAT accrual. The adviser should analyse each tax separately.

Third, on the consequences for multinational groups operating with Spain. The judgment, delivered in a Portuguese case, has effects across the harmonised VAT area, including Spain. Groups with Spanish subsidiaries that practise year-end true-up adjustments —common in the automotive industry, retail with concessions and intra-group B2B services— have a strong argument that those adjustments do not trigger VAT, provided they match the contractual and documentary profile examined by the CJEU. The AEAT cannot, without more, require VAT on adjustments; it must evidence the concurrence of the test elements.

The certainty conclusion is high: the CJEU’s doctrine is binding within the EU and the AEAT cannot, in principle, depart from it. Prudence still requires, however, verifying contractual documentation case by case before ruling out VAT on the adjustment.

Practical consequences

For the tax lead of a multinational group with subsidiaries or permanent establishments in Spain, Stellantis Portugal opens a relevant line of defence and forces a review on three points.

(i) Contractual documentation of the adjustments. The intra-group contract must describe clearly whether the adjustment responds to a mere true-up of margins (not subject) or to consideration for specific services (potentially subject). Mixed clauses are the friction zone. Disaggregating helps: one part of the adjustment as margin true-up, another part —if any— as remuneration for identifiable specific services.

(ii) Credit/debit notes and their material support. The concept appearing on the credit or debit note issued in connection with the adjustment must be consistent with the nature of the flow: if it is a margin true-up, no VAT charge is appropriate; if it is service remuneration, yes. The accounting documentation and the group’s internal documentation should be aligned.

(iii) Position vis-à-vis pending inspections or queries. Groups in discussion with the AEAT about VAT accrual on TP adjustments have, since 13 May 2026, a directly applicable jurisprudential argument. The Stellantis Portugal judgment is invocable in any ongoing procedure and, in all likelihood, in future reviews of unprescribed periods.

(iv) Reviewing standard practice. Those groups which, out of excess prudence, had been charging VAT on year-end margin adjustments —typically the manufacturer charging VAT to the distributor on the debit note— may find themselves with VAT charged in error. Rectification is available under the rules of article 89 LIVA, always within the legal time limits.

The CJEU’s doctrine does not exhaust the question —the intra-OECD debate on TP and VAT remains open, with specific discussions about intangibles and functional services that will reach the Court in future rulings—. But it provides, for the most common scenarios in practice, a clear reference.
